Viewing screens of other clients on a network

Using VB can I view the screens of other clients on a network if I know their IP address.

Thanx

Know WinVNC? somebody wrote an extended version in VB (i got the source and i can tell u where to get it if u want) but this is for remote controlling (like Micro$ofts Remote Desktop) if you just want a screenshot, then u could do this with the "print-screen" key and send this thru a winsock connection, of course you could tell the programm to "press" the print-screen key, but the other guy has to have you program opened, you can't just get a screenshot without any remote prog.

thanx rockaway. where can i find the vb extensions
