线程函数调用问题

Question

我在MFC初始化的创建了线程: AA = CreateThread(NULL, 0, TGS, NULL, 0, NULL); 然后我响应了两个按钮控件函数,当我点击第一个按钮控件时我想执行线程函数:TGS(), 并且在TGS() 执行期间我想点击第二个按钮控件去执行第二个按钮控件函数,要怎么做才能完成这个效果?

我之前试过在第一个按钮控件函数里直接调用线程函数: TGS(); 但是要等到该线程函数执行完才能继续响应其他控件消息,这不是我要的效果,请高手帮帮忙,谢谢!

你好，

你可以考虑用异步多线程模式实现。具体实现方式需要你先了解清楚里面的机制自己试着实现。

取决您线程函数，比如您的线程的实现如下所示：
DWORD WINAPI ThreadProc(LPVOID lParam)
{
  MSG msg;
  BOOL bExitThread = FALSE;
  while(!bExitThread && GetMessage(&msg, NULL, 0, 0))
  {
    switch(msg.message)
    {
        case MSG_DOSOMETHING: // 您可以利用PostThreadMessage给该线程发送消息，让线程做事情
         // TODO:
        break;
        case MSG_EXIT:  //  发送消息给线程，让线程退出
         bExitThread = TRUE;
         break;
       default:
          break;
    }
  }
  return 0;
}
