I update my Opencv 2.4.2 to Opencv 2.4.3 , some of my programs works well with opencv2.4.2 ，but they could not run with opencv2.4.3. It shows that it could not find some Macros such as MAX_PATH M_PI and,I am sure that I add corret corresponding head file，How could I solve these problems？

If I understand right, you use Windows and Visual Studio. Add the following includes at the beginning of source code:

#include <windows.h>
#define _USE_MATH_DEFINES
#include <math.h>
