Hi,
System.InvalidCastException: Operator is not valid for type 'DBNull' for this line
If Not CType(objRow.Item("PLAN_DATE"), String).Length < 7 Then
objRow.Item("PLAN_DATE") = CType(objRow.Item("PLAN_DATE"), String).Insert(4, "/")
objRow.Item("PLAN_DATE") = CType(objRow.Item("PLAN_DATE"), String).Insert(7, "/")
End If
How its solve?
