Hi all
I have some problems to control the mouse wheel. Whats the code when the whell goes forward and backward ? I have only WM_MOUSEWHEEL (and WM_LBUTTONDOWN , WM_RBUTTONDOWN, etc.). Any one can help me ?
Thanks
Rui
The documentation is here (http://msdn2.microsoft.com/en-us/library/ms645617(VS.85).aspx). But I have the same problem - this message does not work as described, although it might be dependent on drivers and OS version.
Hi jj2007
Thank you so much ! It works fine. Now i know that when we move the mouse wheel the windows sends the message WM_MOUSEWHEEL and if the high-order word of wParam is positive
the wheel was rotated forward (UP), if negative, backward (DOWN).
Thanks !
