Slider value corresponding to picture ring control

Hi guys.
I am using LabView 2009. Currently I have a picture ring control in my VI ready for me to create an animation but I am suppose to have a numeric slider beside the picture ring control so that whenever my animation starts, my slider value would change. For example if the first image is being shown by the picture ring control then my slider value would be 0, second image shown by the picture ring, the slider value would be 15. I currently do not have any idea on how to achieve this so I do hope to receive all your prompt replies.
Thanks.

This is what I have done so far, but I can't seem to connect the stop button to the event structure and how do you also change the to ?
Hope to get your prompt reply.
Thanks.

Can I load pictures for a picture ring control at run time?

Hi all,
is there a way to achieve the above mentioned behaviour? Changing the graphics elements of a picture ring control or indicator at run time?
Best regards,

You can do that with the picture indicator. I have written a slide show program in LV and it works quite smoothly. If you start to see delays, it is probably due to file read time rather than the display. Read one or two files from disk ahead of when you will want to display them. Updating the display from memory should be fast.

Picture ring control

Hi,
I have never used picture ring control or indicator ?
I have given a review work, a nameplate specification data is obtained from database and is stored in a global.
using proper indexing a number is given to picture ring indicator, and corresponding image is obtained.
How does this work any explanation?

You copy an image to the clipboard and then you right-click on the picture indicator and select "Import Picture from Clipboard". This is in the Help.

I use LV 8.5, and the help on Picture Ring HERE shows that it is part of 8.1. Was it removed?
Edit:
Can I remove this post? I just found it. I have to be on the Front Panel, and I have to be searching the Classic section. I'm ok with deleting this post now, so others aren't bothered with it. Can that be done?

Assigning value to picture in picture ring control

Hi,
i made a picture ring that contains 23 images. I'm measuring a real-time signal and want to assign (for example) picture 1 to measured-voltage-value of 0.5 V, picture 2 to 1 V, picture 3 to 1.5 Volts, etc.
How do i do this?

It all depends on your code structure.

Custom picture ring: disabling the popup menu

I have custom picture ring controls -classic ones- and they work fine when clicking the increment and decrement arrows, however clicking anywhere else on the picture will cause a small popup to appear -like the ring menu control- which shows all pictures. I'd like to disable this during runtime; how to achieve?

Hi Faust,
it's just a picture ring with a decoration on top, but here you go...
I only set the inner area transparent and left the border of the decoration in black so you can actually see the decoration...

Ring Control Output is the Item name and not the value

Hello. I am new to Labview. I am experimenting with labview and just creating simple VI's to learn about the software. I have placed a ring control and attached an indicator to that ring control. I thought that the purpose of a ring control was to select an item and output a value. For example, I have placed 3 items in the ring properties (Red, Blue, Yellow) and given those items values of 1,2,3. But when I run the VI and select Blue, I was expecting the indicator attached to the control to read 2 but instead it says 'Blue' (same for other items as well). What am I misunderstanding here or doing incorrectly? I have also attached a screenshot.

Your indicator is another ring that has the same name value pairs, so it is going to display the name associated with the value. Delete the ring indicator and just drop in a regular numeric indicator. Then it will show you the value.

Ring Control/Indicator Min/Max Values

Is there a simple way to retrieve the minimum and maximum values of a Ring control or indicator?
I'm not looking for "Data Entry Limits", so that hasn't been useful. The only thing I've been able to do is use the "Strings And Values []" array, however even THAT is problematic, as it returns an array of clusters. To use "Array Max & Min", I have to use a for loop to index the array, and create a new array of just the Values.
Is there either a way to just get the Min & Max, or an easier way to get an array of the values? Ring controls have both a "Strings []" and "Strings and Values []" property, why don't they have just a "Values []" property? Perhaps there's a way to UN-Index and UN-Bundle a Cluster Array?
I'm using LabVIEW 8.5.

I agree with you that a reverse of "index and bundle cluster array" could come in handy. I am pretty sure that the way you are solving this problem is the best. The only other way to solve it I can think of is to convert the array of clusters to a variant data type and then flatten this to a string and parse the string for the data. This way is a lot more cumbersome and does not get around having to use a loop. Maybe someone else can think of a better way, I am interested to hear if there is.

How do you overwrite values in a ring control?

Hello,
I have a Ring Control (Text Values) in Labview 2009 and it is programatically populated with 20 items. The end user either selects from the items in the list or populates it with a new item based on a checkbox for adding new item. What I want to do is when the 20th item is entered and the user selects the checkbox for item 21 to be added I would like to rap around to the first item in the list and overwrite it. Is this possible and a sample vi would be great to demonstrate how this is done. Any help would be greatly appreciated!
Thanks in Advance
Charlie

Replace Array Subset. You will need to keep track of which item to replace in a shift register. I would also keep the list in a shift register to make your life a little easier.

The fact that the error is gone when you don't connect the indicator is good. Even better it is super.
It means the compiler removes that specific node from the execution stack if it isn't needed.

Using picture ring with multiple controls

I am using a picture ring with 21 pics in it.each pic represent a state, I am using a flat task structure to execute this states. the question is how can I increment the picture ring from inside every single state/task?
regards
Luis

if you are already using a state machine you should not use a flat sequence structure. you can make your program more useful just by using the state machine itself and telling it which fram to go to when completed I have attached a VI that explains this eaxample

How to change the numbers of items in a ring control in run time ?

Hi !
I would like change the numbers of items in a ring control in run time, but I can´t.
Thanks.

Hello blaze,
did you try the "Strings And Values []" property of the ring?
LabView7.1 help says:
Array of clusters containing the strings from which you can select in the ring control
and the numeric values for each item. Use the Strings [] property if you do not need to
assign specific numeric values to each item.

Maximum file size in picture ring?

Hello folks!
I am planing to use a picture ring with a quite big amount of data needed.
My question: is there a maximum data size that i can embed in a picture ring (number of pictures or overall file sizes)?
Thanks!

If you have enough memory to keep all the images open simultaneously, then something like this might help. Put all your images in the same directory on disk and have no other files in that directory. Then use List Folder from the Advanced File palette to get an aaray of the filenames. Feed that array to a for loop where you open all the files and place the images into the pict ring. I have written a "slide show" program which does this. Never tried it with 400 images though.
If you do not have enough memory for all the images, then you need to manage the iamges much more carefully.

Dynamically changing elements in an array of menu ring controls

I have an array (32 rows, 5 columns) of menu ring controls. When a menu selection is made in the first column of any given row, the contents of the menu ring for the subsequent columns (same row) may change. If this is possible, how would you do it? Thanks.

A ring is just a number as far as LabVIEW is concerned, so the underlying cluster need only store numbers, not rings.
In the example I posted in a linked thread, where controls are moved around on top of a table, you need only one ring control. Each time you show that ring, you can assign a new set of strings and values to it, using the Strings and Values property. You can decide what set of strings to show based on the existing data in the cluster, which will get updated each time you change the value in a cell of the table. Does that make sense? I don't have time right now to put together a more detailed example than what I've already uploaded in other threads, and it's only a small change to that.
You update the menu ring at the time the user wants to select a value from it, not at the time the user changes the value that determines what set of menu items to show.
