>The problem is that the MOUSE CLICK is sent to the hWnd of the form, not the control it's positioned over; you should either get the hWnd of the ActiveX control and use PostMesage() to pass a WM_MOUSEDOWN and WM_MOUSEUP to the hWnd of the ActiveX control, or simply invoke the Click() method of the control on the form.

I see...makes sense. Could you elaborate on how to implement PostMessage() WM_MOUSEDOWN and WM_MOUSEUP and how to access the "hWnd" of the ActiveX control?

Thanks,
