title: visual studio directories and include paths
body: <p>someone please help me with this issue, i do not think i understand this clearly:</p>
  
  <p>in visual studio when i create a solution it asks me for a path where to create it</p>
  
  <p>say for the directory where to create i say  c:\work\
   and i say "sol1"  for the name of the directory.</p>
  
  <p>what i see is in c:\work\ a directory is created with name "sol1" 
   inside "sol1" there is another director "sol1" 
   and inside that i see folders like "Debug", "sol1", sol1.sln.</p>
  
  <p>now say i have some preexisting code inside c:\work\codes\code1.cpp </p>
  
  <p>i add code1.cpp to the visual sudio project "sol1" 
   adn then say i have something like #include "codes\code2.h" inside the first line of   code1.cpp</p>
  
  <p>so now how should indicate the additional include directories ? if i say something like "../.." for additional include directories what is happening. what is my reference directory starting from which other directories should be visible.</p>
  
  <p>It would be very kind of someone to clarify this issue. Please explain with a bit of detail.</p>
  
  <p>Thanks.</p>
