Is there any way a user can view or copy non-editable GUI controls' contents at runtime?

Solution 1:

1. I have generally had success with Snagit's Text Capture feature that supports:

   Window          Region              Scrolling Window
   Active Window   Fixed Region        Scrolling Active Window
   Full Screen     Object              Clipboard Rich
   All-in-One      Custom Scroll       Text Formatting
   

2. There's also HyperSnap's similar TextSnap feature which I have used successfully.

3. AutoIt's Window Information Tool AU3Info may very well be able to help:

   

4. There's also CopyText but I've never tried it:

   

Solution 2:

There is Property Edit, but I'm not sure if it will help in this particular example; it actually looks like the string is trimmed before displaying.
