I have a function with about 10 arguments, one of the variables is failing, ie Object reference not set to an instance of an object.
Is it possible to determine which variable is causing the issue? Public Function AddCustomer(ByVal CustomerId As Nullable(Of Integer), ByVal Company As String, ByVal TradingAs As String, ByVal AccessName As String, ByVal Address As String, ByVal Address2 As String, ByVal Suburb As String, ByVal State As String, ByVal Postcode As String, ByVal CountryId As Integer, ByVal PostalAddress As String, ByVal PostalAddress2 As String, ByVal PostalSuburb As String, ByVal PostalState As String, ByVal PostalPostcode As String, ByVal PostalCountryId As String, ByVal Phone As String, ByVal Fax As String, ByVal Email As String, ByVal Firstname As String, ByVal Lastname As String, ByVal UserEmail As String, ByVal Username As String, ByVal UserPassword As String, ByVal Website As String, ByVal Mobile As String)
