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 ?
