Combining wide string literal with string macro
I have a macro for a character string as follows:
#define APPNAME "MyApp"
Now I want to construct a wide string using this macro by doing something like:
const wchar_t *AppProgID = APPNAME L".Document";
However, this generates a "concatenating mismatched strings" compilation error.
Is there a way to convert the APPNAME macro to a wide string literal?
Solution 1:
Did you try
#define APPNAME "MyApp"
#define WIDEN2(x) L ## x
#define WIDEN(x) WIDEN2(x)
const wchar_t *AppProgID = WIDEN(APPNAME) L".Document";
