Which SDK is this?

This call doesn't make any sense.
You should remove it.

The correct way to do what they are trying to do is to OR
SCARD_PROTOCOL_DEFAULT with the protocols in the dwPreferredProtocols
parameter of SCardConnect.
This should only be done to resolve compatibility issues with readers
and cards allowing higher data rates.

I'm supposed to put fingerprints on smartcards. I have done this with 3
other types of cards/readers just using straight serial communications,
but
they now want me to use pc/sc. I loaded the sdk and used the vb demo
(SCrdVB) just to get started, so this is all sdk code so far. When I
checked the code I noted that the call is followed by the following
curious
catch...

    If ERROR_NOT_SUPPORTED = lngResult Then
        ' expected result, should not be able to change data rate
        lngResult = SCARD_S_SUCCESS
    End If
Any idea why they would do this? Am I going in the wrong direction?

SCardSetAttrib with SCARD_ATTR_DEFAULT_DATA_RATE is invalid (see MSDN).
What are you tring to accomplish?

But the app isn't failing, and I get no errors in the app. I just found
that I had these errors accumulating in my system event log. SCardSvr
is
throwing it, and it seems to happen when I call SCardSetAttrib using
SCARD_ATTR_DEFAULT_DATA_RATE, so you may have something there.

Thanks

    50 ERROR_NOT_SUPPORTED <--> 0xc00000bb STATUS_NOT_SUPPORTED
Is the error corresponding to this message. The error makes sense and
the message doesn't.
I believe the ioctl is IOCTL_SMARTCARD_SET_PROTOCOL
Your card probably supports higher speeds than the default 9600 and the
driver can't handle changing it.
It should only affect the performance of the app.

Since your app fails, maybe the error is bad enough that the entire
thing dies...

Winscard.dll is the SC subsystem client.
Scardssp.dll uses it (it offers some kind of abstraction layer on top of
winscard.dll)

Subject: Network request not supported errorlog entry

Hi. I have programmed a number of smartcards, but always through serial
communications. I have been tasked to use pc/sc with a gemplus 410
reader,
so I pulled the vb demo app from the sdk and it seems to run fine. I
noticed though that I have errors accumulating in my event log stating
that "smart card reader gemplus gcr410p 0 rejected ioctl ox31000c: the
network request is not supported."

Does anyone know what this means?

Also, the example uses winscard.dll. It worked fine until after I
installed the gemplus drivers, and then it failed on card calls but
still
passed on reader calls. I changed back to the microsoft driver and it
now
passes again on the card calls.

And lastly, I am able to add scardssp.dll to my vb references, but
unable
to use it as it doesn't seem compatable with vb. Does the winscard api
use
scardspp so that I can just use winscard?

Appreciate any assistance.
