title: importing a lib file using visual studio
body: <p>I am trying to import a file as below:</p>
  
  <pre><code>#import "francais.dll"
  </code></pre>
  
  <p>It says to me that it cannot open source file "C:/xxxx/Proj/Release/francais.tlh"</p>
  
  <p>The Library file is existing in Proj.</p>
  
  <p>How to solve that?</p>
