Problem In Opening SQL Server Express Database
Feb 10, 2008
Hi Guys,
I am try to create an application (WPF) that uses data from an SQL server database via a web service, all localized on my computer in a virtual folder.
The program work fine, it can retrieve the data from the database.
The problem arises when I want to open the same database with server explorer in VS2008 or with SQL server management studio.
Once I have used my application those two programs are not able any more to establish a connection with the database inviting me to close the program that is using the database. Even if I shut down my application and the full project those to program can not open it. I need to switch the computer off.
My application closes and dispose the connection as soon as the data have been retrieved.
The connection string that I am using is the following:
"Data Source=.SQLEXPRESS;AttachDbFilename=C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataDataBaseName.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
The question is why am I seeing these problems?
What I am doing wrong
Am I opening a connection in a exclusive way without realizing?
Please help me, I am getting crazy!!!
Cheers

Hi,
I am writing an application for a device (HP IPAQ 6828) having Windows Mobile 5.0 using
-MS .NET Compact Framework 2.0 SP-1
-SQL Mobile 2005.
-VS 2005 .NET
The application uses Merge Replication. The error occurs in the Synchronise() Method of the SqlCeReplication object.
"SQL Server Mobile encountered problems when opening the database."
repl.AddSubscription(AddOption.ExistingDatabase)
repl.Synchronize()
I also checked the the connection string and it seems to be fine. Both my device and server can ping each other. Moreever I can also access the Web syncronization folder(on server) from the device.Is anyone having a resolution for this?

Hello!
I'm trying to connect a sql ce database from a PPC with WM 2003 to a sql server 2005 database.
I discover the class SqlCeRemoteDataAccess, so i've been trying, unsucessfuly, to get things working.
I googled a lot, i read Ms Articles from MSDN, i read some posts here, but can't find solution for my problem. As you can see in my code, i already tryed different aprroaches, differente connections strings, with "provider", without "provider", with "sspi", without "sspi", you name it...
I configure the sql server agent like i read in msdn, and he's working well, i'm able to see the message. ("Microsoft SQL Server Compact Edition Server Agent" when i open the url).
The sql database credentials are correct, i already check that.
I did everything i knew and i read, unfortunately i still can't manage to find a solution for an error message:
"SQL Server Mobile encountered problems when opening the database." The native error is 28559
That's an Exception error message, that appears to me.
Can somebody help me?
Thank you!

hello,
I have a question about opening files in the Microsoft SQL Server 2005 Management Studio.
In the old Query Analyzer from SQL 2000 I can open SQL Files via drag & drop (from explorer to QA) or open it with a double click in the explorer. Then the Files opened, if I had actual a connection to a server / database (QA is stared with one file and has a connection to Server/Datebase), with this connection.
Now in Microsoft SQL Server 2005 Management Studio I'll be asked everytime for Server and have to get the database from the database list - it does not connect automaticly to server/database, that is actual connected (I have opened a file with the connection and a connected database in the object explorer).
Someone do not have this problem - but we found no option to set it up.
Any ideas?
thanks &
best regards,
Christian Kiedels

I'll try and ask one more time. Does anyone have a clue how to fix this?
"A SQL Server Compact Edition DLL could not be loaded. Reinstall SQL Server Compact Edition. [ DLL Name = sqlceca30.dll ]"
or
"SQL Server Compact Edition encountered problems when opening the database"
"Internal error: The database is not initialized."
I've been fighting this for well over a week now. My XP based version works fine but this error occurs routinely on my CE4.2 device. I cannot find anything meaningful using Google other than 'look for non disposed' replication objects which I've done. Is this bad hardware? I don't believe I'm out of memory as the app is about 1.2MB including about 8 DLL's and GC indicates I have about 300KB of objects at the time of the failure. I also use a bunch of static (global) objects that I use throughout the code.
It would be nice if I could get the lower level error messages causing these failures but that is probably too much to ask.
The odd thing is that it's only the replication engine that fails as even after the failure, the app can reopen the DB and work with the data just fine.
My basic order of the application is...
1 Open DB SqlCEConnection
2 Create/Prepare any SqlCECommand objects
3 Do work here
4 Dispose any SqlCECommand objects
5 Close DB
6 Dispose SqlCEConnection object
7 Create SqlCEReplication object
8 BeginSynchronize
9 ... error here..
10 Dispose SqlCEReplication object
11 Reopen DB SqlCEConnection
I've tried creating the Replication object at program start and that does not help. I'm guessing there is something about .net that I don't understand either with stack space, # dll's or whatever. I've rearranged the order of the Dispose, Create, SQL CE objects to include just about every permutation but still am hitting this same problem.
Are there any tools that can help me profile this app for memory problems or usage? Everything seems geared for .Net and not .NetCF.
thanks.

Hi everybody,
I am using VB Webforms as my front end and MSDE 2000 as my back end. I am not able to drop a database after executing the following vb code on that database:
Dim vConnection As New SqlConnection(vConnectionString) Dim vAdapter As New SqlDataAdapter("SELECT party_type_code, party_type_name, party_type_imported" & _ " FROM Party_Type" & _ " ORDER BY party_type_name", vConnection) Dim vDataTable As New DataTable() vAdapter.Fill(vDataTable) vAdapter.Dispose() vConnection.Dispose()
On trying to drop the database using the SQL Command "DROP DATABASE PPCABCD2005", I get the error message:Cannot drop the database 'PPCABCD2005' because it is currently in use ...However, if I don't execute the above code, I am able to drop it. Why is it so? What is the solution to this problem?

Hello, Im new with databases.
I know that opening a connection to a DB is expensive. Usually I write a method that opens a connection to the DB then I execute a query and then close the connection. Pretty standard.
OK, so how do I handle opening connections to the database when I need to run multiple queries. For example, i have a webpage that need to query the database to see if the user has moderator privledges, then depending on that query I have to query the DB again for moderator specific information or non-modertaor information.
So in this case how do i handle opening connections to the DB. Is it ok to generally have to open a connection to a DB multiple times on a page load?
The obvious solution is to keep the connection open. That is, open a connection, query the Db, keep the connection open, do the conditional statment ( if is_Moderator) then query the DB again for the info that I need, and then close the connection. But, from all the books that Ive been reading this is not a good practice because business logic should not been in the dataAccess layer.
Any help would be much appreciated.

Howdy folks!
If I set the following three properties when creating a database, do I need to set the same properties when I open the same database later?
sscedbprop[0].dwPropertyID = DBPROP_SSCE_AUTO_SHRINK_THRESHOLD;
sscedbprop[0].dwOptions = DBPROPOPTIONS_REQUIRED;
sscedbprop[0].vValue.vt = VT_I4;
sscedbprop[0].vValue.intVal = 100;
sscedbprop[1].dwPropertyID = DBPROP_SSCE_MAX_DATABASE_SIZE;
sscedbprop[1].dwOptions = DBPROPOPTIONS_REQUIRED;
sscedbprop[1].vValue.vt = VT_I4;
sscedbprop[1].vValue.intVal = 4091;
sscedbprop[2].dwPropertyID = DBPROP_SSCE_ENCRYPTDATABASE;
sscedbprop[2].dwOptions = DBPROPOPTIONS_REQUIRED;
sscedbprop[2].vValue.vt = VT_BOOL;
sscedbprop[2].vValue.boolVal = (a_bEncrypted==TRUE)?VARIANT_TRUE:VARIANT_FALSE;
Thanks!
BTW, why is the max size not 4096?

When I downloaded/started using Visual Web Developer I was under the impression that I needed to install SQL Server Management Studio Express in order to create/manage databases, and to provide the engine to access the data.
Since then I have found tutorials and have successfully created/used databases solely from within Visual Web Developer. I'm assuming that Visual Web Developer includes a database engine, much like the webserver that is included. (This is an awesome thing).
When I tried to upload my web application with database to my production server, the database would not work, it started working after I installed SQL Server Management Studio Express on the server.
Is it my understanding that you need SQL Server Management Studio Express if you do not have Visual Web Developer Express installed in order to provide the data access engine?
Also, I am unable to "attach" my Visual Web Developer Express created database to SQL Server Management Studio Express. Are there any posts that provide more information about this topic?
The only reason I'm asking is that I have extra whitespace on the end of my text fields, and I thought ANSI_PADDING was turned on. I do not see the option in Visual Web Developer Express, but have found it in SQL Server Management Studio Express.

Hi,
I am a newbie so i apologies beforehand for any mistakes i make on this forum.
Anyway, i created an asp.net website using the MS Visual Web developer tool. This has a couple of SQL SERVER databases within it.
I then latervinstalled the SQL SERVER management studio express in order to manage the SQL SERVER DBs that i had as part of my website but they do not appear within the management studio db list.
As this is the express version, is there anyway of importing the existing SQL SERVER dbs that i have to the management studio so i can manage them from there?
Regards,
Shuja.

Okay, I've read massive topics on ClickOnce, and embedded database applications, etc, etc.
I need a handful of good suggestions how I can create a deployment package, to get my sql express database onto a SQL Express server.
The database will need to be multi-user, because I am also developing a WinForms application to connect to the SQL Express database.
I'm thinking I need to use some automated scripting features, to generate scripts for the database once I am done (unless you have a better suggestion).
After that, I need to know what to do with those scripts, and how can I create a setup / deployment packages to run those scripts against a SQL Express server.
The other alterntative obviously is to copy my sql express database, and run an attach command. This will work the first time, only because this will have been the first deployment of this database.
Please keep in mind when answering this question, that I will not be embedding the database, and as far as I understand ClickOnce is a feature for use with embedded databases or user instance databases (not sure).

Hi, I'm completely new to SQL Server and ASP.NET, so please bear with me on my learning curve! I've installed Visual Web Developer Express and SQL Server Express (on the same PC). I then used Web Developer Express to successfully create a new database with a couple of tables in it. So far so good. I then installed SQL Server Management Studio Express on the same PC and tried to connect to my new database. The connection to the SQL Server instance appears to work OK (using Windows Authentication) but I can't see the database I previously created. All I can see are the System Databases. Does anyone know what the solution might be?

Hi all,
In the last one and half years, I used the Northwind Database in SQL Server Management Studio Express (SSMSE) to learn the programming of SqlConnections, Data sources, Database Exploere, ADO.NET 2.0, etc. via VB 2005 Express.
The Northwind Database in my SSMSE got lost very often, but I was not aware of it. How can I know where the Northwind Database is used or processed by my VB 2005 Express projects that were the examples of some tutorial books or my trial projects? How can I release the Northwind Database back to my SSMSE from the VB 2005 Express projects? Please help and advise.
Thanks in advance,
Scott Chang

sql mobile encountered problems when opening the database
It happens when I sync data.
However, when I sync data users and customer info, it doesn't give this message, But when I sync (third time) order info, this message comes out.
--when i run on my PPC (HP ra1950), there is no this error message.
I think it is a bug?

Hi all,
I have read/studied (i) Working with Databases in Visual Web Developer 2005 Express in http://quickstarts.asp.net/QuickStartv20/aspnet/doc/data/vwd.aspx, (ii) Xcopy Deployment (SQL Server Express) in http://msdn2.microsoft.com/en-us/library/ms165716.aspx, (iii) User Instances for Non-Administrators in http://msdn2.microsoft.com/en-us/library/ms143684.aspx, and (iv) Embedding SQL Server Server Express in Applications in http://msdn2.microsoft.com/en-us/library/ms165660.aspx. I do not understand the concepts and procedures to do Xcopy and User Instances for non-administrators completely-I do not know how to connect to databases and create database diagrams or schemas using the Database Explorer. I have a stand-alone Windows XP Pro PC. I have created a ChemDatabase with 3 dbo tables in the SQL Server Management Studio of my SQL Server Express and a website of my VWD Express application with an App_Data folder. I am not able to proceed to use Xcopy and user instance to bring the 3 dbo tables of ChemDatabase to my App_Data folder. Please help and give me some detailed procedures/instructions to bring the 3 dbo tables of ChemDatabase (or ChemDatabase itself) from the SQL Server Management Studio Express to the App_Data folder of the website of my VWD Express project?
Thanks in advance,

I have a solution with a couple of ssis projects in it. Everytime I open the solution, Visual Studio creates an extra .database file for the project's existing xxx.database file. The solution is under VSS control and VS2005 checks out the project and shows the file as a newly added file.
What causes this and how can I prevent this from occurring?
The files contain this:
<Database xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dwd="http://schemas.microsoft.com/DataWarehouse/Designer/1.0" dwd:design-time-name="d3ce9653-3ac5-4ee5-85c3-7d60b2e5f109" xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">
<ID>Publish</ID>
<Name>Publish</Name>
<CreatedTimestamp>0001-01-01T00:00:00Z</CreatedTimestamp>
<LastSchemaUpdate>0001-01-01T00:00:00Z</LastSchemaUpdate>
<LastProcessed>0001-01-01T00:00:00Z</LastProcessed>
<State>Unprocessed</State>
<LastUpdate>0001-01-01T00:00:00Z</LastUpdate>
<DataSourceImpersonationInfo>
<ImpersonationMode>Default</ImpersonationMode>
<ImpersonationInfoSecurity>Unchanged</ImpersonationInfoSecurity>
</DataSourceImpersonationInfo>
</Database>
There are 2 of us working on the solution and the other fellow does not see this behavior.
The files do not show up in the VS2005 solution explorer. If they are user specific as I suspect (impersonation info?), then they should not be added to the .dtproj project file.
Thanks!

I have created an .sdf database on my Desktop - and am able to open and close it just fine from my application program.
Whenever I try to:
Open it with the same program but installed on a different PC,
or:
Open it from a program running as a service on the development PC, I get the error
"The operating system does not support the Encryption Mode provided."
The working above is from the Version 3.5 Beta, but the same problem occurs with Version 3.1.
The Error code in Hex is 80004005
I can't find any reference to fixing this error - any ideas?

Hi,
I'm trying to learn some VB programming with the VB 2005 Express Absolute Beginner Series video tutorials (which I think is great) and have come across a problem that I can't solve.
When I follow the instructions in Lesson 9 (Databinding Data to User Interface Controls) my application will display the data from the database correctly and I can edit it (and as long as the debugger is running the data remains changed). However, the changes won't propagate back to the database. I don't get any error messages but after I edit the data, save (with the save button on the BindingNavigator toolbar), and end debugging the data in my database remains unchanged. When I use a MessageBox to show how many rows where edited/updated in the
Me.myTableTableAdapter.Update(Me.myDatabaseDataSet.myTable)
I get the correct number back. I'm sure the problem is not due to coding errors since I've also tried running the accompanying Lesson 9 project file that can be downloaded from MSDN and the problem persists.
I'm using Windows XP SP2, SQL Server 2005 Express Edition and VB 2005 Express Edition. I've tried installing SQL Server 2005 Express with a number of different settings, including default settings, but it doesn't make any difference.
Would greatly appreciate any feedback on this as I'm keen to resolve this problem so I can get on with the next tutorial lesson.
Thanks,
Ieyasu

Hi, i have a MDF file used by an asp.net application (with sql server 2005 express).
I want to make it to a permanent database in sql server express.
I know that i can attach it from Management Studio, but is there no better way?
Does it exist a way to 'import' or 'migrate' or copy' a .MDF.database into the central sql server, as if created directly in sql server express? After that, i can delete the .MDF file.
Thanks
