Online Examination System Project in ASP.NET July 11, 2008
Posted by tuse in : ASP.NET, Databases , 122 commentsThis is a project we made in ASP.NET. Its an examination system made in Visual Studio 2008 using a MySQL database. Please do take a look at it and suggest improvements. Also, if the project is vulnerable to any security threats, please do ping us back.
I hope you will like our attempt at coding this application.
Features-
User first needs to supply valid credentials to begin the test.
Randomly chooses 5 questions from a database of 10 questions.
The test is a timed test, admin can change the duration of the test before it begins in the code.
Test-taker can leave a question un-answered and come back to the question (if time permits) using the ‘Previous’ and ‘Next’ Buttons.
Code Details-
1. Login is authenticated against a MySQL database.
2. AJAX is used for the timer, allowing only the timer label to postback to the server each second.
3. Use of the Random class to generate 5 questions out of the 10 in the database.
4. Session Management using Cookies and Session Variables.
5. Use of javascript in the master-page to prevent the ‘Back’ navigation from a page (clearing the cache) [Would love your suggestions on an alternative to this]
6. Once the 5 questions are chosen randomly, they are held in a DataTable. This is then held in a Session Variable to hold the values during postbacks.
