help me! im trying to initalize a DirectInput object and i get this darn error i dont know what to do with, i think it may have somthing to do with using dx7 but having dx8... i dont konw... please help... and any more info you need, just ask code is in c++ -------CODE that i think is the problem: // Create our DirectInput object if ( FAILED(hr = IDirectInputDevice8(hInst, DIRECTINPUT_VERSION, IID_IDirectInput7, ( void ** )&lpDI, NULL ) ) ) return hr; -------MSVC compile time errors: --------------------Configuration: Version F Monkey - Win32 Debug-------------------- Compiling... monkey.cpp c:\directxsdk\include\dinput.h: DIRECTINPUT_VERSION undefined.

Ooooo, i fixed it! but after fixing it ( by defining DIRECTINPUT_VERSION to 0x0700 before including dinput.h)i got another error

if anyone would be so generous as to help me, this is what it spat out at me:

hmmm... i have determined that it has something to do with the whole GUID unique identifier thing... what exactly i am yet to determine, i still dont quite understand it

You need to create a directinput8 object. With that you can then create direct input devices.

pseudo code:

LPDIRECTINPUT8 lpdi;
LPDIRECTINPUTDEVICE8 lpdid;


DirectInput8Create(application instance, DI version, DI interface guid, &lpdi, NULL);

lpdi->CreateDevice(device guid, &lpdid, NULL);

I''m shit at explaining things. I could just send you the code to my input subsystem. Let me know if this would help.

eb.

Frik! computer crashed so i lost my post. short version is as follows:

i still dont really understand but please send the code to me, i think it will help me out tonnes. my email is nobody_91@hotmial.com

please and thanks

ok, well my program was giving me too much hassle so i scraped the whole thing and started again. the aformentioned problems are nolonger applicable however, new ones have arisen. i found a directinput tutorial on MSDN that helped me alot this time, basicly all i have had to do is cut and paste code.

this is my current probelm if anyone cares to help:

my program will compile just fine without error, but when i go to build (or link or whatever it is called) it i get this:

--------------------Configuration: Version F Monkey - Win32 Debug--------------------
Linking...
monkey.obj : error LNK2001: unresolved external symbol _c_dfDIKeyboard
monkey.obj : error LNK2001: unresolved external symbol _DirectInput8Create@20
Debug/Version F Monkey.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

Version F Monkey.exe - 3 error(s), 0 warning(s)


i have no idea why i get this or how to fix it. please help
