I have a aspx pages that will restore a database when all the fields are populate by the Admin user. The first thing it does is check to see if there's any open connections. If there is let the admin user know by displaying all loginname via a label text box. However, I'm only able to get it to display the first row and only the first row. I wrote a store procedure that will query the master table in the database the Admin user is attempting to restore. What can I do this display all loginames? Any help is appreciated. Thanks

Here is the code that I'm using:


Private Sub CheckLiveConnections()

        Try

            'Define database connection

            myconnection = New SqlClient.SqlConnection("server=" & DropDownList1.SelectedItem.Value & ";user=xxxx; password=xxxx;database = ADMIN")
 

            myconnection.Open()
 

            Dim OpenConnections As New SqlClient.SqlCommand("EXEC GetConnections '" & DropDownList2.SelectedValue & "'", myconnection)
 

            'Call the sproc...

            Dim reader As SqlClient.SqlDataReader = OpenConnections.ExecuteReader()
 

            If reader.Read() Then

                Label9.Text = reader.Item(0)

            End If
 

        Catch ex As System.Exception

            Label9.Text = ex.Message

        End Try
 

    End Sub

>What can I do this display all loginames?
you need 2 things:
* an idea about how you want to display it (GUI)
* use a while reader.Read() instead of a if reader.Read() to loop through the records...

            myconnection.Open()
 

            Dim OpenConnections As New SqlClient.SqlCommand("EXEC GetConnections '" & DropDownList2.SelectedValue & "'", myconnection)
 

            'Call the sproc...

            Dim reader As SqlClient.SqlDataReader = OpenConnections.ExecuteReader()
 

            While reader.Read()

                Label9.Text += reader.Item(0) + "<BR/>"

            End While
 

        Catch ex As System.Exception

            Label9.Text = ex.Message

after reflection... you might want to use a listbox instead of a textbox, and show each item in a dedicated row of output... depends how you want to display the data...
