I've created an activeX that responds to mosue events by using the class wizard and adding message maps for the WM_LBUTTONDOWN an WM_LBUTTONUP Messages. When I test the ActiveX in the ActiveX Control Test Container, the mouse events work. When I drop the ActiveX control on a Dialog in another project, the events do not work. Can someone please shed some light on what I am missing to get my mouse events working properly. Thanks!
