OnMouseWheel event with MFC
I noticed that some touchpad drivers implement scrolling using the WM_VSCROLL message, however since the java AWT mouseWheelListener works, my recommendation is:
Open Spy ++ and check if WM_MOUSEWHEEL messages are being sent.
If messages are not published, the control may not have focus.
If messages are being sent, there may be a problem with how the control tries to receive the message. In this case, a message map can help us.
