concurrency - Modeling synchronization using actors -


i'm trying understand how solve dining philosophers problem using actors. in case don't know, crux of problem thread needs obtain 2 locks before can proceed...and there multiple threads vying these 2 locks.

here's 1 way can model using actors:

# asynchronously request locks 2 forks (both forks actors) lock1 = fork1.future.lock lock2 = fork2.future.lock  if lock1 && lock2 # wait both locks   ... critical section end

but think result in deadlock if 2 threads have 1 lock each , waiting other thread give lock.

in general, how model accessing 2 resources atomically using actors?

there implementation of solution problem written in scala using akka actors here.

i have detailsview control on page used edit various fields of record, works in respect. i looking way add 1 column (and if works, why not more) right, absolutely read-only, show same fields of record comparison purposes. i aware there no obvious way such thing out of box detailsview . have looked other controls (transposed gridview , recommended formview , listview ), nothing satisfies. have special data binding setup using detailsview , can't out of without losing features. anyone on how "hack in" additional columns (for display only) on detailsview ? the solution have now, use second detailsview , visible set false in aspx. in code, make sure databind hidden detailsview hosts data third column first, initial detailsview named itemdetails . and in item created event, pass third column html rendering of hidden controls (in last code block) : protected void itemdetails_itemcreated(object sender, eventargs e) { if (dataite
