It works !!! Hooray.... Looks just like what I wanted - this is damn
exciting... Time to read the wdf-ramdisk code in detail :)

Just curious - what is this wdfCoInstaller ? Some kind of support lib for
all wdf drivers ? Can I get the source code for this one too ?

Thanks a lot.

regards,
Hassan

I have installed KMDF and I compiled the ramdisk sample without any
issues
(windows xp checked build).

However when I try to install the device driver I get the following
error
during installation:
wdfcoinstaller01001.dll missing (and a popup dialog opens up and asks
me
to
locate the file - I couldn't find it within the KMDF directory). I
checked
the ramdisk.inf - this wdfcoinstaller01001.dll is there as part of the
coInstaller (and it seems to be part of a 11 file group). I guess I
have
missed something... Can someone please tell me what am i doing wrong ?
I
have
even tried to install the driver by commenting out the coInstaller part
of
the ramdisk.inf file - still no success...

Thanks for the help so far...

regards,
Sh@h

actually, download KMDF
http://www.microsoft.com/whdc/driver/wdf/KMDF_pkg.mspx and use the
KMDF
version of ramdisk. it has been updated and bugs have been fixed.
