Re: New user
Welcome to the list, Alex! There are people here who are a LOT more familiar with Windows <-> device communication than I am, but I can at least ask questions. Are you familiar with the "open driver" command and "serialControlString" property? They might give you some of what you need. I confess I haven't worked in a Windows environment in many years, so what I used to know may now be obsolete. Ahh, technology!

Re: Record audio on Mac
Yes and despite info to the contrary mergMicrophone does still work in a standalone on macOS, but as a “heads up”, entitlements may be an issue making a standalone that uses it because on newer macOS need user permission to use the microphone. I entirely removed the signature on a standalone and then it asked for pets mission as required.

Re: How to get a hilitedElement value from a Tree View's arrayData?
I’m using the Tree View widget to provide a quick and dirty read-only display of the various arrays of information that can be extracted from the PDF Widget. Each PDF page contains too much text to read & understand within the constraints of a single line in a Tree View control. So, on highlighting an element in the Tree View, I want to display its value - such as arrayData[“Pages”][“1”][“text”] - into a field to read the detail extracted. (Currently I’m putting it into the message box as an interim step, as I tend to build & debug my scripts line by line and this is as far as I’ve got!) I may have misread the docs but it seems that when a Tree View element is hilited, one doesn’t get immediate access to the element’s value. Instead, one has to jump through hoops, by handling the hilitedElement, which returns the nested keys of the element. So, I’m simply trying to convert this comma-separated list to an array reference, so that I can get the value associated with this key. If I’ve missed a simple means to access the Tree View element’s value directly ‘on click', I’ll gladly change course! Best, Keith > On 20 Dec 2021, at 20:46, J.

Re: How to get a hilitedElement value from a Tree View's arrayData?
I'm confused about what the goal is. The hilitedElement contains the text of the selection. The array is already in place, so you don't really need to add to it. The reason you're seeing text in the message box is because the last line contains an unspecified "put". Without a destination for the "put" it will go automatically to the message box. If you want to work with it, you'd need to put the value into a variable. What's the purpose of the concatenation, and what do you want to do with the selection?

How to get a hilitedElement value from a Tree View's arrayData?
Hi folks, I’m struggling to access the value from a Tree View widget’s data array as the hilitedElement changes - though I think my issue is more about working with arrays than the Tree View widget. The following test script (on the Tree widget) successfully gets the Tree’s arrayData into tTreeData and creates a ‘correct-looking’ nested array key syntax for any changing tHilitedElement. However, the last line displays the tHilitedElement variable string in the message box rather than concatenating it to tTreeData as the nested key to return the element’s value. on hiliteChanged put the hilitedElement of me into tHilitedElement if char -1 of tHilitedElement is comma then delete char -1 of tHilitedElement replace comma with quote & "][" & quote in tHilitedElement put "[" & quote before tHilitedElement put quote & "]" after tHilitedElement put the arrayData of me into tTreeData put tTreeData & tHilitedElement end hiliteChanged I’ve tried various forms of brackets around the tHilitedElement variable containing the nested key string with no success - what am I doing wrong?
