having trouble with dinput.h

Hi

I started implementing direct input into my program for the first time and started recieving a bunch of link errors while I have dinput.h included. NOTE: I have made the neccissary changes according to your sticky thread about BASETSD.H to fix compatability issues with visual C++ 6.

these are the errors i recieve:

any ideas as to what I did wrong? i'm kinda stumped since msdn says al these things are apart of the dinput library.

thanx in advance
Boomba,

Well the first error is happening because you must define DIRECTINPUT_VERSION.

Code:

---

#ifndef CDINPUT
#define CDINPUT
 
//You MUST define this PRIOR to including dinput.h
#define DIRECTINPUT_VERSION 0x0800
#include <dinput.h>
 
 
 
 
class CDInput
{
protected:
IDirectInput8 *_pDI8;
public:
CDInput() { };
                CDInput(HINSTANCE hinst) {Init(hinst);};
~CDInput() { };
 
HRESULT Init(HINSTANCE hinst);
                void ShutDown(void) {if (_pDI8) _pDI8->Release();};
                IDirectInput8 *GetInterface(void) {return _pDI8;};
};
#endif

The second error is happening because...I think....since you have not defined DIRECTINPUT_VERSION it is not sure which library to link with ---------- OR you are not correctly linking with dinput.lib or dinput8.lib. I had to link with both dinput8.lib and dinput.lib to get my code to work correctly.

Trust me I was so frustrated with DirectInput when I created my classes I wished I had never ever heard of the thing. I ran into the same errors you did on my first try.

thank you very much Bubba! that got rid of all the link errors :D
