Strange issue with the VS2010 debugger

Question

Hi,

I've installed visual studio 2010.

When unhandled exception is thrown, nothing happen...

I created new windows form application and wrote 1 line in the form_load function:

    private void Form1_Load(object sender, EventArgs e)
    {
        throw new Exception("");
    }

And still nothing happen. The only thing I can see is the "A first chance exception of type 'System.Exception' occurred in WindowsFormsApplication1.exe" in the output window.

It looks like this error was catch but I dont know how... (This line is the only line I wrote in this project).

How can I solve this issue?

Thanks!

Answer 1

Are you referring to the behaviour where the debugger breaks on the exception? If so, this is configurable and off by default. If memory serves: Debug -> Exceptions... -> Common Language Runtime Exceptions, check "Thrown".

Answer 2

You could also register your program for the UnhandledExceptionEvent. To do so write the following into your Program.cs before calling Application.Run(new MyForm()):
AppDomain.CurrentDomain.UnhandledException += OnCurrentDomainUnhandledException;

Then declare your event catcher like private static void OnCurrentDomainUnhandledException(object sender, UnhandledExceptionEventArgs e) and do what ever you want to do with that exception.
