线程问题

[smdszgzh]

我想在单击一个按钮时创建一个纯种，然后在线程里做这些事

UINT CMySerSocketDlg::ThreadSerFuc(LPVOID pParam)//线程函数，在头文件中已声明
	{
			WSADATA m_data;
	CString m_Msg,mMsg1;
	CWnd *hwnd=GetDlgItem(IDC_EDIT);
	if(WSAStartup(MAKEWORD(2,2),&m_data)!=0)
	{
		m_Msg="Load Socket Library failed!";
		hwnd->SetWindowText(m_Msg);
		return -1;

	}
	
	m_Msg="ff";
	hwnd->SetWindowText(m_Msg);
	SOCKET SerSocket=socket(AF_INET,SOCK_STREAM,IPPROTO_IP);
	SOCKET CliSocket;
	if(INVALID_SOCKET==SerSocket)
	{
		m_Msg="Create Socket Failed!";
		hwnd->SetWindowText(m_Msg);
		return -1;
	}
	sockaddr_in Seraddr,Cliaddr;
	Seraddr.sin_addr.S_un.S_addr=htonl(INADDR_ANY);
	Seraddr.sin_family=AF_INET;
	Seraddr.sin_port=htons(8000);
	bind(SerSocket,(sockaddr*)&Seraddr,sizeof(Seraddr)+1);
	int n=listen(SerSocket,5);
	if(n==SOCKET_ERROR)
	{
		m_Msg="Listen failed!";
		hwnd->SetWindowText(m_Msg);
		return -1;
	}
//	m_Msg="服务器已启动，等待用户连接!";
//	hwnd->SetWindowText(m_Msg);
	CWnd *hwnd1=GetDlgItem(IDC_EDIT1);
	while(true)
	{
		int m=sizeof(Cliaddr);
		CliSocket=accept(SerSocket,(sockaddr*)&Cliaddr,&m);
		char *recBuff=new char[100];
		char *sendBuff=new char[100];
		int length=_msize(recBuff);
		sendBuff="Wellcom!";
		send(CliSocket,sendBuff,length+1,0);
		m_Msg=sendBuff;
		hwnd->SetWindowText(m_Msg);
		while(true)
		{
			recv(CliSocket,recBuff,length+1,0);
			if(recBuff[0]=='q'||recBuff[0]=='Q')
			{
				m_Msg="用户请求退出!";
				hwnd->SetWindowText(m_Msg);
				return -1;
			}
			m_Msg=recBuff;
			hwnd->SetWindowText(recBuff);
			hwnd1->GetWindowText(mMsg1);
			recBuff=mMsg1.GetBuffer(mMsg1.GetLength());
			send(CliSocket,sendBuff,length+1,0);
			mMsg1.ReleaseBuffer();
			//mMsg1="";
		}

	}
	closesocket(SerSocket);
	WSACleanup();
	}

void CMySerSocketDlg::OnSet() 
{
	AfxBeginThread(ThreadSerFuc,NULL);//创建一个线程，不知道如何传递参数了

	// TODO: Add your control notification handler code here
	
}

提示错误 none of the 2 overloads can convert parameter 1 from type 'unsigned int (void *)'
我不知道怎么传递这个参数了，请高手指教，还有VC6里如果让代码对齐？？

[fandh]

是那句出错？

[smdszgzh]

'AfxBeginThread' : none of the 2 overloads can convert parameter 1 from type 'unsigned int (void *)'

[山的那边还是山~]

原型：

CWinThread* AfxBeginThread(
   AFX_THREADPROC pfnThreadProc,
   LPVOID pParam,
   int nPriority = THREAD_PRIORITY_NORMAL,
   UINT nStackSize = 0,
   DWORD dwCreateFlags = 0,
   LPSECURITY_ATTRIBUTES lpSecurityAttrs = NULL 
);

把这个：

AfxBeginThread(ThreadSerFuc,NULL);//创建一个线程，不知道如何传递参数了

改为：

AfxBeginThread(ThreadSerFuc, 0, THREAD_PRIORITY_NORMAL, 0, 0, NULL);

ThreadSerFuc 定义成静态成员函数

[Quote=引用 4 楼 oyljerry 的回复:]

static UINT ThreadSerFuc(LPVOID pParam)??

[oyljerry]

static UINT CMySerSocketDlg::ThreadSerFuc(LPVOID pParam)

[smdszgzh]

还是不行，会出更多问题
error C2724: 'ThreadSerFuc' : 'static' should not be used on member functions defined at file scope

执行 cl.exe 时出错.

把 UINT ThreadSerFuc(LPVOID pParam)方法定义到外面，当你用的时候就难它传入一个窗口句柄hwnd，调用GetDlgItem时就用hwndctrl= ::GetDlgItem（hwnd,IDC_EDIT）,::SetWindowText(hwndctrl,m_Msg);

[oyljerry]

线程函数中不能直接取CWnd::GetDlgItem，你可以在线程函数的参数LPVOID中传递CMySerSocketDlg*
