For [RSP-42049] IDE Freezes - Embarcadero Technologies I see nothing but the description so not enough to do anything since they can't reproduce the error both to see what is happening and to verify any solution.

The IDE loads designtime packages along with runtime packages before it makes instances of components for the visual form designer. It doesn't do that when compiling. Making sure third party components are installed, reinstalled or updated after installing a new Delphi can help make sure everything is all hooked up and working so they load into the IDE and work without issues in projects that use them. Not sure what the underlying issue is just that I have seen similar errors and re-installing third party components solved it. Guessing it fails to load something but ends up showing an out of bounds error for some reason.

Sometimes see this error if third party components are not installed and up to date. For example updating to a new Delphi release but not updating third party components like FastReports but just using what was already installed.

A common issue is network paths that are no longer valid. The IDE often tries to access such paths multiple times and doesn't handle waiting on the network timeout very well (it tends to freeze while waiting). If the server name in the path resolves but there is never any response the network timeout can be 10-30 seconds or more each time it tries to access the path. The freeze happening after you do some typing suggest code completion / IDE insight is scanning source paths and one or more of them are not accessible. Systinternals has some utilities like Process Monitor that might help in showing what the IDE is trying to access when the freeze happens.

Scoring using the most common words for each language works surprisingly well. Even scoring each line using the 50-100 most common words works most of the time except for very short lines or odd fragments of longer sentences. If the scores are close for different languages a more complex approach can be used for that line. Would work better if you can group lines together in paragraphs or sentences so very short lines would be less of an issue. Even just the 10 most common words works for longer text and a lot of short text English : the be to of and a in that have I French: être avoir je de ne pas le la tu vous German: wie ich seine dass er war für auf sind mit

Could try overloads of a procedure. From the calling site it does what you want but requires a separate definition for each combination of argument types / number of arguments. Procedures and Functions - Overloading (Delphi) - RAD Studio (embarcadero.com) Added: Looks like not much use here due to not being able to easily get a reference to the property as a property vs as a value.

The help also says it is generated if either option is set (detailed map files OR .drc generation); Package Files Created by Compiling - RAD Studio (embarcadero.com)

Can try the various SysInternals tools (Process Monitor and Process Explorer) to see some of what that app is doing. There is also tools like API Monitor to see what Windows API calls (and results) the application is making, Depending on the database and database connection method there are logging tools there as well. Sysinternals Process Utilities - Sysinternals | Microsoft Learn API Monitor: Spy on API Calls and COM Interfaces (Freeware 32-bit and 64-bit Versions!) | rohitab.com A long shot would be checking any code that runs during shutdown for IF's that might be coded wrong for 64bit so try to do things they shouldn't like try and open a database connection to a non-existent database server.

Myself I would use the file system over SQLite. Store extra information with the images as either image metadata or in a file beside the image file. This lets you regenerate the database from the files as needed. Less involved to do incremental backups. A small SQLite database file + changed image files vs a large SQLite database file with images in it.

Without the error(s) and what you tried it is hard to answer. Would suggest reviewing : Bluetooth permissions | Android Developers to start since you mention permissions issues.

It shouldn't be the issue in general as they even have an option to optimize for Windows on ARM so they at least test on that platform. Still wouldn't hurt to try the application without protection to see if the error message is more helpful. The 0xc0000409 suggests a missing or corrupt library / resource / etc which can be something required by something you load making it harder to track down. Optimize for Windows on ARM: The Windows on ARM emulation produces some penalties when emulating specific code or data accesses. This option produces a protection code that is emulated faster on Windows on ARM with just a small reduction in complexity in the protection code.

There are a fair number of Delphi grids still in active development. One is Developer Express : VCL Data Grid. It is expensive but has a lot of features and is the one I use. It has a provider mode where it basically handles querying the database for you when doing sorting / filtering in the grid itself which works much better on larger datasets than the more common pull all data locally (which it also supports). It has a bit of learning curve but once figured out you get a lot functionality with little or no code. VCL DataGrid - High Performance Grid for Delphi & C++Builder (devexpress.com) Read question too fast. It does not support FMX. They tested the water with FMX but seems there was not enough demand from their current customers to make it viable.

I also think Delphi should transition to a 64 bit IDE so it works better with large projects. As well with high entropy ASLR it could make it easier to find memory bugs in the IDE/plugins/design time components as most addresses would be invalid vs valid when the IDE uses a lot of memory. The breaking change of the IDE not running on 32 bit operating systems is a non-issue at this point. I have no problem with components living / running in the IDE. Perhaps Embarcadero could pay to get a component development guide updated or written along with some helpful tooling / debugging support to help revive wider 3rd party component production.

With DLL injection it could be anything. Can use something like Sysinternals Process Explorer to see what DLLs are loaded in a process and compare between the two systems. Process Explorer - Sysinternals | Microsoft Learn

Windows 11 did change the default font to Segoe UI variable which is supposed to scale better on High-DPI displays than Segoe UI (Vista onward). It changes how some characters look including how tall they are which could lead to some UI issues.

Find out where the performance is being lost. Dynamically creating a form instance and it's content like that should be quick. I could see it being slow if it was incrementally built in a way that causes endless events for things like resizing, drawing, layout and themes or something else causing cascading methods/events/etc that could be cleaned up.

The IDE certainly scans the various library path directories a lot and when it does so the performance probably tanks with a Parallels shared home directory vs a real directory. Same thing happens for invalid paths - the IDE spends a lot of time waiting / working to the point it feels like it has locked up. This applies to a lot of virtual / network / shared directories that end up having a lot of access calls - they will perform very poorly compared to local files on a native file system.

Outside a set $ matches a position not a character and within a set it matches the character $. One option is to use a capture group with |. So this pattern: \d+-\d+(\s|$)

See this most often when ASCII is automatically cleaned up typographically for printing by doing some conversions like dash to em dash. If this text is put back / interpreted as ASCII bytes the various UTF8 encodings of the typographical replacements end up us multiple characters each like a minus/dash that was converted to em dash then ending up as †". Need to find where the problem is - the data in the PDF itself could already be corrupted this way or it can happen at some other stage including in the PDF -> Text or in how you load the text. Often even if you do interpret the encodings correctly so there is a — (em dash) instead of †" the equivalent replacements might be worthwhile to convert text back to plain ASCII.

Private repo or something you made in your sleep and haven't realized isn't real (yet!)? I can't be the only one who sometimes dreams of writing code and latter wonders where it went.

What database? Some databases have UNPIVOT to more easily convert columns to rows (the reverse of PIVOT which converts rows to columns).

I worry about the maintenance of applications using some of these cloud services. Sourcing a replacement library/component/backend between major releases or updates is a walk in the park compared to having to replace a cloud service possibly live or at least on the cloud service provider's schedule vs your own.

By default the IDE keeps a history of saves. What is showing up there? (bottom right of edit: History. should list revision contexts including file, buffer and any history files). I know sometimes the same file accessed with different paths in different editors can end up with issues.

The libmysqlclient.dylib file is included with the MySQL server install in the lib directory.

Get another developer to clone/copy one of your projects and try working on it. Have them copy / duplicate NOTHING of your system/network/software/development configuration. Something sounds off with your system/configuration/network/etc. Long IDE freezes can be as simple as dead paths being searched - Windows can take a long time to timeout checking a network drive where the other side doesn't respond at all for example and Delphi tends to re-search the same paths often making it take even longer. The worst would be an intermittently accessible path / storage location which would cause all sorts of hard to discern problems. Even bad sleep/resume of a storage device can cause problems or delays. For all the internal errors - if they happen reliably you might be able to narrow it down to small test case(s) - they usually do get fixed if there is a reliable way to reproduce both so they can see the error and test a fix.
