i ask thread safety in c++ (using posix threads c++ wrapper ex.) when single instance/object of class shared between different threads. example member methods of single object of class called within different threads. should/can thread safety? class { private: int n; public: void increment() { ++n; } void decrement() { --n; } }; should protect class member n within increment/decrement methods lock or else? static (class variables) members have such need lock? if member immutable, not have worry it, right? anything cannot foreseen now? in addition scenario single object within multithreads, multiple object multiple threads? each thread owns instance of class. special other static (class variables) members? these things in mind, believe large topic , glad if have resources , refer previous discussions that. regards suggestion: don't try hand. use multithread library 1 boost: http://www.boost.org/doc/li

i coming onto project looks in landscape view. when switch portrait, looks elements stay , things not resized fit view. of content on pages might not fit in portrait mode @ based on how things laid out in landscape. if want make app in both orientations, best bet play around resizing on size inspector views items fit fine. and views items not fit easily, rethink design , either use ipad functionality popover, or create separate view display data differently instead of resizing? thanks. quite bit can achieved playing resizing controls in ib (especially ones stick control side - may not obvious, "stiking"the control that's on top bottom side). however, more robust solution have method reposition/resize controls depending on screen size (1024x768 or 768x1024). call whenever device rotated. such method quite handy other purposes - e.g. if have view visible (like ad), you'll need resize rest non-full-screen size.

i'd follows, using lambdas , linq expressions in c#. public class foo { private someentity entity; public foo(someentity entity) { this.entity = entity; bar(p => p.firstname); bar(p => p.surname); } public void bar(expression> barexpression) { // here? } } every time call bar(), i'd dig expression, , find out property referring (e.g. firstname or lastname), , someentity object working with. need value of property (this in fact important). eventually i'd extend bar more this, simple can "boil" experiment. thanks! public void bar<t>(expression<func<someentity, t>> expression) { string name = ((memberexpression)expression.body).member.name; } should name; there no instance in p => p.firstname ; this.entity should give want. value t value = expression.compile()(entity)

i have list of dependencies (or better dag without cycles): input (for example): item depends on nothing item b depends on c, e item c depends on item d depends on e item e depends on what i'm looking is: "what best* parallel order of items?" *best means: maximum concurrency level result (for example): [a], [e, c], [d, b] the best approach seems pseudocode getting order based on dependency think miss basic algorithm on this. this looks lot http://en.wikipedia.org/wiki/program_evaluation_and_review_technique/http://en.wikipedia.org/wiki/critical_path_method assuming want maximum concurrency level thing done possible, once have organised things takes no longer critical path have best possible solution - , if there no limit on amount of parallel tasks can run, can critical path scheduling every action of dependencies have completed.

if put classes of project in same namespace classes available everywhere in project. if use different namespaces not classes available everywhere. restriction. does using namespaces affect compile time somehow? since compiler has less classes in each namespace , not namespaces used time may have little less trouble finding right classes. will using namespaces affect applications performance? it won't affect execution-time performance. it may affect compile-time performance, doubt significant @ all, , wouldn't predict way affect it. (do have issue long compile times? if so, may want try , measure difference... otherwise won't know effect. if don't have problem, doesn't matter.)

my issue involves relationships , cascaded effects between properties, , i’m wondering best practices on this. i have class contains list of varying length of numbers. when editing list, user prefer set targetsum, program enforces list add sum. accomplishing programmatically setting final element in list such list sum = targetsum. example, if user chooses usetargetsum, sets targetsum = 10, creates list of length 4, , enters 1, 4, 2 first 3 elements, final element programmatically fixed 3. user cannot change final element themselves. i behind scenes handling necessary events, such list element value change, list length change, , usetargetsum option change. each event trigger, recalculates last element’s value. it works there bug when loading saved data. if list loaded sequentially adding elements, handlers modify each entry. regarding example, when first value of 1 entered, handlers “a value added, sum should 10, there 1 element, needs 10”. first element gets changed
