Eternal Marshal object for remoting.

2011-11-01T13:24:00.001-07:00

Got this code from this article

public class CallbackClass : MarshalByRefObject
{ 
   private Form1 _parent = null;
   private bool  _state = false;
   public Form1 Parent { set { _parent = value; }}
   public bool State   { set { lock(this) { _state = value; }}}
   // set a leaseing time for infinity

   public override Object InitializeLifetimeService()
   {
     ILease lease = (ILease)base.InitializeLifetimeService();
     if(lease.CurrentState == LeaseState.Initial)  
     {
        lease.InitialLeaseTime = TimeSpan.FromMinutes(0);
     }
     return lease;
   }

Red X after refresh on DataGrid on C# Winforms

2011-09-18T17:06:00.001-07:00

Got the following solution from this forum entry on the comments

--------

Probem is probably that after you clear datasource it start repainting datagridview and if you start fill it during it, it throw exception.

Problem is that it not seems very good, there is a little blink.

I found just one dirty trick:

Before changing data in datasource set visibility of datagridview to false and after it set visibility to true.

---------------------

Did the following on my binding code:

dataGridViewProcedure.Visible = false;

dataGridViewProcedure.DataSource = procedureList;

dataGridViewProcedure.Visible = true;

"Input Error: There is no script engine for file extension ".js"

2010-11-09T13:29:00.000-08:00

Getting the following error when trying to run NeoBatch:

"Input Error: There is no script engine for file extension ".js"

Found this website which had the answer

which was:

I fixed it! In my case, the problem was caused because a program I had installed (UltraEdit) associated the .js file type with it, which broke the ability to run .js files as scripts. I was able to go into UltraEdit and unassociate .js files with it. Another way would be to right-click on a .js file in Windows Explorer, choose "Open with" and then choose "Choose default program", and make sure the default program is "Microsoft Windows Based Script Host".

Windows Mobile 6.5.3 DTK In Visual Studio 2008

2010-06-29T19:13:00.000-07:00

Got the following information from another blog:

Windows Mobile 6.5.3 DTK In Visual Studio 2008

I can't believe how much of pain getting my core Windows Mobile 6.5 development enviroment setup could be. Here are the hoops I've had to jump through so far. I ran into two really annoying hurdles which I couldn't find a solution for so I thought I'd note down what I did for any other people lucky enough to be in the same boat as yours truly. For the record, I'm trying to write my first 6.5 app for my HTC HD2. That is a WVGA phone which means it has a resolution of 480x800.

Follow up:

Get and install Visual Studio 2008. The latest Microsoft MAPS Development & Design program that I'm a member of only has VS 2010 in it because I'm soooo cutting edge. 2010 doesn't currently allow you to develop for WinMo 6.5 but only the shiney new (as in unreleased) Windows Phone 7.
Download and install the Windows Mobile 6 Professional Refresh SDKs.
Download and install the Windows Mobile 6.5.3 Professional DTKs.

Takes bloody ages to do all of that even though it only takes a few mouse clicks. I read that the difference between the "Standard" and "Professional" versions of the SDK and DTK are that the standard version is for non touch screen devices were as the professional edition is. Since I'm developing for a HTC HD2 which has a touch screen I went with the pro editions for both. So now that's all done it should be a simple case of firing up VS2008, choosing new "Smart Device" project using the 3.5 compact framework and away we go. A-ha! Not so. The next screen lets you pick a target platform. There is no Windows Mobile 6.5 in the selection. This is were the workarounds kick in.

Pick "Windows Mobile 6 Professional SDK" and leave the framework set to 3.5 compact. Well for my project I'm using the 3.5 framework. Choose what you like for that.
Choose "Device Application" since I'm creating a new app from scratch.
Now you're presented with a form that looks like an older WinMo 6 device using the default "classic" skin and form factor.
Not a biggy I hear you say, why not just pick the 6.5 form factor from the "Form Factor" property? Because it's not there, that's why!
OK, ignore that for now, at least we can test run the WinMo 6.5 emulator right? Nope. Look at the emulator dropdown and you won't see it.

What is going on? Well it seems a bunch of things have not been wired up correctly. Time to sort the mess out.

On the main menu choose "Project->Change Target Platform". In the dropdown choose "Windows Mobile 6.5.3 Professional DTK" and then OK.
You'll be told that your project needs to be saved and re-opened so OK that. Now when it opens you can see the 6.5.3 emulators in the dropdown. Hoora!
For me and my HD2 development I chose the "Windows Mobile 6.5.3 Professional WVGA Emulator".
So now we head back to the form properties. When the target platform was changed and it re-opened the project it closed the default form window so I have to re-open that with a quick double click.
Selecting the form and looking at it's properties there is still no WVGA option. WTF? I know, that's what I was like. Seems some silly sausage at MS made a typo. If you look at the Form Factor list you'll see two entries titled "Windows Mobile 6.5.3 Professional Square". How strange you say. Before we proceed make sure you don't have either of the two identically named Square form factors chosen at this point. I'll explain why later on.
Let's make things clearer for future projects. On the main menu do "Tools->Options->Device Tools->Form Factors". Make sure the top dropdown says "Windows Mobile 6.5.3 Professional DTK".
In the list below the dropdown you'll see the two Square entries. Select the first one and hit Properties. On the greyed out "Skin Defaults" area check to see if the width and height are 480x800. If not then check the second Square entry.
Once you've found the right one, get out of the Properties panel and hit the Rename option and change it to be "Windows Mobile 6.5.3 Professional WVGA".
A nice little extra step here is to move out of the "Form Factors" sub category and go up one to the "Devices" area. I set the "Default Device" to be the "Windows Mobile 6.5.3 Professional WVGA Emulator" which means each time I create a new 6.5.3 project it will automatically select the correct emulator. I'll still have to manually pick the correct form factor but I'm fine with that.
Now close VS and re-open it. When you re-load your project and look at the Form Factor dropdown you should now see your renamed WVGA option.
Note that if you had cheated and tried selecting the Square option we renamed earlier before you saved and restarted then you will still see the two Sqaure options. It's very important that you don't pick the Form Factor we renamed before we renamed it.
That's it. You now have a WVGA form to work with at design time and you can also test it in the 6.5.3 WVGA emulator all from within the VS2008 IDE.

So the process for creating a new HD2 application becomes:

Open VS and create a new Windows Professional 6, Device Application.
On the main menu choose "Project->Change Target Platform". In the dropdown choose "Windows Mobile 6.5.3 Professional DTK" and then OK.
Let it save and re-open the project and then manually re-open the design time form screen by double clicking the form CS file.
Then change the Form Factor dropdown to the WVGA option we renamed earlied.
Ready to rumble!

As you can see there are still a few steps to have to do each time but it's not too bad now and only has to be done when creating a new project or converting an old one.

Oracle moving to another server

2010-06-15T11:18:00.000-07:00

Export the database as dmp file.

1 - Add a new user to the database using the web interface on Oracle Express Edition

2 - Run the IMP command on the command line

3 - Select the dmp file

4 - log in as the new user

Note: User and Database is the same thing on Oracle (if you are a SQL developer)

5 - Do everything as default, except the question about importing the whole dmp file.

Attention: triggers are not exported, so we need to select all the triggers on the Oracle SQL Developer. Ask to export to DDL and edit with the new name of the user from the old. Execute the query on the new database and everything should be fine.

Software AG Natural Compiler Structured mode / Report mode

2010-05-20T10:30:00.000-07:00

When running natural you might need to change the mode of the compiler between Structured and Report. Here is how you get to it on the PC version of the Natural compiler:

1-Go to Tools->Session Parameters

a new window will open.

2-Go to "Compiler Options"->"Structured Mode" and now you should be able to check and uncheck the "Structured mode" check box.

I think this is all

How to debug Visual Studio design view

2010-04-29T12:26:00.000-07:00

http://msdn.microsoft.com/en-us/library/5ytx0z24(VS.80).aspx

Here is a copy of the link above:

Windows Forms Programming

Walkthrough: Debugging Custom Windows Forms Controls at Design Time

When you create a custom control, you will often find it necessary to debug its design-time behavior. This is especially true if you are authoring a custom designer for your custom control. For details, see Walkthrough: Creating a Windows Forms Control That Takes Advantage of Visual Studio Design-Time Features.

You can debug your custom controls using Visual Studio, just as you would debug any other .NET Framework classes. The difference is that you will debug a separate instance of Visual Studio that is running your custom control's code

Tasks illustrated in this walkthrough include:

Creating a Windows Forms project to host your custom control
Creating a control library project
Adding a property to your custom control
Adding your custom control to the host form
Setting up the project for design-time debugging
Debugging your custom control at design time

When you are finished, you will have an understanding of the tasks necessary for debugging the design-time behavior of a custom control.

Note
The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Visual Studio Settings.

Creating the Project

The first step is to create the application project. You will use this project to build the application that hosts the custom control.

To create the project

Create a Windows Application project called "DebuggingExample". For details, see How to: Create a Windows Application Project.

Creating a Control Library Project

The next step is to create the control library project and set up the custom control.

To create the control library project

Add a Windows Control Library project to the solution. For details, see Add New Project Dialog Box. Name the project "DebugControlLibrary".
Add a new UserControl item to the DebugControlLibrary project. For details, see How to: Add New Project Items. Give the new source file a base name of "DebugControl".
Using the Solution Explorer, delete the project's default control by deleting the code file with a base name of "UserControl1". For details, see How to: Remove, Delete, and Exclude Items.
Build the solution.

Checkpoint

At this point, you will be able to see your custom control in the Toolbox.

To check your progress

Find the new tab called DebugControlLibrary Components and click to select it. When it opens, you will see your control listed as DebugControl with the default icon beside it.

Adding a Property to Your Custom Control

To demonstrate that your custom control's code is running at design-time, you will add a property and set a breakpoint in the code that implements the property.

To add a property to your custom control

Open DebugControl in the Code Editor. Add the following code to the class definition:

C++

JScript

Copy

This language is not supported, or no code example is available.

C++

JScript

Copy

private string demoStringValue = null; [Browsable(true)] public string DemoString {     get     {         return this.demoStringValue;     }     set     {         demoStringValue = value;     } }

Build the solution.

Adding Your Custom Control to the Host Form

To debug the design-time behavior of your custom control, you will place an instance of the custom control class on a host form.

To add your custom control to the host form

In the "DebuggingExample" project, open Form1 in the Windows Forms Designer.
In the Toolbox, open the DebugControlLibrary Components tab and drag a DebugControl instance onto the form.
Find the DemoString custom property in the Properties window. Note that you can change its value as you would any other property. Also note that when the DemoString property is selected, the property's description string appears at the bottom of the Properties window.

Setting Up the Project for Design-Time Debugging

To debug your custom control's design-time behavior, you will debug a separate instance of Visual Studio that is running your custom control's code.

To set up the project for design-time debugging

Right-click on the DebugControlLibrary project in the Solution Explorer and select Properties.
In the DebugControlLibrary property sheet, select the Debug tab.
In the Start Action section, select Start external program. You will be debugging a separate instance of Visual Studio, so click the ellipsis () button to browse for the Visual Studio IDE. The name of the executable file is devenv.exe, and if you installed to the default location, its path will be "C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\devenv.exe".
Click OK to close the dialog box.
Right-click the DebugControlLibrary project and select Set as StartUp Project to enable this debugging configuration.

Debugging Your Custom Control at Design Time

Now you are ready to debug your custom control as it runs in design mode. When you start the debugging session, a new instance of Visual Studio will be created, and you will use it to load the "DebuggingExample" solution. When you open Form1 in the Forms Designer, an instance of your custom control will be created and will start running.

To debug your custom control at design time

Open the DebugControl source file in the Code Editor and place a breakpoint on the Set accessor of the DemoString property.
Press F5 to start the debugging session. Note that a new instance of Visual Studio is created. You can distinguish between the instances in two ways:
- The debugging instance has the word Running in its title bar
- The debugging instance has the Start button on its Debug toolbar disabled
Your breakpoint is set in the debugging instance.
In the new instance of Visual Studio, open the "DebuggingExample" solution. You can easily find the solution by selecting Recent Projects from the File menu. The "DebuggingExample.sln" solution file will be listed as the most recently used file.
Open Form1 in the Forms Designer and select the DebugControl control.
Change the value of the DemoString property. Note that when you commit the change, the debugging instance of Visual Studio acquires focus and execution stops at your breakpoint. You can single-step through the property accessor just as your would any other code.
When you are finished with your debugging session, you can exit by dismissing the hosted instance of Visual Studio or by clicking the Stop Debugging button in the debugging instance.

Next Steps

Now that you can debug your custom controls at design time, there are many possibilities for expanding your control's interaction with the Visual Studio IDE.

You can use the DesignMode property of the Component class to write code that will only execute at design time. For details, see DesignMode.
There are several attributes you can apply to your control's properties to manipulate your custom control's interaction with the designer. You can find these attributes in theSystem.ComponentModel namespace.
You can write a custom designer for your custom control. This gives you complete control over the design experience using the extensible designer infrastructure exposed by Visual Studio. For details, see Walkthrough: Creating a Windows Forms Control That Takes Advantage of Visual Studio Design-Time Features.

VS2008:

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0\ProjectMRUList

VS2010:

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\ProjectMRUList

You can delete them all the clear the history of the Recent Projects.

I think this is it.

S Getting to search

2010-03-16T13:19:00.000-07:00

Go to Navigator->Tools->CompentsTextSearch->All

Now you can search.

S getting to Schemas

2010-03-02T11:38:00.001-08:00

1 - Select Transporter
2 - Click Tools -> PowerSkel Command Center
3 - Look for PowerSkel Management tab for what type of entry "NATURAL TO C#"

PowerSkel is a collection of Prototype.
Prototype is the small part.

Histogram on Natural

2010-02-26T06:10:00.000-08:00

Histogram is a way to query your indexes on Natural, they are not called Indexes in Natural, but that is the way I see them. Since you choose keys on the Data tables and those keys create this index field, so we can do queries against the keys, this is more for the purpose of doing a count after wards, or getting items that are within a range of items faster. It is all about speed.

Screwdriver (filter)

Column Tab

Component name (double-click)

text_header like 'MAI%' /// this is a case for this instance that the names are MAI

text_header can change names since it was an input when I double clicked the Component Name.

The double click action is getting the name of that field in SQL for the table name so we can create nice SQL statements.

Natural Importing Source Files

2010-02-19T08:58:00.001-08:00

We got inside the Natural interface and we type the following on the command line:

SYSOBJH

That will bring up a wizard that eventually we need to select the file to be imported.

Adding Namespaces to WPF inside XAML

2010-02-04T11:10:00.000-08:00

Here is a code snipet that should go inside the Window element as an attribute.

xmlns:custom="clr-namespace:Dbs.Prodesp.FrameworkLibrary.Domain;assembly=Dbs.Prodesp.FrameworkLibrary"

[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]

2010-01-18T06:54:00.000-08:00

The following command:

[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]

If put above a property will make the property not appear on the designer code. This was used to hide information from the designer, when we were controlling it from somewhere else.

App.config for Designer VS 2008

2010-01-13T09:23:00.000-08:00

So I had a screen that loaded some values from the app.config file. For some reason these were already set when I got to them using the Debug Designer code. And finally by the motion of the Holy Spirit I was able to figure it out. There is a devenv.exe.config file which stores those attributes for the designer.

Look for the file and you will see those settings that you wanted so much.

Debugging the designer

2010-01-13T07:35:00.000-08:00

I have been doing work with the designer with my custom Form and my custom TextBox, but I had problems when the designer would crash on me and I had no idea what was going on. I found this article that talks about this. You can launch another copy of the compiler in Debug mode.

It comes down adding a new project to your solution and doing the following change to the properties of the new project:

And changing Start Action from "Start Project" to "Start external program:" and pointing to "C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe" launches the VS2008 again and this time you can load your project and put break points on the original VS2008 and debbuging it on the fly.

DesignMode C#

2010-01-12T11:00:00.001-08:00

I have created a new control which only needed to run the class to handle the reposition code when we were in design view, but it should deactivate on real time, which on my code would make the custom text box get smaller with each resize.

I just had to do the following call:

if( DesignMode )

{

/// do things for design mode only

}

This worked like a charm.

Why the gotos (Natural)

2010-01-05T11:19:00.000-08:00

Here is a nice trick that Natural has:

ReInput

This command has caused us a lot of problems.

When you normally call a screen (Map) to show up you use the Input command, which will display the map. Say you are going down and you display a lot of maps, you decide you need the last one to show up you can call ReInput. This will cause the last known map to display, however it will jump execution to that point in to the code, the part where you called that map. So if you have some code after that map call it will get executed again.

This is one of the hardest problems on converting a Natural program into another language and is one we will need to deal with it.

OnPaint override on C#

2009-12-23T06:12:00.000-08:00

I was trying to get the OnPaint to work:

protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
e.Graphics.DrawString(Text, this.Font,
new SolidBrush(this.ForeColor),
-1, 0);
}

however this would never get called, so I found the following command on the web that I put on my constructor and it made it all work:

this.SetStyle(ControlStyles.UserPaint, true);

Now I can move stuff around, very cool

A code behind page could not access the members of the page on ASP.Net 3.5. Whenever I tried to access the members on the code it would not show them, as if the cs file behind the page was not seening the page.

After some comparison I noticed that the CodeGen file was missing. I just created a new Class file with the name of the page plus the .Designer.cs at the end. The file got created but it was empty. I just had to add a new control to the page and the CodeGeneration took care of the rest. Now the file behind page works fine.

This is just a note so I will remember it.

Item 1 - Generics implementation check

2009-11-10T12:45:00.000-08:00

if( anyObject is ClassName)

{

/// will be true if the object is an instance of the ClassName

}

-----------------

Now I can create generic interfaces

public interface IMyInterface

{

int GetValue(T myGuy);

}

SQL .Net 3.5 Compact size error

2009-10-27T09:07:00.000-07:00

Got the following error on my database when trying to connect:

TITLE: Connect to Server

------------------------------

Cannot connect to C:\..\CompactDatabase.sdf.

------------------------------

ADDITIONAL INFORMATION:

The database file cannot be found. Check the path to the database. [ Data Source = C:\Temp\CommunicationEventLogData.sdf ] (SQL Server Compact ADO.NET Data Provider)

I knew the SQL .Net 3.5 Compact has a size of 4GB, but my database was only about 260MB, so something was wrong. When I first connect to the database I need to make sure to add the "Max Database Size=4000" line to the ConnectionString to the database.

I think this is all,

Create database for LINQ without using LINQ, but instead using bak file from SQL.

2009-09-28T07:03:00.000-07:00

I found here a nice code for .Net 3.5 to get the database up and running from a bak file:

using Microsoft.SqlServer.Management.Smo;

string backupFile="Backupfile";//.bak file

string dbName = "DBName";

string dbServerMachineName = "MachineName";

Microsoft.SqlServer.Management.Smo.Server server = new Microsoft.SqlServer.Management.Smo.Server(dbServerMachineName);

Database database = new Database(server, dbName);

//If Need

database.Create();

database.Refresh();

//Restoring

Restore restore = new Restore();

restore.NoRecovery = false;

restore.Action = RestoreActionType.Database;

BackupDeviceItem bdi = default(BackupDeviceItem);

bdi = new BackupDeviceItem(backupFile, DeviceType.File);

restore.Devices.Add(bdi);

restore.Database = dbName;

restore.ReplaceDatabase = true;

restore.PercentCompleteNotification = 10;

restore.SqlRestore(server);

database.Refresh();

database.SetOnline();

server.Refresh();

The reason for using this is because LINQ will not move over the indexes, and it turns out I need them, so the CreateDatabase method is useless on LINQ right now, who knows in the future MS fixes this.

WPF ListView binding

2009-06-04T16:33:00.000-07:00

Found this blog about the WPF List View binding

So I have a class:

Class Table

{

public string FirstName{get;set;}

public string LastName{get;set;}

public DateTime BirthDate{get;set;}

}

Then I have the list:

List TableList {get;set;}

My WPF window are

"<"ListView ItemsSource="{Binding Path=Table}"">"

"<"ListView.View">"

"<"GridView">"

"<"GridViewColumn Header="Employee ID" DisplayMemberBinding="{Binding Path=EmployeeID}"/">"

"<"GridViewColumn Header="First Name" DisplayMemberBinding="{Binding Path=FirstName}"/">"

"<"GridViewColumn Header="Last Name" DisplayMemberBinding="{Binding Path=LastName}"/">"

"<"GridViewColumn Header="BirthDate" DisplayMemberBinding="{Binding Path=BirthDate}"/">"

"<"GridViewColumn Header="City" DisplayMemberBinding="{Binding Path=City}"/">"

"<"GridViewColumn Header="Country" DisplayMemberBinding="{Binding Path=Country}"/">"

"<"/GridView">"

"<"/ListView.View">"

"<"/ListView">"

MyListView.DataContext = TableList;

All done

WPF TextBox not typing

2009-06-03T08:53:00.001-07:00

I was trying to get the TextBox to type after opening the WPF window from a WinForm and the text box would not get any of the keyboard events. Looking around I found the following fix:

WindowMeterSelection windowMeterSelection = new WindowMeterSelection();

System.Windows.Forms.Integration.ElementHost.EnableModelessKeyboardInterop(windowMeterSelection);

windowMeterSelection.Show();

FIX: When you undock some windows or change the window layout in the Visual Studio 2008 Service Pack 1 IDE, the IDE crashes

/Grid

And that is it... all done.

Singles on LINQ

2009-04-29T09:11:00.000-07:00

So we can do one line queries to getting the exact product back.

So we can do an initialization of fields from the contructor

OrderDetail li1 = new OrderDetail() { Product = chai, Quantity = 23 };

WPF ListView keep at last one added visible

2009-04-25T12:14:00.001-07:00

This simple command focus the ListView for WPF into the last possition:

Socket timeout exception disconnects the Socket.

2009-04-03T13:40:00.000-07:00

Very fun stuff...

I found out that whenever you set your Socket to a timeout period and you are not using async sockets you get a socket exception for your timeout. Which was fine, but I found that the exception cause the socket to disconnect. Nasty since I am working with AT&T network and if you disconnect your socket you need to wait 60 seconds before you can try again. I had to somehow not let the Socket.Receive(buffer) throw that exception, the solution? I check to see if there is anything to receive before I receive.

// initialize your socket.

// send information through socket

/// this is for how long do we process information

int intervalSpacing = 10;

/// keep looping until we get information or the timeout runs out.

while (!_socket.Poll(intervalSpacing, SelectMode.SelectRead) && (internalTimeout > 0))

{

internalTimeout -= intervalSpacing;

Thread.Sleep(intervalSpacing);

}

/// if our timeout is 0 or less than

/// than we ran out of time.

if (internalTimeout <= 0)

{

/// handle the time out here, the socket is still active.

}

else

{

/// buffer for the received data

byte[] buffer = new byte[1024];

/// get the data

int dataReceived = _socket.Receive(buffer); /// this is where I would get my exception before

/// handle the processing of the data here

}

The trick here was just add that Pool call before I did my synced receive.

C# .Net 3.5 Socket issue after timeout

2009-03-27T11:52:00.001-07:00

Here is the scenario.
My communication times out on receive.
I set a time out period of about 2 seconds then I call:

_socket.Receive(buffer);

Which is fine. I get a SocketException with the message "A connection attempt failed because the connected party did not properly respond after a period of time"

The problem comes when I try to receive again. Basically when I time out I am supposed to retry for a certain count. So I send the last packet again fine using the same _socket class, but when I attempt to Receive again I get a SocketException where the message is "A non-blocking socket operation could not be completed immediately" immediately after the call.

If I do disconnect and connect again I am fine. So now I will keep adding to comments as I find new things about this issue.

WDS Hell

2009-03-13T19:34:00.000-07:00

For the last 48 hours I have been trying to make this piece of crap work.

I have a Windows 2003 which is running WDS (Windows Deployment Server) and trying to get it working.

First the new machine booting in PXE would not even see it.

It is a x64 machine so I had to run the following command:

WDSUTIL /set-server /architecturediscovery:yes

This would get me to an error that gave me

\Boot\BCD

error 0xc000000f

Then I basically got fed up got to my remote install folder and just shared and security user "everyone" full rights. After that I got the Windows 2008 x64 to install on the machine.

Got this far, but now Windows 2008 wants the Network card drivers. I need to create a new image with the drivers in it? The driver will not give me a driver file because it is contained inside a .exe file which detects if I am running a x64 machine. Ok I give up. This machine can do a SATA DVD Drive. I am going to do that instead.

Sorry if you came here for a solution, perhaps my notes above might help you, but I am giving up on this. WDS is too complicated, that would mean I would need to have the driver for every machine that I install I would need to create a new image. That is too much hasle. Why couldn't they install using the same driver they used to communicate to the WDS.

Oh well.

God bless,

More information easy to understand on Remoting and Events

2009-01-26T14:52:00.000-08:00

http://dotnetjunkies.com/Tutorial/BFB598D4-0CC8-4392-893D-30252E2B3283.dcik

only problem is this guy is on VB... so I had to try to understand his code which in theory should translate to C# very easily.

Events on Remoting .Net 3.5

2009-01-22T08:42:00.001-08:00

I have been trying to get the events to work on the remoting side of things. However every time I tried to get the event to link on a remote like the following:

m_RemoteObject.myevent += new myeventhandler(sink.myCallback);

it would throw me an exception saying ""Type System.DelegateSerializationHolder and the types derived from it (such as System.DelegateSerializationHolder) are not permitted to be deserialized at this security level."

After much research I found the following post:

http://groups.google.com/group/microsoft.public.dotnet.framework.remoting/browse_thread/thread/264fe6bd76f8cced?pli=1

Which had the gem inside:

In server side, need to set the "typeFilterLevel=Full" in the server

channel, the following code is for TCPchannel.

Search "typeFilterLevel","Full","Event" in google can find many information.

IDictionary providerProps = new Hashtable();

providerProps["typeFilterLevel"] = "Full";

BinaryServerFormatterSinkProvider provider = new BinaryServerFormatterSinkProvider(providerProps, null);

IDictionary props = new Hashtable();

props["port"] = 9999;

TcpChannel tcpChannel = new TcpChannel(props, null, provider); //open a channel

And that was it...

Auto Scroll on ListView C# .Net 3.5

2008-08-04T15:54:00.000-07:00

myListView.Items[myListView.Items.Count - 1].EnsureVisible();

Iteration through enumeration

2008-08-04T14:31:00.000-07:00

I was wondering how I could get all the value of a enumeration, so I found the nice Enum class on C# .Net 3.5.

Here is a quick code:


namespace ConsoleSandBox2
{
    enum Animals
    {
        Cat = 0,
        Dog = 1,
        Bird = 5
    }

    class Program
    {
        static void Main(string[] args)
        {

            /// does not really mater which one you pick here.
            Animals animals = Animals.Cat;

            /// stores the name and numbers of each entry
            Array animalArray = Enum.GetValues(animals.GetType());

            Console.WriteLine("Contents of all the items inside Animals");

            for (int count = 0; count < animalArray.Length; count++)
            {
                /// now it prints  
                Console.WriteLine((int)animalArray.GetValue(count) + " " + animalArray.GetValue(count).ToString());
            }

            Console.WriteLine("Done");

            /// just for a pause
            Console.Read();
}
}


output:
Contents of all the items inside Animals
0 Cat
1 Dog
5 Bird
Done

MarshalByRefObject with eternal life against Garbage Collection

2008-08-04T13:47:00.000-07:00

If you create a Remoting object and it needs to stay alive and all its member what you need to do is just add the following override method call to it.


public override object InitializeLifetimeService()

Serializating and Deserializing manually

2008-05-02T09:59:00.000-07:00

These are the methods to make a class have some fields or processes that are done manually when the object is ready to be serialized and decerialized on the other side.

[OnSerializing]
///

/// When the object is asked to serialize we need to save the information about
/// the Linq object, since it cannot be serialized normally.
///

void OnSerializing1(StreamingContext context)
{
/// do your serialization stuff here
}

[OnDeserialized]
///

/// When the object is asked to serialize we need to save the information about
/// the Linq object, since it cannot be serialized normally.
///

void OnDeserialized(StreamingContext context)
{
/// do your deserialization stuff here
}

Must add the following using to the class doing this.
using System.Runtime.Serialization;

Debugger display

2008-05-01T11:56:00.000-07:00

[DebuggerDisplay("{ToDebugString()}")]
public class MyClass

{
return "My own whatever I want to display on the debug screen";
}
}
This is for when the class is in debug mode we can display whatever we want.

Trying to create a proxy to an unbound type.

2008-04-30T10:59:00.000-07:00

While doing remoting on .Net 3.5 and I am pretty sure this applies to .Net 3.0, 2.0, and possibly 1.0.

I got the error "Trying to create a proxy to an unbound type." Which basically means the object I was trying to remote was not inheriting the MarshalByRefObject class, which made the class not able to be referenced by the remote command.

Got this information from this forum entry.

I am currently working in a new install of vs2005 and i am used to the solutiion explorer automatically highlighting the active file, so if i am editing someclass.cs, it would highlight that file within the solution explorer, however it is currently not doing this. is this a setting somewhere?

CColeman88,
-----------------------------------
CColeman88,

There is a setting. Go to Tools | Options | Projects and Solutions and check the box for 'Track Active Item in Solution Explorer'. Another cool tip while you're there is to uncheck the 'Save new projects when created' box (more info).

Hope this helps,

QUOTE(Binooplal @ Thu Oct 5 2006, 09:31)

Hi All,If your Linksys Skype phone CIT 200 is showing UNREGISTERED

do these steps:
1. Press and hold the button on the base station until the blue light starts blinking.
2. In handset go to SYSTEM menu and select REGISTER.
Default pin is 0000

Have a good time.Binooplal
P.IEmail: Binooplal@hotmail.com

Well, it's not enough to say one should push and hold the base paging button. Because if you press it for 2-3 seconds, the blue Led will start blinking immediately, but at a slow pace. In fact the Base just tries (unsuccessfully) to page the handset.
In fact, YOU MUST HOLD THE PAGING BUTTON FOR AT LEAST 10 SECONDS

The blue led starts blinking then at a much faster pace, and that's the whole difference. The Base switches then in another Mode. I've spent my whole afternoon failing to register my handset because i didn't know this small detail.It's very important because the Linksys chat-support team didn't even know about the 10 seconds thing and will just ask you to press (and hold till it blinks) the paging button, not specifying it needs to be done for 10 seconds.I hope my feedback will help a lot of you out there. Rest of procedure advised by Binooplal is appropriate (including PIN 0000) and should be followed.By the way, if you experience the now famous EACCESSVIOLATION bug with your linksys CIT200, here's the solution :
1) close the CIT200 application on your PC
2) check in taskmanager (press ctrl+alt+del) if CIT200 process is still running. If yes, terminate the process.
3) close Skype (it's very important, otherwise the bug will remain)
4) Re-open manually the CIT200 application, it will automatically re-initialize both the USB CIT200 base and re-open skype software.The EAccessViolation occurs quite often to me (at least once a week so far, for the past 4 months). There's no specific reason why it happens i could identify.
But it always starts with the following :

- CIT200 Handset displays "OFFLINE"- While Skype software displays "ONLINE"This conflict of interest between the CIT200 application and the Skype application makes it impossible to place or receive any phone call. It's even more bothering than it may happen anytime for no reason. But at least you know now how to deal with it.In case my method doesn't work with your system, the ultimate solution is to reboot your computer, everything should be working back to normal, until next bug.I have to acknowledge that I'm very happy with this product - great sound and range - but Linksys should definately make it more obvious for cutomers to fix these bugs as i found a lot of users out there were experiencing these 2 same issues. While chating with the Linksys support, the ultimate answer i received from them was to RETURN the product (!) for exchange, as we spent more than 1 hour failing to register my handset (because of the 10 seconds thing they didn't know). It's no surprise some users are so desperate they consider switching to NEXTGEAR (competitor brand). It's for sure not a good marketing strategy from Linksys to setup such a great product with no matching help support on their own website. I asked them to do so and at least mention these 2 topics, i hope they will.

One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project.

2007-08-07T12:58:00.000-07:00

My project was working fine, then I did some modification and I start getting the following error on a derived FormControl class from a Base FormControl. This was doing inside the Visual Studio 2005 desing view of the derived FormControl

"One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes."

If I were to run the program the derived FormControl would display fine at run time, so what was the problem at design time?

I had added a new parameter to be passed down to the Base FormControl to some different behavior, so now I did not have a empty constructor anymore, and basically this is what was causing this behavior, without a default "empty" constructor the design view could not run.

I just added a new constructor that set the flag to a default state and everything came back to working.

I think this is all for right now,

SQL 2005 Diagrams not working on a restored backup from another machine

2007-05-05T08:32:00.000-07:00

I have been getting this error for a long time:
"Database diagram support objects cannot be installed because this database does not have a valid owner. To continue, first use the Files page of the Database Properties dialog box or the ALTER AUTHORIZATION statement to set the database owner to a valid login, then add the database diagram support objects."

Whenever I tried to get to a SQL diagram after having restored a database on another machine. Here are the steps to fix this:
1 - Right-Click on the database in question.
2 - Choose Properties
3 - On the "Select Page" option choose "File"
4 - Under "File" click on the "..." on the right side of the "Owner" field.
5 - On the "Select Database Owner" type "[sa]" on the "Enter object names to select" text area.
6 - Click OK on "Select Database Owner" window
7 - Click OK on "Database Properties"
8 - Enjoy the power to create and view Diagrams again.

Just a little tip to remind myself and others.

See ya,

Understanding the masks for ANSI

2006-10-30T08:19:00.000-08:00

There is a Mask on Table 0 (zero) which basically tells you what tables are supported on the device you are using. This Mask is normally composed by a collection of hex numbers, these numbers should be converted to binary and starting for the little-ending you count up for each byte. Example:

0x2F, 0xDC, 0xF1, 0xC0, 0x03, 0x0F
2F - 00101111
DC - 11011100
F1 - 11110001
C0 - 11000000
03 - 00000011
0F - 00001111
Now convert and count the tables:
0 07
0 06
1 05
0 04
1 03
1 02
1 01
1 00

1 15
1 14
0 13
1 12
1 11
1 10
0 09
0 08

1 23
1 22
1 21
1 20
0 19

1 32

0 47
0 46
0 45
0 44
1 43
1 42
1 41
1 40

Whatever tables which has a '1' next to it is supported on the device.

When IPAddress.Parse (C# .Net 2.0) does not behave as expected.

2006-10-10T07:32:00.000-07:00

Well if I send (string)”001.000.016.093” I was getting an exception, basically the IP address was not formatted correctly. I was not sure what that meant, since by all IP address standards that looks fine. It turns out that when you insert a “0” (zero) on front of a string representation of an IP address you are asking the system to convert the number to octal. This would explain the exception since 093 is not a valid octal number. If you were to type (string)(0377.0377.0377.0377) it would return you 255.255.255.255.

This finding is very funny and by funny I mean horrible, I am sure octal transformation had a great use somewhere, but for my application I will have to remove all the leading zeros before making this an IP address.

I think this is all for right now.

Not what I expected from Guid.ToByteArray() .Net

2006-10-04T12:43:00.000-07:00

An Guid is a 16 byte number, therefore when I got a return from ToByteArray I was expecting just that a normal 16 byte number, the problem I did not expect is that they are not in the same order you find it in the String representation of the same guid.

My input was

01020304-0506-0708-0900-000000000000

And instead of getting a byte array like this

1,2,3,4,5,6,7,8,9,0,0,0,0,0,0,0

I got

4,3,2,1,6,5,8,7,9,0,0,0,0,0,0,0

What the hell is that? So I sat down and mapped the thing and assuming this positions on the guid:

00000000-0011-1111-1111-222222222233
01234567-8901-2345-6789-012345678901

The map for the byte array is

0000|1111|2222|3333|4444|5555|6666|7777|8888|9999|0000|1111|2222|3333|4444|5555
0607|0405|0203|0001|1011|0809|1415|1213|1617|1819|2021|2223|2425|2627|2829|3031

To understand this weird notation it is basically on Guid position 12 (read vertically) you can find position 12 on the byte array to be the start of the 7th byte.

Well I hope this helps.

See ya,

Struct vs. Classes when using as members of a List

2006-09-29T08:44:00.000-07:00

I was trying to create a list of Struct items, and everything was going great, but when I tried to modify the items in my structure using a foreach loop it would not allow me. As it turns out the items in the List were protected. I could read them, but not modify them. I am not sure why that is. Perhaps it is the fact that Structures are in the Stack and are value types. I am not sure.

Here is the example of the code I was having problem. The VS2005 compiler was pointing to the “myStruct.A = 0;” under the “ZeroItOut” method and telling me “
Cannot modify members of 'myStruct' because it is a 'foreach iteration variable.”

using System;
using System.Collections.Generic;
using System.Text;

namespace EventSandBox
{
struct MyStructure
{
public int A;

}

class StructureForEachLoops
{
List MyStructureList;

public StructureForEachLoops()
{
MyStructureList = new List();
}

public void FillItUp()
{
for( int i = 0; i < 10; i++ )
{
/// create the item to be inserted into the list
MyStructure item;
item.A = i;

/// insert the item into the list
MyStructureList.Add(item);
}
}

public void ZeroItOut()
{
/// lets change the items
foreach (MyStructure myStruct in MyStructureList)
{
myStruct.A = 0;
}
}
}
}

Then I just change the word “struct” to “class” and things just worked. I also had to add the constructor before I could assign a value to item MyStructure type. This might again be because classes are loaded into the heap and can be modified. I am not sure.

using System;
using System.Collections.Generic;
using System.Text;

namespace EventSandBox
{
class MyStructure
{
public int A;

}

class StructureForEachLoops
{
List MyStructureList;

public StructureForEachLoops()
{
MyStructureList = new List();
}

public void FillItUp()
{
for( int i = 0; i < 10; i++ )
{
/// create the item to be inserted into the list
MyStructure item = new MyStructure();
item.A = i;

/// insert the item into the list
MyStructureList.Add(item);
}
}

public void ZeroItOut()
{
/// lets change the items
foreach (MyStructure myStruct in MyStructureList)
{
myStruct.A = 0;
}
}
}
}

Finding MAX for enumeration

2006-09-29T06:48:00.000-07:00

I wondered. How can I figure out how many items there are on a enumeration on .Net? Sometimes I had to go through enumerations to figure out the correct, item, but I could never find a way to do it, well no anymore.

using System;
using System.Collections.Generic;
using System.Text;

namespace EventSandBox
{
///

/// This is a simple enumeration
///

enum MyEnumeration
{
one,
two,
three
}

class Tools
{
static void Main(string[] args)
{
/// this item will return us the total number of enumerations
int numberOfEnumerations = 0;
/// we need this to be or rolling enumeration
MyEnumeration myEnumerationInstance = (MyEnumeration)numberOfEnumerations;

while (true)
{
/// if these two are the same it means the enumeration hit an end
/// because it did not return a text but instead the integer representation
/// and those two will be the same.
/// WARNING: This system will not work if you have a gab in your enumeration
if (myEnumerationInstance.ToString() == numberOfEnumerations.ToString())
{
break;
}

/// go to the next enumeration number
numberOfEnumerations++;
myEnumerationInstance = (MyEnumeration)numberOfEnumerations;
}

Console.WriteLine("There are " + numberOfEnumerations.ToString() + " items on MyEnumeration");

Console.Read();
}
}
}

I hope this helps out.

Assembly reference missing? No, I have that reference.

2006-07-19T06:56:00.000-07:00

I was getting the stupid error on Visual Studio 2005:
Error 4 - The type or namespace name does not exist in the namespace (are you missing an assembly reference?)
Well I was not missing an assembly reference, actually using intellisense it would show me the assembly name, so I was trying to figure out what was going on. I finally hit me. I had used Ultra Edit to replace some assembly names in some of my files, so the only thing I had to do was Right-Click on the solution name inside the “Solution Explorer” and ask to “Clean Solution” and “Rebuild Solution.” Done No more errors. I think Ultra Edit modified things that VS2005 was not aware, so with the Clean and Rebuild it forced VS2005 to read all the files again.
