Application unhandled exception

[Shehab Kamal]

In Main I register ThreadException to handle unhandled exceptions
Application.Thr eadException += new
ThreadException EventHandler(Ap p_ThreadExcepti on);
The method will show a MessageBox or a Form instead of .NET 2 default
dialog. However I don't get the code work. What am I missing?

One silly question. Can I post .NET 2 questions here or should I post to
msdn2?

Thanks in advance,
Shehab.

I don't know. You need to run outside the debugger for one thing,
because under the debugger VS hacks your application message loop and
inserts its own code into the call stack - highly frustrating, I
personally find. Also, it will only catch exceptions that are invoked on
the GUI thread via message loop dispatching - things like painting,
click events, etc.

This console application works well for me:

---8<---
using System;
using System.Windows. Forms;

static class App
{
static void Main()
{
Application.Thr eadException += delegate
{
Console.WriteLi ne("Caught!");
};

Form form = new Form();
form.Click += delegate
{
throw new Exception();
};

Application.Run (form);
}
}

..NET 2 is .NET as well.

Hello Shehab,

Add event handler for all threads in the appdomain

appdomain.Curre ntDomain.Unhand ledException += new UnhandledExcept ionEventHandler (CurrentDomain_ UnhandledExcept ion);


SKIn Main I register ThreadException to handle unhandled exceptions

Re: Application unhandled exception

The 2 answers complete each other.
I have thrown an excpetion after clicking a button and it was handled by App
not AppDomain.
I have thrown an exception from the constructor and it was handled by the
AppDomain not App. However the "sorry for inconvenience" message box appears,
can I get rid of it or it is built in windows?

Thanks for the 2 answers.
