Checking if a public property has been set

[Maurd]

Hi,<BR><BR>I'm building a business object ("Public Class Database") with a public property "DataSet". What is the syntax for checking if the property Database.DataSet has been set or not? I thought it might be something like:<BR><BR> If IsNothing (Database.DataSet)<BR><BR>but that doesn't work, and I haven't found anything looking through the SDK documentation either.<BR><BR>Hope someone can help,<BR><BR>Thanks,<BR><BR>JON<BR><BR><BR><BR>+++++++++++<BR>Database.vb<BR>+++++++++++<BR><BR><BR>Imports System<BR>Imports System.Data<BR>Imports System.Data.OleDb<BR><BR>Namespace BusinessObjects<BR><BR> Public Class Database<BR> public DataSet as DataSet<BR> <BR> etc etc<BR><BR><BR><BR> public function CreateDataTableDefaultView(DataTableName as String, strQuery as string) as DataView<BR> If IsNothing (Database.DataSet) 'PRODUCES AN ERROR
