Im just getting into using LabView and I ran into an error I can't seem to get rid of while working on a small sample exercise with the Bundle by Name Function.
Under here you can find my front panel, block diagram & error message displayed.
The output cluster is all indicators and all the items in the Enums have the same values, I don't know what I am doing wrong here. Can anyone help out?..
Thanks in advance!
Just delete your output cluster, than right click on bundle function and create indicator.
The problem is your output cluster order is other than cluster constant order.
Please read about type definitions and consider using them to avoid problems like this in the future.
Double check that your indicator and the cluster constant are actually the same type. A short cut would be to delete the existing control and just creat a new on by right clicking on the terminal of the unbundle by name and selecting create>>indicator.
Given the error message, I would say that it's because of the difference in elements order, between the constant you're giving to the Bundle, and the indicator wired to the output.
You can make sure of order consistency by right-clicking on the border of the cluster constant, and select AutoSizing -> Arrange vertically. This will order the elements, and to fix it you re-order by selecting Reorder controls in cluster in the same menu. Of course, you can also fix the ordering of the indicator.

I am building up composite layups and assigning them to element sets. When I do so as soon as I try to submit the job, Abaqus always gives me the error "The following parts have some elements without any section assigned". There is not a single element without a material property, I do this by a script. As soon as I use a set which does not contain elements but a geometry Abaqus highlights the region green, but using geometry instead of element sets is not very suitable for me, because I am changing the properties of different elements. Also the region selection window opened by abaqus says "Sets below may contain elements, cells, shell faces or wire edges", so it should be possible to use element sets right?
I use the section assignment only for a small amount of elements, everything else is covered by composite layups.
If needed I can share more details from my model, but as I am not sure where to look for any errors right now, I wont do that right now.
Best regards and thanks for any advice!
You can do data check and then in open generated odb in viewer. In opened odb you can find ErrElemMissingSection in 'Display groups'
I've tried nearly anything, The "Type Into" activity won't print plain text into the text box let alone a held variable. The textbox element in question is the update work items comment box in the acme-test website from the Level 3 RPA developer course. I am able to type into the box manually and the robot is able to find it (the cursor moves to the centre of the text box and the program continues). I've tried quite a lot, including using a click activity and then sending the string as hotkeys.
Most probably the issue is related to your selectors. Since you are on level 3 RPA developer course I assume you are using Reframework for the task and I believe because of comprehensive error handling capabilities of this template your application just continuous with the next item instead of crashing when it can't find the element.
To solve the selector issues I usually do the following:
Use partial selectors instead of full selectors
Use wildcards for dynamic parts of your selectors (* for replacing any number of characters, ? for replacing exactly 1 character)
You can also store the page you are working on in a Uipath.Core.Browser type variable to eliminate the need of reselecting browser.
Also keep in mind that if you have used basic recorder functionality of UI path it generates full selectors.
I am making an applocation to demonstrate some algorithms, and I am using gtk2hs. When the user selects an algorithm, I want the whole window to change (different layout, input, output interface...). How could I do that? For example, is it possible to change the widget in a container? I tried a table but could not changed the content of a cell, so that doesn't seem like a good idea.
Also I want to change the number of input fields according to another input field, and that seems like the same problem for me (removing widgets from a box) but it might be totally different in terms of solution.
Thanks
How to change the content of a box, can you delete a widget from it? If yes, how?
Use widgetDestroy. See for example this tutorial.
I want to display multiple SubVIs (each one has a set frontpanel with controls and indicators) in my main VI. The problem is: usually only 2 or 3 are active at the same time, the rest are deactivated.
Let's say I got an array of VI references for the active SubVIs. Is it possible to display the SubVIs in a table, where each SubVI gets its own row?
I'm basically looking for a container similar to a Tab Control, but instead of tabs I want to display the VIs row-wise.
Thanks in advance.
The best choice for you is sub panels. http://digital.ni.com/public.nsf/allkb/D587067E18E0E70186256D44007B91FE

Also there is nice way with xcontrols, but it is complicated and takes more time to implement. Anyway below is link about xcontrols:

I was unable to place a Sub Panel (which shows a VI's front panel) in an array control, but I was able to place it and its VI reference in a cluster, and then place that in an array:
After that, you could set the VI Ref's visibility to hidden, and tweak the array's chrome. Going further, I don't know if LabVIEW provides a way to give that subpanel a VI reference when it's in a container, so your mileage may vary.
Following on from a question I posted yesterday about GUIs, I have another problem I've been working with. This question related to calculating the bending moment on a beam under different loading conditions.
On the GUI I have developed so far, I have a number of sliders (which now work properly) and a pop-up menu which defines the load case. I would like to be able to select the load case from the pop-up menu and position the loads as appropriate, in order to define each load case in turn. The output that I need is an array defining the load case number (the rows) and a number of loading parameters (the itensity and position of the loads, which are controlled by the sliders).
The problem I am having is that I can produce this array (of the size I need) and define the loading for one load case (by selecting the pop-up menu) using the sliders, but when I change the popup menu again, the array only keeps the loading for the load case selected by the pop-up menu.
Can anyone suggest an approach I can take with (specifically to store the variables from each load case) or an example that illustrates a similar solution to the problem?
The probem may be a bit vague, so please let me know if anything needs clearing up.
Many Thanks,
James
You could use Application Data to store the current loading case and have a application data structure to store the values of each slider for the different loading cases.
In short, you could use the setappdata and getappdata to save and load the data you need. Mathworks has more information here.
