Hi there, The most recent libraries I have for certain APIs are three C libraries; however, Delphi libraries are not offered. To work with apps, all libraries require DDL files; therefore, I need someone with expertise in Delphi to convert those libraries to native Delphi Pascal files. Many thanks in advance to all the specialists... CelikApi.h eVehicleRegistrationAPI.h eVehicleRegistrationCOM.h

Hello, Google Gemini (please don't even give it a try). ChatGPT 3.5: Correct Translation ChatGPT 4.0: Pro Translation Thanks to all the advice.

Hello developers, I have one function which is working fine until Delphi 12 but now I get Integer Overflow Exception procedure CalculateErrorCorrection(dest: integer); var A: TInt; ALength, e, k, t1, t2, t3, LastE: Int64; begin if (errorLevel < 0) or (errorLevel > 8) then errorLevel := 0; A := TInt(ERROR_LEVEL[errorLevel]); Alength := 2 shl errorLevel; for k := 0 to Alength - 1 do codewords[dest + k] := 0; lastE := Alength - 1; for k := 0 to lenCodewords - 1 do begin t1 := codewords[k] + codewords[dest]; for e := 0 to LastE do begin t2 := (t1 * A[lastE - e]) mod _MOD; t3 := _MOD - t2; if e = LastE then codewords[dest + e] := t3 mod _MOD else codewords[dest + e] := ((codewords[dest + e + 1]) + t3) mod _MOD; end; end; for k := 0 to Alength - 1 do codewords[dest + k] := (_MOD - codewords[dest + k]) mod _MOD; end; it fail at line: t2 := (t1 * A[lastE - e]) mod _MOD; every params were integer I change to Int64 but same error is there. Thanks for the any help in advance...

Hello, I have a lot of problems with different FormatSetting and Delphi apps; most of them are using dot on numeric keyboards and at the dot at the end of datetime, and I have small problems with the thousand separator. Does Delphi support some kind of isolated Format Settings where I can set my custom Date, Time, DateTime, Decima, Thusand separator, and so. on? In this scenario, the user can set isolated settings for the app, no matter how Windows works, and the user can use, for example, the pain problem. (dot) on a numeric keyboard. Now that I have dbEdit connected to FloatField and the user input is 123.45, it converts to 12345.00. Another problem is 123,345.67. I get invalid floatpoint values. Thanks for any advice and information in advance.

Hello Developers, Is it possible to extend the standard VCL component with some features (properties) without creating a new component? For example, I need to add two string properties to the CheckBox component (for auto-saving in an inifile, I need two value properties and a group name), and I think about a new VCL. Does someone have a better idea? Thanks in advance...

Hello, It is just like when I develop my config form, the CheckBox Hint is used for ItemName (because of the multiple same names in the config form), and the parent component name represents the ItemScetion, so this is my scenario now. But it is not only check boxes; there are also edit components (text, number, color, date, time, folder name, etc.). This is the main reason why I need some modifications to the base class to make some maintainable code.🙂 I have a lot of cases in my apps with this, but for some cases, like DataSet, I need to create my class or component because I need at least 10 properties to add to make my development process simpler. Thanks anyway; any comment is useful in some way.

Hello, Thanks for the reply. Here is a closer explanation of one of my ideas. I have a config form with a lot of checkboxes, which holds data in an ini file. The ini file has sections and values. So, I have a standard checkbox with two additional properties: one is IniSection, and the other is IniProperty OK. I would like to solve this without new components, but I need to keep this scenario: when I call save or load config dara method and I search iniFile by those 2 new properties from the checkbox,. I think that now it is a little bit clearer what I want to do with my additional properties. Thanks again for all the ideas...

I think about migrating all of our projects to one universal database VCL solution. As I can see on this forum, FireDAC, there are some changes, one of which is not backward compatibility, and another small but painful change. I'm using UniDAC, and it is OK, but it looks like FireDAC has a lot of improvements from version to version. So, if someone has experience with this topic, please share your ideas, experiences, and real stories. P.S. One more question: where is the official FireDAC support forum or website?

First of all, thanks to all the experts. I have a few cases in which FireDAC has a solution (for example, Firebird Backup) that is not supported by UniDAC. In one of my projects, UniDAC is working, but FireDAC does backup, restore, upgrade, and small maintenance jobs on the Firebird Database. At the end of all, I plan to migrate all because I have full FireDAC with Delphi instead of paying for UniDAC as a separate product. When I read the MichaelIT post, I think that UniDAC is a better solution and has a better approach for the database part of the app in Delphi.

Hello,, I have one strange problem with FastMM 5 and software performance. I'm using Delphi 12 Pro + FastMM 5 (build a 32- or 64-bit app). Before FastMM, I had problems with memory release. Now, when I add FastMM 5, memory management is much better.😞 BUT!!! When FastMM 5 is part of my projects, I have users (30% of them) who report me UI blocks, and they need to wait a few seconds for the UI release to be available for entering data into VCL components. Few users report app crashes, and restarting is mandatory. I don't change or set anything in FastMM 5; everything is just as it is in the factory state from GitHUB. I need some advice for this problem and for FastMM 5 in general. Thank you for all your help and useful tips in advance...

Hello to all, As Tommi says, everything is working fine with Delphi 11.3 and the latest VCL release of all the components that I'm using. FastMM 5 was not a problem, and I am sorry for my misunderstanding of this great tool. Again, Tommi's idea is great. Wait for the new release to show its full power. Thanks to all of you again...

And just like that, back to latest D11.3 + Updates 🙂 I'll post here my test and deploy results.

There is v5.05 on official GitHUB Channel (release date is 25.06.2023 do you have some fresh info 🙂

Hello, I have Proxmox on Intel I7 13 Gen with 32 GB of RAM and NVMe's latest generation, and I plan to build 3 VMs from FirebirdSQL v4 servers. I have 20 db's per VM and 10–25 users per db, and I need some information on which FirebirdSQL architecture to use (Classic, Super Classic, Super) and some additional information or tips from experts about VM's about databases (and for servers, if there is any useful info). Thanks for all the tips in advance.

Hello, FirebirdSQL has a replacement in Delphi for the null value, and it is called NaN (non-numeric value). I can't prevent this situation, ID DB, so I need to check if my variable (Real type) and my DataSet field (TFloat type) are numeric or not (nil, null, nan, etc.). Thanks in advance...

My question on the Firebird Google Group is the same as if I threw it in a well without any reaction :-)

Hello, Because of middle tier technologies I need to use Windows Server (without desktop experience). So I only have "problem" which scenario is best performance/resource for FirebirdSQL v4 64 bit Windows... Thanks anyway for advice...

Hello Experts, I installed Delphi 12 and started to recompile all of my components from scratch (because I have a license for only full source code components). Now, I can see some strange situation: every time I have some TList descendant VCL with some items function in 64-bit variant, I get an error. Every item has an error because some property of the list component is not defined. In Delphi 11.3, which was my earlier Delphi version, everything is working fine. Is there any upgrade for which I raised this problem? P.S. In 32-bit varioant, everything is working fine. Thanks in advance for any help and assistance... Sample if (FXLSGridSelection[FXLSGridSelection.Count - 1].RangeType = rtCol) then begin FXLSGridSelection[FXLSGridSelection.Count - 1].Row2 := FXLSGridSelection[FXLSGridSelection.Count - 1].Row2 - 1; end; RangeType and Row1 or Row2 is not defined (in64bit) in 32bit is fine...

Hello, Does anyone use LZMA from System.Zip in Delphi 11 and 12? I try it, but I get an error that this type of compression is not supported. Zip := TZipFile.Create; try Zip.Open(db.zipFile, zmWrite); Zip.Add(db.fbkFile, ExtractFileName(db.fbkFile), TZipCompression.zcLZMA ); Zip.Close; except end; Zip.Free; Thanks in the advance...

Thanks to all supporters & friends, it is working fine now in 32bint/64bit.

Hello, What can be problem here, in 32bit everything works fine, but in 64 bit I have an error unit Threads; interface uses System.Win.Crtl, Winapi.Windows, LzmaTypes, System.Classes; type TCEvent = THandle; TCSemaphore = THandle; TCCriticalSection = TRTLCriticalSection; TCAutoResetEvent = TCEvent; TCThread = THandle; TThread_Func_Type = Pointer; function{$IFDEF UNDERSCOREIMPORTNAME}__beginthreadex{$ELSE}_beginthreadex{$ENDIF}(__security_attr: Pointer; __stksize: Cardinal; __start: TThread_Func_Type; __arg: Pointer; __create_flags: Cardinal; var __thread_id: Cardinal): Cardinal; cdecl; external msvcrt name '_beginthreadex'; implementation {$IFDEF Win32} {$L Win32\Threads.obj} {$ELSE} {$L Win64\Threads.o} {$ENDIF} end. Error is: [dcc64 Error] Threads.pas(23): E2003 Undeclared identifier: 'msvcrt' Thanks for the help and assistance in the advance...

I'll give it a try, but there are some errors in OBJ files for x64 architecture. If I do the job, I'll publish it on GitHub.

Hello Anders, I have an excellent solution for Delphi LZMA with extremely good compression and a very fast process, but it doesn't work under 64-bit environments. This is my component for LZMA: https://github.com/ccy/delphi-zip. and if someone can check the 64-bit setup, it will be great. Thanks to all in advance...

Hello, Remy Lebeau, I was made to typecast to Integer and NativeInt, and everything is working fine now. Your post was a little bit late, but I used this method that you described here. Thanks anyway for all the information...

Solved, thanks to Uwe 🙂
