Control reference 1055 error when you use a loop for

Hello

I'm having a problem using control references to accomplish the following: I a VI that reads data from a text file, and then uses that automatically update the value of a control on front panel on two live different, then set the default values, and then save them. Comes from the array of control references, I tried looping on text labels until I have find the one corresponding to the order, I want to change and then update its value. The problem I have is that if I use a loop for, then 9times of LabVIEW 10 complains error 1055: "LabVIEW: object reference is not valid. If instead I the wiring to the index table and manually extract the reference, then it works every time and for each index of the reference of the order.

Can someone take a look at my code and just see if its obvious what the problem is? In this case, I have a simple solution, but I would really like to understand what I did wrong. I have included as a code snippet, but also attached the files if that helps (Its Import_Colormap.vi, which is the problem). Persons with disabilities code fails, the active code works but I can't see what is really the difference between them - I can change the index of array 0,1,2, 3. and no mistake.

Thank you.

Your "Colormap.ctl" is a strict type def that contains a ring.  You define the elements programmatically, make the default values, and then save the "Colormap.ctl"?   I was never practicing this but here is a thread that covers this in detail. I do not understand what you expect reach by running.
The next thing: at the same time (at the same time!), you open the Colormap.vi (this is what we see in yout PNG) that contains an instance of the Colormap.ctl on the front panel. I'm not pretty sure if LabVIEW can handle this correctly. This could be the reason why you sometimes get the error 1105.
I prefer StringsAndValues and eventually the value of the ring running.  There is no need to do it with a def of strict type.

  • IMAQ Grab Acquire.vi error when you use an external trigger on a card NI PCIe-1433 (sync problem?)

    According to my recent post on getting up and running with the NI PCIe-1433 camera link card, I ran into a bit of a snag.

    When you use the internal trigger on the camera, everything works 100%. I can view all the data from the camera in MAX as well as in the labview project. However, whenever I have set the mode switch is where things start to fall apart.

    What I have confirmed:

    -Camera is switching between inside and outside triggering.

    -NI PCIe-1433 camera link card is set up properly. While in external mode, I can trigger the camera by using a function generator and check the wire to the MAX. Everything works fine.

    When the unit is in external mode, the function Acquire.vi enter IMAQ - my mistake VI. The error is:

    Code :-1074397150

    The possible reasons for a timeout.

    Now, I have it set up so that a mistake here will not end the LabVIEW file. Sometimes, data of interest makes however (about every 10 seconds-ish). So what seems to be the case, it's that this external trigger signal is not in the lineup when the clamp is attempted. Is it possible to synchronize these? May reference the trigger signal external sort in my LabVIEW project so that the clamp is performed only when that trigger impulses?

    So I solved my problem. He was in time. The external trigger that I used for the device was simply too slow. I was initially using a trigger from 2 Hz to be able to view the values changing on LabVIEW probes. But it was enough to get enough data to move above the camera cable to assemble a picture and kept it in time. Travel up to 9 kHz solved the problem. No adjustment to the camera settings or LabVIEW code was necessary.

    Hi the string 1,

    Make sure that a certain folder path is in the PATH environment variable. Follow these steps:

    (a) first, to determine the correct path to add to the PATH environment variable.  Look in C:\Windows\twain_32 and there should be another folder (example:-CNQ4803). This is the way that is needed to be added to the PATH environment variable. C:\Windows\twain_32\CNQ4803

    (b) alter the PATH environment variable. Go to Control Panel, Systemand then choose Advanced system settings in the left column.

    (c) this will bring up the System Properties dialog box (it should already be in the Advanced tab).

    Hi Aaron,

    At first glance, it looks like there may be a string of property that is not a string data type. However, before you dig too deep, try to reload the version to see if that makes a difference. I had a similar problem before and it is solved.

  • How to disable direct sound when you use a plugin for guitar?

    I use the Waves GTR plugin for recording guitar in Logic Pro X, but because it puts a lot of pressure on the CPU, I tried he governs through a "bus" instead of having the plugin separately on every guitar track. The difference is that when I use the bus option, I can't seem to get rid of dry direct sound which is obviously very embarrassing. The only way for me to get rid of the direct sound is to use the RTM plugin on every guitar track that quickly causes the overload program when using several of these titles.

    Anyone know how to get rid of the direct sound when you use the alternative of bus for the guitar tracks?

    just at the exit of the guitar channel strip no output. This way you won't hear at the follow (because the dry track will not be transmitted to any output)

    Srikkanth,

    For this you need to calculate the max outside of the update statement and then use this value in the update statement.

    The bartime is a control in the block?

    If Yes, then you need to find the max manually, and if it isn't, then you can write a sub query to find the maximum value.

    Kind regards

  • Error Msg: "there was a problem sending the command to the program" when you use a shortcut for FireFox

    This only happens when I use a shortcut to call Firefox. I am running Windows 7 Professional. The Firefox window opens after the error message occurs, so I would class this as a gene.
    Many help comments mention 'ddeexec' removal of Firefox registry entries. It worked for a while (it seems to be related to updates of Firefox), but now no longer works: ddeexec is removed, but the error message persists.

    I found a fix for Win 7 (x 64) based on two observations:

    1. the waiting period does not exist if Firefox is already running.

    2. There are (at least) two types of shortcuts: Application and URL. When Firefox is the default browser, shortened URL get a timeout message. A the application shortcut to Firefox works without any problem.

    Follow these three steps to create a new shortcut that runs Firefox with the URL as a command:

    1. create a shortcut to the Application either by copying an existing shortcut, or right-click on the desktop, select new | Contextual and choose the location of Firefox.exe.

    2. then right click to open the new shortcut, properties. On the shortcut tab, you will find:

    Target: "C:\Program Files (x 86) \Mozilla Firefox\Firefox.exe.

    Start in: "C:\Program Files (x 86) \Mozilla Firefox".

    3. copy the URL address, type a space after the quotation marks of the target and paste that URL, it should look like this:

    Target: "C:\Program Files (x 86) \Mozilla ' http://postini.com

    I used a short URL to this example to fit on a single line, but the useful commands can be much longer; for example:

    https://login.Postini.com/exec/[email protected]

    The second example opens a connection to Postini spam filter window and between your email for you. Below is a screenshot of a tab popup properties shows in the middle of the target where Firefox ends the line, and the URL starts.

  • "27049 internal error" when you use recovery with Equium A60-692 utility

    TOSHIBA SATELLITE A60 - 692

    I'm trying to fix a friends laptop. The laptop computer wouldnâ? t start, would go to the blue screen just before the came WinXP loading screen then will re-start. I used a USB 2.5 HDD enclosure "to copy important files on my laptop and then formatted the drive of my laptop. I put the HARD drive in the Toshiba and have used the CD of restoration via an advanced option. on exactly 9mins 50sec time on the recovery process, an error message appears (27049 internal error). After that, it goes to a screen of style BACK with a little more information. Essentially by specifying that the error is "cannot read FILE_BITMAP MFT entry.

    I cleaned the CD
    I swapped the CD drive with my laptop
    Quick formatting it formatted, it is full
    Used the basic option where it does itself and it ERRORS with - not enough space on the partition - there is no partition! or if there's empty sound

    What can I do?

    Hello

    I think that the HARD drive is broken, because if you receive an error message with words like "MFT" (meaning MasterFileTable) then you can expect that the HDD has serious problems.
    OK, easy to talk to it s fast without knowing the machine and so on, but I know a similar error and I can give you the advice to probe hard disk errors.
    You can do this with the help of the "ultimate boot cd" which is a very interesting tool when you need information about your computer or you want to just check if everything works well.
