After the installation of PWS, you will find a PWS icon on your desktop and probably a PWS small icon in the tray on the right lower corner of your desktop too. Double click any of them to bring up the PWS control window. If the PWS is already running then you will see an option 'Stop PWS'. But if PWS has been stopped and is not running then you will see the option to 'Start PWS'. Since we want to check that PWS has installed successfully and everything is running optimally, you should start the PWS if it is not already running. If it has started on its own then don't do anything.
Ok, now we want to check if PWS is running correctly and Active Server Pages are running or can be run. Open your Internet browser e.g. Microsoft Internet Explorer. In the URL box enter http://127.0.0.1 and press enter. If all is well then you will see a default page generated by PWS. When you install PWS it also sort of builds a default web site on your system, and that is what we tested here. If you can see some page then PWS is running correctly and we are done. But if PWS is running and you cannot see any page by entering the above URL then you might need to restart your computer and then start PWS again and then open your browser and enter the URL as given above. Hopefully everything will be alright now. Installation of PWS is very eay and most of times everything is done without any problems.
Note that to see .asp pages you cannot see them just be opening them in browser without the 'http' protocol. You have to append http://127.0.0.1/ before the page name and address to see it running on your own local computer. More on that later. For now you have successfully installed PWS and now we are ready to create some simple Active Server Pages.
Your first ASP page
Open you favorite text editor ( notepad ). ASP pages may be developed using expensive editors like Microsoft Visual Interdev but that is out of scope as far as this tutorial is concerned. So notepad is all we need.
Here we will be using VBScript for writing .asp pages. Note that you can also use JScript or PerlScript to write Active Server Pages. Write down the following in your notepad :
<html> <head> </head> <body> </body> </html>
Well this is simple HTML and has no ASP code. Don't worry we'll be adding our ASP code on it. Now add the following line at the top of your <html> tag ( see above ) in your notepad.
<% @ Language=VBScript %>
Yes thats our first ASP code. This line tells the ASP code parser that we will be using VBScript to write code in this .asp page. If you would later want to use JScript or PerlScript then you might add JScript or PerlScript as the case may be in place of VBScript. But for now we will stick to VBScript. Ok, done that ? now add the following code between the <body> and </body> tags.
<% Response.Write "Hello World!" %>
Now save the page as 'helloworld.asp' in your c:/inetpub/wwwroot directory or where your wwwroot directory exists. Open your browser and type http://127.0.0.1/helloworld.asp in the URL box and hit enter. You will see an empty white page with Hello World written on top left. Well congratulations you just built your own first Active Server Page. If you see the code ( view -> source ( in your browser ) ) you will come to know that only the output Hello World! is there with the HTML tags and no <%, %>, Response.Write or Language ASP code is there. That is because ASP is a server side scripting language and all the code which we wrote is executed on the server and only the output generated is shown to the browser.
