Sysem.Data.SqlServerCe.SyncStatus' Is Inaccessible Due To Its Protection Level
Jul 28, 2006
I made a merge replication and sucessfully connected with mobile device. Everything works fine. Because I wanna try asynchronous synchronization (which won't stop my application executing when subscribing) I read How to example from MSDN :
http://msdn2.microsoft.com/en-us/library/ms172391.aspx
But there is a problem with creating SyncStatus class object. I can't get into it and I can't create. maybe some reference will help? (I use reference to SQLServerCE). This error stoped my work for now, so I am waiting for some answers.
And if it's simple resolution for this problem - sorry. I just started programming applications for Mobile Devices.
Best regards. Maciek Wysocki

I'm having problems with ftp tasks in SSIS packages where protectionlevel=EncryptSensativeWithPassword. I've used this many times with no problems, but now that I've upgraded to 2005 SP2, It's not working as before.
I have a functioning SSIS package with an FTP download. It works fine on my workstation in the developement environment.
If I load it to the SQL server using Server Manager Studio under my account, I cannot run the package from the server when logged on as Administrator, nor can I schedule it to run under the SQLAgent account as a job. The error mesages are: Unable to connect to FTP server using "FTP Connection Manager" and "The password was not allowed". Obviously the password being sent to the ftp server is wrong, but it was right under developement. Further more, If I log into the server under my account the package runs fine!
If I load the package while logged in as administrator, I can only run the package as administrator. And of course, if I load the package as SQLagent, I can only run the package as SQLagent.
This is not how SSIS packages were operating before I upgraded! In fact I've reloaded some existing packages and found that they now have inherited this behavior (after they have been re-imported)
It looks to me like SSIS is using the EncryptSensativeWithUserKey option, instead of the EncryptSensativeWithPassword option. I'm not sure how to confirm this, short of using a packet sniffer to watch the ftp traffic.
I could switch to PackageConfigurations, but I was happy with the EncryptSensativeWithPassword option, which seemed appropriate for our operation.
Does anyone have any ideas what could be going on, or any suggestions to troubleshoot this? How can I tell if password is encrypted or not?

Hello everyone,
Can someone recommend me the most efficient protection level for SSIS
packages for my environment? I've been doing some reading on this lately, but can't really decide which one to use. The Rely on server storage for encryption (ServerStorage) seems interesting, but I'm unsure if that would work on my environment (Windows Authentication).
Currently I'm saving my packages to my dev server under "Encrypt sensitive data with user key" Protection level, but seems like the passwords for the FTP Connection for instance doesn't get saved when I deploy my package to the server.
Our environment consists of 2 dev servers + 2 prod servers with windows authentication, our SQL Agent Account is a domain account with local admin rights and sysadmin rights on the SQL Server and we try to use proxy accounts to access network resources instead of giving the agent access to everything.
This is what I found on MS's web site.

Hello,
I have a package that contains a connection manager to a DB2 source. The password is configured within the connection mananger. The configuration string was included in the package configurations (SQL Server). The package is saved in VSS, and locally on my hard drive.
When a colleague attempts to open the package is Visual Studio (from VSS), He gets a message similar to the following.
Error 1 Error loading 'Geac_RK502.dtsx' : Failed to remove package protection with error 0x8009000B "Key not valid for use in specified state.". This occurs in the CPackage::LoadFromXML method. . C:Documents and SettingscdunnMy DocumentsVisual Studio 2005ProjectsGeac_RK502Geac_RK502Geac_RK502.dtsx 1 1
I'm very sure the package protection level was to encrypt sensitive data with user key. After he ran into this problem, I tried again to open the package from my computer (the machine that the package was created on) and now I get the same message. If I attempt to open the package anyway, I first get a message that there were errors in the package while it was being loaded, and that the package might be corrupt. After that message, I get one that states the document contains one or more extremely long lines of text....do you still want to open the file. If I click yes, the package opens read only with the following message:
Microsoft Visual Studio is unable to load this document. Failed to remove package protection with error 0x80090008. "Key not valid for use in specified state". This occurs iin the CPackage:LoadFromXML method.
I'm looking into more information about package protection. What can I do to avoid this problem, and what protection level should I be using so that my colleague can open the package? How can I correct the problem with this particular package, and have the package open?
Thank you for your help!

Hi all,
I have a problem while trying to deploy my packages that are configured in ProtectionLevel=EncryptSensitiveWithUserPassword
I use the Deployment Utility to deploy my packages. I set the password when deploying and the deplyment works fine. But I run the packages I have the following error : " Failed to decrypt an encrypted XML node because the password was not specified or not correct."
Did I miss something ?

For those of you who have had a hard time like me trying to figure out using Protection level for an SSIS package whilst deploying the package via the SQL Server Agent, here is a piece of advice:
Firstly the protection level is set by Default to - "EncryptSensitivewithUserKey".
The encryption actually takes place only if you have things like - passwords etc..
From my experience - using both - "EncryptSensitivewithUserKey" and "EncryptSensitivewithPassword" Security features have turned out to be unreliable when deploying through SQL Server Agent (even while using a Proxy account having all previliges).
This is it seems because of issues with the user who created the package being different from the user who deployed the package. (which is really ridiculous).
So I used the ProtectionLevel - "DontSaveSensitive" - which means it is not going to encrypt anything in the package and so ur sensitive information would be blank. You would have to then supply your password etc using a configuration XML file. - using SSIS "Package configuation" in your menu....
This has been the most reliable way of solving the whole problem with encryption.
bear in mind that you might want to put the XML file in a secure location to which no one else has access to.
Thanks

I am currently designing a SSIS package that will migrate data from Syabse to Sql server. If these packages are to be deployed to file system (as this is one time run for migrating data) or to SSIS catalog or to Sql server.
Also, I have not changed the default protection level value in packages during design time and would like to know if I have to change it while handling the deployment using DTutil (yes, i need to deploy & execute using command line utilities).
Please note that I do not have access to PROD, UAT environments and deployment team will use my BAT file that is expected to deploy and execute the packages.

Hi,
Can anyone explain to me why my ssis packages will not work when DontSaveSensitive protection level is selected? My package configurations are set as SQL server configuration type, and I have a table in a database that contains all the sensitive information (passwords and such). If I select "EncryptSensitiveWithUserKey" everything works, but I will be the only one able to execute the packages (not good, I need others to be able to execute them as well).
The error I'm getting tells me that the connection is not configured correctly or I may not have the right permissions on the connection.
My guess is that the DontSaveSensitive drops the passwords, but when I edit the data source and re-enter the password, it still does not work. Also, the database table I use that contains the sensitive data is not affected, all data remains.
What the fudge is going on here? I'm a newbie at this, can someone help me out?

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

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

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

System.Resources.ResourceReader.LoadObjectV2() at
System.Resources.ResourceReader.LoadObject() 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 ...

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.

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,

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!

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.

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?

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?

Hi,
we just migrated to SqlServerMobile 3.5. My first experience is that Version 3.5 is much slower than 3.1.
I upgraded and compacted an existing Database. Is it recommended to create a new database, instead?
Has anybody else the feeling that Version 3.5 is slower?
Are there any settings to speed up the database.
Many thanks,

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
System.Data.SqlServerCe.dll!System.Data.SqlServerCe.SqlCeCommand.CreateParameterAccessor(System.Data.SqlServerCe.MetaData[] metadata = {System.Data.SqlServerCe.MetaData[34]}) + 0x89 bytes
System.Data.SqlServerCe.dll!System.Data.SqlServerCe.SqlCeCommand.CreateDataBindings() + 0x5e bytes
System.Data.SqlServerCe.dll!System.Data.SqlServerCe.SqlCeCommand.CompileQueryPlan() + 0x16f bytes

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,
Lasker

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.

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.

Has anyone seen this error related to SSIS? I get this everytime I try to perform any action on (import, export, or run) a file system package. I am racking my brain and I would prefer not to perform a full reinstall, but I am not seeing any posts that have helped with this error.
Unable to cast object of type 'Microsoft.SqlServer.Dts.ObjectExplorerUI.ImportPackageAsAction' to type 'Microsoft.SqlServer.Dts.ObjectExplorerUI.ISimpleAction'. (Microsoft.SqlServer.DtsObjectExplorerUI)

Something strange just happened to my database.Windows Vista UltimateSQL Server 2005 SP2IIS 7.0I just did an insert into a few tables from my ASP.NET application that I'm building and I suddenly cannot query the database tables. The query window just spins and finally times out.So I decided to try a SELECT TOP and tried 100, nothing, then 10, nothing, then 1 and it returned the first row. Then I tried 2 and got that, and I remember this table had 8 rows prior to my last Insert, and once I tried to select TOP 9, it times out again.Does anyone knows why this happened and how to fix it? It's like every row past 8 either doesn't exist or got corrupted somehow. I can't even drop the table and rebuild it. SQL Server won't let me. If someone doesn't have a solution, I'll have to rebuild the entire database and I'd rather not have to do that.Any help would be appreciated.Thanks,Kahanu

Msg 945, Level 14, State 2, Line 1
Database 'Northwind' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details.
I keep getting that error for just trying to USE Northwind. I don't understand why this problem is occurring. It was working fine for the past few weeks. Yesterday something happened to the DB and it said something about recovery to which I accidentally clicked cancel. From then on I can't access some of the DB that I have on my computer.
I'm fairly new to the SQL Server Environment so I would appreciate any and all help that can be provided. I've google searched the details but I can't seem to get any of those to work. Thanks in advance for your reply.
