control references; need help

Im having a VI with control, let's say some Boolean control. Since another VI running, I want to be able to adjust the value of this control. How do I do that? I remember something about creating a reference the command and calling

the reference to an another VI.  If I'm wrong, can someone clearly explain what they are for?

Second, is there a way to call a Subvi and display the pabel before in a tab of the VI which I am the appellant?

Thank you!

1. in your control panel before the local VI go the modern-> Refnum-> Refnum of control and place it on your Panel. Then create what refnum control you need (in this case a Boolean value) and drag ' not drop it in the refnum of the front panel. Now, you will have a refnum your Boolean control in your block diagram. You can adjust the value of this control in an another VI (foreign) simply by placing a property node of your control (overseas VI) and the wiring of the reference already created for her. So basically, you pass the reference of the local VI abroad. The adjusted value can also be passed or, if it is static, it can be placed on the foreign VI.

Sorry, I could not not to edit my previous post. Just thought I would elaborate on the first point a bit more.

Please ask is that something is not clear enough.

Jeff Bohrer says:

On the block diagram, select the terminal you want to update right click > Create > Referance.

Do not understand how I managed to forget this one, including the fact that I use this method in most cases

  • Settlement data based on multiple selection ListBox reference need help

    Hello again,

    The question that I have is selecting from a listbox with multiple selection to fill the tables with the selected data. My code is as follows:

    Void loadData_EventClick (ByRef This)

    Dim j

    Dim k

    k = 0

    If ListBox.MultiSelection.Count = 0 Then Exit Sub

    For j = 1 To ListBox.Items.Count

    If ListBox.MultiSelection (j). Count = True Then

    k = k + 1

    End If

    Next

    TextBox.Text = k

    End Sub

    The code works perfectly up to the second if statement. My current channel group list contains 16 channels and with the second if statement guided the textbox output is equal to 16 (i.e. k = 16), which is what I expected. Im just using the k = k + 1 for the test. Eventually will be replaced by operating code specific to what I need to do.

    So the question that I have is to get the code to recognize what values are selected and referring to the index for the selections in a table. Im not sure on how to do it.

    Any help is very appreciated.

    Thank you

    ~ Nathan

    Attached JPEG shows the current user interface and the output of k with the second if statement commented

    Hey Nathan--

    ListBox.MultiSelection () is a function that returns an array of [multiple] selected items in ListBox.

    ListBox.MultiSelection.Count is a property that returns the number of items in the table above.

    Therefore, the logic in your second IF statement that says if ListBox.MultiSelection (j). Count = True really makes no sense because:

    1. The array returned by the multiple selection (using (j) indexing now refers to a single selected item in the list (which has not its own 'Count' property)

    2. If you don't the array index, assuming that you had selected 4 items in your list, your statement would still be actually as said if 4 = True which is not what you get.

    Make sense?

    Here is a modified version of your code that I hope makes it a little more obvious how these elements relate to one another.  Give it a run; of course, 75% of the code is extranneous to you working end to account, so make sure that you subsequently delete what you won't need.

    Sub loadData_EventClick (ByRef This) ' creates the event handler
    Dim j
    If ListBox.MultiSelection.Count = 0 Then Exit Sub
    TextBox.Text = "Total ListBox items:" & ListBox.Items.Count & + "" \n "".
    TextBox.Text = TextBox.Text & "Total selected items:" & ListBox.MultiSelection.Count & + "" \n "".
    TextBox.Text = TextBox.Text & "Selected Items:" & + "\n"
    For j = 1 to ListBox.MultiSelection.Count
    TextBox.Text is TextBox.Text & ListBox.MultiSelection (j). Text & ", index" & ListBox.MultiSelection (j). Index & + "\n"
    Next
    End Sub

  • Using the value in the array to the variable of reference - need help

    Can someone tell me if this is possible in as3?

    I want to loop through an array and use the array value to refer to a variable.

    The installation program:
    (For illustration only. No real script)

    My MCs:
    triangle_mc
    square_mc

    Variables of placement:
    var triangle_mc_x = 160;
    var square_mc_x = 200;

    My table:
    [shape_array] (contains 'triangle_mc' and/or "square_mc")

    What I want to do:

    for each {(var: chaîne d'élément dans shape_array)}
    Item.x = Item + "_x";
    Item.y = 60;
    }

    It should do the same thing as:

    for each {(var: chaîne d'élément dans shape_array)}
    If (point == "triangle_mc") {}
    triangle_mc.x = triangle_mc_x;
    triangle_mc.y = 60;

  • Need help, cannot set references to Photoshop.Application in VBA

    Hello

    I've used CS5 in the past and have had a VBA program works well (running in Access 2010) which went very well, open Photoshop 32-bit and controlled photoshop CS5 normally, allowing me to manipulate photos, read metadata, etc.  (It was my understanding that at least for CS5, programs including VBA script necessary to run the 32-bit version of Photoshop, not the 64-bit version).

    About 6 months ago, I installed CS6 and VBA program continued to work perfectly, as it always opens the 32-bit version. (I had to be sure that I was not running 64-bit Photoshop when I started the VBA program).  CS5 was still installed but not used.

    I just uninstall CS5, leaving CS6 installed.  For some reason, he left the program VBA disturbed in that the references (that you set in the window of the VBA code with tools > References) no longer seem to be valid.  I can't set a new reference to Photoshop.Application, and the program became unusable.  In other words, the "references" list is more typotheque Adobe Photoshop CS6 or Adobe Photoshop CS6 Object Library.  I've traveled to the C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit) \TypeLibrary.tlb file to add this reference manually.  The programs does not yet compile (for example, appRef As New Photoshop.Application Dim causes an error "User Defined Type not defined").  I get the same failure to compile if I search for and install a reference to the 32-bit version, C:\Program Files (x 86) \Adobe\Adobe Photoshop CS6\TypeLibrary.tlb.  In the past, I also had a reference to the 'Adobe Photoshop CS6 Object Library".  I tried manually to C:\Program Files (x 86) \Adobe\Adobe Photoshop CS6\Photoshop.exe or the 64-bit version of Photoshop.exe, but these files are not accepted and I do not otherwise know the location of the file from the object library.

    I so need help from someone who knows how to solve this problem in the transition of CS5 at CS6 to use VBA.

    Thank you

    EGibbon

    There are global keys which crushed with every version of Photoshop. Photoshop.Application gets for example set for each installation of Photoshop. When you have uninstalled CS5 these keys got deleted.

    You can install CS6 again? You don't need to uninstall. Just install again if it will let you.

    I have a script that wil set them, but I don't really like to use it on other machines of people as it messes with the registry and I don't want to make it worse for you.

  • I need help with the control of two .swf in third.

    Hi, thanks for reading!

    I need help with the control of two .swf in third.

    I have a problem when I need to use a .swf in a digital signage solution, but were advised by the Legal Department, it cannot be changed in any way, I can not also have the source file blah blah blah. I pulled the .swfs on their site and I decompiled to see what I was up against.

    The main SWF that I need control is HCIC.swf and the problem is that it starts with a preloader, which, after the loading stops on a framework that requires user input to (button) on a play button, until the film will proceed and replay.

    What I've done so far is to create a SWF container, HCIC_container.swf, which will serve as a target for the HCIC.swf and I would like to send actionscript in the file, I am not allowed to edit.

    I managed to get done with help from someone on another forum. It is my hope that the following script just start HCIC.swf a framework after the preloader and button play and just play through.

    var container: MovieClip = createEmptyMovieClip ("container", getNextHighestDepth());
    var mcLoader:MovieClipLoader = new MovieClipLoader();
    mcLoader.addListener (this);
    mcLoader.loadClip ("MCIC.swf", container);

    function onLoadInit(mc:MovieClip) {}
    mc.gotoAndPlay (14);
    }

    But unfortunately it does not solve my problem. Because there is a media - controller.swf, which is charged by HCIC.swf who has orders, including the play button to start HCIC.swf.

    Here is a link to a .zip with all 3 files .swf file and all 3 .fla files.

    http://www.axiscc.com/temp/HCIC.zip

    What I have to do is to automatically start the HCIC.swf file, bypassing the pre-loader and play button without having to edit it or in the media - controller.swf in any case. Thus, all scripts must be done in HCIC_container.swf.

    I know it is confusing and it is difficult to explain, but if you look at the files it must make sense.

    ActionScripting is far from my point hard, so I'm definitely over my head here.

    Thanks for your help.

  • 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.

  • [SOLVED] I need help for Shared Documents and Documents on my computer XP Home

    I need help with my shared Documents and other folders on my computer. I have an administrator account. My son has a limited access account.

    I clicked on the option 'make my private files and folders '.  His file was renamed to Documents now my shared Documents. It's just my account.

    I tried to undo what I did. I tried everything (I mean everything) has proposed to do online.

    First of all, I logged in Safemode administrator account. I went to the Documents folder, and I've added the Administrators group and click full control.

    Then I restored system a few weeks before. Then, I went to http://computers.douglasthrift.net/winxpfaq/#faq3_shared_documents and did everything.

    None of them worked. I did so much, that I don't remember.

    Then, I found that the registry key for the Shared Documents lacked in the MUi cache. @shell32.dll,-21785. I entered, but after I rebooted a few times, he disappeared. I have to hurt... In addition to this. Now I face a different problem. I don't know it is normal but when I login my account and click on

    My computer, I see Documents of my name and the name of my son in addition to Documents (Shared Documents).

    When I save a new file in the My Documents folder, it is automatically created in the folder of Documents of my name, too. I can't delete them because they are system folders. I crossed my registry keys in the MUI cache and discovered that 4 of them did not exist in other accounts.

  • Need help implimenting MORE FLA in c ++ via XMP sdk

    I am apparently suffering from the brain stem major bitrot and generating a lot of brain coredumps, and I need help.

    I use the XMP toolkit sdk 5.1.2 in c ++ under gcc on Debian to impliment incorporation MORE FLA licensing metadata (reference: http://ns.useplus.org/LDF/ldf-XMPReference ) in images.

    I have no problem generating more consistent DFL xmp in the code for all EXCEPT for line inputs simple detail like "<RDF: type RDF: resource=" more: LicenseeDetail "/ >" in several places in the specification of the FLA, namely:

    < holder: more >

    < RDF: SEQ >

    < rdf:li >

    < RDF: type RDF: resource = "more: LicenseeDetail" / >

    < LicenseeID: more > http://plus-ID.org/AAA-987 < / more: LicenseeID >

    I can generate the appropriate memory then parse text to get an appropriate SXMPMeta and merge that, but I'd really like to be able to correctly generate the xmp in the code and would appreciate any help to prevent any new brainrot!

    I am sure it is simple and banal, but now I can't see the trees because of the forest... Thank you

    Hello Michael, thanks again for your questions and suggestions, Professor Garcia is one MORE volunteer who provided valuable assistance and advice in the original drafting of our license data Format specifications. His post here as a result directly of my request for his comments in response to this question raised in this thread, independently confirms that our understanding and our approach is correct.

    I confirmed that the items that you can't generate are not necessary in XMP and we have removed the examples listed in our spec.  Please note that although some of the examples in our FLA XMP specifications online, it lacked the attributes 'rdf:parseType', all these appear correctly in the downloadable example files. These unintended omissions have been corrected as well. We suggest using our downloadable example files.

    The suggestion in your most recent message about our version control was wrong but understandable.  The difference between the previous specifications and specifications in place at the time that you copied recently it is of course the result of ongoing changes in response to this issue, shared among other volunteers experts advising MORE.  A you have copied a few moments later, you would have probably found the 1.2.1 update version number.  That said, once we fixed a minor error in the presentation of the specification rather than a material revision to the specification itself, we may or may not choose to note this review.

    Please indicate any other matter related to the specification or to the adoption of the standards. As we have demonstrated here, we act quickly to solve these issues.

    See you soon

    > Toshiba Button support (why should I this program if my laptop doesn't have multimedia keys? OR maybe this program for something else?)
    You can disable it. If your mobile phone does not support the multimedia buttons then this tool is useless.

    > ItSecMng (although I have disabled the Bluetooth Manager to run when starting from this point still remains in the startup)
    I don't know what would make this process, but you can disable this in msconfig-> tab start Mr. If it would take in the future, then you could turn it on again.

    > Agent of filtering the Conexant high definition Audio (what is this program? Do I really need to start?)
    I think that this is necessary. It could improve your audio

    This is important. It s an additional saving of Toshiba option for Win 7

    This tool controls the FN keys.

    Hmm so you don t have two hard disks, then you can try to disable it too.

  • Binding controls reference

    Hello

    I would like to know if there is a possibility to bind controls of the same type of reference data, so that they contain the same data.

    This means that when you write to a property "Value" of the reference it automatically updates bound control without having to update "manually" go in a loop or using 'value (signalling)' / combination of the event.

    I would use it for a central display (one man control formatted) which can be activated to display one of the multiple values will cause updated (currently by the value property). For example allow a user to choose between analog input 0.7 then display the value accordingly (and keep up to date automatically).

    Best regards, W@Work

    Nope, no such construction. A better solution would be to pass data around, rather than controlling the references. In the loop of data generators, instead of write control references, to group the values and put the cluster in the notifier. Then, in another loop, pull the last notification, select the appropriate value and connect directly to the indicator. Control references are inefficent (they need a switch to the UI thread).

Maybe you are looking for
