Coding Keyboard Magnetic Card Reader


I'm developing a POS system that I'm integrating with a credit card verification software. Has anybody integrated a keyboard magnetic card reader with VB? The trick here is to always set focus on a text box. This text box will capture any data scanned in. I thought about using a timer to set focus into a text box. Is there a better way?

Thanks

Reloadable Card Using Magnetic Strip
hi guys! were having a thesis and its about a reloadable card which can be use in a gasoline stations in refilling a fuel. here it is.. its like a (TIMEZONE CARD) you can reload any amount on the strip, since our knowledge about VB is limited we are having a problem in the programming..
1. how does vb store information in the magnetic strip?
2. how can we input the amount on the strip?
3. lets say, the amount was stored.. and the card has been swiped in the reader.. it should display the available amount in the card and then automatically-debit it.
we have no idea how to do all of these stuffs.. we would appreciate any help coming from you guys, especially from the leaders of this community.. thnx!

Magnetic Debit/Credit Card Readers
I am looking to add the ability for my customers to process Debit/Credit Card transactions through my application. I also need to have some sort of keypad so that the customer can enter their PIN number. One of my customers wants to get rid of their Credit Card processing machines. I was wondering if any one else has added this functionality to their apps. If so, what reader did you end up using, etc.

Thanks!!

Tarot Card Reader
Here's my first attempt at a tarot card reader. There are still a lot of features I'd like to add, but I'm tired of working on it and thought I'd give it a rest for a while.

The one technical thing I'd like to fix is that the second card (RECT) is supposed to be turned 90 degrees. I'm too busy/lazy right now to dig into the math to make that work.

Future features (try saying that 3 times fast) include a splash and config screens, background music, different layouts, and an A.I. feature that can take the reading of all the cards and come up with a single comrehensive reading. (Actually, probably more like a Knowledge Expert program than Artificial Intelligence)

I have no ego in this it's just how I have fun, so I'm open to feedback: good, bad, and ugly.

P.S. I have the bitmaps for the large card displays but, unfortunately, they add up to 37MB . Maybe I'll have to redo this with JPGs someday.

Enjoy!

Credit Card Reader & Code
I've written a rather large program to manage a winery sales, inventory etc. The missing link in the program is the ability to read a credit card in a reader and have it absorbed in the program. I now have them enter the data manually and store in a database.

I have no knowledge regarding the readers and code. Can anyone steer me in the right direction or give me some guidance?

Control Of A PCCARD (PCMCIA) Card Reader
I am developing an application that reads data from a Flash card. The card requires you to open the PC Card (PCMCIA) Properties window, select the slot that the card is occupying, and "deenergize" the card before safely removing it. I have searched the MSDN library and found some information under a search "Card Services". According to that there is a card services API. I cannon find it in the Win32Api.txt file. I am new to API's, so any help with this matter would be great!

Coding - Setting Up Check Digit For Credit Card
I'm a newbie, taking my first VB class now. My assignment is as follows:

Take a 5 digit number
multiply every other number x 2 (digit 2 and digit 4)
get result
sum all digits
take the last character of the sum (ex sum = 26, use digit 6)
add that back to the original number and display a 6 digit number.

All of the calculating should be done in the background and only the 6 digit number displayed in the uiNumberTextBox.

I think I'm okay up until the bolded/italics items - they have errors, but since I'm new at this I have no idea how to fix them..
How can I go through the debug process and have VB tell me where the first error is? And, what am I doing wrong?

I know on the final result, where I'm needing it to display a 6 digit number - I'm not doing it right. I do not want to actually add the numbers just display all 6 numbers. I tried using val - but that didn't work either.

Private Sub uiValidateButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles uiValidateButton.Click
Dim characters As String
characters = Me.uiNumberTextBox.Text

Dim results As Integer
Dim char1 As Integer
Dim char2 As Integer
Dim char2a As Integer
Dim char3 As Integer
Dim char4 As Integer
Dim char4a As Integer
Dim char5 As Integer
Dim char6 As Integer

char1 = characters.Substring(0, 1)
char2 = characters.Substring(1, 1)
char3 = characters.Substring(2, 1)
char4 = characters.Substring(3, 1)
char5 = characters.Substring(4, 1)

Dim number As Integer
If Me.uiNumberTextBox.Text.Length = 5 Then
'perform calculations
'multiply every other number by 2
char2a = (char2 * 2)
char4a = (char4 * 2)

'sum the numbers
results = char1 + char2a + char3 + char4a + char5

'take the last digit of the sum and append to original number
results = results.Remove(0, 1)
'result - display 6 digit number in numbertextbox
Me.uiNumberTextBox = char1 & char2 & char3 & char4 & char5 & results Else 'display error message
Me.uiIdNumberLabel.Text = "Entry must be a 5-digit number."
End If
End Sub

Any/All help would be greatly appreciated!

Magnetic Forms
I decided to work up an example of how to make forms magentic, ala Winamp, using subclassing.

I got the thing working pretty well, the only problem I'm having here is that there is a flicker when the magetism comes into effect, and I can't seem to figure out how to get rid of it.

I have attached the project here. Anyone got any ideas?

Magnetic Docking
Out of all those docking techniques, I need a very "professional look" type docking that includes magnetic. I need it to be very soft, which perhaps a line that connects once docked. I've had some very rough docking that sometimes doesn't actually connect but stays at a window thats not even my own program. If anyone has any examples please say so. Otherwise, I have code that has very rough docking, and maybe you can fix that up and make it smooth, I'll post it below...

Thanks,

Brawl Card Game In VB (Card Deck Questions)
I wanted to make a TCP/IP online version of the card game Brawl by cheapass games.

I have some general questions, as I've been a VB programmer for 2-3 years, but haven't done much (anything) with game programming, or objects. (I was taught in college procedurally, so my Object creation isn't what is needs to be in my opinion.)

The short explanation of brawl (card-questions to follow) is this...

2 Players each with a 35 card deck which consists of the following cards:
Bases: Use to start a pile
Hits: (coming in 3 colors Red, Green, Blue)
Blocks: (also in the 3 colors) These stop your oppoent from playing anymore hits on a pile
Press: (3 colors) counters the effect of a block
Freeze: Freezes a pile

You have up to 3 piles (which must start with a Base Card, the base card can only be played if there are less than 3 piles), and then play Hits on your end of the base in hopes of getting more hits on the base than your opponent does. Once a pile is frozen, you count up the hits, and whoever has more wins the base.
Whoever wins more bases, wins the game.
Blocks will prevent the opponent from playing any more hits on that pile. (can only be played on a Hit)
Presses will undo the effects of the block (can only be played on a Block)
So you have up to 3 piles to play on, and each player has a discard pile (which they can play the top card of, instead of the top card on their deck).


Ok, now the questions...

I have a Card Class which has:
Color: (red, green or blue)
Type: (hit, block, base, press, freeze)
Number: The number of this card in the deck. You may have for example, 8 Blue Hits, 2 Red Hits, 4 Green Hits, 2 Bases, 2 Blue Blocks, 1 Blue Press, etc.

Deck Class which has:
Array of Card (1 to 35)
Current: Pointer to the array slot holding the top most card.

Is the right way to do the deck really an array with a pointer? I'd need a Deck class for the Deck to draw from, an initialy empty deck to use as a discard pile as wel.

I was debating making the deck class in a collection instead of an array, but you really won't ever have more than 35 cards in the deck.

Now for each of the 3 piles, you could theoretically have between 0 and infinity (if I allow more than 2 players to play).

Comments?

How Can I Retrive The Infomation Of A Video Card & Sound Card?
Friends,

Is there any possibility to retrive the information of a Video Card & Sound Card? Please help.

Determining Credit Card Vs. Debit Or Check Card
There are many functions available that implement credit card identification
and number validation -- meaning you can decide, based on the number, if a
card is a MasterCard or Visa and if the number passes the Luhn Formula or
MOD 10 algorithm for the checksum. What I'm looking for however is the
scheme to determine is a card is a check or debit card versus a credit card.

Anyone know if this can be done by examining the account number pattern?

Thanks,

'Magnetic' Forms... Can't Find It Anymore
Hey,

Some time ago, I saw an example of "Magnetic" forms... Someone made it and I believe it was posted on this forum.. although Im not completely sure...

It had two forms (not MDI or whatever) and if you moved one close enough to the other they snapped together and moved as one.

I downloaded the example some time ago, thought it was cool but saw no use for it so I deleted it again. Now however I need it badly!

And I can't find it anymore... Searched for magnetic forms, docking, etc etc etc but I just can't find that example...

Anybody know what I'm talking about? Any links?

Emulating A Keyboard Button(VB Help Relating To Keyboard Events)
Hi There,

Does anybody know of a way to make the computer think as though a button has been pressed on the keyboard?
e.g. the user press's the delete command button on my form and it sends a message to the computer thinking that the delete key has been pressed.

Any help would be greatly appreciated!

Thanks.

Virutal Keyboard Emulating Real Keyboard Keypresses
I created a virtual keyboard (ie: keyboard Form2) which can be displayed by the user in which they can click on certain keys with the mouse and I can tell which character they have clicked on. Is there a way to have my other Form1 process these keypresses as if they came "from a real keyboard".

I realize I can simply pass the KeyCode/Shift values into the KeyDown event of Form1(which has KeyPreview=true) for it to process the characters entered, however, certain characters like Tab/Arrow keys (which the OS uses to move around the controls on Form1) will not get processed the same way since they were not generated from input from a real keyboard. I really do not want to emulate what the TAB key does via code, I would rather like to somehow make the code believe the keyDown event came directly from a keyboard input.

Did this make sense .... kind of hard to explain......?

In a nutshell, how do you make a virtual keyboard act exactly like a real keyboard (ie: so all keys which are clicked on the virtual keyboard would be treated the same way as if they were entered via a real keyboard)?

Virtual Keyboard - Assigning Keyboard Functions
Hi

I need to create a "virtual keyboard" in VB which has many of the controls of a real keyboard (it will be mage from VB buttons). The keyboard is purely for controlling the actions on a text box. Adding the letters (i.e. a string) is not a problem, however some of the functions I can't seem to fathom. I especially need to know how to assign a button to move the cursor left and right within the text box, and other functions such as backspace, delete and shift. Is the right way to use the ASCII codes for such keys?

I'm lost.

Thanks in advance.
