windows编程 全屏窗口的创建总结 .

windows编程 全屏窗口的创建总结
第一种：较简单的方法
在ShowWindow(hwnd,SW_SHOWNORMAL);
UpdateWindow(hwnd);前加如下代码:

LONG style = GetWindowLong(hwnd,GWL_STYLE);//获得窗口风格
style = &~WS_CAPTION & ~WS_SIZEBOX;//窗口全屏显示且不可改变大小
SetWindowLong(hwnd,GWL_STYLE,style); //设置窗口风格
int screenX = GetSystemMetrics(SM_CXSCREEN);//获取整个屏幕右下角X坐标
int screenY = GetSystemMetrics(SM_CYSCREEN);//屏幕Y坐标
SetWindowPos(hwnd, NULL,0,0,screenX,screenY,SWP_NOZORDER);//改变窗口位置、尺寸和Z序
ShowCursor(FALSE);//显示时隐藏鼠标

第二种：在按下esc后实现全屏  

switch (message)
{
case WM_KEYDOWN:
 switch(wParam)
 {
 case VK_ESCAPE:
 {
   HWND    hDesk;   
   RECT    rc;   
   hDesk   =    GetDesktopWindow();   
  GetWindowRect(    hDesk,   &rc    );   
  SetWindowLong(    hWnd,    GWL_STYLE,    WS_BORDER    );   
  SetWindowPos( hWnd,    HWND_TOPMOST,0,0, rc.right, rc.bottom,     

     SWP_SHOWWINDOW);
   }
    break;
     }
 return 0;
}

第三种：在消息中加入一下代码

static int cx, cy, cxDib, cyDib;
hdc=::GetDC(NULL);
switch (message)
{
  case WM_CREATE:
 cx = GetDeviceCaps(hdc,HORZRES) +
  GetSystemMetrics(SM_CXBORDER);
       cy = GetDeviceCaps(hdc,VERTRES) +
 GetSystemMetrics(SM_CYBORDER);
   ::ReleaseDC(0,hdc);

//去除标题和边框
       SetWindowLong(hWnd, GWL_STYLE,
       GetWindowLong(hWnd, GWL_STYLE) &
       (~(WS_CAPTION | WS_BORDER)));

// 置对话框为最顶端并扩充到整个屏幕
 ::SetWindowPos(hWnd, HWND_TOPMOST,
   -(GetSystemMetrics(SM_CXBORDER)+1),
  -(GetSystemMetrics(SM_CYBORDER)+1), 
 +1,cy+1, SWP_NOZORDER)；
}
