   [.net] SendAsynch method
  A friend of mine and I are writing a network monitoring app in VB.NET. Right now, for scanning the subnet, it steps through and pings each address individually using the ping.send method. We want to speed it up using Ping.SendAsync, but have no idea as to how to use this. I can find any sample code in VB for it, and MSDN's explanation was no help. So, the question is : does anyone know of a sample we can look at?
