title: Opening Userform only without flashing Excel Window
body: <p>I know the method as <code>Application.Visible = False</code>  and <code>Application.Screenupdating = False</code></p>
  
  <p>When opening the file, I want the user to see <strong>only</strong> the userform. </p>
  
  <p>The thing is: with these two commands above, Excel appears for 1 second. Is it possible to do it without Excel blinking like this?</p>
  
  <p>Thanks in advance.</p>
