if ( FindWindow(NULL,"1")==0 && FindWindow(NULL,"0")==0) 在这里我该怎样用这句结束呢?

我想在这段代码里,没有窗口1和0就退出.
if ( FindWindow(NULL,"1")==0 && FindWindow(NULL,"0")==0)
ExitProcess(1);
这句放哪?

[yelvfujiamian]

这结构真是太复杂了.

[ringphone]

放窗口循环里面就可以
while (GetMessage(&msg, NULL, 0, 0))
{
if ( FindWindow(NULL,"1")==0 && FindWindow(NULL,"0")==0)
ExitProcess(1);

if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}

[cclk-1024]

SendMessage(m_hwd,WM_CLOSE,0,0);m_hwd是你想关闭的句柄
或者直接return到你调用的地方

[yelvfujiamian]

每隔一段时间检查一下有没有窗口1和0.
