HP auslesen / Read HP[C++]

[jackicola]

Hi!
Ich versuche momentan nur zum Spaß in Aion meine Max-HP auszulesen.
Sieht bis jetzt so aus (Ausschnitt):

if(hGameWindow)
{
GetWindowThreadProcessId(hGameWindow, &dwProcId);
				if(dwProcId != 0)
				{
					hProcHandle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcId);
					if(hProcHandle == INVALID_HANDLE_VALUE || hProcHandle == NULL)
					{
						GameStatus = "Failed to open Process!";
						std::cout << GameStatus << std::endl;
						std::cout << GetLastError();
					}
				} else {
					GameStatus = "Failed to get Process ID!";
					std::cout << GameStatus << std::endl;
					std::cout << GetLastError();
				}
			}


....
....
ReadProcessMemory(hProcHandle, (LPCVOID)health/*DWORD health=0xA2771C;*/, &iHealth, sizeof(int), NULL);

Funktioniert aber so nicht. Nach ein bisschen googlen habe ich herrausgefunden dass es da noch etwas mit der Game.dll auf sich hat, aber was genau muss ich noch tun damit es funktioniert? BTW: ReadProcessMemory gibt 0 zurück, GetLastError 299.

Hi!
At the moment I'm trying to read my Max-HP via ReadProcessMemory.
Looks like this(excerpt):

if(hGameWindow)
			{
				GetWindowThreadProcessId(hGameWindow, &dwProcId);
				if(dwProcId != 0)
				{
					hProcHandle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcId);
					if(hProcHandle == INVALID_HANDLE_VALUE || hProcHandle == NULL)
					{
						GameStatus = "Failed to open Process!";
						std::cout << GameStatus << std::endl;
						std::cout << GetLastError();
					}
				} else {
					GameStatus = "Failed to get Process ID!";
					std::cout << GameStatus << std::endl;
					std::cout << GetLastError();
				}
			}


....
....
ReadProcessMemory(hProcHandle, (LPCVOID)health/*DWORD health=0xA2771C;*/, &iHealth, sizeof(int), NULL);

But it doesn't work like this. I found out that I have to do something with Game.dll, but what? BTW: ReadProcessMemory returns 0, GetLastError 299.


Greets!

For the base address ("Game.dll"), look into WINAPI's GetModuleBase. You must add that to the offset -- currently 0xCCAE74 on retail.

I didn't find a function called GetModuleBase, ich just found GetModuleHandle.. is that ok?

You want the Base Address, not a Handle; it is NOT the same and NOT ok. It looks like C++ doesn't support GetModuleBase but you can easily iterate over the modules and create it:

    DWORD GetModuleBase(LPSTR lpModuleName, DWORD dwProcessId)
    {
    MODULEENTRY32 lpModuleEntry = {0};
    HANDLE hSnapShot = CreateToolhelp32Snapshot( TH32CS_SNAPMODULE, dwProcessId );
    if(!hSnapShot)
    return NULL;
    lpModuleEntry.dwSize = sizeof(lpModuleEntry);
    BOOL bModule = Module32First( hSnapShot, &lpModuleEntry );
    while(bModule)
    {
    if(!strcmp( lpModuleEntry.szModule, lpModuleName ) )
    {
    CloseHandle( hSnapShot );
    return (DWORD)lpModuleEntry.modBaseAddr;
    }
    bModule = Module32Next( hSnapShot, &lpModuleEntry );
    }
    CloseHandle( hSnapShot );
    return NULL;
    }
