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!

This article is number three in a series of articles I wrote about uploading and displaying binary data with ASP. The first article was about Uploading binary data to the database, second was on Displaying binary data from the database and the third one ( this one ) is going to be on 'Uploading files to the server hard disk

The previous article was about uploading files using VBA and IE. But what to do if you have only VBS (in WSH, IE or ASP)? VBS does not have functions which can work with binary data so you cannot read contents of a file from disk.
But you can use several objects which lets you work with binary data (one of them is also on this site, ScriptUtilities). ADODB, which is included in a free microsoft data access sofware (MDAC), enables the work with binary data also.
You can use ScriptUtils.ASPForm to accept uploaded files in ASP. ScriptUtils.ASPForm contains hi-performance, low resources consumption algorithm which can accept up to 2GB of data.

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.

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.
