为什么关闭不了扫雷呀

[wjsr0409]

新手级别问题 谢谢大家

[whoo]

hwnd=FindWindow(NULL,"扫雷");

hwnd , hboom手误?


ps:
1. hboom 需要提到函数外作为全局变量。

2. 或者和关闭窗口放到一起：
case WM_LBUTTONDOWN:
hboom=FindWindow(NULL,"扫雷");
DestroyWindow(hboom);
return 0;


3. DestroyWindow管不了别人的窗口的。需要SendMessage(WM_QUIT);或者 WM_CLOSE，或者 SYSCOMMAND, SC_CLOSE。
