Hi,
I am new to SQL 2005 CE but fairly experienced with SQL 2000 and know my way around SQL 2005. I am creating a PDA app that must support the following scenario:
My company has a SQL 2000 server with a "computer assets" database. This asset database must be able to be transferred to an .sdf file (SQL 2005 mobile) on the PDA when the user docks their PDA to the desktop PC (not the same machine as the SQL 2000 server). This transfer can be via an option in the mobile app that is initiated by the user, or automatic.
The mobile application basically supports stock-taking of the assets, so users go out on site and record information about the assets. This information is stored in a separate .sdf database on the PDA.
When the user gets back to the office they dock with their desktop and then must transfer the data from the second .sdf database onto the SQL 200 server. Lets call this the "asset metadata".
thats basically it! but im having issues finding the right process to attack the data transfer tasks.
My issues:
- Firstly, how do i populate the .sdf on the PDA for development purposes? Microsoft tutorials seem to be geared at SQL server 2005 management
studio only. I only have SQL server 2005 Management Studio Express on
my development machine as well as all the necessary SQL 2005 CE SDKs and VS2005. We
do not use SQL Server 2005 at my organisation as yet and it will be some time before we migrate across. In effect im looking for something that behaves like a DTS package to transfer data across.
- How to populate the "asset database" .sdf file from the SQL 2000 server when the user has docked to their desktop PC? (This needs to be refreshed )
- How to transfer the "asset metadata" from the .sdf on the PDA to the SQL server?
ive looked at merge replication a little but am not sure whether this is what i need and again most online information seem to be tailored to SQL Server 2005.
Can anyone kindly point me in the right direction?

I have built an application for storing my flight times on my phone after each leg of a trip... I am using C# and Sql CE as the storage system for later export to a larger desktop version (in the works). My question is related to storing the sdf file on the storage card. Can it be done and what would the connection string look like since I have tried and got a error stating it can't find the sdf file in question. I have it setup right where if I were to do a fresh install it would ask for the install directory main memory or storage card. If I select storage card it installs just fine but when I run the app it does fail with the aforementioned error..
Storage Card is 2 gigs..
Thanks

I'm attempting to use RDA to synchronize a pocket pc emulator with SQL Server 2005 database by following tutorial http://msdn2.microsoft.com/en-us/library/aa454892.aspx, which uses AdvWorksMobile database that comes with SQL Server 2005.
When get to testing of "To test application features " ( step 4 of the merge replication setup lab ), I am receiving SQLCe Exception errors.
ORIGINALLY, I was able to deploy an application and view the local database on the emulator, but once I clicked "InitSinc" button, I received an error.
"Failure to connect to SQL Server with provided connection information. SQL Server does not" exist, access is denied because the SQL user is not a valid user on the SQL Server, or the password is incorrect.
Found this error listed in Server Agent Errors log http://technet.microsoft.com/en-us/library/ms172357.aspx, but it wasn't very helpful since it doesn't provide any suggestions on fixing the problems.
I am brand new to SQL CE Server , mobile programming and .NET framework in general so please bare with me
All the connections / security settings, etc that were set up were taken from a tutorial so I am not sure what SQLCeServer is complaining about. Reading up on the error on the web didn't help, it all pointed to making sure that the snapshot folder had correct permissions set up. I verified that MACHINENAMEUISR_MACHINENAME guest user had Read rights to the database so I don't think that piece is the problem. Otherwise ,Merge publication has been setup in Microsoft SQL Server Management Studio by following the tutorial.
I am trying to run this sync on my home pc so there should be no issues with any user permissions
I have IIS installed
I did NOT have SQL Server Agent running in management studio at this time
I am trying to run this tutorial on an XP machine, which is my regular home PC so I dont think there are any special networking settings to consider
I am able to hit http://localhost/AdvWorksMobile/sqlcesa30.dll from my pc OK, but when I try to hit it from a cradled emulator ( after replacing "localhost" with "MACHINE_NAME" ), Internet Explorer on the emulator gives me a "Cannot Connect With Current Settings" error message. This part wasn't part of tutorial but decided so not sure if I am supposed to be able to hit it from my emulator..so I am not sure if the fact that I can't hit it is related to the problem.
AFTER STARTING SQL SERVER AGENTin Microsoft SQL Server Management Studio, I killed the application, and after relaunching it, it hits "The Specified table does not exist [Vendor]" error. This time it doesn't even launch first - that is I dont even get to pressing "InitSinc" button. Debugger is showing that this error is hit on the following line in AdvWorksMobile.AddWorksDataSetTableAdapters
int returnValue = this.Adapter.Fill(dataTable);
I am not sure why the errors changed on me after starting SQL Server Agent.
What can I do to fix this connection problem?
Thank you so much for your help!

company is developing a database system containing information about cities, towns, and villages in the country. The number of cities, towns, and villages are in thousands and the database program should allow users to search a particular place by name. Users should also be able to search all places that match a particular value or range of values for attributes such as location or population size. This particular feature is known as a range query.
If the database is meant to support range queries that can return many cities that match the query specification, the entire operation may be allowed to take longer. To meet this requirement, it will be necessary to support operations that process range queries efficiently by processing all cities in the range as a batch, rather than as a series of operations on individual cities.Different indexing methods can be used to perform this operation. What will be your choice if:
a) database is created once and has no change over a period of time
b) database is created once and database is changed over a period of time

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?
please help me out

Dear ppl,
I am writing an application for a device (MDA Pro T-Mobile) having Windows Mobile 5.0 using
-MS .NET Compact Framework 2.0 SP-1
-SQL Mobile 2005.
-VS 2005 .NET
The application uses Merge Replication. The error occurs in the Synchronise() Method of the SqlCeReplication object.
"SQL Server Mobile encountered problems when opening the database."
repl.AddSubscription(AddOption.CreateDatabase);
repl.Synchronize();
I don't understand why I am having this error. It does create the database on AddSubscription() method but it is failing opening the database on Synchronise(). I have also tried uninstalling and then reinstalling all the SQL Mobile components in the following order.
-sqlce30.wce5.armv4i.cab
-sqlce30.repl.wce5.armv4i.cab
-sqlce30.dev.ENU.wce5.armv4i.cab
However, when i run this application on a device(Dell X50 AXIM) with Pocket PC 2003, it runs fine creating the database and sysnchronising it.
The target platform for the project is Windows Mobile 5.0 Pocket PC SDK.
Does any one have any clue what could be the problem ?
Regards
Nabeel

I am migrating a pocket PC application from VS 2003 to VS 2005 and a few weeks ago I hit the following problem when replicating
A SQL Mobile DLL could not be loaded. Reinstall SQL Mobile. [ DLL Name=sqlceca30.dll]
Scanning forums for help I saw that other people had had this problem and one
http://www.eggheadcafe.com/aspnet_answers/NETFrameworkCompactFramework/Feb2006/post25814466.asp
suggested that this problem could be circumvented by getting the replication object early and then continuously using the same object for subsequent replications.
I did this and it works a lot better now but ever so often I get another error which is
Native Error 28559 SQL Mobile encountered problems when opening the database
My only option at this point is to stop and start the application which cures the problem.

Hello,
I am developping a non-managed C++ application for PocketPC using a SQL Server mobile database.
The application is compiled for PocketPC 2003 and uses SQL Server Mobile v2. I use Visual Studio 2005. But I need to compile the application for Windows Mobile 5.0 devices. So I installed the WM5 SDK and had the WM5 into my project configuration.
The "ssceoledb.h" which I include incluses the "transact.h" file. But my problem is that this file is only provided with the PocketPC 2003 SDK and not in the WM5 SDK.
So I cannot use the WM5 configuration project with SQL Server. I also tried with the last SQL Server Mobile 2005 (ie v3.0) and the "ssceoledb30.h" also includes "transact.h".
Did I miss something to install ?
Do you know how I can resolve the problem ?
By advance, thank you for any answer.

Using MS VS 2005 (incl SQL Server Mobile)
MS Pocket PC 2005 SDK
I am working on a project that builds for Pocket PC on both Mobile 2003 and Mobile 5. The project uses/will use SQL Server Mobile to store local data.
Project created from new with support for both platforms. I include required header files ssceerr30.h and ssceoledb30.h.
Project builds fine in WM2003 configuration, release and debug.
When I build for WM5 the compiler cannot find the header file transact.h. This is included from within ssceoledb30.h. Same as under WM2003.
In WM2003 configuration if I highlight the ssceoledb30.h include in Visual Studio and open the header, it takes me to <Visual Studio dir>SmartDevicesSDKSQL ServerMobilev3.0. I then locate the include for transact.h and do the same, which takes me <Visual Studio dir>SDKPocketPC2003include. The file exists.
If I repeat the above 'browsing' under the WM5 configuration, ssceoledb30.h takes me to a different copy in the WM5 SDK directory. There is no diff between the file here and the other copy used by WM2003. If I attempt to open transact.h - file does not exist.
Fix (which I'm not too sure about, i.e. is it OK?) - If I copy transact.h to the WM5 SDK directory, the project builds.
Why has transact.h disappeared from WM5 SDK?
I can find no ref's to this problem anywhere. Is my installation of the WM5 SDK corrupt? What else could I be missing?
Is there a sample for SQL Server mobile (like the NorthwindOLEDB sample) that comes configured to build for WM5?

I receive error 25123 on my PPC (audiovox 6600) in a reproducable way (usually) with .net 2.0 application that is using SQL CE that I wrote:
Open the application
Connect to the database
Close the applicaton
Re-Open the application
Connect to the database <-- Error occurs
I will also receive the error if my application isn't the first application launched (or very close to the first to launch).
I don't believe it's a memory issue as according to the memory manager I have plenty of memory:
At boot up only start screen items loaded: 18.46 Used 49.89 Free
Launch Resco File Explorer to click EXE: 19.18 Used 49.18 Free
Launch my application (no DB connection): 23.64 Used 44.71 Free
Connect to the DB and do select count(*) from a table with 0 rows: 26.27 Used 42.08 Free
Close the application (this.Close() on the form: 19.38 Used 48.97 Free
Relaunch App and connect to DB receive error: around 38 Used around 30 free
I was unable to reproduce the issue right now while typing this message, the last sets of numbers are from memory, and include other applications that are currently running.
The only way I have to get SQL CE to load again is to soft reset the PPC. If the application is able to connect to SQL CE at least once it is fine up till I close it and re-open the application. So it either connects and runs great, or it can't connect at all.
Any help in resolving this issue would be greatly appreciated.

Hi folks, I'm new to Windows Mobile progamming, and new to this forum. Apologies in advance if I'm asking a boneheaded question, but I've done searches and can't find anything directly applicable to my problem.
I'm currently walking through the published MS tutorial in setting up an SQL Server 2005 Mobile application that subscribes to a publication on SQL Server 2005 to exchange information.
I've gotten almost all the way through... successfully set up the server components, creating the publication, etc. On the mobile side, I've been able run the cab files to install the SQL Mobile components and to create the project, add the reference to the dll, and instantiate an engine object. It compiles.
The step in the tutorial after that, though, where you specify the data source from the "data" menu, I've got a problem. When I try to use the "new connection" dialog from choosing the data connection, "MS SQL Server Mobile Edition" doesn't show up as a choice. I've tried choosing any of the other combinations, and in teh subsequent "Connection properties" section my database, SQLMobile (as in their sample) is available, but I get an error when I choose it and click OK. Clicking on "Test Connection" gives me a connection successful message.
My guess is that something about the Mobile server side components is not installed correctly on my development machine, but honestly I have no idea how to begin to fix it. Has anyone seen this problem before and know how to resolve it?
Your time and any knowledge sharing is greatly appreciated.
Thank you,
-Dana

Hi all, I'm new to mobile devices.
I have a desktop application that uses SQL Server Compact Edition. I will soon have a mobile application that will use the same database. How can I (at runtime of the desktop app, say when the user clicks a button) transfer the sdf file to the mobile device? I'm not necessarily interested in synchronizing the databases, simply overwriting the database on the mobile device with the one on the desktop would suffice.
Is something like this possible?
Thanks!

Hello,
Since my experience in VS is extremely limited, i'd like to be exused if questions sound silly.
My problem is that, at my device application project, i want to build a database that will retrieve data from .xls, or .csv, or .txt, or .mbd files. If i've noticed well, there is no support for OLEDB or ODBC, since by the time that i add tableadapter to my database.xsd and use these, after insertion i get multiple errors informing that system.data.oledb. .... or .odbc "type is not defined".
If it cannot be done, and since i still try to figure out how smart devices function, transact with databases, e.c.t. is there any suggestion?
Thank you in advance

This is strange. Cause earlier I could update the mobile sql server with no problem, but now I am getting this parsing error
it says Token line number = 1, ....
The windows mobile emulator works, but not in the actual pda.
The sql query is following
sql2 = "update flexi_pump set difference = " + divergence + " where tag = '" + tag + "'";
selecting data from the database works fine, no problem with it. only writing to it is the problem

I have searched through this forum and the news group
microsoft.public.sqlserver.ce
for this topic. I only find a post from Darren Shaffer and I requested a document.
Unfortunately, there is not a clear example of how to create a mobile database (sdf) on a desktop machine which contains VS 2005 and SQL server 2005 by using Visual Basic 2005.
I am sure a clear example in VB for this problem would help a lot of people. Hence anybody who knows how to perform this task, Please help these people.
Thanks in advance
