OpenLNS Programmer's Reference 195
For Each ... Next statements.
•
If you are developing your OpenLNS app in Visual C++,
you can browse a collection to find a particular item by
using the _NewEnum property. See the IEnumVARIANT
interface for details.
• If you are developing your OpenLNS app in Visual Basic,
you do not need to use the _NewEnum property because
it is automatically used in the implementation of For
Each ... Next statements.
• If you are developing your OpenLNS app in C#, you do
not need to use the _NewEnum property explicitly
because it is automatically used in the implemention of
foreach statements.
Availability Local, full, and lightweight clients.
