    Abnormal application termination

    Hello all of you!

    I have a strange problem and I need help to solve it.

    I have a windows application written in C# that sporadically terminates, no exceptions, no error codes, no messages at all. The application starts a new thread which sends information to the windows form via events. The thread uses USB-connected printers to print small paper-labels and a USB-CAN interface.

    Is it a thread related error? Deadlock? Stack overflow?

    Is it caused by a collision in the USB-interface?

    Hopfully, Daniel Carlson

    1. Check the Event Viewer Application Log, sometimes .Net applications will toss an error message there.
    2. Do you have Try/Catch/Finally blocks around the code?
    3. Can you run the application from within the IDE and get the same issue?
    4. Have you tried running in Debug and/or Trace mode to catch additional information?

    Try adding an application-level exception handler.
    Very easy to do in .Net
    See Application.ThreadExceptionHandler

    1. No information here...
    2. Yes, I have a try/catch-block around the thread code block. No exceptions can be thrown from within the thread.
    3. Yes, sometimes I have noticed the same problem when runnig in the IDE.
    4. No more information when running in debug and/or by using trace...

    Thank you for this replay. As I can se no application-level exceptions are thrown.
