问题
I am trying to use the COM system for VCProjectEngine. It is pretty simple to use in C# but I am hitting a wall in native C++.
I am using the COM system and so far I was able to get a pointer to the VCProjectEngine interface using the CoCreateInstance function.
But now what should I do with this interface? I would like to access the VCProject interface to be able to add files to the project. I tried to go with LoadProject or CreateProject but it takes a IDispatch parameter not a VCProject one.
Can someone help me with that?
回答1:
Calling COM interfaces from C++ can be done in a number of different ways:
- "low-level" COM calls using CoCreateInstance and the IUnkown interface
- ATL (Active-X Template Library) which provides a number of smart pointers and utility functions to make the job a lot easier. Use in conjuction with #import to generate wrapper classes for you.
- For Windows Store Apps you should use C++/Cx or WRL (Windows Runtime C++ Template Library)
There are many good tutorials and code samples on MSDN.
