命名管道创建失败

我的程序菜单上有个按钮 点击就可以创建一个命名管道 但运行后点击 会弹出"创建命名管道失败"的窗口 我不知道哪边错了 各位知道的赐教啊 谢了先！！！
     
           hPipe=CreateNamedPipe("\\\\.\\pipe\\MyPipe",PIPE_ACCESS_DUPLEX | FILE_FLAG_OVERLAPPED,0,1,1024,1024,0,NULL);
    if(INVALID_HANDLE_VALUE==hPipe)
    {
        MessageBox("创建命名管道失败");
        hPipe=NULL;
        return;
    }

    HANDLE hEvent;
    hEvent=CreateEvent(NULL,TRUE,FALSE,NULL);
    if(!hEvent)
    {
        MessageBox("创建事件对象失败");
        CloseHandle(hPipe);
        hPipe=NULL;
        return;
    }

    OVERLAPPED ovlap;
    ZeroMemory(&ovlap,sizeof(OVERLAPPED));
    ovlap.hEvent=hEvent;

    if(!ConnectNamedPipe(hPipe,&ovlap))
    {
        if(ERROR_IO_PENDING!=GetLastError())
        {
            MessageBox("等待客户端连接失败");
            CloseHandle(hPipe);
            CloseHandle(hEvent);
            hPipe=NULL;
            return;
        }
    }

    if(WAIT_FAILED==WaitForSingleObject(hEvent,INFINITE))
    {
        MessageBox("等待对象失败");
        CloseHandle(hPipe);
        CloseHandle(hEvent);
        hPipe=NULL;
        return;
    }
    CloseHandle(hEvent); --------------------编程问答-------------------- getlasterror --------------------编程问答--------------------

//看看我这个非重叠的能成功否

BOOL CServerDlg::CreateServerPipe(LPCTSTR lpPipeName)

{

	m_hHandle = CreateNamedPipe(lpPipeName,PIPE_ACCESS_DUPLEX,

		PIPE_TYPE_MESSAGE|PIPE_READMODE_MESSAGE|PIPE_WAIT,

		PIPE_UNLIMITED_INSTANCES,BUFSIZE*sizeof(TCHAR),BUFSIZE*sizeof(TCHAR),

		NMPWAIT_USE_DEFAULT_WAIT,NULL);

	

	if(m_hHandle==INVALID_HANDLE_VALUE)

		return FALSE;

	if(!ConnectNamedPipe(m_hHandle,NULL))//一直等待客户端连接

	{

		CloseHandle(m_hHandle);

		m_hHandle = INVALID_HANDLE_VALUE;

		return FALSE;

	}

	return TRUE;

NATIVE的命名管道没用过,顶! --------------------编程问答-------------------- up~~~
