WinForms app exit suddenly

[deerchao]

Hi, there.
I'm developing a WinForms application, and a user reported that it
will exit suddenly seconds after startup, every time. There isn't any
prompt at all, just like he killed the process from task manager. I
think I catched most of possible exceptions, and in case it's because
of an uncatched exception, there should be something like "Do you want
to send report to Microsoft" dialog.
In my app, I used Thread, FileSystemWatcher, WebClient, and gloabl
keyboard hook depends on user's setting. Is there any chance that
these components will cause this behaviour?
My app is developed on .Net 2.0, and my user is using Windows XP sp2
with .Net 3.0 installed.

Thanks!

Hello deerchao,

how do you handle unhandled exceptions?
do u use AppDomain.UnhandledException event?

Thanks, I'll try System.appdomain.UnhandledException. Currently I only
hooked System.Windows.Forms.Application.
ThreadException.
