<br>主题：关于CAsyncSocket连接的问题，请大家指教
<br>内容：我编了一个简单的客户/服务器软件，但是在连接时出错，不知道为什么请大家指点。现把源码贴上。(谢谢哈！）<BR>客户端：<BR>/////ClientSock.h<BR>class CClientSock : public CAsyncSocket<BR>{<BR>// Attributes<BR>public:<BR>// Operations<BR>public:<BR> CClientSock();<BR> virtual ~CClientSock();<BR>// Overrides<BR>public:<BR> // ClassWizard generated virtual function // Implementation<BR>protected:<BR>};<BR>///ClientSock.cpp<BR>CClientSock::CClientSock()<BR>{<BR>}<BR>CClientSock::~CClientSock()<BR>{<BR>}<BR><BR>////ClientAsyncSocketDlg.h<BR>#include "ClientSock.h"<BR>// CClientAsyncSocketDlg dialog<BR>class CClientAsyncSocketDlg : public CDialog<BR>{<BR>// Construction<BR>public:<BR> CClientAsyncSocketDlg(CWnd* pParent = NULL); // standard constructor<BR> CClientSock m_Clientsock;<BR>// Dialog Data<BR> //{{AFX_DATA(CClientAsyncSocketDlg)<BR> enum { IDD = IDD_CLIENTASYNCSOCKET_DIALOG };<BR> CString m_strMessage;<BR> CString m_strName;<BR> int m_iPort;<BR> //}}AFX_DATA<BR> // ClassWizard generated virtual function overrides<BR> //{{AFX_VIRTUAL(CClientAsyncSocketDlg)<BR> protected:<BR> virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support<BR> //}}AFX_VIRTUAL<BR>// Implementation<BR>protected:<BR> HICON m_hIcon;<BR><BR> // Generated message map functions<BR> //{{AFX_MSG(CClientAsyncSocketDlg)<BR> virtual BOOL OnInitDialog();<BR> afx_msg void OnSysCommand(UINT nID, LPARAM lParam);<BR> afx_msg void OnPaint();<BR> afx_msg HCURSOR OnQueryDragIcon();<BR> afx_msg void OnBsend();<BR> afx_msg void OnBconnect();<BR> //}}AFX_MSG<BR> DECLARE_MESSAGE_MAP()<BR>};<BR>/////ClientAsyncSocketDlg.cpp<BR>void CClientAsyncSocketDlg::OnBsend() <BR>{ <BR> int iLen;<BR> int iSent;<BR> this->UpdateData(true);<BR>if(this->m_strMessage!="")<BR>{<BR> iLen=m_strMessage.GetLength();<BR> iSent=m_Clientsock.Send(LPCTSTR(m_strMessage),iLen);<BR> if (iLen == SOCKET_ERROR ) <BR> { <BR> DWORD dwErr=CAsyncSocket::GetLastError(); <BR> return; <BR> }<BR> }<BR>}<BR><BR>void CClientAsyncSocketDlg::OnBconnect() <BR>{<BR> this->UpdateData(true);<BR> if(!this->m_Clientsock.Create())<BR>{ DWORD dwErr=CAsyncSocket::GetLastError(); <BR> return;<BR>} <BR> if(!this->m_Clientsock.Connect((LPCTSTR（m_strName,m_iPort))<BR>{<BR> DWORD dwErr=CAsyncSocket::GetLastError(); <BR> return;<BR>} <BR>}<BR>服务器端<BR>/////ServeSocket.h<BR>class CServerAsyncSocketDlg;<BR>// CServeSocket command target<BR>class CServeSocket : public CAsyncSocket<BR>{<BR>public:<BR> CServerAsyncSocketDlg* pWnd;<BR>public:<BR> CServeSocket();<BR> virtual ~CServeSocket();<BR>// Overrides<BR>public:<BR> // ClassWizard generated virtual function overrides<BR> //{{AFX_VIRTUAL(CServeSocket)<BR> public:<BR> virtual void OnAccept(int nErrorCode);<BR> virtual void OnReceive(int nErrorCode);<BR> //}}AFX_VIRTUAL<BR><BR> // Generated message map functions<BR> //{{AFX_MSG(CServeSocket)<BR> // NOTE - the ClassWizard will add and remove member functions here.<BR> //}}AFX_MSG<BR>// Implementation<BR>protected:<BR>};<BR>CServeSocket::CServeSocket()<BR>{<BR>}<BR><BR>CServeSocket::~CServeSocket()<BR>{<BR>}<BR><BR>////////ServeSocket.cpp<BR>// CServeSocket member functions<BR>void CServeSocket::OnAccept(int nErrorCode) <BR>{ <BR> if(nErrorCode==0)<BR> { <BR> if (!Accept(pWnd->m_servesock)) <BR> { <BR> DWORD dwErr = CAsyncSocket::GetLastError(); <BR> return; <BR> } <BR> }<BR> CAsyncSocket::OnAccept(nErrorCode);<BR>}<BR><BR>void CServeSocket::OnReceive(int nErrorCode) <BR>{<BR>if(nErrorCode==0)<BR>{<BR> char szBuf[CHAR_MAX]; <BR> memset(szBuf, 0, sizeof(szBuf)); <BR> int iLen = Receive(szBuf, sizeof(szBuf)); <BR> if (!iLen ) <BR> { <BR> DWORD dwErr = CAsyncSocket::GetLastError(); <BR> return; <BR> }<BR>}<BR> CAsyncSocket::OnReceive(nErrorCode);<BR>}<BR>////ServerAsyncSocketDlg.h<BR>class CServerAsyncSocketDlg : public CDialog<BR>{<BR>public:<BR>CServerAsyncSocketDlg(CWnd* pParent = NULL);<BR>CServeSocket m_servesock;<BR>// Dialog Data<BR> //{{AFX_DATA(CServerAsyncSocketDlg)<BR> enum { IDD = IDD_SERVERASYNCSOCKET_DIALOG };<BR> CListBox m_lReceive;<BR> int m_iPort;<BR> //}}AFX_DATA<BR> // ClassWizard generated virtual function overrides<BR> //{{AFX_VIRTUAL(CServerAsyncSocketDlg)<BR> protected:<BR> virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support<BR> //}}AFX_VIRTUAL<BR>// Implementation<BR>protected:<BR> HICON m_hIcon;<BR> // Generated message map functions<BR> //{{AFX_MSG(CServerAsyncSocketDlg)<BR> virtual BOOL OnInitDialog();<BR> afx_msg void OnSysCommand(UINT nID, LPARAM lParam);<BR> afx_msg void OnPaint();<BR> afx_msg HCURSOR OnQueryDragIcon();<BR> afx_msg void OnBlisten();<BR> //}}AFX_MSG<BR> DECLARE_MESSAGE_MAP()<BR>};<BR>////ServerAsyncSocketDlg.cpp<BR>void CServerAsyncSocketDlg::OnBlisten() <BR>{<BR> UpdateData(true);<BR> if(!this->m_servesock.Create(m_iPort))<BR> { <BR> DWORD dwErr = CAsyncSocket::GetLastError(); <BR> return; <BR> } <BR> if(!this->m_servesock.Listen())<BR> { <BR> DWORD dwErr = CAsyncSocket::GetLastError(); <BR> return;<BR> } <BR>}<BR>
