Hi, my name is Nicusor,
I have found this code on the net, first I changed the HKEY_LOCAL_MACHINE to HKEY_CURRENT_USER just to find out that you can't ChangeEvent is not supported for HKEY_CURRENT_USER.
I am trying to add two arguments to this application (consoleapplication16.exe)
so it will sound like : consoleapplication16.exe S-1-5-21-4054269417-2950973813-1693298518-1000 snoop_creep
where S-1-5-21-4054269417-2950973813-1693298518-1000 is the SID and snoop_creep is the yahoo id
I am a beginer in C# I'm still learning.
It will be nice if someone could help me.
I am using Microsoft Visual Studio 2010.
Thank you in advance and sorry for my English.
This is the code:
