DX8 + DInput + Backward compatible???
Author
I recently installed the DX8 sdk, now my apps with Dinput code will not compile,
This is the Error
"error C2065: ''DirectInputCreate'' : undeclared identifier"
I had a look in the dinput.h file and found the following comment
/*
* To build applications for older versions of DirectInput
*
* #define DIRECTINPUT_VERSION [ 0x0300 | 0x0500 | 0x0700 ]
*
* before #include . By default, #include
* will produce a DirectX 8-compatible header file.
*
*/
I gave this a try, like so
#define DIRECTINPUT_VERSION [ 0x0300 | 0x0500 | 0x0700 ]
#include "dinput.h"
but I got the following compile error, has anyone any Idea whats going on
"c:\mssdk\include\dinput.h(145) : fatal error C1017: invalid integer constant expression"
I have my Dinput objects defined as follows
//*********************************************
//********* DINPUT ****************************
// DirectInput Objects
LPDIRECTINPUT lpDI;
LPDIRECTINPUTDEVICE lpDIDKeyboard;
LPDIRECTINPUTDEVICE lpDIDMouse;
er... it means to use one of those numbers, (the version you want to use) not the whole thing. 
#define DIRECTINPUT_VERSION 0x0500
''''A bird in hand is safer than one overhead''''
#define DIRECTINPUT_VERSION 0x0500
''''A bird in hand is safer than one overhead''''
I think youshould just replace
#define DIRECTINPUT_VERSION [ 0x0300 | 0x0500 | 0x0700 ]
by
#define DIRECTINPUT_VERSION 0x0300
or
#define DIRECTINPUT_VERSION 0x0500
or
#define DIRECTINPUT_VERSION 0x0700
depending on the version of DX you want

#define DIRECTINPUT_VERSION [ 0x0300 | 0x0500 | 0x0700 ]
by

Ahem, what the header means is:
If you want DirectInput version one:
if you want DirectInput version two:
if you want DirectInput version 7:
Rather than defining [ 0x0300 | 0x0500 | 0x0700 ].
Whoops! It's already been said three times.
Just because you're outnumbered doesn't mean you're wrong.
If you want DirectInput version one:
#define DIRECTINPUT_VERSION 0x0300#include <dinput.h> if you want DirectInput version two:
#define DIRECTINPUT_VERSION 0x0500#include <dinput.h> if you want DirectInput version 7:
#define DIRECTINPUT_VERSION 0x0700#include <dinput.h> Rather than defining [ 0x0300 | 0x0500 | 0x0700 ].
