分割窗口时CFormView与Pane关联时出现的问题

分割窗口时,其中一个窗格Pane,所关联的视,这个视若是从 CEditView, CTreeView, CView等类导出的,则没有问题,若是从 CFormView导出的, 那么编译正常,但执行那个时会出现

错误,

原因是 CFormView 的导出类,需要与一个Dialog资源关联,这个Dialog的属性必须是ws_childStyle必须选 “下层”SystemMenuTitleBar属性最好都设为False

以前在出现

 

错误提示时,不知如何处理,在这次通过点击“重试”,debugger停在了

 

the debugge point to this line

Code:

               ASSERT(FALSE);          // invalid dialog template name

which appears in the following code snippet of the file VIEWFORM.cpp

Code:

BOOL CFormView::Create(LPCTSTR /*lpszClassName*/, LPCTSTR /*lpszWindowName*/,

        DWORD dwRequestedStyle, const RECT& rect, CWnd* pParentWnd, UINT nID,

        CCreateContext* pContext)

{

        ASSERT(pParentWnd != NULL);

        ASSERT(m_lpszTemplateName != NULL);

 

        m_pCreateContext = pContext;    // save state for later OnCreate

 

#ifdef _DEBUG

        // dialog template must exist and be invisible with WS_CHILD set

        if (!_AfxCheckDialogTemplate(m_lpszTemplateName, TRUE))

        {

               ASSERT(FALSE);   //<====== debugger stops at this line       // invalid dialog template name

               PostNcDestroy();        // cleanup if Create fails too soon

               return FALSE;

        }

#endif //_DEBUG

 

        // initialize common controls

        VERIFY(AfxDeferRegisterClass(AFX_WNDCOMMCTLS_REG));

        AfxDeferRegisterClass(AFX_WNDCOMMCTLSNEW_REG);

 

        // call PreCreateWindow to get prefered extended style

        CREATESTRUCT cs; memset(&cs, 0, sizeof(CREATESTRUCT));

        if (dwRequestedStyle == 0)

               dwRequestedStyle = AFX_WS_DEFAULT_VIEW;

        cs.style = dwRequestedStyle;

        if (!PreCreateWindow(cs))

               return FALSE;

 

        // create a modeless dialog

        if (!CreateDlg(m_lpszTemplateName, pParentWnd))

               return FALSE;

 

        m_pCreateContext = NULL;

 

        // we use the style from the template - but make sure that

        //  the WS_BORDER bit is correct

        // the WS_BORDER bit will be whatever is in dwRequestedStyle

        ModifyStyle(WS_BORDER|WS_CAPTION, cs.style & (WS_BORDER|WS_CAPTION));

        ModifyStyleEx(WS_EX_CLIENTEDGE, cs.dwExStyle & WS_EX_CLIENTEDGE);

 

        SetDlgCtrlID(nID);

 

        CRect rectTemplate;

        GetWindowRect(rectTemplate);

        SetScrollSizes(MM_TEXT, rectTemplate.Size());

 

        // initialize controls etc

        if (!ExecuteDlgInit(m_lpszTemplateName))

               return FALSE;

 

        // force the size requested

        SetWindowPos(NULL, rect.left, rect.top,

               rect.right - rect.left, rect.bottom - rect.top,

               SWP_NOZORDER|SWP_NOACTIVATE);

 

        // make visible if requested

        if (dwRequestedStyle & WS_VISIBLE)

               ShowWindow(SW_NORMAL);

 

        return TRUE;

}
