SYMPTOMS

The ATL COM AppWizard does not offer the option of MFC support for an .exe project. Adding an MFC class with ClassView or ClassWizard results in build errors.

RESOLUTION

To add minimal MFC support to an ATL COM AppWizard project, follow these steps:

1. Open the ATL project with Visual C++.
2. On the Project menu, click Settings.
3. Under the General tab, set the Microsoft Foundation Classes field to "Use MFC in a Shared DLL" or "Use MFC in a Static Library". Click OK.

4. Open the project StdAfx.h header file. Add the following line after "#define STRICT", then save and close the file:

         #include <afxdisp.h>
                           

5. Open the project .rc source file in text mode for editing:
   
   
   1. On the File menu, click Open.
   2. Highlight the <projectname>.rc file.
   3. Set the Open As field to "Text", then click Open.
   4. Click OK on any resulting message boxes.
6. Replace all occurrences of Winres.h with Afxres.h in the .rc file, then save and close the file.
7. Delete the <projectname>.clw file if it already exists.
8. Invoke ClassWizard by clicking ClassWizard on the View menu. Click Yes when prompted to rebuild the ClassWizard database, and then click OK on the next dialog box.

MFC class files added with ClassView or ClassWizard should now build without errors.

STATUS

This behavior is by design.

NOTE: In Visual C++ 6.0, another option exists. Create an MFC project first, and then click New ATL Object on the Insert menu. Click OK on the next dialog box to insert ATL support into the MFC project.

MORE INFORMATION

Steps to Reproduce Behavior

1. In Visual C++, create a new ATL COM AppWizard project.
2. In the wizard's Step 1, select either "Executable (EXE)" or "Service (EXE)".
   

NOTE: The "Support MFC" check box is disabled.

1. Finish the project. Click Finish, then click OK.
2. On the ClassView pane of the new project, right-click the project name. Select New Class from the menu.
3. Change Class Type to "MFC Class", give the class a name and a base class, then click OK.
4. Build the project.

RESULT: Build errors prevent the build step from completing successfully.
