VB and HEX Address finder

[Gencast]

Hello everyone I have this tool i made. It's more like a Runner. It runs certain .EXE files for a Game. Now this game as about 5 Different Servers that means it needs to have 5 different buttons to run what even .EXE file.

Now i got a request and it was if i could add a IP changer to the tool. Now the only way i know how to edit the IP on the games .EXE file is via a HEX tool. sense that is the case I need to make my tool search and specific address on the HEX decimal of the .EXE. This way i Can make a texbox where they can just type in the IP address of the server they want to play in and have it save. This will save time and space, sense i can reduce the 5 .EXE files to 2 or 3 .EXE files

So the question is What are the codes i need and what do I need to do to make this happen?
