OLE Automation Sample


The DispDemo sample is an OLE Automation controller. DispDemo drives the 
two polygon servers which are also provided as samples.

The interesting part of DispDemo is in the remote polygon class. The remote 
polygon class was constructed so that the IDispatch members could be 
accessed conveniently from C++. The remote polygon class does this by 
transforming the C++ calls into IDispatch calls. The code that calls these 
routines has no idea that it is going through IDispatch.
