c# - Stop a thread if it takes too long -

-

i new in windows phone development , trying create windows phone app using c#

thread t = new thread(doaheavywork); t.start();  if (!t.join(1000)) // give operation 1s complete {     t.abort(); }

i cannot alter doaheavywork function.

i need result omputed within 1 or 2 seconds, since may run long time.

i have read using abort wrong way.

i using above in photochoosertask complete function. first run executes fine. is, when click button select photo, doaheavywork function doesn't exceed 1 sec. if try second time, photochoosertask throws exception , stops.

is because aborted process in 1st run? or else? there other way it?

.abort() causes thread destroyed completely. if generating new thread each time in example, work. if using same t object, need create new thread object, can't run .start() on aborted thread.

however fact aborting thread concern. happens application when take more 2 seconds. should showing user, please wait, taking longer expected. doing in if block it. .join() won't stop thread if doesn't manage join.

edit

you have 2 options might want consider in rewriting section:

  1. backgroundworker - http://msdn.microsoft.com/en-us/library/system.threading.tasks.task.aspx
  2. thread task - http://msdn.microsoft.com/en-us/library/windowsphone/develop/cc221403(v=vs.105).aspx

tasks seem appropriate solution in scenario.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

algorithm - Testing tetrahedron-triangle intersection -

-
i want determine whether given triangle intersects tetrahedron. not want compute solution polygon(if exists) itself. there library/package/published practical algorithm can used solve problem directly (unlike attempt below)? i think last resort have use standard polygon-polygon intersection algorithm implementations solve problem indirectly . my attempt on problem: thought of breaking problem of polygon-polygon intersection. each triangular face(say t1 ) of tetrahedron , given triangle t2 , thought of doing following: compute intersection(a line) between planes corresponding each triangle, l1 . for each triangle: for each edge of triangle l2 , compute point of intersection p between l1 , l2 . test(maybe using parametric form) of l2 , if point lies on edge l2 . if both triangles t1 , t2 , there exists at least one edge on intersection point p lies, implies triangles(and hence given tetrahedron , triangle t2 ) do intersect. create orthonormal fr
