I am using the Unicode Debug build of version 2.60 in an MFC exe application, and the Unicode Debug RDE build in an MFC regular dll.

I have written a class that extends CExtGridCellString. The new class is part of an MFC regular dll. I have used CExt_ProfUIS_ModuleState::InitExtension( AfxGetStaticModuleState() ); in the InitInstance method and called AFX_MANAGE_STATE. The MFC exe that uses the new MFC DLL project compiles and links fine. However, when I run the application I am receiving an assertion at line 41530 in ExtGridCell.cpp. This is the assertion that fails:

ASSERT( pInitRTC->IsDerivedFrom(RUNTIME_CLASS(CExtGridCell)) );

I’m not sure what I am missing. Is there a sample MFC dll project that uses Prof UI that I could get so that I can make sure that all of my settings are OK?

Thanks,

Dave

I switched the project to an MFC extension dll, and it works fine. This will work for us, since the dll will only be included in an MFC application.

I think that it would still be a good idea to have a sample project that uses Prof UIS in a regular MFC dll for future reference.

Please ensure your grid cell class has the following lines in scope of class declaration:

    DECLARE_SERIAL( CYourGridCell );
    IMPLEMENT_ExtGridCell_Clone( CYourGridCell, CExtGridCellString );

and the following line in the .cpp file:

  IMPLEMENT_SERIAL( CYourGridCell, CExtGridCellString, VERSIONABLE_SCHEMA|1 );

The last line should be placed at the top of the source file before the DEBUG_NEW symbol is defined.

Alternatively, the assertion described in your message can occur if you forgot to manage MFC state at the beginning of the exported method or function.

Thanks for your reply. I had already included the code that you indicated in your response. I had put the AFX_MANAGE_STATE macro in all public methods of the class. I used _declspec(dllexport) on the class.

The assertion happens on the following line in the MFC exe application when trying to add a timeline cell to the grid:

CExtGridCellTimeLine * pCellTimeLine =
            STATIC_DOWNCAST(
                CExtGridCellTimeLine,
                m_wndGrid.GridCellGet(
                    GRID_COL_TIMELINE,
                    rowNo,
                    0,
                    0,
                    RUNTIME_CLASS(CExtGridCellTimeLine)
                    )
                );

I sent the MFC dll project to the technical support email address.
