Code protection

[Johnny Jörgensen]

I've got some code contained in a component in a dll that I want to protect
against reverse engineering - but I've never done anything like that before,
so I'm wondering a few things:

1) What brand of obfuscation software provides best protection at a
reasonable cost? Have you got any recommendations?

2) If I obfuscate the dll containing the component, will it still be
possible to add the component to the VS toolbox and use it in projects that
are not obfuscated or perhaps obfuscated using a different tool?

3) Does addind the "DebuggerHidden" attribute to the critical code sections
protect anything at all?`

Cheers,
Johnny J.

Microsoft has some tools for this. Check out this link:

If you go to the downloads section, there is a code protector you can
download. Perhaps this will work for you.
