Curious, but somehow shortening the library path solved the problem Alberto had: [WayBack] Hello Everybody, I have an application developed in XE2 (Hot Fix 2 + IDE Fix Pack installed) that has started giving me the “out of memory” error message… – Alberto Paganini – Google+:

It turned out the length of the library path was the culprit of the IDE out of memory error messages.
I have reduced the length of the library path and the error messages have reduced dramatically.
There are still a few out of memory messages tho.

There are six variations; only one can be active at a time:
- Delphi Office 2000 Servers Package
- Delphi Office XP Servers Package
- Delphi Office 2010 Servers Package
- C++Builder Office 2000 Servers Package
- C++Builder Office XP Servers Package
- C++Builder Office 2010 Servers Package
via: I cannot get MS Office sample automation server wrapper components. Neither of… [WayBack]

Just found some notes from 2013 for my research list that are still relevant:
Note that if you are using Smart Pointers, use the ones that Spring4D implemented in 2015 named Shared/IShared<T>/TShared<T>, see [WayBack] Spring4D – Pascal Today and [WayBack2] Smart Pointers will be in Spring4D 1.2.

When accessing the VCL from multiple threads at the same time: adopted from …\DEMOS\THREADS\THRDDEMO.DPR
Great question a while ago:
[WayBack] “Don’t access VCL from a background thread” – how to demo that? – Primož Gabrijelčič – Google+
For me, the ultimate way why not to access the VCL from a background thread is the precursor of the official threads demo that ships from Delphi 2 to Delphi XE6 in ...DEMOS\THREADS\THRDDEMO.DPR. where you’d think the thread isolation would be in ...DEMOS\THREADS\ThSort.pas but actually is in ...DEMOS\THREADS\SortThds.pas.
The first public showing of that demo did not include main thread protection. It originates from a session at the the 1995 Borland Developers Conference where Ray Konopka showed the below code from Bob Ainsbury.
That session reminded why this joke [WayBack] Via the EKON20 sessions… – Jeroen Wiert Pluimers – Google+ was so funny: “When Ray Konopka enters the room you have a Raize condition.“.
The question above also made me find back this reference to BorCon95 in San Diego:

While updating some old code fiddling with the[WayBack] GetThreadId function, I wanted to have some TThread wrapper around it. I had totally forgotten there has been already a means for this since Delphi 2009 (which initially had a bug, but that was worked around at first and fixed later): [WayBack] CurrentThread.
The latest version of Delphi, Delphi 2009, has a CurrentThread class property on the TThread class.
This will return the proper Delphi thread object if it’s a native thread. If the thread is an “alien” thread, i.e. created using some other mechanism or on a callback from a third party thread, then it will create a wrapper thread around the thread handle.
