我现在能够加载窗口背景了 你提示下如果我不用CreateThread()能不能消除闪烁

……去看看

是不是和做个向导差不多？

……谁？ 有丁俊晖吗？

呵呵 偶尔看看斯诺克 还真带劲 喜欢丁俊晖

刚才去看了下WIN32汇编 哈哈 在原来的程序做了个小小的改动就OK 了 不过有点取巧。
把重绘区域锁定在一个范围后 就不干扰其他的图形了 这样的

void yrjd_OnTimer(HWND hWnd, UINT nIDEvent)
{
    RECT rect = {510, 200, 810, 400};
    choice = (choice + 1) % 6;
    InvalidateRect(hWnd, &rect, TRUE);  
}

....__

void yrjd_OnTimer(HWND hWnd, UINT nIDEvent)
{
    srand(time(NULL));
    RECT rect = {510, 200, 810, 400};
    choice = rand() % 6;
    InvalidateRect(hWnd, &rect, TRUE);  
}

发现在.cpp文件头加很多头文件不太好看 我为了随机显示又添加了两个头文件

今天还有两场半决赛吧 看好谁？奥沙利文？

大哥 再问个问题
我去搞了下兼容DC 大致流程这样

    HWND hWnd;
    HDC hdcBuf;
    HBITMAP hbmpBuf;
    RECT rect = {0, 0, 200, 200}
  
    HDC hdcMain = GetDC(hWnd);
    hdcBuf = CreateCompatibleDC(hdcMain);
    hbmpBuf = CreateCompatibleBitmap(hdcMain, 200, 200);
    SelectObject(hdcBuf, hbmpBuf);
    FillRect(hdcBuf, &rect, (HBRUSH)GetStockObject(WHITE_BRUSH));
    ReleaseDC(hWnd, hdcMain);

先创建一个窗口 hWnd 然后在这个窗口下衍生一个兼容设备hdcBuf 发现这时候如果想获取
hdcBuf的窗口句柄就无从下手，是不是内存DC不存在HWND呢？
有没有这种可能
先分别创建两个窗口hWnd1, hWnd2 他们对应的DC 分别是hdc1, hdc2
在通过一个什么法子让hdc2成为hdc1的兼容设备？这样我们就可以操控hdc2的窗口句柄hWnd2实现某些想
要的API功能。

  hTimer = SetTimer(0, 0, 55, ProcTimer);
   
   
    while( GetMessage(&msg , NULL, 0, 0) >0 )
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
   
    KillTimer(0, hTimer);

这段很有意思 WM_TIMER是在消息队列之外吗？
为什么 用目的窗口覆盖源窗口 程序会自行拷贝出很多子窗口 而且还超不出第一个目的窗口的范围？

在去看看……
