Tags cannot be applied to the part of text item.

You need to make the selected part of text a separate item.

It can be done by applying some different text style to the selection (I

hope, hyperlinks have a special text style in your program) - call

ApplyTextStyle before the cycle SetItemTag.

Note 1:

It's better to use the following function for obtaining stno and enno:

procedure GetSelectionBounds(rve: TCustomRichViewEdit;

  var StartNo, EndNo: Integer);

var StartOffs, EndOffs: Integer;

begin

   rve.RVData.GetSelectionBoundsEx(StartNo, StartOffs, EndNo, EndOffs,

True);

   if (StartNo<>EndNo) or (StartOffs<>EndOffs) then begin

     if StartOffs>=rve.GetOffsAfterItem(StartNo) then

       inc(StartNo);

     if EndOffs<=rve.GetOffsBeforeItem(EndNo) then

       dec(EndNo);

   end;

end;

Note 2: It's better to use SetItemTagEd, and undo grouping.
