How can I use Enum::GetName in unmanaged C++

Question

I am using managed extensions in VS 2008

I want to print the name of an en enum value

This code used to be fine VS 2003

Enum::GetName(__typeof(COMMAND_CODES),__box(iTmp))

but now I get a comile error

here is my enum

typedef enum  { /* Command codes */
    UMPC_NULL = 0,
    } COMMAND_CODES

Any clues ? ;

Answer 1

As far as I know, that is not possible in plain C++ since it doesn't have reflection.

You can use macros in plain C++ to workaround it:

#define COMMAND_CODES \ 
    ENUM_OR_STRING(CODE1), \ 
    ENUM_OR_STRING(CODE1),

// Enum
#define ENUM_OR_STRING(x) x
enum CommandCodes
{
    COMMAND_CODES
};
#undef ENUM_OR_STRING

// Names
#define ENUM_OR_STRING(x) #x    
char *CommandCodeNames[] =
{
    COMMAND_CODES
}; 
#undef ENUM_OR_STRING

Now the name of enum member is as easy to get as CommandCodeNames[(int)commandCode].

Can you use rtti typeid() and use the name() field?

Edit: From comment:

 Enum::GetName(COMMAND_CODES::typeid,iTmp)
