FTP探索工具源代码,内涵测试以及详细说明。

主要代码如下：

void CPage1::OnStartSearch()     //开始
{

 m_avi.Play(0,-1,100);

 UpdateData();
 m_i=0; 
 m_nCur=0;   //当前正在测试的那个
 
 SetDlgItemText(IDC_STATE,"开始搜索了...");

 m_list.DeleteAllItems(); 
 CString str,strI; 
 DWORD addr1,addr2;              //初始化列表框显示
 m_StartIP.GetAddress(addr1);
 m_EndIP.GetAddress(addr2);  
 for(;addr1 <= addr2; addr1++)
 {
  m_tempIP.SetAddress(addr1);
  m_tempIP.GetWindowText(str);  
  strI.Format("%d",m_i);   
  m_i++;
  m_list.InsertItem(0,strI);
  m_list.SetItemText(0,1,str);
 }
 m_pp.SetRange(1,m_list.GetItemCount());
 m_pp.SetPos(1);

 if(this->m_bAutoStart)
 {
    if(m_list.GetItemCount() <= this->m_nThread)
    {
     for(int ij=0;ij    AfxBeginThread(AutoSearchThread,this);
    }
    else
    {
     for(int ii=0; ii< this->m_nThread;ii++)
      AfxBeginThread(AutoSearchThread,this);    
    }

 }

}
