CeRapiInvoke in librapi2-0.13

Hey,
I have been trying to get CeRapiInvoke to work. Just using the unit
tests in the release. All I get is -2147467263 as a return result.

0x80004001 means "not implemented"

Is CeRapiInvoke implemented? Is it still only Stream mode?

UTSL :-)
Unfortunately it has not been implemented for Windows Mobile 5 or newer
devices. Any takers on the synce-devel list?

Thanks for your time,
Rob

Rob, I'll take a look at this sometime, but my time is very limited at
the moment, so I'll need three things, the dll you're using on the
device and the code you're using to call it, and the command code for
CeRapiInvoke on WM5 :) I don't have anything set up to generate the call
on Windows to capture that code, so someone will have to find it for me.

The more I think about this, the more I suspect that the CeRapiInvoke on
WM5 is more complicated than knowing the command code and that's why the
command code is not documented in
https://synce.svn.sourceforge.net/svnroot/synce/trunk/librapi2/src/rapi2/README.

I would need a few reverse engineering hours to confirm this though...

I believe Rob was trying to execute the test located at
http://synce.svn.sourceforge.net/viewvc/synce/trunk/librapi2/tests/CeRapiInvoke/which
has a DLL with it.

If someone can briefly explain how I would go about getting the command code
for CeRapiInvoke on WM5, I have the necessary hardware and time.

Yes, I was referring to the dll invokeme.dll. I have also tried making
my own in Visual Studio.

Ah yes, I've never noticed that there !

If someone can briefly explain how I would go about getting the
command code for CeRapiInvoke on WM5, I have the necessary hardware
and time.

Theoretically, run a small program on a windows host that just
RapiInit's and calls the command we're interested in, and capture the
transmission on the network interface using eg. wireshark.

Of course, being MS it's rarely that straightforward, and if David is
correct it could be a lot more complex. However, if you could use the
test prog for CeRapiInvoke from windows and capture everything over the
interface, we might be fortunate.

I don't have anything set up to generate the call

I'm calling
hr = CeRapiInvoke("\\invokeme.dll", "PingBuffer", PING_BUFFER_SIZE, buffer,
&output_size, &output_buffer, NULL, 0);

with PING_BUFFER_SIZE = 10

I've attached the wireshark pcap. Ignore everything before 12 seconds. I
called the identical invoke 3 times on the device. buffer should be 10
0xDD's. output_buffer and output_size were uninitialized and when finished
output_buffer is identical to buffer and output_size is 10
(PING_BUFFER_SIZE).

I'm not sending this to hand it off to you guys. I'm still looking at this
myself to see if I can implement it or figure out the command code, but I'm
sure the people on this list have more experience doing this.

Let me know if you have any questions or want me to redo with some changes.

I called CeCreateFile("//test.txt", GENERIC_READ | GENERIC_WRITE, 0, NULL,
OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL); and watched that connection on
wireshark so I had some basis for comparison.

CeCreateFile has a command code of 0x16 and using this knowledge I believe
the command code for CeRapiInvoke is 0x4C on WM5. (Which according to
https://synce.svn.sourceforge.net/svnroot/synce/trunk/librapi2/src/rapi2/READMEis
already taken by CeSetDatabaseInfoEx which is troubling, I think)

I've attached the log of CeCreateFile in case someone wants to double check
my work or like me finds it easier to compare the two side-by-side.

My amateur opinion is that CeCreateFile and CeRapiInvoke look really similar
on the wire and is hopefully not hard to implement for that reason. I'll
try my hand at it today.

David, the trace of the call sent to the device looks good. It actually
looks exactly like what rapi1 invoke would send apart from the command
code, which should make life easier.

I can't see the data being sent back however. The data returned from the
first call (packet 16) looks like this

0c 00 00 00 data len = 0x0c = 12
7e 00 00 00 error mod not found
7e 00 07 80
00 00 00 00

which would suggest it can't find the dll. Is the path correct in your
call ?

As for code 0x4c being assigned to CeSetDatabaseInfoEx, none of the
database functions for rapi2 have been implemented. Maybe David (E) can
give some indication of how reliable that list is ?

I implemented reading of the output_size and output_buffer too. I couldn't
figure out how to actually run the CeRapiInvoke tests (my automake
experience is lacking) but I did create a separate executable that does the
same thing as those tests. It should pass test_ping_result and
test_ping_buffer now, but not the stream test (will still return
E_NOTIMPL). I didn't check test_last_error yet.

https://synce.svn.sourceforge.net/svnroot/synce/trunk/librapi2/src/rapi2/READMEis already taken by CeSetDatabaseInfoEx which is troubling, I think)

exactly the same as the old invoke.
I'll implement the reading of output_size and buffer today and send a
patch. I'm not going to look into stream mode at this time, but may in the
future.
Thanks for all the help!

Sometimes I wonder why I spend so much time writing software that deals
with MS rubbish :)
Can't invoke on WM5+ because it's in 'RAPI Restricted Mode', anyone know
how to switch to 'Open Mode' ?

I'm not encountering this problem. I'm guessing its because I disabled all
security in Visual Studio for the device.

Post by David Richardson
I've attached the wireshark pcap. Ignore everything before 12
seconds. I called the identical invoke 3 times on the
device. buffer should be 10 0xDD's. output_buffer and
output_size were uninitialized and when finished output_buffer
is identical to buffer and output_size is 10
(PING_BUFFER_SIZE).
I'm not sending this to hand it off to you guys. I'm still
looking at this myself to see if I can implement it or figure
out the command code, but I'm sure the people on this list
have more experience doing this.
Let me know if you have any questions or want me to redo with
some changes.

Hey,
I have been trying to get CeRapiInvoke

to work. Just using

the unit

tests in the release. All I get is

-2147467263 as a return

result.

0x80004001 means "not implemented"

Is CeRapiInvoke implemented? Is it still

only Stream mode?

UTSL :-)
Unfortunately it has not been implemented

for Windows Mobile

5 or newer

devices. Any takers on the synce-devel

list?

Thanks for your time,
Rob

Best regards,
David Eriksson,

http://www.divideandconquer.se/

Rob, I'll take a look at this sometime, but

my time is very

limited at
the moment, so I'll need three things, the

dll you're using on

the
device and the code you're using to call it,

and the command

code for
CeRapiInvoke on WM5 :)
I believe Rob was trying to execute the test located

http://synce.svn.sourceforge.net/viewvc/synce/trunk/librapi2/tests/CeRapiInvoke/which has a DLL with it.

Post by David Richardson
Ah yes, I've never noticed that there !

If someone can briefly explain how I would go about

getting the

command code for CeRapiInvoke on WM5, I have the

necessary hardware

and time.

Theoretically, run a small program on a windows host
that just
RapiInit's and calls the command we're interested in,
and capture the
transmission on the network interface using eg.
wireshark.
Of course, being MS it's rarely that straightforward,
and if David is
correct it could be a lot more complex. However, if
you could use the
test prog for CeRapiInvoke from windows and capture
everything over the
interface, we might be fortunate.

I don't have anything set up to generate the

call

on Windows to capture that code, so someone

will have to find

it for me.
Mark

I implemented reading of the output_size and output_buffer too. I
couldn't figure out how to actually run the CeRapiInvoke tests (my
automake experience is lacking) but I did create a separate executable
that does the same thing as those tests. It should pass
test_ping_result and test_ping_buffer now, but not the stream test
(will still return E_NOTIMPL). I didn't check test_last_error yet.

Hi David, thanks for the patch. I'd like to do some work on the rest of
it, but I do linux programming, not MS :) I've got a trial version of
Visual Studio around somewhere, can you explain how to disable the
device's security from there ?

I'm calling
hr = CeRapiInvoke("\\invokeme.dll",

"PingBuffer",

Post by David Richardson
PING_BUFFER_SIZE, buffer, &output_size,

&output_buffer, NULL,

Post by David Richardson
0);
with PING_BUFFER_SIZE = 10

David, the trace of the call sent to the device

looks good. It actually

looks exactly like what rapi1 invoke would send

apart from the command

code, which should make life easier.
I can't see the data being sent back however. The

data returned from the

first call (packet 16) looks like this
0c 00 00 00 data len = 0x0c = 12
7e 00 00 00 error mod not found
7e 00 07 80
00 00 00 00
which would suggest it can't find the dll. Is the

path correct in your

call ?

I noticed that as well. Check out this pcap file. I'm
calling PingResult this time and you can actually see the data
being returned. PingResult takes a value and returns it as a
the return code. I'm passing in 0x12345678. I'm trying to
take it one step at a time and just trying to get the return
code and error code to be valid before I worry about reading
the output_size and output_buffer. I've got that working.
You're right, its pretty much exactly the same as the old
invoke.
I'll implement the reading of output_size and buffer today and
send a patch. I'm not going to look into stream mode at this
time, but may in the future.
Thanks for all the help!

As for code 0x4c being assigned to

CeSetDatabaseInfoEx, none of the

database functions for rapi2 have been implemented.

Maybe David (E) can

give some indication of how reliable that list is ?

The first step is to get it detected by ActiveSync. If you're using a VM
like I am, you're unlikely to get RNDIS to connect, so disable advanced
networking. Once it is detected fire up VS and Tools > Device Security
Manager... > Connect to a device...

Platform: Windows Mobile 5.0 Pocket PC SDK
Devices: Windows Mobile 5.0 Pocket PC Device R2

Hit connect and be ready to hit "Yes" to about 5 dialog boxes on the
device. Afterwards click "Security Off" and then "Deploy to Device".

You probably need the WM SDK to do this (maybe included, depending on your
trial).

Installing SdkCerts.cab may do the trick, too. I'm also a Linux developer
and would love to cut the Visual Studio step out of my development.

David Richardson

Also this patch has a minor bug fix (wasn't actually responding with the
number of bytes in the output, but just synce_tracing the value).

Cool, I've now managed to disable the security on my device to test
this, and have now committed your second patch with a couple of tweaks.
I couldn't decide from the documentation whether pcbOutput was allowed
to be NULL, but since one of the tests passes in NULL I've put in a
check for it. The tests all now pass except for using a stream
obviously.

I previously committed a patch to build the invoke test, so if you use
the source from svn you won't need your other test executable.

As for cutting out the Visual Studio step, it may well just be sending
some config xml to the device when we change security settings. If you
want to, capture the network traffic when you 'deploy to device', and if
it just looks like some xml you can try sending it with the rapiconfig
tool.
