This topic is included for completeness. For more detail see the source code located in the VC\atlmfc\src\mfc folder of your Visual Studio installation.

The CMDIChildWndEx class provides the functionality of a Windows multiple document interface (MDI) child window. It extends the functionality of CMDIChildWnd Class. The framework requires this class when an MDI application uses certain MFC classes.

Remarks

To take advantage of extended docking features in MDI applications, derive the MDI child window class of your application from CMDIChildWndEx instead of CMDIChildWnd.

Example

The following example derives a class from CMDIChildWndEx. This code snippet comes from the VisualStudioDemo Sample: MFC Visual Studio Application.

class CChildFrame : public CMDIChildWndEx
{
    DECLARE_DYNCREATE(CChildFrame)
public:
    CChildFrame();

// Overrides 
public:
    virtual BOOL PreCreateWindow(CREATESTRUCT& cs);
    virtual void ActivateFrame(int nCmdShow = -1);

    virtual BOOL IsReadOnly();
    virtual LPCTSTR GetDocumentName(CObject** pObj);

// Implementation 
public:
    virtual ~CChildFrame();
#ifdef _DEBUG
    virtual void AssertValid() const;
    virtual void Dump(CDumpContext& dc) const;
#endif

protected:
    afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);

    DECLARE_MESSAGE_MAP()
};
