Seems really odd to me that to use gdiplus, you have to have:#ifndef ULONG_PTR #define ULONG_PTR unsigned int#endifbefore the:#include and that the ULONG_PTR is not defined in that header as gdiplus uses that syntax.Weird. I wonder if that MS define is in like windows.h or something.

Yes, turns out that is defined if you include windows.h (although it's really defined in a header called into windows.h).Case anyone was interested.
