Strange because I WAS able to read the button caption of a Afx window class using GetText. ...And clicking the control twice or more didn't help neither.

So if there's no other solution I have no choice but to stick with those mouse_event MOUSEEVENTF_MOVE & CLICK methods. Sure it would have been better to use SendMessage/BM_CLICK and free my mouse mouvements. In that matter, would there be any api to "fake/simulate" a click to X,Y coords without affecting my mouse?
