02-Private Sub FillPlaceOfWork()

Me.cmbPlaceOfWork.ItemsSource = (CType(DBRelated.GetDataTable("Select CME, FirstName As FullName From Personnel"), IListSource)).GetList()
Me.cmbPlaceOfWork.DisplayMemberPath = "FullName"
Me.cmbPlaceOfWork.SelectedValuePath = "CME"

End Sub

INFO: DBRelated.GetDataTable("Select CME, FirstName As FullName From Personnel")
The above function is from my class DBRelated and its just returning a datatable (i am using access as my backend db)
