Unhandled exception of type System.NullReferenceException occurred

Unhandled exception of type System.NullReferenceException occurred HERE: .DataType = System.Type.GetType

works great for second column in datatable aCol10. Actually, this column was once first, and I added one. I'm just slightly confused.

Any thoughts are apprectated!

Thanks


' Part Qty
Dim aCol0 As DataColumn
With aCol0
.DataType = System.Type.GetType("System.Integer")
.ColumnName = "QTY"
.Caption = "Quantity"
End With

' Part No.
Dim aCol10 As New DataColumn
With aCol10
.DataType = System.Type.GetType("System.String")
.ColumnName = "PN"
.Caption = "Part No."
End With

Is there a reason why you declare them differently? You Dim aCol0 as DataColumn and you Dim aCol10 as New DataColumn.
