How to find Property Nodes in other VI's

I am working on an application that I have inherited from others. It has huge, and in my opinion, very complicated and difficult to follow block diagrams. Here is the essence of the problem I am facing. On the main front panel there are various controls and indicators, but on the block diagram, none of them are wired to anything. So that means that (whomever it was before me) used property nodes on these controls and indicators. However, it looks like none of the references exist anywhere within the same .vi.
I have used the "Find reference" selection, but that only seems to work within the current .vi that I am already in. So I guess I have two questions...
1 Is there a way to search aross multiple VI's for a reference to a conrol or indicator?
2. To set up a program in such a way seems completely "bonkers" to me, as there is now no easy way to find where any of the controls or indicators are actually being set from. Considering there are something like 100 .VI's in this project, finding something is a bit challenging. Of course, there is not documentation of any sort. I am certainly NOT a labview expert. Perhaps there really IS a reason to set things up this way, that I am just not thinking of. Can anyone think of reasons why it might be a good idea to set things up that way? I would think that whenever possible you would want to wire directly to a control or indicator. And if you cannot do that, at least have the reference in the same .vi, and pass it into something else if needed.
Thanks....

Finding the where used cases for named queues and where obtained cases for vi server references to controls can get frustrating. The "find" feature in LabVIEW does allow text searches with several options.
Finding the String "<QueueName>" within the application instance on BD only and ignoring hidden stuff gets you to string constants that are exact matches to the queuename:
Searching for property node to a specific FP Object throughout a hierarchy can get devistating. Especially if the developer used the call chain to obtain a ref to the top level vi panel and pulled a rerence to a control that way
(DO NOT DO THIS) but I've seen it done:
Its "Legal" but almost garunteed to cause the guy who inherits your code to denigrate your parentage and intelligence. HOWEVER: that same text search for the control label text will find those string constants too.
Then document that code when you find out who is messing with what and how.
Chart it out over the app and e-mail that scribbling to the original developer too! Feel free to add a thank you note.

How to read the configuration of a FXP number via property nodes or other methods.

Hello all,
I am attempting to store in plain-text the value and configuration specifics of the LV FXP datatype. (please do not suggest I cast it to integer).
The ini config format does not support FXP. So we'd like to; using property nodes, interrogate the specifics of a FXP numeric control on the FP.
It appears this is not exposed by control ref's and property nodes.
Oddly enough, you cannot even interrogate the detailed type of an INT if it is a U8, I8 or I16 etc?! via property nodes, the deepest you can go is 'digital'.
Specifically, you need to know the following to 'reconstruct' a FXP:
1. Value
2. Signed\unsigned
3. Word length
4. Integer word length
Without this, there is a risk of corrupting the value during conversion.i.e we want to load initial FXP from disk at application startup. This is a critical application and we cannot tolerate rounding\conversion errors accumilating with numerous reads\writes of FXP settings.
It is odd that you cannot interrogate via property nodes the details of a numeric type. ie. you cannot 'discover' via the property node of an INT if it is a U8, I8 or any other type.

Jack Hamilton
PS: Don't suggest XML either....

..second post telling me the 'propertys' of a control have nothing to do with the value is bizzare - via 'properties' for a LV control is the ONLY way to configure the specific type of a numeric...so via the numeric 'property nodes' should\would be able to query it's configuration.
I do not see any way to set these things through the properties...
I think he means by right clicking the control on the front panel and configuring with the properties dialog. The properties are exposed there, but not within the property nodes.
Edit: You beat me.

How to set property nodes for each of the multiple y-axes?

In Labview 6i, I have set up multiple y-axes on an xy graph. I want to change certain properties of each of the 2 y-axes independently. I believe I can do this using "property node".
However, after I have created a property node for the xy graph, I realised that there is only 1 y-axis selectable from the list of properties. How can I set the property of the other y-axis then?
Thanks for the help!

I believe there is a property called "active graph"... this allows you to
select the active graph to apply the property changes to...
Later...

Property node allows you to programmatically read/write that particular property of associated object. For example, say you have a String Control, and you want to modify its 'Display Style'... for that you need to create and use that particular property node (of the String control).
Check the attached example.

Tentative bug report: property node (and other objects) resizes structure in which they are dropped even when this is not needed

This one has bugged me for a while, so, since I am in a mood to report annoying features, here it is:
On the diagram, when you drop an object that could have its size increased by user action (for instance a property node in which you chose "Value", which is a short property, but you could later change this to a "longer" one, which admittedly might require more space on the diagram), a case structure in which you drop it, will automatically increase its size.
Let me illustrate this with ONE example (can be reproduced with other objects such as enums, clusters, etc...).
Here is a simple diagram:
Note that I am going to create a property node from the front panel. This, for a reason that makes the beauty of this "feature", is very important. Apparently, if you create the property node from the diagram, nothing weird happens. The exact location where I will drop the node is not very important but needs to be close enough from the border.
Here is the result (LV 2011 but as I said, this has bugged me for a few versions already):
Basically, the case structure (and the whole diagram as a matter of fact) has expanded.
This is particularly annoying, say, when you are creating a diagram with 10 cases in a case structure and you start dropping things such as property nodes in each case: the structure keeps growing, and growing, and growing...
That also works with Event structure, and I am ready to bet, with other as well.
As I said, it is also not limited to Property nodes. I have noticed that this happens if you drop a cluster constant that contains an enum (presumably because some of the enumerated strings are longer than others).
I could speculate why this is the case, but that is not my job.

Actually, this might not be true. I found a variant of this behavior. With "Place Structure with Auto Grow enabled" unchecked, here is what I observed while dropping a property node on my diagram:
Before:
After:
This is the expected behavior. The Property Node is partly hidden inside the Case Structure I dropped it in. Now that's not what I wanted to do. I wanted to drop it in in the innermost Case Structure:
The problem is that now this Structure has grown (as has the whole diagram) to leave space for the whole Property Node:
It is a subtle bug in the sense that I tried to reproduce it on a new VI with a series of nested Case Structures, but it did not result in this behavior.
Anybody caring to comment?

How to expose model node to other dc

hi, now i want to expose model node to other dc. so i create data link from interface controller to model.in fact,the model node is exposed to other dc,but when i use it, i can not use it. please tell me the right way to do it.thanks

Hi Puneet
Write a method in the interface controller of DC1 where you have created your message pool. This method should take the Message id as input and return the message string.
Expose this interface as the public part and try accessing the message pool from this exposed method. Evey time you call this method just pass the message id.
Use the local component messagemanager to display the message.

How to Find the node or leaf node selected in Tree UI element:

Hi All,
I have a tree structure with three level design. We have a button, which will perform some operation on the specific node or leaf node on every level.
When we select any node or leaf node, we have action Onction getting called. But what we want is that, after we select the node or leaf node, we press a button below the tree design and perform some operation on the node selected.
But how to get information that on Application , which node or leaf node has been slected ?
Thanks
PG

Hi,
Found the solution.
Juts keep on reading all the nodes, system gives the complete path of the tree by using Lead selection and then we can use this path to peform the update operation on tree structure.
Thanks alot for the hint.

How to find which programs (and other objects) use the field LGORT

Hi, Im an Abap freshman, and I have been asked to search all programs and objects that use the field LGORT (Storage Location), regardless of what table it is in.
Is it possible to do it using the "Where-Used List"?
This will be important since a new Storage Location will be created for MM, and we have to assure that no other programs that reference to it will be affected.
I would appreciate any help. Thanks!!

Hi George,
Go to transaction SE11, choose radiobutton Data Element then enter the name LGORT. Now using the where-used-list in the toolbar, choose programs checkbox in the subsequent dialog and press enter. It should show all programs using the field LGORT irrespective of table name.
Hope this helps.
Cheers,
Sougata.

How to find the table in which data from a structure sits

Hi,
I want to know how to find the exact table where data sitting in various structures during runtime are stored.
For instance,in ME23N we have various tabs and data in those are held in various structures. This we can see by checking the technical setting of each field.
I want to know in which table the data is actually stored for each field and how to find them.
Any other means other than using "WHERE USED" option?
Thanks
CM

After checking for technical field from the screen, when you reach out to structure, you can dbl click on the particular field's data element. From this data-element you can get to know in which tables it is used. Also if the data element refers to some master data field then you can check out its domain and in the domain you can refer the<b> value table</b> for that domain. This is what i will do if i am not sure about anything.
Hope it will help a little.
