You can drop a TWebBrowser on your form, you will then have to import the MS HTML control Type Library (Do you know how to do this?)

Use the code below to get to the document

procedure TForm1.Button1Click(Sender: TObject);
var
 Document: IHTMLDocument2;
begin
 WebBrowser1.Navigate('Your Url Here');
 Document:= WebBrowser1.Document as IHTMLDocument2;
end;

From here I can help you get to a particular Form Eleement - do ou know its name or ID?

bbh2k3, after some testing, I found that the MS HTML Object Type Library has
a interface (IHTMLSelectElement) which you can use to get to your dropdown box


procedure TForm1.Button1Click(Sender: TObject);
var
 aHTMLDoc : IHTMLDocument2;
 vControl : IHTMLSelectElement;
 S: String;
begin
if not VarIsEmpty(WebBrowser1.Document) then
 begin
   aHTMLDoc := WebBrowser1.Document as IHTMlDocument2;
   vControl:= aHTMLDoc.all.item('NameEdit', 0) as IHTMLSelectElement;
   {vControl.length; //number of items in dropdown}
   {vControl.selectedIndex //index of selected item}
   {vControl.item() //retrieve particular item}
 end;
end;
