Packet Sniffing

Can someone point me to the correct path to learn more about packet sniffing/sending? Or a few heads up on what I'm dealing with?

Mainly my goal is to open the Parka Shrine commission dialog from anywhere within Parka Shrine (but not limited to there).

how come you can't use ce for that? HUH? a good START is to scann unknown value and open dialog
then scan changed. then close dialog and scan changed
why cant it be an address? or even a pointer..

PS ive not tryed it, and its possible that it wont work but it is always worth a shot

go for the easy route.. unless u have an undetectable packet editor.
