ApplicationException unhandled by user code

[bg_ie@yahoo.com]

Hi,

I have the following Program.cs -

namespace TestFrameworkAp plication
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.Ena bleVisualStyles ();
Application.Set CompatibleTextR enderingDefault (false);
Application.Thr eadException += new
ThreadException EventHandler(ne w
ThreadException Handler().Appli cationThreadExc eption);
Application.Run (new FormMain());
}

/// <summary>
/// Handles any thread exceptions
/// </summary>
public class ThreadException Handler
{
public void ApplicationThre adException(obj ect sender,
ThreadException EventArgs e)
{
MessageBox.Show (e.Exception.Me ssage, "An exception
occurred:", MessageBoxButto ns.OK, MessageBoxIcon. Error);
Application.Exi t();
}
}
}
}

In my Form, I attempt the following -

private void button1_Click(o bject sender, EventArgs e)
{
ThrowException( );
}

private void ThrowException( )
{
throw new ApplicationExce ption("Monkey exception");
}

But when I click on the corresponding button, I keep getting the
message "ApplicationExc eption unhandled by user code" from the
debugger. But once I continue the debugger, the message box pops up
with the error. What is the debugger warning me about and can I switch
off this message if I am not actually doing anything incorrect?

Thanks for your help,

Barry.

RE: ApplicationExce ption unhandled by user code

It seems to me that you are throwing an ApplicationExce ption, which
apparently is not the same exception type that you have code to handle for
(ThreadExceptio n).

RE: ApplicationExce ption unhandled by user code

Try this:

Go to VS 2005 menu Tools | Options and then Debugging/General. Uncheck
'Enable Just my Code'.

That worked, thanks. But why did it work?

RE: ApplicationExce ption unhandled by user code

ThreadException event should occur on any unhandled exception in current
thread; example in MSDN throws ArgumentExcepti on as well.

Still I don't understand working with unhandled exceptions. In my
application I used Application.Thr eadException event to display dialog box
when unhandled exception occured and it worked... until non-catched exception
was thrown from Application.Idl e event handler. ThreadException event handler
was not called and standard .NET dialog box appeared advising to send report
to MS.

If I handle AppDomain.Curre ntDomain.Unhand ledException, this handler *is*
called when exception in Idle occurs. But it only informs about exception.
When my handler ends, standard .NET crash dialog box appears again.

The exception in Idle handler can also be caught by sorrounding
Application.Run with try-catch. But that would require some "goto" or "while"
to resume the application if I wish to continue after exception.

I cannot make head of it:)
