Subject: [Crestron] 3-series out of bounds array references FYI...


Here's a lowdown on a great "feature" in case anyone trips across it before you spend too much time tearing your hair out.

In the 2-series, if you have an array and attempt to access an element beyond what it's declared for, you get a zero result and (I believe) an error in the log. (A slap on the wrists, and obviously not the results you're expecting)

In the 3-series, however - the remainder of the code following the line the error is on is THROWN OUT like last week's rancid leftovers. You get an error in your log, sure - but anything that relied on the block of code completing ain't gonna get satisfied. (Y'know, like, turning off the semaphore on a parsing routine)

So make sure you do range checking before accessing arrays on the 3s... :(

Heck at least with VB in the old days you could at least On Error Resume Next ;)

Why do I sound so bitter this week?

I wouldn't really expect the code in a try to continue after being caught - unless I misunderstand your meaning.

Good to know that's there. Thanks Rob.

It would be great if that error entry was sent back as a TRACE as well so
that you get a nice notice in your face. The 3-Series log is so verbose
that items get lost quite easily after a day of loading and testing.
