How To Put Value In Control If There Is No Data In Table.

i am trying to get value from a table and put the vale in label control but i have null data in the table. if i have null data then i want the label to have " 1 " as the value.

this is my code. when i run this i get error.  Operator '=' is not defined for type 'DBNull' and string "". Dim conn As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString)

Dim cmd As SqlCommand = New SqlCommand("SELECT MAX(PageHit) From BusinessLog WHERE (BusinessID=@BusID)", conn)cmd.Parameters.AddWithValue("@BusID", strBusID)

conn.Open()

If cmd.ExecuteScalar = "" Then

lblHits.Text = "1"

Exit Sub

Else

lblHits.Text = cmd.ExecuteScalar()

Exit Sub

End If
