NoteNote

If the SqlCeConnection goes out of scope, it is not closed. You must explicitly close the connection by calling Close or Dispose.

The following example creates a SqlCeConnection, opens it, executes a query, and then closes the connection.

Dim conn As SqlCeConnection = Nothing

Try
    conn = New SqlCeConnection("Data Source = MyDatabase.sdf; Password ='<pwd>'")
    conn.Open()

    Dim cmd As SqlCeCommand = conn.CreateCommand()
    cmd.CommandText = "INSERT INTO Customers ([Customer ID], [Company Name]) Values('NWIND', 'Northwind Traders')"

    cmd.ExecuteNonQuery()
Finally
    conn.Close()
End Try
