I need some help...

[CantShutMyMouth]

Hello. I modified a value of a memory of a process but with a console application...
now i'm trying to do it with a dll...
What's wrong here?

PHP Code:

#include <windows.h>
#include <iostream> 
using namespace std;
int main() 

BOOLEAN WINAPI DllMain( IN HINSTANCE hDllHandle, 
         IN DWORD     nReason, 
         IN LPVOID    Reserved )

{
;
DWORD Id;
HANDLE ProcessHandle;
int value; 
    unsigned adress = 0x07A4F60;     
      switch ( nReason )
   {
    case DLL_PROCESS_ATTACH:
    DWORD WINAPI GetCurrentProcessId(Id);
    ProcessHandle = OpenProcess(PROCESS_VM_WRITE |PROCESS_VM_OPERATION ,false,Id);
    value=1967458304;
    fflush(stdin);
    WriteProcessMemory(ProcessHandle,(LPVOID)adress,&value,sizeof(int),NULL);
    break;
      }
      
         }

I think your memory address is not static looks like you need a pointer

If i understand what you understand by " static" word, then... I closed the game and used this adress and still worked. wherever and whenever
Else, be more understoodable ( i'm a begginer, sol et me read about pointers in my book ) )


EDIT... Eror:

--------------------Configuration: test1 - Debug--------------------
Compiling source file(s)...
test1.cpp
test1.cpp: In function `int main()':
test1.cpp:6: error: syntax error before `__attribute__'
test1.cpp: In function `BOOLEAN DllMain(HINSTANCE__*, long unsigned int, void*)

NEW ERROR:, after i eliminated the paramter ( ID) from GetCurrentProcessID:

First learn C++ before you try to do ANYTHING with C++.

[schneider1424]

delin he a begginer how he learn without doing anything in C++
+ He need help so help or dont say **** like learn c++ 1st when he already learning it

[Delinquenz]

He should use a book.. this code is awful.

Sorry for my bad sound, but why do you want to hack, if your knowledge isn't so wide?

Why?

PHP Code:

int main() 


Just look at your code formatting..

Maybe this () is your solution.

instead of this

PHP Code:

DWORD WINAPI GetCurrentProcessId(Id); 


maybe this (idk if this works)

PHP Code:

Id = GetCurrentProcessId(); 


But why do you inject a dll to open a process?

Thanks for trying to help me. Actually, i changed that memory by console application so:

 Spoiler

#include <windows.h>
#include <iostream>
using namespace std;
int main()
{
;
DWORD Id;
HANDLE ProcessHandle;
int value;
unsigned adress = 0x07A4F60;
GetWindowThreadProcessId(FindWindow(0,"Client"),&I d);
cout << Id << endl;
ProcessHandle = OpenProcess(PROCESS_VM_WRITE |PROCESS_VM_OPERATION ,false,Id);
cout << "ProcessHandle: " << ProcessHandle << endl;
value=1967458304;
fflush(stdin);
WriteProcessMemory(ProcessHandle,(LPVOID)adress,&v alue,sizeof(int),NULL);


}

but i'm trying with dlls, because the game may have other process names, so i need to get it's id by injecting dll. and i'd like that dll to change the memory , too.


But the problem is at the switch( nReason) .... even if i used it as microsoft says,it still doesn't works...


Thanks anyway
And thanks "schneider1424" too for supporting me

I'm not used to inject DLLs but if you inject the DLL you just have to find out your actual process handle, or am I wrong?

[CantShutMyMouth]

#include <windows.h>
#include <iostream>
using namespace std;
void dll()

{

DWORD Id;
HANDLE ProcessHandle;
int value;
unsigned adress = 0x07A4F60;
Id = GetCurrentProcessId();
ProcessHandle = OpenProcess(PROCESS_VM_WRITE |PROCESS_VM_OPERATION ,false,Id);
value=1967458304;
fflush(stdin);
WriteProcessMemory(ProcessHandle,(LPVOID)adress,&v alue,sizeof(int),NULL);

}

It has no error when compiling it.. but still doesn't modfiy that value :|

Ehm, so you're in the process, right?

The lazy way:
unsigned long *adr = (unsigned long *)0x07A4F60;
*adr = value;

You don't need to use OpenProcess when your dll is injected (as far as I know).

That's what I mean, sorry for my bad English.

Thank you so much, your method worked :X
