隐藏系统任务栏

最简单的方法为:

FindWindow("Shell_TrayWnd",NULL)->ShowWindow(SW_HIDE);

上面代码确能隐藏任务栏,但是,随便打开一个窗口最大化,原来任务栏的地方仍被空白占据着。调用Win32 API- SystemParametersInfo(SPI_SETWORKAREA),重新设置桌面工作区域,可解决这个问题,代码如下:

void gShowHideTaskBar(BOOL bHide /*=FALSE*/) 
{ 
    CRect rectWorkArea = CRect(0,0,0,0); 
    CRect rectTaskBar = CRect(0,0,0,0); 

    CWnd* pWnd = CWnd::FindWindow(_T("Shell_TrayWnd"), NULL); 

    if( bHide ) 
    { 
        // Code to Hide the System Task Bar 
        SystemParametersInfo(SPI_GETWORKAREA, 
            0, 
            (LPVOID)&rectWorkArea, 
            0); 

        if( pWnd ) 
        { 
            pWnd->GetWindowRect(rectTaskBar); 
            rectWorkArea.bottom += rectTaskBar.Height(); 
            SystemParametersInfo(SPI_SETWORKAREA, 
                0, 
                (LPVOID)&rectWorkArea, 
                0); 

            pWnd->ShowWindow(SW_HIDE); 
        } 
    } 
    else 
    { 
        // Code to Show the System Task Bar 
        SystemParametersInfo(SPI_GETWORKAREA, 
            0, 
            (LPVOID)&rectWorkArea, 
            0); 
        if( pWnd ) 
        { 
            pWnd->GetWindowRect(rectTaskBar); 
            rectWorkArea.bottom -= rectTaskBar.Height(); 
            SystemParametersInfo(SPI_SETWORKAREA, 
                0, 
                (LPVOID)&rectWorkArea, 
                0); 

            pWnd->ShowWindow(SW_SHOW); 
        } 
    } 
}
