What's the problem? Insert control using Component Gallery. Two files will be added to your project as well as control's toolbar button to resource toolbar. One file is wrapper class header file and another file is wrapper class source file. Then you can compile and build your project

You seem not to include ActiveX controls support when you used AppWizard to generate the project. Check stdafx.h, it should look like the following,

...
#define VC_EXTRALEAN            // Exclude rarely-used stuff from Windows headers

#include <afxwin.h>         // MFC core and standard components
#include <afxext.h>         // MFC extensions
#include <afxdisp.h>        // MFC OLE automation classes
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h>                  // MFC support for Windows Common Controls
#endif // _AFX_NO_AFXCMN_SUPPORT
...

#include <afxdisp.h> might not be there in your stdafx.h.

And, check your cpp that contains the application class. In the InitInstance(), there should be

AfxEnableControlContainer();
