Firstly, it demonstrates the use of the FileSystemObject, and secondly it shows how powerful regular expressions can be. I learnt all I know about regular expressions from Microsoft's online documentation and a lot of experimentation!

Following active server pages code delete a file. Example uses FileSystem object to delete the file. Do not forget to double check permissions for this operation.

Why should you let visitors upload pictures onto your Web site?

Well lets take a couple of examples. People renting their holiday homes might like to display a picture of the property on a Web site. News sites might like to allow people to send them pictures of events in their area. Ideally we would like the visitor to be able to upload these pictures themselves using their standard Web browser.

Unfortunately images come in thousands of different formats, shapes, colors and sizes; almost none of which will mesh in with your beautifully designed site. This article is about how we can best solve this problem. To do this we will have to search down into the depths of HTML and ASP.

Digging down, the first gem we find is HTML upload. This is based around a standard, but vastly underused, HTML form element. When you put it into a form on a Web page it allows you to choose a file. When you submit the form, the file is sent to the Web server. What could be more perfect?

The second gem we find is the vast range of Active Server Page Extensions that exist on the market. These ActiveX controls add extra functions to the standard Active Server Page repertoire and can be accessed from simple scripting languages such as VBScript. The ASP Extension we will use here is the ImageGoo (http://www.websupergoo.com) Web graphics toolkit as it incorporates everything we need in one package.

This article illustrates some great uses of the File System Object. It shows how to choose a drive to search, and then builds a listbox of all the folders on that drive. Choose a folder and it builds a listbox of all the files in that folder. Choose a File and it will display it in the browser or prompt you to save the file to your hard drive.

This example code demonstrates how to link and display text files within a single document in ASP. Using the title of the text files as hyperlinks, when clicked the file name, the full contents of the document will be displayed. Very useful for making copybooks and file layouts available online.
