You should send this message to a device ID instead of a device handle.

Has anyone tried sending the DRV_QUERYDEVICEINTERFACESIZE message to a
wave
device?  I tried using it (and its companion, DRV_QUERYDEVICEINTERFACE)
on
two Windows XP systems (one "Gold", one SP1), and they both seem to
return
MMSYSERR_NOTSUPPORTED (8).  Both devices queried used WDM Audio drivers;
one
driver was signed and one driver was not signed.  I tried both wave in
and
wave out devices.

Any ideas?  A fragment from my test program is pasted below.  I am
probably
missing something obvious.

Best regards,
-Dan
