网上介绍ActiveX视频空间全屏的文章很多，我借鉴了一些代码，作了些自己的修改，如下：


点播放窗口右键
1.把嵌入在ActiveX里有窗体“跳”出来
2.隐藏任务栏
再次点击和上面相反，又回到了这个ActiveX里去了


bool m_bFullScreen=false;  

HWND m_hWndParent;

CRect m_rcCtrlRect;


void CDlgMain::fullScreen()

{

    m_bFullScreen=!m_bFullScreen; // 设置全屏显示标志


    if(m_bFullScreen)//全屏显示   

    {  

        //用MFC隐藏系统任务栏

        CWnd * wnd = FindWindow("Shell_TrayWnd",NULL);

        wnd->SetWindowPos(NULL,0,0,0,0,SWP_HIDEWINDOW);  

        

        GetWindowRect(m_rcCtrlRect);  

        m_hWndParent=::GetParent(m_hWnd);

        ::SetParent(m_hWnd,::GetDesktopWindow());  

        int   nScreenWidth=GetSystemMetrics(SM_CXSCREEN);  

        int   nScreenHeight=GetSystemMetrics(SM_CYSCREEN);

        ::SetWindowPos(m_hWnd,HWND_TOPMOST,0,0,nScreenWidth,nScreenHeight

                                                ,SWP_FRAMECHANGED|SWP_DEFERERASE);

    }  

    else  

    {  

        //用MFC显示系统任务栏

        CWnd * wnd = FindWindow("Shell_TrayWnd",NULL);

        wnd->SetWindowPos(NULL,0,0,0,0,SWP_SHOWWINDOW);  

        

        ::SetParent(m_hWnd,m_hWndParent);  

        

        CPoint LeftTop(m_rcCtrlRect.TopLeft());

        CPoint BottomRight(m_rcCtrlRect.BottomRight());

        ::ScreenToClient(m_hWnd,&LeftTop); 

        ::ScreenToClient(m_hWnd,&BottomRight); 

        ::MoveWindow(m_hWnd,LeftTop.x,LeftTop.y,m_rcCtrlRect.Width()

                                                        ,m_rcCtrlRect.Height(),TRUE);

        ::SetWindowPos(m_hWnd,HWND_NOTOPMOST,0,0,0,0

                                                        ,SWP_NOMOVE|SWP_NOSIZE);

    }  

}
