good day sirs and madams,

I am new to dotnetnuke and I see how powerful this CMS is. I hope you could help me with my problem:

I need to configure the website (dotnetnuke) we have created such that it can connect/query/update an existing user database. for example, when I click on a link on my tab that says "quizzes" It will display quiz questions that are stored in an existing database.

I have tried to dig deeper into the aspx/aspx.vb core codes of dnn (like default.aspx) and I happen to find no trace of potential areas where I can insert vb/ asp.net code. Please try to help a newbie. It would be greatly appreciated.

additional:

where do you find the pages created? because as I have observed, they are all in default.aspx when you try to look at the URL. sorry, because I am so used to HTML, where as you link pages together and you navigate to that page when you click the link and you can see the code itself. In dotnetnuke, I don't see any. I was expecting that when I see the default.aspx code, I would see the links (like hrefs or some sort) to other pages/tabs whatever you call it, that I created.

Thanks for your time on helping a newbie. rest assured you'll be repaid by your kindness by a higher entity in this life!

thank you sir, I will watch it now. but im still wondering why it could be complicated. i have an idea, can i insert my existing database (or the tables of this database) into the database of dotnetnuke (where the content is located) and connect/query/update from there? if it is a good thing, any ideas how to do it? thanks for the support.

haha no sir, I'm pretty much hyped by the database problem because I badly need it.

Yes sir I'll be needing validation. this is the flow of my task:

a user logs in an existing portal, clicks the link to go to our portal, existing portal throws an encrypted string of the employee information, I should validate the input if it is a valid encrypted string (still dont know how to do that), validate its contents (employee info) and check it against a user database (the database I'm talking about. that I'm planning to put inside the dnn database because I can't find a way to access this database by hardcoding/inserting vb or asp.net scripts in the core code of dnn since as you've said, pages are dynamically loaded during runtime) and if the employee exists in the database, then I let him/her in, if not, I create a new record of the employee first, who visited the site probably his or her first time, and then let him or her in...

So you see sir, I am really dependent on this user database. I'll be getting quiz questions and quiz scores from here as well...
