Credit Card Number Validation (VFP 6)
Steven Ruhl, CitiMortgage, Inc.
This is a VFP 6 version of my Credit Card Number Validation class. It uses the _assign method to make the class almost entirely property driven simplifying the interface. I have added an enhancement that allows you to decide what credit cards you want to accept. A sample form is included to allow you to easily test the class.

Description
WHAT'S NEW No functional changes have been made. This version corrects a problem with an include file reference. No include files are used in the class, but someone had a compile error where it wanted an include file from my application framework. That reference should be eliminated now. WHAT IT DOES: -Determines card type based on prefix. -Checks if number is of the correct length for that card type. -Verifies the check digit is correct. -Checks if card is in list of accepted card types. WHAT IT DOESN'T DO: -Obtain credit authorization from a clearing house. -Guarantee the credit card account exists, only that it is in the correct format and could exist. The following cards are supported and a provision has been made to add new card types for validation: VI - Visa MC - MasterCard DI - Discover AX - American Express / Optima DC - Diners Club / Carte Blanche EN - enRoute JCB - Japanese Credit Bureau ABC - Australian Bank Card
