Writing to an Output Socket in use by another program

Hi, is there any way possible for one program to send data through a socket being used by another program?

You would probably get more help in the Network/Device Communication board.

well, since you can't access the memory from another process, you would need to write a windows hook DLL and inject it into that running process, then you could do calls on that socket handle.

What if the socket is created by a Java applet running in a web browser?

then you're screwed.
