Help how to write protect memory?

[reavenz]

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?

thanks for helping

thanks for helping

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...

Do you even know what NOP means?

Do you even know what NOP means?

You should learn basics of cheat engine, c++, and assembly language.
Want learn? Go over the Wikipedia, and search through forums --> click here.
