After getting great reviews on the previous version, I finally got time to do the rewrite that I promised everyone. This code allows you to easily create lists of your data with pagination, sorting, and filtering. The end result is a very nice layout of your data. You choose which fields come back (an the captions for each one in the header). Choose which fields are searched. Setup the default field that is sorted when visitor first views page. Now supports databases with list ordering. This time I have included a database so it should work as soon as you add the files to your website.

for computing a condensed representation of a message or a data file.

Converts a string ip address ("192.168.0.1") to a Long number (3232235521). One of the resons to do this would be to store IP addresses in databases. Numbers greatly reduce the size required to store this information.

Allows users to choose a color from a palette simular to Adobe's color palette.

Allows you to create 1x1 images of any color including transparent images. (Images can be streatched by defining height and width in image tag)

This version of the Color Picker supports just about any browser that uses javascript - Including Netscape 3. The downfall is that you "must" run it with a server that allows ASP. A script is included to create "dynamic" images of various colors. Thus - more bandwidth is used to allow visitors to choose colors. It is still a great asset to anyone who wishes to allow users to pick colors dynamically to affect the sites layout and design instantly.

Allows you to upload multiple files and fields without purchasing or registering COM objects. Great for shared hosts that frown upon 3rd Party com objects or charge an arm and a leg for them. This version uses Classes rather then the dictionary object that I have seem most other people use. Dictionary Objects seem to be flakey with more problems. I have added examples of how to upload a file to a database and the file system. A file is also included that retreives the file from the database.

This class is used to interpret phone numbers to and from a database in a specific format. The format is 25 characters long and is explaied withing the script.

This class demonstrates how you can request the HTML of a URL from another website using the XMLHTTP object to spider the web page. (Simular to the methods of the ASPHttp object). The data is parsed and made available through a class object. This code is great if you are thinking about creating a Search Engine - or you just want to verify that URLs exist that users may place in there profiles. Also handy for finding broken links. If your server has IE5, or XML objects from Microsoft installed on it, then you should be able to use this demonstration without any problems.

Measures the bandwidth in kbps (kilobits per second) that the client is viewing your website at. Works with modems, dsl, cable modems, network cards and any other means of connecting to the internet.

This script interacts with COM objects that communicate with the MetaBase for Internet Information Server. You will be able to define the custom error pages for your website.

This script colorizes your vbScript for display on web pages. All colors can be managed through a style sheet. It seems that those who knew about the results of this version (from browsing my website) always kept asking me for the code and my old version that I refered them to was out-dated and didn't come close enough to there expectations. So peeps - I give to you my most proud and recent version of the color coder.

RCA is used for most standard public key/private key encryption techniques. Due to its burden on resources, RCA is generally used to encrypt random session keys wich are then used to encode messages with RC4. RCA also brings digital certificates into the picture. This, and many other "public" algorithms using RC4 do not truly make the message secure. Encryption is performed in 8 bit blocks - or 1 byte. Typing "AAAAAA", you will see a pattern begin for form with the encrypted data. If someone were to look at the results from encrypting each letter of the alphabet, your data would be compromized. Also, the public/private keys are limited between a range of 1 and about 65000. This is primarily a starting point if you want to enable a more secure encryption scheme, or you just want to learn more about it.

Queries a WhoIs server for for domain information. Useful for people who want to sell domain names. This version uses the XMLHTTP component that is installed on most servers, so there is no additional need to install any extra COM objects.

Allows you to view the binary data of any file (GIF, JPG, ZIP, TXT, HTM, ASP) as if you were looking at a common hex viewer. Bytes are displayed as Hex characters and character data is displayed on the right. Starting positions of each row are displayed on the left.

This script helps start you off to learning how to automate some of your processes with SQL . For this example, I have chosen to send Email through SQL Server using vbScript. Messages are pulled from a table and deleted once they are sent. You need to create a table in the master database called "Email" and assign the fields "To", "From", "Subject" and "Body". The script will do the rest. If you "SA" account has a password, you will need to modify the script to relflect those changes.

Encrypts and Decrypts data using the RC4 algorithm and a Key/Password. Many thanks goes to many, many people on PSC and the internet for helping me through this. Sebastions code over at the Visual Basic section was a good start. This code runs quick in one function and is slightly commented. note - RSA patent expired in September 2000.

Applys Encryption/Decryption to strings. I think just about everyone who has seen my code knows how I love classes. This version is more "cleaned up" and thrown into a nice little class for an object oriented feeling. (If only ASP was object oriented, I would be a happy camper). It is also a little more optimized to run quicker if you change the Key/Password often.

Checks the HTTP Referer header to ensure people are not posting from other websites. You can include this file if you use templates on your website, or just include it on the pages that receive form data posts. Warning - someone who knows there stuff can get around this by modifying there HOST file. this isn't 100% fool proof, but it may deter most from posting data from other websites.

This code pulls out all the nasty tags that a user sholdn't use when posting content. It also pulls out any javascript events assigned to any tags. A must have if you allow people to post HTML on your site.
