smartcardio performance in Windows Vista problems

Hello

I have a Java Applet that access using smartcardio smart cards.

The cmdlet works in Windows 7, XP, Ubuntu Linux and MacOS 10.6 with no problems. However, in Windows Vista, it has serious performance issues. It still works and all the operations I need, no exception is thrown at any time, but, while in other systems of exploitation of all data on card operations takes 2 seconds in Vista, it takes like 2 minutes.

Any idea about it?

You have logging/tracing in your applet to confirm that the performance issue is during the show?

If this is the case, it could be many things. It could be the drivers for the drive. It could be the implementation of smart card services in Vista. It could be the version of PC/SC (winscard.dll) in Vista.

You can try to use a native tool to send the crude APDU on a map (or even a simple Java test harness) to see if it is related to the race as a both applet and to refine the where the problem is.

See you soon,.

  • Windows VISTA problems with ".exe" files

    I'm on Windows Vista Home Premium, 64-bit, SP2 on a HP Pavilion desktop computer. Recently developed a problem when you try to run any file with an ".exe" extension results in a window asking to "choose the application I want to use to open the file" or "this file has no program associated with it for performing this action. Create an association in the control panel to define the Associations. " Any ideas?

    This problem occurs when your .exe file associations are broken. This is usually caused by a virus/malware that changes the default file associations in Windows. Follow these instructions to resolve this problem:
    Download exeHelper from one of these two links: link 1, link 2 double click on exeHelper to run the fix. A black window should appear. Once the patch is finished, press any key to close.

    If the above does not work, try to make a Bootable ERD to do a Startup Repair:

    As is the case with most computers/laptops these days, they do not come with good Vista disc to repair only the recovery disks.

    As your falls into the above category: download the ISO on the provided link and do a repair of the disc.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

    You can make a tool to restart system, System Restore, etc. with it.

    Read all the info on the website on how to create and use it.

    There are different methods to reinstall Vista, if you think it is necessary to do so.

    This can help you:

    http://www.heidoc.NET/Joomla/technology-science/Microsoft/57-Windows-Vista-direct-download-links

    You can contact your computer manufacturer and ask them to send you a set of recovery disks.

    They should do this for a small fee.

    To reinstall Vista using their recovery disk/s, you start from the 1st recovery disk they provide and follow the manufacturer's instructions to reinstall:

    You need to change the Boot order to make the DVD/CD drive 1st in the boot order:

    How to change the Boot order in BIOS:

    "How to replace Microsoft software or hardware, order service packs and replace product manuals.

    http://support.Microsoft.com/kb/326246

    And if you have never received a recovery disk when you bought your computer, there should be a recovery on the drive Partition hard reinstall Windows how much you bought your computer.

    The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)

    Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.

    Ask them to the proper key sequence.

    And if you do not score a manufacturer of recovery on your hard drive, you should be able to make your own recovery from her disks to reinstall the operating system.

    Go to programs > name of the manufacturer of your computer > then their system or recovery tools software topics for them, depending on how it is formulated.

    If you can't find any reference to it, contact the manufacturer for advice on how to make these recovery disks.

    Some manufacturers have more available Vista recovery disks.

    If this happens, you may need to try this instead:

    You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.

    Other manufacturers recovery DVDs are should not be used for this purpose.

    And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs

  • Windows vista problems install keyboard and mouse

    I try to install windows vista ultimate on a new amd system I've built recently. The windows vista screen Boot starts well, but I can't go further with the installation because the keyboard and the mouse do not work.

    To solve the problem, I booted up with a Linux distribution and I can use the keyboard and mouse and everything works fine. Initially, I bought vista using boot camp on my Mac and the keyboard and mouse work well with vista on this configuration.
    I want to upgrade to windows 8 thereafter, but I might need to buy the whole program, rather than the update if I can't do vista works. I don't want to spend money if I can't because I'm broke. Any suggestions?

    Parameters of the BIOS of some computers have a setting "Enable USB Legacy" to allow the keyboard to work without Windows running.

    If you have PS/2 ports buy an adapter or a PS/2 keyboard. Most USB keyboards can be connected to a PS/2 port using a USB to PS/2 adapter.
