title: Make 2nd form return input focus to 1st form in VB.net
body: <p>I’ve searched the web for an answer to this but can’t find it.  It seems a common enough issue that I’m puzzled to not find anything.</p>
  
  <p>I have 3 forms
  Form A  the form a user would be working on;
  Form B  a menu for selecting a form C to display;
  Form C  a ‘Quick List’ of data in the database to aid in entering into Form A.  There are several of these Form C's that could be displayed during a session.</p>
  
  <ul>
  <li><p>The user while working on Form A can press control-Q which will display the menu Form B.</p></li>
  <li><p>Control automatically passes to Form B where the user presses a single key and the desired Form C pops up and Form B closes.</p></li>
  <li><p>Control is passed to Form C and it is the ‘active’ form.</p></li>
  </ul>
  
  <p>There is nothing to fill in on Form C so I want to automatically return to the last active control on Form A.</p>
  
  <p>Everything works just fine but I end up with Form C as the active form.  </p>
  
  <p>How can I force control back to the last active control on Form A?</p>
