 Posted: Thu Sep 01, 2011 3:43 pm Post subject: [C++] How to read pointers with ReadProcess |
 |
|
Heya, I've been trying to get a view of different variables of a game in my program, and I've been using this function, which works fine with non-pointer addresses, for example if I input 3E2CD4 as the address I get the hit points and so on. But I can't get a 2nd-level pointer to work.
| Code: | int addressHandler::readAddress( unsigned long address, string handleName )
{
int value = -1;
HANDLE phandle = getHandle( handleName );
int addr = base + address;
if(!phandle)
{
MessageBoxA(NULL, "Could not get handle!", "title", NULL);
return -1;
}
ReadProcessMemory(phandle,LPCVOID(addr),&value,4,0);
cout << value;
return value;
} |
I've tried using the "method" posted here (couldn't post urls for some reason, but viewtopic.php?p=4386205#4386205)
I modified the function to look like this (just for testing):
| Code: | int addressHandler::readAddress( unsigned long address, string handleName )
{
int value = -1;
HANDLE phandle = getHandle( handleName );
int addr = base + address;
if(!phandle)
{
MessageBoxA(NULL, "Could not get handle!", "title", NULL);
return -1;
}
DWORD pid;
HWND hwnd = FindWindow(NULL,handleName.c_str());
GetWindowThreadProcessId(hwnd,&pid);
DWORD *thefirst = (DWORD*)(*(DWORD*)GetModuleBase( (LPSTR)handleName.c_str(), pid ) + 0x46F694 + 0x1c);
DWORD *thesecond = (DWORD*)(*(DWORD*)thefirst + 0x20);
ReadProcessMemory(phandle,LPCVOID(thesecond),&value,4,0);
cout << value;
return value;
} |
But it just returns -1.
I've searched the forums but haven't really found any other thread than the one I linked. If this has already been asked and resolved before I humbly ask for a link to that topic, and apologize for this post.
Thanks!

You may need to use ReadProcessMemory multiple times (or loop) to get the multi level pointer.
This is how I find a multi level pointer.
I first write these codes in C#, then rewrite them in c++, tested with the game "The Baconing", it should work fine.
| Code: | int FindPointerAddr(HANDLE pHandle,int baseaddr, int pLevel, int offset0 = 0,int offset1 = 0,int offset2 = 0,int offset3 = 0, int offset4 = 0)
{
int Address = baseaddr;
int offset = 0;
for (int i = 0; i < pLevel; i++)
{
if (i == 0)
{
offset = offset0;
}
else if (i == 1)
{
offset = offset1;
}
else if (i == 2)
{
offset = offset2;
}
else if (i == 3)
{
offset = offset3;
}
else if (i == 4)
{
offset = offset4;
}
ReadProcessMemory(pHandle, (LPCVOID)Address, &Address , 4, NULL);
Address += offset;
}
return Address;
} |
EXAMPLE: (Offsets are optional)
2nd level pointer example:
| Code: | int offset0 = 0x678;
int offset1 = 0x14;
int myaddr = FindPointerAddr(ProcessHandle, 0x00270740, 2, offset0, offset1);
MessageBox::Show("The Address is : " + String::Format("{0:X}",myaddr)); |
5th level pointer example:
| Code: |
int offset0 = 0x678;
int offset1 = 0x14;
int offset2 = 0x758;
int offset3 = 0x678;
int offset4 = 0x5B4;
int myaddr = FindPointerAddr(ProcessHandle, 0x00270740, 5, offset0, offset1, offset2, offset3, offset4);
MessageBox::Show("The Address is : " + String::Format("{0:X}",myaddr));
