So, you need a way to get your user local IP address? Here is the winsock way.
Drop a Button and two Labels then add the bellow code on your window events:

C++:

#include <System.hpp>
#include <Winsock2.h>
//-----------------------------------------------------------------
void __fastcall TForm1::FormCreate(TObject *Sender)
{
WORD wVersionRequested;
WSAData wsaData;
wVersionRequested = MAKEWORD(1,1);
WSAStartup(wVersionRequested,&wsaData);
}
//-----------------------------------------------------------------
void __fastcall TForm1::Button1Click(TObject *Sender)
{
char Buf[256]={0};
hostent *p=gethostbyname(Buf);
//user ip
Label1->Caption=(inet_ntoa)(*((in_addr*)p->h_addr_list[0]));
//user computer name
Label2->Caption=p->h_name;
}
//-----------------------------------------------------------------
void __fastcall TForm1::FormDestroy(TObject *Sender)
{
WSACleanup;
}
//-----------------------------------------------------------------
