project im working on for my course,the idea is a photo printing machine that loads up 4 images if usb stick is checked and a different 4 if memory card is checked. and then whatever image is selected appears in the big picturebox on the left [URL] i have 2 print size options set as radiobuttons, radiobutton 1 = 6x4, which costs 25cent per photo, radiobutton 2 = 8x10, and is 50cent per photo.i also have a textbox which will display the number of copies to be printed So here's my dilemma, when the print button is selected alongside one of the radiobuttons i want it to display a message saying something like this "you have selected (whatever the amount of copies)of this photo sized 6x4, or 8x10 depending on which radiobutton is selected, and i want it to display the total cost which is the number of copies multiplied by the rate for the print size selected, then an option saying "Do you wish to proceed" Yes or No.
I did something similar to this in class earlier in the year but cant remember it, it was an airline booking program with 3 types of payment cash, visa or mastercard,upon booking a message popped up saying there is a certain percentage discount for using visa or mastercard

Is 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.

I wrote a program which has 4 different menus. Each menu does some kind of calculations by first read numbers from binary image file and then writes the output file. I was wondering if I could output or write to memory instead of outputting to a file.
If that is possible then I think I could do all with one click instead of using 4 different menus (or forms).

I have a class as follows:
Public Class Courses
Public CoursesOfferedMAIN As New List(Of Category)
Public CoursesList As New List(Of Course)
[Code]....
There is no problem with the code how ever, I would like to know, in the process I am following, the number of subjects, couses, examsets etc would all get repeated in the specific type lists like SubjectsList, examstypelist etc.. since they are being copied over it would take more memory.
Hence, my question or doubt would be, is it possible to use the same as references instead of copying them over to lists to save memory, or are there any methods better than this?

I 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).

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.

I'm basically making an app to take screen shots in a game as I chat. There will be a bit more to it later, and I will likely be using PNG but that is besides the point for now.Whenever I take a screenshot and save, doesn't matter If I am saving converting quality or using system.drawing directly, the memory use goes up about 1.5MB per save. I'm rather new to VB.Net so I can't really figure out why...as far as I can tell I release everything.[code]Ihave tried setting it to nothing with no luck, and aside from that memory slowly goes up per time Enter is pressed. I'm not sure why data would be saving to memory when Subs and Functions are supposed to release data after use?

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?

I have been looking all over the net trying to find a program that can read data from a USB CCID card reader.
after several hours and several pages of useless info i thought maybe there is a way i could create a simple progeam in VB to read the data, so i started another long search for info also to no avail.
Does anyone know of anything like this or if its even posable?

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.
