As MSDN's docs say, Thread.Abort() throws an exception in the corresponding thread:
"Raises a ThreadAbortException in the thread on which it is invoked, to begin the process of terminating the thread. Calling this method usually terminates the thread."
Does it mean that I have to catch the exception, and perform an aborting routine?
Or perhaps I should leave the exception, and expect it to just terminate?
Thanks,
Shy.

Not handling it will result in an unhandled exception in your application which might result in a crash (or that nasty dialog coming from .Net).
Catching it an gracefully clearing up resources/doing cleanups is the way to go.

You can catch the ThreadAbortException in the thread if you want to make it aware of that it is being aborted.
There are three ways of keeping the thread from being aborted:
:: Go into an eternal loop after catching the exception to keep from exiting the catch block, as exiting the catch block automatically raises the exception again.
:: Go into an eternal loop in a finally block, as all pending finally blocks are executed before the thread is killed.
:: Call Thread.ResetAbort after catching the exception to cancel the abort. This is of course the preferred method if the intention really is to keep the thread alive.
In any other case, the thread will be aborted.

Hello Folks,
I am wondering if I can start a second application from a first one, something like shell execute but on Win CE.
I use C# on Win CE and try to write something like a bootloader. The bootloader starts and checks a few things and then should launch another application.
Does somebody know how to d that?
Thanks a lot,
Marco

You can use the native calls ShellExecute or CreateProcess by using dllimport
In the class you wish to start another app use the following namespace
using System.Runtime.InteropServices;
then define from which dll to get the function and the function name with dllimport and on the immediately next line define the function with all the parameters
<br />
[DLLImport("Coredll.dll", EntryPoint="TheFunctin")]<br />
public static extern void TheFunction(... all your params...);<br />
In the above example replace the TheFunctin with the actuall function name you wish to import (in your case CreateProcess or ShellExecute, and replace the ...all your params... part with correct parameters -> depends on which function you^ll use...
I think CreateProcess is in the Coredll.dll lib and ShellExecute is in the CeShell.dll, but you`ll have to doublecheck that.
Friendly Regards,
Davy

Davy,
thanks a lot for your help!
I'm not quite familiar with the dll-import but I guess I'll figure that out.
Best regards,

Hi,
I've created a control which has a string field, accessed through a bindable property.
However, when the control is in a form, and the bindingsource has a null value in the binded property, the value of the string is never updated.
I've tried using the advanced databinding properties to set an empty string when the incoming value is null, but no luck so far.
Any ideas? thanks in advance

I hane an application where one of my dialogs is created when the program starts. I like to call Form.Show() and Form.Hide() to show and hide the form.
When the user presses the system-X button the form is per default disposed. How do I prevent that I just want a Form.Hide() when the user does that so that I can call Form.Show() again without making a new instance of it.

Handle the Closing event on the form and cancel the operation (see the event arguments, e). You can then hide the form instead.

Hi
Can any one tell me how to check for the end of row condition in the data base table using c#.
Is there any function like Movenext() to fetch next row values from the table?

It all depends on how you are getting the data out of the database in the first place.
It sounds like you are using a DataReader. The DataReader.Read() pulls in the next row from the database. It returns true if a row was fetched or false if there are no more rows.
Does this help?

Use :
System.Resources.ResourceManager resources = new System.Resources.ResourceManager(typeof(Form1));
this.textbox.Text = resources.GetString("Key1");
In your resource file, you must add -> Key1 = HelloWorld (for example).

I added first line of code to form1.designer.cs and have the text control retrieve the string.
but when debugging, the string doesn't show on the form designer.
What am i missing?
