Title: Only 16K for getting IP !!!
Question: I found an application (20K) on a magazine that discovers the machine IP and in the article was written that it's hard to reduce the size of a so complex application... just compile this:
Answer:
Put this code into a Console Application:
Program MyIP;
{$APPTYPE CONSOLE}
Uses
WinSock;
Var
wsaData : TWSAData;
Begin
WSAStartup( 257, wsaData );
WriteLn( 'Host: ', GetHostByName( NIL )^.h_name );
Write ( 'IP : ', iNet_ntoa( PInAddr( GetHostByName( NIL )^.h_addr_list^ )^ ) );
WSACleanup;
End.
Then compile it. The resulting EXE file will be 16.834 bytes.
And if you compress it with tools like UPX 1.07w, it will be reduced by 59%, resulting EXE files will be only 9.728 bytes !!!
(The correct file size for the competition is 16.384)
Can anyone do better?
