I currently working on a memory scanner and have been searching around and cant seem to find any solution to my problem, most examples i have seen uses the same "solution" as i do in the script below

The issue i have is that when i try to list all modules and i always get incorrect "EndAddress" aka size of the main .exe. however all the dlls lists just fine.

Anyone have any tips on how to solve this? (tried GetModuleInformation also, same result)

Code:

function GetModuleInfo(pID:integer; Module:string; out BaseAddy:integer; out EndAddy:integer):boolean;
var
  SnapShot:tHandle;
  GetModuleInfo:tModuleEntry32;
  NotLastModule:boolean;
begin
  result := false;
  BaseAddy := 0;
  EndAddy := 0;

  SnapShot := CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, pID);
  GetModuleInfo.dwSize := SizeOf(GetModuleInfo);

  NotLastModule := Module32First(SnapShot, GetModuleInfo);

  while NotLastModule = true do begin

    if (GetModuleInfo.szModule = Module) then begin
      result := true;
      BaseAddy := integer(GetModuleInfo.modBaseAddr);
      EndAddy := integer(GetModuleInfo.modBaseAddr)+ GetModuleInfo.modBaseSize;
      break;
    end;

    NotLastModule := Module32Next(SnapShot, GetModuleInfo);
  end;

  CloseHandle(SnapShot);
end;


PlantsVsZombies.exe should end at 00815000 (which CE states in the memory regions table) yet i always get 00628000 (Have used this methode and GetModuleInformation)

repeat "however all the dlls lists just fine"

Code:

00400000
00628000
PlantsVsZombies.exe
C:\Program Files\Plants vs Zombies\PlantsVsZombies.exe

77910000
77AAC000
ntdll.dll
C:\Windows\SYSTEM32\ntdll.dll

75D90000
75E70000
KERNEL32.DLL
C:\Windows\System32\KERNEL32.DLL

75B40000
75D3A000
KERNELBASE.dll
C:\Windows\System32\KERNELBASE.dll

6A510000
6A5AC000
apphelp.dll
C:\Windows\SYSTEM32\apphelp.dll

759A0000
75B39000
USER32.dll
C:\Windows\System32\USER32.dll

75020000
75037000
win32u.dll
C:\Windows\System32\win32u.dll


My guess? is that the game is packed and gets unpacked and the ModuleSize is just a value set when its allocated into memory the first time? anyway i guess there is a cleaver way of doing this and i hope someone could give me some help.

The size you are getting from that API is not going to account for all the custom regions that are allocated by the process and such. You are only getting the size of the module itself. If you want to get all the regions of the process, you need to enumerate them with something such as VirtualQuery/VirtualQueryEx.
