Rif.: Dynamically append 2D array to Multicolumn ListBox

[SolPS]

Here you go inspector!,.. I'd like to see what you have in mind...

Sorry, I have no idea what this is supposed to do.

• You have a cluster that never changes and that only gets defined if the outer case is false. If the VI is run first with write=true, all cluster values will be zero until the first time the write=false case executes. Since it never changes, maybe it should not even be in a shift register, but just a diagram constant.
• It this is supposed to be an action engine, why are none of the connectors assigned?
• Cases 1, 2, 3 only differ by the unbundle. Why triplicate all that other code?
• Can you explain in simple words what the VI should do based on input. What are possible inputs (# of rows, values, etc.)
• What should happen if the first row element is not 1, 2, or 3?
• What is the max size of the input and output arrays?
• Is the number of rows fixed for each group number, but can differ for different groups?
• so. many. questions.

[altenbach · Accepted solution]

Assuming each group has a fixed number of rows as defined in the diagram constant (8,6,6 here), here's what you could do.

Since we use a globally initialized feedback node, this will need to be called from a running toplevel. Example included.

Thanks Altenbach. The code you attached was very helpful. Much appreciated!
