Load Resource from other DLL

Hi there,

i had a Projekt that worked with VS 2003. Then i ported it with the help of the Studio to 2008. Now the following class crashes when i start the Application in Debug mode. The crash occurs in the Function calling CDialog::Create(IDD_DIALOG_BANNER, wnd);

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

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

        ShowWindow(SW_SHOW);
        UpdateWindow();
    }

Here is the class, that is in another DLL of the Solution. The class will be called as a thread from the MFC Project of the Solution.

#include "stdafx.h"
#include "../../include/utility/POLBanner.h"
#include "../../resource.h"

#ifdef _DEBUG 
#define new DEBUG_NEW 
#undef THIS_FILE 
static char THIS_FILE[] = __FILE__; 
#endif 

namespace PolGlobal{

    //Dialog
    IMPLEMENT_DYNAMIC(CPOLBannerDlg, CDialog)

        /*! \fn CPOLBannerDlg::CPOLBannerDlg(CWnd* pParent)
        \brief Default Konstruktor
        \param pParent Parent Fenster
        */
        CPOLBannerDlg::CPOLBannerDlg(CWnd* pParent /*=NULL*/){}

    /*! \fn CPOLBannerDlg::~CPOLBannerDlg()
    \brief Destruktor
    */
    CPOLBannerDlg::~CPOLBannerDlg(){}

    /*! \fn void CPOLBannerDlg::DoDataExchange(CDataExchange* pDX)
    \brief Daten austausch mit Child- Controls
    \param pDX Pointer auf CDataExchange
    \return void
    */
    void CPOLBannerDlg::DoDataExchange(CDataExchange* pDX)
    {
        CDialog::DoDataExchange(pDX);
        DDX_Control(pDX, IDC_EDIT_BANER, m_ctrlEdit);
    }


    BEGIN_MESSAGE_MAP(CPOLBannerDlg, CDialog)
    END_MESSAGE_MAP()

    /*! \fn void CPOLBannerDlg::Show()
    \brief Ruft CDialog::Create und zeigt Dialog

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

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

        ShowWindow(SW_SHOW);
        UpdateWindow();
    }

    //Thread
    IMPLEMENT_DYNCREATE(CPOLBannerThread, CWinThread)

        /*! \fn CPOLBannerThread::CPOLBannerThread()
        \brief Default Konstruktor

        CPOLBannerThread::CPOLBannerThread(){}

    /*! \fn CPOLBannerThread::~CPOLBannerThread()
    \brief Destruktor
    */
    CPOLBannerThread::~CPOLBannerThread(){}

    /*! \fn BOOL CPOLBannerThread::InitInstance()
    \brief Thread Starten
    \return TRUE 

    Zeigth m_bannerWnd und setzt in dem Dialog Try to start ... String
    */
    BOOL CPOLBannerThread::InitInstance()
    {
        m_bannerWnd.Show();
        m_bannerWnd.m_ctrlEdit.SetWindowText(_T("Try to start ..."));
        return TRUE;
    }

    /*! \fn int CPOLBannerThread::ExitInstance()
    \brief Beendet Thread und zersört Dialog
    \return exit code aus dem Thread
    */
    int CPOLBannerThread::ExitInstance()
    {
        m_bannerWnd.ShowWindow(SW_HIDE);
        m_bannerWnd.DestroyWindow();

        return CWinThread::ExitInstance();
    }

    /*! \fn void CPOLBannerThread::SetMessage(LPCTSTR mes)
    \brief Setzt String in dem m_bannerWnd
    \param mes String zum Anzeigen
    \return void
    */
    void CPOLBannerThread::SetMessage(LPCTSTR mes){
        if(m_bannerWnd.m_ctrlEdit)
            m_bannerWnd.m_ctrlEdit.SetWindowText(mes);
    }




    BEGIN_MESSAGE_MAP(CPOLBannerThread, CWinThread)
    END_MESSAGE_MAP()

}

The class is called like this:

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 Stack says:

In the ENSURE(this != NULL); Line of IsKindOf the 'this' Variable is 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);
}

What happend here?
