YES!!! I know the problem....


That book uses direct input code for Dx5.0 i think.

BUT If you have the 8.0 api installed the code won''t compile.

You need to update the code for directx8.0

Here is some code that I updated for Windows Programming for dumbies" which uses a lot of the same code from "Gurus"
I think this is all hyou will need to change... My function names may be slightly different. ALso you may need to change a little more of the other functions but I can''t remember if you do. This should get you started


//globals

LPDIRECTINPUT8 lpdi; // dinput object
LPDIRECTINPUTDEVICE8 lpdikey; // dinput keyboard
LPDIRECTINPUTDEVICE8 lpdimouse; // dinput mouse
LPDIRECTINPUTDEVICE8 lpdijoy2; // dinput joystick


//functions

int DInput_Init(void)
{
// this function initializes directinput

if (DirectInput8Create(main_instance,DIRECTINPUT_VERSION,IID_IDirectInput8,(void**)&lpdi,NULL)!=DI_OK)
return(0);

// return success
return(1);

} // end DInput_Init

int DI_Init_Joystick(int min_x, int max_x, int min_y, int max_y)
{
// this function initializes the joystick, it allows you to set
// the minimum and maximum x-y ranges

// first find the fucking GUID of your particular joystick
lpdi->EnumDevices(DI8DEVCLASS_GAMECTRL,
DI_Enum_Joysticks,
&joystickGUID,
DIEDFL_ATTACHEDONLY);

if (lpdi->CreateDevice(joystickGUID, &lpdijoy2, NULL)!=DI_OK)
return(0);


// set cooperation level
if (lpdijoy2->SetCooperativeLevel(main_window_handle,
DISCL_NONEXCLUSIVE | DISCL_BACKGROUND)!=DI_OK)
return(0);

// set data format
if (lpdijoy2->SetDataFormat(&c_dfDIJoystick2)!=DI_OK)
return(0);


// set the range of the joystick
DIPROPRANGE joy_axis_range;

// first x axis
joy_axis_range.lMin = min_x;
joy_axis_range.lMax = max_x;

joy_axis_range.diph.dwSize = sizeof(DIPROPRANGE);

joy_axis_range.diph.dwObj = DIJOFS_X;
joy_axis_range.diph.dwHow = DIPH_BYOFFSET;

lpdijoy2->SetProperty(DIPROP_RANGE,&joy_axis_range.diph);

// now y-axis
joy_axis_range.lMin = min_y;
joy_axis_range.lMax = max_y;

joy_axis_range.diph.dwSize = sizeof(DIPROPRANGE);
joy_axis_range.diph.dwHeaderSize = sizeof(DIPROPHEADER);

// acquire the joystick
if (lpdijoy2->Acquire()!=DI_OK)
return(0);

// set found flag
joystick_found = 1;

// return success
return(1);

} // end DI_Init_Joystick

BOOL CALLBACK DI_Enum_Joysticks(LPCDIDEVICEINSTANCE lpddi,
LPVOID guid_ptr)
{
// this function enumerates the joysticks, but
// stops at the first one and returns the
// instance guid of it, so we can create it

*(GUID*)guid_ptr = lpddi->guidInstance;

// copy name into global
strcpy(joyname, (char *)lpddi->tszProductName);

// stop enumeration after one iteration
return(DIENUM_STOP);

} // end DI_Enum_Joysticks

int DI_Read_Joystick(void)
{
// this function reads the joystick state

// make sure the joystick was initialized
if (!joystick_found)
return(0);

if (lpdijoy2)
{
// this is needed for joysticks only
if (FAILED(lpdijoy2->Poll()))
{


return(0);
}


if (FAILED(lpdijoy2->GetDeviceState(sizeof(DIJOYSTATE2), (LPVOID)&joy_state)))
return(0);
}
else
{
// joystick isn''t plugged in, zero out state
memset(&joy_state,0,sizeof(joy_state));

// return error
return(0);

// return sucess

} // end DI_Read_Joystick

lets try this again:

Yup...

Sorry about that parklife... I forgot about dinput8.dll

D''OH!!!!!!!!!!


Anyway... The code for the other devices (mouse and keyboard)should work just fine. I think they changed DI for DX8 to support the XBOX controllers and other more complex joysticks that may come out in the future (just a guess though)
