Writing Memory

[=sinister=]

Ok, I really don't understand any of the read and write memory functions in AutoIt. It would be greatly appreciated if someone could write one for me or something? Here is all the information you will need:

Process Name: WoW.exe
Address: 8A1F04
Value To Write: 1

All I need is to write to that. Nothing else, no freezing or anything. It would be really appreciated if anyone could give me help in any way. Thanks.

I doubt that adress is the same for me as it was for you since i cant see any pointers, and i also doubt blizzard would not use like a gazzilion pointers.

Don't be so quick to judge, Jokke. I got that address from a friend. He told me to change the value to 1, and I would have a Mountain Climbing Hack, and it worked. Aslo worked for about a thousand others who tried it. But my objective is to get it to work in Autoit, automatically so the noobies won't have to do as much.

So, can anyone help me with this? Forgot to add that it is 4 byte.

I did some research, but couldn't find any functions for reading/writing to memory, except w0uters, but his way is way too confusing. I know the program called Syndrome written in AutoIt has a working one, unfortunatley i deleted the source code off my computer and edgeofnowhere deleted theirs too. >< any information and anything is appreciated now.. desperate for help..

Based off of W0uters. My own little spin off.
