Connection From Windows Application To Mobile Device(*.sdf)
Jan 21, 2008
Hi,
I'm writing a windows application using VB.NET 2005 that must connect to Pocket PC via ActiveSync to read data from SQL Server CE. This is my code:
Dim cnn As New SqlCeConnection
cnn.ConnectionString = "Data Source =Mobile DeviceStorage CardProgram FilesMyAppMobileDB1.sdf"
cnn.Open()
But I get the following error:
The path is not valid. Check the directory for the database. [ Path = Mobile DeviceStorage CardProgram FilesMyAppMobileDB1.sdf ]
Any help would be greatly appreciated!

Long story short -
Have two C# applications - one WinForms desktop app, the other a WinForms smart device app. Both use SQL Server Compact CE 3.5 to store data locally. Both work just fine.
Now the desktop app needs to open and update the .SDF file that is stored on the Windows Mobile device. (Device will be docked via USB.)
What format would the path to the .SDF look like that the WinForms application would need to specify in order to open it?
Thanks for reading.

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.

Dear ppl,
I have a windows mobile 5.0 application that syncronises with SQL Sever 2005 (Merge Replication). The replication works fine without SSL. But when using SSL it doesn't work .On the device i get an error
28037, A request to send data to the computer running IIS has failed.
I have created a a Wild Card Certificate (*.domain-name.net) using Microsoft Certificate Services (Stand Alone) and setup the replication website with replication virtual directory under it , in IIS, to use this certificate. The host header for the replication site is set to "sql.domain-name.net". I have binded the host headers to the port as well.
I can access the https://sql.domain-name.net/replication/sqlcesa30.dll from remote computer and device and it says Microsoft SQL Server Compact Edition Server Agent, that means it is setup correctly.
I have installed the certificate authority and its wild card certificate on the device Root Certificates. Now when I call repl.syncrhonise() from device .. it throws exception with error 28037, A request to send data to the computer running IIS has failed.
which i think means, it can't find the service url.
I am not sure what is the problem..something to do with Trust - SSL certificates... Is there any thing i am missing ?
Awaiting,

We have setup a 32-bit IIS server on a 32-bit machine. Installed necessary SQL Server components (32-bit replication components). We have installed SQL Server 2005 64-bit SP1 with latest hotfixes on a 64-bit machine.
On the Mobile device we installed SQL Server 2005 Mobile.
When we start mergereplication the problem we have is error 28009 (An instance of the SQL Server Reconciler cannot be created) on the mobile device. I read allot about it, but still have a questetion.
Should this work?
I found the doc: SQL Server 2005 Upgrade Technical Resource Guide:
Note: If your upgrade involves SQL Server CE subscribers, you must perform additional actions on the IIS server. You will need to install SQL Server 2005 client connectivity components along with SQL Server Mobile Edition components on the IIS server. You will also have to replace sqlcesa30.dlll, sqlcerp30.dll, and all the replication components on the IIS server.
From this I conclude it should work or is the doc in error?
If it does not, what can we do?
32-bit SQL Server 2005 on the 64-bit machine should work. (Can a 64-bit SQL Server 2005 run alongside 32-bit SQL Server 2005?).
Beste regards,
Hans Mank

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?

Hi
My application :
On PC : Access application + Access DB
On PocketPC : Embedded Visual Basic 3.0 application + PocketAccess DB
I synchronise my DBs through ActivSync.
It runs good before Windows Mobile 5.
My customers asked me for new PocketPC with this application, so I bought some new PocketPCs : but as I see, syncronisation with Access is no more supported.
So what are my solutions ?
My customer wait for there PocketPC, so I need a quick solution, I don't want to rewrite all my application now.
My application run before WM5, so now I don't want to have to pay for a Visual Studio .Net, some SQL Server, etc ....
Please, what are the solutions that won't cost me more than the time that have already lost with this new Windows Mobile 5 ?

Hi there, i am building a mobile app using vs 2008, the app has about 8 - 12 forms that collect data.. i am thinking of
i am trying to decide how i want to save the temporary work data while the user fills the data collection forms.
when the user selects to create a new report, i will
create a new xml file...
as user moves from form to form, i will update the file
when the user has finished filling up all the data i will create a transaction and insert the data into the sql ce database and delete the file...
i will be using sql ce 3.5
i think it supports transactions
i think it also supports identity.... i am using sql management studio 2005 standalone , so i cannot visually modify the 3.5 sdf.,..,. is there a tool for 2008 that will let me visually modify the table(s)? i dont want to use the 2008 feb community edition...
is there a better way to do this? should i skip the xml and go directly into sql ce insert (for the first record creation) and updates? i think this will be a performance killer on a win mob devilce (5.0)
p.s. i cannot store data in a class, and then commit the class to the transaction because if the application crashes i will loose class data, so xml file will be needed.,
suggestions?

I've read that microsoft.applicationblocks.data for .net v2 can't be deployed to a mobile app, and my experience bears that out. So I 'm wondering if there are application blocks for windows mobile 5 that would know how to both talk to sql server mobile and sql server 2005. I see OpenNetCF has a port but as far as I can tell, they only address sql server mobile and not talking to a sql server 2005 remote database. I can use the OpenNetCF version for my sql server mobile requirements, but I'm hoping there is an encapsulation of sqlclient calls for communication with my server db.
thanks

Basically I've been using Visual Studio 2005 for a few weeks now moving a Pocket PC project from 2003 to 2005. When I hit the Start Debugging Button every time until today the project would rebuild and deploy to my pocket PC allowing me to debug etc but now I get
The remote connection to the device has been lost.
Please verify the device conection and restart debugging.
I used to get this problem in VS2003 sometimes and just like the numerous posts on different sites that I've looked at the problem eventually goes away and I'm none the wiser. One guy said that he found that if he went to bed the problem was resolved when he came back!
My PDA running Windows 2003 2nd Edition is directly connected to my PC via a USB port. I've rebooted my PC and done a soft reset on the PDA but it didn't help. I'm using ActiveSync 4.1.
Does anyone know how to resolve this problem?

OK
We have always used sql servwer login to the servers for all our applications for out intranet apps
And we use windows auth to do development
So when we do that we logon to wuindows, and then just connect, with no password required
But how does an application "logon" to connect to a database
Is it just in the connection string just like sql server auth
or is it different?

Hi all,
I think I can do this, just want to check
Can I have an sql server database (mdf file) on a server and allow windows applications at different site manipulate the database.
As far as I am concerned the only thing that needs to be configued is the connection string..is this correct.
[i would rather use windows applications rather than asp pages]
If I can, the best way to manipulate the database is to use stored procedures. How would I do the following to create and execute the following proposed procedure:
Insert data into a table
Update another table as a result
Execute the store procedure on a form to execute these two statements
Thanks in advance

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

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?

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.

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!

I have been unable to properly install SQL Mobile 2005 on my armv4i windows CE 5 device. Below is a summary of what I have found and done. Any help in resolving my issue will be appreaciated. Thanks in advance for your help.
Symptoms:
No errors occur during installation of SQL Mobile on the device via cab files (either deployed through VS2005 or manually copied and installed on the device)
SQL Mobile 2005 appears to be installed, can see it in the device remove programs list. All 7 SQL Mobile dll files are present in the windows folder. (sqlceca30.dll, sqlcecompact30.dll, sqlceer30en.dll, sqlceme30.dll, sqlceoledb30.dll, sqlceqp30.dll, sqlcese30.dll - version for all files is 3.0.5206).
The following error occurs when attempting to create a new or open an existing database using SQL Mobile query analyzer on the device - "Failed to initialize the provider. Please make sure that SQL Server Mobile Edition is properly installed".
Problem is not isolated to SQL Mobile query analyzer, a similar problem occurs when attempting to instantiate SQL objects from within a C#.Net smart device test program - "Can't find PInvoke DLL 'sqlceme30.dll'.
Problem is not solved by copying SQL Mobile dll files to program folders.
No registry entries exist for any of the 7 SQL Mobile dll files under the HKEY_CLASSES_ROOT.
None of the dll files for SQL Mobile can be registered manually via the regsrvce.exe program. The error code c1 is returned - invalid win32 application (Note SQL CE 2.0 dll files can be successfully registered via this program).
Background:
The desktop used for development is running Windows 2000 sp4. The develpment enviroment is Visual Studio 2005 Professional Edition (version 8.0.50727.42 (RTM.050727-4200). The version of the Microsoft .NET Framework installed is 2.0.50727. The programming language is C#.NET. The device is a 64 MEG Armv4i device running a custom image of windows CE5. The CE5 image was created by Platform Builder with all QFE's through 2005 applied. .NET Compact Framework version 1.0.4292 and SQL CE version 2.0 are included as part of the image (both are in ROM). .NET Compact Framework version 2.0.5238 and SQL CE Mobile are installed via CAB files in the order defined below:
netcfv2.wce5.armv4i.cab
sqlce30.wce5.armv4i.cab
sqlce30.rep.wce5.armv4i.cab
sqlce30.dev.ENU.wce5.armv4i.cab

Hello,
I am using the SQL Reporting services with SQL Server 2005. I am able to view my reports in the report manager however, when the report generates on my device it shows blank of 0 pages. I created a simple test report with just a header, company's logo and contact info and still no luck. I am using anoynomous user access and have given IUSR datareader access in SQL Server. Not sure where I am going wrong. I feel like I am so close...If someone out there had any success viewing reports on mobile device (WM5.0) and would be so kind to share their experience or knowledge, I would greatly appreciate it!
Thanks.

The literature has so many options I don't know where to start.

Hello,
VS 2005 & SQL server 2005
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.
What is the most efficient method to do this.
Many thanks for any suggestions,
Steve

I just upgraded our application from SSCE 2.0 to SQL Mobile. Our app is written in C++, and we use OLE DB for most of our queries, including the routine the downloads and inserts our lookup table data. This application is running on a Dell Axim X51.
Using SSCE 2.0, this routine takes 236 seconds, with most time spent inserting data into various tables (using OLE DB). The resultant database size is 15.1 MB.
Using SQL Mobile, this routine now takes 675 seconds, with a resultant database size of 27.9 MB!! There is a noticable increase in time when the downloaded data is being inserted into the database.
What would be the reason(s) for the slower performance and the increased size of the database? This appears to be a monumental step backwards in performance. Any suggestions regarding improving the perfomance and size?

I've written a query to pull data from a SQL Mobile database which seems to completely hang the device when I run it (I waited several minutes before warm-starting). Yes, it's a bit complex, but it works fine on the desktop version--completes pretty much instantly.
Are there any limits to SQL Mobile that might prevent me from writing such a query? There are not very many records in any of the tables (all are <20, except one which is ~2500).
Here is the query:
------------------------------------code---------------------------
SELECT oi.ProductID, g.GenusName, Species.SpeciesName, f.FormName, f.Abbr, sz.Sizes, su.SizeUnits, su.Abbr, pa.PackageName, pa.Abbr, oi.NumRequested, oi.NumProvided
FROM OrderItems oi
JOIN Products p ON p.ProductID=oi.ProductID
JOIN Varieties v ON p.VarietyID = v.VarietyID
JOIN Genus g ON v.GenusID=g.GenusID
JOIN Species ON v.SpeciesID=Species.SpeciesID
JOIN Grades gr ON gr.GradeID=p.GradeID
JOIN Form f ON gr.FormID=f.FormID
JOIN SizeUnits su ON gr.SizeUnitsID=su.SizeUnitsID
JOIN Sizes sz ON gr.SizeID = sz.SizeID
JOIN Packages pa ON p.PackageID=pa.PackageID
WHERE oi.OrderID=3
------------------------------------------code---------------------------------------
Any ideas? Thanks in advance.

Hey guys,
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.

Hi, Guys
I read a lot of your post about the mobile device connecting SQL Server. I try to solve my problem, but i still in trouble of Mobile database application.
The following is my development enviroment
Visual Studio .net 2005
Sql Server 2005
Windows CE.Net 4.2
Microsoft ActiveSync 4.2
First i can run some simple application on the Mobile Device( Symbol MC9060G Mobile Device), all the connection between develop PC and Mobile Device is fine. All the develop SDK for the Mobile device without problem.
Secont, i can develop a simple normal windows database application, work fine, can get data from SQL Server 2005. the connection to database server is fine.
I used VS2005 develop a simple database with DataGrid on the form( all the code generated by the VS 2005), when run the program, got error at " int returnValue = this.Adapter.Fill(dataTable)"
error "PlatformNotSupportedException". I don't know what's going on.
I think the connection to the database no problem. Maybe the Mobile device has problem. I insatlled sql.ppc.wce4.armv4.cab file to mobile device.
Can someone help me out?
Thanks.

I have a Fujitsu-Siemens LOOX 520 running WM 5 version 5.1.70 on which I am trying to create a Server 2005 Mobile database.
I have installed the following files on the Pocket PC after a hard reset to make sure the unit was in its vanilla state:
NETCFv2.wm.armv4i.cab
sqlce30.dev.ENU.ppc.wce5.armv4i.CAB
sqlce30.ppc.wce5.armv4i.CAB
sqlce30.repl.ppc.wce5.armv4i.CAB
All the files appeared to succesfully install. Connecting to the device in VS2005 works with no problems. Creating a small test app in VB.NET and running it on the device works no problems, so the device is satisfactorily connected to VS2005.
My problem is this:
When I try to create an SQL Server 2005 Mobile database on the device using Add Connection under the Data Sources window in Visual Studio 2005 Professional (RTM version), I get the following error:
"Microsoft SQL Server 2005 Mobile Edition and/or .NET Compact Framework v2.0 is not properly installed on your mobile device or the device is not responding."
Trying the same thing in Microsoft SQL Server Management Studio gives the same error, but a little bit of extra information:
"Microsoft SQL Server 2005 Mobile Edition and/or .NET Compact Framework v2.0 is not properly installed on your mobile device or the device is not responding. (SQL Server Mobile Edition ADO.NET Data Provider)"
As far as I can see, everything IS installed OK, so why is VS2005 not working?
Thanks for any help.

hi,
Can I write a dll(or share the same code) that works on both Mobile device and pc? Since we are using compact edition, we are hoping we can write some common module with the same code that could works on both mobile device and pc platform. I noticed the reference is the same, System.Data.SqlServerCe.dll 3.0.
Another question is, we already have a module for SQLCE2.0, with .net CF1.0. Now, we will start to use compact edition, should we just update on the 1.0 one, or we have to write a different one based on .net CF2.0? Can I use compact edition in CF1.0 dll?
Thanks.

Hiya,
I have a project that requires that I filter certain data going to the mobile device via the publication based on user selected value on the mobile device. (Filter by location based on the selection of the location on the mobile prior to syncronization).
Now, our current authentication model is Windows Authentication, and changing that to Username based authentication is not feasable, and using the users account to pass that value to the database is the only way I can think of to do this... (Then filter based on username)
But then I thought that there has to be another way - such as passing a variable or parameter to the sync request during or before syncronization... Is this possible? If I could query the data being sent back up to the server, for instance, I could do so to retrieve the value I need.... Any ideas?
Any help appreciated!!
