Augmented codes of using media play control in MFC

Using media player control in MFC is not as easy as dragging in a button control. Usually there are some high frequent errors such as ‘cannot convert from LPDISPATCH to CWMPMedia/CWMPControls’, and the worse thing is that even Google is not able to provide proper solutions to address these errors except dozens of posts raising similar problems waiting for somebody to provide positive solutions.

I have experienced that and that was awful. Therefore i decide to share these solutions by providing functional codes as below. The solution is easy, after adding new media player relevant classes then, using codes below to replace those generated automatically by system. The key part of the change is from ‘public:CWND’ to ‘public:COleDispatchDriver’.
