View 1 RepliesI 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.

We 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.

View 1 RepliesI want to do in vb.net what I would have done in SQL with the CHARINDEX command. That is, I want to interrogate a string and ask, 'Does this string contain a hyphen? If so, whereabouts in the string is it?' I tried Googling this but as with a lot of things in vb.net, there's always a million different answers given with each response seemingly trying to overcomplicate the issue and out-code the previous one. Hence my confusion.
View 5 RepliesIs 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 2 RepliesI am trying to write a code that will byte swipe data in a string.
The conversion should take a 16 characters string, and swipe the first to characters with the last two, then characters three and four with character thirteen and fourteen and so on, in this format if the input string is
A1B2C3D4E5F6G7H8 then the converted sting will be H8G7F6E5D4C3B2A1.
I run into problem using: left(mystring 2) and right(mystring -2) because the string to manipulate is an input of a textbox so I fail when I try to use cross data with a StringHandling class, and how to incorporate StringHandling into my form class and without it when I try something like
Dim byte1 As String = Left(MyString, 14)I get an

View 9 Repliesi just purchased a magtek barcode scanner which you can swipe a credit card or id card through. It connects via USB which was plug in ready and is acting like a keyboard. Therefore i didnt have to create any barcode class library or anything like that. Currently i have my program focused on the textbox in which i want the data to be placed and that is also working correctly. When i swipe a card it populates the textbox with data and pulls the customer's record. Where i'm stuck is i don't know how to tell if there was a physical swipe of a card but the barcode scanner couldn't read it. So that i can have an error message pop up stating that my program couldnt read your card.
View 3 RepliesI have been looking for like 3 hours trying to find a dll or anything to make a simple cards game, but everything I find is oriented to C.
In this page A FreeCell game using Cards.dll - CodeProject� they talk about just what I want, but I cannot make it work in Visual Studio 2008 using Visual Basic.net, I don�t know if that has anything to do with the Vista OS I am using.
In the page I mention the author says "There are many good articles on the net on how to use the Cards dynamic link library" and I am sure the good articles are there, but my good luck has make me looping around the same nonsense results so I end up with nothing after 3 hours search.
The game I want to make is just something for a project we must do in class, how to start making a cards game fast and simple. If someone knows about a cards dll that works fine with vbnet, that someone would be my new hero.
I have a multi input capture card (Composit, s-video, ...) and I developed a program with avicap32.dll in vb.net to connect to a webcam. But I can not use this program to connect to composite input of my capture card.It seems the capture card has a default input.
Firstly, How can I change the default input? because I want to connect to compsite input.
Secondly, is there another way to connect to my capture card?
I've been googling but I could not find any code for vb.net or C#.net. They are all in C++ and I could not traslate them to vb.net
I am trying to make a card game which can be played over the internet between users. I have already downloaded the cardGame Starter kit for Visual Basic. I plan to modify it to the game I want.I had worked with Sockets (Client-Server App) a long time ago for a small chat program for computers connected in LAN.I had the following questions:How should I start off with this Application, should I first just concentrate on making the game and then progress to trying to figure out how to make it playable over the internet?
Or should I do it the other way round?Can I attain my objective using Sockets? or do I have to use something else?Is there a tutorial available to start me off? (I Googled and "Bing"ed it but to no avail)
