INTEGRATING ONLINE CREDIT CARD TRANSACTIONS

This is the best reason to password protect your online content using AuthentiX. By integrating with preferred online credit card clearers , you canautomatically add students to your AuthentiX database once their credit card has been charged. The AuthentiX database is updated with the usersexpiration date, making it easy to manage and delete expired accounts.

But how do you accomplish this? Simply choose a script from one of our preferred online credit card clearers, install it into a script enabled directory onyour server - after you have arranged for service through the clearer, of course.

Here is a quick overview of how the integration process works:

1. The user goes to your website. In this case, they are not already a member, so they must purchase access to the online content. They click a link (usually'Buy Now') which provides them with an online purchase form. Your online credit card clearer will be able to give you a template of the 'purchase form'.

2. The user fills out the form with their information (including billing address and credit card information), and then clicks 'submit'. This process posts (aka'gives') the form to the online credit card clearer.

3. The online credit card clearer ensures that the information is valid, subsequently charging the credit card. Then the online credit card clearer posts theusername,password, and expiration date to the SubscriptiX integration script, which you have, by now, put on your website server.

4. Upon receiving the information (username,password, and expiration date) from the credit card clearer, the SubscriptiX integration script adds the newuser to the AuthentiX internal database.

5. The next time the user goes to the website, they will gain access by simply typing in their usernames and password (Cookie Based authentication doesnot require the user to enter in their username/password. They will be allowed access only if they have the correct cookie). When the expiration day comes,

their access status is changed within the AuthentiX database.

So what have we accomplished? Using AuthentiX, we have password protected our distant learning web content. Your students can change their ownpasswords, email forgotten passwords to themselves, and even pay for their classes online! Now you can focus on the most important part of your website- content development.

This article shows how to pass a string of text from a TEXTBOX server control to a routine that replaces words in the string. This is handy in replacing

words before they get committed to the database, email or where ever this text is being sent. A dataset is created to and uses the READXML method toread an XML file into the newly created dataset to compare the words.

Here is the code:
