Question

To lean about interfaces, I’m trying to write a test project to implement the IDispatch interface.
So far I’ve:

• created an MFC dll project in visual studio 2010

• written the following IDL

  [ uuid(68B0FAE7-3828-415D-94B0-720A007311FF), version(1.0) ]
  library Test
  {
  importlib("stdole32.tlb");
  importlib("stdole2.tlb");
  [ 
      uuid(DD35D282-ABEF-4411-B3D1-B4FD848516A5)  
  ]
  
  interface _Test : IDispatch
  {
  
  };
  };
  

Created a C header file called Test.h but I’m wandering how I declare this to be linked to the IDL. Any help or hello world tutorials would be great. Thanks

Answer 1

You can you the

• midl compiler

  It is capable of generating header/sources in c (or C++? don’t remember), but most importantly it will get you a typelibrary (tlb) file

• #import directive

  Will generate c++ definitions for the typelibrary contents.
