I have this function where I open my internet explorer with a url. I need to detect if my internet explorer was closed and then allow my function create a new call, if it is not closed, I just send the new url to it. How can I check this once I have the handle kept?

function OpenIE(url: string; ie: IWebBrowser2): IWebBrowser2;

  Flags, TargetFrameName, PostData, Headers: OleVariant;
  if Not Assigned(ie) then
    // Uses ComObj + SHDocVw_TLB
    ie := CreateOleObject('InternetExplorer.Application') as IWebBrowser2;
    //  SetParent(ie.HWND, form1.Handle);
    ie.Left := (Screen.Width - 750) div 2;
    ie.Top := (Screen.Height - 560) div 2;

    ie.Width := 750;
    ie.Height := 560;
    ie.MenuBar := false;
    ie.AddressBar := false;
    ie.Resizable := True;
    ie.StatusBar := false;
    ie.ToolBar := 0;

    ie.Visible := true;
  End Else

  result := ie;

Open in new window
