用黑客扫描工具

我根据访问别人机器上的注册表可获得，但太慢。

我想自己编程实现

[路人丁]

//根据ip获取主机名
struct hostent *hostname;
unsigned int addr;
addr=inet_addr((char FAR*)(Edit1->Text.c_str()));
hostname=gethostbyaddr((char *)&addr,4,AF_INET);
Edit2->Text=AnsiString(hostname->h_name);

//根据主机名获取ip地址
struct hostent *hostname;
struct in_addr in;
char *IP,*ptr;
if(!(hostname=gethostbyname((char FAR*)(Edit3->Text.c_str()))))
{
Application->MessageBox("错误","出错信息",MB_OKCANCEL);
return;
}
memset((void *)&in,sizeof(in),0);
in.s_addr=*((unsigned long *)hostname->h_addr_list[0]);
if(!(ptr=inet_ntoa(in)))
return;
IP=new char[strlen(ptr)+1];
strcpy(IP,ptr);
Edit4->Text=AnsiString(IP);

什么？！
别人机器上的登陆用户？

如何获得？

我也想知道，帮你up

有人知道吗？知道了，就说！我也给分！给好多份！！！！
200够不够？

顺便up!!

看看这个行不行？事先建一个空连接。
