You cannot. ActiveX Controls are true controls (with their own window and are self-redrawing). VFP "controls" are just drawed on the form by the VFP. When VFP draws its "control" over, ActiveX Control redraws itself and "clear" VFP drawing...

The only way I found is to put ActiveX Control into VFP Container class. When you resize container below the control's size, container will hide the rest of the control. On the place where ActiveX control is invisible VFP "controls" will be visible properly.
