I'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!

I have got a Dell RT7D60 Keyboard which has a built in Smart-Card Reader. I have developed an application in vb.net and wondering if it is possible to allow users to log on to this application using smart card Authentication.I want to keep the authentication simple like instead of allowing user to enter username and password to open the application, i would want the application to ask for example, "Pls insert your Login-Card" and get the info from the card to authenticate the user.I have no clue for how to begin. Is it too complicated to integrate it in the .net application.
View 1 RepliesI am trying to use a smart card reader in 2008. All I want to do is store a simple value to the card. Not really interested in forms of security.
Cannot seem to find anywhere to start on this one and am an absolute beginner. Any tips on this one would be most useful.

View 7 RepliesI'm trying to use certificates to sign documents. The first time that I sign, the OS prompts a dialog for user to set the PIN, but the next times it doesn't. For security reasons, I need that every time that I sign, the OS asks the PIN to the user.

View 1 RepliesWe 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'm creating a simple forms application where users can enter their details and save the information to a .ini file because I needed this for a simple game profile.

I need to read a value (and possibly adjust the value) in HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall key on both 32 and 64 bit systems.I've tried accessing 'stuff' by compiling my widget as both a 32 and 64 bit app, but nothing is working. Then I came across some information indicating that this could be done from a 32 bit applicaiton using KEY_WOW64_64KEY [URL] somehow, but I can't figure it out.
1) Check the existing value of HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall{ProductGUID}DisplayVersion handling both architectures.
2) If the value <> "" And <> Our Current Version Then
3) Write the Current Version to the value mentioned in step 1.
I wouldn't think this is that difficult as I've worked with registry before, but the 64 bit stuff is throwing me for a loop.It would be nice if I could compile my app to target AnyCPU then detect where its running on 32 or 64 bit. The app could then look and update in the appropriate location.I currently am set to use .NET 2.0, but could go to 4.0 if there is something in there that makes the above tasks easier.
