title: Run macro in background
body: <p>I have some trouble with VBA macros.</p>
  
  <ol>
  <li><p>While opening a Excel file (<code>FILE1.xls</code>) which has a macro (the macro contains a userform with command buttons which i programmed it to use those command buttons as shortcuts to folders, website etc...). There is no problem with this step.</p></li>
  <li><p>I am trying to open a new Excel file (<code>FILE2.xls</code>) without macro (for example a file i received by mail) when I open the file it's invisible. I think it's a problem coming from my macro.</p></li>
  </ol>
  
  <p>So I want to run this macro in background and be able to open 6 different Excel files (for example).</p>
  
  <p>I have been searching to solve this problem for a long time.</p>
