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.

Xao Xiong originally posted his version of DecodeURL and asked for a reply for a better way. I replied, but it didn't turn out too well, so i'm posting it here for him to see. The approach i took is that when you look at an encoded URL string, 2 hex characters follow a percent sign. XAO listed a few to translate into actual characters, but he didn't account for all 256 of them. Check it out!

This code lets you decode your scripts. It comes in handy if you deleted the original file or wrote over it with the encoded version. Microsoft included a program to encode, but choose not to let us decode with a scrdec program. More details can be found on my site about this script including a live demonstration. Please leave comments here if you wish to inquire about it.

Embed binary files within your programs to be written out to the file system once the program runs. This demonstration creates a Word document.

The Image 2 Ascii converter allows you to load a photograph, and then generate an ascii image that looks simular to it. You can use this ascii version to post a picture of your self on news groups, message boards, email signatures, and more. No longer is text-only formatting a constraint for displaying photographs!

I was searching on the 'net for a whois COM object and everyone is charging $20 - $250 for a very simple object. I was a little low on cash and had the day off. This COM object includes ASP code and a list of over 250 whois databases on the net.

Working on a clip-board spy to understand how data is saved within the clipboard. Still cleaning up a few things - but it works for the most part.

Determines if a file is old. I use this when I loop through the files in a "temp" directory to determine if I should delete old files on a website. Take note - the function looks at the last modified date rather then the date created.

Quickly find out the type of variables returned from your adodb recordset. TypeName() function doesn't do the trick. Databases offer additional data types. This script helps solve type problems without having to lookup the name of the numbers returned.

Display accurate time to your visitors! This script requests the UTC time from a server that is syncronized with an atomic clock. It then adjusts the time according to timezone and if daylight savings time is in effect.

Peer into the brains of a professional programmer to learn how to become a better coder and more easily maintain your code for management and easily allow others to understand.

Simulate the tab control found at the bottom of popular programs such as visual Interdev and Front Page.

Quick way to learn how to speak gibberish. It is sometimes known as "girl-speak".

Forces users to have choice of downloading a binary file. This was becomming a problem with Word documents - as they would either open within the browser or open externally. You may need to change the FileName variable.

I was working on a scriptlet to allow users to choose a color. A color wheel is displayed with an assortment of colors - most of witch are web-safe. Clicking on a color causes it to be outlined and raise an event that a color was chosen. This object mimics one of the color-picker forms found in Microsoft Office 2000. This scriplet does not yet raise events or expose properties. The basics, however are available for you to be amazed.

Allows you to read the width and height for GIF, JPEG (JPG/JFIF), Bitmap(BMP), and PNG files. You can upload a file or load a binary file from the server in the demonstration. This is great when you allow users to Upload files and need to ensure that they fit within a specific set of boundries (ie - uploading banners). Update - Now supports AVI, MOV, MPG/MPEG, and SWF with support from my brother Lucas Moten. JPEG files have also been fixed to read correctly.

Grab the opposite 6 character HEX color. This sums up David Weirs Color invert script with just one line of code. See his original code at http://www.pscode.com/vb/scripts/showcode.asp?txtCodeId=7176&lngWId=4 Be careful when comming close to middle gray scale (808080). opposites are same.
