CTRL val get reference returns zero refnum
I use 'ctrl val get' in a vi. The value it gets is a bunch of references, the references are returned with a value of zero. Is there a prohibition against the use of 'ctrl val get' by references?
Adde a probe earlier to see what Ref was not valid.

Programatically register values of control only works with Ctrl Val.Get all (not recommended)
Hello
I just downloaded "programmatically save 86 vi of https://decibel.ni.com/content/docs/DOC-3551 control values.
This works. In the recording, but there an invoke with Ctrl Val.Get All (deprectated) node structure of the event. I thought that I would get rid of the obsolete reselecting the control method get all. Of course it was more an (outdated) at the end and the top of the page, little changed from pink to yellow. However when I run and load a file that is saved I get: error 116 took place to Unflatten chain... Possible reasons:
LabVIEW: Unflatten or stream of bytes read operation was in pain due to corrupted, unexpected or truncated data.
A few questions:
If I were writing this thing without having to download the example it wouldn't work. Any ideas how I would work in LabVIEW 2011?
The example is quite old, people would use another method of loading and storage of the parameters in a VI these days?
This VI crashes after a while. Is it because he has two event Structures in a loop or because there is no case of timeout or what? (I am not really concerned about why it crashes but if someone knows the answer without wasting time running it I'd appreciate it)
Thanks for the tips, things that I can draw from this
The old ways worked with a data type that was {name, type descriptor, flattened data}. The use of new methods {name, variant}, to adapt the code to work with this data type. Also, you cannot use the old data with the new code files.
I'm assuming that the VI is lock because you have two structures of event in a loop simple (it would make sense, since each structure must wait for an event is to occur), but I'm not the code itself, I can't be sure.
With respect to the other options, I generally without saving all the controls on a front panel, but when I want to record a bunch of controls, I usually use something like this, which can also work if you collect all the controls of the FP. There are also links to other similar things in the more 'like this' section with the page.

How to use ctrl val.get on a Subvi running?
Hello
I try to use the Val.Get of control 'Node to invoke' method on a Subvi running to get the values of certain controls to display in a tab. Does she not get the value of the control, it is not updated during the Subvi execution. This particular Subvi displayed a few temperature readings (because now it is just connected to a generator of random numbers for debugging reasons). I have attached my files and I'd appreciate any help I can get. Ultimately the purpose of this exercise is to display a large number of readings of temperature on several tabs with the tab before showing some summary information.
Thanks in advance,

Change Ctrl.Val.Get or binary write format of LV8.5 until 2014
Hello
I have recently updated from LV8.5 to 2014 and a problem of compatibility. I used the Crl.Val.Get method to get an array of values and save them in a binary file:
to read later with a binary read:
My problem is that the files generated in this way with LV2014 (64-bit) cannot be read by LV8.5 (32 bit) - the result is a "LabVIEW: Unflatten or stream of bytes read operation failed due to corrupted, unexpected or truncated data" error or an application crash.
Writing binary VI changed of LV8.5 ro 2014? Is this a problem for 32/64-bit? Oddly enough LV2014 reads the files generated with LV8.5 without problem. Is it possible for me to this LV2014 program to ensure backward compatibility with LV8.5 (something that I need for a prolonged transition period).
Kind regards
Casper
About, unless you set the binary file format exactly (for example define how you store the data in the file until the byte level) I'd be dubious on the file is readable in the new/old versions of LabVIEW - especially if you are using types of complex data as of the beams.
Dealing with backward compatibility would be either define the binary file format and work to that or use a file format string in function (e.g., JSON, XML, INI) for which you can write a compatible rear parser. The OpenG library has screw for saving/loading of the controls in the Panel before a VI in an INI file, for example (even if OpenG stop supporting, it's a format string in function, so you can always write your own parser if you need to in the future). I know that don't helps you you in your current situation, but maybe something to keep in mind for the future.

Call data from Ctrl: Vals node
I am trying to extract the individual elements of the Ctrl Vals invoke node.
The front of the VI being called is a string and 4 double rooms:
I am calling the VI and try to read the values as follows:
The error I get is:
Could someone please explain what I'm doing wrong here? I want to just correct the 5 variables from the front of the VI (string and 4 double rooms). I try to extract it as a cluster only because that context-sensitive help mentions that data Variant is a cluster. I would ideally unbundle this as well, but I can't even the cluster again.
The code is also incredibly simple, so I attached the VI. If someone wants the acutal VI, I can attach it to a future post. Everything I do called two nodes Invoke to run then get the values of the façade. And finally try to extract the variables based on Variant type.
The data type of "val Ctrl. Get all the ' is an array of clusters containing ctrl name (String) and ctrl (option) value.
You can not (AFAIK) convert these data directly to a cluster of string and double rooms.
Are the names (labels) and the called VI controls fixed and known data types? If they are, you can select each by name and convert the correct data type.
I once stumbled on a VI (openG, I believe) who would get the data type of a Variant, but I can't find right now...

Table of index always returns zero when reading the table 3D
I have a 9 x 2000 x 5 table table 3D diamension. I have this table filled with data and when I try to read a data point unique on the table the function Index Array always reads zero. I place a probe on the 3D input array and when I put in the index of the probe to the same data point the probe shows the value stored in the table. I also have an indicator showing the 3D table and it displays data in all locations. For example if I try to read the location 0, 144.0 in 3D it array always return zero. Yet I know that the value of this element is 6.8616E - 5. Each item I try to retreave table gives zero.
Anyone saw the Index room table this kind of behavior?
Problem solved. As usual, it was pilot error on my part had knocked down the lines of lines and columns.

Any idea which function Essbase or a combination of function can be used to get the level zero members of a list of members. I know that @RELATIVE or @DESCENDANTS cannot be used.
If you want to fix on all level 0 members in a member set, then maybe @ILDESCENDANTS will work for you. Something like: @ILDESCENDANTS (@LIST (members), 0)

Get-VMHostSnmp returns nothing
Hi all
I need to get out a bunch of SNMP parameters for some 5.5 ESXi hosts.
This bit is easy. I say that because when I run the command set-vmhostsnmp to add the targets and community names, no error is returned.
It's when I try to check the settings, or search the SNMP settings on different hosts that I run into trouble.
I want to add that I tried the following on PowerShell (v3), Powershell ISE, with VMware PowerCLI (5.5 Release 1).
Always with the same results.

When I put something inside the brackets, I get the following
The 'get' method is called with parameters '1', but the number of parameters expected is '0'
Any help that can be offered would be appreciated.
Thank you all
Problem solved.
I've updated since PowerCLI 5.5 Release 1 to PowerCLI version 5.8 Release 1 and the get-vmhostsnmp command now works.

You can also use MAX based on your requirement... What do you do, if there are multiple records ID? Based on that you can use as

Table of clusters: get references to all clusters
I want to get the reference to each cluster in a cluster network and through its controls and save their values. I enclose the code that I have tried, but it only gives me the reference to a cluster that is under development. The code must be the job for any generic array of clusters.
In fact, it returns the reference to what is in the location specified by the index display. So, you can change the property of Index values to iterate through the cluster and get each subsequent reference.
You said "save their values." Save them how? Save to the folder? If values can be recalled at a later date? If so, there are easier ways to do it. For example, you can Flatten in XML format. In addition, OpenG has a set of screws to save to the file clusters.
