Gilciel,

Try using bitor(m.test_pid, 0) to cast the result properly for comparison with a known PID, as in the following snippet:

STORE 0 TO ProcId, ThreadId	&& initialize return variables
ThreadId = GetWindowThreadProcessId(m.nexthwnd, @ProcId)	&& get PID & TID
if bitor(m.procid, 0) = ;
  bitor(m.lookforpid, 0)	&& window belongs to known PID
    newhwnd = m.nexthwnd	&& found the new HWND for given PID
    exit			&& done with loop
endif
