I'm still on 11.3 and soon will switch to 12. I just see in the video that this new JSON feature is now in Delphi 12... Is it working as I think it's working ?? After reading the JSON it's possible to directly access the keynames (email, address.street, ..) to get the values as weaktype languages can do, like Javascript.

Whatever you program in Delphi, compared with most other languages, it will stay RAD and you can focus on you actual problem instead for example fighting how to put things on the screen. It takes the Online department, with Node, Javascript and pumping JSON files through the internet, with three developers (backend, frontend and HTML/CSS designer) about one week for one screen. They calling Delphi old fashioned while I look to their source and problems as if they still live in the 1980's.

I have noted something like this by the {$IFDEF DEBUG} switch in D11.3. When switching the "Build Configurations" from Debug to Release nothing happens. When staying in the Unit and do Compile or Build nothing happens. but When I switch in the editor from that source/unit tab to another source and back it works and the editor will gray-out the proper sourcecode.

Yes, but the use is not to get a clean 100% translation. It will give you a lot of insight of the differences between Delphi/Pascal and C keywords/declarations etc.. >It will probably be a bit stubborn since it's so much code, so you'll have to step through it Yes, like the programmer that has to translate the code..

Yes, try Chat-GPT to translate sourcecode. It is quite good in it..

For a (very) long time I use dataobjects to query the database and I'm still very happy about it. I would otherwise get mad hiding all the actual queries away from sourcecode by adding them in the TFDQuery properties. If you do it in the classic way using a datamodule then in the long run with large applications you will end up with a lot of TFDQueries on the module and your application will start very slow. For example to use the DataObject looks like this: MyDataObject:=TMyDataObject.Create('DatabaseName'); try MyDataObject.Code:='1234'; If not MyDataObject.qryMyName.eof then Begin txtEdit.Text:=MyDataObject.Name; End; Finally MyDataObject.Free; End; You can decide to make such dataobject for every table in your database. Use the main table if you have Joins in the Query. If you have a new query you add a new Setter in the object. In this way you can reuse the queries in your entire code. (or in a comple other project/application) For example if your TFDQuery is in the Public section you can still do things in the GUI like: MyDBGrid.Datasource.DataSet:=MyDataObject.qryMyName; Note: If you need more parameters in your query you can create the property like: property CodePersonsID[aCode: Integer] : Integer write SetCodePersonsID; procedure SetCodePersonsID(aCode: Integer; aPersonsID: Integer); MyDataObject.CodePersonsID[45]:=99888; A simple DataObject can look like this: TMyDataObject = Class(TObject) Private fDataBaseName: String; protected procedure SetCode(aCode : String); function GetCode : String; function GetName : String; Public qryMyName : TFDQuery; procedure All; property Code : String read GetCode write SetCode; property Name : String read GetName; Constructor Create(aDataBaseName: String); Destructor Destroy; Override; End; implementation uses SysUtils; Constructor TMyDataObject.Create(aDataBaseName: String); Begin Inherited Create; fDataBaseName:=aDataBaseName; //Create here your own TFDQuery.Create procedure.. database_initQuery(fDataBaseName, 'qryMyName', qryMyName); End; Destructor TMyDataObject.Destroy; Begin If qryMyName<>NIL then qryMyName.Free; Inherited Destroy; End; procedure TMyDataObject.All; Var SQLText : String; Begin SQLText:='select * from "MyTable" '; qryMyName.Active:=False; qryMyName.SQL.Clear; qryMyName.SQL.Add(SQLText); qryMyName.Active:=True; qryMyName.First; End; procedure TMyDataObject.SetCode(aCode : String); Var SQLText : String; Begin SQLText:='select * from "MyTable" where Code= :CODE'; qryMyName.Active:=False; qryMyName.SQL.Clear; qryMyName.SQL.Add(SQLText); qryMyName.ParamByName('CODE').AsString:=aCode; qryMyName.Active:=True; qryMyName.First; End; Function TMyDataObject.GetCode : String; Begin With qryMyName do Begin if FindField('code')<>NIL then Result:=FieldByName('code').AsString else Result:=''; End; End; Function TMyDataObject.GetName : String; Begin With qryMyName do Begin if FindField('name')<>NIL then Result:=FieldByName('name').AsString else Result:=''; End; End;

I just testing this ChatGPT IDE implementation and I thought let's give it a shot. //To ensure that XE interprets the strings correctly, //you can try explicitly setting the encoding when reading //the strings from the data file. //Here's an example of how you could modify your code to //read the strings as Windows 1252 encoded: delphi procedure TForm1.FormActivate(Sender: TObject); var morphlex: file of string[32]; str: AnsiString; nooflexrecs: Integer; begin AssignFile(morphlex, 'MorphIr.dat'); Reset(morphlex); nooflexrecs := FileSize(morphlex); ShowMessage('Data file contains ' + IntToStr(nooflexrecs) + ' records'); // Read strings using Windows 1252 encoding while not Eof(morphlex) do begin BlockRead(morphlex, str, SizeOf(str)); // Convert string to Unicode if needed ShowMessage(TEncoding.GetEncoding(1252).GetString(PAnsiChar(str))); end; CloseFile(morphlex); end; //In this updated code snippet, we use `AnsiString` to //read the string data from the file as it is not Unicode. //We then convert the `AnsiString` to Unicode using //the `TEncoding.GetEncoding(1252).GetString` method to //interpret the Windows 1252 encoded strings correctly. //Please note that this code assumes that the string data //in the file is in Windows 1252 encoding. //If the actual encoding is different, you may need to //adjust the encoding parameter accordingly

The plug-in is working great and the warning is indeed not a problem. 👍 I've downloaded the ZIP from GitHub and build/installed the *.dpk file and that went very smooth. The message I got directly after installing the plug-in. From the IDE main menu I opened the Chat-GPT settings and pasted the API-key and did Save/Close without any other input in the setting dialog.

What makes it that it thinks that I use an offline server?

You can consider not to use the INI but the Windows Credential Manager for storing information. Very easy to use (read/write) from Delphi.

Which database?

>>without creating a new component? >>and I think about a new VCL. Sounds a bit strange.. Don't modify the original VCL component (if you have the Delphi sourcecode..) Modifying_Existing_Controls

This native client 11 driver was for us the only one that was usable for 2012, 2014 and maybe for your 2017 too. We went to the latest MSSQL sever recently and for that server we needed one of the latest driver and indeed the Native Client 11 driver will not work anymore. We use SQL ODBC 18 at the moment. I had a machine that was not working good either and the trick was to install the MSSQL Server Management Studio on that machine. The Studio also installs a driver and other dependencies.

Did you tried the "SQL Native Client" driver?

Like Peter said. Check your idx AFTER the call statement. Tested in Delphi 11.3

Sometimes this happens. Whitelist the App in the virus software.

I took over a Delphi Mormot webserver with source and both Get (root) and Post (rootp) are implemented. GET implementation FModel := TSQLModel.Create([], StringToUTF8(fRoot)); FServer := TSQLRestServerFullMemory.Create(FModel, 'test.json', False, False {true}); FServer.ServicesRouting := TSQLRestRoutingREST2; POST implementation FModel_Post := TSQLModel.Create([], StringToUTF8(fRootPost)); FServer_Post := TSQLRestServerFullMemory.Create(FModel_Post, 'test.json', False, False {true}); FServer_Post.ServicesRouting := TSQLRestRoutingJSON_RPC2; //I can change this (to Rest?) if needed because the POST method is not used yet.. There is a test function Add and is called by the client as: localhost:8181/root/<ApplicationName>/Add?n1=1&n2=5 (with http://) Now I want to use the POST method of the server and test it with a small HTTP client program to call the add function. I have tried a lot of ways but no success.. (Bad Request) For example: PostData := TStringList.Create; try PostData.Add('{"n1":1,"n2":5}'); Param:='http://localhost:8181/rootp/<ApplicationName>.Add'; IdHTTP1.HTTPOptions := IdHTTP1.HTTPOptions + [hoNoProtocolErrorException, hoWantProtocolErrorContent]; IdHTTP1.Request.ContentType := 'application/json'; IdHTTP1.Request.Accept := 'application/json'; IdHTTP1.Request.CacheControl := 'no-cache'; ReceiveData:=IdHTTP1.POST(Param,PostData); Finally PostData.Free; End; What is the proper way to use the POST request ? Thanks.

I've tried that but what I understand is that declaration with the slash is when you create the server with the TSQLRestRoutingREST2 servicerouting instead of TSQLRestRoutingJSON_RPC2. When trying to use parameters the server responds with: { "errorCode":406, "errorText":"sicShared execution failed (probably due to bad input parameters: e.g. did you initialize your input record(s)?) for ScenarioAnalyseTester.Add" } The POST method is working when the server is started with TSQLRestRoutingREST2 and the whole URL string is like the Get method: localhost:8181/root/<ApplicationName>/Add?n1=1&n2=5 and leave the parameters empty but I guess there must be a way to get the result by using the "rootp" server with TSQLRestRoutingJSON_RPC2 and the parameters field of the POST method..

If you add the connection by the data explorer you get a wizard that can help you to get the proper parameters for your .ini file Are you sure that the database parameter in your ini must be ";DAtabase = qclocal;" (not sure if it is case sensitive.. DAtabase?)

Did you try to add and test the connection by the Delphi Data Explorer? (Menu-View-Tool Windows-Data Explorer)
