windows編程 全屏窗口的創建總結
第一種：較簡單的方法
在ShowWindow(hwnd,SW_SHOWNORMAL);
UpdateWindow(hwnd);前加如下代碼:

LONG style = GetWindowLong(hwnd,GWL_STYLE);//獲得窗口風格
style = &~WS_CAPTION & ~WS_SIZEBOX;//窗口全屏顯示且不可改變大小
SetWindowLong(hwnd,GWL_STYLE,style); //設置窗口風格
int screenX = GetSystemMetrics(SM_CXSCREEN);//獲取整個屏幕右下角X坐標
int screenY = GetSystemMetrics(SM_CYSCREEN);//屏幕Y坐標
SetWindowPos(hwnd, NULL,0,0,screenX,screenY,SWP_NOZORDER);//改變窗口位置、尺寸和Z序
ShowCursor(FALSE);//顯示時隱藏鼠標

LONG style = GetWindowLong(hwnd,GWL_STYLE);//獲得窗口風格
style = &~WS_CAPTION & ~WS_SIZEBOX;//窗口全屏顯示且不可改變大小
SetWindowLong(hwnd,GWL_STYLE,style); //設置窗口風格
int screenX = GetSystemMetrics(SM_CXSCREEN);//獲取整個屏幕右下角X坐標
int screenY = GetSystemMetrics(SM_CYSCREEN);//屏幕Y坐標
SetWindowPos(hwnd, NULL,0,0,screenX,screenY,SWP_NOZORDER);//改變窗口位置、尺寸和Z序
ShowCursor(FALSE);//顯示時隱藏鼠標

 

第二種：在按下esc后實現全屏  

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;
}

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;
}

 

第三種：在消息中加入一下代碼

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);

//去除標題和邊框
       SetWindowLong(hWnd, GWL_STYLE,
       GetWindowLong(hWnd, GWL_STYLE) &
       (~(WS_CAPTION | WS_BORDER)));

// 置對話框為最頂端並擴充到整個屏幕
 ::SetWindowPos(hWnd, HWND_TOPMOST,
   -(GetSystemMetrics(SM_CXBORDER)+1),
  -(GetSystemMetrics(SM_CYBORDER)+1),
 +1,cy+1, SWP_NOZORDER)；
}

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);

//去除標題和邊框
       SetWindowLong(hWnd, GWL_STYLE,
       GetWindowLong(hWnd, GWL_STYLE) &
       (~(WS_CAPTION | WS_BORDER)));

// 置對話框為最頂端並擴充到整個屏幕
 ::SetWindowPos(hWnd, HWND_TOPMOST,
   -(GetSystemMetrics(SM_CXBORDER)+1),
  -(GetSystemMetrics(SM_CYBORDER)+1), 
 +1,cy+1, SWP_NOZORDER)；
}

以上幾種方法需要注意的是在注冊窗口類中的菜單項，如果不顯示菜單就要把lpszMenuName設為null，否則會在全屏的窗口上顯示菜單。
