Hidden Features of VB.NET?

by

The Exception When clause is largely unknown.

Consider this:

Public Sub Login(host as string, user as String, password as string, _
                            Optional bRetry as Boolean = False)
Try
   ssh.Connect(host, user, password)
Catch ex as TimeoutException When Not bRetry
   ''//Try again, but only once.
   Login(host, user, password, True)
Catch ex as TimeoutException
   ''//Log exception
End Try
End Sub
