Ok so I'm trying to convert an aob template to c++ code.

This is the script. ->
[ENABLE]

aobscan(INJECT,8B 84 18 0C 02 00 00) // should be unique
alloc(newmem,$1000)

label(code)
label(return)

newmem:

code:
// mov eax,[eax+ebx+0000020C]
jmp return

INJECT:
jmp newmem
nop
nop
return:
registersymbol(INJECT)

[DISABLE]

INJECT:
db 8B 84 18 0C 02 00 00

unregistersymbol(INJECT)
dealloc(newmem)


Now , this is my attempt at c++ to convert it.
#include <iostream>
#include <Windows.h>

using namespace std;

int main()
{

HWND hwnd = FindWindowA(NULL, "GraalOnline Classic - Mozilla Firefox");
if (hwnd == NULL)
{
cout << "Could not find window." << endl;
Sleep(5000);
exit(-1);
}
else
{
DWORD procID;
GetWindowThreadProcessId(hwnd, &procID);
HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, procID);

if (procID == NULL)
{
cout << "Process was not found." << endl;
Sleep(5000);
exit(-1);
}
else {
WriteProcessMemory(handle, address, 0x90, 1, NULL);
}


}

Now the problem is the address. The address changes every single time and I have tried to find the base address using pointer scans but for some reason that has not worked out for me. Is it mandatory to give the address in order to NOP the bytes? In my case , it is 8B 84 18 0C 02 00 00.

All right , so I revised my code and now it looks like this ->


#include <iostream>
#include <Windows.h>
#include <WinDef.h>

using namespace std;



int main()
{


HWND hwnd = FindWindowA(NULL, "window");
if (hwnd == NULL)
{
cout << "Could not find window." << endl;
Sleep(5000);
exit(-1);
}

else
{
DWORD procID;
GetWindowThreadProcessId(hwnd, &procID);
HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, procID);

if (procID == NULL)
{
cout << "Cannot find window" << endl;
Sleep(5000);
exit(-1);
}
else
{


if (GetAsyncKeyState(VK_SPACE))
{


BYTE nop[] = { 0x90 };

WriteProcessMemory(handle, (LPVOID*)(void *)0x0909A41F, &nop, 1, NULL);
}
if (GetAsyncKeyState(VK_INSERT))
{
cout << "aa" << endl;
}

}




}
return 0;

}

Problem is , the program exits like this right after I debug it-> .exe has exited with code 0 (0x0)
