I'm trying to create a directinput object and then creating a keyboard object. All fine, but the linker is giving 'unresolved reference' errors. I've included some code:

bool DirectInputInit(){
HRESULT dirval;
dirval = DirectInputCreate((HINSTANCE)GetWindowLong(windowhandle,GWL_HINSTANCE), DIRECTINPUT_VERSION, &lpDI, NULL);
if( dirval != DI_OK) return(false);
dirval = lpDI->CreateDevice(GUID_SysKeyboard,&lpKeyboard,NULL);
if( dirval != DI_OK) return(false);
dirval = lpKeyboard->SetDataFormat(&c_dfDIKeyboard);
if( dirval != DI_OK) return(false);
dirval = lpKeyboard->SetCooperativeLevel(windowhandle,DISCL_EXCLUSIVE | DISCL_FOREGROUND);
if( dirval != DI_OK) return(false);
lpKeyboard->Acquire();
return(true);
};

This may be a silly answer, but did you try linking with dinput.lib?

Yes, I did.
The compiler only moans about UID_SysKeyboard and GUID_SysKey.

To use GUID, you also need to include
dxguid.lib
and you need to
#define INITGUID

bosjoh,
Are you perhaps using the DX7 borland libs? I know that during the beta, the lib's had an error in them. They should be fine now. Did you upgrade to DX7 gold?

Nope, using VC++ 6.0 libs.
Is this upgrade also available for VC++ 6.0?
I hope it isn't 128 MB (!)

bosjoh,
When I said DX7 gold, I meant the RTM. If you have the final version, you should be fine.

You do not need to include the dxguid.lib
AND #define INITGUID as stated above. Just #define INITGUID would do in most cases. Adding the lib would only increase the size of your exe-file. Try without the lib, if it works then, do not use it.

I'll try it.
