Question:
How do I get the local internet machine name and IP address?
Answer:
Getting the local machine name and IP address is a straight
forward process that is most easily accomplished using the TCP
component. Simply drop a TCP component from the internet page
of the component palette on to a form, and access the following
members of the TCP component:
Memo1.Lines.Add(TCP1.LocalHostName);
Memo1.Lines.Add(TCP1.LocalIp);
If you prefer not to use the TCP component, here is an example
that interfaces directly with your winsock layer:
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
{Get the computer name}
GetHostName(@s, 128);
p := GetHostByName(@s);
Memo1.Lines.Add(p^.h_Name);
{Get the IpAddress}
p2 := iNet_ntoa(PInAddr(p^.h_addr_list^)^);
Memo1.Lines.Add(p2);
end;
procedure TForm1.FormDestroy(Sender: TObject);
begin
{Shut down WinSock}
WSACleanup;
end;
