分享VS2010 MFC IP地址控件 connect使用
MFC IP地址变量类型设定了DWORD类型，使用connect时出现问题，
(!m_ClientSocket->Connect(m_IP,m_EDITport))
BOOL CAsyncSocket::Connect(LPCTSTR,UINT)”: 不能将参数 1 从“CIPAddressCtrl”转换为“LPCTSTR”
用—T（“”）可以解决，但是执行程序时，不能连接。
大家有解决的办法吗？初学，希望大家帮助！

按着您的方法，问题解决了。
我是用CSOCKET做的TCP程序，现在想发送十六进制的数据，是在SEND函数里添加就可以了是吧？
这是发送函数，您帮忙看下，是从网上拷的一段
void CtestDlg::OnBnClickedBtnsend()
{
// TODO: 在此添加控件通知处理程序代码
if (m_arOut)
{
if (m_stats==0)
{
UpdateData(true);
*m_arOut<<m_EDITsend;
m_arOut->Flush(); xianzai
}
else
{
UpdateData(true);
*m_arOut<<m_EDITsend;
m_arOut->Flush();
}
}
else AfxMessageBox(_T("Not connected!"));
}
void CtestDlg::OnAccept()
{
m_connect+="OK!";
UpdateData(false);
m_ClientSocket=new MySocket;
m_ClientSocket->GetDlg(this);
m_ServerSocket->Accept(*m_ClientSocket);
m_ClientSocket->m_stats=m_ServerSocket->m_stats;
m_file=new CSocketFile(m_ClientSocket);
m_arIn=new CArchive(m_file, CArchive::load);
m_arOut=new CArchive(m_file, CArchive::store);
}
//读出网络缓冲区中的数据包
void CtestDlg::OnReceive()
{
//*m_arIn>>m_Input;
//UpdateData(FALSE);
BYTE cbDataBuffer[1024],i=0;
memset(cbDataBuffer,0,sizeof(cbDataBuffer));
int ret = m_ClientSocket->Receive(cbDataBuffer,1024);
if (ret <= 0)
{
MessageBox(_T("接受数据不大于零！"));
}
else
{
m_EDITrx += CString(cbDataBuffer);
UpdateData(FALSE);
//MessageBox("完美接受数据！");
}
}
void CtestDlg::OnClose()
{
if (m_ClientSocket->m_stats==0)
m_connect="Client ";
else
m_connect="Server ";
m_connect+="has disconnected!";
UpdateData(false);
}

说明错了，IP是control 类型，不是DWORD类型

SetDlgItemText(IDC_IPADDR,"192.168.50.1");

还是不行，帮忙看下代码：
CString str1;
CString str;
m_IP.GetWindowTextA(str1);
UpdateData(true);
if (m_stats==0 ) //server
{
if (m_ServerSocket)
{
//MessageBox(_T("WindowsSocket initial failed!","Connect",MB_ICONSTOP));
MessageBox(_T("WindowsSocket initial succeed!","Connect",MB_ICONSTOP));
m_connect="Connected!";
GetDlgItem(IDC_BTNsend)->EnableWindow(true);
GetDlgItem(IDC_BTNdis)->EnableWindow(true);
GetDlgItem(IDC_BTNconnect)->EnableWindow(false);
GetDlgItem(IDC_EDITport)->EnableWindow(false);
GetDlgItem(IDC_IP)->EnableWindow(false);
UpdateData(false);
}
else
{
m_connect="Waiting for Client...";
UpdateData(false);
if(!AfxSocketInit())
{
MessageBox(_T("WindowsSocket initial failed!","Send",MB_ICONSTOP));
return;
}
m_ServerSocket = new MySocket;
m_ServerSocket->m_stats = m_stats;
m_ServerSocket->GetDlg(this);
if (!m_ServerSocket->Create(m_EDITport))
{
MessageBox(_T("WindowsSocket Create failed!","Send",MB_ICONSTOP));
}
else
m_ServerSocket->Listen();
}
}
else
{
if (m_stats==1)//Client
{
if(m_ClientSocket)
{
// MessageBox(_T("WindowsSocket initial succeed!","Connect",MB_ICONSTOP));
m_connect="Connected!";
GetDlgItem(IDC_BTNsend)->EnableWindow(true);
GetDlgItem(IDC_BTNdis)->EnableWindow(true);
GetDlgItem(IDC_BTNconnect)->EnableWindow(false);
GetDlgItem(IDC_EDITport)->EnableWindow(false);
GetDlgItem(IDC_IP)->EnableWindow(false);
UpdateData(false);
}
else
{
m_connect="Connect to the Server...";
UpdateData(false);
if (!AfxSocketInit())
{
MessageBox(_T("WindowsSocket initial failed!","Receive",MB_ICONSTOP));
return;
}
m_ClientSocket = new MySocket;
m_ClientSocket->GetDlg(this);
m_ClientSocket->m_stats=m_stats;
if(!m_ClientSocket->Create())
{
MessageBox(_T("WindowsSocket create failed!","Receive",MB_ICONSTOP));
return;
}
else
{
//if (!m_ClientSocket->Connect(str,m_EDITport))
if (!m_ClientSocket->Connect(str1,m_EDITport))
{
CString str = m_connect;
SocketReset();
m_connect=str;
m_connect+="Error!";
UpdateData(false);
}
else

}
UpdateData(false);
}
}
}
}
if (m_stats==-1)
{
m_connect="Please choose the status!";
AfxMessageBox(m_connect);
//msg="Please choose the status!";
//AfxMessageBox(msg);
}
}

设置成CIPAddressCtrl类型，然后调用GetWindowTextA来获得对应的IP地址
