Synchronizing Data Between Any Backend Database And SQL Mobile Over GPRS
Apr 9, 2007
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).
ISSUE: While synchronizing data between the PDA and MS SQL Server database, using Active Sync connection, the sync process fails at times and displays an empty error message box and occasionally it shows the following exception: Error During Synchronization: A native exception occurred. ExceptionCode:0xc0000005 ExceptionAddress:0x01627b28 Reading: 0x1e000000 OK to terminate CANCEL to debug Moreover the .SDF file on the PDA gets corrupted. The ActiveSync connection drops as soon as the sync process fails. Later when the .SDF file is deleted and restored the synchronization is successful. Note: The replication monitor in the SQL Server indicates that the synchronization was successful even when the above error occurs.
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???

Hi I have two servers, on one i have SQL Server 2000 ( root ) and on the second SQL Server 2005. I need synchronize some data ( not the whole database ) on 2005 but i can't use Analysis Services . What i can do in this situation ?
After creating mobile database into sql server 2005 management studio, how to insert the records from sql server 2005 management studio into and mobile database from excel file?
I'm writing a site in ASP.NET 2.0. I have business logic that contains two methods:ModifyUserInDB() // Modifies user data in a SQL 2005 tableandGetUserFromDB() // Gets user data from the SQL 2005 user tableIf the two methods above get executed at the same time by two different users (but on the same record in SQL 2005), how do I prevent the data from being corrupted? Does SQL do this automatically?If I make the methods static, and synchronize them, will it fix the issue? Are static objects the same instance for all users?
I have several situations where I have values stored in multiple tables (yes, I know that isn't a good practice but it is my reality) and I need to make sure that they stay consistent.
The problem is, they can be (and frequently are) updated from both locations.
I was going to use an update trigger on each to update the other but I can see that causing potential deadlocks.
Surely I am not the first person with this problem but I haven€™t been able to find anything in the help files or on the forum.

hi..need help here, I sometime get error when syncronizing data at New Subscription Wizard, and sometime I dont.but right now i cant sync, this is me error messages : "Synchronizing Data (Error) Messages A request to send data to the computer running IIS has failed. For more information, see HRESULT. HRESULT 0x80070002 (28037)
The operation could not be completed."
I've turn off the firewall, turn off the antivirus, plug the LAN cable but still error (Maybe it has to do with it).A long time a go I've had this error, and then I decided to reinstall SQL Server and try it again and it work, now it back to me again, do I have to reinstalled it again(hopefully it solved my problem)?or any otherway?
And want to ask about SQL Mobile, When I choose the Merge, the uniqueidentifier will be add at my table right?what should I do at inserting query process, I cant just insert it with NULL value right? After my subscription doing input data, is it my publications will be automatic updated? I'm little lost here..need advise
I tried to subscribe to the database that is published on my laptop running on windows XP professional SP2 and using SQL Server 2005. However, in the second step (synchronizing data) the following error message occured:

A request to send data to the computer running IIS has failed. For more information, see HRESULT. HRESULT 0x80072EE2 (28037)
I will have to setup two windows 2000 servers at separate locations. Each server will host the MS SQL 2000 database. The data on both database will need to be in sync in real time. Is it possible to do? If yes, any suggestions of how do do it?
Can someone recommend a utility (preferably open-source) tosynchronize changes across servers? I need to bring only data over insome cases, and only objects in other cases. Any ideas?Thx!
Hi, I have developed a software which is to run on multiple PCs on a network sharing the same database on an inhouse server. There is another database which has some similar tables that sites on a server where the website is. I need to have the common tables synchronized. How is this possible and what issues will I have in doing this? Well there be a problem if the synchronization happens when someone is using our software which is making some changes to that table at the same time? Or if someone on the website is entering some information that updates the database?
I am using Visual Studio 2005 with C#. Access Database.
We have a database in an AlwaysOn Availability Group that has gone into a state of Not Synchronizing / Suspect on the secondary.
The reason why this happened is because the secondary ran out of disk space so the log file wasn't able to be written to. The database was set to synchronous mode.
Is the only way to recover from this to do a re-initialization or is there another way to recover?
Hi,I'm new to SQL and databases in gnereal but am trying to source anapplication for windows that will sit on top of a small SQL database Ihave (created for local scout troup), I want an easy way to retrieve/add/view data from backend in nice menu-driven GUI format (no cmd-line).Can anyone recommend a useful app I could source to do thistask....thanks in advanceterry
We are new Access users and trying to take our database live...here are some of the problems we're facing.
When we split our Access database into a Backend and Frontends, a couple of strange things happened in the Frontend: 1.) When we run our queries, multiple copies of the same record are displayed (this is wrong). 2.) When we look at those queries in design view, the field names are preceded by Expr1, Expr2, Expr3, etc.
We have a large number of queries. How can we fix this problem?
Also, if anyone knows any websites or resources that can help us understand what things like Expr1 mean (a reference) that would be helpful too!
We are not a very advanced group of access users and are trying to split our database for a research study...here is our question:

Also if anyone has a good source for trouble shooting this or simmilar difficulties we'd appriciate any spots or advice.
I am trying to set up replication between a central office and multiple sites. This will be merge repl, since either central or satellites can be modified. However, one issue I ran into is setting up subscribers. I don't always have the option of starting with a publisher's snapshot; some of the subscribers have their own data already, which may or may not overlap with central site, and which needs to be synchronized into the central site somehow.
So far, I haven't seen any solution for this kind of scenario, at least nothing out of the box. Am I doomed to having to roll out custom data transfers (I don't think I can use DTS since all sites are running Express), or is there some standard way of doing this?
Is it possible to use SSIS to synchronize the data between a Foxpro .dbf and a compatible SQL Server table on a near realtime basis?
I have succesfully created an SSIS package that will insert data into the SQL Server Table but this is only useful for migrating data. What I need is a way to insure that the data in the SQL Server table matches that in the .dbf on a near realtime basis.
Or is there a way to link from SQL Server to the .dbf (similar to an Oracle DBLink).
how do i connect my PDA application to the central server? should i use GPRS connection? if yes then how can i use it? whats the code for connection thgrough GPRS? and what are the other options available? i m also using merge replication for synchronization.so can i use GPRS with that?
hi, i am developing one location based mobile application in c#(.net compact framework).i m using ActiveSync to connect to device emulator.i m getting confused that would i be needing to connect device using ActiveSync everytime even after deploying it onto actual device?or i need to use GPRS connection? or i need to connect using both? and whats the code fro checking GPRS connection status? i m using merge replication fr synchronization. please guide me as soon as possible..
can anyone please guide me how i can check whether the GPRS connection is active or not on windows mobile based application? whats the code for it? because i need to synchronize my data based on the status of GPRS connection. thanks and regards dhruvi
Dear All, i have a question abt winCE 4.2 and SQL server CE. i am using VB.net of Visual Studio 2005 My platform is using a PDA with winCE 4.2 and SQL server CE. The Host program is using dbf files on desktop side.
I got a problem of how to sync / read the sql CE data from a windows application.
so, i wanna ask,
1. any method to access the data from winCE data by windows application? or can i convert the sdf file to windows readable files? or any others?
2. Can i use a MDB to sync with SQL server CE? can i synchronize the mobile device which has a SQL Server CE database with the Access database on the desktop?
last question, 3. is that windows CE .net 4.2 not support pocket access (cdb) anymore?
