I just added included Prof-UIS.h and now getting the above mentioned error message. Is CCommand a class used in Prof-uis?

Still getting:    error C2872: ’CCommand’ : ambiguous symbol

I tried another approach. I added a CCommand class to one of your sample projects

 class CCommand



    CCommand() {}

    ~CCommand() {}


static bool g_bSplashWndClassRegistered = false;


    CWnd * pWndParent,

    UINT nBitmapID


    : m_nMaxTextLines( -1 )

    , m_nLineHeight( -1 )

    , m_clrText( RGB(255,255,255) )

    , m_rcText( 0, 0, 0, 0 )


    CCommand c;

    VERIFY( RegisterSplashWndClass() );

    VERIFY( Create( pWndParent, nBitmapID ) );


Got the error message:

--------------------Configuration: ProfUIS_Controls - Win32 Unicode Debug--------------------



C:\Program Files\FOSS Software Inc\Prof-UIS trial\Samples\ProfUIS_Controls\MainDlg.cpp(47) : error C2872: ’CCommand’ : ambiguous symbol

The CCommand class is present in the OLE DB template library:

Prof-UIS has no classes with such name. If you are using Visual C++ 6.0 and some newer Platform SDK is installed, then the OLE DB templates are available and can be included into your project via other ATL/MFC header files.

In any case, only Microsoft allows itself to call classes using such simple names like CCommand. You should use something like CMyCommand.

OK, I’ll try that - thanks for info

No, there is no such class in Prof-UIS. Besides, we have just compiled Prof-UIS with all the Visual C++ versions starting from 6.0 and up to 2010 and we have not encountered this conflict. Please check the include folders list in your Visual Studio settings. The standard includes must be at the top. Any newer Platform SDK and/or DirectX SDK must be at the bottom.
