title: visual studio 2010 c++ debugging symbols loaded but can't find source code
body: <p>I've specified symbol (pdb) file inside 2010 so that it is loaded correctly but I get the <code>No source available</code> error and the <code>Browse to Find Source Code</code> is greyed out. Does anyone know how I can specify the source code directory or look inside the pdb to find out where it is? </p>
  
  <p>EDIT: My DLL is being called by an external program. The error is happening inside my DLL so I  have the source code. When the error occurs I click Debug, the pdb symbols are loaded but not the source. </p>
