Regarding Array to Multicolumn Listbox data's manipulation
Hi - I want to display the above mentioned array in muticolumn listbox with 2 columns , first column needs to be belongs to array [0] (Date and time ) and second column needs to be belongs to array [1] and array [2] ( Cone and Vane strings).
I have tried to implement the same, please go through the attached VI and I cannot make the above mentioned array data's into two column multi column listbox data's (that is , can't able to display the array [1] and array [2] data's in single column.
Please let me know the solution to resolve this as soon as possible.
Thanks and Regards,
Dinesh

Well, your VI is a complete mess and has several CPU burner loops that run as fast as the computer allows. There is also a lot of duplicate and overly complex code. Programmed correctly, code with all this functionality could probably fit on a postcard.
Anyway, for just building the multicolumn listbox, here's somewhat simpler code. Hopefully you can adapt it to your problem.
Note that you probably want to add only one row at a time, and you only want to add to the listbox and save to the file when new data arrives and not millions of times per second. Try a queue, for example.

Filling large array into multicolumn listbox
Hi,
I need to fill a multicolumn listbox with a large array. I feed a 2D array into the ListNames property. The problem I am having is that if the array is large (+1000) it is taking forever to update the itemnames. Is this because the listbox is going through a resize? Is there someway to intialize the ItemNames array to speed up the insertion. It is also slow if the next array insertion (overwrite) is a small array.
thanks MichaelHi Michael,
Please take a look at the attached VI.
This VI allows the user to programmatically (during run time) write data to a multicolumn listbox. The VI uses the control reference to a multicolumn listbox, so this VI will work on any multicolumn listbox. The VI has inputs for the 2D array (of strings), and a start location (row and column) where the zeroth (top left) element goes. The VI returns the end row and end column of the multicolumn listbox. This is useful for writing successive entries to the listbox.
In this vi, I am currently writing a 1000*10 2D array to a multicolumn listbox and it runs very fast.

Ankita A.

is there a way to extract data from one of e.g. 7 rows from the multicolumn listbox?
All the data can be extracted by creating a property node and read the Item Names property...then you get a 2D array of all the rows and columns. Wire that array into an index array function and input the row you want (e.g. the listbox value, if you want the row currently selected...)...that's it. See attached example.

Read data in the first column selected in a Multicolumn listbox
When a row is selected in a multicolumn listbox (1 item), how do I go about reading the data in the first column?
Solved!
Go to Solution.The multicolumn listbox itself is numeric array data type. If you have allowed selection of only 1 item and selection mode of select entire row, it returns the row number. Use the "Item Names" property node to return a 2d array of strings of the items in your box. Index it by the row from the value of the listbox and column 0. See attached code.

Entries into Multicolumn Listbox/Safing Data in .txt-file
Hello. I haven't found anything helpful for my problem or better to say problems. I have to do a task that I have no idea how to solve. It isn't helping that I was never good with programming. Here is what I have up till now:
I want to write seven strings indivudally into a multicolumn listbox with seven columns. The first shall be a running number, increasing for every row. For this I'm using right now a Case Structure. And there is my first problem. I don't know how to realize that whenever a row is completed the next string is written into the next row instead of overwriting one in the completed row.
This has to go one for as long as the user wants to. Then there has to come a Pop Up Window - if that's the correct term - and shall ask the user if he/she wants to safe the created list into a textfile. And that's my next problem. I have no idea how to program that.
I know it's probably rather easy to program these things in LabVIEW 8.0 (which I'm using) but as I've already said I'm anything but good in programming at all and to make things even more complicated I don't want to do this task, therefore not putting all my energy into it as a result.
Please, can someone here help me?Does it have to be a multicolumn ListBox?
Seems like a table might be more appropriate, if it's only for display purposes.
Either way, you need to use a FOR loop inside a FOR loop to generate a 2-D array of strings.
The INNER loop generates the strings for each column in a row, the OUTER loop generates each row.
You wire the 2-D array directly to a TABLE indicator, or to the ITEM NAMES property of a ListBox.

i want the data to be transfered in MS Powerpoint like what multicolumn listbox act in my vi.
(would you mind if i will ask for an example)
Thank YouGood morning:
I think you might have an easier time doing this with a Powerpoint macro than with Activex. You can save your data to a spreadsheet file, and then let the PPT macro read that file and format it the way you like. You will have to have two programs operating simultaneously, but that shouldn't be a problem.

Drag and drop from Multicolumn listbox to another Multicolumn Listbox
how do i drag and drop from Multicolumn listbox to another Multicolumn Listbox?/...any example..
use LABVIEW 8.2.1
regard's
eyal.To drag and drop within the target listbox you'll have to add a Drag Starting? event for the target listbox and register that drag data with a different adn unique Drag Data Name, then in the Drag Enter? event check for that data name as well before accepting the event, and then in the Drop? event for the target listbox handle the new data name as well. You can use the Point to Row Column invoke method to determine which row, column, or cell is being manipulated. I've created a VERY crude example of this, but you'll have to get more creative with how you handle the moving of rows, columns, etc. for the target listbox, but I think it gives the general idea. Hope this helps!

Help - Edit cell of a multicolumn listbox at run time
Hi All,
I am populating rows and columns of a multicolumn listbox from a file at run time. However, after the data is loaded in the listbox I want to have the option of changing cell value.
Can I do that? If so, how?
I appreciate your time and help.
Thanks,
MimHi,
You have to use the property item names witch is a 2D string array.
Then replace the elements you want to change in that array and write it back to the table.
Check attachment.
Hope it helps,

How to write into multicolumn listbox during runtime?
Hi,
I am able to edit into multicolumn listbox. But i am not able to write into empty boxes... How to do that???
Regards,
AmitHi Amit,
Have you initialised the item names with any default values? If not try initialising the item names to a 2D size that will be large enough for you're requirements. Once this size is set in edit mode you can't enter data at runtime outside of this initialised area.

Is it possible to make a line of a multicolumn listbox active?
I currently have data entered into multicolumn listbox. While the program is running, is it possible for a row of the listbox to be selected and then give the index number of that row? From there I will want to use that index number to reference other arrays, but right now I'm just dealing with getting the index number I need from the user's row selection.
lmtis wrote:
The I32 is the default numeric constant, I didn't see the need to change it for this purpose.
You missed my point. The output datatype of the Value property node is an I32. You are wiring to an I32 indicator, but shoving it through a TypeCast function. This is pointless.

How to hide multiple columns in multicolumn listbox like as an excel sheet?
Hello All,
I have large amount of data that is to be displayed on multicolumn listbox. After displaying that, I want to hide or delete some columns from listbox in runtime.
I know how to hide one column using active cell property node. But I want to hide multiple columns. I am using LabVIEW 2011.
Thanks in advance.
Thanks & Regards,
ManishaThank you so much.
But I have total 12 columns and I don't want to delete columns serially. I want to delete inbetween columns, like in attached VI I want to delete column A & D only.
And in this user have to select it from frontpanel. I want this is to be done as in excel, like we select the entire column and either we hide it or delete it. One more thing I want to clear the data in multicolumn when I next time open my VI. How to do that?
I hope am clear in explaining my problem.
Thanks & Regards,
Manisha

Using a Multicolumn Listbox To Retrieve Selection Items
Hello, I want to use a Multicolumn Listbox as a control. This control will popup to a user and the user can select as many items (rows) as they would like. When they are done with selecting which items (rows) they would like to select they hit the Done key to end the selection process. Programatically, I then would like to create an array for all of the items (rows) selected. I have two headers: Test Code and Test Name. I would like to programatically create an array with the Test Codes and the Corresponding Test Names.
I think I can do this with property nodes but I am a bit new to using Listboxes. What is the best way to do this?
Thanks!Hi,
Please check attached VI it may help you!!!

Set column width of a multicolumn listbox in LV touch panel module
Hello,
I am trying to build an application using LV Touch panel module 8.6 and I am having a problem with multicolumn listboxes. I am setting the the width of the columns by clicking and dragging the separator between the headers, but when I transfer and run my application to a winCE controller the width of the columns is the same for all columns (and very narrow actually).
Does anyone know something about it?
I also noticed the following two problems. When I transfer my application in the winCE controller, the line and column separators are disappeared and the column headers are also disappeared, although I have set them to be visible in my vi.
Thanks in advance.The issues that you are having are because the LV touch
panel Module does not support "Moveable column separators" and
"Row and column headers". The limitations of using a touch panel are available
in the LabVIEW help file.
A possible workaround may be to use a series of arrays with a string data
type then using a single scrollbar control multiple property nodes.
I have attached an example.
I hope this has helped.

Trabajar con Multicolumn Listbox
Hola a todos...mi pregunta es la siguiente:
me encuentro realizando una aplicación donde almaceno en una base de datos el nombre de unas variables (temperaturas), mas no el valor.
en la primera columna muestro los datos de un Select que hago a una tabla donde estan los nombres de las variables (select nombre from tabla), mi pregunta es la sigiuente como puedo colocar en la segunda columna del Multicolumn Listbox el valor de las variables que tengo almacenados en un array que lo capturo en tiempo real.
el Multicolumn Listbox quiero que se me vea así:
Multicolumn Listbox
variable valor
Temp1
60
Temp2
80
Temp3
30
Temp3
40
gracias...Hi pineda,
if you have all the names in one array and your temperature values in an other array you can use the "build array" function to get a 2D Array of it. After that you can use a property node of your multicolumn listbox and write the data into it.
Hope it helps.

Currently, I have a User Input Promt delivering values to a Multicolumn Listbox.
I need, when a value is True (externally from the while loop), for the multicolumn listbox to spit out the top cued value as a Comma Seperated Value (CSV) string.
Example:
1. External value is true
2. Upper most row of values from listbox taken and placed into CSV string
3. String sent out of while loop (external)
Thank You,
Jim

CSV from Multicolumn Listbox.vi 64 KBWhich part are you having problems with, since it's not clear:
Accessing the first row - You already have the 2D array in the loop, so not sure why you would want to pull the data from the listbox, as that's been formatted to 2 decimal places, so you'd lose accuracy.
Converting to a comma-delimited string - Use the Array to Spreadsheet String function. See attached pic for example.
Getting notified of this external value - This depends on what's generating this external value. You can use a queue, or a simple global.
Tip: You should separate the handling of the Stop button from the handling of the button to add a row. In your implementation if you click Stop you're forced to see the dialog to enter a value, even though you're trying to stop.
