Array size from reference

[Mellberg]

Hello!

Is there any possibility to get the size of an array from a reference to the array?

Since the data type within the array is unknown, I can't convert it to the actual data type and then use the built in 'array size'.

Thanks in advance!

What is an Array? (see next)

Shaun's answer provides the number of visible elements for an Array control.

However you could get the 'Value' of the array control, that would return a Variant with the OpenG function Array Size(s) the actual size of the data stored in the control:

Thanks Ton, looks like what I was looking for!

Please not that this is not exactly a cheap way of determining an array size. The value extraction will create a copy of the array, potentially using quite some memory and also costing performance to do the copy. No problem if your array contains only a few 100 elements but definitely something to think of with an array that could contain 1 million values.
