Essay Questions
92.
What are the advantages of using web applications vs. window applications?
One set of advantages revolves around the centralized nature of the server side of a client/server
architecture. Code that is written for each unique application resides on a web server, not on the
thousands of end-user’s machines.
When the software is developed or changed the code is installed on the centralized server, thus
saving the expense of installing the new or updated on thousands of machines. It is also easier to
deploy any supporting documentation through this central location of a web server.
The other advantages stem from the universal nature of Internet access and web browsers.
Virtually every operating system supports the use of a web browser to access the Internet, which
makes developing web applications platform independent. Web browsers are easy to use and
available on virtually every computer.

Your ASP.NET web form, named MyWebProject, is located on a web server. (a) Describe the
two main files of the web form. (b) A user requests to see your web page. What does the web
server do to create your page? (c) The user pressed a button to request that two numbers are
added together. Describe the sequence of events that leads to the user seeing the new web page
with the correct answer.
(a) The first part is the graphical user interface (GUI) form which holds the controls the user
sees and interacts with. The file is called MyWebProject.aspx. The second part is the code
behind the interface, which responds to the events generated by the controls. This file is called
MyWebProject.aspx.vb.
(b) When a page is requested the web server creates a new class based on these two files. This
class contains a static HTML page, the server side (ASP.NET) controls, and the VB code. This
class will then generate the HTML page and send it to the user’s browser.
(c) When the user clicks on a button control, an event is generated and the browser sends a
postback request to the server. The web form on the server uses the code in the
MyWebProject.aspx file to process the request. A new web page is generated and sent back to the
browser.
