Functions and Subroutines in ASP
If you read our Tutorial on Include Files (SSI) then you learned how to encapsulate ASP code within include files and the benefits it brings us.
As developers, we should endeavour to make our lives easier wherever possible... no one wants to re-invent the wheel after all.
Functions and Subroutines exist to not only save us time, but to bring power to our ASP.
They are just another way of encapsulating code, but have a lot more functionality than just 'saving some code for later'.
First, let's look at Functions... Imagine a balloon salesman in the street. We've all seen them they require one piece of information when you buy a balloon, the colour.
Let say we asked for a red balloon... The balloon salesman armed with this 'information' then does a pretty basic action... he hands you the balloon. The balloon you received is a direct result of the information you gave the balloon seller.
Functions are just the same... they return to you a value based on the information you provided. Lets look at an example Function: -
<%
Function getBalloon(strColour)
Dim Tempstr
strColour = lcase(strColour) 'This converts the value lowercase.
Select Case strColour
Case "red" Tempstr = "Here is your red balloon"
Case "yellow" Tempstr = "Here is your yellow balloon"
Case "green" Tempstr = "Here is your green balloon"
Case "blue" Tempstr = "Here is your blue balloon"
Case Else Tempstr = "Sorry, we have sold out of that Colour"
End Select
getBalloon = Tempstr
End Function%>

Server Side Includes (SSI) with ASP
People often have identical sections of code spread throughout many ASP pages, typically code at the top of the page (usually referred to as the header) and the lower part of the page (the footer). Similarly, you may have code that performs a certain set of instructions that you are repeating across multiple pages. Consider an example:-
The Topic Of Your Website
The first thing you will have to deal building your website has nothing to do with the web design itself, it's me related to content writing but it must be defined and will effect the rest of your actions. So first of all you need to decide what the topic of your future website is. Topic is very closely connected to another web design issue: keywords. The keywords you select will depend upon the topic you have chosen. When thinking about website topic ask yourself a few questions: What is the goal of the site you are making? What are you trying to achieve with your site. Specify a goal, preferably in one short sentence.
Ecommerce for Beginners
Like most average persons, I wanted some extra money to supplement my regular income. I had considered a part time second job at times, but hated that option because it would take me away from the family, make me more tired and probably just pay minimum wage. I also wanted to be able to work from home.
What is The Google Toolbar'
No matter what browser you may want to use, you should consider using Google's toolbar. Google.com, the innovative, stripped-down, add-free search engine that has taken the web by storm has provided an innovative interface through most web browsers; mainly Internet Explorer. This toolbar has many great features for searching around the Internet as well as blocking those annoying Pop-up ads that scream 'BUY ME!? every twenty seconds.
What is Blogger.com'
In the late 1990's three San Francisco based web developers came up with the idea of being able to share information about anything on the web. The terminology they used was called blog. It's use was considered a mix of web page / personal journal. It's original usages were vast and wide, but more and more people came to use them as a personal tool that is available anywhere the Internet is. The three friends would eventually create Blogger.com one of the largest blogger sites on the Internet today. Blogger, which stands for Web Logger, has increased in popularity over the past three years. There has been so much interest in what capabilities it holds Google.com purchased them. Eventually, Google assimilated their technologies and imported them into the popular plug-in, The Google Toolbar.
How To Write More Powerful Online Text
Although there are significant differences among the various types of online communication, there all have one critical thing in common - they're read off a screen. There are substantial benefits, too, in that while your message is on someone's screen usually it has their undivided attention. You are genuinely "one-to-one" with them and that's something you must respect - you are literally "in their face" and encroaching on very personal territory. The bad news about online communications is that your message can be "disappeared" faster from a screen than with any other medium.
What Hosting Companies Dont Tell You, Could Hurt You'

Are Web Graphics Stealing Your Money'
They might not be wearing a mask and carrying a gun, but if you've got images on your web pages then they could be costing you a lot more money than you think every time a visitor looks at one. That's because image files are typically the biggest bandwidth user on any web page. Whenever a visitor's browser is displaying an image on your site, it's actually downloading that image to the local user's hard drive. When anything gets downloaded, it uses bandwidth and bandwidth costs money. The moral of that story is: The bigger the image the more bandwidth it consumes.
