Time being i fixed it by the following code ...

#ifdef _AFXDLL

    CString version;
    version.Format("%d",_XTPLIB_VERSION_PREFIX);       

    // search classes in shared DLLs
    for (CDynLinkLibrary* pDLL = pModuleState->m_libraryList; pDLL != NULL;
    pDLL = pDLL->m_pNextDLL)
    {
        char buff[MAX_PATH];
        memset(buff,0,MAX_PATH);

        ::GetModuleFileName(pDLL->m_hModule,buff,MAX_PATH);

        if(CString(buff).Find(version) != -1)       
        {
            for (pClass = pDLL->m_classList; pClass != NULL;
            pClass = pClass->m_pNextClass)
            {
                if (lstrcmpA(szClassName, pClass->m_lpszClassName) == 0)
                {
                    return pClass;
                }
            }
        }
    }
#endif

Whoop! Finally find out the problem, My exe uses some dlls that still not ported to new XT version (which the exe uses) so the old XT dll come in the dynalib list and messed up the things.

Hearty Thanks Oleg for your patient and support.

pClass get value like string only in the Red code region not in the Blue code region.

CRuntimeClass* CXTPPropExchange::FindRuntimeClass(LPCSTR szClassName)
{

    CRuntimeClass* pClass;
    // search app specific classes
    AFX_MODULE_STATE* pModuleState = AfxGetModuleState();

    for (pClass = pModuleState->m_classList; pClass != NULL;
    pClass = pClass->m_pNextClass)
    {
        if (lstrcmpA(szClassName, pClass->m_lpszClassName) == 0)
        {
            return pClass;
        }
    }

#ifdef _AFXDLL
    // search classes in shared DLLs
    for (CDynLinkLibrary* pDLL = pModuleState->m_libraryList; pDLL != NULL;
    pDLL = pDLL->m_pNextDLL)
    {
        for (pClass = pDLL->m_classList; pClass != NULL;
        pClass = pClass->m_pNextClass)
        {
            if (lstrcmpA(szClassName, pClass->m_lpszClassName) == 0)
            {
                return pClass;
            }
        }
    }
#endif
    ASSERT(FALSE);
    return 0;
}

When i try using CustomizeDlg sample the pClass in

CRuntimeClass* CXTPPropExchange::FindRuntimeClass(LPCSTR szClassName)

has value like "struct CRuntimeClass CXTPMenuBar::classCXTPMenuBar"
but when i try using my app exe the value became like "CXTPMenuBar" ?

Hi,

Code to check

BOOL CXTPPropExchange::ExchangeObjectInstance(CObject*& pObject, CRuntimeClass* pObjectRuntime)
{
    if (!IsLoading())
    {
        CRuntimeClass* pClass = pObject->GetRuntimeClass();
        PX_RuntimeClass(this, _T("Class"), pClass, pObjectRuntime);
    }
    else
    {
        CRuntimeClass* pClass = NULL;
        PX_RuntimeClass(this, _T("Class"), pClass, pObjectRuntime);
        if (!pClass)
            return FALSE;       

        const CRuntimeClass* pClassThis = pClass;
        while (pClassThis != NULL)
        {
            if (pClassThis == pObjectRuntime)
                return TRUE;
    #ifdef _AFXDLL
            pClassThis = (*pClassThis->m_pfnGetBaseClass)();
    #else
            pClassThis = pClassThis->m_pBaseClass;
    #endif
        }
        return FALSE;       // walked to the top, no match

        pObject = (CObject*)AfxDynamicDownCast(pObjectRuntime, pClass->CreateObject());

        if (!pObject)
            return FALSE;
    }
    return TRUE;
}

Hi,

In, BOOL CRuntimeClass::IsDerivedFrom(const CRuntimeClass* pBaseClass) const

the line if (pClassThis == pBaseClass) returns FALSE

When pClassThis is "CXTPCommandBar" and pBaseClass is "struct CRuntimeClass CXTPCommandBar::classCXTPCommandBar"

Is that ring any bell ?

Thanks Oleg,

Yes after adding AfxOleInit() the customizedlg sample works correctly.
But still i didnt find the way to reproduce the same problem in my app.
