Help how to write protect memory?
#1
u have code write protect memory.
like this
Code:
Public Declare Function VirtualProtectEx Lib "kernel32" (ByVal hProcess As IntPtr, ByVal lpAddress As Integer, ByVal dwSize As Integer, ByVal flNewProtect As Integer, <Out>ByRef lpflOldProtect As Integer) As Boolean

but how to use it?

or some body can give me sample to NOP function in vb.net?

Code:
Dim oldProtect As Integer = 0
Dim PAGE_EXECUTE_READWRITE As Integer = &H40
'TargetAddress is the address you want to write to such as &H12345
'BytesToWrite is how many bytes you are intended to write, for example if you are NOPing 10 bytes, you specify 10.
'If you are writing an Integer, you specify 4 since an Integer is 4 bytes long.
VirtualProtectEx(processHandle, TargetAddress, BytesToWrite, PAGE_EXECUTE_READWRITE, oldProtect) 'Unprotect the memory

'----- Peform whatever you need to do such as writing memory -------

'Restore the memory to protected again to prevent problems
VirtualProtectEx(processHandle, TargetAddress, BytesToWrite, oldProtect, 0)

Oh and by the way, NOP = &H90. Don't understand? Learn more about memory hacking first...

You should learn basics of cheat engine, c++, and assembly language.
