I am 99 % sure that such a function does not exist in the RTL (as of Delphi 2009). Of course - however - it is trivial to write such a function. Update HTTPUtil.HTMLEscape is what you are looking for: <pre><code>function HTMLEscape(const Str: string): string; </code></pre> I don't dare to publish the code here (copyright violation, probably), but the routine is very simple. It encodes "<", ">", "&", and """ to <code>&lt;</code>, <code>&gt;</code>, <code>&amp;</code>, and <code>&quot;</code>. It also replaces characters #92, #160..#255 to decimal codes, e.g. <code>&#92;</code>. This latter step is unnecessary if the file is UTF-8, and also illogical, because higher special characters, such as ∮ are left as they are, while lower special characters, such as ×, are encoded. Update 2 In response to the answer by Stijn Sanders, I made a simple performance test. <pre><code>program Project1; {$APPTYPE CONSOLE} uses Windows, SysUtils; var t1, t2, t3, t4: Int64; i: Integer; str: string; const N = 100000; function HTMLEncode(const Data: string): string; var i: Integer; begin result := ''; for i := 1 to length(Data) do case Data[i] of '<': result := result + '&lt;'; '>': result := result + '&gt;'; '&': result := result + '&amp;'; '"': result := result + '&quot;'; else result := result + Data[i]; end; end; function HTMLEncode2(Data: string):string; begin Result:= StringReplace( StringReplace( StringReplace( StringReplace( Data, '&','&amp;',[rfReplaceAll]), '<','&lt;',[rfReplaceAll]), '>','&gt;',[rfReplaceAll]), '"','&quot;',[rfReplaceAll]); end; begin QueryPerformanceCounter(t1); for i := 0 to N - 1 do str := HTMLEncode('Testing. Is 3*4<3+4? Do you like "A & B"'); QueryPerformanceCounter(t2); QueryPerformanceCounter(t3); for i := 0 to N - 1 do str := HTMLEncode2('Testing. Is 3*4<3+4? Do you like "A & B"'); QueryPerformanceCounter(t4); Writeln(IntToStr(t2-t1)); Writeln(IntToStr(t4-t3)); Readln; end. </code></pre> The output is <pre><code>532031 801969 </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.
