Hello,

I have decided to start using certain .Net Framework classes in my C++ MFC applications, so this requires complilation of the app using the /clr option. The stdafx.h file #includes the XTreme Toolkit Pro libraries.

The application uses the Codejock commandbars and when the app is run it returns a .Net "System.NullReferenceException" exception when CXTPCommandBars->SetMenu() is called in CMainFrame::OnCreate(). Here is the code in question:

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)

{

[...]

CXTPCommandBars* pCommandBars = GetCommandBars() ;

CXTPCommandBar* pMenuBar = pCommandBars->SetMenu ( _T("Menu Bar"), IDR_MAINFRAME ) ;

[...]

}

Stepping into the code using the debugger shows that, inside CXTPCommandBars::GetMenu(), the value of the parameter CString strName seems to be garbage characters rather than the supplied value (ie. _T("Menu Bar") ) . This garbage CString is then passed to CXTPMenuBar::SetTitle() which errors out further up the call stack in the ATL/MFC class CSimpleStringT class. I'm guessing the error is caused by the garbage CString passed into GetMenu().

When the app is not compiled with /clr, the code works as expected. Also note that the XTreme Toolkit Pro dlls are NOT compiled using /clr in either case.

Has anyone run into this problem before? And/or can someone help with this? Thanks.

So may be you need to compile dll WITH /clr ?
