Re: inheriting the VC++ template classes into C#.net

I didn't see any template<> in your code...

At any rate, this is a C++ class and cannot be accessed
directly in .NET. You need to wrap it in a C++/CLI
class first, or expose it via COM and COM Interop
(what Brian suggested). For the first approach (e.g. if
it's possible with MFC) you should ask in the C++/CLI
group:

microsoft.public.dotnet.languages.vc

For the second approach you can ask in the Interop group:

microsoft.public.dotnet.framework.interop

The C++ classes which I mentioned are classes which are derived from
MFC standard classes like CPropertyPage and CPropertySheet.

These template classes are simple MFC classes which are packaged as a
DLL. Since the Implementation part of this DLL is huge, I can't think
of rewriting the whole code in C#.

I have attached the the class template code snippet for your reference.
I need to inherit from this class, DTMPOPropertyPage in C#.

How can I achieve this?

class AFX_EXT_CLASS DTMPOPropertyPage : public CPropertyPage

{

// Construction

public:

     //DECLARE_DYNAMIC(DTMPOPropertyPage)

            DTMPOPropertyPage(FDTXmtrDoc *doc, UINT nIDTemplate = 0,
UINT nCaption = 0);

            ~DTMPOPropertyPage();

            //{{AFX_DATA(CXmtrPropertyPage)

                        // NOTE - ClassWizard will add data members
here.

                        // DO NOT EDIT what you see in these blocks
of generated code !

            //}}AFX_DATA

            // Attributes

public:

            // Access to determine if performing CANCEL processing.

            // Pages use this to avoid validation

            //BOOL InCancelProcessing ();

// Overrides

            // ClassWizard generate virtual function overrides

            //{{AFX_VIRTUAL(CXmtrPropertyPage)

            // Define a generic OnKillFocus handler for use by all
pages

            //afx_msg void OnKillFocus();

            virtual void DoDataExchange(CDataExchange* pDX); //
DDX/DDV support

            //}}AFX_VIRTUAL

            virtual BOOL OnInitDialog() { return
CPropertyPage::OnInitDialog(); }

            virtual BOOL OnSetActive() { UpdateData(FALSE); return
CPropertyPage::OnSetActive(); }

            //virtual BOOL OnKillActive();

            // access to BO parameters

            virtual void SetValues() = 0;

            virtual void UpdateDocument() = 0;

            // access to AppInfo

            FDTAppInfo *GetAppInfo();

// Implementation

protected:

            // Generated message map functions

            //{{AFX_MSG(CXmtrPropertyPage)

                        // NOTE: the ClassWizard will add member
functions here

            //}}AFX_MSG

    //afx_msg LRESULT OnCommandHelp(WPARAM, LPARAM lParam);

            //afx_msg LRESULT OnShiftF1Help(WPARAM, LPARAM lParam);

            //afx_msg void OnHelp( );

            afx_msg BOOL OnHelpInfo( HELPINFO* lpHelpInfo );

            //_DLLPROC DECLARE_MESSAGE_MAP()

            DTMPOPropertySheet *GetSheet();

            // pointer to document

            FDTXmtrDoc *mDoc;

private:

            void SetSheet( DTMPOPropertySheet *ps );

            friend class DTMPOPropertySheet;

            mDTMPOPropertyPage *m;

};
