On one of the sites, when having some Delphi package registration issues, the standard measure was to delete the complete Package Cache subtree (like HKEY_CURRENT_USER\Software\Embarcadero\BDS\17.0\Package Cache).
Since there is so little information about it, it is on my list of things to eventually research.
Some links I already found, but had no time for to fully read:
Unrelated: You should not delete the folder C:\ProgramData\Package Cache\? – Super User, but matched my initial delphi registry “Package Cache” – Google Search.
Yup, I did it: I added an “Undocumented Delphi” category.

TL;DR
The examples in this post are specific for NUnit but, you can apply this pattern for safely running unit tests in parallel to any unit test framework that supports parallel execution.
To safely run tests in parallel, do the following:
- Mark your test fixtures with the
Parallelizable attribute and set the parallel scope to ParallelScope.All.
- Create a private class called
TestScope and implement IDisposable.
- Put all startup and clean-up logic inside the
TestScope constructor and .Dispose() method respectively.
- Wrap your test code in a
using (var scope = new TestScope) { ... } block
From [WayBack] Run your unit tests in parallel with NUnit, which also covers:
- Background (on why you might want this)
- How to safely run tests in parallel
- Maximizing parallel execution with Visual Studio
- Maximizing parallel execution with Azure DevOps

[WayBack] datetime – Determine Whether Two Date Ranges Overlap – Stack Overflow answer by Charles Bretana with input from and .
TL;DR (proof is in the post)
(StartA <= EndB) and (EndA >= StartB)
Alternative (also from the post):
DateRangesOverlap = max(StartA,StartB) < min(EndA,EndB)
It gets complicated when the date boundaries for A and B can be out of order.
The post also covers that.

Every once in a while you want to have a Delphi Watch of a field inside an object (say an object of type TContext), except that the field has no value yet, but eventually will point to another object (say an object of type TUser).
However, the original object will go out of scope, so you need to employ a few tricks.
First of all, you get the address of that field:
@(Context().FCurrentUser) = $7EF6F624
Then you watch the content of that field:
TUser(PPointer($7EF6F624)^),r = nil
To get to this trick, you have to remember:
- The contents of address
$7EF6F624 is pointer (at first nil) to a TUser.
- You get to the contents of the address
$7EF6F624 by using PPointer($7EF6F624)^.
- Then you cast it to the object you want with the
TUser(...) cast.

A cohesive and comprehensive walk-through of the most common and empirically useful RDP-related Windows Event Log Sources and ID’s, grouped by stage of occurrence (Connection, Authentication, Logon, Disconnect/Reconnect, Logoff).
…
Event ID: 25
Provider Name: Microsoft-Windows-TerminalServices-LocalSessionManager
Description: “Remote Desktop Services: Session reconnection succeeded:”
Notes: The user has reconnected to an RDP session, when the “Source Network Address” contains a remote IP address. A “Source Network Address” of “LOCAL” simply indicates a local session reconnection and does NOTindicate a remote RDP session reconnection. Note the “Source Network Address” for the source of the RDP connection. This is typically paired with an Event ID 40. Take note of the SessionID as a means of tracking/associating additional Event Log activity with this user’s RDP session.
TL;DR: The user has reconnected to an existing RDP session, so long as the “Source Network Address” is NOT “LOCAL”.
- [WayBack] Jeroen Pluimers on Twitter: “How can I run a script (batch or powershell) when a remote desktop connection starts? (either re-connects to an existing Windows logon session, or starts a new Windows logon session)? I know how to cover the last, but not the first.”
- [WayBack] CHUA Chee Wee on Twitter: “Watch Windows event log for RDP events. You’ll figure which one out, then execute a designated script.”
- [WayBack] Jeroen Pluimers on Twitter: “Thanks, found it: Log Name Microsoft-Windows-TerminalServices-LocalSessionManager/Operational Log Path %SystemRoot%\System32\Winevt\Logs\Microsoft-Windows-TerminalServices-LocalSessionManager%4Operational.evtx EventID 25 Now I need to find how to initiate a script on this.”
- [WayBack] CHUA Chee Wee on Twitter: “Manually, it’s within eventvwr, click on the event and right click, select attach task to this event. Programmatically, you’ll need to figure out the equivalent.”
- [WayBack] Jeroen Pluimers on Twitter: “Thanks. In the mean time I was collecting some links for a blog post about this which includes blogs.technet.microsoft.com/wincat/… That’s a more elaborate version of what you describe, so both of these will get me going.”
