I made application (using .NET) to transfer data using PDA via GPRS and
then upload data to database server. The data not update old data but make
new insert new data to database server.
If we use USB to synchronize data from PDA to database server, we can use merge
replication. But i still confused how to synchronize data, if we transfer data from
PDA via GPRS, then insert to database server???

I have the following problems:
- in Active Sync 4.5 there is no DMA connection available
- when selecting a DataSource in VS2005 I do not have SQL SERVER Compact Edition in the list
While testing this problem out, I found it has something to do with this update SSCE31VSTOOLS-ENU and SSCE31VSTOOLS-DEU. Both updates do not run. Instead I get a message that necessary files are missing or do not have the right version for updating.
How could I solve this problem? What is the right order to install this beasty patch?
Best greetings from Germany.

Hello!
I don't know if this question belong to sql forum or smart device forum.
So far i was able to sync data between pda and the sql server pc, over a wi-fi LAN using Remote Data Access.
Now i want to do the same but without using the wifi LAN, i mean, i want to be able to over a gprs connection, do the same data synchronization.
My main question is how to get access to the sql server database ? My connection string (obviously) only works in LAN.
My doubt is how can i access my sql server database data ?
I need some help over here, i really don't know how can i overcome my current problem.
Thank you

I want to synchronize my database on Pocket PC / The Emulator that use WM5 and SQLCE3, but the synchronize is doesn't use IIS as the bridge, but i want to use ActiveSync as the synchronizer bridge. The rule like this.
1. Have database on Pocket PC.
2. Have application on Desktop PC.
3. When device or emulater placed on cradle, then the database automaticaly synchronized with database server on desktop pc.
Why I want to use ActiveSync as synchronizer.
1. I have the Pocket PC cradle. So my device can synchronized using ActiveSync.
2. I have internet connection on Desktop PC. So why i must pay more for GPRS if i only need to synchronize my device with my desktop pc.
Thanks.

Hello. Is there any possibility to connect and proceed merge replication between SQL Mobile and SQL Server 2000 SP4 using ActiveSync? I need to deal with this situation:
- mobile application is working using self .sdf database but from time to time it connects to SQL Server and do some synchronization (synch or asynch, really doesn't matter). But, when there is no network connection (broken, suspended, wifi broken etc.) I have to create an option - Pocket PC will land into cradle and I have to synch all changes made in SDF and SQL Server using ActiveSync (or something like that - via USB).
So my question is : is there any simple mechanism to do this? Or I have to write some Active Sync manager which will be dealing with my replication? (pretty hard to do). Awaiting answer - Maciej Wysocki.
PS. I am using Windows CE 3.0 but I can setup Windows Mobile 5.0 too, I am just wondering if there is any chance to make this type of synch. working.

I have a WM6 phone which got an Exchange server setting for my email. When I connected the device by USB, the activesync will show "Synchronization could not completed. Try again later. Support Code 80072f7d". When I search the result from this forum. The answer is not related to mobile phone issues.
Will anyone able to help?
Thanks, ppdog

Hi!
I have some questions about the MSDN article "Step by Step: Developing a SQL Mobile Application with Visual Studio 2005 and SQL Server 2005" (it is msdn2.microsoft.com/en-us/library/Aa454892.aspx).
Everything works good up to Exercise 3: Synchronizing Data Between Any Backend Database and SQL Mobile Database Using a Web Service. It is said that we need a DataService.asmx file to be enetered into "Web reference name". Unfortunately I can't find the HOL302_SQL_Mobile to download and install this file. Where I can find this file?
Can anyone tell me how can I do such a replication(C#)?
How can I synchronise data from mobile device to SQL Server using GPRS connection? (I only know replicating over USB).

I have tried using the SqlClient class to connect to the database, but I haven't had much success. Here is my setup:
Desktop/Workstation has Windows XP, ActiveSync, .NET Framework 2.0, and SQL Server 2005.
The production Workstation will have 2000; so I do want to ensure SQL Server 2000 compatibility with my solution.
Handheld device is an Intermec 751g with docking station, hooked to PC host using USB connector cable and ActiveSync, Windows CE 4.2, .NET Compact Framework 2.0 with SP1 and latest patch.
Development tools consist of Visual Studio 2005 and C# .NET language.
Note that when I attempt to ping my desktop from the handheld command prompt I get "transmit failed, error code 11010".
Also, I am able to access the Internet from my handheld device.
My error is encountered when I execute this fill code:
int returnValue = this.Adapter.Fill(dataTable);
Please note that all of my code is generated by the VS 2005 IDE at this juncture, as I am simply trying to get the plumbing to work.
Here is the error that I encounter:
System.Data.SqlClient.SqlException was unhandled
Message="SqlException"
Class=20
LineNumber=0
Number=6
Procedure="ConnectionOpen (Connect())."
Server="09Q-GHAZEL2\SQL2K5"
