CBaseBasicVideo Class
.gif)
This class handles the IDispatch component of the IBasicVideo interface and leaves the properties and methods as a pure virtual function.
The IDispatch::GetIDsOfNames, IDispatch::GetTypeInfo, IDispatch::GetTypeInfoCount, and IDispatch::Invoke methods are standard implementations of the IDispatch interface using the CBaseDispatch class (and a type library) to parse the commands and pass them to the pure virtual methods of the IBasicVideo interface.
