 |

I remember seeing some tutorials for making trainers, but I didn't know how to program then.
I'm looking for something in c# with VS.

| You want to change memory? Use WriteProcessMemory() api for that. |

And...
| Code: | using System.Diagnostics;
using System.Runtime.InteropServices;
OpenProcess()
VirtualProtectEx()
CloseHandle() |
PInvoke can help you a lot. |

It can also be done without using
OpenProcess()
VirtualProtectEx()
CloseHandle()
I only use
WriteProcessMemory
ReadProcessMemory

Why not use the correct way?...
By the way, how do you establish the access to the handle of the process?... to my knowledge, if you don't set the correct access (PROCESS_VM_WRITE or PROCESS_VM_READ) you couldn't read/write memory (If the chunk of memory haven't read/write access). |

OpenProcess / CloseHandle aren't absolutely needed in .NET except for extreme conditions with some applications. The Process class exposes a handle for you that you can use rather then needing API or worrying about closing the handle yourself.
Assuming you are using VS2010, you can use Linq for making queries easy on the running processes for example:
| Code: |
Process p = (from Process proc in Process.GetProcessesByName("winmine")
select proc).FirstOrDefault();
if (p != null)
{
// Do stuff with our process here..
// p.Handle for anything that requires a
// process handle to be used.
}
|
Then for example if you need a base address from this process for something like, 'winmine.exe'+15123, you can do:
| Code: |
Process p = (from Process proc in Process.GetProcessesByName("winmine")
select proc).FirstOrDefault();
if (p != null)
{
IntPtr lpBaseAddress = (from ProcessModule mod in p.Modules
where mod.ModuleName == "winmine.exe"
select mod.BaseAddress).SingleOrDefault();
}
|
And so on, then you can just use pinvoke for ReadProcessMemory/WriteProcessMemory.

Blame Wiccaan, he converted me ages ago. At one point i did use these api's but iv not had many problems since, except for those rare occasions.
Alot less code needed, and when i find cleaner ways of coding, i stick with it.

Woah. A little more info than that please. I have no idea which memory I need to edit. How do I find the location of the variables? How did you guys learn this stuff?

Start use the CE...
Do the CE Tutorial, and then go modify the memory of some game.
You must not run if you can't walk. |
