[Help] Getting base adres from dll that changes

[mojo3nt]

Hello all, I am currently working on a alien swarm hack bud I am coming to a dead end.
Every time you start up the game, the base addresses change.

Lets say I want to write a value to the following address:
client.dll + 0x7F0F00

now take a look at the picture below…



see the dif betwean the 2 times I ran the game? client.dll base changes


I think im getting in the right direction by trying this piece of code I found on the forum:

void CAlienSwarmMojo3ntDlg::On_Button_Click() 
  {
          OpenProcessMemory();
   
          DWORD clientbase = NULL;
          clientbase = (DWORD)GetModuleHandle("client.dll");
   
          //clientbase to hex (getmodulehandle gives dec output)
   
          Writelong(clientbase + 0x7F0F00, 999);
  }

I wanted to test the piece of code, so I wrote a simple .dll that outputs the base to a message box and it worked! Yeah, another step closer.


Bud, keep in mind that I am NOT using .dll injection. I am trying to make a stand alone executable.




Hope that somebody can help me

One way is to use

CreateToolhelp32Snapshot

And loop through the modules.

I am sure you can find sample code all over the forum

//clientbase to hex (getmodulehandle gives dec output)

hex is just a different representation of the number, there is no converting needed.

Thank you GHOSTER, CreateToolhelp32Snapshot really helped me. i got it working right now

also thanks to learn_more, now i understand why i am putting 0x before a hexadecimal number. pretty simple
