How to create an array as long as wanted?

Hello again!

We missed your last answer! Sorry. We will check it out... wbut where do we see that "Num Rows" ? We have looked. It is in the property node, right? Best regards.

Hello!

Where can we find the NumRows property? Best regards.

Hello Ex-jobb,

here comes a 2nd picture to show the "magic" behind the frontpanel...
If you disable/hide the index control of an array, you are free (and also responsible) to set the correct number of elements you want to display. That's what I do in this user interface (and I also adapt the window size to the number of displayed elements).
Please read the chapter on property nodes as I suggested in a different thread.

Best regards,
GerdW

Yes. The list of properties in the property node is divided by seperators. The bottom group holds the properties relevant to the specific type of control. Since NumRows is only relevant for arrays, this is where it will be found.

Hello again 🙂

We do not want to use the multicolumn listbox. We want to use an array of boolean. But in the property node of the boolean array there is no "Num Rows". Must we use the multicolumn listbox ? Is there no way to define the number of rows dynamically in a boolean array? Best regards.

But we do not find any label with "NumRows" ?? This is strange... the labels at the bottom is LockBooltext. When one drag it out it comes many of these... what are we doing wrong?

When you create a property node from an array the property should appear as "Number of Rows" in the bottom group.
Which version of LV are you using?

Alright 🙂 We will read :-). It would be a lot better if one could read in our own language cause we are not that good in english 😞 but we will try 🙂 Thank you for your help. Best regards.

Hello tst!

We are using LV 7.1. At the bottom it is a lot of "LockBolText" and above them it is "Strings[4]", "Colors[4]", "BoolText". We can not see any NumRows? We rightclicked on the boolean array in the front panel and then did create property node. That is how to do? What are we doing wrong then...

The properties you're seeing are the boolean properties. What you've done is to click on one of the booleans instead of the array border. Either create the property node from the array terminal on the block diagram or click on the border of the array when you create the node.
