calling objects in asp.net [beginner's question]

[hyper88]

Hi All, I have coded a class with the namespace quiz, it contains some methods like adding questions into database and validations.

Now i want to use it with asp.net, what do i need do in order to be able to call the class in code behind or in the asp.net page itself.

Another question is how do i pass an object (maybe a car object with mileage values, model etc) from 1 aspx page to another or keeping it in the session so i can retreive it whenever i need it.

Sorry, but i have tried to google and search the forum but couldnt get any answers. Maybe my phrasing for the search is bad. Thanks in advance.

cheers

Question 1)
You should just be able to add a reference to your ASP.Net project and use the object from there.

Question 2)
If you want to add objects to your session, I'm going to reffer you to the same question I had awhile back:

The example uses a dataset, but it would be easy to do the same thing with a structure.

Bah Bah Bah
ViewState is for current page only. You would have to use session. Ignore that link! I suck...

To sevenhalo, Thanks for the prompt reply. It helped.
You don't suck. We are all learning.

You have to instantiate it:

Dim oQuiz as new Quiz

And then you use the newly created oQuiz object to access methods and properties.

EDIT: If that class is a stand alone DLL library, you have to reference it to the proyect, and THEN instantiate it.

Another question is how do i pass an object (maybe a car object with mileage values, model etc) from 1 aspx page to another or keeping it in the session so i can retreive it whenever i need it.

If it's a complex object, like a array of strings, just use sessions.

You can do:

Dim myObject(5) as String
Session("myObject") = myObject

And to read it from anywhere:

Dim myObject() as string = Session("myObject")

To check if the Session("myObject") actually has a value, you can do this:

If Session("myObject") Is Nothing = False Then
   'do something
End If
