Changing Working Database From SQL To SQL Mobile

Nov 9, 2007

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?

Thanks

SSIS: Changing URL In HTTPConnectionManager Not Working?

Dec 3, 2007

I've been building a prototype using Webservices (coded in .NET) and SSIS to move data from our order/fulfillment system to our accounting system. I have struggled a bit with SSIS's WebService Tasks; but, finally have a package that runs locally that calls a web service and loads the data into SQL Server. I tried to move this to our server, I modify the HTTPConnection Parameter to the Product WS URL and the web service task fails with an "Unable to Connect to Server" error.

So, I decided to try running the production WS in my local (development) SSIS. I change the HTTP Connection URL, save, rebuild and run. The job runs successfully - against my LOCAL Web Service. It did not recognize the change or is somehow cached.

How do I get it to run against my Production Web Service???

Thanks.

Changing SQL 2005 Password Policy Not Working

Feb 19, 2007

I have modified the Security Settings>Account Policies>Password Policy on my PC as follows:

Minimum password length: 10 characters

Password must meet complexity requirements: Enabled

However, when creating a login within SQL Server 2005, which does not adhere to the amended policy, this does not seem to be taken into account:

CREATE LOGIN testlogin WITH PASSWORD='a',

DEFAULT_DATABASE=[master],

DEFAULT_LANGUAGE=[us_english],

CHECK_EXPIRATION=ON, CHECK_POLICY=ON

have tried restarting the SQL Server and rebooting the PC, but this does not solve the problem.

SQL Server Mobile 2005 Merge Replication Problem On Windows Mobile 5.0

Aug 8, 2006



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

SQL Mobile 2005 Replication - SQL Mobile DLL Could Not Be Loaded - Error 28559

Jun 15, 2006

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.

Problem Using SQL Server Mobile 2005 With Windows Mobile 5 Application

Mar 23, 2006

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.

Cannot Build SQL Server Mobile Solution For Windows Mobile 5

May 18, 2006

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?

Error #25123 A Sql Mobile DLL Could Not Be Loaded. Reinstall SQL Mobile.

Sep 8, 2007

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.

SQL Server Mobile Tutorial And Getting Proper Mobile DB Installation

Apr 24, 2006

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

How To Transfer Database To Mobile Device?

Dec 23, 2006

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!

Create Mobile Database From Xls, Csv, Text Or Mdb

Nov 28, 2006

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

Problem With Updating A Mobile Sql Database

Sep 10, 2007

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

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.

Updating A Sql Database From A Mobile Device

Aug 19, 2007

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

Creating A Mobile Application With SQL Server Mobile - FIX

Jul 21, 2006

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.

VS 2005 - VB.NET - Connect To Mobile SQL Database From Desktop PC

Jun 7, 2006

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)

Does anyone have any suggestions?
