Create CListCtrl from dll

---------------------------DLL A----------------------------------
#ifdef SELIBCTRL_IMP
#define SELIBCTRL_API           __declspec(dllexport)
#define SELIBCTRL_EXT_CLASS    AFX_CLASS_EXPORT
#else
#define SELIBCTRL_API           __declspec(dllimport)
#define SELIBCTRL_EXT_CLASS    AFX_CLASS_IMPORT
#endif

class IListCtrl
{
   ...
};

SELIBCTRL_API IListCtrl* CreateIListCtrl(HWND hParent);

class CMyListCtrl : public CListCtrl, public IListCtrl
{
     ...
};
----------------------------DLL B------------------------------
void Test::CreateList()
{
    IListCtrl* pList = CreateIListCtrl(this->GetSafeHwnd());
}
---------------------------------------------------------------

I use a dll interface to create a CMyListCtrl, and override DrawItem(),
but it cant receive ownerdraw message,so DrawItem() is always not running, only can receive move event.

PS:I try use AFX_MANAGE_STATE(AfxGetStaticModuleState()), but its no useful

If dont use A dll, move the CMyListCtrl class to the B dll, it will be OK,
Why is this problem? Can anyone give me a suggestion? Thanks.
