COMMAP Sample: Demonstrates COM Interface Map Entry Macros with Compiler COM Support
This basic sample shows how different COM interface map entry macros are used. This sample uses the smart pointer mechanism (_com_ptr_t) of Visual C++ native compiler COM support. The #import mechanism is used instead of the MIDL-generated .h and .c files to provide marshaling information.

This sample code is intended to illustrate a concept, and it shows only the code that is relevant to that concept. It may not meet the security requirements for a specific environment, and it should not be used exactly as shown. We recommend that you add security and error-handling code to make your projects more secure and robust. Microsoft provides this sample code "AS IS" with no warranties. |
