HelpGetting started with C++ DLL hacking - Basic Memory Editing
C++ DLL Problem - Program Crashing
So basically i've made a dll ready to inject into Garry's Mod (hl2.exe) but whenever i inject it into hl2.exe, hl2.exe crashes!
Could someone please tell me why my dll is making the program crash?
Here's my script for the dll:
Thanks in advance!

Here's my script for the dll:
Code:
#include <windows.h>
DWORD Base = (DWORD)GetModuleHandle((LPCTSTR)"client.dll") + (DWORD)0x5B5340;
DWORD* Address = (DWORD*)Base;
void mainthread() {
while(1) {
*Address = 2;
Sleep(250);
}
}
BOOL APIENTRY DllMain(HINSTANCE hDll, DWORD callReason, LPVOID lpReserved) {
if(callReason == DLL_PROCESS_ATTACH) {
CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)&mainthread, 0, 0, 0);
MessageBoxA(NULL,"Hack Injected Successfully!", "DLL Injection" ,NULL);
}
return 1;
}
I'm not 100% percent sure, but I think Garry's Mod shuts down if it detects anything being edited from an exterior?
I'm not sure though.

And still i get the same crash when i try a different method...
Code:
#include <windows.h>
#include <stdio.h>
#define ADR_Wallhack GetModuleHandle("client.dll") + 0x005B5340
void mainthread() {
while(1) {
DWORD OldProt;
int WallhackOn = 2;
int WallhackOff = 1;
VirtualProtect((void*)ADR_Wallhack, sizeof(WallhackOn), PAGE_READWRITE, &OldProt);
memcpy((void*)ADR_Wallhack, &WallhackOn, sizeof(WallhackOn));
VirtualProtect((void*)ADR_Wallhack, sizeof(WallhackOn), OldProt, 0;
Sleep(250);
}
}
BOOL APIENTRY DllMain(HINSTANCE hDll, DWORD callReason, LPVOID lpReserved) {
if(callReason == DLL_PROCESS_ATTACH) {
CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)&mainthread, 0, 0, 0);
MessageBoxA(NULL,"Hack Written Successful", "DLL Injection" ,NULL);
}
return 1;
}
