    <p>You can use the method of getting a file version information. First we'd get <code>iexplore.exe</code> path.</p> <pre><code>function GetIEPath: string; var Reg: TRegistry; Len: Integer; begin Result := ''; Reg := TRegistry.Create; with Reg do begin try RootKey := HKEY_CLASSES_ROOT; OpenKeyReadOnly('CLSID\{0002DF01-0000-0000-C000-000000000046}\LocalServer32'); try Result := ReadString(''); finally CloseKey; Len := Length(Result); if Len &gt;= 2 then begin if(Result[Len] = '"') then Delete(Result, Len, 1); if(Result[1] = '"') then Delete(Result, 1, 1); end else begin Result := ''; end; end; finally Free; end; end; end; </code></pre> <p><code>{0002DF01-0000-0000-C000-000000000046}</code> is the CLSID for Internet Explorer. The default key value for <code>LocalServer32</code> is <code>iexplore.exe</code> path.</p> <p>Then, we use some API calls, as demonstrated by Simon Grossenbacher, on <a href="http://www.swissdelphicenter.ch/torry/showcode.php?id=27" rel="nofollow">this link</a>, to get a file version info. Modifying his function, we get to this:</p> <pre><code>function GetIEVersion: string; var IEPath: string; VerInfoSize: DWORD; VerInfo: Pointer; VerValueSize: DWORD; VerValue: PVSFixedFileInfo; Dummy: DWORD; begin Result := '0'; IEPath := GetIEPath; if IEPath = '' then Exit; VerInfoSize := GetFileVersionInfoSize(PChar(IEPath), Dummy); if VerInfoSize = 0 then Exit; GetMem(VerInfo, VerInfoSize); GetFileVersionInfo(PChar(IEPath), 0, VerInfoSize, VerInfo); VerQueryValue(VerInfo, '\', Pointer(VerValue), VerValueSize); with VerValue^ do begin Result := IntToStr(dwFileVersionMS shr 16); Result := Result + '.' + IntToStr(dwFileVersionMS and $FFFF); Result := Result + '.' + IntToStr(dwFileVersionLS shr 16); Result := Result + '.' + IntToStr(dwFileVersionLS and $FFFF); end; FreeMem(VerInfo, VerInfoSize); end; </code></pre> <p>Then, you just use, for example, this:</p> <pre><code>ShowMessage(GetIEVersion); </code></pre>

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.

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