[HELP] trying to do dll injection for the first time!

[Shutzler]

Okey, i have made 2 applications:

1x C# injector (i read that it was possible)
1x C dll file

Now, im trying to hack minesweeper(since im a noob and all). My C# application is the one doing the injection to the process MineSweeper.exe, i think its working, so i would like someone to comment my C dll please.

DLLfile:

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

DWORD ThreadID;
int *mine1  = (int*)0x1F6C84C;    //Offset for score1
int *mine2  = (int*)0x4485E8;    //Offset for score1

DWORD WINAPI changeTime(LPVOID lParam) {
      while(1)
	  {
              *mine1 = 66;
			  *mine2 = 66;
	  }
              
      ExitThread(0);
}

BOOL APIENTRY DllMain (HINSTANCE hInst     /* Library instance handle. */ ,
                       DWORD reason        /* Reason this function is being called. */ ,
                       LPVOID reserved     /* Not used. */ )
{
    if(reason == DLL_PROCESS_ATTACH) 
	{
		MessageBox(*(new HWND), LPWSTR("Dll Injection Successful! "), LPWSTR("Dll Injector"), MB_ICONEXCLAMATION | MB_OK);

        CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)&changeTime, 0, 0, &ThreadID);
	}

    return TRUE;
}

Reason why i have 2 of the *mine (mine1 and mine2) is that i used TSearch on Minesweeper application and found that both of them yield the count on total mineflags left. (im trying to edit the number to 66 as you can see)

Don't directly cast to LPTHREAD_START_ROUTINE. Bad news for x64 folks. Don't create a msgbox in dllmain either.

Also. One of those addresses looks like it would be in the .code section.

Will it not work then?

tryed:

BOOL APIENTRY DllMain (HINSTANCE hInst     /* Library instance handle. */ ,
                       DWORD reason        /* Reason this function is being called. */ ,
                       LPVOID reserved     /* Not used. */ )
{
	MessageBox(0, LPWSTR("TEST"), LPWSTR("TEST"), MB_ICONEXCLAMATION | MB_OK);
...
...

The messagebox(straight after DllMain) does not show up! (then i think its not loaded... or?)

Create the messagebox inside the thread you create. Just make your thread function the correct way and you don't have to cast to LPTHREAD_START_ROUTINE. It's on MSDN.

Tried to google it but i cant seem to find the example/page you are reffering to... if its not to much, could you write the code(just copy paste)/edit my code to what you would have written?

It is my first C code ever!

You're retarded for trying to hack games without even knowing how to program in C.
