title: Rebuild precompiled header
body: <p>I am trying to use MFC with ProC.<br/>
  Functions.pc is where I do the ProC syntax to connect to the database. So I include the <code>'Functions.h'</code> in the dialog model where I want to call the functions in <code>'Funtions.h'</code>. And now I got this error.</p>
  
  <pre><code>    Add directive to 'stdafx.h' or rebuild precompiled header
  </code></pre>
  
  <p>I understand that I need to include <code>'stdafx.h'</code> to <code>'Functions.h'</code> for it to work. And I did that. It can compile,but then when I try to run the program,it won't recognize the syntax of ProC created by the <code>'Functions.cpp'</code> created. I don't really understand how to rebuild the precompiled header since I don't understand the codes in <code>'stdafx.h'</code>.</p>
