@Squall_FF8 DataModule.LookupDatasetField1.DisplayWidth := 10; DataModule.LookupDatasetField2.DisplayWidth := 20; DataModule.LookupDatasetField3.DisplayWidth := 30;

You need to set the DisplayWidth property for the list fields of the list lookup dataset. AFAIK no.

Definitely. But time is money. If Copilot can do it for you - why not? for Line in Lines do --> Line := Lines.Text;

Copilot. The result: program FormatStringExtractor; uses SysUtils, Classes; function ContainsPlusBeforeComma(const S: string): Boolean; var PlusPos, CommaPos: Integer; begin PlusPos := Pos('+', S); CommaPos := Pos(',', S); Result := (PlusPos > 0) and (CommaPos > PlusPos); end; procedure ProcessFile(const FileName: string; LogFile: TStrings); var Lines: TStringList; Line, SubStr: string; StartPos, EndPos: Integer; begin Lines := TStringList.Create; try Lines.LoadFromFile(FileName); for Line in Lines do begin StartPos := Pos('Format(', Line); while StartPos > 0 do begin EndPos := PosEx('])', Line, StartPos); if EndPos > 0 then begin SubStr := Copy(Line, StartPos, EndPos - StartPos + 2); if ContainsPlusBeforeComma(SubStr) then LogFile.Add(SubStr); // Move the start position forward to find the next occurrence StartPos := PosEx('Format(', Line, EndPos + 2); end else Break; end; end; finally Lines.Free; end; end; procedure ProcessFolder(const Folder: string; LogFile: TStrings); var SearchRec: TSearchRec; FullPath: string; begin if FindFirst(Folder + '\*.*', faAnyFile, SearchRec) = 0 then begin repeat FullPath := Folder + '\' + SearchRec.Name; if (SearchRec.Attr and faDirectory) = faDirectory then begin if (SearchRec.Name <> '.') and (SearchRec.Name <> '..') then ProcessFolder(FullPath, LogFile); end else if ExtractFileExt(SearchRec.Name).ToLower = '.pas' then begin ProcessFile(FullPath, LogFile); end; until FindNext(SearchRec) <> 0; FindClose(SearchRec); end; end; var Folder: string; LogFile: TStringList; begin Write('Enter folder path to scan: '); ReadLn(Folder); LogFile := TStringList.Create; try ProcessFolder(Folder, LogFile); LogFile.SaveToFile('format.log'); WriteLn('Strings saved to format.log'); finally LogFile.Free; end; end.

Can you please elaborate this? Maybe a short article on this topic. P.S. I've noticed that there have been several interesting Delphi projects from Brazilian developers lately. Skia for Delphi, D2Bridge Framework are the most notable.

Multiline strings '''...''' were a very nice addition to the language. Still waiting for constructions like case string1 of 'aaa':... DoubleValue := Variant1 if not VarIsNull(Variant1) else 0.0;

There are three things you can watch forever: fire, water, and code improving. procedure TLinkMemo.CNCommand(var Message: TWMCommand); begin inherited; case Message.NotifyCode of EN_VSCROLL: SyncLink(True); EN_HSCROLL: SyncLink(False); end; end; procedure TLinkMemo.SyncLink(Vertical: Boolean); const BAR_FLAGS: array[Boolean] of Integer = (SB_HORZ, SB_VERT); MSGS: array[Boolean] of Cardinal = (WM_HSCROLL, WM_VSCROLL); var scrollInfo: TScrollInfo; begin if LinkedMemo = nil then Exit; var savedLink := LinkedMemo.LinkedMemo; try LinkedMemo.LinkedMemo := nil; scrollInfo.cbSize := SizeOf(scrollInfo); scrollInfo.fMask := SIF_POS; if GetScrollInfo(Handle, BAR_FLAGS[Vertical], scrollInfo) then LinkedMemo.Perform(MSGS[Vertical], MAKEWPARAM(SB_THUMBPOSITION, scrollInfo.nPos), 0); finally LinkedMemo.LinkedMemo := savedLink; end; end; procedure TLinkMemo.WMHScroll(var Message: TMessage); begin inherited; SyncLink(False); end; procedure TLinkMemo.WMVScroll(var Message: TMessage); begin inherited; SyncLink(True); end;

@limelect How do you scroll horizontally? I know some programs allow this by holding the shift key down while you operate the scroll wheel. But in our case it doesn't work. I can scroll horizontally by dragging the bottom slider on the scroll bar, or by moving the cursor to the end of the line with the keys.

OK I checked my code on Windows 7 in VirtualBox. Works like a charm.

@limelect It's strange. Works fine for me on Windows 10. (Screencast attached). SyncScroll.mp4

OK, my take. unit Unit1; interface uses Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls; type TLinkMemo = class(TMemo) private FLinkedMemo: TLinkMemo; procedure SyncLink; protected procedure WndProc(var Message: TMessage); override; public property LinkedMemo: TLinkMemo read FLinkedMemo write FLinkedMemo; end; TMemo = class(TLinkMemo); TForm1 = class(TForm) Memo1: TMemo; Memo2: TMemo; procedure FormCreate(Sender: TObject); private public end; var Form1: TForm1; implementation {$R *.dfm} procedure TLinkMemo.WndProc(var Message: TMessage); begin inherited; if (LinkedMemo = nil) or not LinkedMemo.HandleAllocated then Exit; case Message.Msg of WM_HSCROLL, WM_VSCROLL, WM_KEYDOWN, WM_MOUSEFIRST..WM_MOUSELAST: SyncLink; end; end; procedure TLinkMemo.SyncLink; procedure UpdateScrollBar(BarFlag: Integer; Msg: Cardinal); var scrollInfo: TScrollInfo; begin scrollInfo.cbSize := SizeOf(scrollInfo); scrollInfo.fMask := SIF_POS; if GetScrollInfo(Handle, BarFlag, scrollInfo) then LinkedMemo.Perform(Msg, MAKEWPARAM(SB_THUMBPOSITION, scrollInfo.nPos), 0); end; var savedLink: TLinkMemo; begin savedLink := LinkedMemo.LinkedMemo; try LinkedMemo.LinkedMemo := nil; UpdateScrollBar(SB_HORZ, WM_HSCROLL); UpdateScrollBar(SB_VERT, WM_VSCROLL); finally LinkedMemo.LinkedMemo := savedLink; end; end; procedure TForm1.FormCreate(Sender: TObject); begin Memo1.LinkedMemo := Memo2; Memo2.LinkedMemo := Memo1; end; end.

@limelect I guess you've over-engineered it a bit. @Uwe Raabe gave a great variant, it just needs a bit of tweaking. unit Unit1; interface uses Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls; type TLinkMemo = class(TMemo) private FLinkedMemo: TLinkMemo; procedure WMVScroll(var Message: TMessage); message WM_VSCROLL; procedure WMHScroll(var Message: TMessage); message WM_HSCROLL; procedure CNCommand(var Message: TWMCommand); message CN_COMMAND; procedure SyncLink; public property LinkedMemo: TLinkMemo read FLinkedMemo write FLinkedMemo; end; TMemo = class(TLinkMemo); TForm1 = class(TForm) Memo1: TMemo; Memo2: TMemo; procedure FormCreate(Sender: TObject); private public end; var Form1: TForm1; implementation {$R *.dfm} procedure TLinkMemo.SyncLink; var savedLink: TLinkMemo; myLine, linkLine: Integer; begin if LinkedMemo = nil then Exit; savedLink := LinkedMemo.LinkedMemo; try LinkedMemo.LinkedMemo := nil; LinkedMemo.CaretPos := CaretPos; LinkedMemo.Perform(EM_SCROLLCARET, 0, 0); myLine := Perform(EM_GETFIRSTVISIBLELINE, 0, 0); linkLine := LinkedMemo.Perform(EM_GETFIRSTVISIBLELINE, 0, 0); if myLine <> linkLine then LinkedMemo.Perform(EM_LINESCROLL, 0, myLine - linkLine); finally LinkedMemo.LinkedMemo := savedLink; end; end; procedure TLinkMemo.CNCommand(var Message: TWMCommand); begin inherited; if (Message.NotifyCode = EN_VSCROLL) or (Message.NotifyCode = EN_HSCROLL) then SyncLink; end; procedure TLinkMemo.WMVScroll(var Message: TMessage); begin inherited; SyncLink; end; procedure TLinkMemo.WMHScroll(var Message: TMessage); begin inherited; SyncLink; end; procedure TForm1.FormCreate(Sender: TObject); begin Memo1.LinkedMemo := Memo2; Memo2.LinkedMemo := Memo1; end; end.

@Uwe Raabe I hope the original author (notme) of the snippet has already done this. I've posted it here as a curious fact for those interested (like me). I haven't encountered any internal compiler errors in Delphi in recent years. Although, perhaps this bug has already been fixed in 12.2. (I have 12.1 CE).
