    splitting interface + implementation

    if I remember correctly it was in one of the Nick Hodges books - but that is off the top of my head without any guarantee

    Saving tree to Data Base

    I just played around and if you really only need to load a certain status into the database which you need to reload you could do something like this: procedure TForm2.btn1Click(Sender: TObject); var I: Integer; node: TTreenode; ms: TMemoryStream; begin node := tv1.Items.Add(nil, 'ROOT Beer') ; for I := 0 to 10 do begin tv1.items.AddChild(node, 'Beer ' + i.toString); end; ms := TMemoryStream.Create; tv1.SaveToStream(ms); qry_1.SQL.Text := 'Insert into files (files) values (?)'; qry_1.Params[0].LoadFromStream(ms, ftBlob); qry_1.ExecSQL(); ms.Clear; qry_1.SQL.Text := 'Select f.files from files f limit 1'; qry_1.Open(); ms.Position := 0; TBlobField(qry_1.FieldByName('files')).SaveToStream(ms); ms.Position := 0; tv2.LoadFromStream(ms); ms.Free; end; just a quick and dirty hack with two treeviews (tv1, tv2) and Firedac on SQlite

    Sql-Add Number begining of an INT field

    My solution was based on the fact that it is an integer field - therefore a simple "ADD" seamed to be the most straightforward way. I am not working on interbase. Therefore my SQL is based on SQlite. There you could use UPDATE mytable SET docno = CASE WHEN docno <2000 THEN docno + 210000 ELSE docno + 220000 END; which would give you more flexibility. In SQLite you could also do UPDATE mytable SET docno = CASE WHEN docno <2000 then '21'|| DOCNO ELSE docno + 220000 END; since SQLite internally handles the fields as strings. But case can give you flexibility in case you need it

    Sql-Add Number begining of an INT field

    How about Update mytable set docno = docno + 210000; this modifies all records. If you want to limit the affected rows you would need to add a WHERE clause

    Android Mobile application using Firemonkey

    sorry to say - but not appealing to me. Components limited to Android Firemonkey? - This is odd as Firemonkey is supporting iOS, Windows, MacOS Did you look at TMS FNC framework - one of my favourites for GUI development
  9. I started to work with the new JetBrains Mono - really nice

    New project with embedded browser

    Thanks for sharing - my understanding is that the FMXBrowser is independent of the framework. @Dave NottageWould you share all your enhancements or do you host it somewhere? Github? I think it would be much appreciated

    Database connection as parameter in class creation

    Thanks for the feedback and the valuable input Free will be part of the datamodule when it is destroyed 🙂
  14. Hi, in a program I have a central FireDAC connection to my database in a datamodule. I intend to have all record related activities (CRUD) in a class that holds the record. My questions are: 1) is there any penalty if I pass the connection (as var parameter?) to the constructor of the class? 2) is this the best way to separate the data from the UI? many thanks in advance Gernot
