Hi,
I am trying to install Passthru driver on Windows CE .NET 4.2. Is there any
documentation online which I can follow to get the Passthru code running on
WinCE platform?
Thanks in adavance for your help and time.

Niranjan,
The short answer is no. There is not much online or documented (outside of
the PASSTHRU sample) on how to install an IM driver on Windows CE.
The sample PASSTHRU included with CE.NET 4.2 Platform Builder does include a
file with the necessary registry settings to start the driver.
The source also includes some very important CE specific code to deal with
bindings. I recommend that you look at that code very carefully. Managing
the binding process in an IM driver for CE is particularly important since
the OS does not provide anything like INetCfg or NetDi to help.
You should also be aware that the Pocket PC platforms are particularly
tricky to get an IM drive operating correctly on. A custom CE.NET platform
may or may not have similar issues (depending on the OS features & design).
If you do not have Platform Builder, you will need to get it (or at least
the ‘community release’ version that is an eval) to access the CE specific
PASSTHRU sample. I recommend reading it carefully and also reading and
understanding the differences in the Windows DDK versions of PASSTHRU
starting with the Win2K DDK all the way through the 2K3 DDK. Updates and
additional insight into IM driver behavior have been added at various times.
The CE.NET sample has not always been kept in line. The CE.NET 5.0 Platform
Builder might be an additional resource (a download version, I believe, is
still available as well).
One thing to keep in mind (that is quite a departure from NT5) is that a
protocol (or IM driver protocol edge) in CE.NET will be called to bind at
ProtocolBindAdapter() with just about every NDIS Miniport in the system.
That includes NDISWAN miniports like PPTP, L2TP, and ASYNCMAC as well as
IRDA miniports. Your bind handler needs to pay close attention to filtering
out these (I assume) unwanted bind opportunities.
Another issue is that an IM driver (at least a filter driver) expects to
have an exclusive binding on the protocol edge. Achieving this in a
reliable way on CE (dynamically) is a bit of a trick. I believe you will
find that the PASSTHRU sample has a few hints but not quite a complete or
robust solution.
Good Luck,

Thanks David for your excellent reply.
I have got the passthru driver compiled for Windows CE platform using
Platform Builder 4.2 and have copy it to the PDA.
But I didn’t find any documentation regarding registry settings I need to
make to install passthru driver on Windows CE platform. Can anybody please
help me in this regard?
Thanks,
-Niranjan
