TWebExplorer - queryCommandEnabled

I am using
WebBrowser.OleObject.Document.queryCommandEnabled('Copy') to
enable/disable the copy button on my web browser.  The problem is that this does not work with pages with frames.

It was explained to me that because the
WebBrowser.OleObject.Document is the HTML page that contains the FRAMES,
each frame contains an HTML page. So I need  to query those pages.  Possibly with something similar to

WebBrowser.OleObject.Document.Frames(i).Document.queryCommandEnabled('Copy')

where i is the frame that has focus.

The above line of code is not the exact syntax so my question is what is the
right syntax to point to the frame document for the frame that has the
focus.

Thank you.

Ok. Here is the code:
>>>>>>>>>>>>>>>
procedure TMainForm.ToolButton2Click(Sender: TObject);
var i: integer;
begin
  for i := 0 to (Viewer.OleObject.Document.frames.Length - 1) do
    if Viewer.OleObject.Document.frames.item(i).document.queryCommandEnabled('Copy') then showmessage('yes');
end;
<<<<<<<<<<<<<<<<<<<

BTW, have you tried using the DHTMLEd OCX yet? I am constantly receiving Access violations when placing it on a form. Do you experience the same?

Regards,
Freter
