Exception in Application.Run()

[Guest]

Hi - I am getting a Null Reference Exception that is being thrown from
Application.Run() method. This ocurrs after multiple events are raised which
update a few user controls inside the Main Form.

i cannot seem to isolate the exception any further than the Run method()
even though I have placed other Excep handlers just about everywhere. Is
there any technique for investigating an exception of this kind? The full
exception text is below:

Caught Main() Exception: Message: Object reference not set to an instance of
an object.

Hi BillyMac

You could try to handle the ThreadException event.

Simply put
Application.ThreadException += new
System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
before Application.Run(...);

and define the Handler:

static void Application_ThreadException(object sender,
System.Threading.ThreadExceptionEventArgs e)
{
// e.Exception is the exception.
......
}
