Is there a Property Node for Transition Location?

Is it possible to change the Transition Location of a plot in a Digital Waveform Graph by property nodes?
I'm looking for that item on property nodes but I don't find it.

I've searched through the properties for a while now and I can't find anything that seems to work. I can't find a property for Think Line Location either.

Tree Control Property Node for Accessing "Child Text" String Array

When adding items to a tree control using the EditTreeItems invoke nodes, the inputs include "Child Tag", "Item Indent", "Child Only?", "Glyph Index", "Child Text", and "Left Cell String" as can be seen in this screenshot.
There are property nodes for the tree control for accessing each of these elements, except for the "Child Text", which is an array of strings. It is possible to access this data as outlined in this forum post, but this method is somewhat involved and round about.
I suggest that a property for the Tree class be created to access the Child Text array directly.

The work around only works if you do not have an empty string element some where in the middle.
At lest could the "Active Celltring Property" read return an error when you have gone beyond the end of the array.

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...

Question(s) about the Active Cell:Position property node for a table control

Hello,
What determines the Active Cell Position property node for a table control? I have this in my code and I am displaying its value to a front panel indicator. The value displayed is always set to 0,0. The help for the property node say that it is "read -only" so what sets the value of Active Cell Position for a Table Control?
Regards,
Kaspar
Solved!

You set the active cell with a property node. Once you select an active cell, you can do specific things to that cell and that cell alone, things like set the background color.

How can I make a "property node" for a VI?

Hello!
If I add a boolean button on the FP then I am able to make a property node for that button in the Block Diagram. But how can I make a property node for a VI? I have several VI:s an that together is one program. What I need to do is to verify what kind of VI some of my VI:s is. I need to verify if it is .exe or .vi-file, and if it is .exe then I want to disable run, abort, run continuously bottons otherwise not. I have hard that this is possible to do programmaticaly but I can´t figure out how. I am aware that I could do that manually in the File->vi properties->customize->windows appearance but theese choises makes it last forever.
I want to be able to stop and run and everything if it is a .vi file, but if it is .exe-file then all those buttons should be disabled.
Anyone have an example on this?
In an other message at this Forum I read "You can use the `Front Panel Window. Allow Runtime PopUp`" property to disable run-time shortcuts menues programmaticaly, but still I dont know how to create this property node.
/Amir

You really shouldn't open a new thread. If you don't understand something, ask and we will explain it.
Like I said in the other thread, you can check if you are running in LV or an EXE by using the Application>>Kind property. To get it, place a property node (from the Application Control palette) on the diagram, click it and find the property.
To set the properties for the VI, place another property node, right click it and select Select Class>>VI Server>>VI. You should have the properties you want under Front Panel Window.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf). I believe chapter 17 of the user manual explains about programmatic control of VIs.

Using One Property Node For Multiple Controls/Indicators

Question for all you LabVIEW gurus. Is there a way to create 1 property node that is used for multiple indicators? For example, if I wanted to display the same value on 10 different indicators using the property node - value function do I need to create 10 separate property node-value instances for each indicator? Or is there a way to tie all of those indicators to only one property node?
Thanks!

Hi hobby1
You could create a cluster, and inside in it put all the indicators, see the image attached

Why can't I create property nodes for item in STRICT typedef cluster?

I've tried this in LV7.0/WIN2k and LV 7.1/OSX - both versions work the same.
I have a TYPEDEF consisting of a cluster of items A, B, and C.
I have a front-panel instance of this typedef.
Under certain conditions, I want to disable and gray Item C, because it's not applicable.
So I need a property node connected to item C.
If the typedef is STRICT, then I cannot create such a property node - the menu item to create anything is just not there.
If I change to NON-STRICT, then I can create the property node.
I can change it back to STRICT, and the property node works just fine.
The question is, if the nodes WORK normally, why can I not CREATE one?
If there's some sense behind this, someone please point it out to me...

Blog for (mostly LabVIEW) programmers: Tips And Tricks

I agree with you, It would be nice to be able to keep the non strict typedef auto-update and extend it to properities which effect the look of a control. I am not sure why you can change the properities on a strict typedef. A strict typedef should have private properities (can only be changed from within the definition and no public other vi scope for writing these values. I have in the past used a custom control for presentation purposes and contained the structure of the data to be displayed within the typedef cluster. This is not all that automatic since we need vi's to convert between the definition and control. Seperating data structure from presentation is much like XML where the file only contains data structure and a reference to a style for presentation. It would be a very nice option to allow nonstrict typedefs to have an additional auto-update properities which could be toggled on and off. I would be curious to here others opinions on how to keep data structure and presentation consistant across an application without being tied down to a strict typedef (allowing the optional change of teh presentation at runtime).

Use of multiple property nodes for GUI manipulation

I have a LabVIEW 6.0.2 application where I'm using 14 different property nodes in the main loop. All of these have to do with GUI - hiding buttons when "X" isn't pressed, disabling and greying out controls if <0, popping one button on top of another depending on the mode of operation, etc, etc. While this works fine, the program is getting slow. I've noticed that using the old 2-D buttons works faster - things update faster and redraw quicker. However, more to the point, I once read that if you have to use a lot of Property Nodes like this, that you should bundle them into a sub-vi, thus replacing what would be Property Nodes with references. How does that make it faster?
Richard

Not sure if bundling them into a sub-vi by itself would make it faster. The nodes in the sub-vi would still have to access the user interface thread, and that's where the slow down comes from.
When I use any property node, I put it in a case structure and only write to it when needed. You just need to be able to detect when the value being written is changed from last loop iteration. It's useless to constantly rewrite the same value (doesn't have to be the "value" property) to the node.
Bundle them into a sub-vi and put the change detector, case structure and nodes in the sub-vi, this should help speed things up a bit. Assuming of course that the nodes are the slowdown. It may also help clean up the diagram a bit.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

Property node for a chart with multiple axes

I have created a chart with two y axes, one for each of two data sets
that I am plotting. From the front panel, I can view the properties of
the chart and adjust the scales of the two axes separately under the
Scales tab. I need to, though, adjust the maximum and minimum of these
axes programmatically. How can I create a property node that refers to
one of the two y axes, and how can I specify which axis the node is
referring to? If create a generic YScale:Minimum property node, I get
an error.
Thanks for the help,
TJR

"...YScale:Minimum property node, I get an error."
That is curious.
You can specify the active scale for which the property will be applied.
The attached demo (in LV 7.1) illustrates how to do this by fist setting the index of the active scale and then updating its property (property nodes execute from top to bottom).
What error do you get?

Is there a best practice for multi location server setups including mac mail server?

Afternoon all,
Last year I setup a client with Snow Leopard Server including hosting his mail on the server with Mac Mail Server and calendaring. He now has plans to open other sites with the same setup, how can this be done using Mac Server? The implementation of a new server on the new site would be straight forward my concerns / question are:
1. How would the two servers communicate?
    a.)Do they need to communicate?
3. How will mail across the two sites work?
    a.) How will DNS work for email internally?
    b.) How will DNS work for emai externally?
4. How will calendaring work across the two sites?
Is Mac Server the best platform for moving ahead with this type of business need?
Any help or direction would be greatly appreciated.
Anthony

Camelot,
many thanks for the speedy reply. Your comments are very helpful thank you, if I may I will give you some for information and some other questions.
The offices will be from 5 miles to 25 miles apart, the new office and ones that follow will be considered as branches of the main office for example the company name is Sunflower and it serves area 1, then new will office will serve area 2 and so on. So in theory I could leave the main server domain and mail mx record as sunflower and then add further servers as 2.sunflower.com, 3.sunflower.com as domains and mx records? This would then provide unique mail records and users within the organisation such as [email protected] and [email protected], which doesnt look to good I would prefer all users to be name@sunflower how can this be acheived?
With regard to user activity in the whole users will be fixed but their will be floaters such as managers and the owners that may at times float from one office to the other and would beneift from logging into any machine and getting their profile.
I have thought about VPN's as I have acheieved this type of setup with Microsoft server products, I have found speed issues in some cases, how can this be acheived using OS X, are there any how to docs around? In the Microsoft setup I acheived this using netgear VPN Firewalls which ofcourse adds an overhead, can this be acheived using OS X propietary VPN software?
So ultimatley I would prefer to have the one domain without subs "sunflower.com" and users to be able to login to their profiles from either location. The main location now will remain as headoffice and the primary location and the new will be satelites.
I hope that covers all of your other question, again many thanks for your comments and time.
Kind Regards
Anthony

Property node for case structure

Is there any way to programatically pull out the list of cases (strings) from a case structure at run time?

Thank you tbob and tst. I do use the enum "trick" in other places (I once saw it used in an example somewhere) and I am nervous about the Selector Strings property available through scripting after reading about it on the LAVA forums site (I am a novice LabView user and I mostly didn't know what they were talking about).
I have a VI that processes "tags" embedded in various text fields that many of my collegues use. As an example we have a custom front end to the LabView simple error handler that processes our custom error codes and handles timed popups, writing to the device error log, etc. The default behavior can be modified by inserting tags (<popup 60> for a dialog box with a 60 second timeout or <no device log> to supress writing an entry to our device error log) into the "source" string of a standard error cluster -- just like the <append> tag used by the Simple Error Handler.
In most instances there are only a few tags so I just use a case structure in the "tag processing VI" to select the desired action indicated by each tag. When people are parsing their strings for tags, they like to have a qick and easy way to test if a string is a vaild tag. I provide a separate "validator VI" to do this. I frequently add and remove tags from the case structure as things evolve, but I often forget to update the list of valid tags used by the validator VI or some one runs into an older version on another machine. I wanted to have the vaildator VI access the case structure on the tag processing VI to get the current list of vaild tags.

Is there a line style descrepancy with xy graph property nodes?

Hello.
I am attempting to display mutliple bar graphs in a single XY graph control. To color-code and label each one, I set up a for-loop and call each active plot to set the color, plot name, etc. The problematic thing is that when I define the vertical bar graph type by-hand, at the control on the front panel, I have 5 vertical plot style options. The fifth one produces the best results. When I try to set this property node in the block diagram, I have only three vertical plot style options. Is there a way around this?
Appreciate any fedback.
Best,
Mike

Hi Mike,
I read the property node for the bar plots (after having setting it by hand to the one you like) and it appears that the value of that bar plot is 8. I also set it to a different bar plot by and hand then wrote "8" to the property node and that does seem to change it to the last (left to right) vertical bar graph. I am running LV 7.1. If you look at the context help it does seem to indicate that the only values for vertical bar graphs are 1-3 but try writing "8" and see what happens.

How to change value of constant for "Disabled" Property Node?

Hello all,
I'm attaching a vi example of what I'm wanting to do. It is happening during the event for "Left Selectorrogrammed 1: Value change.
Basically I've created a property node for a LED boolean control. After it is clicked, I am wanting to disable it so the user cannot change the value (I have a reset all button for use on that).
I've created the property node for this control for Disabled. When I am in the block diagram, I change it to write mode.
I've rt clicked on it, and said "create constant", which it does. However, the constant comes up every time as "Enabled". I've tried clicking all over this constant, and looking through all the properties, but I cannot figure out how to toggle through the values or set the value of this constant from "Enabled" to "Disabled".
I see where you can edit the items of this constant...but I'm guessing there is some way to toggle this constant to the value you wish....any suggestions?
Thanks in advance,
cayenne

To change a constant value your cursor needs to be in the "finger" mode.
You can select this by holding down shift and right-clicking on the diagram - then select the finger.
Another way is to set Automatic Tool selection:
Tools >> Options >> Environment >> Lock automatic tool selection
With this option, LabVIEW will choose the tools for you.
Play with it a bit to see how it works.

Is there a property for mixed signal graphs to control Y scrollbar visibility?
