Hi,
Can I use SqlCe v3.1 and SqlClient v2.0 in one .net application? (Note: I can't use RDA or replication. SqlClient read and write data in ON-LINE mode, SqlCe store and manipulate with data in OFF-LINE mode.)
can we open a sqlce databse stored on desktop hard disk in desktop application ?

Hi,
I was migrating one of my applications to VS.NET 2008 to start testing the new platform and encountered an error. One of my application requires the use of System.Data.SqlServerCe namespace to create a SQL Server CE database on a desktop machine.
The error is raised when I try to use a SqlCeCommand to insert rows in a table using parameters. If the order of the fields in the INSERT command does not match the order of the fields in which the table was created, an error is raised.
Investigating further, I noticed that the INSERT command was trying to insert the value of a parameter in an incorrect field. For example, the value for the field23 was being inserted into field22.
It looks like the SQL CE engine is rearranging the fields in the INSERT command to match the order of the fields in the table, but forgets to rearrange the parameters of the SqlCeCommand as well.
I give the example codes in the next posts. I will give it in both VB.NET and C#.
For both versions, you just need to create a Windows Application and add a reference to System.Data.SqlServerCe.dll. Insert the corresponding code into the Form1 partial class.
In the example, the constant RaiseError can be set to Boolean.True in order to raise the error. Set it to Boolean.False to execute correctly.
New to VS2005 and I've got a simple WM5 app that runs fine on the emulator, but when I do a deploy to the device and try to run it I get:
'System.Data.SqlServerCE, Version = 3.0.3600.0, Culture = neutral, PublicKeyToken = 3BE235DF1C8D2AD3' or one of its dependencies, was not found.
I have added the *.sdf to the Deploy project and in the dependencies portion of the Deploy project it has the "System.Data.SqlServerCE.dll" listed.
Appreciate any comments or suggestions.
Thanks,
John.
I download the DAAB CF version. However, most of them use SQLCEClient to connect to the database. Is there any DAAB that use SQLClient?
One workaround that I made is I replaced all SQLCEClient objects with the SQLClient objects. I only test one method "ExecuteDataset" and it works so far. However, my question is "does my workaround a good solution?"
Thanks,

I'm attempting to use RDA to synchronize a pocket pc emulator with SQL Server 2005 database by following tutorial http://msdn2.microsoft.com/en-us/library/aa454892.aspx, which uses AdvWorksMobile database that comes with SQL Server 2005.
When get to testing of "To test application features " ( step 4 of the merge replication setup lab ), I am receiving SQLCe Exception errors.
ORIGINALLY, I was able to deploy an application and view the local database on the emulator, but once I clicked "InitSinc" button, I received an error.
"Failure to connect to SQL Server with provided connection information. SQL Server does not" exist, access is denied because the SQL user is not a valid user on the SQL Server, or the password is incorrect.
Found this error listed in Server Agent Errors log http://technet.microsoft.com/en-us/library/ms172357.aspx, but it wasn't very helpful since it doesn't provide any suggestions on fixing the problems.
I am brand new to SQL CE Server , mobile programming and .NET framework in general so please bare with me
All the connections / security settings, etc that were set up were taken from a tutorial so I am not sure what SQLCeServer is complaining about. Reading up on the error on the web didn't help, it all pointed to making sure that the snapshot folder had correct permissions set up. I verified that MACHINENAMEUISR_MACHINENAME guest user had Read rights to the database so I don't think that piece is the problem. Otherwise ,Merge publication has been setup in Microsoft SQL Server Management Studio by following the tutorial.
I am trying to run this sync on my home pc so there should be no issues with any user permissions
I have IIS installed
I did NOT have SQL Server Agent running in management studio at this time
I am trying to run this tutorial on an XP machine, which is my regular home PC so I dont think there are any special networking settings to consider
I am able to hit http://localhost/AdvWorksMobile/sqlcesa30.dll from my pc OK, but when I try to hit it from a cradled emulator ( after replacing "localhost" with "MACHINE_NAME" ), Internet Explorer on the emulator gives me a "Cannot Connect With Current Settings" error message. This part wasn't part of tutorial but decided so not sure if I am supposed to be able to hit it from my emulator..so I am not sure if the fact that I can't hit it is related to the problem.
AFTER STARTING SQL SERVER AGENTin Microsoft SQL Server Management Studio, I killed the application, and after relaunching it, it hits "The Specified table does not exist [Vendor]" error. This time it doesn't even launch first - that is I dont even get to pressing "InitSinc" button. Debugger is showing that this error is hit on the following line in AdvWorksMobile.AddWorksDataSetTableAdapters
int returnValue = this.Adapter.Fill(dataTable);
I am not sure why the errors changed on me after starting SQL Server Agent.
What can I do to fix this connection problem?
Thank you so much for your help!

I am currently upgrading our ppc app (written in .net 2003) to .net 2005 and from sqlce 2.0 to 3.0. The new application runs out memory(storage) when handling lots of data transactions (both in case of using sqlcedatareader, and dataset ). There is no memory leak issue here, sqlce 3.0 simply uses a lot more (3 times more) memory than sqlce 2.0.
Our applicaton runs fine using sqlce 2.0 and .net 2003, but fail due to memory shortage
with the upgrades(which has the same code). Anyone can shed some lights on this issue?
Does anyone have any instructions on how to go about uprading a .sdf file
from sqlce 2.0 to sqlce 3.0?
I found this on an msdn website
(link: http://www.microsoft.com/sql/editions/sqlmobile/upgrading.mspx) but
as you can see its very lacking on detail. (I included the link and content
referring to upgrading the database files so you won't have to go to the link
to see the part referring to upgrading the database.) I tried to run the upgrade.exe on my device but it doesn't explain how you're supposed to point it to the .sdf that you are trying to update. Here is the content on the above web page.
Upgrading Database Files
You can upgrade a database created with an earlier version of SQL Server CE
2.0 to a database created with SQL Server Mobile by using the SQL Server
Mobile Database Upgrade tool (upgrade.exe). The Database Upgrade tool runs on
a smart device.
When you run the SQL Server Mobile Database Upgrade tool, the new SQL Server
Mobile database is created on the smart device. The new database, with the
file name extension .sdf, contains all the data that was in the source
database. You need to reinitialize the upgraded database to continue using it
for replication.
Note: If you are using replication or remote data access (RDA) as a
connectivity solution before upgrading to SQL Server Mobile, you must
synchronize the source SQL Server CE database (subscription database) with
the SQL Server database (Publisher). The reason for synchronizing before
upgrading to SQL Server Mobile is to ensure that any changes that exist in
the tables on the SQL Server CE database are updated on the SQL Server
database, because after the upgrade you must resubscribe or repull using the
new database.
I presently run on my server SQL SERVER CE 2.0 and want to install, in addition on SQL Server 2.0, SQL Server Mobile 2005.
Is there a procedure to have both installed and running on a computer?
Thanks!
Marco

It is possible to upgrade existing SqlCE to Sql 2k5 database? Or just import CE database to import data model structure and data?
View 1 Replies View RelatedMy app is working on my local system with the vs2008 development server. It's an asp.net app and I added the line:
AppDomain.CurrentDomain.SetData("SQLServerCompactEditionUnderWebHosting", true);
So it works fine on my system. But I can't get it to work on shared hosting. I have uploaded all the sqlce 3.5 dlls to the bin directory. I am stuck at the error:
Access to the database file is not allowed. [ File name = ]
There actually is a file name in the connection string, and I set the permissions wide open on App_Data to test this.
What are the .net framework requirements for sqlce 3.5? I can't find this info anywhere.
I know sqlce 3.5 is not recommended for asp.net, but it is not the main site database but is used for a setup database utility to be installed for a windows app.
Hi Experts
I'm facing a weird problem with asp.net application and windows 2000 based client PC having IE 6.0 SP1, i have asp.net web application which have a form that have a facility to search for customer using its ID and application will bring the data from the database that record and users will be able to update the record.
Once updated, then i just want to query data for same customer id, application is not bringing updated record from the database but it showing the old record and once the IE closed and reloaded then it shows the correct record.
The same feature works fine, under windows xp machine having IE 6.0 SP2, that proves that there is no problem with my application or code but its windows 2000 client having problem.
I tried to update the windows 2000 machine with all the patches from microsoft but no success same problem.
Any help on this issue will much appreciated.

Hi,
We have over 1000 terminals running CE 4.2 on an x86 cpu currently using SQLCE 3.1.
We have just upgraded to VS 2008 and found the projects have been upgraded to reference SQL CE 3.5 - this is great, as we wish to use things like TOP etc.
However, all the distributable packages only include CAB files for CE 4.2 for the ARM Processor, or CE 5.0 for the x86. Is there a CAB package available for CE 4.2 for the x86 CPU? (please...)
Even just the relevant .DLL files would be fine as we repackage them ourselves anyway.
Thanks.

In my homegrown data layer, I added the ability to do Order By Clauses.
I do one query with an Order By clause (all 6 records in the table retrieved).
Then I do a 2nd query without an Order By (36 of around 200 records in the table retrieved)
And I'm getting Native Exceptions.
ExceptionCode: 0xc00000000c (Null Pointer I believe)
ExceptionAddresss: 0x00c3703c (looks to be in sqlcese30.dll)
Reading: 0x00000005
I ran thru with the debugger, and am finding the error happening inside of a SQLDataReader.Read() call. It's trying to read the 14th of the 36 records that the query has found.
I am all but positive I'm not closing this database connection. The problem is happening while I'm looping off the reader data I just retrieved and in this query there was no ORDER BY clause.
I'm at a loss as to what to do about this. I'm not explicitly closing any database connections, and I'm getting the data right after performing the query.
Greetings,
I wrote a very simple C# console application which was designed to give us a rough idea on the performance and reliability of SQLCE (the source code without metrics has been posted to this group recently). What I've found is that there are major performance and reliability issues with SQLCE 3.0 as opposed to SQLCE 2.0. Whereas SQLCE 2.0 seems to be fairly consistent in terms of it's memory usage and the amount of time taken to insert rows into the table regardless of the size of the table (to a limit, after about 300,000 records it too has major performance issues), SQLCE 3.0 seems to slow down noticably and continually use more memory even after a few thousand records are inserted and actually crashes (consistently) after 25592 records are inserted!
What gives? Based on this it would seem that SQLCE 2.0 is far preferable for an unattended device that needs an uptime of over 30 days whilst constantly (several times per minute) inserting into the database.
Thanks for your thoughts on this...
I'm using SQL'05, VS'08 SQLCE 3.5 building VB.NET applications.
I'm using LocalDataCache to sync SQLCE and SQL'05
When I write a new record to SQLCE the corresoponding record in SQL'05 shows both LastEditDate and CreationDate values.
When I update the recored in SQLCE the LastEditDate gets updated, but CreationDate gets set to NULL.
Ideas?

Hi,
Does anybody know how to upgrade a SqlCE db(.sdf) file from Version 3.1 to 3.5?
And a URL where can I get related Info.
Last month , I have made a utility named sqlce viewer to help me manage sqlce 3.5 beta version databases .
The location is https://sourceforge.net/projects/sqlceviewer/
And now , I encounter a strange problem , need some help .
After user install this utility or run it standalone execute file .There has a error message poped before see the login in form . Even user has installed .net framework version 3.5 .
And if user has installed visual studio 2008 beta2 ,this problem will not existed .
This utility depend on these components :
1)WPF
2).net framework 3.5 beta
I don't know what's the reason clearly .
Anyone could give some advice are warm welcome.
can anyone tell me how to open/create a SQL Server 2005 Compact Edition database using SQL Server Management Studio Express?
cheers
I'm still having trouble deploying my Compact Edition application. The installation on other computers works, but if the program tries to start, i get the error message (translated from german):
"This Version of SQL Server 2005 Mobile Edition is not licencensed for productive use"
I always thought that there are no licence restriction with SQL Compact Edition.
Strangely the the programm works on some computers... as I think on all computers where Visual Studio is installed.
does that makes any sense to one of you?
thanks for any help,
Stefan
Hi guys,
Since the project that i'm developing is rapidly increasing, the pages seems to be getting slower everytime you view it. I would like to ask if code below would be efficient enough for several simultaneous request of data or if you have any other suggestions, you are welcome to add:

Hi All: I'm having problems creating a data connection between a windows 2000 server running .net 2.0 and a sql2005 server (server2003). I'm trying to create a connection in VWD2005 express, and when I use the visual wizard, I get a connection error with something about "named pipes" when I'm trying to connect using an alias on the server that uses tcp/ip (the alias is created in cliconfg).
If I click on "advanced properties" in the connection, and I select "TCP/IP" for the Network Library, what's displayed is "TCP/IP (DBMSGNET)" ...but shouldn't it say "DMBSSOCN"?
I'm wondering if this is correct, or a cosmetic bug in the .net sqlclient GUI, or indicative of any underlying problem that's preventing me from creating the connection?
If I manually override the connection string in web.config by entering "Network Library: DBMSSOCN", I still can't connect, getting a timeout error that the sql2005 server is not responding. But I know the server is working properly, with other .NET DB connections working within the same application...so I'm thinking this must be a problem with VWD and/or the .net framework on my local computer (not the server)?
I don't know where to begin to look to debug this problem?
Hi.
Somewhere around I find a message, which affirmed that for perfonmance it is better to use OleDb for SQL 6.5. Is this true?.
Then el SqlClient, only have perfomance in SQL 2000?
I am porting a VB.NET application using Access as its backend to use SQL Express as its new backend.
The application uses .NET 2.0 OleDbProvider to connect to the database.
The porting of the database itself to Sql Express is nearly complete, now I need to modify the application.
So, does it really make sense to modify it to use Native Sql Client instead of OleDb in terms of effort & benefits???
Moreover, if I continue using OleDb, would I need to make such small changes to embedded Sql statements like using single quotes around strings or dates instead of double quotes or pound symbols that are currently being used for String or date data respectively???
Problem encountered:
Error Code: -2147467259
Message: A call to SQL Server Reconciler failed. [,,,,,]
Minor Err. 29006
Source: Microsoft SQL Server 2000 Windows CE Edition
Any idea what could be the possible problem?
I have been trying to search thru the internet for a resolution but most of the guides are very brief about the configuration of the merge replication in mssql2000 server.
e.g. http://msdn.microsoft.com/msdnmag/issues/03/09/DataPoints/default.aspx
This link above its recommended by Microsoft, but still doesn't really helps.
Does anybody have a step-by-step guide on configuring the merge replication in mssql? With diagrams preferred.
-OR-
Is there anything wrong with these codes:
oRpl.Publisher = "HANBIN"; // HANBIN is my database server name
oRpl.PublisherLogin = "LHP";
oRpl.PublisherPassword = "<password>";
oRpl.InternetUrl = "http://hanbin/ssce/sscesa20.dll";
oRpl.InternetLogin = "IUSR_HANBIN";
oRpl.InternetPassword = ""; // do i need to put sth here?
oRpl.Subscriber = "CESubscriberTest"; // Any names will do?
oRpl.Publication = "testdbpub";
oRpl.PublisherDatabase = "testdb";
oRpl.Distributor = "HANBIN";
oRpl.DistributorLogin = "sa";
oRpl.DistributorPassword = "<password>";
Any help from any genious will greatly be appreciated.

I’m using SQLCE and SQL Server2000 to replicate to a Pocket PC running PPC MS windows 2002. What I want to know is it possible to update my cab file on the PDA remotely?
Is it possible to install the cab file trough SQLCE?
MSDN has examples of deploying SQLCE privately for C# and VB.NET, but that doesn't seem to translate to C++. A .NET application just loads the assembly it needs from the local directory, but from what I can tell I need to use the OLE DB driver to use SQL CE in C++. The problem is that the OLE DB driver is a COM object that (presumably) needs to be registered.
Has anyone successfully used SQLCE from C++ without registering any COM objects? I'm thinking the only way to do that would be to call DllGetObject() on the DLL and get the object manually, but I've never done this so I'd hate to waste the time if there's an easier way, or if this won't work.
In the readme of v3.5, it mentions that if I use 3.5 to open a database file created by previous version, the version number will be updated to 3.5, so I opened it in c# and run some select statement, then I run the verify() command and here's what's returned:
Source : d:Dataceguardian.sdf
Destination : n/a
Verifying - verMajor: 3, verMinor: 0, verBuild: 5300, verPoint: 0
Time - 2007-21-05 14:42:39.847
it seems the database file did not get updated to v3.5. Unless it's returning original info.
Then, I take this same database file and try to access from another project with v3.5 runtime + Enterprise Library, and it generates this error:
An exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in guardian.exe but was not handled in user code
Additional information: You are trying to access an older version of a SQL Server Compact Edition database. If this is a SQL Server CE 1.0 or 2.0 database, run upgrade.exe. If this is a SQL Server Compact Edition 3.0 or later database, run Compact / Repair. [ Db version = 3505053,Requested version = 3004180,File name = D:Dataceguardian.sdf ]
I am confused. Shouldn't 3.5 opens it up regardless of what version it is?
