I am developing a web application which will deal with online examination. The requirement is:
There can be n-number of sections in an exam and admin users should be able to create questions/answers and add to an exam. The questions should be displayed for a certain amount of time in the browser with meclock and it should move to next question automatically. User should not be allowed to open any other instance of the browser or login from another IP if the exam is in progress.
I am seeking community vote of how would someone design the application to meet all these criterias? What patterns should be used? What components to reduce the development time etc..My technology stack is C#, ASP.NET MVC or ASP.NET with SQL Server.

I am developing an applicaion for time sheet which uses gridview.
The columns are dynamically generated based upon the start date and end date.Its a biweekly pay period.
Apart from these 15 Day 1 to Day 15 columns there are 5 other columns for different codes which are added to gridview using data table. I have drop down list control for the 5 codes and text boxes for the remaining day 1 to day 15 columns.
Now when the user selects the values from the drop down list and enters the number of hours into the text box using a footer row with a inert link button it should add the values entered to the footer row to the data table data row and then rebind the data table to the data base. I am some how unable to get the values entered by user into the footer following is the code for insert_click event
Protected Sub lnkInsert_Click(ByVal sender As Object, ByVal e As EventArgs) Dim tb As TextBox = GridView1.FooterRow.FindControl("txtctrl6") End Sub Protected Sub lnkInsert_Click(ByVal sender As Object, ByVal e As EventArgs)

We've got a product built using ASP.NET web forms (3.5), and are investigating adding an API to allow other applications to access data and business logic within the application.
What is the best way to implement this? I'm inclined to go down the route of using Http Handlers to read posted XML and return XML, but I'm sure there must be a better way. Is it advisable to use something like WCF instead?As the product will be downloaded and installed by users on their own servers (instead of hosted), it seems like there's a lot of pressure to get it right the first time as making changes will be hard once users start downloading and using the product.
