It is my understanding that NetSend no longer exists in the new Windows VISTA O/S. We rely heavily on it and are looking for a replacement before updating our workstations. Can anybody provide an example of NetSend like functionality in VB.NET, possibly using the Microsoft Communication Foundation?

check the following link

http://www.ipmsg.org (and choose eng version from top-right corner), its not vb.net app, but for sure its VC++. So this is much advanced and faster.

(Btw: I don't know is this thread is suitable in this section or not, anyway.)
