Programmatic read access to project symbols

Hi,
I'm wondering if there's a way to achieve programmatic way to achieve a read access to the symbols defined within a project apart from the conditional disable structure? I have tried access via VI server, but haven't succeeded  
I'm (still ) using 8.20.
For me, it would be a nice way of passing certain enviroment settings....
Thanks a lot!

Programming languages don't create bad code, programmers create bad code....

I know this is an old thread, but I'm betting that more people will want to know how to do this, and it's not all that intuitive.  I wrote a VI that gets symbols for the project itself, or for a target within the project, including "My Computer."  I haven't written a VI to set symbols yet, but it's the same idea except that you'd use the "Set Tag" method instead of "Get Tag."
This one is in LabVIEW 8.6.1, just because that's what I'm using today.  (Sorry, no LabVIEW 2009 snippet)

    Unfortunately there is no other way to access the symbols via VI server. It is not possible to edit these symbols at runtime in general, which would not make sense, because these symbols are ment to give the user the opportunity to do conditional compiling, and so the state of these symbols needs to be set BEFORE the VI is compiled/started.
    You could accress the value of these symbols, by reading the .lvproj File directly. The .lvproj files are XML-Files, and there is a item called
    <Property Name="CCSymbols" Type="Str"> .XXX.</Property>  in the XML File. The XXX stands for the name and value of a symbol.
    You could use File I/O functions to access these values.
    Hope this helps!

  • Programmatic read access to applet console trace level

    Is there any apis for getting the current trace level setting of the applet java console?

    thanks for the info.
    But as a user I would find it confusing, especially as that would mean to see traces from your applet I would have to turn on, and see, traces from the JVM mixed in with them.I'm surprised others don't use System.out.println, or e.printStackTrace in their applet code. Is that not common? It irritates me to know end that i'm not allowed (by the company) to have them there. So a problem occurs at a customer site, and there's no way to know what happened. So i was able to talk them into emitting important stuff as long as the user consciously set the trace level up, something a normal person would never do, most likely.
    So how do other people log information from applets? I can't imagine you're actually logging errors to the filesystem? sending them back to the server? seems hard to believe anyone would do that?

  • Is it possible to programmatically change the value of a LV8.2 project symbol at runtime?

    I need to programmatically change what a conditional disable structure will execute at runtime. (See this thread for more details if you're interested.)  As far as I can tell the only way to do this is to change the value of a project symbol at runtime.
    I've tried to find a property that allows me to do this but so far it eludes me.
    Anyone know how to do it?

    This is definetly not possible. When the conditional disable structure is compiled, only the actual case is compiled. The other cases don't even have to have valid code, they can have broken wires or bad VI's in them!
    Like Mike suggested, you need to load VI's that do the task dynamically.

  • Active Directory Changes have causes users to loose access to Projects they are set as contributor too.

    Hello,
    We recently had an employee of our helpdesk delete (by accident) and recreate a number of Active Directory user profiles.  The profiles were created exactly like they were before, but now those users are not able to access the projects in TFS that they
    have contributor permissions too.  Some of these users can see a minimal set of objects in the Source Control Explorer, but each item has a (+) plus sign next to it as if the object does not exist in the repository.  The users and windows groups
    that are concerned are still listed inside of TFS's group memberships for each project.  I have confirmed that the sync from AD with TFSJobAgent.exe is completing with out errors as well.
    Is this a SID issue where TFS actually thinks that these are new users, and if so how can I best fix it for those users?
    Doug Dayley

    Hi Doug, 
    Thanks for your reply.
    Ok, let’s check whether TFS Server can identify this user and its groups which this user belonged to. Please execute below command for this one user, then view command result, check if the user name and SID both show correctly in result, and whether this
    user belonged to groups all listed in command result.
    Tfssecurity /imx “domain\username” /collection:URL
    If this user’s all information show correctly in command result. Please try to remove this user from your TFS server, then clean the TFS Cache, re-add this user back to TFS Server, then check if this user can access your team project as expect.
    Clean the Cache for TFS 2013 manually(delete the content of the folder only, not the cache folder itself):
    Clean the Cache folder on Server machine. The folder path is:
    C:\Program Files\Microsoft Team Foundation Server 12.0\Application Tier\Web Services\_tfs_data.  
    After cleaned, on Server machine, click Start and select
    Run… to open the dialog box, then input iisreset.exe and click OK, wait it run completely.

  • Composition of business team in GRC Access control project

    Hi
    Can I get any information about the composition of business team in a GRC access control project?
    What type of people form this team?
    Please provide some clarity on the role of business people in this type of projects.
    Regards
    Abhijeet

    Hi,
    Idealy the team should comprise of
    1] A representative of the IT Governance team -he ensures that the IT delivers value to the business,the risks have been analysed and fully addressed to.
    2] The Buiness process owners -these people only define the access restrictions for various activities like purchase,payment,etc.
    3] Application specialist -in charge of SOD-he defines the roles and profiles for the access control.
    4] If required a member from "Assurance" - these will be auditing the "access control " on a regular basis after the implementation.
    5] The configuration team.-they configure the controls in the Appln.sysytem

  • I updated to yosemite os and was in the middle of a project with final cut pro 10.  Now it says final cut pro is incompatible.  How can I access my project and/or update final cut?

    I updated to yosemite os and was in the middle of a project with final cut pro 10.  Now it says final cut pro is incompatible.  How can I access my project and/or update final cut?

    There is this offer of a trial version FC Pro X with 30 day runtime:
    http://www.apple.com/final-cut-pro/trial/
    Too bad you didn't have a complete backup that could run the previous OS X
    and then you could resume using an earlier Final Cut Pro (10) or (7) since a
    clone would have been a means toward that position.
    http://www.apple.com/support/finalcutpro/
    http://www.apple.com/support/pro-apps/
    This appears to be another good reason to check out all the reasons why one
    would want or need to upgrade a working OS X version, since these kinds of
    events are known to happen as a direct result.
    Sorry to not have an answer to this, other than try & use the Trial version...
    Or see if someone at Apple sales/support can field your issue w/ an answer.
    Good luck & happy computing!

    Can't find last import from iPhone!
    Noticed as I imported I had that view where there was only one project symbol, not all my projects showing by date, but even so pictures were imported. It took the time to do them, so where aare they? I have closed and restarted to get back fll view of all dated projects, but nothing can be found from today...

    have i posted it right...??  no response from apple guys...

  • Accessing one project in Premiere CC with two separate macs

    Can I capture a mini DV tape in Premiere Pro on one mac, save the project to an external drive and then access that project from another mac and edit

    Yes.  (As long as you also save the newly captured media, and not just the project.)

  • My Ipad connects with my hotel wifi, but does not indicate that it is a secure wifi, even though it requires a password to access - no lock symbol, hence no password request, hence no internet access - help.

    My IPad connects with my hotel wifi, but does not indicate that it is a secure wifi, even though it requires a password to access - no lock symbol appears against the wifi network, hence no password request, hence no internet access - help. My collegue who also has an Ipad can access the same wifi with ease, so it must be something to do with the settings on my machine, although checking the two machines, there appears to be no difference in the settings.

    My experience with hotel wifi is that it's an open, and unsecured, connection, but unless you agree to their terms on a launch page, you can't go any further or connect. Sometimes I need to force safari to come up and even make it go to a page, to trigger the auto load of the 'agree to our terms' page.
    Unless your machine is work provided so maybe could be blocked from unsecured net access?

  • I can't load 1 Imovie project. Imovie shows 5 projects but only 4 icons show of those. 1 projects symbol won't come up so I can't click on it to work on or play. Please help me as there's lots of work on this project I don't want to lose.

    The performance fixes is a biggy for me, though the other missing
    stuff I use makes me have to use both versions for various things:
    "but they seem to be committed to another release/version."
    Well ... now that's the rub. I would actually welcome this intermediate version to play with (even with the cost of upgrading) if I could rely on it to be finalized into 6.0, full featured, without it taking as long as it has to Upgrade from AA3.0. I would say it was a VERY smart move to give us a preview of 6.0, if I felt in, say, six months they would provide us the fully functional update. But, HOW many years has it been. I felt screwed over while they played around with Sound Booth.
    I was with you for a minute in most of what you said, until your credibility went down a couple notches with me on the statement trivializing midi functionality. I though that was a very clueless statement:
    "but I have no need for a midi controller and if I want a drummer to keep perfect time I'll get a drum machine."
    It does make some of your other statements suspect, tho I won't take it as far as therealdobro's "what's your stake" question.

  • Shared Services, create read access to a cube into an application us a grou

    Hi,
    I have an application with 3 cubes. I have created a group in Shared Services, and i want to give read access only to one cube.
    If i give provision to this group , i only can give read to all the application, so all the cubes are going to have read access.
    How must i do to give only read access to one cube and not to all,
    Thnx
    Guillermo

    Hi,
    This post will help answer your question :- Assigning database access using Shared Services
    If you are using Shared Services access is applied at application level and you can't select individual access to each database.

  • How to programmatically read/write the range of a fieldpoint AI channel using LV

    Is there a way to programmatically read/write the range of a fieldpoint AI channel using LV ? The example on NI site only permit you to have the name of the device and channels, not the actual set of the range of measure. Anybody has a VI (LV5.1 please)to share?
    Thank you very much

    If you are using the FieldPoint VI's (Open, Create Tag, Read, Write, Advise), you do not have the ability to change the range of a channel. If you have a FP-1000 or FP-1001, you can use the Optomux commands as described in the FP-1000/1001 Programmers Reference Manual (FieldPoint Optomux VI's are available at ftp://ftp.ni.com/support/fieldpoint/LVFPOpto/ ).
    Alternatively, if you have an ethernet network module and LabVIEW 6i or later, you can use the ethernet configuration VI's that ship with FieldPoint Explorer 3.0.1.

  • How to fix: Unhandled page fault on read access to 0x00000000 at address 0x00aa4088 .

    hi
    i recently downloaded a game (assassins creed I), i opened it and the intro showed up after that the screen went white, then black and a window came up calld exception raised and then below it, it said, Unhandled page fault on read access to 0x00000000 at address 0x00aa4088.
    i have tried opening it many times and the same results come up.
    i've looked everywere and found that other people have had this same problem but no one has fixed it yet
    any help will be appreciated
    thanks

    I did try the OP's solution, but it proved to be only temporary. Take a gander at my proposition, and if you are experiencing many issues with your MBA and WiFi Connection, try doing all of the possible fixes located on these forums to see which one (hopefully) works for you. Here's my attempt at a solution.
    Well, after toying around with many of the settings on the MBA, I then began to work on the AirPort Extreme (Gigabit Version) and I discovered that the MBA would only connect when I selected "Interference Robustness" when configuring the MBA. This made a difference no matter what "Wireless Mode" the AE was in, be it 802.11n(b/g) Support, plain 802.11n(5Ghz), ect. So, try that out if you have an AirPort Extreme/Express and MBA, and post your results. The MBA is running 10.5.5 with only one update remaining (10.5.6).
    {This has posted in various threads by me, myself, and I, and I am only reposting so that many threads are aware of this. Hope it helps at least one person.}

  • How to find from the data dict if a user has read access on a directory

    How to find "dynamically" if a user has READ access to a directory object.
    I want to know if there is a data dictionary table that holds if a user/schema has read access to a directory object.
    I know there is an dba_directories table and an all_directories table but they dont give information as to which user has read access granted to the directory.

    Not so difficult.
