Redefinition different basic types => typedef - c++

Question

After to have been aware of the persons who had the same problem than mine, I still get this error :
error C2371: 'ST_ELLIPSE' : redefinition; different basic types
see declaration of 'ST_ELLIPSE'
C2371: 'ST_VECTEURS' : redefinition; different basic types
see declaration of 'ST_VECTEURS'
'ST_ROI' : redefinition; different basic types
see declaration of 'ST_ROI'
'ST_CONVERSION' : redefinition; different basic types
see declaration of 'ST_CONVERSION'
'ST_PARA_VISU' : redefinition; different basic types
see declaration of 'ST_PARA_VISU'

Someone would have any ideas ?
Thanks per advance for your help !

Putting #pragma once at the top of each .h file is the way to do it if you don't mind using macros, and otherwise, the 'proper' way to do it is
#ifndef AWESOME_H
#define AWESOME_H
class Awesome
{
//awesome.h contents
};
#endif
