When I run the following code it thows the following error:

> 
> "Object reference not set to an instance of an object."
>

```
Protected Sub CreateUserWizard1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles CreateUserWizard1.Load

    Dim SQLData As New System.Data.SqlClient.SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ASPNETDB.MDF;Integrated Security=True;User Instance=True")
    Dim cmdSelect As New System.Data.SqlClient.SqlCommand("SELECT TOP 1 EmployeeId FROM a1_admins Order by Id DESC", SQLData)
    Dim label11 As Label = CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("Label11")
    SQLData.Open()
    Dim dtrReader As System.Data.SqlClient.SqlDataReader = cmdSelect.ExecuteReader()
    If dtrReader.HasRows Then
        While dtrReader.Read()
            label11.Text = dtrReader("EmployeeId")
        End While
    End If
    dtrReader.Close()
    SQLData.Close()
End Sub

End Class

```

How can I fix this?
