Ok, I'm making a simple dll that will "freeze" these addresses when a key is pressed. All the addresses are pointers. Here's the header file and the cpp file:

Code:
#ifndef Speed
#define Speed
#define WIN32_LEAN_AND_MEAN

#include <windows.h>
#include <string.h>
#include <stdio.h>

unsigned long Weight = *(unsigned long*)((*(unsigned long*)0x89af6c)+0x44);
unsigned long BoosterSpeed = *(unsigned long*)((*(unsigned long*)0x89af58)+0x604);
unsigned long BoosterTime = *(unsigned long*)((*(unsigned long*)0x89af58)+0x960);
unsigned long MinSpeed = *(unsigned long*)((*(unsigned long*)0x89af58)+0x600);
unsigned long MaxSpeed = *(unsigned long*)((*(unsigned long*)0x89af58)+0x5fc);
int newvalue = 999;
int newvalue2 = 0;
int newvalue3 = 5000;
int onoff1 = 1;
int onoff2 = 1;

unsigned long nWeight = *(unsigned long*)((*(unsigned long*)0x89af6c)+0x44);
unsigned long nBoosterSpeed = *(unsigned long*)((*(unsigned long*)0x89af58)+0x604);
unsigned long nBoosterTime = *(unsigned long*)((*(unsigned long*)0x89af58)+0x960);
unsigned long nMinSpeed = *(unsigned long*)((*(unsigned long*)0x89af58)+0x600);
unsigned long nMaxSpeed = *(unsigned long*)((*(unsigned long*)0x89af58)+0x5fc);
#endif


The .cpp file:

Code:
#include "Speeder.h"

DWORD WINAPI KeyDetection(LPVOID lpParam);

BOOL APIENTRY DLLMain(HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)

{
   if (ul_reason_for_call == DLL_PROCESS_ATTACH)
   {
      CreateThread(0,0,(LPTHREAD_START_ROUTINE)&KeyDetection,0,0,0);
   }
   return true;
}
   
DWORD WINAPI KeyDetection(LPVOID lpParam)
{

   for(;;)
   {
      Sleep(100);
      if(GetAsyncKeyState(VK_F10))
      {   

         if (onoff1==1)
         {
         memcpy((void*)Weight,(void*)newvalue2,sizeof(Weight));
         memcpy((void*)BoosterSpeed,(void*)newvalue,sizeof(BoosterSpeed));
         memcpy((void*)BoosterTime,(void*)newvalue,sizeof(BoosterTime));
         memcpy((void*)MinSpeed,(void*)newvalue2,sizeof(MinSpeed));
         memcpy((void*)MaxSpeed,(void*)newvalue,sizeof(MaxSpeed));
         onoff1 = 0;
         }
         else if(onoff1==0)
         {
            memcpy((void*)Weight,(void*)nWeight,sizeof(Weight));
            memcpy((void*)BoosterSpeed,(void*)nBoosterSpeed,sizeof(BoosterSpeed));
            memcpy((void*)BoosterTime,(void*)nBoosterTime,sizeof(BoosterTime));
            memcpy((void*)MinSpeed,(void*)nMinSpeed,sizeof(MinSpeed));
            memcpy((void*)MaxSpeed,(void*)nMaxSpeed,sizeof(MaxSpeed));
            onoff1 = 1;
         }
      }

      if(GetAsyncKeyState(VK_F11))
      {
         if(onoff2==1)
         {
            memcpy((void*)MaxSpeed,(void*)newvalue3,sizeof(MaxSpeed));
            onoff2 = 0;
         }
         else if(onoff2==0)
         {
            memcpy((void*)MaxSpeed,(void*)nMaxSpeed,sizeof(MaxSpeed));
            onoff2 = 1;
         }
         Sleep(100);
      }
      
   return TRUE;
}


I inject it and press f10 but nothing happens.

Check if your DLL was injected successfuly and that its looping.

Also, instead of GetAsyncKeyState, use RegisterHotKey, then you don't have to loop.

This will only set it once when you press the hotkey. In order to freeze, you have to continuously right to that address.

Will register hotkey work if you don't make a window? And you'd still have to loop Getmessage, right? (Never used registerhotkey)

Okay, I think the problem is that the dll is not getting injected (I put a messagebox before the createthread). Can anyone see why?

I prefer making a window, instead of just using hotkeys to activate.

And it would be easier just to nop whatever writes to this address - find out using CE.

I don't think messagebox works in dllmain. Try putting it in your actual thread.
See http://msdn.microsoft.com/en-us/library/ms682583.aspx for details.

I tried injecting it into notepad, and it failed, but when I inject into my game, it works. Thanks for all the help so far.
