How to access the SQL mobile database(.sdf) using ASP.Net?
When i try to add the System.Data.SqlServerCe.dll as a Reference it shows the following error.
Error 1 Could not load file or assembly 'System.Data.SqlServerCe, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
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?
Hi, i am working with windows mobile Cf 2.0 and desktop. i got problem when i were trying to synd mobile database and ms-access database. my requirement is online i want to transfar data records from mobile to desktop vice versa. but how? i dont knwo any body would like to guide me. i am ready to accepting yours valuable views. waiting bye Rajat.
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.
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.
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 ?
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. Wayne
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
I installed the SQL Express SP2 and it supports the sql mobile database. Is there any better free tool for sql mobile database management than sql server management studio express?
Doesnt support to create/export, import scripts, doesnt support editing existing fields (name)... (i used sqlite and it has a lot of free stuffs with and without gui to manage databases...)
I am have set up a Smart Device €“ Windows Mobile 5.0 Pocket PC €“ Device application. I need to connect to & populate a listview control but:- I am having trouble connecting to my Microsoft SQL Server (sqlClient) database. Do i need to set up & use SQL Server Mobile database.
I'm porting my C++ (EVC3) application from Sql CE 2.0 to Sql Mobile 3.0 (with OLE DB). To compact a 2.0 database, i used ISSCECompact interface. But it doesn't exists with the new version. I've only found C# and VB.Net samples in MSDN ...
We have been asked to look into using stored procedures with SQL Server 7.0 as a way to speed up a clients site. 99% of all the articles I have read along with all the books all say Stored Procedure should be used whenever possible as opposed to putting the SQL in your ASP script. However one of my colleagues has been speaking to Microsoft and they said that that they were surprised that our client wanted to use Stored Procedures as this was the old method of database access and that now he should really consider using COM objects for data access as itis much faster. Has anyone got any views on this or know of any good aticles regarding this matter ?
Hi there, I need to create a synchoronization with the Server Mobile (displayed in the Pocket PC emulator) once the website (SQL server Database) is updated. Is there any coding available? How is it possible? PLSSSSS HELP ME....
I am developing a Translator for a mobile phone and I am using MS SQL server 2005 for creating my database.. I am having a problem in creating a relationship between my tables.. I have the following tables: English(engcode,engword) - engcode is primary key Esperanto (espcode, espword) - espcode is promary key EngEsp (engcode,espcode)..
The problem is that the icon "relationship" is disable in sql 2005 and i am nt able 2 create the relationship..
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.
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?
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.
I am trying to build a simple mobile application. I am very new to this. Thus I am trying to access the build in database in the folder C:Program FilesMicrosoft SQL Server 2005 Mobile EditionDeviceMobilev3.0Northwind.sdf. I am following the steps in the wizard to help me. When I press test connection is say Test Connection Succeeded. But when I press the ok button I get this error as "Unable to find the requested .Net Framework Data Provider. It may not be installed". I am running VS 2005. Can anyone pls help ?
Is it possible to have a Windows applications (based on .NET Framework 2.0) connect to a SQL Server Mobile database?
I manually added the the System.Data.SqlServerCe.dll (retrieved from C:Program FilesMicrosoft Visual Studio 8SmartDevicesSDK\SQL ServerMobilev3.0System.Data.SqlServerCe.dll) to my Windows Form project. When I start the app, it gives me an error message:
{"Could not load file or assembly 'System.Data.SqlServerCe, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.

I developed a mobile application PDA using the Compact Framework 2.0. And using typed datasets
I have also developed a web service. When the PDA is connected to the Internet it can access the web service and get all the data that is in the sql database. The user can add new records, update existing records, and delete them. So the web service acts like a middle man.
In the PDA the data is filled using typed datasets.
However, the customer now wants to be able to interact with there data on the PDA, currently they have to be connected to the Internet. But if there is no internet connection, then they will still like to add, update, and delete the records. Then once they have a connection, all these would be updates with the sql database.
I am working on an application that was initially set to connect to a SQL database.
The application is for a Pocket PC and now I have converted the original SQL database to a SQL Mobile database.
Does anyone know if there is a way to change the the code to be able to access the SQL mobile database without having to go through all the code and manually make the changes?
This is a great tutorial and it's a shame one of the more important steps was missed. In the €œCreate the snapshot user€? section you you find the steps to create the snapshot_agent account. Then in the €œCreate the snapshot folder€? section you find the share and folder permissions. However, at no point do the instructions advise you about adding the snapshot_agent to the SQL Server Logins. The result is that agent cannot perform the initial snapshot but you won't find this out until 50 steps later after Step 10 in the section €œCreate a new subscription".
To get back on track, openthe Object Explorer's Security section and add the snapshot_agent to your logins. Then using the "User Mappings", set an appropriate level for the SQLMobile database role. Once completed you then need to run the agent.
Right-click the SQLMobile publication you created and select "View Snapshot Agent status". From that dialog you can select "Start" to run the agent. When it completes, you can return to the tutorial section "Create a new subscription" and continue with the tutorial.
I am studying the tutorial in SQL Server 2005 Mobile Edition Books Online, and the topic is Creating a Mobile Application with SQL Server Mobile. I have got a problem when creating a new subscription after created a new SQL Server Mobile database. And the problem is shown below:
New Subscription Wizard
- Beginning Synchronization (Success)
- Synchronizing Data (100%) (Error) Messages * Failure to connect to SQL Server with provided connection information. SQL Server does not exist, access is denied because the IIS user is not a valid user on the SQL Server, or the password is incorrect. HRESULT 0x80004005 (29061)
* 無法完æˆ?作æ¥ã€‚
- Finalizing Synchronization (Stopped)
- Saving Subscription Properties (Stopped)
Before I have met this problem, I have finished all the task. And I can browse the localhost web site by using anonymous account even I use internet explorer or browse the directly in IIS.
I want to physically move my .SDF file to my desktop and then access this file from VS 2005 VB.NET. Ideally, I would want to access this .SDF file from MS Access 2003 but I undersand this is not possible.
Here are my VS 2005 VB.NET statements....
Dim ConnPPC As New System.Data.SqlClient.SqlConnection("Data Source = C:Documents and SettingsG014436My DocumentsSQL
MobileActMgr6CE.sdf")
Dim mySqlDataAdapter2 As New SqlDataAdapter("select * from T0002_AE_Activity_Entry", ConnPPC)
mySqlDataAdapter2.Fill(myDataSet2)
On executing the last statement(fill)...I get the following error.
function failed: 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
We are building a small utility tool application for clients who sometimes may not access the company central database. The application use the merge replication to implement the Web Synchronization of the SQL server database and SQL server compact edition database at the client machine.
After the installation of the application, we use the following code to create a sql server compact edition .sdf file.
SqlCeReplication repl = new SqlCeReplication();
repl.AddSubscription(AddOption.CreateDatabase );
repl.Synchronize();
Some machines run the process successfully, and the database .sdf was created and replicated successfully. However, some machines failed, the error message got is "SQL mobile encountered problems when creating database". All the client machines are Windows XP. We did some research and found someone commented SQL Server compact edition file (.sdf) is a medium integrity level resources file, in some windows system, IE runs in protected mode and is a €œlow integrity€? process, which caused the Access Denied.
Can anyone here know any solution to this issue? Any help is highly appreciated.
So I started an SQL CE database for use inside a mobile application. I used SSMS to create a .sdf file (because if I let Visual Studio do it, SSMS can't open it because it will be version 3.5).
The reason I wanted to use SSMS is because I wanted to be able to design the database in design view, and populate it with initial information for the application to use. That means adding tables and rows.
The problem is, SSMS doesn't seem to have a design view available when working with CE databases. It also doesn't seem to have a feature for adding rows into tables. It's essentially as useless as VS2008 for designing my mobile database. It only lets me add tables, and I can't even do that visually in design view. I have to use those cumbersome forms.
Is there any way to design a CE database in design view? And add rows of data into tables? It feels like I'm overlooking something.
Note: I dont need to subscribe or publish the database. The mobile application just needs to use the database as a repository.
