Starting with Delphi 12 they are disabled by default. What's New - RAD Studio - Disabling Floating-Point Exceptions on All Platforms

That has always annoyed me - step one of looking for products/solutions is to survey what is out there and compile a list with basic information. I usually just ignore/skip anything where the information is hard to come by as I have been burned too many times. Far too many companies' think their product is good for X when feature wise that would be true, but price or licensing terms make it not. I want to know that from the start not after wasting hours evaluating a product and dealing with sales calls. Most of the time 'contact sales' means the product has runtime fees, weird tiered pricing or terms making it unsuitable for a lot of scenarios.

Could free the forms instead of hiding. Has other issues like losing state but they can be overcome. Adding saving/loading form state is useful between program runs as well so work can be resumed quicker. MDIIssue2.zip

MySQL can only have one running/open query per connection. What you are seeing is normal for MySQL.

There is not one executable format but two: ARM64 and ARM64EC (ARM64X PE files) on Windows 11 ARM64. The latter makes moving to ARM incrementally easier but does complicate things for third party compiler makers like Embarcadero. Bit a shit show from Microsoft over the last decade - first Windows on ARM had a new API only, then Win32 / x86 emulation and now finally a way to mix x86 and specially built ARM binaries. I think ARM will fall behind as a platform because it is fragmented and siloed. Remember how M68000 got beat by x86 - thanks to DOS and then Windows becoming a widely used platform x86 got an order of magnitude more $$$ invested into the platform. ARM just doesn't have the $$$ getting invested into platform improvements that x86 does and some of the improvements don't go to all users - like x86 emulation help on Apple M1 CPUs not available elsewhere. Contrast that to AMD's Ryzen/EPYC all using the same CPU tiles - the improvements from investment hit everything from Valve Steam Deck handhelds, Threadripper PRO workstations and the FRONTIER supercomputer.

Results/matches are produced linearly so ForEach() has nothing to work on. You could use tasks to do the work on each match. (4. Low-level multi-threading (omnithreadlibrary.com))

Consider when code using unmasked exceptions calls code in a DLL that uses masked exceptions. The floating-point control register (FPCR) needs to be set to mask exceptions just before the call then unmask them on return. The functions provided by Delphi to update the FPCR are not thread safe so they can botch it. For the non-FMX Windows platform Delphi code ran with unmasked floating-point exceptions on by default before the recent change. Most C/C++/C# code runs with them masked. This meant the above scenario happened when calling into most non-Delphi DLLs from Delphi.

I started with FlashFiler then migrated to NexusDB for both standalone and C/S versions of applications. The former was available years before SQLite came on the scene and the latter was the spiritual successor of the former. Never migrated to SQLite because using C/S tooling during development of even a standalone application makes things easier. Both a database development tool like Upscene Production's Database Workbench and the application itself can access the live database tables at the same time easing debugging and other tasks. Can then ship the application with the same database engine compiled into the EXE but hooked up directly instead of through C/S components. Originally used FlashFiler as the database engine for an application + database published monthly on a CDROM. With some modifications to the source to open read-only files as shared it worked well for years. Both FlashFiler and NexusDB are royalty free so no per user fees in either standalone or C/S configurations.

Take a look at the Windows Sandbox, a feature available in Pro and higher of Windows 10 and 11. It provides a clean Windows environment and uses RDP behind the scenes. Useful for catching some RDP issues and missing dependencies/requirements etc. Ref: Windows Sandbo| Microsoft Learn

From an organizational perspective a web server like IIS is easier to manage, especially in the long term, than individual web services running on random machines and ports. System administrators are familiar with the logging and configuration of a web server and can perform various tasks without involving the developers. For example, keeping https settings up to date by disabling weak protocols and cyphers. You don't need a web server, but it might be beneficial to consider using one.

With any substantial number and sizes of files that could waste a lot of time as the whole operation keeps being restarted after each problem is encountered and fixed. I would suggest doing the copy with a tool that synchronizes directories then once everything is copied successfully delete from the source. Can even use the same tool for both steps - like robocopy to copy everything followed by a /MOVE pass to pick up any last minute changes while clearing out the source.

Can also use the command line utility certutil. Supports calculating MD2 MD4 MD5 SHA1 SHA256 SHA384 and SHA512 hashes. certutil -hashfile <file> <algorithm>

Been a while but I remember disabling some packages to speed IDE startup. Certainly, a welcome page listing the latest updates for an IDE that hasn't gotten updates in years is a waste of time to load with the IDE. Often used the instructions at: Delphi packages I have disabled by prefixing their description with an underscore (and why) « The Wiert Corner – irregular stream of stuff

I found that annoying as well. For several years I would set the debug desktop to the regular desktop and turn off hide designers on run. Made compile/run/test cycles much faster. I usually did not need the debug panels as most testing was in the application being developed. No longer needed with very recent versions as IDE redrawing is better so switching desktops and hiding/unhiding designers is fast.
