Sorry, not yet. I didn't dare: You would all point a finger at me and laugh at the program code. 😉

What I did to get my favorite color scheme from 10.3 to 10.4 and have it stick. In 10.4, go to Options | User Interface | Editor | Color With the current colors, just click on [Save As] and and give your personal scheme a name. I called mine Lars. This creates a Registry branch, named HKEY_CURRENT_USER\Software\Embarcadero\BDS\21.0\Editor\Highlight\Custom themes\Lars In RegEdit, go to HKEY_CURRENT_USER\Software\Embarcadero\BDS\20.0\Editor\Highlight (i.e. the Rio branch) Export to a file, f.x. MyColors.reg In MyColors.reg, you'll see Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Embarcadero\BDS\20.0\Editor\Highlight] [HKEY_CURRENT_USER\Software\Embarcadero\BDS\20.0\Editor\Highlight\Additional search match highlight] ... and so on Now, Open MyColors.reg in Notepad, search for "20.0\Editor\Highlight\" and replace it with "21.0\Editor\Highlight\Custom themes\Lars\". Add the two branch paths for good measure. Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Embarcadero\BDS\21.0\Editor\Highlight] [HKEY_CURRENT_USER\Software\Embarcadero\BDS\21.0\Editor\Highlight\Custom themes] [HKEY_CURRENT_USER\Software\Embarcadero\BDS\21.0\Editor\Highlight\Custom themes\Lars] [HKEY_CURRENT_USER\Software\Embarcadero\BDS\21.0\Editor\Highlight\Custom themes\Lars\Additional search match highlight] ... and so on Import the file into the registry, Restart the 10.4, go to Options | User Interface | Editor | Color and pick the custom theme "Lars".

There are always at least three fingers pointing back...so, no worries. I'm laughing at my own code at a regular basis...and crying...drinking even. Oh dear.

Hey, give us something to laugh! Would make for a nice change for me right now.

Please go fight in private and stop killing this great thread.

This is a known bug, when exiting Delphi 10.3.n Rio or Delphi 10.4 GExperts creates an error. EAccessViolation in module rtl270.bpl ... in module bds.exe Followed by another one : Exception EAssertionFailed in module GExpertsRS104.dll at ... Call DeactivateFontInfo before calling this. ....SynTextDrawer.pas line 475 Since I'm installing Sydney 10.4 I realized (thanks to my VM Snapshots) that GEpxerts behaves perfectly until I install TMS FixInsight. If I take FixInsight out, then the problem is gone. That may be one lead to follow. I have many TMS Components that coexist without problem with GExperts. It seems to appear only once FixInsight is installed. Some users may have that SynTextDrawer error too without this component, but you never know. Just my two cents

This was my plan all along, I just did not see the "Custom themes" subkey 🙂 Thank you, @Lars Fosdal; this method works like a charm!

This might be a bug, then. I just found one similar to what you are describing IDE does not remember user color seting for source editor https://quality.embarcadero.com/browse/RSP-28754

Yepp, I know why 😄 The original Welcome Page was designed by me during the field test, and at that time "wuppdi" was the "thing" at the German Delphi Praxis, and I wanted to include that somehow and that's how it ended up there 😄 wuppdi is a simple CSS class to hide different things. doShow CSS class was used to override wuppdi 😄

If the term pebcak is offending you must be new to the internet. I simply explained the way that always works for installing jcl/jvcl 1. The same as always - jcl\lib\d27\win32 or win64 and jcl\source\include 2. Yes, works JCL/JVCL setup issues are almost always a problem with not properly executing them or rather not having the latest jcl/jvcl sources or having some old stuff lying around. Maybe you did not update the submodule and are missing on the defines for 10.4 Also did you select both (10.4 32bit and 10.4 64bit)? And did not set the "Install selected only" checkbox?

Clearly a pebcak. Just pulled the jcl repo, ran install.bat - it compiled the setup using 10.4 and then I installed JCL for 10.4 32bit and 64bit without a problem

If you crash your drive with a hammer, you would also loose all your data. The SQLite3 reference article is really paranoid, and its default settings are aircraft-level secure. If you have exclusive access to the SQLite3 DB, then most of the database corruption problems disappear. To be fair, 'entreprise' DBs don't synch to disk at every transaction. I have had Oracle databases not able to mount at all after a power failure. Whereas SQLite3 may loose some data, but can almost always reopen its SQLite3 file. We used those settings on production DB since years with TB of processing data and billions of insert/select, with no data loss (only journalmode was left to its default). The OP was talking about mobile app, where I doubt such paranoia is required.

OmniThreadLibrary 3.07.8 has just been released. It contains few small fixes + support for Delphi 10.4 Sydney. Changelog: New features: Implemented IOmniTask.RegisterWaitObject with an anonymous method callback. [Jacek Laskowski] donated a new OTL icon (res\OTL.ico). Added Delphi 10.4 Syndey packages. Bug fixes: [sglienke] A reference to an anonymous method executor in IOmniTask is cleaned up as soon as possible. This allows OTL tasks to be executed from a package. [issue #132] TOmniMREW.TryEnterReadLock and .TryEnterWriteLock were returning True on timeout. SetOnMessage(nil) works correctly. Fixed invalid FreeAndNil of an interface in TOmniFuture<T>.Execute. Compiles with Delphi 10.4 Sydney. https://github.com/gabr42/OmniThreadLibrary/releases/tag/release-3.07.8

I have just write a little command line utility to convert your ANSI file to UTF-8. https://github.com/Kryuski/AnsiToUtf8
