An activeX control on a simple MFC application works in VC++2008, but not in VC++ 2010

Question

I had a simple dialog based MFC application. The dialog holds a crystal report viewer control. It works fine in VC++ 2008. After converted to VC++ 2010, it doesn't work anymore: DoModal() as shown below failed.

    CCrystal_ReportDlg dlg;
    m_pMainWnd = &dlg;
    int nResponse = dlg.DoModal();

The error message is:

Program: ... File: f\dd\vctools\vc7libs\ship\altmfc\src\mfc\occcont.cpp Line:925.

Debugged into the codes, the error is from calling (in dlgcore.cpp)     

hWnd = ::CreateDialogIndirect(hInst, lpDialogTemplate,
            pParentWnd->GetSafeHwnd(), AfxDlgProc);

VC++ 2010 doesn't work for this CrViewer and another ActiveX controls. They works fine in VC++ 2008.

Thanks for any possible helps.

Answer 1

Debug again and execute the line after CreateDialogIndirect that calls GetLastError (or just type “@err,hr” into Watch window. This will give an error code. Which code do you see?

Answer 2

 The mfc codes (dlgcore.cpp) that generate the error:

  hWnd = ::CreateDialogIndirect(hInst, lpDialogTemplate,
		pParentWnd->GetSafeHwnd(), AfxDlgProc);
#ifdef _DEBUG
  dwError = ::GetLastError();
#endif

GetLastError() returned 0.

The cause of the problem is due to the following activeX control template in the .rc file, for which VC++ 2010 gives error in DoModal(), while VC++ 2008 works fine.

IDD_CRYSTAL_REPORT_DIALOG DLGINIT
BEGIN
    IDC_ACTIVEXREPORTVIEWER1, 0x376, 128, 0
0x0000, 0x0000, 0x0710, 0x0000, 0x6a8f, 0x0000, 0x5a05, 0x0000, 0x000b, 
0x0000, 0x000b, 0xffff, 0x000b, 0x0000, 0x000b, 0xffff, 0x000b, 0x0000, 
0x000b, 0xffff, 0x000b, 0xffff, 0x000b, 0x0000, 0x000b, 0x0000, 0x000b, 
0xffff, 0x000b, 0xffff, 0x000b, 0xffff, 0x000b, 0x0000, 0x000b, 0x0000, 
0x000b, 0xffff, 0x000b, 0xffff, 0x000b, 0xffff, 0x000b, 0xffff, 0x0008, 
0x0000, 0x0000, 0x000b, 0x0000, 0x000b, 0xffff, 0x000b, 0x0000, 0x000b, 
0x0000, 0x000b, 0x0000, 0x000b, 0xffff, 0x0013, 0x0409, 0x0000, 0x000b, 
0x0000, 
    0
END

No sure anything wrong of this control template which was generated from the rc editor.

Found the solution:

Under the Project Configuration Properties go to Linker -> Advanced and set the 'Data Execution Prevention' property to No.
