Code For Magnetic Stripe Writer?
Sep 29, 2009
my company provides security card for certain seller agents that sold our products to customers. they need to claim their point or login through PDA application by scan barcode or swipe magstripe (magnetic stripe). i had written the code for barcode scanner, and i had written the code for magstripe reader, but it didn't need any comm control at all. all i had to do was focusing on textbox that showed data had read.i had device to write data, it is MSRE206 with serial port. now i need code in VB to write data to magstripe. i didn't have any experience with comm control in VB, so i didn't know where i have to start?how to write a program in VB so that i can write data to a magnetic stripe on cards?

I need to be able to print ID cards with magnetic stripes. This is a simple matter of putting special code characters in the text to print. I can print text to the card printer from Notepad, and the printer knows to encode the stripe. This even works printing from a report in Access, but not from a Crystal report from a VB.NET app, and not from the PrintDocument object. All these do is print the information to be encoded on the front of the card. So I need to be able to print these from a VB.NET app, but not using CR or PrintDocument.

First off, what I'm doing here is trying to read in information from a magnetic stripe card, parse it, validate certain parts and go from there. I'm working on two classes... the first is CardClass and that represents the card itself (well, the data obtained from the card). The class is CardParsingClass. This holds all the card parsing rules.
At one point in the process, I will create an instance of the CardClass. That instance gets passed into the CardParsingClass.ValidateData function:
CODE:
This function steps through each of the card parsing rules and applies the rule to cardCurrent to see if it passes (i.e., is valid).
And here we come to the meat of it.... what I'd like to do is define an event called FailedCardReadEvent. Whenever I raise the FailedCardRead event I could write to the log that it failed, modify variables in the CardClass (particularly the state of the card read variable), etc. So, the way I'm looking to use this would be something like this:
CODE:
So as shown above I'm thinking I should code a FailedCardReadEvent in the CardClass. But I don't know how to do that.
I also don't see how this is different than just calling a subroutine. If I have to manually raise the FailedCardReadEvent isn't that the same as calling a subroutine?
I know I'm missing something but I'm just not getting it. I've spent some time googling this morning and read a few things but I'm just not understanding how it all works.

I'm having some issues with my MSR after it reads that data. I can find the device and read the data without any issues. When I try to do anything except message box the data, the code hangs without erroring out. What I'm trying to accomplish is that on each swipe of the MSR, a MDI child form is created. I get nothing when I try to create a new child or a new form from the DataEvent of the MSR.[code]

Is there a control in .NET that allows you to create boxes with input and output pins which can then be connected? A good example is Graphedit

I 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.

I 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?

This is my code at the moment (produces error)
tc1.text = Math.Atan2((Math.Sin(lon1.Text - lon2.Text) * Math.Cos(lat2.Text)), Math.Cos(lat1.Text) * Math.Sin(lat2.Text) - Math.Sin(lat1.Text) * Math.Cos(lat2.Text) * Math.Cos(lon1.Text - lon2.Text))) 2 * pi)

is it possible to print over a form instead of using a type writer (printing the text in a text box on the correct fields or blank lines)? my attempt i measure the x and y coordinates of the fields where the printer should print the text in centimeters by placing a scale on the form paper and taking the top left corner of the paper as the origin
i fed these x and y values measured with a scale to my vb .net program which:subtracts the height of the font from the y value (assuming the printer prints the topmost pixel of the character first)
and also converts the the centimeters to inches and multiplies them by 100 but when i print these fields over the form they are printed at wrong x and y coordinates for time being i adjusted the values (by trial and error) for 1 particular form but i dont want to do this for every form!!! what am i missing in my calculation that is making the printer print at wrong x and y coordinates?

i am creating a program which scans and saves images. in my program i have the option to save images and with each image i save it gets its own number for example: file1, file2, file3, file4 and so on. the only problem i have is getting the prgram to remember where it left off so it carry's on the number. my understanding is that i need to create some sort of stream writer or file stream class for this proccess to work. so it save's the last image number i was on, and carrys it on next time i open the program up again. and i also need it to re-write the new image number its on for next time. so i need to write and read the text file (.txt) and write it again if you catch my drift? i have a book to help but the wording in it is so confusing at the min, i m lost where to start.

The bigger problem is that I can't seem to get everything involving using stream writer and reader working. If I start of with a .txt file already correctly formatted then I can display it in the list box. But adding data during run time is not proving successful.

I've Googled this for a long time but I haven't come across an answer...or I didn't realize it if i did. I need to create an advanced clipboard that will allow you to save 50 phrases for later use. It will have 5 tabs, 10 phrases on each tab with a button next to each phrase to copy. So, the user will open the program; click the appropriate tab then click the button next to a phrase to copy it to the computer's clipboard so they can paste it somewhere else.

I was able to code a sub that opens a StreamReader and Writer. The Reader reads a *.txt file and the Writer modifies it line by line as it's entered into the memory then writes it to a temporary file which is then copied over the file that the Reader read.
The problem is that the StreamReader and Writer seem to fail to close.At first when I tested it I would get an error stating:
Object reference not set to an instance of an object
I put breakpoints in the sub to figure out where it's erroring out and it's erroring out when it does sr.close() and sw.close() (Reader/Writer.close())Here's the code for the sub. Maybe someone can tell me what I did wrong.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
If pDebugMessages = True Then MsgBox("Stream Reader/Writer initialized.", MsgBoxStyle.OkOnly, "Debug")

I have a dataGridView and tied it to a button that saves every time you click it. and every time you click it, I want to write a line to a txtfile that displays how many records were changed and the date that they were changed. Everything works fine but every time a save has been made it over write the previous entry on the text file. Here is some of the code.
If changes > 0 Then
MessageBox.Show(changes & " changed rows were stored in the database.") ' changes shows how many entries were changed
swDate.WriteLine(changes & " record changes on " & entryDate) 'entryDate is formated as date with value of "Now"
Else
[code]....
I am getting the right results in the text file except it over writes previous entry's so there is only one entry saved in the text file at any given time. I want it to keep building the text file so every time something is streamWrited the previous things in the text file stay there and it add to it. Looking at my problem I cant really justify or implement a For Each..Next or a Do While..Loop. My vb knowledge is limited so go easy on me.
