Thanks Uwe for the below code!
I was in a situation of a batch file running from a Task Scheduler that got broken because the user suddenly turned on persistent network connections.
So I needed to check if a shared drive-letter was indeed persistent or not and act accordingly.
The below code helped me merging the batch file with the Delphi application it would run in the background anyway.
It’s way better than checking of the global “persistence” flag for new connections has been set in the registry: [WayBack] SaveConnections flag at HKCU\Software\Microsoft\Windows NT\CurrentVersion\Network\Persistent Connections (which is reflected both in the Windows UI and settable via net use /Persistent).
Source: check if network connection is permanent
Via: [WayBack] Anyone who can share how one can query if a drive letter mapping to a share is persistent across logon sessions? (yes, this is Windows, I know) – Jeroen Wiert Pluimers – Google+

A post of some older Delphi stuff I did in the past just in case need it again.
David Heffernan found the documentation for this: [WayBack] Structured Types (Delphi): Dynamic Arrays – RAD Studio
Since I needed a dynamic array structure supporting a non-zero lower bound, I was glad he also provided an answer with a data structure that does provide a non-zero lower bound.
For my own reference I’ve put his answers and questions below (as it’s way easier to search my blog than the complete internet) and my own implementation:

Via [WayBack] Scott Hanselman @shanselman: Excellent blog post from Jessica on how to setup the best Linux on Windows environment! @jldeen:
[WayBack] Badass Terminal: FCU WSL Edition (oh-my-zsh, powerlevel9k, tmux, and more!)
It’s that time again! The time to write another epic blog post, this time for WSL, also known as Windows Subsystem for Linux.
It requires Windows 10 Version 1709 (Fall_Creators_Update) which has build number 10.0.16299.

An era ends: [Archive.is] CompuServe’s forums, which still exist, are finally shutting down
Before there was a World Wide Web, a sizable chunk of all meaningful conversation between computer users happened in the forums at CompuServe, which was the dominant online service until AOL came along. There was a CompuServe forum for everything from PC hardware to comic books, the signal-to-noise ratio was generally high, and … they if you … will be removed from what remains of CompuServe on December 15.
I remember spending a truckload of money on 100013,1443. Heck: it was the reason for getting a credit card in the first place!

The first trick works for WinBox 3.7 on Mac [download], the second doesn’t.
First trick:
To override your security settings and open the app anyway:
In the Finder, locate the app you want to open.
Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.
Press the Control key and click the app icon, then choose Open from the shortcut menu.
Click Open.
The app is saved as an exception to your security settings, and you can open it in the future by double-clicking it just as you can any registered app.
Second trick:
Note: Another way to grant an exception for a blocked app is to click the “Open Anyway” button on the Security pane of System Preferences. This button is available for about an hour after you try to open the app.To open this pane, choose Apple menu > System Preferences, then click Security & Privacy.
