Hello, I have this application that would let a user register (I used an ASP.NET control for that one), and then log in (I do not use ASP.NET control for the login, I am making it myself). When an user register, I am sending their data to an Oracle database, so now when someone tries to log in, I want to be able to check whether they are registered or not, i.e. whether the database contains that particular username and password or not. But I do not want to have the data in the database shown in any control, so I have no idea how would I check that. If I'm using a Listbox e.g., I would retrieve the data into the listbox, and then check whether the entered text in the UsernameTextbox is equal to some data in the listbox or not. Without that kind of controls, I do not know how to check for the entered data into the database. Is there any way of checking via the SqlDataSource or something ? Thank you, greetings.
