I am trying to implement a web service that creates and populates a SQL Mobile database file, then returns the created database to a mobile device as a byte array. The database size could be in excess of 500,000 rows, which is why I want to do as much of this preprocessing on the server before it gets to the mobile device. I can't use replication since I have to do some shaping of the data before I can use it on the mobile device.
Unfortunately, the web service is throwing the following exception when I try to instantiate a SqlCeConnection object:
"System.NotSupportedException: SQL Server Everywhere Edition is not intended for ASP.NET development."
Are there any suggestions as to how I can get around this potential limitation? If I refactor out the code that actually performs the SqlCe operations to a separate assembly, but still call that assembly from within the ASP.NET process, will I get the same error?
I know that you can work with Sql Mobile databases from the deskop, and I suppose I could invoke a console application to create the database, but that seems like such a hack.
What is exactly the recommended way of using a SqlCeConnection object in your application?
In all the examples I see (IBuySpyDelivery for example) it opens the connection object in the constructor and leaves it open most of the time until the class gets disposed.
Is that the way to do it? Or should you open and close the connection for each database action (insert/select/delete) you're doing on the local SQL Mobile database?
I'm a bit confused, but maybe I'm messing up the way of working on remote database servers with how it should be done on a local SQL Mobile db.
I'm having a problem where I am getting a "Permission denied" exception when I call Open on a SqlCeConnection object using SqlCE version 3.5. It does this when mode is set to Read Only in the connection string. Furthermore it does this on XP, but not Vista. Here is the connection string I'm building:
I know that with traditional SQL systems, it is important to only open connections to a sql server when they are needed. However, since there is no "server" in mobile apps, is it bad practice to leave one open throughout the duration of an application?
The application is going to be constantly reading and writing to the data tables and it seems like it might be a good idea to leave it open.
I am writing an application using VB.Net 2005 for the Windows CE 5.0 device and it is connecting to a SQL Server 2005 Mobile Edition Database. The trouble I'm having is establishing a connection to a SQL Server Mobile database on the device.
Here is the code I am using:
Code Snippet Public gConnectionString As String = "Data Source=Program FilesMobAppMobDB.sdf;Persist Security Info=False;"
Code Snippet
Imports System.Data.SqlServerCe
Public Class DBManager
Public Shared gSQLCEConnection As SqlCeConnection
Public Shared Function OpenDB() As Boolean
If gSQLCEConnection IsNot Nothing Then
Throw New InvalidOperationException("Connection already open.") End If gSQLCEConnection = New SqlCeConnection(gConnectionString) Try
gSQLCEConnection.Open() 'Error occurs here Return True Catch ex As SqlCeException
MsgBox(ex.Message & vbCrLf & ex.HResult & vbCrLf & ex.NativeError & vbCrLf & ex.Source) Return False End Try End Function
In the immediate window I recieve the following messages:
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll

A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
A first chance exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in System.Data.SqlServerCe.dll
I believe that the first few lines are caused by the icons/pictures that I have included with my app, but the SqlCeException line occurs when the connection to the .SDF file is trying to be established.
Here is the exception output:
Message: "" (Blank) HResult: -2147024882 NativeError: 0 Source: SQL Server 2005 Mobile Edition ADO.NET Data Provider
Programs under Remove Programs on the PDA are: Microsoft .NET CF 2.0 ENU-String R... Microsoft .NET Compact Framework...

Microsoft SQLCE 2.0 Microsoft SQLCE 2.0 Dev
Any ideas on what could be stopping this connection from being established? It was working before but all of a sudden just stopped. I have warm booted, cold booted, and rebuilt with no luck and also checked that SQL Query Analyzer is not running on the PDA and that the connection string is valid. The call to OpenDB occurs in the form_load of the startup object.
I've a slight problem with configuring my Report Server. I have set up everything apart from the initialisation and and the Windows Service Identity, however when I select the panel for the latter I am presented with a message box displaying the following:
" Reporting Services Configuration Manager:
There was an error while switching panels. The most likely cause is an error retreiving WMI properties. The exception details are:
InvalidArgument=Value of '1' is not valid for 'SelectedIndex'.
Parameter name: SelectedIndex "
I have tried re-installing the entire SQL server setup and this made no difference, I followed this by removing then reinstalling just the Report Service. Still nothing.
Any ideas as to what it is doing and how I should go about fixing it?
Hi, there; I have a couple of issue that really frustrates me. I asked a similar question before but I haven't resolved it yet. My application was developed with VS2003, c#,CF1.0,Sp1.
I found that after my application runs for a couple of hours, my SqlCeDataAdapter.Fill() method throw exception "Error Code: 8007000E Message : Not enough storage is available to complete this operation.". I found a couple of threads on the website said that I have to dispose adapter object (including its command objects.) Yes, I did!!!. And I also dispose my SqlCeConnection before it is out of range and recreate it when I need it. See:http://www.tutorials-se.com/sqlserverce/Keeping-SqlCeConnection/
I also introduced hotfix from http://support.microsoft.com/Default.aspx?kbid=827837. It looks like I tried everything, but I still has this exception.
At the same time, From thread "http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=426640&SiteID=1", Mr. Ilya said "native DLL (e.g. bar code scanner API) " could cause AV (access violation) issue. Yes, my application is running on Symbol 9062B device which use barcode scanner API, sometimes application will have "0xc0000005" exception when it exists (not when it is running) A serious problem is that the laser randomly crash in the middle of the scanning without any exception. I am quite sure it is not code logic issue. This happens since I introduced two SqlCeConnections which point to two different .sdf files (run at background threads). My impression is that the memory or stack are corrupted for some reason.
Hopefully I make myself clear. So my question is: 1. Will Sp3 help this? (Of course I will do some test) 2. How can I know memory or stack are corrupted/How to trace.
Again, thanks Mr.Ilya, you do a great job here, you are really really helpful!
I've got an application uses a WPF GUI, is built in VS2008 final, targets .Net Framework 3.5, and uses a Sql Ce 3.5 database for local storage. After a specific WPF window is rebound the application hangs. Hitting pause on the debugger reveals the offending method is a call to SqlCeConnection.Dispose(). Via Reflector I can see this method calls SqlCeConnection+ObjectLifeTimeTracker.Close() which in turn calls GC.WaitForPendingFinalizers(). Within WPF there are some objects (specifically TextBox) which need to have their resources freed on the main application thread. The finalizer thread is waiting on the main application thread, which is in turn waiting on the finalizer thread, resulting in a deadlock.
You can see some additional discussion of the topic including our temporary resolution in this thread.
My question is why is there a call to GC.WaitForPendingFinalizers() buried within the SqlCeConnection.Dispose() call tree?
public void Dispose() { if (this.connection != null) { this.connection.Dispose(); } } // ... }
This only happens when I'm calling Application.Exit(); and Dispose is called through the destructor of the DatabaseManager class. When I'm disposing the connection during normal work the call works as intended. BTW I'm using SQL Server Mobile 3.0.5214.0 on a PPC 2003 AKU2 (Symbol PPT8846 industrial device).
I am facing a problem with vb.net application which i created to connect with and sqlservermobile edition file (.sdf). while the connection is declared, its producing the error that "Exception from Hresult : 0x4007000B." and some inner exception error lines. i imported system.data.sqlceserver and added the references too.
but It is working in my one of the system. i tried the same in some other system,its not working. you frndz have any about this. I think the system is lacking some dll files. any body having an idea about this. pls help me out.

I am getting the error: Cannot open database "aspnetdb" requested by the login. The login failed. When I browse to my ASP.NET 3.5 LINQ web application on the IIS 6.0 server on Server 2003. I imagine this is because while I granted SQL Server 2005 login and permissions to my database that the application stores its data in, I did NOT grant any rights to the service account the IIS Application Pool uses for its identity to the aspnetdb database on SQL Server which is where all my roles information is stored at. My question is what are the MINIMUM permissions needed for this database so it can perform its roles related functions? I'm using Windows Authentications with the SQL Role provider for authorization.
Thank you.
EDIT: I think I only need to open the aspnetdb database and add my login to the aspnet_Roles_FullAccess role. Is that correct?
I get the below error only when my IDE open. It connects well when it is found closed. [SqlException (0x80131904): Cannot open user default database. Login failed.Login failed for user 'JPASPNET'.] I could solve this by giving the logged in windows user to impersonate under IIS window > WEBSITE > ASP.NET tab > EDIT CONFIG > APPLICATION tab But I wish someone could give me the proper solution. I almost tried all from giving ASPNET user as a administrator to configuring the same in Express management tool. Environment: XP pro, VWD and SQL Express
I got an approach like that: 1) Read something from DB - check the value, if true stop if false go on2) Read the second Value (another SQL Statement) - check the value etc. Now I could open the connection at 1) and if I have to go to 2) I leave the connection open and use the same connection at 2). Is it ok to do that? The other scenario would be opening a connection at 1), immediately close it after I read the value and open a new connection at 2). Thanks for the input!
Post installation of SQL Server 2014 Express edition, I am able to connect to the Database Instance.
But while opening a new query window in SSMS or opening a table getting the error:
Package 'RadLangSvc.Package, RadLangSvc, Version 12.0.0.0, Culture=Neutral, Public Token=89845dcd8080cc91' failed to load

I have an almost virgin install of SQLExpres running on a WIN2K Pro system.
Have been able to create and connect db to Access 2000 without problem.
Now I wish to extend to remote connections. Using Surface Area Configuration tool, I changed Remote Connections to Local and Remote.
Whenever this setting contains TCP/IP and I try to restart the service I receive the following errors:
System Log:
The SQL Server (SQLEXPRESS) service terminated with service-specific error 10013.
Application Log:
Server TCP provider failed to listen on [ 'any' <ipv4> 0]. Tcp port is already in use.
TDSSNIClient initialization failed with error 0x271d, status code 0xa.
TDSSNIClient initialization failed with error 0x271d, status code 0x1.
Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log.
SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.
If I change back to Local Connections Only or Local and Remote using named pipes only, the service starts up again without a problem.
After five days of investigating, researching, reinstalling and waiting I have to ask for help.

Hello! I have the following problem. I developed CLR Stored Procedure "StartNotification" and deploy it on db. This sp calls external web service. Furthermore, this sp is called according with SQL Server Agent Job's schedule. On my PC SQL Server works under Local System account and this web service is called correctly (Executed as user: NT AUTHORITYSYSTEM). But on ther other server the following exception is raised during job running: Date 17.04.2007 16:42:10 Log Job History (FailureNotificationJob)
Step ID 1 Server MSK-CDBPO-01 Job Name FailureNotificationJob Step Name MainStep Duration 00:00:00 Sql Severity 16 Sql Message ID 6522 Operator Emailed Operator Net sent Operator Paged Retries Attempted 0
Message Executed as user: CORPmssqlserver. A .NET Framework error occurred during execution of user defined routine or aggregate 'StartNotification': System.Security.SecurityException: Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. System.Security.SecurityException: at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Net.

What is the reason of this behaviour? Unfortunately I do not have direct access to this server. I have the following guesses: 1) CORPmssqlserver may have not enough permissions to call web service 2) Something wrong with SQL Server account's permissions 2) Something wrong with SQL Server Agent account's permissions I will take the will for the deed. Thanks.
We are using the whole BI-package from Microsoft - from SQL, DTS-package,Raporting Service and Analyze Service.
It should be very helpful to be able to create a metadata databases where you could find all releations between different objects (tables,views,reports,cubes,DTS-package,Databases.
Just to get answer for: 'where is view xxx used', 'what are Report xxx depending upon'.
While everything exists in different SQL databases it should possible to do.
I have a initiator and a target service broker peer.
Both are controlled by a C# unit test. The initiator uses the Microsoft.Samples.SqlServer class. The target service uses stored procedure activation.
Sending a message from the initiator to the target, saves the content of the message, along with its conversation handle in the target's database specific table.
The unit test needs - at a later time - to instruct the target to send a message back on the same conversation handle to the initiator service.
For this the C# unit test creates a Conversation off of the saved conversation handle:
Service client = new Service("cleintservicename", conn, tran);
Conversation dialog = null;
dialog = new Conversation(client, convHandle); Sending the message on this dialog generates an error "Message body: <Error xmlns="http://schemas.microsoft.com/SQL/ServiceBroker/Error"><Code>-8495</Code><Description>The conversation has already been acknowledged by another instance of this service.</Description></Error>". Is the error due to the fact that a service - using the activated stored procedure already picked up the conversation, so that a new reference to the service can not be created through the Service class in CLR? If so, I might need then to skip the activated stored procedure in favor or a CLR service, alltogether? Any help - greatly appreciated.
We seem to be being plagued by the error below by our SQL Server agent. This happens almost everytime we restart the server that has been running for a day or two.
Our SQL Server Agent uses a none expiring domain credential. I understand that this problem only happens when the profile being used by the SQL Servr Agent has changed (password change). What puzzles me is that the login is A ok and no changes has been made to it's password.
We always resolve this problem by changing the login used in the SQL Server Agent to local and after that, returning it back to it's original domain login. Unfortunately, we cant always do this everytime something goes wrong.
Can anyone please help us shed a light on this? We're using SQL2k with SP3a. Thanks!

Just a quick question about connection management. My application willnever need more than 1 or 2 connections about at any given time. Also, I donot expect many users to be connected at any given time. For efficiency, Iwould like to keep connections alive throughout the lifetime of the objectsrequiring them, rather than opening a new connection, executing code andthen closing it again. What is the most efficient way of doing this?Should I perform the open/close or just one open when I create the objectand a close when I dispose of it?

I have configured an instance to use static port, say 1435, and I turned off the Browser service.
I would like to know if I can use SSMSE to connect to the instance database directly. The instance is listening at port 1435 and accepting connection requests from other methods.
What I need to put into the "Server name: " field?
Normally, it would be like: <serverIP><InstanceID> with Browser turned on.
Now how do I add the port information to it, I tried
I am looking at implementing some sort of throttling whereby "expensive" reports are setup as Subscriptions (and hence are run by the Windows Service), while all other requests go the Web Service.
My question is:
Do the two systems share any underlying systems? I understand (of course) that they use the same DB, etc. etc. However, I can't quite tell whether there is an underlying engine that is a common base or if they really just spin up different instances of the same objects and essentially each host the application separately?
I am currently hardening our SQL 2012 (with AlwaysOn Availability Groups) environment. Both the SQL service and agent account are using service accounts (only domain user). SQL browser service is disabled. Permissions to all roles are handled by using domain groups.
Currently a lot of (default) NT Service accounts are listed (some with sysadmin privileges). Are there accounts that can be removed?
Hi all, I do understand that it is highly recomended to have aserprate user (perfered a domain user account) for each of the SQL Server service and SQL Agent service. What is the reason behind that? (Someone told me to not run the service with an account that has a powerul privilegs! - I don't undrstanmd this point can you explain it please?) What is the diffrent between: 1- Local System account 2 -Network Service account
