Application.Exi t doesn't raise the OnClosing event???

[Ole]

The Application.Exi t (called from a worker thread) method doesn't cause the
OnClosing event handler to be run - is that a default behaviour??? If so -
what should I do to properly close all threads etc.

Thanks
Ole

As a general rule, wouldn't it be better to have the worker thread
alert the parent process that a close application has been requested?

The parent process could take care of cleaning up after all the
threads, as it's the only process that would properly know about all
the worker threads.

Just a thought...

This is the default behavior:

You can hook the Application.App licationExit event or call the Close()
method of your main form. This has the advantage that all expected
events are raised

If you decide to call the close method, remember to invoke the call when
you are not in the Gui Thread:

private delegate void NullaryFunction ();
private void CloseForm()
{
Debug.Assert(ma inForm != null && mainForm.IsHand leCreated);
if (mainForm.Invok eRequired)
mainForm.BeginI nvoke(new NullaryFunction (mainForm.Close ));
else
mainForm.Close( );
}

Thanks a lot! Btw - do you have an idea of how to close a similar
windowsless apllication from code?

Best regards,
Ole

Not a general one, because that really depends on the application type.

Cheers,
