How to invoke methods of contained ActiveX control from ATL Composite Control
You can always QI it for its dual interface... #import is of immense
help here - assign the interface you got from GetDlgControl to
an instance of the wrapper class generated by #import. This means
you need exception handling of course (thus the CRT, so remove
_ATL_MIN_CRT from the release builds)...
