Error trying to access web service from pocket pc application (.NET)

by Paul Teodoresc » Thu, 31 Oct 2002 23:53:58

Hy guys ! I need help !!!
I have a strange problem with a mobile device application.
I created some web services to bring some data, I tested them on a classic
.NET windows application, it worked fine.
I put the web services in the mobile application, i compiled the
applications, it worked fine, no errors. BUT!!! I deployed the application
to emulator (same thing for device). When the application calls for the
first time a web service it raises an system.net.webexception without any
other explanation. The line with the error is on the line
Dim results() As Object = Me.Invoke("ReturnStreetsList", New Object(-1) {})
from the Reference.vb file
Can anybody tell me why this error raises and why can't I access the web
services from the mobile app?
Thank you.

1. Sync error between Pocket Access and Access on PC

I'm getting a weird ActiveSync error when trying to sync between a Pocket
Access Database and the Access Database on my PC. The device is running
PPC2002, and my PC is running Win2k with Microsoft ActiveSync 3.6 (I get the
same error with verison 3.5 also). The main error message I am receiving
is:

"On examination, table tblP2Category is either no longer on the device, no
longer in the host database, or its layout has changed. Synchronization will
no longer be performed for this table."
Now some of the tables sync correctly and then for some reason it hits a
particular table and then each table that is synced after that gives the
same error. I know the table is on my device because my vb application
pulls the data from the table with no problem. I know the table exists in
the host database (.mdb) because I have opened the table and read the data
in datasheet view. And I know the table's layout has not changed on both
the host database (.mdb) and the device database (.cdb).

Any help would be greatly appreciated. Thanks!

A portion of the log file is below:
