Question:
At client, how can I get the IP address or host name of
itself.

Answer:
The following example requires using the Winsock API
encapsulated in WinSock.pas.

uses
WinSock;

procedure GetHostInfo(var Name, Address: string);
var
WSAData: TWSAData;
HostEnt: PHostEnt;
begin
{ no error checking...}
WSAStartup(2, WSAData);
SetLength(Name, 255);
Gethostname(PChar(Name), 255);
SetLength(Name, StrLen(PChar(Name)));
HostEnt := gethostbyname(PChar(Name));
with HostEnt^ do
Address := Format('%d.%d.%d.%d',[
Byte(h_addr^[0]),
Byte(h_addr^[1]),
Byte(h_addr^[2]),
Byte(h_addr^[3])]);
WSACleanup;
end;
