VISA does not open COM port

Hello, I made a simple VI which gets data from the PC com port.

It works well on my desktop but today for the first time I ran it on my new laptop and it does not show the COM port. I see the COM port in Device Manager, but it does not appear in the drop-down list in my VI. Can someone please? I have attached my VI.

Thank you

You use a labview 2013? I had a similar problem and I had to install NI-VISA so that it displays. Not sure if you have installed that, but if not, then that should solve your problem.

  • CD drive does not open and the light does not work

    original title: single CD player problem

    The problem with my CD player seems to be unique I can't find an answer, or someone else with the same problem online.

    My computer is custom built, the CD player lasted me 1.5 years no problem, not until one day I realize, it does not open and the light does not work on it, I ordered a new drive and installed that one, still does not work. so, I replaced the SATA cable which connects to the motherboard, still does not.

    When I go to my computer the drive appears but when I right click > eject it says: "year error occurred while ejecting CD drive D".  It also appears in devices such as SCSI CdRom Device Manager but I am not sure if it's actually my CD player.

    I also tried troubleshooting http://support.microsoft.com/gp/cd_dvd_drive_problems and no solution.

    WTFFF ideas? I really hope that its not the motherboard

    There are two cables you need to connect to the drive, one for data and one for power.  You must connect both training at work.  If you only have the data cable is plugged and not cable power which would be a possible cause of the problem that you see.

    "Ryanb1290" wrote in the new message: * e-mail address is removed from the privacy... *

    Sorry, im just of knowledge about computer hardware.  you say that I should try a different agreement or another port to plug in?

    I tried to connect on a couple different SATA ports on the motherboard.

  • Programs suddenly does not open!

    I have Vista 64 on a Pavilion laptop. I'm at work and I don't remember the number of the product, but I'll put up later.

    I wasn't too sure if it's in the legal issues section, if not can someone please point me in the right direction? Anyway.

    Laptop starts normally, it seems to connect to my account normally too. However, many programs wrong, including things like

    • All Microsoft Office programs (so I can't make it work)
    • Any Antivirus
    • Multimedia players
    • Internet browsers
    • Just about everything

    Curiously some programs open, especially those that came with the operating system as

    • Calculator
    • Paint
    • Notebook
    • Various programs from 'Windows' like, Movie Maker, Photo Gallery etc.
    • System Restore and other system tools
    • Control Panel stuff
    • Also Comodo firewall still works

    I can also browse through my thin computer, look in My Documents etc, but I can't just DO it from there. I can also connect to my home wireless network, but just cannot be used because the browser does not open.

    Here is some information that might be pertinent.

    It has happened three times now, after 3 weeks, then 2 weeks before that and about 1 month before that.

    Whenever I was too busy to spend time to understand, so I formatted just because I can't afford to leave my laptop off

    Using the system restore has worked the 2nd time, but also caused Firefox Act up, so I formatted in any case

    The other three times he didn't solve the problem, so it's not a Windows Update or the new program?

    In Safe mode, the programs WORK, but nothing increase analysis antivirus (Avira, Comodo, AVG, Avast, I do not run them at the same time I have them right)

    It always happens after that I restarted my computer. I reboot only every week or so. Its works fine, I restart and then nothing works.

    While the opening of programs to see who would work I got a blue screen after opening Notepad, something MEMORY_MANAGEMENT

    I don't know if this is related, but for the last month or so a certain IP using various ports trying to get connection with my laptop. I have the reject, but he made several attempts per day. He may have been doing this for more than a month, but I have him possibly accidentally allowed too before. Also after formatting on 35-40 GB my drive hard 250gig is mysteriously occupied (i.e. all files on C: add up to 40 GB less than what my computer c: a space for). Someone somehow destroyed my computer?

    You have been violated.  Prevent your ISP and follow their instructions.  If you have the time and the IP addresses of the intruder, the ISP might be interested.  I recommend a wipe and load.  If you have a router, reset it and change the admin password.  Access admin external locking.  Wireless should be a WPA2 encryption and access through the pool of MAC.

    Once you wipe and reload your system you should really use a firewall stronger.  It should also have IDS (Intrusion Detection System) and if all goes well and evidence system log.

    You say that: "as Comodo firewall still work" I would rethink.  If it worked you would not have been infringed.

  • Some links in IE8 on Vista does not open

    Hi all

    I am running Vista, IE8, updated with patches and other.  I have installed Firefox with Firefox and Google Chrome as default browser.  Since I built the PC, several hyperlinks (as on dealcatcher, for example) does not open properly.  When you click on it, they will open a new tab, but I get an error message that says: "Internet Explorer cannot display webpage".
    I searched for a few days and tried the following hotfixes:
    Re-registration of the dll through the command run (there are about 6, and half of them gives me an error when I try to run)
    Making IE8 default browser (after that, the stupid thing will not open dealcatcher.com at all, although most of the other sites still work)
    I don't have a problem with hyperlinks from Outlook, because I do not use it.  In fact, none of the Microsoft e-mail programs are installed at all.  I use Thunderbird for my email client.

    Any ideas?
    Thank you
    Ryan

On the other hand, the Media Player for Internet Explorer plugin works very well. Please notify. On the other hand, the Media Player for Internet Explorer plugin works very well.

  • NVIDIA Control Panel does not open

    I just reinstalled Windows 7 on my PC and the NVIDIA Control Panel does not open when I click on the link in the windows control panel.  I installed it by using Windows Update.

    Should I remove it and reinstall again?

    Hi AdelaideJohn67,
     
    I suggest to uninstall existing NVIDIA Control Panel and restart the computer. Visit the NVIDIA Web site, download and install the drivers manually.

    After installing the drivers, restart the computer and just do a right click on your desktop and watch if the NVIDIA Control Panel whether or not written.
