Hi,

I have a form which has object, string and numbers.

I need a function to pass values of these to return DBNULL if value is null else return the value as is. Looking for a single function to handle all this

Any help ?

numbers cannot be null unless its Nullable like Nullable(Of Integer) and so on.
for object and string u can check if null and return DBNull.
    Private Function Validate(val As Object) As Object
        If val Is Nothing Then
            Return System.DBNull.Value
        End If
        Return val
    End Function

hi!

Something like this would help you:

Public Function IsNull(obj As Object) As object
	Return IIF(obj.Equals(Nothing), DBNull.Value, obj)
End Function
