Re^3: Interprocess communication in windows xp

In other words, you didn't write Application.exe and cannot modify it.

That may present some challenges depending on if and how well the socket interface is documented. Presumably, it is running as a server. You need to determine how the protocol it uses works; if there is no documentation for this you must do it by observing it interact with whatever client it was intended to work with. That means eavesdropping on the connection with something like wireshark.
