    <p>Sometimes oldschool pascal stylee is not that bad. Even though non-oo file access doesn't seem to be very popular anymore, <code>ReadLn(F,xxx)</code> still works pretty ok in situations like yours.</p> <p>The code below loads information (filename, source and version) into a <code>TDictionary</code> so that you can look it up easily, or you can use a listview in virtual mode, and look stuff up in this list when the <code>ondata</code> even fires.</p> <p>Warning: code below does not work with unicode.</p> <pre><code>program Project101; {$APPTYPE CONSOLE} uses IoUtils, Generics.Collections, SysUtils; type TFileInfo=record FileName, Source, Version:String; end; function LoadFileInfo(var aFileInfo:TFileInfo):Boolean; var F:TextFile; begin Result := False; AssignFile(F,aFileInfo.FileName); {$I-} Reset(F); {$I+} if IOResult = 0 then begin ReadLn(F,aFileInfo.Source); ReadLn(F,aFileInfo.Version); CloseFile(F); Exit(True) end else WriteLn('Could not open ', aFileInfo.FileName); end; var FileInfo:TFileInfo; Files:TDictionary&lt;string,TFileInfo&gt;; S:String; begin Files := TDictionary&lt;string,TFileInfo&gt;.Create; try for S in TDirectory.GetFiles('h:\WINDOWS\system32','*.xml') do begin WriteLn(S); FileInfo.FileName := S; if LoadFileInfo(FileInfo) then Files.Add(S,FileInfo); end; // showing file information... for FileInfo in Files.Values do WriteLn(FileInfo.Source, ' ',FileInfo.Version); finally Files.Free end; WriteLn; WriteLn('Done.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
