Hello,

I understand how to determine a static address from a dynamic, but whats been wondering my mind is how to read a dynamic address for a pointer.

My question here is, what techniques or methods should I use to find a pointer to a dynamic address, thanks.

look at CE and look when you find a dynamic address and look at the code associated with it and see how CE suggests pointer values. usually a pointer is when there is some sort of dynamically allocated structure, maybe a class or maybe regular structure. a variable holds a pointer to the base/start of this structure. the offset is how far in a given member is

I see, I don't have Delphi installed on my PC to read CE.

How read off an address to know if its part of any class or any other regular structure?

Ideas, suggestions, functions, please and thanks.

Not the source, just do the tutorial and see if you can understand why it is suggesting the values it is.

What don't you understand about a dynamic pointer?

Get value of the address, add offsets to the value. If it's a multipointer just get value of initiate address, add offsets, get value of that offset+Address, repeat.

@&Vage Okay, so obtain the value from the dynamic address then add offsets to it? What offsets do I add to it to obtain the pointer?

Code:

DWORD Value = *(DWORD*) Address;

DWORD ApplicationBase = (DWORD) GetModuleHandle(0);

DWORD Offset = ApplicationBase - Address;

DWORD Pointer? = Value + Offset;


i'm really lost in what u just said.
