C++ Authorization of vBulletin Members?

[motaaa]

Copy/Paste of a vBulletin support ticket I opened, they referred me to this site so here it is...

I'm not sure if you have any C++ coders, but if not could you point me in the right direction. I sell programs and I want to implement a code in my injector that asks for usernames and passwords, then encrypts them and matches them to my SQL. If they match, and are in the appropriate usergroup, then it will inject the DLL.

If they are not subscribed, then I want a message to come up asking them to please subscribe with a link to a subscription page. If there is a username/password mismatch then I want to tell them to please go register. As far as the DLL injection and error codes, I can handle that part. What I'm asking is if you guys have a way of comparing usernames/passwords and their appropriate usergroups from an exe to an SQL.
