How to: Add MFC Support to Resource Script Files
Normally, when you build an MFC application for Windows using the MFC Application Wizard, the wizard generates a basic set of files (including a resource script (.rc) file) that contains the core features of the Microsoft Foundation classes (MFC). However, if you are editing an .rc file for a Windows application that is not based on MFC, the following features specific to the MFC framework are not available:
MFC code wizards (previously called "MFC ClassWizard")
Menu prompt strings
List contents for combo box controls
ActiveX control hosting
However, you can add MFC support to existing .rc files that do not have it.
To add MFC support to .rc files
Open the resource script file.
If your project doesn't already contain an .rc file, please see Creating a New Resource Script File.
In Resource View, highlight the resources folder (for example, MFC.rc).
In the Properties window, set the MFC Mode property to True.
In addition to setting this flag, the .rc file must be part of an MFC project. For example, just setting MFC Mode to True on an .rc file in a Win32 project won't give you any of the MFC features.
