i'm having lot of trouble dynamically adding subviews uiscrollview. scroll view works fine content created in nib since subviews displayed depend on data in application (a mixture of images, labels, radio buttons, etc.) need able create , display them dynamically. according i've read seems pretty straightforward on various sites , in apple documentation. in view controller's viewdidload, i've added following code, uilabel *testlabel = [[uilabel alloc] init]; [testlabel setframe:cgrectmake(50, 50, 100, 40)]; [testlabel settext:@"my test label"]; [scrollview addsubview:testlabel]; [testlabel release]; the label not appear in scroll view @ if add testlabel self.view, appears (but not in scrolling content obviously). tried adding code viewdidappear in case misunderstood order of events no luck. when checked debugger, noticed address of scroll view 0x0 assume means null reason explain why not working. under assumption if connected scrollview pointer ac...

can tell me how can set thread run of core of cpu? make thread with: createthread(0, 0, thread, (lpvoid)1, 0, 0); run @ 25% speed of cpu, because takes 1 core calculates. how can set use 4 full speed? a thread run on single core @ 1 time, though may switched between cores os. have application take advantage of more 1 core need more 1 thread. you can use createthread start these threads, or wrapper around such boost::thread , or new c++11 std::thread . if have 4 threads (including first one) app can run on 4 cores @ once. however, adding threads application not lightly. multithreading complex topic, , can hard right. there many more difficulties may encounter , sources of bugs in multithreaded applications in single-threaded ones. consequently, there many articles , books (including mine ) on topic of multithreaded programming. take slow, read extensively multithreaded programming, , @ whether best approach application, , how best make use of cores.

i have class computation using callbacks. callbacks need allocate data (dynamic arrays) needs live outside of callback scope not after class destructs. thought make vector of auto_ptr destructed automatically when class destructs: class myclass { vector<auto_ptr<myobject>> thingstodie; }; the problem have lot of objects allocated , don't share base type can't use 1 vector this, , making vector every type lot of work. hierarchy following: auto_ptr_base (virtual destructor) | auto_ptr<t> will solve problem because like class myclass { vector<auto_ptr_base> thingstodie; }; and destruction virtually dispatched each specialized type automatically. problem stl doesn't have hierarchy , don't want re-implement auto_ptr. there other solution this? you use vector<shared_ptr<void>> . read this: why std::shared_ptr<void> work

sometimes test intermediate value in method. method can't split. wonder if junit can test method unit. if can put breakpoint in method, , local value , assert it, better. if impossible, how solve kind of problem. adding break point not unit testing , in fact not testing @ all. can call checking there no such thing check driven development. anyhow, people new unit testing quite find issue want test private or local values let variable or method. when started tdd in fact quite phased myself. thing is, in unit testing purpose black box testing of particular functionality , possible outcomes that. happens inside black box not concern nor need unit test it. if feel testing intermediate value maybe method long , should split 2 or more testable small methods. , if can not done should not worrying testing them. if intermediate value getting value public method it's that method want test in separate unit test, not value inside method testing.

so, realize covers wide array of topics , pieces of them have been covered before on stackoverflow, such this question . similarly, partial string matching , approximate string matching popular algorithmic discussions, seems. however, using these ideas in conjunction suit problems both need discussed seems highly inefficient. i'm looking way combine 2 problems in 1 solution, efficiently. right now, i'm using appengine java , persistent datastore. annoying, since doesn't seem have arithmetic usage in queries make things easier, i'm considering doing precalculation , storing field in database. essentially, idea friend , having on how possibly implement system matching , more or less hoping suggestions on how make more efficient. if needs scrapped in favor of better exists, can handle that, well. let's start off basic example of i'd search for. consider following nonsense sentence: the isolating layer rackets principal beneath hypocritical r...

is possible use kind of 'critical section' safe following within action... public actionresult generatetasks() { string somedir = .... if (!directory.exists(somedir)) { directory.createdirectory(somedir); } ... } you can using system-wide mutex. process or app-domain locking primitives fail work under conditions (for instance when application pool recycled). however, specific case here that's not necessary: directory.createdirectory implement existence check on own, shouldn't need in regard.
