editing mem

hey people

what do i do to edit memory in cod4 via console app when open and is it same as .dll way of editing memory?

thanks in advanced

[too vague] & no.

In a console app (assuming no dll injection!) you'd have to use Windows API like ReadProcessMemory (and WriteProcessMemory) to access the memory of another program. That's just how Windows(R) works. You have to use the API if you want to get access into another process's ram.

if by .dll you mean injection, then no:

When you "inject a dll", you're just putting code (byte code: 0's and 1's) into the process's memory and (optionally) running it.

Because the 'dll code' (aka. code located in the target* process's memory) is ...local to that process? and being run* by that process, the code is inherently different.

Pseudo-code to move the value 4 into the memory address 22446688:
console

Code:

WriteProcessMemory<Integer>(targetProcessHandle, 0x22446688, 4) // not the exact syntax <-- this is using windows API
//ask Windows to do the work

asm aka 'injected code', 'byte-code'

Code:

//code inside the process is all byte-code (ie. not in english, no functions names, etc, it's been compiled, it's 0's and 1's now)
//so the command might something* like.

mov eax, 4;
mov [22446688], eax ;//again, not the exact syntax. Will copy 4 into the memory address 22446688
//this is in target_app, so target_app is running it /doing the work.

-------
WriteProcessMemory<Integer>(targetProcessHandle, 0x22446688, 4)
this doesn't directly translated to byte code. Well, technically I guess it does, but.
----
When you are running injected code, you're dealing with byte-code, aka 0'1 and 1's, so all you have are cpu instructions and memory addresses. The target process is changing all the memory data for you.
When you use a 2nd app, you use the API and ask Windows nicely to manipulate/read the memory for you.

edit: some byte code

^^C++ has features related to asm, such as " __asm { }", but I'm not sure exactly.

WriteProcessMemory(0x26E17BDB, 0x90) would change the data in the memory box
and therefore the cpu instruction is changed. to 90. (nop: do nothing)
(assuming those boxes are run as code, as opposed to just being 'treated like data')

@abuckau907

i want to make it a external hack not to inject a dll and the code i have done wont edit the memory

does OpenProcess() return a valid handle?

I assume you're using ReadProcessmemory / WriteProcessmemory : is the problem your code, or the game? Does your code work with any* other game to modify memory?

@abuckau907

should i pm you the source? and im using WriteProcessMemory and the code dont give errors just wont edit memory

No, I don't have that game, so I wouldn't be able to test it very well. If there are no compile errors, idk. I'm not too good w/ C++, but if you have a more specific question I'll try to answer it.

"and the code dont give errors just wont edit memory"

Code:

if (!OpenProcess())
{
//error
}
..
if (!WriteProcessMemory())
{
//error
}

//Code in the error messages as you wish. "Unable to OpenProcess. Are you Admin?" , "Unable to WriteProcessMemory"

^^modify pinball.exe or calc.exe before you try a game which may have anti-cheat.
Make sure your code can work 100% of the time for an easy program. Then move on to a harder program.

I guess this thread is dead?

tip: Learn to program before you try to be m4jor h4xor.

Why are you asking questions about "dll hacking, etc" when you can't even get a menu system working? Why did I waste my time?
