Reading ASCII Data From Magnetic Swipe Card Reader?
Sep 27, 2011We have the customers credit card number on file which we use simply to identify them when they swipe at our computer. The problem i'm running into is that when they swipe their card in the card reader (Magtek mini usb) it outputs the data as ASCII which looks something like %B followed by the credit card number in whatever textbox i have the program focused on. I'm sure i could just search the textbox for any 16 character number string and assume that is their card number, but i was just curious if there is some best practice to decript the ASCII output from the magnetic card reader.

Jun 23, 2009I've implemented a program that read/write data from a Smart Card. I noted that the reading/writing operation are slow (2 or 3 seconds, nothing for me, but during which I've noted that common users ar lost!).
So, I've thought to insert a progress bar to show the duration of these operation... but I don't know how to start on using of the progress bar in vb.net!

View 2 RepliesCapture Raw Signal From WiFi Card As Would A Sound Card
May 9, 2012Is it possible to capture the raw signal from a WiFi card in the same way you can capture the signal from a sound card? (I already found code for working with a sound card and for drawing spectrograms) I'm wondering because it would make a cool radio-type project. I'd prefer a solution that integerates well with .net (VB or C#).My basic goal is to capture the ambient radio waves and build a primative "telescope" of sorts. Using the built in computer hardware is just the easiest way to accomplish this. If you have any other suggestions about how to accomplish this goal in a different way please post it as an answer also.

View 1 RepliesEID SDK - See If Card Inserted Into Reader Then Read Out Data
Mar 14, 2010I am trying to use the eID SDK (for using the belgian ID-card) in VB. It's supported but I can't get it to work. I have never worked with sdk's before. I did manage to get it to work in c++ in console but I really need it in visual basic. Also the VB examples that come with the sdk are made in an older version of visual studio and when my version tries to convert them they don't work. I want to use the sdk to see when a card is inserted into the reader and to read out the data. (both i got to work in c++ console).
View 2 RepliesGetting Data From A USB Magnetic Swipe Card Reader
Jun 18, 2009I am working on writing a program that once a magnetic strip card is swiped, the number on the card is validated against a database storing information on the user. What is the best was to get the stream from the USB swipe card reader, build by Magtek, and then just pull the 9 digits I need? I have currently been using an Excel macro that searches the Excel document, but I want to get away from this system and make it more user friendly.

View 6 RepliesUse With A Textbox In VB Swiping A Card With Magnetic Encoded Data?
Feb 15, 2012I have created a program in Visual Basic using Microsoft Visual Studio 2010 Professional. There is a textbox that I use in the program that when the focus is placed on it will take the data encoded on a magnetic striped card such as a driver's license or any card that has this kind of data encoded magnetically. Very simple to get the data as the program takes all of it upon the swipe without having to do really anything, however, the problem is that I don't know which declaration to use when the swipe has stopped - or the last character has been entered. Currently I am using TextBox1_textChanged as my declaration, but that is called every time each character is put into the text box. When you are swiping, this is an ongoing process until the last character is put in. So if I have a magentic card with 10 characters in it, this method will be called 10 times. Is there a declaration that I can use that only fires off whent he swipe has loaded all of the characters or some kind of loop that I can incorporate?

Data Binding - Update The Grid Data By Reading The Array
Apr 2, 2012Data binding should be an extremely simple thing to manage but I can't find a SIMPLE solution to the following problem.
I have two forms
Form1 contains a 4x4 MSFlexGrid (unfortunately an unmanaged COM object but I can merge cells, which I can't do with a managed Datagrid)
Form2 contains other controls which change the data in the Flexgrid.
I connect the two with a Public 4x4 array. Form2 changes the data in this array. I can update the grid data by reading the array. But how do I bind the Grid to the array so that it auto-updates - which is the whole point of binding isn't it?
