Another good way to trace your program is to write some code containing the
following procedures:

TrcStart(HWND hwnd);
TrcStop(HWND hwnd);
TrcWrite(HWND hwnd,PCHAR fmt,...);

TrcStart checks a list of active trace windows, and creates a NEW window
containing a listbox if the window handle does not already have a trace window
associated with it.

TrcStop checks the list of active trace windows, and WinDestroyWindow()s the
trace window associated with the specified window handle.

TrcWrite uses vsprintf() to format the string and sends a LM_INSERTITEM to
the trace window's listbox to write the string out.

If you create your listbox with LS_HORZSCROLL, then you have a full-fledged
tracer that can be used with any PM program.
