title: Header files included in stdafx.h are not found
body: <p>i'm using visual studio 2008. I include some includes ( boost headers ) in the stdafx.h but, now they arent found by the compiler ( lexical_cast not found for example ). I included stdafx.h on the top of the cpp file. So what i'm doing wrong?</p>
  
  <p>Thank's in advance</p>
  
  <p>edit:: i've set the include path correctly, if i'm including the boost header in the cpp -file directly, everything works.</p>
