Creating a new class in CodeBlocks

Hi everyone! i’m starting with OF in windows7 using CodeBlocks, so i just wanted to create a new class with

->File
->New
->Class

Then i have two new folders Sources and Headers, so i fill my classes but when i tried to build and run the project i get this error about my .h file doesn’t exist. Is there any step i’m missing when creating new classes?

Thanks

UPDATE: Nevermind just solved it. i had to change the include part on source file for something like:
#include “…/include/name_of_ur_class.h”

I’ve the same problem, have you find the problem?
