Well, i creat a site and in the site I creat a sample login, when the person enter in the site after put the nick and the password, I want that appears in the part of the user, my nickname. based in the database...

How I do it?

can't understand you so well. you are saying you had made a log in page right? so do you need to make a code to check the log in info or what? also from where does it get the user information? access database?

You have to access your database and Table which have your Nick saved with the help of ASP script.
