Unit 8: ASP Web Forms

 When it’s time for you to look for a job, how will you begin your search? You know Notes
you can’t just wander up and down the street, knocking on doors randomly. That
would be time-consuming, exhausting, and counterproductive.
 Even pop-up cans of soda include instructions: “1. Lift up. 2. Pull back. 3. Push
down.” When such simple items need instructions, you can imagine how necessary
instructions are for complex products and procedures.
 Professionals in electronics, engineering, medical fields, the computer industry,
and other technologies often rank the ability to communicate as highly as they do
technical skills.

 The best delivery by the most polished professional will lack credibility if the
speaker has nothing to say.
We have ample examples of the last thing when we watch seasoned politicians answering
queries or bureaucrat spokesmen warding off the press.
For the ASPirants
DOUGLAS J. Reilly’s Designing Microsoft ASP.NET applicationsgives expert guidance —
as it is from Microsoft Press — on how to use the powerful new functionality of ASP.NET
(the next generation of Active Server Pages) to build dynamic, scalable Web-based
applications. A few picks:
Compiled languages allow the developer to verify that code is at least syntactically correct.
ASP doesn’t provide any such facility, so simple syntax errors might not be caught until
the first time the code is executed.
When developing real-world systems today, you’ll encounter two significant problems:
one is the problem of making software work on multiple platforms, and the other is the
problem of enabling the various pieces of an application written in different languages to
communicate.
Using ASP.NET gives you access to the newest and greatest in many areas of server
programming, but if you want to use ASP.NET to display a message box, you’re out of
luck. However, there is a way to present message boxes and other similar close user
interactions. The answer is client-side scripting.

The ability to create data-driven, dynamic content is at the heart of what made ASP such a
hit. ASP.NET continues the tradition of easy data access. It adds integrated, pervasive
support for XML.
Read it if you’re not already gasping for breath.
Net concepts
DOUGLAS E. Comer’s Computer networks and Internets is an introductory text that uses
analogies and examples to define concepts instead of sophisticated mathematical proofs.
A few picks:

 In practice, no electronic device can produce an exact voltage or change from one
voltage to another instantly. Furthermore, no wire conducts electricity perfectly —
as electric current travels down the wire, the signal loses energy.
 In most countries, laws prevent an organisation from connecting sites with optical
fibre unless the organisation owns all the property between the sites and the fibre
does not need to cross a public street.
