Hi Gambit,

I'm not sure, is these any bugs?
Somehow, the STARTUPINFO is useless in CreateProcess to launch the 
NotePad.exe.

Before that I did the samething like your method, and I try again with your 
code, same
thing happended, the window did not place to the correct place, instead in 
start at the
previous location, any ideal what could the problem,

Regards,
KL Chin
