Hello,
I'm a student and not very proffessional in programming, but i want to use the OnTimer function. This is working very well in an other class, but in this not. With the debugger i check and the function OnTimer is never activated. But the SetTimer is done (also checked with the debugger)

Maybe you're expert and see the problem in one eye?
Thanks for have a look, Bart

This code is only a test-part, because the problem is around the timer i put away the original code and create a some test code.
I'm using C++ / MFC
