System.Data.SqlServerCe Desktop Vs Compact Framework

Aug 7, 2007

How can I tell if the System.Data.SqlServerCe assembly I am referencing is meant for Desktop use as opposed to Compact development? We are using NUnit as our testing framework and I get the following error when I attempt to execute nunit-console on my test fixture referencing SqlServerCe:

System.IO.FileLoadException : 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) ---->

System.IO.FileLoadException : Could not load file or assembly 'System.Data.SqlServerCe, Version=3.0.3600.0, Culture=neutral, PublicKeyToken=3be235df1c8d2ad3, Retargetable=Yes' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)


The unit tests run fine from inside of Visual Studio using the Resharper Unit Test Runner...

How To Find Correct System.Data.SqlServerCe.dll In Desktop Project?

Feb 2, 2008

Hi,
I am working on a .dll which need to access .sdf ( sql server mobile db). In my project, I added a reference "System.Data.SqlServerCe.dll". The dll is located in C:Program FilesMicrosoft Visual Studio 8Common7IDE.
I am able to compile the project. Then I created a Unit project for this dll file. In Unit project, I added the same reference.
Now the magic things happen. The compiling was failed. I got "Error 1 The type 'System.Data.Common.DbConnection' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. C:VS2005MobileDBUnitMobileDBProjectUnitMobileDB.cs 50 13 UnitMobileDBProject".

I don't understand how come the same .dll could pass in a dll project but failed in unit test project. And I never saw the System.Data.SqlServerCe display in ".Net" Section of Add reference. But in my office, I installed same version of VS2005 for software tester. I could see the System.Data.SqlServerCe display in the ".Net" section of Add Reference.

Please help me to fix this problem. Thanks.

Compact Framework SqlClient Classes Don't Actually Inherit From System.Data.Common.Db* Classes?

May 23, 2007

As you all know, in Framework 2.0 on the desktop platform you have the convenient "abstract" Db* classes that can be used to write more generic code. For instance System.Data.SqlClient.SqlConnection inherits from System.Data.Common.DbConnection, and so forth. Now the docs clearly say that this applies to the corresponding classes in the Compact Framework. And i have seen this implied by other web searchs I've done. However this does not seem to be the case -- or, I'm missing something somewhere.

The following simple code on the desktop platform compiles OK:

using System.Data;
using System.Data.Common;
using System.Data.SqlClient;
DbConnection conn = new SqlConnection();

However it doesn't compile in a compact framework project: "Cannot implicitly convert type 'System.Data.SqlClient.SqlConnection' to 'System.Data.Common.DbConnection'".

Reflector also indicates that the Compact Framework class doesn't inherit from DbConnection.

OK, so am I missing something here, or what was the reason that Microsoft did it differently??

Problem With System.Data.SqlServerCe.dll

Oct 11, 2006

I believe I've encountered a compatability problems with Visual Studion CF 2, specifically with the System.Data.SQLServerCE reference when trying to run (in debug mode - Pocket PC 2003 emulation). The environment is configured as follows:

Visual Studio 2005 - Compact Framework 2.0.50727

Microsoft SQL Server 2005 Mobile Edition

The (VB) project includes the following references:

System.Data.dll V2.0.000 from Program FilesMicrosoft Visual Studio 8Smart DevicesSDKCompact Framework2.0V2.0WindowsCE

System.Data.SqlServerCE.dll V3.0.5214.0 from Program FilesMicrosoft SQL Server Mobile EditionDeviceMobileV3.0

The IDE does not sense any problems with the following code until I try to run it in debug mode using the Pocket PC 2003 emulator. The code :

Imports System

Imports System.IO

Imports System.text

Imports System.Data

Imports System.Data.SqlServerCe

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

MsgBox("Will Test SQL")

Call testSQL()

End Sub

Private Sub testSQL()

Dim strConn As String = "Data Source = Test.sdf; Password = <password>"

Dim CEEngine As New SqlCeEngine(strConn)

CEEngine.CreateDatabase()

CEEngine.Dispose()

Dim Conn As SqlCeConnection = Nothing

Conn = New SqlCeConnection(strConn)

Conn.Open()

Dim cmd As SqlCeCommand = Conn.CreateCommand

cmd.CommandText = "CREATE TABLE MyTable (col1 int, col2 ntext)"

cmd.ExecuteNonQuery()

Conn.Close()

Exit Sub

ErrHandler:

MsgBox(Err.Number.ToString)

MsgBox(Err.Description.ToString)

End Sub

In the debugger, the program terminates at Dim CEEngine As New SqlCeEngine(strConn). The message displayed is

Can't find PInvode DLL 'sqlceme30.dll'

I've tried referencing a different version of System.Data.SqlServerCE.dll (from Program FilesMicrosoft SQL Server90ToolsBinnVSShellCommon7IDE but the program will not even deploy to the emulator with this reference.

I encounter a Deployment/and or registration failed wit error : 0x8973190e - There is not enough space on the disk.

What versions of the following should be used?

System.dll

System.data.dll

System.Data.SqlServerCe Versions

Oct 2, 2007



Hello,

I've inherited a .NET CF 2.0 application at work that uses SQL CE, and as I'm digging into the build process, I'm getting confused about which version of SQL CE that is being used.

The project references System.Data.SqlServerCe (no hint path, just from wherever VS 2005 has it). When I look at the assembly in my project, the version shows up as 3.0.3600.0, but when I browse to the DLL's location on my hard drive (C:Program Files (x86)Microsoft Visual Studio 8SmartDevicesSDK\SQL ServerMobilev3.0System.Data.SqlServerCe.dll), right click the DLL and check the properties, the version shows up as 3.0.3600.0.

In our installation package, we install three SQL CE Cabs:
sqlce30.dev.ENU.ppc.wce5.armv4i.CAB
sqlce30.ppc.wce5.armv4i.CAB
sqlce30.repl.ppc.wce5.armv4i.CAB

When installed on the device, the Remove Programs dialog shows as "Microsoft SQL Mobile 2005..." is installed. We keep the cabs in a seperate location so they are not just pulled from anywhere on the hard drive.

However, when I install the same CAB files located at:
C:Program Files (x86)Microsoft Visual Studio 8SmartDevicesSDKSQL ServerMobilev3.0wce500armv4i, the device shows "Microsoft SQL Mobile 2005 Compa...." is installed.

In my Add References dialog, System.Data.SqlServerCe has version 3.0.3600.0, runtime v2.0.50727

Some questions:
1. Is the version 3.0.3600.0 the same between 3.0 and 3.1?
2. Given a System.Data.SqlServerCe DLL, how can I tell if it is the 3.0 or 3.1 version?
3. When upgrading my project to use 3.1, is it enough simply to upgrade my build environment? Or should I need to change the references in my project? (It appears that the 3.1 DLLs have been placed into the default locations where VS 2005 is pulling them from). I'm using VS 2005 SP1 on Vista x64.


Thanks

System.Data.SqlServerCE.dll Reference Causes Error ...

Feb 15, 2007

Hello All ...

I
am attempting to create a program that will run on the PocketPC 2003
environment. I have upgraded Visual Studio to SP1, I have installed SQL
Server Compact Edition on my development machine and I have installed
SQL Server Compact Edition Tools For Visual Studio on the development
machine.

I have created a new project Visual Basic - Smart
Device - Pocket PC 2003. I have created a form for user input. I build
and deploy the form to the Symbol Pocket PC to test - no connection to
data and it works.

I then add a reference to
System.Data.SqlServerCE.dll and rebuild and redeploy the application to
the handheld. When I attempt to open the form I receive the following
error:

psmPocket.exe
NotSupportedException
System.Drawing.Bitmap

at
System.Resources.ResourceReader.LoadObjectV2() at
System.Resources.ResourceReader.LoadObject() at
System.Resources.RuntimeResourceSet.GetObject() at
System.Resources.ResourceManager.GetObject() at
System.Resources.ResourceManager.GetObject() at
pmsPocket.frmSetSOPType.InitializeComponent() at
psmPocket.frmSetSOPType..ctor() at
System.Reflection.RuntimeContructorInfo.InternalInvoke() at
System.Reflection.RuntimeContructorInfo.InternalInvoke() at
System.Reflection.ContrcutorInfo.Invoke() at
System.Activator.CreateInstance() at MyForms.Create__Instance__() at
MyForms.get_frmSetSOPType() at psmPocket.SetSOPType.Main()

Now
the confusing part is that I haven't changed any of the forms or the
code behind the forms, I have simply added the reference to the project.

Any idea why adding the reference to System.Data.SqlServerCE.dll would cause the system to start generating these errors?

I've
checked, the install process has loaded the .NET 2 framework to the
handheld. And as indicated at the beginning of this message, the
application showed the form prior to my adding the reference.

Thoughts?

Thanks ...

How To Use Db Provider Factories With System.Data.SqlServerCe

Jul 7, 2007

I'm using SQL Server Compact Edition, but in the future I would like to be able to switch to another SQL Server Edition or even a different database. To achieve this, Microsoft recommends using DB Provider Factories (see: Writing Provider Independent Code in ADO.NET, http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=674426&SiteID=1).I enumerated the available data providers on my PC with:



Code Snippet

System.Reflection.Assembly[] myAssemblies = System.Threading.Thread.GetDomain().GetAssemblies();

The important entry is:"SQL Server CE Data Provider"".NET Framework Data Provider for Microsoft SQL Server 2005 Mobile Edition""Microsoft.SqlServerCe.Client""Microsoft.SqlServerCe.Client.SqlCeClientFactory, Microsoft.SqlServerCe.Client, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"When executing:




Code SnippetdataFactory = DbProviderFactories.GetFactory("System.Data.SqlServerCe");


I got at first this error run time message: Failed to find or load the registered .Net Framework Data Provider.I added a reference to "Microsoft.SqlServerCe.Client" at C:ProgrammeMicrosoft Visual Studio 8Common7IDEMicrosoft.SqlServerCe.Client.dll and the program runs.Of course, it uses "Microsoft.SqlServerCe.Client" instead of "System.Data.SqlServerCe". Laxmi Narsimha Rao ORUGANTI from Microsoft writes in the post "SSev and Enterprise Library" that "Microsoft.SqlServerCe.Client" is not meant to be used and that we should add the following entry to the machine.config file:




Code Snippet<add name="SQL Server Everywhere Edition Data Provider" invariant="System.Data.SqlServerCe" description=".NET Framework Data Provider for Microsoft SQL Server Everywhere Edition" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />


After changing the code to:


Code Snippet

dataFactory = DbProviderFactories.GetFactory("Microsoft.SqlServerCe.Client");

I get the same error message as before, even after adding a reference to "System.Data.SqlServerCe" at C:ProgrammeMicrosoft Visual Studio 8Common7IDESystem.Data.SqlServerCe.dll.Any suggestion what I should do ? Just use "Microsoft.SqlServerCe.Client" ? Anyway, I don€™t like the idea that I have to change the machine.config file, since I want to use click once deployment.

System.data.sqlserverce.dll Problem -- Its Very Urgent

Dec 18, 2006

hi,

 We are facing a problem with compact framework 1.0 and SQL CE on windows mobile 5.0 smart phone (Motorola Q).

The application was build for Windows Mobile 5.0. When we use €œSystem.Data.SQLServerCE.dll€? from €œC:Program FilesMicrosoft Visual Studio 8SmartDevicesSDKSQL ServerMobilev3.0€? in compact framework 2.0 it works fine.

Since Motorola Q has .Net Compact Framework 1.0 we need to port same application to compact framework 1.0. There is similar DLL in "C:Program FilesMicrosoft Visual Studio 8SmartDevicesSDKSQL ServerMobilev2.0" but it is not working, it gives runtime error missing method at very first line of code SqlCeEngine _eng = new SqlCeEngine().

 

Thanks & regards,

Rashmi

SELECT @@IDENTITY Using System.Data.SqlServerCe?

Mar 29, 2007

Hi! I am having a problem getting the inserted id from a table.

Here is the table:

/*********************** Companies **********************************/
CREATE TABLE Companies(
CompanyId int IDENTITY(1,1) PRIMARY KEY,
Description nvarchar(30) NOT NULL
)
GO

When I type SELECT @@IDENTITY in SQL Management Studio after a successful insert, it works fine. However, in code (System.Data.SqlServerCe), I get an error using this code:


SqlCeCommand cmd = conn.CreateCommand();

cmd.CommandText = sql;

cmd.CommandType = System.Data.CommandType.Text;

ret = (int)cmd.ExecuteScalar();

I saw a thread with this solution, but do I really have to go to this trouble?

DECLARE @MyTable table
( MyIdentity int )
INSERT INTO Employees ( FirstName, LastName )
OUTPUT inserted.EmployeeID INTO @MyTable
VALUES ( 'Bill', 'Smith' )
SELECT MyIdentity
FROM @MyTable



scope_identity does not seem to work either. Am I missing something?



Thanks!

Limit On Blob/image Data Type In SQL Compact 3.5 SP 1 BETA For ADO Entity Framework?

Apr 5, 2008

Hi! I tried to save some image data, but it get truncated at 8000 (the table column is defined as Image). I then wrote a converter to try ntext-datatype instead, but it gets truncated at 4000.


Error message:
System.Data.SqlServerCe: @3 : String truncation: max=4000, len=4168


The code uses only ADO entity framework for database access. Is there a way to store binary data larger than 8000 bytes? I am running SQL Compact 3.5 sp 1 BETA.

Reference To Data.System.SqlServerCe In VS2005 Does Not Install CE 2.0 To Emulator/PDA

Feb 3, 2006

We have a Compact Framework 1.1 application that uses Sql Server CE 2.0. In VS2003, a reference to System.Data.SqlServerCe causes the Sql Server CE dlls and Query Analyzer to install to the Emulator or PDA.

I am currently converting the application to Compact Framework 2.0, but we are not upgrading to Sql Server Mobile (yet). However, the reference to System.Data.SqlServerCe, in VS 2005, no longer causes Sql Server CE to install to the PDA/Emulator.

There is a difference in the build outputs between VS2003 & VS2005. In 2003, System_SR_enu.cab, sqlce.wce4.x86.cab & sqlce.dev.wce4.x86.cab are copied & lanuched. In 2005, only System_SR_enu.cab is copied... no launch.

Any ideas? Reinstall VS2005?

Could Not Load File Or Assembly 'System.Data.SqlServerCe, Version 3.5.0.0

May 8, 2008

We just upgraded our applications from VS 2005 to VS 2008 and discovered we had to convert our SQL Server CE databases. So I did that. I then included the sqlce...35.dlls in the application directory on my test computer as well as the System.Data.SqlServerCe.dll version 3.5.

sqlceca35.dll
sqlcecompact35.dll
sqlceer35EN.dll
sqlceme35.dll
sqlceoledb35.dll
sqlceqp35.dll
sqlcese35.dll

When I run the app and it tries to load the System.Data.SqlServerCe.dll I get the following error:
System.IO.FileLoadException: Could not load file or assembly 'System.Data.SqlServerCe, Version 3.5.0.0...or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.

We have the application targeting the .NET Framework 2.0 and need to keep it that way for awhile.

Any ideas on how to resolve the error?

Failed To Find Or Load The Registered .Net Framework Data Provider When Using SQL Server Compact Edition

Jul 3, 2007

Hello



I have recently downloaded Orcas beta VS product and had no previous version of VS before. The install went clean and I have been able to generate Window apps and web apps with very little issues; however, I have one issue with running a web app using the "view in browser" option for checking an aspx page for validity. If I use the default Northwind database provided and generate an aspx form using the "DataSet" toolbox widget, the tool prompts for the datasource etc. required to generate the required code. I can select the Northwind database and select the desired columns from one of the tables. Once completed, I build the project (clean build) and then select the "view in browser" option to verify the results. The result is an error page indicating a server error ->
Failed to find or load the registered .Net Framework Data Provider.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Configuration.ConfigurationErrorsException: Failed to find or load the registered .Net Framework Data Provider.



I created on odbc connection to an iSeries(as400) box and was successfull in displaying the table on the webpage! I looked into the web.config file and it appears that all the required XML data is present. Any help would be appreciated as I am fairly green when it comes the .NET world.

System.Data.SqlServerCe.SqlCeCommand Has A Bug Related To SqlCeParameter Order That Causes Exceptions.

Jan 11, 2008

I came across a frustrating bug last week. Basically, whenever I tried to execute almost any sql query with unnamed parameters (i.e. using "?" instead of "@param_name" in the SQL text), an exception would be thrown.

After trying lots and lots of things and navigating my way through the internals of System.Data.SqlServerCe.dll, I discovered that the method System.Data.SqlServerCe.SqlCeCommand.CreateParameterAccessor(...) has a bug.

The bug is that the private arrays "parameters" and "metadata" are ordered differently, yet at one point in CreateParameterAccessor(...) they are compared using the same index. Here are the two lines:
p = this.parameters[ i ];
and
MetaData info = metadata[ i ]
and then the column data types of "info" & "p" are incorrectly compared in a later method, ValidateDataConversion(...).

So take a step back... how are they ordered differently? From observation, I concluded the following:
The "parameters" array is ordered exactly in the order that the DbParameter's were added to the DbCommand object.
The "metadata" array is ordered according to the column order of the table in the database.


So what causes the exception? Well, CreateParameterAccessor(...) passes data types from two different columns (one type taken from parameters[ i ] and the other from metadata[ i ]) on to SqlCeType.ValidateDataConversion(...). And, of course, if they differ (e.g. one column is of type DateTime and the other is a SmallInt), an exception is thrown.
I've found two workarounds, and both seem to work well.
The first is to name the SqlCeParameters (e.g. "SELECT ... WHERE id=@id"). This causes the buggy branch of code to be completely bypassed.

The second is to add the SqlCeParameters in the exact same order as the columns exist in the table you are accessing. Note, I do *not* mean the order that you select the columns (e.g. "SELECT column1, column2, ..."). I mean the actual order of the columns in the database.

I've included my setup and a stack trace below to help if it can.

My setup is:
.Net CF 3.5
SqlServer CE 3.5
Visual Studio 2008
Deployed to Pocket PC 2003

Here is the stack trace (note the variables passed to ValidateDataConversion):

System.Data.SqlServerCe.dll!System.Data.SqlServerCe.SqlCeType.ValidateDataConversion(System.Data.SqlDbType expectedType = DateTime, System.Data.SqlDbType actualType = SmallInt) + 0x4a bytes

Referencing To System.Data.SqlServerCe Causes Large Files To Deploy To Emulator

Dec 8, 2006

Hello everyone,

This is my first time posting here, I hope this questions has not been asked before. I tried to search for it but I came not with nothing.

Recreating the error :

I am using VS2005. I created a Pocket PC 2003 project.
I have downloaded the SQL Server Compact Edition and installed it. I get the System.Data.SqlServerCe.dll file from the installation directory.
I reference to that DLL using Add Reference in VS2005.

Build it. In the Bin folder, a long list of files suddenly appears.

System.data.dll
System.data.oracleClient.dll
system.web.dll
system.enterpriseservices.dll
system.enterpriseservices.wrapper.dll
system.transactions.dll
and the rest of your original files in Bin

The worst of it all, all of these files are deployed into the Emulator! Causing it to run out of memory and unable to deploy.



Something is not right here, I just cannot figure it out! If this happens, each mobile devices can hold one applications. Thats not the way it should be, right?

If you have solved this before, do help. I am at my wits end at the moment.

Thanking you in advance.

Sincerely,

Install Error System.data.sqlserverce Not In Global Assembly Cache

Nov 2, 2006

I have built a small application in vs2005 (vb) using system.data.slqserverce building

in the mobile sql engine into my app. I intend to run this on desktop. The app

works fine on my development laptop machine, when i publish it (to a hard disk folder) and run it on another laptop, i get:

'unable to install or run the application. The application requires that assembly system.data.sqlserverce version 9.0.242.0 be installed in the Global Assembly Cache (GAC) first.'

This is my first app in .net so not sure what this means.

I thought all i had to do was reference the file (which i have done in the project) and

VS would take care of stuff like this? Framework 2.0 is installed on the target machine.

Hope im in the right forum for this! if not i apologise



Any help most appreciated.

Error From System.Data.SqlServerCe.SqlCeCommand.ProcessResults() - ** No Exception Message Returned **

May 7, 2008

I have an app running Windows CE 5.0 and SqlServerCE 3.0. Occasionally, one of the production units will throw an exception with the following stack trace but no exception message:

Exception Msg:

Stack Trace: at System.Data.SqlServerCe.SqlCeCommand.ProcessResults()
at System.Data.SqlServerCe.SqlCeCommand.CompileQueryPlan()
at System.Data.SqlServerCe.SqlCeCommand.ExecuteCommand()
at System.Data.SqlServerCe.SqlCeCommand.ExecuteReader()
at System.Data.SqlServerCe.SqlCeCommand.ExecuteReader()
at XX.MobileApp.frmXXX.LoadData()


This is not something that I have been able to reproduce in our shop. I even take their database and run it here in our shop with out such errors. Does anyone know some possible causes for this error?


Sorry, I don't have more info to give becuase this is all I have to work with since I cannot reproduce in our shop. If the exception object exposes a property for the HResult, I would be able to provide that.

I appreciate your repsonses.

SqlServerCEResultSet To XML?? In Compact Framework 3.5?

Mar 26, 2008

you can, with a dataset  do something like myDataSet.WriteXml(m_XmlFile, XmlWriteMode.IgnoreSchema) and get XML for a record....
 is it possible to do something like that with SQLserverCeresultset?
i know i could probably loop thru the columns and create the xml manually...  but using somethinglike writexml will give better performance?
 right now im not using anything from the XML class... from my previous exp with using XML classes on the Compact framework gives slow performance...

Can't P/Invoke Sqlceme35.dll With Headless Compact Framework

May 19, 2008

I am aware of the many posts that have addressed this issue in the past - I resolved this issue many months ago when it first happened to me. However, I have recently created a headless version of my Windows CE 6.0 based project that uses the Headless versions of the Compact Framework and this problem has suddenly re-surfaced. As in my UI equipped versions, the SQL CE cab files are copied to the device and have been installed. I have also tried copying the sqlceme35.dll to the application folder. The only real difference I can see is that the device is using the headless version so I suspect that there may be some incompatibility.

Has anyone successfully deployed a SCQL CE aplication to a headless device and if so were there any special steps that had to be taken to make it work?

Thanks

Cannot Connect To A Named Instance Of SQL Server From Compact Framework 2.0

Mar 14, 2008

I have two instances of SQL Server on the same PC:

Default instance: SQL Server 2000
Named instance with name €œMS2005€?: SQL Server 2005.
Also I have another SQL Server 2005 on another PC.

I created a .NET 2.0 Compact Framework application that connects to the database and executes simple query. This application can connect to any instance of the SQL Server when it is executed on the PC (not on the server). But the problem is that when I try to execute the application from the windows CE 5.0 device, the application can only connect to the default instance (SQL 2000 and 2005) and can not connect to the named instance (Name: MS2005).
Is it some kind of limitation of the SqlClient library for the compact framework?

Below are the code and connection strings:

string connectionString = €œServer=1.1.1.1;Database=DB1;Uid=sa;Pwd=€?
string connectionString = €œServer=1.1.1.1\MS2005;Database=DB1;Uid=sa;Pwd=€?

using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open(); //This is the point where exception is generated

using (SqlCommand command = connection.CreateCommand())
{
command.CommandText = "select count(*) from users";
object result = command.ExecuteScalar();

Console.WriteLine("Result: [{0}]", result);
}

connection.Close();
}


Thank you for your time and advice.
