DAQmx statements without DAQmx drivers loading on target PC cause fatal

I have a class with DAQmx statements.  If the application is installed on a system without Measurement & Automation (MAX) and support for the installed dryers, just instantiate my class causes my application to plant.

How to catch the error or check if DAQmx will work before my class instantiation?

Some examples of statements:

Counter0BufReadTask private as task = Nothing

Counter0BufRunningTask private as task = Nothing

Private counter0BufReader As CounterReader = Nothing

Private counter0BufCallBack As AsyncCallback = Nothing

Private counter0BufAr As IAsyncResult = Nothing

Hi fjm1,

One thing you could do is to include the runtime configuration OR-DAQmx with your Installer.  It is a reduced version of DAQmx and keep your application from crashing. Your final statement is the other option.

  • 2010 DAQmx drivers remove 8.2 drivers

    I recently installed Labview 2010 and I just noticed that I have more DAQmx drivers to 8.2. I need support legacy applications in my environment of 8.2. I just need to reinstall the older DAQmx drivers? Experience tells me that it will hang by the most recent drivers.

    Hi Brian,.

    I am pleased to bring you this to - it seems that there are two potential product advice must be here:

    1. ADE DAQmx support for older versions of LabVIEW

    2. the ability to have multiple versions installed simultaneously DAQmx

    Nature of being both a hardware driver DAQmx API, #2 is probably a bit impractical.  I see #1 as a starting point for the discussion.  If you had the opportunity to update the kernel and API components for a compatibile with the latest LabVIEW version, but at the same time to keep the support of the API for older versions of LV not officially supported by the last DAQmx?

    I do not understand the situation you are facing, and I wish there was an easy solution.  For your whole particular of ADEs (LV LV 2010 8.2), you should be able to use DAQmx 9.1.5, but once LV 2011 spell (for example) you will have the same problem again.

    I encourage you to take the time to post a (or both) of the two suggestions above for the Exchange of ideas that I would be interested to continue any discussion.

    Good thing NOR is followed pages they have where they display this information in the case, he would get real confusion.

    Speaking of confusing information, the two seemingly identical KnowledgeBase article a wrong shows that DAQmx 8.9 supports LV 2009 (8.9.5 was in fact the first version compatible with LV 2009).  Information will soon be corrected and the KBs will be grouped in one article.  I guess it never does hurt to check the readme file for this type of information for a particular version of DAQmx you are interested to be on the safe side.

  • where the daqmx on real-time target files are stored?

    Hello

    I'm working on an application that is embedded in a desktop RT target.  To make the system easier to maintain in the future, I would like to be able to generate a DAQmx task programmatically to the *.ini file exported from MAX.  In this way, users don't know what my code does to recalibrate the sensors or manage new material; they only know how to use MAX and where to store the files in config on the target.

    Where are the task daqmx, channel, and scale information stored on an RT target?  I have been through the files on the target you are looking for something that contains my task data but have found nothing, while dropping a node of system property in a VI running on the target will give a correct list of the tasks that I set up.  (The project that contains the aforementioned VI has no tasks in it IE: I do not import into the project.)

    Is there a utility that runs on the RT target that can generate a task at the time of the *.ini files exported?

    Thank you

    Exahustive keyword search led me to an answer on the forums.  I'll post here a brief summary in case someone else uses the same key words I.

    1 export the MAX configuration file

    2. write a VI that uses tools in the system palette to load the configuration on the target in real time.

    3 profit.

    In my case, the VI I wrote to download the config DAQmx also generates the configuration files for the screw on the side host and target, so everyone knows what is called tasks.

  • Is there a way to store the State of the vi loaded dynamically without resorting to tricks Subvi?

    I have a VI to open a UDP connection, data recovery, and then close the connection:

    Set the State to 1 opens a UDP connection.

    Definition of State 2 retrieves a UDP packet. Most of the boxes above is for the manipulation of data.

    Placed at 3 farm the UDP connection.

    Now, calling this vi as a sub - VI works fine:

    But calling the vi dynamically only:

    The second call inside the while loop will raise an error. Apparently, bibliographic are not valid from one call to the other when you call a vi loaded dynamically. What I need to know is, is there a convenient way to get around this?

    Hello

    The call dynamically a VI within a while loop can be pretty bad in terms of performance and I'm not sure it's a good idea.

    But if you really want to do this, using the function "Call by reference node" would be more appropriate in your case (you can find some examples easily).

  • Having problems with maintaining device drivers loaded on Windows 7 audit mode

    Trouble in paradise. I'm working on new images of Windows 7 and we're having problems that new pilots appear after the computer has been deployed. I extend to the computer in audit mode and either use an answer file to add drivers or add them manually using pnputil. I add drivers for 5 different Dell Optiplex computers. When you use the answer file the computer back mode audit on this computer, and drivers have been installed. After checking the Device Manager, everything is in place. I also checked the Driverstore folder to make sure they have been installed, they. But when I finished the process sysprep, the image on your computer and place it on another computer, it does not see the new drivers. I still have to add them manually. I did it on five computers with the same result so I know that the pilots were initially loaded correctly. For some reason any after sysprep, it seems to lose track of the path to the drivers when the computer starts in windows setup mode. Once installation is complete, the same missing drivers in Device Manager are still missing. Even if they were there to audit mode. If I send the device missing in Device Manager the driverstore in research, he finds the driver without problem. Here's what I use for sysprep:

    C:\Windows\System32\Sysprep\sysprep /audit /reboot /unattend:C:\Windows\System32\Sysprep\imagetest.xml

    And then run the oobe and generalize the windows sysprep interface options to stop out of audit mode

    I hope that I do just something wrong, it's simple.

  • Load control target

    Hello

    Target load if you place your order is not used (because we do not have the etl for business license), what happens if I load A table data in table B, then the same operator table B in table C?

    Can I be sure that table B is always loaded first?

    Kind regards
    Carsten.

    If you create a queue table a-> B-> table C table, you can be sure that B is completed before the data are transferred to C, even if you are not Enterprise ETL.

    If you create a mapping table A-> table B and table A-> table C then it is not so easy to identify, which table is filled first table A or table C. as far as I know, OWB uses the sequence in which the operators table where slipped into mapping as a default load order. "Random" approach cannot be used, like PL/SQL doesn't support any random execution in a package...

  • Add more than 2 lines for a select statement without inserting rows in the base table

    Hi all

    I have a below a simple select statement that is querying a table.

    Select * from STUDY_SCHED_INTERVAL_TEMP
    where STUDY_KEY = 1063;

    but here's the situation. As you can see its return 7 ranks. But I must add
    2 rows more... with everything else, default or what exist... except the adding more than 2 lines.
    I can't insert in the base table. I want my results to end incrementing by 2 days in
    measurement_date_Taken on 01-APR-09... so big measurement_date_taken expected to
    end at study_end_Date...



    IS IT STILL POSSIBLE WITHOUT INSERT ROWS IN THE TABLE AND PLAYIHY ALL AROUND WITH
    THE SELECT STATEMENT?

    I used the "simplified" version, but the principle should work for your table, S2K.
    As Frank has already pointed out (and I fell on it while clunging): simply select your already existing lines and union them with the 'missing documents', you calculate the number of days that you are "missing" based on the study_end_date:
