how to add environment variables in VS2010 using .bat file?

Question

I have a batch file with this code:

@echo off
set VAR=7
echo the version is %VAR%

I want to add this .bat file to my visual studio project, using pre-build event. I wrote in the pre build event the path to the batch file, but then when I enter the : Resources ->PreProcessor definitions - I can't see the VAR How can I add it? any help would be appreciated!!

This doesn't work, unless you run everything from the batch file. When settings environment variables, this only affects the local process and doesn't change the global settings. — Bo Persson, Dec 09 '12 at 18:42

Change your BAT script to be something like

echo #define VER 7 > version.h

and then have your code use

#include "version.h"

Im sorry for the question - but it this the syntax for creating the .h file ? i should use : "#define ver 7 > version.h ? " or this sign ">" is just u showing me the direction? – user1386966 Dec 09 '12 at 19:04
The ">" says to send the output of echo to a file. – brian beuning Dec 09 '12 at 19:15
