{ To test this code put a TWebBrowser and A TButton component on the form }


 function FillForm(WebBrowser: TWebBrowser; FieldName: string; Value: string): Boolean;
  var

  //For example you can load the page /en/addtip.php to the TWebBrowser  
//When the document is Complete the form where you can put your homepage  
//address is filled out  
procedure TForm1.Button1Click(Sender: TObject);
  begin
    Webbrowser1.Navigate('http://www.swissdelphicenter.ch/en/addtip.php');
    // Show the Titel of the currently active Webpage in the titlebar  
  // Den Titel der aktuellen Webseite in der Titeleiste anzeigen  
  Caption := Webbrowser1.OleObject.Document.Title;
