It would be nice to immediately clean up the icons from the system tray
once those programs have stopped.

Should I just pass 0 to those functions or bogus HWNDs... or do

That's not C++, but C, but in both NULL can be used for both: pointers
and ordinals. In Pascal HWND is an ordinal and there the correct

need to do this for the first param as well.
Just goes
