Cheat Engine

[kitesan]

on what does depend the size of the address (of the allocated region) (not the size of the region) when you alloc memory by calling VirtualAllocEx?
When you use CheatEngine's code injection it comes out an address like:

13FFE0000

and when you go in Tools, Allocate Memory, it comes out an address like:

01FB0000

why? different parameters or something else? I'm trying to write a program
which handles 64bit processes and allocates memory

it's completely random what address you get.
You can give a hint where to allocate it though

Thanks infinitely , can you give me a basic example?
to have an overall concept of hint

by knowing this

LPVOID WINAPI VirtualAllocEx(
_In_ HANDLE hProcess,
_In_opt_ LPVOID lpAddress,
_In_ SIZE_T dwSize,
_In_ DWORD flAllocationType,
_In_ DWORD flProtect
);

the hint is given to the second parameter?

[Dark Byte]

yes, also make sure lpAddress is dividable by 64KB , and preferably points to a block currently not allocated.

thanks again
