[help]How to change the value

[258456]

Ok, so how do i change the value of an address? Well, more clearly, when i am using WriteProcessMemory(), i don't know what to do. Like from cheat engine i got the address, and the value in hexadecimal form. Just show me how to input the info. Like here is some info: adress: 0x01564F9 value: 0x2165482

How do i put those in the parmeters of WriteProcessMemory(), thanks in advance.

The address and the value are in hex format?

Anyways, to use writeprocessmemory first thing you need to do is get the Window Handle for the target

HWND hwnd = FindWindow(NULL,"Name of Window");

secondly you need the process id to find the process handle. For this we use

DWORD pid;
GetWindowThreadProcessId(hwnd, &pid);

Lastly we use the process id to find the process handle, we can pass that to WriteProcessMemory

HANDLE hProc = OpenProcess(PROCESS_ALL_ACCESS,false,pid);

Now, hProc is our process handle so we can do:

WriteProcessMemory(hProc,(LPVOID)0x01564F9,(LPCVOID)<value you are writing>,sizeof(int),NULL);

You will need to include windows.h now if you can't figure out how to put this into a proper hack you should be reading a book.

Lol lilneo thanks I already knew all that stuff but the writeprocess memory helped thanks a lot man.

Just another question for the third parameter which is the value I want to write should it be a hex or normal number?

MSDN is your friend when your coding.

/ why would you set hex as the value ? why not just use float,byte or 4byte /

You can write it in anything you want. It's just a number/data.

here is my code, it won't write the memory and idk wat's wrong.

#include <iostream>
#include <Windows.h>
int main()
{
	HWND game = FindWindow(NULL, TEXT("Catapult Madness | Armor Games - Windows Internet Explorer"));
	DWORD pid;
	
	GetWindowThreadProcessId(game, &pid);
	
	HANDLE hproc = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);
	std::cout<<pid<<std::endl;
	
	if(WriteProcessMemory(hproc, (LPVOID) 0x0EBF071C, (LPCVOID) 0, sizeof(4), NULL)){
		MessageBox(NULL, TEXT("Memory Copied."), TEXT("Hack"), NULL);
	}
	if(!WriteProcessMemory(hproc, (LPVOID) 0x0EBF071C, (LPCVOID) 0, sizeof(4), NULL)){
		MessageBox(NULL, TEXT("Failure"), TEXT("Hack"), NULL);
	}
	
	std::cin.get();
	return 0;
}

	DWORD pid;
	
	GetWindowThreadProcessId(game, &pid);
	
	HANDLE hproc = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);
	std::cout<<pid<<std::endl;

        int Zero = 0;
	
	if(WriteProcessMemory(hproc, (LPVOID) 0x0EBF071C, (LPCVOID) &Zero, sizeof(int), NULL)){
		MessageBox(NULL, TEXT("Memory Copied."), TEXT("Hack"), NULL);
	}
	if(!WriteProcessMemory(hproc, (LPVOID) 0x0EBF071C, (LPCVOID) &Zero, sizeof(int), NULL)){
		MessageBox(NULL, TEXT("Failure"), TEXT("Hack"), NULL);
	}
	
	std::cin.get();
	return 0;
}

thanks i will see if it works and get back to you

EDIT: __________________________________________________ ___--
ok, so i tried that code and it didn't work, it's basically like my code, idk y it's not writing to the address. Has anybody had a problem like this? I am running Win7

[Void]

OpenProcess error in Windows XP?

[php]
HANDLE hProc = OpenProcess(PROCESS_VM_OPERATION | PROCESS_VM_WRITE,0,ProcessId);

void, thanks so much it worked!!!
