mfc實現播放器功能，雙擊全屏，再雙擊還原

視頻播放器的制作，視頻流在靜態控件上顯示，類似迅雷看看雙擊全屏操作的實現
 
在主窗口的 .h 文件中
[cpp]
BOOL m_isFullScreen; 
CRect m_Old; 
BOOL PreTranslateMessage(MSG* pMsg); 
 
nbsp;afx_msg void OnDoubleStatic(UINT nFlags,CPoint point); //雙擊靜態控件（顯示視頻）響應函數 
 
.cpp文件中
[cpp]  
//定義消息相應     
 ON_STN_DBLCLK(IDC_STATIC_VIDEOWND,OnDoubleStatic) ON_STN_DBLCLK(IDC_STATIC_VIDEOWND,OnDoubleStatic) 
 
//在主窗口 .cpp 文件中的初始化函數中先獲取原始的位置 
m_videoWnd.GetWindowRect(&m_Old);  
ScreenToClient(&m_Old); 
 
在主窗口 .cpp 文件中
[cpp] 
// 
void CTestVoxCVSA_DemoDlg::OnDoubleStatic(UINT nFlags,CPoint point) 
{ 
    CTestVoxCVSA_DemoDlg* m_pDemoDlg = (CTestVoxCVSA_DemoDlg*)AfxGetApp()->m_pMainWnd; 
    if (m_isFullScreen == FALSE) 
    { 
        CWnd *saveParent=m_videoWnd.GetParent();  
        m_videoWnd.SetParent(GetDesktopWindow());  
        CRect rect;  
        GetDesktopWindow()-> GetWindowRect(&rect);  
        m_videoWnd.SetWindowPos(&wndTopMost,rect.left,rect.top,rect.right,rect.bottom,SWP_SHOWWINDOW);  
        m_pDemoDlg->ShowWindow(SW_HIDE); 
        m_isFullScreen = TRUE; 
    } 
    CDialog::OnLButtonDblClk(nFlags,point); 
} 
 
//獲取消息的函數 
BOOL CTestVoxCVSA_DemoDlg::PreTranslateMessage(MSG* pMsg) 
{ 
    CTestVoxCVSA_DemoDlg* m_pDemoDlg = (CTestVoxCVSA_DemoDlg*)AfxGetApp()->m_pMainWnd; 
    if ((pMsg->message==WM_LBUTTONDBLCLK)&&(m_isFullScreen == TRUE)) 
    { 
        m_pDemoDlg->ShowWindow(SW_SHOW); 
        m_videoWnd.SetParent(m_pDemoDlg); 
        m_videoWnd.SetWindowPos(&wndTop,m_Old.left,m_Old.top,m_Old.right-m_Old.left,m_Old.bottom-m_Old.top,SWP_SHOWWINDOW); 
        m_isFullScreen = FALSE; 
        return TRUE; 
    } 
    return CWnd::PreTranslateMessage(pMsg); 
}
