Registration System +SQL Server
Hello,
I have done this project once before using an external DLL and NSIS, but I since lost my src, and don't want to rewrite the whole thing if I don't have to....Here is my question..
What is the easiest way to make a registration system in NSIS..where the user is prompted for a registration code....once entered...the program looks at a SQL Server 2005 database to see if the registration code is valid....if it is...it lets them continue...if it isn't ...it tells them.. "Invalid Code", if the code they entered is already used...then it would give them the message "Code used too many times" or something similar...
Besides using an exteral DLL for this...what other solutions are there?
Thanks,
Kyle
