I suggest this as a one shot solution (quick and forget) , not for a runtime application 😉

Hum, I was not aware of but in my mind if there is a JDBC driver for Interbase (and there is one) it was possible to connect Dbeaver to Interbase. Thanks Firedac and TFDBatchmove ! Except for, and I am not sure of the "except" I just don't test but as I remember output table can be created with same structure input table, creating the table you don't have to write an executable program just in design time you can do the transfer data from table to table. Put 2 connections (one SQlite, other Interbase) 2 related FDTables (or FdQuerys), one FdBatchMove, one FDBatchMoveDatasetReader (for sqlite side) one FDBatchMoveDatasetWriter (for guess wat ;-)) and then you can execute fdbatchmove (contextual menu) during designtime

Hi, I don't use DBeaver for that but have a look to this GUI

Panel is no more than a TRectangle (depending style file I think) I don't know why but if you try to change TPanel fill color this does not work with 'windows 10 desktop style' , works during design time with 'default' Stylecollection but not at runtime 🐛something to do with the fact that this TRectangle is at the root and not in a TLayout ? Best suggestion I can do is : use a TRectangle. I do not use anymore TPanel now, preferring Layouts and TRectangle 😉

As I understand what is in your mind, I think it's your ChangeObjectRecursive function the problem. A component (your panel) as style but style is not the "container" of the panel's childs. And therefore, you change wrong "styledata" property for a label See this : // Changing all labels of a panel randomly procedure TForm112.Button1Click(Sender: TObject); var aColor : TAlphaColor; procedure ChangePanelLabels(const Panel : TPanel; const ChangeToColor : TAlphaColor); var i : integer; begin if SameText(Panel.StyleLookup,'panel1style1') then begin for i:=0 to Panel.Children.Count - 1 do begin if Panel.Children[i].ClassNameIs('TLabel') then TLabel(Panel.Children[i]).StylesData['Text.TextSettings.FontColor']:= ChangeToColor; end; end; end; begin randomize; aColor:=Random($FFFFFF) OR $FF000000; // add alpha layer ChangePanelLabels(Panel1,aColor); end;

%s is yet a string so it's somewhere normal Try FormatDateTime('dd.mm.yyyy',value) or declare your fields, set your date field displayformat property to 'dd.mm.yyyy' and use displaytext in customformat

Hi, I found a way to sort my lists using Sort an OnCompare event but I don't figure out a functional way to use Sort(Compare) method (Rio 10.3.3) Any clues ? Thanks

Sorry, not being specific. Late I found, really by chance, why the code I used procedure TForm110.btnDetailClick(Sender: TObject); // numeric sort on detail var Compare : TFMXObjectSortCompare; begin Tri:=btnDetail.Tag; if btnDetail.Tag=1 then btnDetail.Tag:=0 else btnDetail.Tag:=1; ListBox1.Sorted:=False; Compare:=function(item1, item2: TFmxObject): Integer var n1,n2 : Single; begin n1:=StrToFloatDef(TListBoxItem(item1).ItemData.Detail,0); n2:=StrToFloatDef(TListBoxItem(item2).ItemData.Detail,0); if n2=n1 then result:=0 else begin if n2>n1 then Result := 1 else Result := -1; end; if tri=0 then result:=result*-1; end; ListBox1.Sort(Compare); // here end; seems to be useless. Just resizing the form (to take a picture) 'refreshed' the aligned list. Before solving, I used a BeginUpdate/EndUpdate sequence with no effect ! So that was why I don't understood the usage of list.sort(compare) was not 'working'. A self.width:=self.width+1; self.width:=self.width; confirmed that but was not the solution. Finally, digging in the source code, I found the solution ListBox1.RealignContent; Just after the sort did it. Joined, comparative runtime screens (first alpha sort on text using sorted:=true, second numeric sort on detail using sort(compare) twice to have DESC order)

A close no, but an unprepare should be to check. If your first SQL works, other request just changing parameter works. i.e dm.fdq.Open('',[ 2 ] ); It's when you change the SQL and parameters the problem.

Well don't be so afraid. I think you can use a TFrame (somewhere TFrame is like a style) for all that filling stuff. I think it was the Paul Toth approach.

Hi, I never thought about including animation in a ListView but, why not 😉 However my guess is TListView is not a good candidate for this sort of usage. Instead think about the ancestor, a TScrollBox. In my mind, this Jaques Nascimento video or videos from CodeRage2019 (Paul Thoth and Adriano Santos interventions)

Hello, This was a question I had in mind for a long time. I used to use, like ergeka and, even, closing the query before (old BDE comportment) dm.fdc.Close; dm.fdc.parambyname('Pc').asString:='Woolworths'; dm.fdc.Open; So, today, I make a little test and Firedac is really an amazing thing dm.fdc.Open,('',[ 'Woolworths' ]); works. One only line versus 2 (three in my case) and shorter than this ParambyName stuff. I certainly use this for now 😉 By the way I test also this query Select * from tTable where Company = ? order by oOrderName a no named parameter. It works too 👍

An argument : Firedac is BDE like (this mean all the old "BDE code" could be used as is) but is much more 😉

Hi, You are not alone 😉 even if BDE is largely obsolete I still have some fights with it. My suggestions to use it in a MS UAC environment (from Vista and more) : Don't use "program files" folders, install it in a root base directory (i.e. c:\borland\BDE) After install change some options : NET DIR directory (configuration/native/Paradox SHAREMEMxx values (configuration/system/init) (check this document for values) Last, don't forget to put Object/Options/ save for use with windows 3.1 and windows 95/NT << yes this can be a bit strange and prove obsolescence, as far as I understand this indicates BDE to find IDAPI32.cfg file and not in registry , as you certainly knows registry, UAC and users are not very friendly Installing BDE ? I use a setup I found with one of my older Delphi version (D2010 I think), but some installers (don't know if it's legal) can be found on the web i.e here or there be aware that BDE installer from Code Central need IDE to be installed on the PC I use version 5.0.1, note : last version was 5.2 I think I can't understand this, Firedac is much more than BDE ! Ok, if they still use paradox, db tables but wow ...

You can simplify all this, at design time the link is well known and named (LinkGridtodatasourcexxxxxx). Just rename your link in the BindingsList to grZasobaLink

A pleasure 😉 . But this still does not satisfy me fully, so I persist. My goal was to have the members linked even if no columns were defined, I found a way applying the principle : "if no columns are defined then all fields of the datasource are displayed". Having the linked datasource is easy TLinkGridToDatasource(B).DataSource, having the member list not so but I found that TBaseObjectBindSource have an interface IScopeMemberNames private ColumnList : TStringList; procedure TForm1.Button1Click(Sender: TObject); var B : TContainedBindComponent; SL : TStringList; S : String; IMembers : IScopeMemberNames; ib : integer; begin for ib:=0 to BindingsList1.BindCompCount-1 do begin B:=BindingsList1.BindComps[ib]; if (B.ControlComponent is TCustomGrid) then begin if TBaseObjectBindSource(TLinkGridToDatasource(B).DataSource).GetInterface(IScopeMemberNames,IMembers) then begin IMembers.GetMemberNames(ColumnList); for S in ColumnList do Memo1.Lines.Add(S); end; end; end; end; Now it's just a question of using a StringList to store the fieldnames and to arrange it function of the grid (defined columns, and move), more "classic code" I think even if, at this time, I have no idea (Sunday not propitious to ) P.S. The only way I think about is to have a sort of SaveGridSettings / LoadGridSettings procedure something using ObjectBinaryToText and reverse function SaveGridSettings(Component: TComponent): string; var BinStream:TMemoryStream; StrStream: TStringStream; s: string; begin BinStream := TMemoryStream.Create; try StrStream := TStringStream.Create(s); try BinStream.WriteComponent(Component); BinStream.Seek(0, soFromBeginning); ObjectBinaryToText(BinStream, StrStream); StrStream.Seek(0, soFromBeginning); Result:= StrStream.DataString; finally StrStream.Free; end; finally BinStream.Free end; end;

Agree with NIRAV KAKU in the principle but anyway if you want to access LiveBinded fieldname of a column, fieldname is the wrong name you have to search a membername. My test in ideal conditions (only one StringGrid, only Stringgrid is Binded) Consider this code, list of all columns linked procedure TForm1.Button1Click(Sender: TObject); var B : TContainedBindComponent; C : TLinkGridToDataSourceColumns; ib,ic : integer; begin // have to search in the whole bindingslist for ib:=0 to BindingsList1.BindCompCount-1 do begin B:=BindingsList1.BindComps[ib]; // check if the component is the stringgrid if (B.ControlComponent=StringGrid1) then begin // look for all linked columns for ic := 0 to TLinkGridToDatasource(B).Columns.Count-1 do begin C :=TLinkGridToDataSourceColumns(TLinkGridToDatasource(B).Columns); Memo1.lines.add(c[ic].MemberName); end; end; end; end; From this you can write a function, something like function FieldNameOfGrid(const Grid : TCustomGrid; col : integer) : String function TForm100.FieldNameOfGridCol(const Grid: TcustomGrid; const col: Integer): String; var B : TContainedBindComponent; ib : integer; begin for ib:=0 to BindingsList1.BindCompCount-1 do begin B:=BindingsList1.BindComps[ib]; if (B.ControlComponent=Grid) then try result:=TLinkGridToDataSourceColumns(TLinkGridToDatasource(B).Columns)[col].MemberName; break; except result:=''; end; end; end; Perfectible I think but working, even with unlinked columns, but only if columns are defined

Hi, sounds strange, but I am not an apple owner Hum, you want to say DisplayText ? I report, I think about two times https://quality.embarcadero.com/browse/RSP-22962 , this bug. If you want to use the format of livebindings try to use Format('%%.2f', 1*value)

Hum ! I was convinced my picture explain the whole thing In my sample (pro app i'm writing) it's work, and description you gave seem to be the same goal. I resume : a TListview (live)binded to a BindSourceDB, linked to a Dataset (whatever could it be Firedac, ClientDataset even TProtypeBindSource) fields of this one declared and some, here your currency field, with their DisplayFormat set. Take care one thing, you have to change those 'displaytext' in the FillExpressions collection one or more picture to see where you encounter difficulties (even a dfm part of the form) should be a good thing ie. object bndngslst1: TBindingsList Methods = <> OutputConverters = <> Left = 20 Top = 5 object LinkListControlToField1: TLinkListControlToField Category = 'Liaisons rapides' DataSource = bndQFacture Control = lvFactures FillExpressions = < item SourceMemberName = 'ANNEE' ControlMemberName = 'NumeroFacture' CustomFormat = '%s+'#39'-'#39'+DataSet.NUMERO.Text+'#39' ('#39'+DataSet.PART.Text+'#39')'#39 end item SourceMemberName = 'NOM' ControlMemberName = 'Client' end item SourceMemberName = 'ECHEANCE' ControlMemberName = 'Echeance' CustomFormat = 'DisplayText+'#39' '#39'+Dataset.MODE_PAIEMENT.Text' end item SourceMemberName = 'MONTANT' ControlMemberName = 'Montant' end> FillHeaderExpressions = <> FillBreakGroups = <> end end

Hi, in Binding expressions Customformat use DisplayText, see image attached. (Still filling DisplayFormat of the fields 😉) That's the easiest way, you can also use Format bindingList method but be careful syntax is slightly different the one we use in programs

Hi, you forgot to set image and accessory not visible.

Well, sorry if it's too late, i saw this post today. "Yes you can" , playing with the ItemHeight, alas this height is an integer and can't be lesser than 1 (0 => default size) so you will obtain a gray gap more or less high depending on items count in the group I explain how in this blogpost (sorry french only)

Hi, Pushing limits of TListBox and TListView I am testing FillBreakGroups collection (you can see my firsts steps here). Ok, that works fine was my first thoughts. Writing a new tutorial about list and livebindings, I create a new project and saw that using synchronize link and FillBreakGroups does not work is this not supposed to or is this a bug ? note : my tests are only on 10.3.2 version

You have one linked to my blog post. To see the behavior that I denounce, you only have to use livebindings editor and synchronize,accepting link change, and renaming this new link (not fair hu ?) On the other hand, i am working on another sample (using the well-known biolife.cds) but it is not ready yet, mainly because i have some other functionalities (i.e. custom search) Here some screenshots (capture and capture_1 without synchronization, last one with synchronization) , same code procedure TMainForm.rdbListBoxChange(Sender: TObject); var AFillBreakGroup : TFillBreakGroupItem; begin LinkListBoxGroup.Active:=False; if TRadioButton(Sender).IsChecked then begin case TRadioButton(Sender).tag of 0 : begin LinkListBoxGroup.FillBreakGroups.Clear; LinkListBoxGroup.FillBreakFieldName:=''; LinkListBoxGroup.FillHeaderFieldName:=''; ClientDataSet1.IndexFieldNames:=''; end; 1 : begin LinkListBoxGroup.FillBreakGroups.Clear; LinkListBoxGroup.FillBreakFieldName:='Category'; LinkListBoxGroup.FillHeaderFieldName:='Category'; ClientDataSet1.IndexFieldNames:='Category'; end; 2 : begin ClientDataSet1.IndexFieldNames:='Length (cm)'; LinkListBoxGroup.FillBreakFieldName:='Length (cm)'; LinkListBoxGroup.FillHeaderFieldName:=''; // créer les groupes aFillBreakGroup:=LinkListBoxGroup.FillBreakGroups.AddItem; AFillBreakGroup.MinValue:='0'; AFillBreakGroup.MaxValue:=30.ToString; AFillBreakGroup.DisplayText:='Petits'; aFillBreakGroup:=LinkListBoxGroup.FillBreakGroups.AddItem; AFillBreakGroup.MinValue:=30.ToString; AFillBreakGroup.MaxValue:=60.toString; AFillBreakGroup.DisplayText:='Moyens'; aFillBreakGroup:=LinkListBoxGroup.FillBreakGroups.AddItem; AFillBreakGroup.MinValue:=60.ToString; AFillBreakGroup.MaxValue:=90.ToString; AFillBreakGroup.DisplayText:='Gros'; aFillBreakGroup:=LinkListBoxGroup.FillBreakGroups.AddItem; AFillBreakGroup.MinValue:=90.ToString; AFillBreakGroup.DisplayText:='Enormes'; end; end; end; LinkListBoxGroup.Active:=True; end;
