Sudden Application Close

[Diogo Alves - Software Developer]

hi, I'm using the vs2003...

I don't know what is going on... everytime my application connects to a
device that I have, i do the connection and disconnection sucessfully but
after a while, and only sometimes (it's a random error) the application
closes... does not give any error and there isn't any exception, nothing... I
can't figure how to trace what is going on... there is nothing wrong?

Do you know any way to get around it?

Diogo,

Are you doing anything on a thread perhaps? If so, can you wrap that
code in a try/catch block and see what it is? If there is an error on the
UI thread, then you should definitely see a message, but not necessarily on
another thread.

Attach the below events in your main.

AppDomain.CurrentDomain.UnhandledException+=new
UnhandledExceptionEventHandler(CurrentDomain_Unhan dledException);
Application.ThreadException+=new
ThreadExceptionEventHandler(Application_ThreadExce ption);

Examine if you get any errors here... using the EventArgs..

Forgot this .. you have to add the events before the Application.Run, in
your main.. and declare the events as static... So you catch globally any
exception thrown...Remember this wont catch exception thrown from secondary
threads....

What you use Application.ThreadException for ?

IIRC it does gets an notification when a thread throw an exception, no
matter what thread.
