MS SQL Server Express connection error from VB.net Program
m
my Visual Basic.Net program. I am using connection string as "Dim
connectionString As String = "Data Source=.\SQLEXPRESS;Initial
Catalog=MgmtSystem;User Instance=True".
But it is giving me error as " Failed to generate a user instance of SQL
Server. Only integrated connection can generate a User Instance".
I can connect to this "MgmtSystem" database successfully using Microsoft SQL
Server Management Studio Express though.
What could be the possible reason for this error? How do I get the correct
connection string? and what does integrated connection mean? Your help will
be appreciated.
My application is in Access at the moment, but I am planning to migrate it
to Microsoft SQL Server Express 2005. I am completely new to Microsoft SQL
Server Express 2005 Express version.Fixed it by myself. I changed the connectiuon string to "Data
Source=.\SQLEXPRESS;AttachDbFilename=C:\Program Files\Microsoft SQL
Server\MSSQL.1\MSSQL\Data\MgmtSystem.mdf;Initial Catalog=MgmtSystem;Persist
Security Info=True;" ..and it worked..

MS SQL SERVER 2000 INSTALLATION
Hi,
I'm learning ASP.net and I just bought Visual Studio .net professional. I tried to install MS SQL server 2000 on my two computers. One OS is windows server 2003 standard edition and another is Win XP professional.
Both of them appeared SQL Server Upgrade Wizard "from server 6.5 upgrade to server 2000". I don't think I have server 6.5 installed and there is no server 6.5 application interface to run the server. What's the problem? I cannot run the Wizard successfully. Can I just ignore it?
Thank you,
William
It comes another question.
I'm learning Accessing and Binding Data. It's a sample from chapter 9 of the book "MICROSOFT ASP.NET PROGRAMMING WITH MICROSOFT VISUAL BASIC .NET"
I got the error message as followings. I think it is the problem from set up the ASPNET account. I used SQL Enterprise Manager to set up. It looks fine. I feel not. But I don't know how to check it.
And then I tried to open a command prompt and typed in
oSql -S(local)\VSdotNET DE
And Icannot get a 1> prompt.
I got the message:
usage: osql [-U login id] [-P password]
[-S server] ..
Can you let me know where the problem is?
Thank you very much!

Second you connect through the Datalink property at the top of Visual studio not through osql. Try the link below for data bind.
Hope this helps.

I got some information fromhttp://weblogs.asp.net/coltk/archive/2003/07/10/9920.aspx
So I fixed the problem by following the codes. I'm so happy to make a progress. All of you make the forum great.

MS SQL database not connecting problem
hi
I usually did my database in SQL Server Management Studio Express then when I was in Visual Studios I would connect to it in the server explorer tab but I wanted to try to do it through Visual studios so I took my database files then went to my app_data folder and added them as existing items. I then went back to the server explorer tab and set it up.
Everything thing seemed to set up but when I run it I get an error.
I get this error when it does conn.Open();
Error:
1System.Data.SqlClient.SqlException was unhandledbyuser code2 Message="Cannotopen database \"Japanese\" requestedby the login. The login failed.\r\nLogin failedforuser'HOWSER\\chobo'."3 Source=".Net SqlClient Data Provider"4 ErrorCode=-21462320605 Class=116 LineNumber=655367 Number=40608Procedure=""9 Server="localhost\\SqlExpress"10 State=111 StackTrace:12 at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)13 at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj)14 at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj)15 at System.Data.SqlClient.SqlInternalConnectionTds.CompleteLogin(Boolean enlistOK)16 at System.Data.SqlClient.SqlInternalConnectionTds.AttemptOneLogin(ServerInfo serverInfo, String newPassword, Boolean ignoreSniOpenTimeout, Int64 timerExpire, SqlConnection owningObject)17 at System.Data.SqlClient.SqlInternalConnectionTds.LoginNoFailover(String host, String newPassword, Boolean redirectedUserInstance, SqlConnection owningObject, SqlConnectionString connectionOptions, Int64 timerStart)18 at System.Data.SqlClient.SqlInternalConnectionTds.OpenLoginEnlist(SqlConnection owningObject, SqlConnectionString connectionOptions, String newPassword, Boolean redirectedUserInstance)19 at System.Data.SqlClient.SqlInternalConnectionTds..ctor(DbConnectionPoolIdentityidentity, SqlConnectionString connectionOptions, Object providerInfo, String newPassword, SqlConnection owningObject, Boolean redirectedUserInstance)20 at System.Data.SqlClient.SqlConnectionFactory.CreateConnection(DbConnectionOptions options, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningConnection)21 at System.Data.ProviderBase.DbConnectionFactory.CreatePooledConnection(DbConnection owningConnection, DbConnectionPool pool, DbConnectionOptions options)22 at System.Data.ProviderBase.DbConnectionPool.CreateObject(DbConnection owningObject)23 at System.Data.ProviderBase.DbConnectionPool.UserCreateRequest(DbConnection owningObject)24 at System.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject)25 at System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection)26 at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory)27 at System.Data.SqlClient.SqlConnection.Open()28 at Practice.Page_Load(Object sender, EventArgs e)in h:\Website\Japanese\Practice.aspx.cs:line 2829 at System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e)30 at System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e)31 at System.Web.UI.Control.OnLoad(EventArgs e)32 at System.Web.UI.Control.LoadRecursive()33 at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)34
This is what I have as my connection stuff
webconfig
1 <connectionStrings>2 <add name="Japanese" connectionString="Server=localhost\SqlExpress;3 Database=Japanese; Integrated Security=True"4 providerName ="System.Data.SqlClient"/>5 </connectionStrings>67
In my file
1 SqlConnection conn;2 SqlCommand comm;3 SqlDataReader reader;45string connectionString = ConfigurationManager.ConnectionStrings["Japanese"].ConnectionString;6 conn =new SqlConnection(connectionString);78 comm =new SqlCommand("SELECT HiraganaCharacter,HiraganaImage FROM Hiragana", conn);9 conn.Open();10 reader = comm.ExecuteReader(); Thanks Hi,
can you check your code connection string?
it would be usually in this format for SQLserver connection in the config file:
connectionString="Data Source=yourservername;Initial Catalog=yourdatabasename;User ID=userid"providerName="System.Data.SqlClient"
Hope this helps

MS SQL 05 auto increment
Hello,
Firstly Hello to everyone I'm new the forum and fairly new to .net
I'm working on web datbase application using visual studios 05 and MS SQL05 I've used 2003 (briefly) before but 2005 is very new to me.
To my problem I download the GUI interface from microsoft so I can now setup a local database and do my own testing.
I have created the table and fields with in it however on a particular table i have made a primary Key and left it as an INT but I would like to set it as auto increment ! I dont know how to select that option as i was used to mysql way of doing things or does this have to be done as a stored procedure ?
Any assistance much appreciated.
in the management studio you can right click on the table name and click on "modify table" then in the right pane select the column you want to set autoidenty on to and in the bottom pane check the Identity property.
MS SQL & Visual Studio 2005
While trying to install the version of SQL that comes with the VS 2005 Pro
I'm getting error messages and the SQL engine will not start. Is it
possible to have the SQL install on the same machine as the VS 2005 or do I
need to install the personnel edition instead? What should I do?

That should be possible.
