Simultaneous access from two virtual mashines on one framegrabber

Hello,
is it possiblie to get access from two virtual mashines on one framegrabber. I want only get the information from Cam-A  and transfer it to virtual mashine A. For Cam B and virtual mashine B is it similar.
My problem is that I have to measurements but they have to run at they same time and I want to use the Vision Builder AI for this. If it's right that that  the Vision Builder is able to do only one measurement at the same time.
Another solution could be, to export the vbai to .vi's and import it to LabVIEW, coundn't be?
best regards
phil
 

As far as I know, virtual machines cannot access plugin frame grabbers. Are you using GigE cameras (which should work in VMs since they can use GigE ports of PC), or CameraLink cameras (which shouldn't work in VMs since they require plugin frame grabbers)? As far as processing images from two different cameras at the same time in VBAI, You can process images that were acquired at the same time in VBAI, but the processing steps don't execute simultaneously. Do you just need the acquisition to be in parallel or the processing as well. Why does the processing need to happen in parallel (is it for timing/perfromance)? If the inspection is running on windows, you can have two instances of VBAI running at the same time and each instance can process a different camera, but it may be more challenging to coordinate the results of the two different inspections if they need to be combined at some point. If you are acquiring on Windows, you could also use the API in LabVIEW to control the two inspections that are happening in parallel and coordinate the results. See the example of how to use the API here:

Hope that helps,

  • Simulating two virtual monitors on one physical monitor

    Is there a application or system extension to allow simulating two virtual monitors on one physical graphic card output?
    The origin of the problem comes from the wish to drive two external displays from a macbook pro. (without USB driver!!)
    The only solution is to use Matrox Interfaces that tell the system that one big screen is pluged to the grafic card. So the Graphic card puts out a signal for a big widescreen dispaly. The Matrox splitt it up the two physical monitors.
    The problem is that dual screen applications like Aperture or apples color don`t work with floating windows and no window snapping works good etc.
    So a system extension or thired party application must split the one big display coming from the matrox in two virtual displays that are like the original two.
    It is a shame that apple don`t provide this functionality (two external monitors) on their high end laptops. They may loose their attention on the pro user and keep on focus on the dummy Iuser. Unfortunately this means a reduction of quality in their high end products.
    Thanks for answering that wired question!

    The only thing akin to what you want in OS X is Spaces (System Preferences) which can be used to set up virtual screens. I don't know if it's what you are looking for. I'm not aware of any such third-party utility although you can search for one at VersionTracker or MacUpdate.
    I suppose there may also be a commercial product around, but I don't know of one. Matrox makes a hardware add-on for having multiple monitors on a laptop, but I don't know if they have a utility such as you have described. You may find something doing a Google search.

  • I am wanting to exactly match two ID numbers from two differing worksheets within one work book. Once matched I am wanting to retrieve a row value from the second worksheet into the first. Any help much appreciated.

    I am wanting to exactly match two ID numbers from two worksheets within the one work book. ID numbers are non linear. Once exactly matched I wish to retrieve a corresponding row value from worksheet two and have it appear in worksheet one against the correct ID number. I have been looking at IF, VLOOKUP, and MATCH functions and suspect that what I want to do requires a combination of two or more. Any help will be greatly appreciated.
    regards Vaughanh

    Vaughan,
    Data A:D is all cells start at column A thru column D.
    There is built-in help using the menu item "View > Show Function Browser"  in the search field (top right) you can enter vlookup and you will see the detailed description.
    From this we see:
    VLOOKUP
    (search-for, columns-range, return-column, close-match)
    search-for:  The value to find. search-value can contain any value type.
    columns-range:  A range of cells. range is a reference to a single range of cells, which may contain values of any type.
    return-column:  A number that specifies the relative column number of the cell from which to return the value. return-column is a number value. The leftmost column in the range is column 1.
    close-match:  An optional value that determines whether an exact match is required.
    close match (TRUE, 1, or omitted):  If there’s no exact match, select the column with the largest top-row value that is less than the search value. Wildcards can’t be used in search-for.
    exact match (FALSE or 0):  If there’s no exact match, return an error. Wildcards can be used in search-for.
    So... the 2,0 means return the value form the same row as the lookup value but from the 2nd column of the range.  3, 0 means from the 3rd column.  the ", 0" means exact match

  • ICloud Mail - Accessed from two locations simoutaneously?

    Hello,
    I got this message this morning from my iCloud Mail.  It says that my iCloud Mail account has been accessed from two locations simoutaneously, and that I have 24 hours to receive confirmation of ownership of my account or it will be suspended.  There are no links in the email to confirm that I am the real user.  What do I have to do to prove that I am the real owner?  I don't want my email suspended!
    Thanks for any information before 9:00 AM tomorrow, because that's when the 24 hours are up.

    Yea, that sounds fishy.  Can't believe that Apple would mispell iCloud.  Looks like someone wanted you to reply with your username, password and location.  Might be worth contacting Apple about it.  If you explained that you were contacting them as a good samaritan to report a possible security threat that might effect other users they probably wouldn't charge you for the call.
    If you're concerned, you could always change your password (http://support.apple.com/kb/HE36).  After doing so you would need to sign out, then back in using the new password for all services you are using the ID for.  For iCloud, you have to delete the account (which only deletes the account and your synced data from your device, not from iCloud), then sign back in with the new password.  Your data will be synced back when you sign back in.

  • I sent some emails from one of my email accounts and now it shows that these emails have been simultaneously sent from two of my email accounts

    I sent a few emails from one of my accounts that are set up in my Thunderbird. Now I see that they have been sent from two of my accounts, simultaneously. It shows them in both Sent folders and with the respective email address as sender.
    Those email accounts have been set up in my Thunderbird for a long time now and have been working correctly until now.
    How can I prevent this from happening again? I don't want to send people messages from two different emails at the same time.
    I'd appreciate any help on this.
    Thanks,

    In my case, TB is sending a copy of all my sent mail to the account that is associated with the smtp server. I have four accounts that I check via TB and the sent mail is being kept in the original folder and also in the sent folder of the account to which the smtp server is connected. If I change the smtp server from one gmail account to another, the sent mail follows. I then have two copies of the sent email, one in the original folder and one in the smtp server account's sent folder. I only want the one in the original folder. How do I stop the sent email from also being saved in the smtp account sent folder?

  • How do I merge my itunes folders from two user accounts on one computer?

    I've made purchases from audible.com and on itunes from two different user accounts on my home computer.  When I try to sync my itouch with my library I am missing the purchases I made from the other user account.  How can I merge these together so i can have everything at once that I have purchased?

    Copy or move the song files from one account to a shared location and then drag them into the open iTunes window when logged into the other account.

  • How to do a simultaneous snap from two GigE cameras?

    I have 2 Basler Scout 780-54gm cameras (monochrome GigE) that I am triggering externally at 10 Hz. This frame rate is modest and the resulting data rate is not particularly high. I would like to get images from both cameras from the same trigger pulse. I have an Intel Pro/1000 NIC and I am using the NI driver that shows up as National Instruments GigE Vision Adapter. When I use the Basler Pylon Viewer (the software that comes with the cameras) I can see perfect images from both cameras at the same time at 10 Hz. This tells me that the network, NIC and drivers can handle the data rate with no problem. I have jumbo frames enabled.
      When I try to acquire images into LabVIEW 8.6 with IMAQdx vis, though, I run into problems. I can acquire from each camera alone, but I can't get both at the same time cleanly. The images are shot through with black horizontal lines that appear and move erratically. I have attached a vi that shows the problem. I configure and start both acquisitions, then enter a while loop which reads the images. If I do the acquisitions sequentially by starting and stopping them inside the loop and making sure that one stops before the other starts then I get high-quality images but they are not from the same trigger pulses, and the overhead of starting and stopping the acuisitions slows things down so that I can't get images from every trigger.
      My guess is that this is a problem with the way LabVIEW is managing memory, resulting in corruption with simultaneous acquisitions. Are there any settings I can change to cure this problem? I have experimented with everything that I know about, but no success yet.

    Hi Richard:
    You should put the tick count function in a sequence structure in order to make the loop timing consistent each iteration, but what are you receiving as a loop time?  If it's operating in less than 100ms, it shouldn't be the software that's affecting the images.
    One other thing you can try is to get rid of the error wire between your Get Image VIs.  This will keep the program from forcing a delay by executing the functions one at a time.

  • Loading data from two flat files into one table

    Hi All,
    I want to load few fields from one file and few fields from another file and load the data into one table in the database.
    For Ex: I have two flat files file1.csv and file2.csv and file1.csv containes 25 columns and file2.csv containes 12 columns, i want to load 20 columns from file1.csv and 7 columns from file2.csv into the table
    how to combine the columns from both the files and load them into one table at a time?
    Any help is appriciated
    Thanks

    Use external tables.
    If using Oracle9 or higher connect both your csv with database as separate external tables and load the requited fields in new/requited table.

  • How can I combine two databases, from two computers, to have one combined database of messages?

    My old XP computer recently died and I had to build a new Windows 8.1 machine. While I was down I used a laptop as a temporary replacement. Now my new machine is running fine and receiving e-mail, but I now have two databases--one on the new machine and one on the laptop. Both are based on a recent backup, so they are lengthy--except that the new machine's database has a hole in it for the period I was on the laptop and the laptop's database also has gaps. How can I combine two databases into one that includes the messages from both machines?
    Thanks in advance,

    Thanks for your reply. My profile folder did not contain any MBOX files. I found them in another folder on another drive. The Import-Export tools simply transferred each folder to the current one as a sub-folder. Then I had to use ctrl-a to select everything in the folder and move them manually to the current folder (such as inbox). Then I could use the other utility you mentioned to remove the duplicates. This had to be done, one folder at a time, to combine each folder. It worked, but I had about thirty-five folders to deal with. The whole process took most of two days to complete. I wish there was a simple way to blend everything together in one action, but I could not find an add-on that would do this.

  • Transfer data from two oracle version to one sql server 2005

    Hi,
    I have two database servers on different machines. They are
    1) Oracle 8.1.7.4
    2) Oracle 7.3.1.4
    I have to create agents which can transfer tables from these two databases to one machine having sql server 2005 database.
    Please tell me what are the options. What drivers i need to install on machine having sql server 2005 so that i can transfer data from both oracle versions.
    Thanks
    Rajneesh.

    Your Oracle databases are so old you might want to look around and see if you can find dinosaur bones near by.
    Given the differences in data types between Oracle and SQL Server I'd suggest you start off by dumping the data into delimited ASCII files and then loading it using whichever SQL Server tool you wish.

  • How to switch from two-levels tabs to one.

    HTML DB v2.0.
    I noticed that having two levels tabs I am getting error (can not fetch the record) because the "Clear Cache" option is available only for Parent Level tab.
    My page is designed like this: Person's info, report on children records, and a form to enter/edit children records.
    I'd like to switch to one-level Tabs and "Clear Cache" every time you go from one tab to another so form will be in a mode to enter a new record.
    I tired to change the theme to one-level tabs, but nothing really changed when I went to create Tabs - it's asking for a Parent tab.

    Hi zavadskaya
    Try:
    - keeping the two level tabs.
    - add a process to the Page Rendering area of your page
    - the process is set up as:
    - Type = Clear Cache for all Items on Pages ..... enter your page number.
    - Process Point = On Load - Before Header
    I hope this helps.

  • Can you put apps from two iTunes accounts on one device?

    I just got an iPhone from work. I would like to put some apps I got for my personal iPod on it, but I also plan to purchase some work-related apps using a work-account (charged to the company card). Is this possible? From what I understand it would be possible to put apps I purchased for the iPod onto the iPhone, but I can't find if I can then use a new account to purchase more apps for the iPhone.
    Can someone let me know if this would work? Otherwise I'll just buy the apps using my personal account and get reimbursed (not as neat, but I can't use the work account for personal apps!)

    Yes, you can do that.
    You just have to remember from which accounts you bought which Apps when updating them, as you won't be able to update an App bought in one iTunes Account from another iTunes Account.
    As far as purchasing new Apps goes - just log-in to the required iTunes Account on the computer you sync your phone to (which should only be one computer), purchase the Apps then sync them to the phone. If you want to purchase Apps from the other iTunes Account, log-out in iTunes then log in with the other iTunes account.
    It might just be easier to purchase everything through the one personal account though...

  • What is the best way to have access from two separate computers on a network to a large group of data files and be able to modify the dat from each system?

    Have three systems: MacBook Air, iMac 27, running current software and an older iMac 24 running earlier version of OS-X.  All connected using Airport through a Linksys router.  Have a large number of folders (2800 equal to 1.5 TB) and need to be able to update from both MB Air and the 27 as well as have some sort of at least weekly backup.  What is the best approach to accomplishing this? This is a small home network used to store audio books for the blind.

    I would recommend a proper NAS.. Synology or QNAP are top brands.
    OR, getting another lightweight computer as a server. eg newest Mac Mini or second hand one with large storage, USB3 or thunderbolt.
    Apple routers could be pressed into service but are not designed for this task.. they will be slow, and without ability to backup.

  • How to change from two sided printing to one page printing on a macbook air

    How do you change the printer setting on a macbook air? I go to print something and it prints double sided, is there a way to change that setting?I have an Epson printer that does air printing. Please help!

    That would be a function of the printer settings. So once you call up the printer to print something go into the settings and change it from Duplex to single sided printing.
