Quiz

1:

What must ASP.NET do before it sends anything to the browser?

A1:

Convert the output to HTML so the browser can understand it.

2:

What does CLR stand for?

A1:

Common Language Runtime.

3:

What is metadata?

A1:

Information produced by an application to describe its properties. The Common Language Runtime uses metadata to load and run applications.

4:

What are three programmatic improvements of ASP.NET over ASP?

A1:

Ease of deployment, improved session state, and the use of code declaration blocks.

5:

How does ASP.NET work with the client and server machines?

A1:

ASP.NET uses client-side code to send messages back to the server. Thus, the server can be aware of what's happening on the client.

6:

Why can't you simply double-click on an ASP.NET file to run it?

A1:

An ASP.NET page must be processed by a Web server. If you double-click on it, you're trying to open the file without using that process.

7:

What is a virtual directory?

A1:

A folder on your computer that can be accessed from a browser as though it were in your root directory (typically, c:\inetpub\wwwroot).

8:

If you created a file called hello.aspx and placed it in the c:\inetpub\wwwroot\tyaspnet21days\MyApplication directory, how could you access it from the Web browser?

A1:

At the following URL:

http://localhost/tyaspnet21days/MyApplication/hello.aspx

9:

What's the difference between code declaration blocks and render blocks?

A1:

Code render blocks are inline code, denoted by <% and %> tags, and aren't compiled. Code declaration blocks define a page's methods and members, are denoted by script tags, and are compiled.

Exercises

Q1:

What will be the output of the following ASP.NET page? Where would you save this file so users could access it?

 1:    <%@ Page Language="VB" %> 2: 3:    <script runat="server"> 4:       sub Page_Load(Sender as Object, e as EventArgs) 5:          lblMessage.Text = "This is my first exercise!" 6:       end sub 7:    </script> 8: 9:    <html><body> 10:       <asp:Label  runat="server"/> 11:     </body></html> 
A1:

This page would display "This is my first exercise!" You could save this file in the c:\inetpub\wwwroot\tyaspnet21days\day1 folder as exercise1.aspx and view it through the browser with http://localhost/tyaspnet21days/day1/exercise1.aspx.
