GDI+ makes use of WCHAR instead of what the WinAPI allows which is CHAR. Usually I can do:
char *str = "C:/x.bmp";
but how do I do this for wchar? I can't juse do
wchar_t *file = "C:/x.bmp";
Thanks

wchar_t *file = L"C:/x.bmp";
L introduces a wide string.
In Windows, it's customary to use macros that behave differently according to some preprocessor definitions. See http://msdn.microsoft.com/en-us/library/c426s321(VS.71).aspx
You would write:
_TCHAR *file = _TEXT("C:/x.bmp");

const wchar_t *file = L"C:/x.bmp";
This is according to C++ Standard 2.13.4/1:
<...>A string literal that begins with L, such as L"asdf", is a wide string literal. A wide string literal has type “array of n const wchar_t” and has static storage duration, where n is the size of the string as defined below, and is initialized with the given characters.
Note that you should use const
qualifier here. The effect of attempting to modify a string literal is undefined (2.13.4/2).
