[求助]第一次编译连接正切，第二次..

第一次编译连接正常无错误，就是运行时没有效果
第二次　编译，连接时
Linking...
LINK : fatal error LNK1168: cannot open Debug/5.exe for writing
Error executing link.exe.

5.exe - 1 error(s), 0 warning(s)

这是什么错误呢？

剛看了一下, 你的 WNDCLASS 的 lpszClassName 定義成 "彩單", 在建立 Window 時使用了 "5_1 " 作爲 ClassName?

case IDM_EXIT:
這裏用了 SendMessage, SendMessage 函式會等待指定的窗口處理完消息返回,
你 SendMessage 發送 WM_DESTROY 給窗口, 又返回, 這時窗口已經 Destroy 了,
返回給誰了? 用 PostMessage 發送 WM_CLOSE 吧

還有就是關於 wndproc 的返回值, 不太習慣這種寫法, 只是在特定情況下返回 0,
不是說你的有錯...

.....wndproc......
{
switch(uMsg)
{
...
case WM_DESTROY:
PostQuitMessage(0);
return 0L;
}
return Def........
}
