vc无法创建dialog? 400 报错

这是int CDialog::DoModal()里面的语句   

TRY
    {
        // create modeless dialog
        AfxHookWindowCreate(this);
        if (CreateDlgIndirect(lpDialogTemplate,CWnd::FromHandle(hWndParent), hInst))
        {
            if (m_nFlags & WF_CONTINUEMODAL)
            {
                // enter modal loop
                DWORD dwFlags = MLF_SHOWONIDLE;
                if (GetStyle() & DS_NOIDLEMSG)
                    dwFlags |= MLF_NOIDLEMSG;
                VERIFY(RunModalLoop(dwFlags) == m_nModalResult);
            }

            // hide the window before enabling the parent, etc.
            if (m_hWnd != NULL)
                SetWindowPos(NULL, 0, 0, 0, 0, SWP_HIDEWINDOW|
                    SWP_NOSIZE|SWP_NOMOVE|SWP_NOACTIVATE|SWP_NOZORDER);
        }
    }
    CATCH_ALL(e)
    {
        DELETE_EXCEPTION(e);
        m_nModalResult = -1;
    }

    END_CATCH_ALL

执行这个的时候出错if (CreateDlgIndirect(lpDialogTemplate,CWnd::FromHandle(hWndParent), hInst))

求解答方法。
