GDI+ Bitmap class problem

I've got a strange problem. I want to load bmp file using Bitmap class from GDI+. But it's not working.

Bitmap * bmp = new Bitmap("Bitmap.bmp");

in this line I have 3 errors error C2061: syntax error : identifier 'Bitmap' error C2065: 'Bitmap' : undeclared identifier error C2065: 'bmp' : undeclared identifier I have included gdiplus.h and gdiplus.lib. What is required for using Bitmap class??
