Auto-Updating hack through Patterns/Sig Scans?

Hello,

someone long ago told me it's possible to make your DLL auto update on every CA update.
How I asked?
He sed via Signature scans.

Theory 1:
His DLL would scan for the correct addresses, logs it to a text file, the DLL reads the addresses and so it's updated.

Theory 2:
His DLL would scan for the correct addresses, adds them to the registery, reads them, and the hack is updated.

Those are the only 2 theories I could think of at the moment.
Can anybody help or give some kind of source code?

Thanks!

1. I posted 1 thread under this, how to make slefupdating signatures. Worked for me since 5 patches now, nothing wrong.
2. If you would know what you are doing, you would know you can save your logged address in a DWORD. You dont need to save it in a fucking textfile 0_o
