C++ Project port from VS2003 to 2008

Question

Hi there,

i´ve got a problem porting a C++ MFC Project from Visual Studio 2003 to VS 2008. There is a problem creating Dialogs, that Ressources are in different Projects of the Solution.

The Project with the Main Frame starts a thread, that creates a little Splash Window. Another Project contains the code and the ressource to create the splash window Dialog. The Projects are linked through the variable gl_pGlobal. The gl_pGlobal Variable is created like this:

extern IPOLGlobal* gl_pGlobal;

/*! \def __InitPOLGlobalSystem()
    \brief Initialisieren das globalen System
*/
#define __InitPOLGlobalSystem()\
    IPOLGlobal* gl_pGlobal=NULL; \
    extern "C" __declspec(dllexport)void InitPOLLibrary(IPOLGlobal* pGlobalEx){ \
        gl_pGlobal=pGlobalEx; \
    } 

The IPOLGlobal is an interface where the CPOLGlobal class derives from. The CPOLGlobal class contains the Function that starts a thread. In the Project with the Main Frame, the gl_pGlobal is used to call the Function that starts a Thread:

gl_pGlobal->ViewBanner();

This is a part of the CPOLGlobas class (second Project), where the function is implemented.

...    
CPOLBannerThread* gl_pBannerThread=NULL;

void CPOLGlobal::ViewBanner()
{
            m_bHaveMoreThreads=TRUE;
            gl_pBannerThread = (CPOLBannerThread*)AfxBeginThread(RUNTIME_CLASS(CPOLBannerThread),THREAD_PRIORITY_NORMAL, 0, CREATE_SUSPENDED,NULL);
            gl_pBannerThread->m_bAutoDelete = TRUE;
            gl_pBannerThread->ResumeThread();
        }

..

The CPOLBannerThread class contains the Functions to start the thread and create the splash window, where m_bannerWnd the Dialog is.

...

BOOL CPOLBannerThread::InitInstance()
    {
        m_bannerWnd.Show();
        m_bannerWnd.m_ctrlEdit.SetWindowText(_T("Try to start ..."));
        return TRUE;
    }

void CPOLBannerDlg::Show(){
        AFX_MANAGE_STATE(AfxGetStaticModuleState());

        CWnd* wnd=CWnd::GetDesktopWindow();
        CDialog::Create(IDD_DIALOG_BANNER, wnd);

        ShowWindow(SW_SHOW);
        UpdateWindow();
    }

...

The CDialog::Create(IDD_DIALOG_BANNER, wnd); call crashes the Thread. This code worked when created with VS 2003, now in VS 2008 it crashed. Can you say what is wrong?

This is the stack Trace:

The Exception is invalid argument. In the Function ENSURE(this != NULL); crashes because this in NULL.

BOOL CObject::IsKindOf(const CRuntimeClass* pClass) const
{
    ENSURE(this != NULL);
    // it better be in valid memory, at least for CObject size
    ASSERT(AfxIsValidAddress(this, sizeof(CObject)));

    // simple SI case
    CRuntimeClass* pClassThis = GetRuntimeClass();

    ENSURE(pClassThis);
    return pClassThis->IsDerivedFrom(pClass);
}
