vc List控件保存socket

插入上线信息时保存

m_IpList.SetItemData(标识,(DWORD)MyClientSocket);//保存服务SOCKET句柄

当双击List控件的时候取出socket

void CMyClientOnlineDlg::OnClickList(NMHDR* pNMHDR, LRESULT* pResult) 

{

        int m_index;

DWORD val;

SOCKET m_socket;

POSITION pos = m_IpList.GetFirstSelectedItemPosition();

m_index = m_IpList.GetNextSelectedItem(pos);

if (m_index ==-1)

{

MessageBox("ÇëÑ¡Ôñһ̨ÉÏÏßÖ÷»ú!","Ìáʾ",MB_ICONINFORMATION);

return;

}

       val =m_IpList.GetItemData(m_index);

       m_socket = (SOCKET)val;

       if(send(m_socket,0,0,0)==SOCKET_ERROR) return;

    *pResult = 0;

}
