eVC中全屏显示的实现

void CLpllpDlg::FullScreenDialog(HWND hDlg) 
{ 
    int x0,y0,cx, cy;   
    x0 = -(GetSystemMetrics(SM_CXBORDER)+1);
    y0 = -(GetSystemMetrics(SM_CYBORDER)+1);
    HDC dc = ::GetDC(NULL);     
    //HDC dc = ::GetWindowDC( HWND_DESKTOP ); 
    cx = GetDeviceCaps(dc,HORZRES) + GetSystemMetrics(SM_CXBORDER);     
    cy = GetDeviceCaps(dc,VERTRES) + GetSystemMetrics(SM_CYBORDER);     
    ::ReleaseDC(0,dc); 

    //去除标题和边框 
    SetWindowLong(m_hWnd,GWL_STYLE,GetWindowLong(m_hWnd,GWL_STYLE)&(~(WS_CAPTION|WS_BORDER)));     
    //置对话框为最顶端并扩充到整个屏幕 
    ::SetWindowPos(m_hWnd, HWND_TOPMOST, x0, y0, cx+1, cy+1, SWP_NOZORDER);  
    //隐藏任务栏
    HWND hTaskBar;
    hTaskBar = ::FindWindow(TEXT("HHTaskBar"), NULL); //搜寻任务栏句柄
    ::ShowWindow(hTaskBar, SW_HIDE); //隐藏
    // ShowWindow(hTaskBar, SW_SHOWNORMAL); //显示任务栏
}

HWND hw = this->GetSafeHwnd();
FullScreenDialog( hw);
::SetForegroundWindow(hw);

如想保留标题，直接去掉&后面的就可以了！

在Mobile5.0上，上面的方式是无效的，需调用如下：

SetForegroundWindow(); //此函数不调用，则SHFullScreen将无效

// To switch to full screen mode, first hide all of the shell parts.
dwState = (SHFS_HIDETASKBAR | SHFS_HIDESTARTICON | SHFS_HIDESIPBUTTON);
SHFullScreen(hWnd, dwState);

RECT rc;
SetRect(&rc, 0, 0, GetSystemMetrics(SM_CXSCREEN), GetSystemMetrics(SM_CYSCREEN));
::MoveWindow(m_hWnd, rc.left, rc.top, rc.right-rc.left, rc.bottom-rc.top, TRUE);

this->m_bFullScreen = false; //不执行此句将有不同的效果
