取得IP地址的方法:     
    
  1、定义一个名为s_wsadata的结构,如下:   
    
      unsignedinteger           version   
    
      unsignedinteger           highversion   
    
      character                       discription[257]   
    
      character                       systemstatus[129]   
    
      unsignedinteger           maxsockets   
    
      unsignedinteger           maxupddg   
    
      string                             vendorinfo   
    
  二、在Local   External   Funtions中作如下的声明:   
    
        function   int   WSAStartup(   uint   UIVersionRequested,   ref   s_WSAData   lpWSAData   )     library   "wsock32.dll"   
    
          function   int   WSACleanup()   library   "wsock32.dll"   
    
          function   int   WSAGetLastError   (   )   library   "wsock32.dll"   
    
          function   int   gethostname   (   ref   string   name,   int   namelen   )   library   "wsock32.dll"   
    
          function   string   GetHost(string   lpszhost,   ref   blob   lpszaddress   )   library   "pbws32.dll"     
    
    
  三、使用方法:   
    
  s_wsadata                   l_WSAData   
    
  string ls_HostName   =   space(128)         
    
  string ls_IpAddress   
    
  int li_version   =   257   
    
  blob{4}   lb_hostaddress     
    
    
  IF   wsastartup   (   li_version,   l_WSAData   )   =   0   THEN   
    
  IF   gethostname   (   ls_HostName,   len(ls_HostName)   )   <   0   THEN   
    
  messagebox("GetHostName",WSAGetLastError())   
    
  ELSE   
    
    
  GetHost(ls_HostName,   lb_HostAddress)   
    
  ls_IpAddress   =   string(asc(string(blobmid(lb_HostAddress,1,1))),"000")   +   "."   
    
  ls_IpAddress   +=   string(asc(string(blobmid(lb_HostAddress,2,1))),"000")   +   "."   
    
  ls_IpAddress   +=   string(asc(string(blobmid(lb_HostAddress,3,1))),"000")   +   "."   
    
  ls_IpAddress   +=   string(asc(string(blobmid(lb_HostAddress,4,1))),"000")   
    
    
  END   IF   
    
    
  WSACleanup()   
    
  ELSE   
    
  messagebox("GetHostName",WSAGetLastError())   
    
  END   IF     
    
    
  messagebox('ls_hostname:   '+ls_hostname,'ls_ipaddress:   '+ls_ipaddress)
