How long will the best software-only protections last?

Hi,
Thanks Dyn!o and D-Jester for all you said.
But what I meant was not Code-Lock.
I was talking about a custom protection made by a russian reverser used in program which is written in VC++ using MFC privileges.
And this MFC part has mede the reversing very hard.

Anyway,if any body is interseted I have the software on my FTP and I can share it.
Just send a PM if you need the link and more details about this program.

Best Regards,
Android.
