I have them all, but I don't believe most of them are available. If you
have a MSDN subscription, you can find some in the downloads area. HID is
not my area, but maybe Doron knows. I think it may be very difficult to
find what you are looking for. Why not use the free Visual Studio 2008?
That may work better for you. Some things may be missing from that version,
so I am not sure it can be made to work. With the latest SDK/WDK and the
free one you may have a chance.

Thanks for the quick reply, unfortunately you gave the answer i expected
and
feared.
Is there anywhere i can get an older VC++ 6 compatible version of WDK or
is
there any other way of doing low level communications with a HID USB
device
or is upgrading the only way now?

VC6 is too old. Many of the headers in the current WDK will not compile

available in a compiler that old. Use VC6 only as an editor - if you
must,
but never to compile code based upon any current WDK.

Hi all,
I was advised here
(http://social.msdn.microsoft.com/Forums/en-US/vcgeneral/thread/af92144a-2c7d-4d0c-b420-11385527e7b5)
that this would be the place to ask, so if i've got it wrong again
sorry.
I'm tasked with writing an application to communicate with a USB card
reader
(HID device) and a Barcode scanner, we use Visual Studio 6, so i could
do
this in VB6 if it might be easier but the rest of the application is in
VC++
(and it's what i know best allegedy). The application needs to be able
to
detect when the device is present and plugged in as well as being able
to
send and receive USB reports (so i'd say i'm writing a driver for the
readers
as well) to query the device's status. From what i gather the functions
i
want to be able to use are in the hid.dll library. But i'm confused
about
the
whole DDK thing, various places have said that you shouldn't and can't
use
the VC++ environment with these functions, but I find it hard to
believe
that
with the header and libraries that i cannot use these functions
(HidD_GetHidGuid() to name one) from the dll in a VC++ app. I've been
trawling around the net for ages without much luck getting increasingly
frustrated and confused.
I have followed instructions from the book USB complete to the letter
and
still i am unable to get the app to compile.
Anyway enough moaning about it here is what i have done:
1) Create a new MFC application within VC++
2) gone to Project > Settings > Link > Category: Input and In the
Object/library modules box entered hid.lib and setupapi. lib.
3) added the correct directory to the Additional library path field
4) included the correct header files:
extern "C" {
#include "hidsdi.h"
#include <setupapi.h>
}
5) Finally added a call to the function into my application in the
InitInstance() function like so:
GUID HidGuid;
HidD_GetHidGuid(&HidGuid);
6) hit compile and got a whole load of errors:
c:\winddk\6001.18002\inc\api\hidpi.h(514) : error C2065: '__in' :

identifier
c:\winddk\6001.18002\inc\api\hidpi.h(514) : error C2146: syntax error :

c:\winddk\6001.18002\inc\api\hidpi.h(630) : error C2059: syntax error :
')'
(thats not all of them, but enough to illustrate the point i hope).
So the question is how do i import HidD_GetHidGuid() (or any function
from
hid.dll) into my application successfully?
I know it can be done as i downloaded some demonstration HID source and
pointed it at the headers and libraries and it worked for a bit until i
tinkered too far and ended up with the same result and i cannot
remember
how
i got this demo to work.
Please ask for more information if you need it to help me.
Kind Regards,
JQ
