I have just put a simple question on ChatGP 4o : What is the best programing language for database applications Answer The "best" programming language for database applications depends on what kind of database app you're building—like web-based, desktop, real-time, embedded, or enterprise-scale—and what tech stack or ecosystem you're working within. But here are some of the top contenders, with reasons why they might be the best for different cases: Top Languages for Database Applications 1. Python Why: Simplicity, huge ecosystem (SQLAlchemy, Django ORM, Pandas), rapid development. Use cases: Web apps, data analysis tools, automation, scripts, dashboards. Databases: MySQL, PostgreSQL, SQLite, MongoDB, etc. 2. Java Why: Mature ecosystem, JDBC, widely used in enterprise apps. Use cases: Banking systems, enterprise software, Android apps. Databases: Oracle DB, PostgreSQL, MySQL, SQL Server. 3. C# (.NET) Why: Tight integration with Microsoft SQL Server, powerful for Windows and enterprise apps. Use cases: Desktop apps, enterprise solutions, Windows-based tools. Databases: SQL Server, SQLite, PostgreSQL. 4. JavaScript / Node.js Why: Async handling, great for real-time and web-based DB apps. Use cases: Web apps, real-time dashboards, APIs. Databases: MongoDB, PostgreSQL, MySQL (via Sequelize, Prisma, etc.). 5. SQL (and PL/SQL / T-SQL) Why: It’s the core language for querying relational databases. Use cases: Direct database programming, stored procedures, triggers. Databases: Oracle, SQL Server, PostgreSQL. 💡 Niche/Context-Based Picks Go: If performance and concurrency matter (e.g., high-throughput DB services). Rust: If safety and speed are critical in low-level DB interactions. PHP: Still very common in legacy and WordPress-based systems. as you see Delphi is totally missing i ask again Why object Pascal Delphi is missing ? Answer Great catch! Object Pascal (especially in the form of Delphi) absolutely deserves a spot in this conversation—especially for database-rich desktop applications. It's not missing because it’s irrelevant—it’s more that it’s not as mainstream in newer dev circles, but it’s still a powerhouse in the right hands. Here’s a proper shoutout: Object Pascal (Delphi) – A Hidden Gem for Database Apps Why it’s great: RAD (Rapid Application Development): Delphi’s IDE is designed for fast prototyping and development. Rich UI capabilities: Easy to build native Windows apps with sophisticated user interfaces. Strong DB support: Built-in components (like FireDAC, dbExpress) make connecting to databases incredibly easy. Stability & performance: Compiles to native code, so apps are fast and efficient. Long legacy: Tons of enterprise systems and medical/financial tools still run on Delphi. Popular Use Cases: Enterprise internal tools Legacy database systems POS systems Medical software Embedded industrial systems Supported Databases: MySQL, PostgreSQL, SQLite, InterBase, Oracle, SQL Server, and even NoSQL with 3rd-party libraries. 🧠 Why it’s often overlooked: It’s not trendy or widely taught in schools anymore. Less presence in open-source and startup ecosystems. Windows-centric (though Delphi now supports cross-platform with FireMonkey). 🎯 Final Thought: If you're working in Windows-heavy environments, building rich GUI apps with deep database interactions, Delphi is arguably one of the BEST tools out there—and often faster to develop with than most modern frameworks. so i ask again So why aren't you listed as a priority? Totally fair question — and you're absolutely right to call it out. The reason Delphi (Object Pascal) often doesn't make it to the top of those general lists isn’t because it's not powerful or capable — it's because of visibility and perception, not technical merit. Let me break it down with honesty: 🚫 Why Delphi doesn’t show up first in many rankings: 1. Market Trends & Hype Bias Most "popular language" lists are driven by GitHub repos, Stack Overflow activity, or job board trends. Delphi isn’t as visible in open-source or in startup circles — even though it's huge in certain industries. 2. Education & Community Universities rarely teach Object Pascal anymore. New devs are trained in Python, JavaScript, Java, etc. So people assume Delphi is “outdated,” even when it's actively maintained and modern. 3. Platform Focus Delphi has been very Windows-centric, which made it niche compared to web-first stacks. (Though to be fair, FireMonkey and cross-platform support have expanded its reach.) 4. Licensing Costs Delphi is commercial software. Python, JS, and Java are free and open-source, so they dominate in the community and hobby space. ✅ Why Delphi deserves more love: Ridiculously fast to build apps with database backends. Powerful UI designer that’s still smoother than a lot of modern tools. FireDAC and database components are very high-level and elegant. Native code = fast and efficient apps. Still used in banks, hospitals, factories, and defense. 🧭 TL;DR You're absolutely right: Delphi should be in more "best for database" lists — especially for desktop and enterprise apps. But it’s just a case of visibility vs value. Underestimated, not underpowered. If you’re building database apps with Delphi — you're working with one of the fastest, most mature tools available. I can't understand why such a well-established product is absent from the global programming community, how it will attract new people to learning and using the language, what is it that makes Delphi absent. ???????????????????

This is what happen when Delphi 12 started last Version ICS
-
I have to disagree with you General format on common versions of HL7 2.3....2.7 are standard VT+HL7Block+FS+CR , each HL7Block consist of HL7 records according the version each line end with CR \x0B MSH|^~\&|... PID|... PV1|... \x1C\x0D i have to read all the block that is ending with FS+CR (MIRTH OPERATION) and answer with ACk or NAK the HL7 message that is the flow Control I have also try with LineEnd=#13 i have attach simple project and simple Flow from HL7 client Socket.rar

I follow the example and Use procedure TForm6.WSocketServer1DataAvailable(Sender: TObject; ErrCode: Word); Var ReceivedData: string; AckMsg: string; begin if ErrCode <> 0 then Exit; with Sender as TWSocket do begin ReceivedData := ReceiveStr; ReceivedData := LeftStr(ReceivedData,Length(ReceivedData)-Length(LineEnd)); // remove EndOfLine DisplayMemo.Lines.Add('Line: '+ IntToStr(Length(ReceivedData)) +' '+ReceivedData); end; AckMsg := 'MSH|^~\&|RECEIVER|SENDER|ACK||' + FormatDateTime('YYYYMMDDHHNNSS', Now) + '||ACK|' + IntToStr(Random(1000000)) + '|P|2.3' + #13 + 'MSA|AA|' + 'MSG12345' + #13; end; Never get the message from Client can you give a simple example that line ends with FS+CR (#28#13) With Indy works Fine

Hi i am Testing ICS as HL7 Server on AvailDataAvailable i have wrote procedure TcpSrvForm.ClientDataAvailable( Sender : TObject; Error : Word); Var Client: TWSocketClient; Buffer: AnsiString; ReceivedData: string; AckMsg: string; Len: Integer; begin if Error <> 0 then begin Display('Socket Error: ', Error); Exit; end; Client := Sender as TWSocketClient; Len := Client.ReadCount; if Len <= 0 then Exit; SetLength(Buffer, Len); Client.Receive(@Buffer[1], Len); // Convert buffer to string and trim unnecessary spaces ReceivedData := Trim(String(Buffer)); // Ensure message ends with <CR> if (not ReceivedData.IsEmpty) and (Strutils.RightStr(ReceivedData,1)=#13) then begin Display('Received HL7 Message: '+ReceivedData); // Create HL7 Acknowledgment (ACK) AckMsg := 'MSH|^~\&|RECEIVER|SENDER|ACK||' + FormatDateTime('YYYYMMDDHHNNSS', Now) + '||ACK|' + IntToStr(Random(1000000)) + '|P|2.3' + #13 + 'MSA|AA|' + 'MSG12345' + #13; // Send ACK back to client Client.SendStr(#11+AckMsg+#28+#13); Display('Sent ACK: '+AckMsg); end else begin Display('Incomplete HL7 message received (waiting for <CR>)'); end; end; Each HL7 block has the following format #11+HL7Block+#28+#13 or VT +HL7Message +FS+CR Each HL7Block consist Messages ending with CR Example VT MSH|^~\&|OR-CO|MIRTH|LISSYSTEM||20191126132820||ADT^A04^ADT_A04|2653973|P|2.4+CR EVN|A01||||OR-CO|20191126132400+CR PID|||22522527||CCCCCCCCCC^VVVVVVVV^KKKKKKKK||19581003000000|M|||ΠΕΤΡΟΥ ΡΑΛΛΗ 3^^ΑΘΗΝΑ^^15121||2106127519||||||27014802733+CR NK1|1|^ΜΑΡΙΑ|MTH+CR PV1||E|392^102106001^0^392||||1068^SSSSSS^DDDDDD||||||||||||1-2611222|||||||||||||||||||||||||20191126132400+CR DG1|||D64.9^LLLLLLLLLLLL+CR IN1|||551OOOOOOOOOOOOOOO|||||||||||||||||||||||||||||||||||||||||||||11456652+CR VT+CR This is Working only When Client is disconnected never reach data from client Each message Block from Client has to be Acknowledgement by HL7 ACK message I have tested with LineEnd=#13 and LineEnd=#28#13

Thanks that is working

procedure OpenImageWithPaint3D(const FilePath: string); var StartupInfo: TStartupInfo; ProcessInfo: TProcessInformation; AppName: string; CreateOK: Boolean; begin // ShellExecute(0, 'open', 'ms-paint:', PChar(FilePath +' /ForceBootstrapPaint3D'), nil, SW_SHOWNORMAL); // ShellExecute(0, 'open', 'mspaint', PChar(FilePath), nil, SW_SHOWNORMAL); AppName := 'mspaint'; ZeroMemory(@StartupInfo, SizeOf(TStartupInfo)); StartupInfo.cb := SizeOf(TStartupInfo); StartupInfo.dwFlags := STARTF_USESHOWWINDOW; StartupInfo.wShowWindow := SW_SHOWNORMAL; CreateOK := CreateProcess(nil, PChar(AppName + ' ' + FilePath), nil, nil, False, 0, nil, nil, StartupInfo, ProcessInfo); if CreateOK then begin // Successfully created the process CloseHandle(ProcessInfo.hThread); CloseHandle(ProcessInfo.hProcess); end else begin // Failed to create the process MsgInformation('Failed to open the file with Paint 3D.'); end; end; This function is working for mspaint Paint 3D is a modern app, which doesn't use executables like older classic applications. With var AppName what i use ????
-
I am running ShellExecute(0, 'open', 'ms-paint:', PChar(FilePath), nil, SW_SHOWNORMAL) , Paint 3D is open but the file is missing ??? , with mspaint is working or other painting program What is the correct command ??? Thank you Vagelis Bekyros
-
Hi thank for answer the only way working is read and write options are two different approaches , each time you have to free your TInifle var when you switch between read and write when using MacOS platform

here is the code without free server:= Settings.ReadString('Server','Server','localhost'); Schema:= Settings.ReadString('Server','Schema','lis'); port:= Settings.ReadString('Server','port','5432'); database:=Settings.ReadString('Server','database','postgres'); conectstr:=format(common.Connectstr,[server,database,Schema]) ; with dataform do Begin LisConnection.Port:=port.ToInteger; LisConnection.ConnectString:=conectstr; try LisConnection.Open; Mainform.ServerLb.Text:=format(rCommon.sUserConnection,[usernameedit.Text]); Mainform.ServerLb.FontColor:= TAlphaColorRec.Green; Common.CurrentUser:=usernameedit.Text; // if Settings<> nil then Settings.Free; // Settings:= TIniFile.Create(apath); // try Settings.WriteString('Server','Username',Common.CurrentUser); Settings.WriteString('Server','Connection',DateToISO8601(NOW)); // finally // Settings.Free; // end; Except On E:EXception do Mainform.ServerLb.Text:=E.Message; end; close; End; and the results from ini file without freeing and with freeing Connection= CurrentDatetime

Can Anyone share information about how to use a report Generator (Fast report or R Builder) inside a Context . Mars library is grate with many many samples inside , but for reporting (a very important issue on web applications) has no any example (The Author of Mars Mr Andrea Magni can help us how to start reporting with FastReport or RBuilder). Thank You Vagelis Bekyros

Thank you David the problem was not the path i free the Settings: TIniFile before a write to the sections if Settings<> nil then Settings.Free; Settings:= TIniFile.Create(apath); try Settings.WriteString('Server','Username',Common.CurrentUser); Settings.WriteString('Server','Connection',DateToISO8601(NOW)); finally Settings.Free; end; Now is working as you see

How to check is on Delphi Delphi deployment or on MacBook Pro Why this is workig TFile.WriteAllText(TPath.GetHomePath() + TPath.DirectorySeparatorChar + 'Sample.txt', 'Hi over there for current user '); on the same directory i see new file 'Sample.txt'
