c# - How to figure out who owns a worker thread that is still running when my app exits? -

-

not long after upgrading vs2010, application won't shut down cleanly. if close app , hit pause in ide, see this:

alt text

the problem is, there's no context. call stack says [external code], isn't helpful.

here's i've done far try narrow down problem:

  • deleted extraneous plugins minimize number of worker threads launched
  • set breakpoints in code anywhere create worker threads (and delegates + begininvoke, since think labeled "worker thread" in debugger anyway). none hit.
  • set isbackground = true threads

while next brute force step, roll code point didn't happen , on of change logs, isn't terribly efficient. can recommend better way figure out, given notable lack of information presented debugger?

the other things can think of include:

  • read on windbg , try use stop anytime thread started. @ least, thought possible... :)
  • comment out huge blocks of code until app closes properly, start uncommenting until doesn't.

update

perhaps information of use. decided use windbg , attach application. closed it, , switched thread 0 , dumped stack contents. here's have:

i did search on , found posts related wpf guis hanging, , maybe that'll give me more clues.

the worker thread id seeing 0. framework thread , expected - not thread program has "spawned". if attach .net process see this. i'm not sure framework thread - not finalizer thread never thread 0. perhaps jit thread?

what more interesting main thread, appears hanging. concentrate on debugging main thread bottom out. has deadlocked window closed event handler waiting never happen example?

update

after reading stack trace main thread added question, interesting run test bottom out whether main thread stalled or whether idle waiting message (and waiting wm_close never received or never sent).

the code below can used manually send wm_close message application. wait program hang when have shut down, , run code. replace process name own.

update 2

ok, looks main thread , hung not processing wm_close or wm_quit messages.

please try , make smallest application can reproduce issue , post code.

example wm_close\wm_quit app

internal class program {     private const int wm_quit = 0x0012;     private const int wm_close = 0x0010;      [dllimport("user32.dll")]     private static extern bool postmessage(int hhwnd, uint msg, intptr wparam, intptr lparam);      private static void main()     {         process p = getprocess("your process name - no '.exe' required");          closemainwindow(p);     }      private static process getprocess(string name)     {         list<process> processes = process.getprocessesbyname(name).tolist();          if (processes.count != 1)         {             throw new exception(               "expected 1 process name '" + name +               "' found " + processes.count + ".");         }          return processes[0];     }      private static void closemainwindow(process p)     {         postmessage(p, wm_close, "close");     }      private static void quitapplication(process p)     {         postmessage(p, wm_quit, "quit");     }      private static void postmessage(process p, uint message, string name)     {         console.writeline("posting {0} message '{1}'...", name, p.processname);          bool succeeded = postmessage(p.mainwindowhandle.toint32(), message, intptr.zero, intptr.zero);          console.writeline("posted {0} message '{1}' (succeeded:{2}).", name, p.processname, succeeded);     } }

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
