  • 1. SQL Server: get column's default value
    Hi all, whena I fill a DataTable with the .FillSchema method of the sqlDataAdapter class, I lose column's default value. Is there a simple way to get them or have I to query the SQL Server database and manually set them? Thanks
  • 2. Validating an XML file
    Hi there, I've created a strongly-typed "DataSet" using VS. If I save the data via "DataSet.WriteXml()" and later prompt my users for the name of the file in order to read it back in again (using "DataSet.ReadXml()"), how do I validate that the file they enter is valid. That is, while "DataSet.ReadXml()" throws a "System.Xml.XmlException" if they enter a non-XML file, a valid XML file results in no exception even though the schema may be completely incorrect (if they enter some random XML file on the system that is). Is there a clean way of detecting this situatiion. Thank you.

  • 4. Iterate a datatable filtering on the default view.
    I have a data table for which I have set the default view's rowfilter. If I bind to a control everything is fine. If I go through the table with a foreach I see everything, not my filtered data. How would I iterate through with respect to the rowfilter? MyDataset.Tables["row"].DefaultView.RowFilter = "region='US'"; foreach (DataRow dr in MyDataset.Tables["row"].Rows) { this.lblFilter.Text = lblFilter.Text + " --- " + dr["region"].ToString(); } TIA, Chris

The user instance login flag is not supported on this version of S

I copied a C# project from one machine to another both XP Pro with VS2005.

Then solution compiles but when I run the app I get the error message on the 
first dataadapter.FILL() command:

"The user instance login flag is not supported on this version of SQL 
Server. "

SQLExpress and SQ 2000 is installed, but I am specifiing SQL Express in the 
connection string see below and the SQL 2000 server is not started.

Do I need to uninstall the SQL 2000 server?  Shouldn't this work with the 
SQL 2000 on the same machine?

When I just remove the "User Instance =True" from the connection string I 
still get this message.  What am I doing wrong?

 <connectionStrings>
        <add name="CMMB1.Properties.Settings.CallMasterSQLConnectionString"
            connectionString="Data 
Source=.\SQLEXPRESS;AttachDbFilename="C:\Program 
Files\CALLMaster\Data\CallMasterSQL.mdf";Integrated Security=True;Connect 
Timeout=30;User Instance=True"
            providerName="System.Data.SqlClient" />
    </connectionStrings>

Thanks

Hello Morris,

You needn't to uninstall SQL 2000. It sounds like you disabled user 
instance on your SQL Express server.
Please run the following code on your SQL Express server to enable 
UserInstance.
sp_configure 'user instances enabled','1'

For more detailed information, please refer to
 http://www.**--****.com/ 
[User Instances for Non-Administrators]

Hope this helps, please try the above method and let me know if this method 
resolve the issue. We will follow up. It's my pleasure to assist you.
Have a great day,
Best regards,
Wen Yuan

2.Alternative for user instance login flag ?

I have SQL Server 2008 Developer Edition only installed on development
PC, have 2008 Standard Edition on the production server. The DBAs have
the production environemnt locked-down.

I created a VS.NET 2008 web application and setup a MDF to use my Dev
Edition DB instance. When I run the app, I try to connect and get

"
The user instance login flag is not supported on this version of SQL
Server. The connection will be closed. 
"

I understand that only SqlExpress supports this functionality. The
professional DBAs are not going to let me just install another
instance on the DB farm. So what is a good workaround or technology to
use something like user instances on Dev Edition and Standard Edition?


Thanks.
