Usually we see static Captcha, now we will make an animated Captcha. Now this is cool. What does the captcha look like? It just like the ordinary Captcha, the difference is the letters are moving and animated. You can set your Captcha setting quickly such as random letter color, random background color, font size, etc. But do not wory, even this Captcha is animated, it won't blink too much so that visitor still can read the text easily. My code also support build-in method to check user's input. Captcha is easy, and interesting with animated Captcha. For more information, please read the readme file. I include the example file in my ZIP.

Finally, an CAPCTHA implementation., that too in ASP. This ASP CAPCHA is capable to generating Images on the Fly. Captcha's are generated based on ur requuirement.

[*] ActiveX Wrapper for GD by Trevor Herselman in his code http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=9202&lngWId=4 CAPTCHA is an acronym for "Completely Automated Public Turing Test to Tell Computers and Humans Apart". As the name suggests, it's a test to distinguish the degree of being human. As defined on the CAPTCHA home page at the Carnegie Melon University School of Computer Science's Web site: CAPTCHA is a program that can generate and grade tests that: • Most humans can pass. • Current computer programs can't pass.

UPDATED: Now supports database backup (optional)! Backup your whole website in zip format, get it via mail! Who doesn't know how important it is to backup your site/blog often? Again, if you use dynamic sites such as Joomla or a forum (e.g. IPB), there is always a risk to be hacked, no matter how security concern you are! In my experience, it is not always easy to regularly maintain backups, especially, if you don't have a good internet connection. What if your site prepare backups for you and send it automatically to your inbox (Gmail, perhaps)? This script do the same: icon11.gif Backup your whole website/blog by compressing it in zip format icon11.gif Split the zip files to smaller size so that you can easily get them via mail. (Gmail doesn't allow attachments more than 10 MB, this splitting solves this problem) icon11.gif Send backup files to you via mail! Without relying to basic PHP Mail, this script send mail via SMTP (authentication supported), which is much more powerful. In our test run, it could send 250 MB backup file in small 9 MB pieces each to a GMail account!

Simple code that allows users to login & register(Developped by a 14 years old student). Please vote for my code if you like it!!!

the code checks password enter by the user but it is different type,any can not see ur password which is saved to text file named pass.txt,because the program converts the password set by user in different format and when checked by program it reads from it and convert it to original form and compare it with password enter by user,if matched then allow to enter next otherwise exit to system.

This is the ASP version of a CGI technique used to scare off spammers (or at least to make things harder for them) that use email extractors to collect addresses from web sites. The script generates a random number of fake Email addresses and URLs that call itself in an endless loop. The result: email extractors get clogged with fake addresses. A META tag tells search engine robots not to index the page. To use just rename the file to anything you want (example: test.asp) and put a hidden link to it on your site, like this: [A HREF="wpoison.asp"][/A] (replace [] with <> respectively). Please help spread the word about web poisoning, it might not stop spammers, but will surely slow them down!
