Default I added a column to a table, but, I can't see it.

I ran the code below that adds a column to an SQL table.
I refreshed Data Sources, but, the new column does not appear.
I refreshed Server Explorer and the new column does not appear.
I tried running the code again and I got:
"Column names in each table must be unique. Column name 'CaseNbr' in table 'Patient' is specified more than once."
so the column did actually get added, but, I can't see it.

Imports System.Data.SqlClient
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim sqlConnection As New System.Data.SqlClient.SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirector y|\Patient.mdf;Integrated Security=True;User Instance=True")
Dim str As String = "ALTER TABLE Patient ADD CaseNbr Varchar(50)"
Dim command As New System.Data.SqlClient.SqlCommand(str, sqlConnection)
sqlConnection.Open()
command.ExecuteNonQuery()
sqlConnection.Close()
Close()
End Sub
End Class

Default

There are two ways I've found to get new column(s) to appear in the DataSet Designer.

1) Right-click on the table, choose Add Column and type in the information.

2) Delete the table from the Designer. Then right-click on an empty spot and choose Add Table Adapter.

If you find another/better way, please let me know. I'm tired of fighting with the Designer.

Karen
