Description: There are many owner-draw button written using C++ and the MFC classes. There a lso many ActiveX controls, mostly written in Visual Basic. While with C++ you can easily use both the MFC and the OCX controls, with Visual Basic you need to convert the MFC objects to an activex control. Unluckily, the class wizard doesn t cover all the messages and the events sent to an ActiveX control, and some messages are different, so most of the magic must be hand written. Because sometimes a piece of code is more clear than the article itself, I included the porting of CxShadeButton to an ActiveX control, but it s just an example, in the article I will speak about a generic AxButtonCtrl.
