No,
the catch will fall until it finds a match, then the catch routine is
completed. The preferred way to catch exceptions is to go from most like
(Specific) to least likely (Unspecific)
try
catch(ex as mycustomexpection)
'We threw this one ourselves, its probably recoverable
catch(ex as TimeoutException)
'We took too long, but probably recoverable
catch(ex as applicationexception)
'Unexpected exception, in the application
'Report, log, and ask to stop
catch(ex as system.exception)
'Unexpected exception, not in the application
'Report, log and stop
finally
'Perform and ultimate clean up here
end try
Hope that helps.
