Well not yet anyway but I think in delaying a problem:
Im focusing on versioning problem. I have two 64 bit development systems. On both systems I have VS2012 which installs sqlCe V4.o. Neither of the system run this software. I also have a beloved old V3.5 Database system that I call regularly. Is there are a problem with sqlCe version mismatches? Come to think of it the I've seen no problem.
V3.5 system runs all the time with VS2012 running while sqlce is down. Would it make a difference if I brought the sqlCe server up and developed while not running the v3.5 system? What would happen were the sqlCe system was brought up while the other sqlCe system were running?

Hello,
I developped an .Net CF 3.5 application for Windows CE 6 on Psion ARM4 device. I use SQL Server 3.5 SP2.
For deploiement, I used the .cab files sqlce.wce5.armv4i.CAB, sqlce.repl.wce5.armv4i.CAB, sqlce.dev.FR.wce5.armv4i.CAB.
Is there a specifique build of SQL Server 3.5 CE for Windows CE 6 ?
Best regards.

OK, I have a WindowsForms application that uses a SQLCE for user data storage. I also have an Access Database (On network) that I would like to use as a data source. I am looking to sync a table from that access database to a table in the SQLCE database.
Is this possible without looping through all of the data?
It would be cool if I could query the Access database into a dataset object, and merge the two with one statement...
Thanks,

Dear all,
i'm using c# and sqlCeServeur. I've got a terrible error in my programm : The column name is invalid [node name (if any), column name = ProteinesBrutes]. As you can see, there aren't any space in my column name. Should i just put my computer in the trash ? x)
Thanks for all,

I want to delete a record from a SQL Server CE table.
There are 3 tables scripts, options and results. I would like to remove a record from the results table. The where clause contains dynamic information which retrieved via other queries to different tables in the same database. These queries work fine and deliver
the desired data.
The Compact server is a clone of a remote table created using the sync framework. The same query to the remote table works fine.
The error I get is:
There was an error parsing the query. [ Token line number = 1,Token line offset = 10,Token in error = from ]
The code that throws the exception is as follows:
Dim connLoc As SqlCeConnection = New SqlCeConnection(My.Settings.ConnectionString)
connLoc.Open()
Dim strDel As String = "Delete r from ResultsTable r inner join OptionsTable o ON o.TestName=r.TestName inner join ScriptTable c ON r.TestName=c.TestName WHERE r.TestName = '" & ds1Loc.Tables(0).Rows(0)(1) & "' AND [Index] = '" & lstIndex & "'"
Dim cmdDel As SqlCeCommand = New SqlCeCommandcmd
Del.CommandText = strDelcmdDel.Connection = connLoccmdDel.ExecuteNonQuery()
The values held in ds1Loc.Tables(0).Rows(0)(1) and lstIndex are
correct so should not be the problem.
I also tried using parameterised queries
Dim strDel As String = "Delete r from [ResultsTable] r inner join [OptionsTable] o ON o.TestName=r.TestName inner join [ScriptTable] c ON r.TestName=c.TestName WHERE r.TestName = @TestName AND [Index] = @lstIndex" Dim cmdDel As SqlCeCommand = New SqlCeCommand
cmdDel.CommandText = strDel
With cmdDel.Parameters .Add(New SqlCeParameter("@TestName", ds1Loc.Tables(0).Rows(0)(1))) .Add(New SqlCeParameter("@lstIndex", lstIndex)) End With
cmdDel.Connection = connLoc
cmdDel.ExecuteNonQuery()
I have tried replacing the "=" with "IN" in the the WHERE clause but this has not worked.
Is it the join that is causing the problem? I can do a select with the same search criteria and joins from the same database.
Also this query works with SQL Server. Is it perhaps that SQL CE does not support the Delete function the same as SQL Server 2008? I have been looking at this for a while now and cannot find the source of the error. Any help would be greatly appreciated.
OK, I want to use the BindingSource.AddingNew event to create a new database row and automatically fill in some of the feilds before the user enters in the data. For example, I would like to fill in an automatically generated id...things like that. The feilds that I enter in manually the user will not have access to on the form.
However, I don't know how to create a new row and assign it to the e.NewObject of the AddingNewEventArgs event handler.
Any help is greatly appreciated. I want my routing to look something like this, but it's not working and I can't think of an alternative.
Public Sub VenderBindingSource_AddingNew(ByVal sender as Object, ByVal e as AddingNewEventArgs) Handles VenderBindingSource.AddingNew
' get error, can't just create a new row
Dim theNewRow as New DataRow()
theNewRow.Row.Item(0) = 39233
e.NewObject = theNewRow
End SubThanks,

</dir>And in the event viewer of the IIS server i get

It looks like that server could not comunicate with my device.
Could someone help me to solve this mistery? Thanx

HI
How to create an sql server compact database(sdf file) from sql server 2008 database.I want to do this one programatically using CSharp or SQL. Could you please help me on this?
I am trying to use SQL Server CE in my MVC 4 web app. I have a class library and I have added the reference to System.Data.SqlServerCe.dll (V4)
The code to create the SDF is:
String connString = "Data Source=|DataDirectory|\HomeController.sdf"; SqlCeEngine engine = new SqlCeEngine(connString); engine.CreateDatabase();
Which create a SDF with no problems
Next I try to work with the SDF like this:
XmlDocument xmlDoc = new XmlDocument();
XmlTextReader xmlReader = new XmlTextReader(ConfigurationManager.AppSettings["ApplicationSettingsPath"] + @"\CreateHomeControllerDatabase.xml");
try
{
xmlReader.Read();
xmlDoc.Load(xmlReader);
foreach (XmlNode jobNode in xmlDoc.SelectSingleNode("Jobs"))
{
//TODO look at the old version on my old machine and debug this to see what the issue is
DataContext db = new DataContext(DATABASE);
db.ExecuteCommand(jobNode.InnerXml.Replace("<![CDATA[", String.Empty).Replace("]]>", String.Empty).Trim());
}
}
catch (Exception ex)
{
//ErrorHandler.ErrorDelegate.LogError(ex); TODO
}As soon as it it hits DataContext db = new DataContext(DATABASE);I get the exception Cannot open '|DataDirectory|\Test.sdf'. Provider 'System.Data.SqlServerCe.3.5' not installed.
First things that looks strange is why is it asking for 3.5 when I added the 4.0 instance of the dll? I have not installed the SQL CE 4.0 on my machine as the intention of using CE was to easily install this on a client by just adding the dlls. I have added the other dlls in that folder where possible but it just errors.
Any ideas please?

I've installed & uninstalled MS SqlSever 2005 in my system (OS - Windows 8). When am try to access my photo gallery on desktop, I'm getting above mentioned error. How come photo gallery is dependent on MS SqlServer 2005 compact edition? Now, I've installed & using MS SqlServer 2008.
I am trying to get a better understanding of what the benefits would be for using a SQL Server Compact database as opposed to a Jet/ACE database for the following situation:
- New WPF application - will be implemented in Visual Studio 2010 or 2012
- Single user - only one user of the application at a time
- Fairly complex datamodel in terms of number of tables and their relationships (100+ tables)
- Reasonable data volumes, a few tables with 100,000+ rows but most with rows in the thousands or less
Given this type of application, what are the benefits with SQL Server Compact Edition in the following areas (and any other that you would say are relevant):
- Performance
- Stability / Integrity
- Long term support (from Microsoft)
I am new to Entity Framework and SQL Server Compact. I'm trying to use the "model first" method to create an Entity Framework 5.0 model and an SQLCE database. After creating the model, I right-click the design surface and chose "Generate database from model" from the context menu. I was prompted for a database connection and selected SQL Server Compact and created a new database (the .sdf file was created with no tables and appears in Database Explorer). When I click Finish in the Generate Database wizard, a DDL script is created (Model1.edmx.sqlce) and opened in VS.
The tutorial I am following says the next step is to right-click on the script and choose Execute SQL from the context menu. The problem is that there is no Execute SQL choice in the menu. If I right-click on the open window for Model1.edmx.sqlce , my choices are:
I also see that the icon for Model1.edmx.sqlce in Solution Explorer is the one for an unknown file type. If I right-click on the item in Solution Explorer there is still no Execute SQL option.
It appears that I am missing an association between the sqlce filetype and some component that is supposed to run the script to create the SQLCE database. Does anyone know what I need to do to get this to work?
We are using SQL CE as a subscriber in a merge replication topology. Occasionally, users get the following error when trying to sync with the publisher:
I get the same error when I try to connect to the .sdf directly through SSMS. I am under the impression that this is caused by .sdf corruption. Is this true? How can I tell? I've seen the C# code that allows you to verify corruption, but does anyone know of a utility I can use so I won't have to get developers involved? Is there any other info I can provide her that will help diagnose the problem?
Thanks in advance,
Clint
