Write Process Memory in VB.NET (Visual Studio 2010)

Question

I am trying to edit the process memory of a game (Age Of Empires II: The Conquerers). I can edit the memory manually on TSearch and it works just fine. I want to this with VB.NET but have had no luck. Note: I am not doing this to cheat, I am just using this as a learning experience for changing process memory.

Process Memory info:

Process Name : age2_x1.Exe

Address : FB1DD90

Type :Float

Current Value : 19. <--Note that the period (.) IS included in the value.

Wanted Value : 25.

I have tried TONS of stuff on vb.net with no luck. If you can help me at all that would be awesome. StackOverflow has never let me down! Thanks guys!

Answer 1

Visual Basic is a rather odd choice for this sort of thing. However, you can use P/Invoke to call the Windows API functions directly.

It's fairly straightforward: OpenProcess and request PROCESS_VM_WRITE permissions, then use WriteProcessMemory to make your modifications. Obviously this is all rather dangerous and you must be absolutely sure you know what you are doing, as a tiny mistake could completely corrupt the state of the other process, causing it to crash--or much worse!
