Hi,
I write a .NET Windows Form that connect to SQLExpress datafile. After updating data, I want to zip the .mdf file and send email. However, I got an exeption that the .mdf file is used by other thread so I cant zip. Even I try to close all connection, I still cant zip.
Is there any way to detach/unlock .mdf file connecting by SQLExpress?
MA.
Hi, I've created a simple hit counter in my Session_Start event...
Dim myDataSource As New SqlDataSourcemyDataSource.ConnectionString = ConfigurationManager.ConnectionStrings("DatabaseConnectionString1").ToStringmyDataSource.UpdateCommand = "UPDATE Stats SET Hits = Hits + 1"myDataSource.Update()
It works fine but do I need to close the connection after I've finished with it or is this ok?
Thanks for your help.
Hi all,
If this is used eg.
Return selectCommand.ExecuteReader(CommandBehaviour.Default)
Here do i need to close the connection in finally explicitly????
Are there any links which can answer this kind of question ???
Thanks for any help in advance.....

Hello all,
I have a DB on my WM2005 device.
I'm using a program which connect to the DB using a CN.
On the constructor of the DB Class I use the line
static string connString = "Data Source='" + strDB + "'; LCID=1033; Password=" + strPass + "; Encrypt = FALSE;";
SqlCeConnection cn = new SqlCeConnection(connString);
Then I Open the Connection.
Now, in some ways I need to drop a Table.
Before I do so, I disconnect the DB but I'm using only the line
cn.Close();
I saw om the Watch attributes that its not a real disconnect to the DB.
When I try to Drop the Table I get this message:
The system timed out waiting for a lock. [ Session id = 25,Thread id = -2096711882,Process id = -2090594918,Table name = Movies,Conflict type = x lock (s blocks),Resource = DDL ]
And the Table doesn't drop.
Is it related to the constructor line I made?
What is the best solution to Drop a table..and then to get connected again with the DB.
Thanks in advance..
How do you close the connection at the SQL Server? I have a backup I want to resotre to SQLExpress using SQL Management Studio Express. When I try, the SQL tells me he can't because the database is in use. I don't realy care about this I still want to restore the database. So I figured it's because there are some active connection to the database. My gues is I have to close those, but how? I also know I can restart SQLExpress and the connection will drop, but this server has more then one database, so I cant always do that. I'm looking for some T-SQL like DROP ALL CONNECTION.
Thanks for the help.
I designed a DTS package with eleven different connections. When I try to see the proberties of a connection the enterprise manager immediatly closes without giving me a warning. This happens only with two connections (in my example M1 and M2). This mistake has no influence to the execution of the package. In my opinion it is a fault of the DTS package desinger but may be that I made something wrong.
Is there anybody who knows this mistake? Thanks for your help.
I have the next code in my proyect:

If SQLConexion.State = adStateOpen Then SQLConexion.Close
SQLConexion.Close
End If
SQLConexion.Open SQLSentencia
AbreConexionSQLSERVER = 0
If I detect that the connection is opened while I am initializazing varriables, I want to close always the connection and then begins my aplicattion always opening the connection, but it always returns a error 91..
suggestions?
The following error message was displayed in the SQL server event log when the client application attempted to connect to sql server
"The Tabular Data Stream (TDS) version 0x72020002 of the client library used to open the connection is unsupported or unknown. The connection has been closed. [CLIENT: XX.XX.XX.XX]"
Can anyone tell me what this means?
Thanks
Please i have a question,
I want to use temporary tables to handle my forms child tables data.
My question is after i load the data from #temporary table to my dataset then i will close my database connection.
Does my temporary tables gets dropped off as soon as i do the connection.close.
or do i need to drop the #temporary table by code.
Which one is right.
I know #temporary tables are specific to the users(session)
Thank you very much in advance.
we have roughly 22 people connected to one database. But after a while, their applications begin to drag due to in and out communication with the server. When i check the active connections on the sql server, some times i see 157 active connections, please how to i set a timeout or connection interval close, so as reduce the heavy load being put on the server. Or how can i automatically close connections when they get higher than 50 connections.
This settings should be sql server 2008 related.
Hi,
My question is if I close the sqlreader i am using. will that close the connection it uses or the connection will still remain open?

I am using SA user to connecto the server. When I checked the server with managment tool I found out sa doesn't have permission to use this new database of mine. So I tried to add that by going into

So i get this version of sqlexpress up and running and i copy all my databases over on to it. Redo my Logins for te server and then add the the DSN to ODBC admin console.
And still no good >:_( this is the error i get:
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open database "publicSite" requested by the login. The login failed.
So i know im doing somthing really stupid.
So heres what i got:
ASP connection srting looks like this:
<%
// FileName="Connection_odbc_conn_dsn.htm"
// Type="ADO"
// DesigntimeType="ADO"
// HTTP="true"
// Catalog=""
// Schema=""
var MM_PublicSiteJS_STRING = "dsn=publicUSR;uid=publicUSR;pwd=**********"
%>
now it ther a special ODBC driver used for SQLExpress or can i use a standard SQL driver?
any help would be much apriciated.
I see this question a lot, so I thought I would go ahead and post the answer here.
Q: How many connections does SQL Server Express support?
A: Unlike MSDE, SQL Server Express does not limit connections. SQL Server Express supports:
1 gb RAM (note the machine can have more memory, but 1gb will be used by SQL Express)
1 processor (again, the machine can have more, but just 1 proc will be used by SQL Express)
4 gb database size (note, there can be multiple databases, but none of them individually can be more than 4 gb)
Hope this helps,
Thanks< MJ
0) I've build on my pc a file MDF...i've used it and it's all right.
Then I've decided to use it in LAN on pc-server to share it with my team.
1) The sqlexpress is installad on pc with XP sp2 (as server)
2) Tcp Ip is enabled.
3) Firewall is not running
4) The folder where is located the Mdf file si public without restrictions
5) The autentication is performed via Windows.
6) The service sqlbrowser is enable and running at start.

What's the problem?
I installed on a w2k/sp4 local machine SQLEXPRESS.
I copied the database also to the localmachine
With the sqlexpressmanager I attached the database. Everythinks looks fine.
I quit the manager, but then I start the manager again. Now the manager can't find the sqlserver.
Timeout Expired is the message.
Why is that? I installed SQLEDXPRESS on a lot of machines. No problems. But those machine the manager lost the connection after the first time.
thanks again.

i got an error just like that.What must i do?
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.

I am having difficulty converting my CGI(perl module) connection from mySQL to SQLexpress. Does anyone know what the connection string should look like?
Listed here is my current connection string. I'm trying to get this done this week. Please email me if you have an answer in addition to posting.
$dbh = DBI->connect("DBI:mysql:database=$var{database};host=$var{server}","$var{root_username}", "$var{root_password}",{'RaiseError' => 0, 'PrintError' => 0});
Much appreciated,

Hi all,
I followed an excellent tutorial (from Microsoft) about creating and using a SQLExpress db table internal to your website and the site I created works just fine - locally. When I publish to my web host provider I get this error:
[SqlException (0x80131904): An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)]
My web host provider supports .NET 2.0 but doesn't support MS SQL Server. But that should matter - right? Because I'm putting the db instance right in the website?
I did a search and followed some of the advice:
I went into the SQL Server Surface Area Config Mgr and set SQLExpress for local and remote connections and rebooted/republished. I also have SQL Server 2005 installed as a separate entity (if that makes a difference).
I still get the above error. This is the connection string from the web.config:
<connectionStrings>
<add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Customers.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
And this is the call from the markup:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT * FROM [Customer]"></asp:SqlDataSource>
Does any know the fix for this?
Thanking you in advance

I am running SqlExpress on a Vista machine as a server and accessing it from machines running XP. I could not connect with the Vista server until I turned off the firewall, despite creating exceptions for both the sqlexpress and sqlbrowser services in the firewall setup. Obviously, I don't want to run on a wireless network without a firewall for any length of time. What else to I need to enable in order to run with my firewall up? In SMSS, I could 'see' the Vista server on the network with the firewall up, but I could not 'see' the SERVERSQLEXPRESS service or connect to it .
thanks,
Steve
I am using Visual Studio 2005. I am creating an SQL database with a web enabled front end. I am using Microsoft SQL Server Management Studio to create the database objects and an ASP.NET web page created in Visual Studio for the front end. My problem is centered around the two server instances which come with Visual Studio (MSSQLSERVER and SQLEXPRESS). The database objects are being created on MSSQLSERVER by Microsoft SQL Server Management Studio. However, in a Visual Studio ASP.NET web page, when I create a new conection string using the menu functionality, in the SQLDATASOURCE object or in the server explorer, only (My Computer Name)SQLEXPRESS shows up as an option. I have tried typing (My Computer Name)MSSQLSERVER in but the database list just comes up blank. I know that MSSQLSERVER exists because I have one active connection string to it created by a friend. They had to juggle a lot of things to make MSSQLSERVER appear and since I was just getting started then it went over my head. Whatever they did was temporary though and I havn't been able to repeat it to add new connection strings. To eliminate some of the obvious things in other posts:
*MSSQLSERVER is Started in the Services Screen
*In the configuration manager MSSQLSERVER has shared memory enabled
*On the advice of one post or proceedure I enabled TCP/IP and restarted the service (I think this is actually for remote connections everything I am doing is on one PC)
What I really want is to have things permanently set up so MSSQLSERVER always shows up as an option when creating a connection string in Visual Studio. If this means getting rid of SQLEXPRESS I won't shed too many tears.
As you have noticed everything in this is centered around Visual Studio's menu functionality. I am currently make thee code paradigm shifts.
Form -> ASP.NET
VB6 -> VB .method
ADO -> SQL
I have created some pages in ASP.NET and have started creating objects using source instead of designer.
I have automated some of the functionality on those pages using VB .method programing
While I have created some simple SQL select and bulk insert statements my SQL is still pretty weak and I haven't learned connection strings or driving changes back to the database using Transact-SQL
I am using a virtual dedicated server to host sqlexpress at a remote site. I can't get the connection from MS SQL Server Management Studio Express to connect over the Internet. I only have the box IP address (xxx.xxx.xxx.xxx) and have tried various forms of xxx.xxx.xxx.xxxsqlexpress as the server name.
Can someone point me in the right direction please?
Thanks, John
hi all
When I use asp.net 2.1 to connect sql 2005 express locally I got error message to say

that under the default settings SQL Server does not allow remote connections.
(provider: SQL Network Interfaces, error: 25 - Connection string is not valid)
I use following connection string
ConnectToDb.ConnectionString = "Data Source=servername;InitialCatalog=PushToMail;Integrated Security=true";
for more information : when I open SQLEXPRESS this oblige me to inter
servername : servernamesqlexpress
authentification: windowsauthentification
and when i try this connection
ConnectToDb.ConnectionString = "Data Source=servernamesqlexpress;InitialCatalog=PushToMail;Integrated
Security=true";
l got this erreur "inorganised sequence space"
I see a few have had this problem but their answers didn't help.
My connection string:
"Data Source=.SQLEXPRESS; Integrated Security=True;AttachDbFilename=|DataDirectory|TestApp.mdf;Initial Catalog=TestApp"
and the error a am getting is:
Cannot open database "TestApp" requested by the login. The login failed.
Login failed for user 'ComputerName\TheHaggis'.
Like i said it work a couple of times and then i get this error.
what am i do wrong
cheers

Hi there,
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!
Hello - where I can find the tools to view/see open connections, transactions not closed ... etc of a MS Sqlexpress database?
Thanks a lot - FOX
Hello, I had started my project with the express edition, then I switched to the pro one. The problem is that in my webconfig I still have .SQLEXPRESS and I don't know how to modify that to use the full version of Sql server. <add name="MyConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|MyDataBase.mdf;Integrated Security=True;User Instance=True"providerName="System.Data.SqlClient" /> When I look at the surface area manager I can see that I have 2 instances running : MSSQLSERVER and SQLEXPRESS.When starting Sql Server Management Studio I can connect to 2 servers: NEWDELL and NEWDELLSQLEXPRESS.And when I try to replace SQLEXPRESS by MSSQLSERVER in the connectionstring, then it doesn't connect.I remember having lost connection already when playing with all these tools, so I pay attention now ! That's why any help would be really appreciated ! Thank you.

Hi All,
I have created an installation application which will install the application with SQL Express and .NET Framework 2.0.
If i install this application in a Fresh system(i.e which is not having SQL Express), it is installing the application with new database instance successfully.
But if i try to install the same in a system which is already having SQL Express, throwing "Object reference exception" because it is not able to create the new database instance.
Can anybody help me out .
Regards,
Doppalapudi.
Because of numerous problems trying to get sqlexpress working, I uninstalled it with the intention of reinstalling (via Add or Remove Programs). However, now when I try to reinstall it, I get a message that the I am not making a changes so it won't let me install it.
I do have sql server 2005 developer's edition installed; is that the reason? and does that mean I cannot have both installed on the same machine?
Hi All,I've been struggling with this for hours...Could someone please advise me on how to convert my current File based SQL Server Express website to a Server based SQL Express one.Particularly interested in what I need to do in the SQL Express management tool, changes I need to make the projecvt itself and changes needed to get IIS to understand things have been changed.Thanks,Martin.
