    Re: Simple VB Write/Read Memory Class

    Just a note to this. The WriteProcessMemory function here is for single byte only. If you wish to change it for other datatype value here is how;

    Code:
    WriteProcessMemory(ProcessHandle, Address, Value (this is the buffer), Byte Size, 0&)
    Change Byte Size to either

    1 - single byte (Declare ByVal value As Byte)
    2 - 2 bytes (Declare ByVal value as Long)
    4 - 4 bytes (Declare ByVal value as Long)

    If you are searching for float value, Declare ByVal value as Single.

    Create Form then use this ReadProcessMemory function from Kernel32 (or take dwar's vb write/read memory class)
    then use ReadProcessMemory to read bytes, and then covert byte to data type u want..
