DosBank is a "shareware program" and is provided at no

|
|
charge to the user for evaluation. Feel free to share
|
||
|
|
it with your friends, but please do not give it away
|
||
|
|
altered or as part of another system. The essence of
|
||
|
|
"user-supported" software is to provide personal
|
||
|
|
computer users with quality software without high
|
||
|
|
prices, and yet to provide incentive for programmers
|
||
|
|
to continue to develop new products. If you find this
|
||
|
|
program useful and find that you are using DosBank and
|
||
|
|
continue to use DosBank after a reasonable trial
|
||
|
|
period, you must make a registration payment of $17.95
|
||
|
|
to Joe Maguire. The $17.95 registration fee will
|
||
|
|
license one copy for use on any one computer at any one
|
||
|
|
time. You must treat this software just like a book.
|
||
|
|
An example is that this software may be used by any
|
||
|
|
number of people and may be freely moved from one
|
||
|
|
computer location to another, so long as there is no
|
||
|
|
possibility of it being used at one location while it's
|
||
|
|
being used at another. Just as a book cannot be read
|
||
|
|
by two different persons at the same time.
|
||
|
|
|
||
|
|

|

What Is DosBank?
|
||
|
|
|
||
|
|
DosBank is a Credit Card validation program developed
|
||
|
|
for individuals and companies that take credit card
|
||
|
|
orders over the telephone without any immediate means
|
||
|
|
of verification.
|
||
|
|
|
||
|
|
The program has saved our company thousands of dollars,
|
||
|
|
and will do the same for yours. This version of the
|
||
|
|
program is laid out in a data entry format, but can
|
||
|
|
be adapted to any enviroment you run under. For you
|
||
|
|
programmers out there you can pass a parameter to
|
||
|
|
Dosbank and have it return a code, you can then in turn
|
||
|
|
read that code back into your own program. Details of
|
||
|
|
this feature are described below.
|
||
|
|
|
||
|
|
The program has a number of options from displaying a
|
||
|
|
message telling you if the card is good or not, as well
|
||
|
|
as telling you what type of card it is, MasterCard,
|
||
|
|
Visa, American Express or Discover.
|
||
|
|
|
||
|
|
Installation:
|
||
|
|
|
||
|
|
"CCARD.EXE" (the main program), "LOAD.EXE" (Beginning
|
||
|
|
screen) and all other "DosBank" files can be put into
|
||
|
|
the directory of your choice. If you wish to run the
|
||
|
|
program from anywhere in your system, you need to put
|
||
|
|
that directory into your path. For best results always
|
||
|
|
run "LOAD" from the same directory ALL of the other
|
||
|
|
files are in. "LOAD" is NOT required for the program
|
||
|
|
to run properly, it only shows a PCX file and is a
|
||
|
|
prelude to "CCARD".
|
||
|
|
|
||
|
|
Once you have completed the above DosBank is ready to go
|
||
|
|
|
||
|
|
To start Dosbank you can run the "LOAD.EXE" startup
|
||
|
|
screen which will lead you into Dosbank, or you can run
|
||
|
|
"CCARD.EXE" for an immediate entry into the program.
|
||
|
|
|
||
|
|
Instructions:
|
||
|
|
|
||
|
|
1. Entering a Number: There are 2 ways to enter a
|
||
|
|
number into DosBank. first you can just type it in
|
||
|
|
normally and hit the <Enter> key and it will
|
||
|
|
validate that number. Secondly, you can use your
|
||
|
|
mouse and select the numbers individually by using
|
||
|
|
the "Number Pad" provided with the program, and
|
||
|
|
select the "Green" <Enter> under option one.
|
||
|
|
|
||
|
|
2. Verification: Once you select <Enter> the program
|
||
|
|
will display the results of the verification.
|
||
|
|
|
||
|
|
It will display a CYAN sreen with a message saying:
|
||
|
|
|
||
|
|
Valid <Card Type> Number
|
||
|
|
|
||
|
|
Card Type will either be Visa, Mastercard, American
|
||
|
|
Express or Discover. If the Card number did not
|
||
|
|
pass the validation process then you will get a
|
||
|
|
message saying:
|
||
|
|
|
||
|
|
Invalid <Card Type> Number
|
||
|
|
|
||
|
|
and the screen will turn red.
|
||
|
|
|
||
|
|
3. Command Line option: You can pass a parameter to
|
||
|
|
Dosbank via the command line. Example:
|
||
|
|
|
||
|
|
"CCARD 6666666666666"
|
||
|
|
|
||
|
|
"CCARD" being the program name, and
|
||
|
|
"6666666666666" being the Credit Card number.
|
||
|
|
|
||
|
|
The Command Line option will return 1 of 5
|
||
|
|
different options, with 2 of those options the
|
||
|
|
Credit Card company will be displayed, those two
|
||
|
|
options are Passed and Failed. The following are
|
||
|
|
the result codes:
|
||
|
|
|
||
|
|
"1" - Program Error:Can mean it was
|
||
|
|
Program, User or Number produced
|
||
|
|
|
||
|
|
"2" - Followed by Credit Card Type.
|
||
|
|
This means the number passed
|
||
|
|
validation process.
|
||
|
|
|
||
|
|
"3" - Followed by Credit Card Type.
|
||
|
|
This means the number failed
|
||
|
|
validation process.
|
||
|
|
|
||
|
|
"4" - The number entered did not belong
|
||
|
|
to a Major Credit Card Company.
|
||
|
|
Could not process.
|
||
|
|
|
||
|
|
"5" - Invalid Number: Main cause of
|
||
|
|
this error is length of number
|
||
|
|
passed to program. The number
|
||
|
|
should be between 13 and 16
|
||
|
|
characters.
|
||
|
|
|
||
|
|
The first character of the return code will always
|
||
|
|
be a 1-5 so you can write your program accordingly.
|
||
|
|
If the number passes or fails you can always count
|
||
|
|
on the Credit Card company to be displayed along
|
||
|
|
with the result code.
|
||
|
|
|
||
|
|
If you were to pass the number to DosBank from
|
||
|
|
the example above, the resulting code would be
|
||
|
|
returned:
|
||
|
|
|
||
|
|
"2 Discover"
|
||
|
|
|
||
|
|
"2" Meaning passed, as described above, and
|
||
|
|
"Discover" being the Company that issued the
|
||
|
|
Credit Card.

Program Information:
|
||
|
|
|
||
|
|
This program was written in QuickBasic v4.5
|
||
|
|
|
||
|
|
This Program was written by Joe Maguire, a
|
||
|
|
Programmer/Analyst for a Support company in
|
||
|
|
Florida.
|
||
|
|
|
||
|
|
Source Code Information:
|
||
|
|
|
||
|
|
The source code is available and can be purchased
|
||
|
|
while registering this program. The Source code
|
||
|
|
costs $67.95 (Including Registration), and
|
||
|
|
enables you to adapt the program to your specific
|
||
|
|
needs. In my example earlier, I've adapted it so
|
||
|
|
I can call it and it will return a code to the
|
||
|
|
clipboard telling me whether it passed or not.
|
||
|
|
|
||
|
|
If you don't have a programmer on staff, or don't
|
||
|
|
have one that writes in QuickBasic. I can also
|
||
|
|
quote you on what I would charge to write it into
|
||
|
|
your daily procedures for you. Just notify me at
|
||
|
|
the address above and I will contact you
|
||
|
|
immediately.

||

|
||

|
||
|
|
for Windows, and can purchased for the same
|
||
|
|
