Thanks, BdLm.
I did this, but the new web page was not displayed in the new tabsheet. Instead a new IE was launched with the new web page.
Could you help?
Thank you in advance.

procedure TForm3.IE6NewWindow2(Sender: TObject; var ppDisp: IDispatch; var Cancel: WordBool);
var
  mTabSheet: TTabSheet;
  mWebBrowser: TWebBrowser;
begin
  mTabSheet := TTabSheet.Create(PageControl1);
  mTabSheet.Caption := 'blank';
  mTabSheet.Name := 'tsNewPage_' + FormatDateTime('yyyymmddhhnnsszzz', now); // just a unique name
  mTabSheet.PageControl := PageControl1;
  mTabSheet.Parent := PageControl1;
  PageControl1.ActivePage := mTabSheet;
  mWebBrowser := TWebBrowser.Create(mTabSheet);
  mTabSheet.InsertControl(mWebBrowser);
  TWinControl(mWebBrowser).Name := 'WB_' + FormatDateTime('yyyymmddhhnnsszzz', now); // just a unique name
  TWinControl(mWebBrowser).Parent := mTabSheet;
  mWebBrowser.Align := alClient;

You have to set the ppDisp to point to the new webbrowser.
Something like this...
ppDisp := mwebBrowser.ControlInterface;

Don't forget to add this line, too, so the new window will do the same thing:
  mWebBrowser.OnNewWindow2 := IE6NewWindow2;

Oh, and another thing, make sure you destroy the new webbrowser instances and TTabSheets
when closing your form.
