Registration Of Mobile Data Provider For SQLCE
Jun 26, 2007
Hi All,
I have just installed SQL Server Compact Edition (including the SDK) for use with Borland Developer Studio 2006. I have an ADOConnection component on my form, but the Provider I want (Microsoft.SQLSERVER.MOBILE.OLEDB.3.0) is not available. Typing in the connection string: "Provider=Microsoft.SQLSERVER.MOBILE.OLEDB.3.0;Data Source=C:Program FilesMicrosoft SQL Server Compact Editionv3.1SDKSamplesNorthwind.sdf..." results in an "Unspecified Error". I have checked the HKEY_CLASSES_ROOTCLSID and the provider associated with SQLCE is not there.
I've read a couple of posts indicating that it should have been registered during install. Is this the case or do I have to do something more to register this provider?
I've checked the assembly (system.data.sqlserverCe - it seems OK) and re-registered sqlceolebd30.dll. I'm not sure what else needs to be done.
TIA,
Luke

Hi,
I need to do a Select and after a Insert during a Transaction. But when i want to commit this transaction i've the following error message :
The transaction can not be committed if there are any opened cursors in the scope of this transaction. Make sure all data readers / result sets are explicitly closed before committing the change.
I don't understand this error message. How can i close my cursors.
Before my Insert i'm closing my SqlCeDataReader and i dispose it. My SqlCeCommand are also closed and dispose.
Do you have any ID?
Thanks.

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 have an SDF using SQLCE 2.0. When I run the app on a Pocket PC device running Windows Mobile 5.0 I get 0x80004005 and 0x80040e21 errors. The same app executes fine on PPC 2003.
The app is written in VC++ using and uses the SQLCE OLEDB Provider to access the SDF. It is complied with eVC 4.0
Any idea as to the problem?

The interface ID IID_ISSCECompact has been removed from ssceoledb30.h thus causing a compile error on this statement:
hr = m_pIUnknownProv->QueryInterface(IID_ISSCECompact, (void **) &pISSCECompact));
So how does one compact a database using the 3.0 OLEDB Provider and VC++?
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!

Hi,
After reading this helpful blog entry:
http://blogs.msdn.com/sql_protocols/archive/2007/05/13/sql-network-interfaces-error-26-error-locating-server-instance-specified.aspx
I think this might be a good place to ask the following question.
I am writing the error handling code for my data access layer for a web application. I am using the Enterprise Library Data Access Application Block. Although this supports generic database connections, I realized that I need to handle errors specific to each database type. Microsoft SQL is the only database type I am using for now, so I am using a try...catch (SqlException e).
In testing my code, I intentionally changed the instance name in web.config to a name that does not exist. I get the very popular error 26 - Error Locating Server/Instance Specified. This is returned as a SqlException, but the SqlError.Number property is set to -1.
Am I getting "-1" because the provider hasn't actually connected to SQL yet, so it doesn't have an actual SQL error number?
Can I assume that (SqlError.Number == -1) is always a fatal, provider-level connection exception?
Will the provider ever use another SqlError.Number of its own? Or do all numbers besides -1 come from the SQL sysmessages table?.
Is there a comprehensive list of what exceptions might be raised by the SqlClient provider, including #26?
The reason for all the questions is that in a web application, I want to prevent the end-user from seeing the "real" exception if it has to do with configuration errors. However, maybe there are other errors that the user should see and handle? It's hard to know without a full list of SqlClient provider errors, along with the SqlError.Number that each error maps to.
Thanks and regards,
Mark

I am currently upgrading our ppc app (written in .net 2003) to .net 2005 and from sqlce 2.0 to 3.0. The new application runs out memory(storage) when handling lots of data transactions (both in case of using sqlcedatareader, and dataset ). There is no memory leak issue here, sqlce 3.0 simply uses a lot more (3 times more) memory than sqlce 2.0.
Our applicaton runs fine using sqlce 2.0 and .net 2003, but fail due to memory shortage
with the upgrades(which has the same code). Anyone can shed some lights on this issue?

I have created a registration form. It works fine IF ALL fields are filled. However, all fields are not required. When I test the registration page and leave a field blank, I receive the following message:
Exception Details: System.Data.SqlClient.SqlException: String or binary data would be truncated. The statement has been terminated.
Stack Trace:
[SqlException: String or binary data would be truncated.
The statement has been terminated.]
Even if I leave a validated field blank, I receive the same message instead of the required field validation control error message.
Here is the code for the registration page. I use web matrix to create the code as directed in the tutorial.
Can anyone help a newbie?

I have an application where I'm trying to store xml data in a db field defined as ntext. I have a dataset and table adapter setup in VSNet 2005 and SqlCe 3.1. When I look at the table adapter in the VS designer it shows the field with a type of String and a size of 2147483647 which appears to be correct. Also, if I look at the code generated by the MSDataSetGenerator tool it shows the parameter defined in the same way as in the following
param = new System.Data.SqlServerCe.SqlCeParameter();
param.ParameterName = "@Questions";
param.Size = 2147483647;
param.IsNullable = true;
param.SourceColumn = "Questions";
this._commandCollection[2].Parameters.Add(param);
My problem is that when I run the application and try to insert an item into this column the application throws an exception related to corrupted memory. Trying to debug the problem I found at run time, the param.Size value for the ntext parameter had been set to 255. Since the specific xml I was trying to insert was 410 characters in length I'm guessing that this is what is causing the crash.
Is the expected behavior (the setting of the size to 255 that is)?
If not, am I missing some trick here?
Thanks
Neil

Hi
We are building a near real time application in Windows Forms, that stores data in SQL Compact Edition.
The client receives messages via UDP socket and performs insert / update operations to the db accordingly, and the requirement is to update a data grid with the changes.
We tried querying the db and receive a ResultsSet which is sensitive and scrollable, and bind a ResultSetView to the Grid. But, since the updates are made from another thread, the grid is not being refreshed.
What is the best approach for achieving this?
Thanks in advance,

Does anyone have any instructions on how to go about uprading a .sdf file
from sqlce 2.0 to sqlce 3.0?
I found this on an msdn website
(link: http://www.microsoft.com/sql/editions/sqlmobile/upgrading.mspx) but
as you can see its very lacking on detail. (I included the link and content
referring to upgrading the database files so you won't have to go to the link
to see the part referring to upgrading the database.) I tried to run the upgrade.exe on my device but it doesn't explain how you're supposed to point it to the .sdf that you are trying to update. Here is the content on the above web page.
Upgrading Database Files
You can upgrade a database created with an earlier version of SQL Server CE
2.0 to a database created with SQL Server Mobile by using the SQL Server
Mobile Database Upgrade tool (upgrade.exe). The Database Upgrade tool runs on
a smart device.
When you run the SQL Server Mobile Database Upgrade tool, the new SQL Server
Mobile database is created on the smart device. The new database, with the
file name extension .sdf, contains all the data that was in the source
database. You need to reinitialize the upgraded database to continue using it
for replication.
Note: If you are using replication or remote data access (RDA) as a
connectivity solution before upgrading to SQL Server Mobile, you must
synchronize the source SQL Server CE database (subscription database) with
the SQL Server database (Publisher). The reason for synchronizing before
upgrading to SQL Server Mobile is to ensure that any changes that exist in
the tables on the SQL Server CE database are updated on the SQL Server
database, because after the upgrade you must resubscribe or repull using the
new database.

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

Recently I installed the .NET data provider for Teradata.
In a regular C# application I can add the namespace, "using
Teradata.Client.Provider;" to connect to this data provider
directly without going though ODBC or OLD DB so I know it works.
However, when I open Reporting Services (new project -> Business Intelligence
Projects) I do not see how to add the Teradata .NET provider. I only
see the same standard data types as before. I have searched and I do
not see how to add the Teradata .NET provider to the available "Type"
list when you click €œAdd New Data Source€? to your report.
Thanks!

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

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

We just changed the dev environment to sqlagent. From then we were unable to see the reports on the report server because:
An error has occurred during report processing.
Cannot create a connection to data source 'IHRSDataSource'.
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
this error is cropping up.
To Resolve this issue, we checked the Surface Area Configuration and also checked the Reporting Service Configuration . There seem to be no problem and everything looks ok.
Please help me in resolving this issue.
