以下这个程序可以得到本机IP地址和计算机名:
uses Winsock;
... ...
procedure TForm1.FormCreate(Sender: TObject);
var
wVersionRequested : WORD;
wsaData : TWSAData;
begin
{Start up WinSock}
wVersionRequested := MAKEWORD(1, 1);
WSAStartup(wVersionRequested, wsaData);
end;
procedure TForm1.Button1Click(Sender: TObject);
var
p : PHostEnt;
s : array[0..128] of char;
p2 : pchar;
begin
{获得计算机名}
GetHostName(@s, 128);
p := GetHostByName(@s);
Memo1.Lines.Add(p^.h_Name);
{获得本机的ip地址}
p2 := iNet_ntoa(PInAddr(p^.h_addr_list^)^);
Memo1.Lines.Add(p2);
end;
procedure TForm1.FormDestroy(Sender: TObject);
begin
{Shut down WinSock}
WSACleanup;
end;
