主要思路是：

1. 使用重叠 I/O（OVERLAPPED），避免阻塞 ConnectNamedPipe。
2. 额外创建一个“停止事件”（hStopEvent），在线程中与管道事件一起 WaitForMultipleObjects，一旦收到停止事件就马上退出循环。
3. 在主线程（或 OnNcDestroy）中 SetEvent(hStopEvent) 通知线程退出，然后再 CloseHandle 管道和事件。

// 假设这几个都是类成员或全局变量：
HANDLE hPipe = INVALID_HANDLE_VALUE;      // 管道句柄
HANDLE hStopEvent = NULL;                 // 停止事件
HANDLE hOvEvent   = NULL;                 // OVERLAPPED 事件
HANDLE hThread    = NULL;                 // 工作线程句柄bool OpenPipe(MsgHandleInterface* msgHandle)
{// 1. 创建停止事件（自动重置、初始未置位）hStopEvent = CreateEvent(nullptr, FALSE, FALSE, nullptr);if (!hStopEvent) return false;// 2. 创建 OVERLAPPED 专用事件hOvEvent = CreateEvent(nullptr, FALSE, FALSE, nullptr);if (!hOvEvent) {CloseHandle(hStopEvent);return false;}// 3. 创建命名管道，注意 FILE_FLAG_OVERLAPPEDLPCTSTR lpszPipename = TEXT(CMWAITMSGPIPENAME);hPipe = CreateNamedPipe(lpszPipename,PIPE_ACCESS_INBOUND | FILE_FLAG_OVERLAPPED,  // 重叠模式PIPE_TYPE_MESSAGE | PIPE_READMODE_MESSAGE | PIPE_WAIT,1,BUFSIZE,BUFSIZE,0,NULL);if (hPipe == INVALID_HANDLE_VALUE) {CloseHandle(hOvEvent);CloseHandle(hStopEvent);return false;}// 4. 启动后台线程DWORD dwThreadId = 0;hThread = CreateThread(NULL,0,waitConnectThread,(LPVOID)msgHandle,    // 如果需要传递 msgHandle，可用结构体打包0,&dwThreadId);if (!hThread) {CloseHandle(hPipe);CloseHandle(hOvEvent);CloseHandle(hStopEvent);return false;}msgHandleObj = msgHandle;return true;
}// 窗口销毁或退出时调用
void ClosePipe()
{if (hStopEvent) {// 通知线程退出SetEvent(hStopEvent);}if (hThread) {// 等待线程结束WaitForSingleObject(hThread, INFINITE);CloseHandle(hThread);hThread = NULL;}if (hPipe != INVALID_HANDLE_VALUE) {CloseHandle(hPipe);hPipe = INVALID_HANDLE_VALUE;}if (hOvEvent) {CloseHandle(hOvEvent);hOvEvent = NULL;}if (hStopEvent) {CloseHandle(hStopEvent);hStopEvent = NULL;}
