i have view created using default buttons , background in interface builder. app runs properly. added .png background images view , buttons. build app , run , updates not show. i've tried simple changing text of button or add button , changes not propagating. i've cleaned targets, manually deleted builds in finder, , have shutdown computer. else missing? this might sounds easy - sure linked view view controller in interface builder? i've done before forget link them

i'm dealing odd situation. i'm implementing attributed strings ios application, , had warning going in available ios 3.2 , above. because still support 3.1.3 on iphones, knew had weakly link coretext , compile time os check before using them. i weakly linked framework, out of curiosity used class , ran on 3.1.3 device... , works. missing here, i'm confused why isn't crashing. i'm 100% sure 3.1.3 device, nsmutableattributedstring hidden class on 3.1.3, , work because of dynamic nature of objective-c ? i author of ohattributedlabel class. using it! the behavior have strange, ohattributedlabel uses coretext framework draw nsattributedstrings on screen. as coretext available since ios 3.2, can't see how possible work under ios 3.2, ios 3.1.3…?

hello company bought woo theme wp , lightbox works in firefox not on ie8. i saw post here javascript related, dont want mess until guidance find issue. our site www.fiestatax.com , click on small thumbs in main page using ie appreciated sincerely,jim the images linking cmyk images, ie can't display. save them in rgb format.

i need find maximum of function: a1^x1 * const1 + a2^x2 * const2 +....+ ak^xk * constk = qaulity where xk>0 , xk integer. ak constant. constraint: a1^x1 * const1*func(x1) + a2^x2 * const2*func(x2) +....+ ak^xk * constk*func(xk) < budget where func discrete function: func(x) { switch(x) { case 1: return 423; case 2: return 544; ... etc } } k may big(over 1000). x less 100. best method? there techniques nelder-mead optimization (which believe gsl implements), techniques assume sort of special structure (i.e. convexity or continuity). depending on values of function, there may not exist unique optimum or optimum normal downhill method can find.

for pdp-11, how can change following snippet of assembly it's 2 instructions, yet same work these four? tst r0 blt label cmp r0, #75 bgt label i've never worked pdp-11, have experience way testing , branching works on x86 systems, , looks may similar. on x86 instruction set, "test" instruction equivalent comparison against 0; "less than" flag set if value less 0, etc. i'm going guess #75 means numeric literal in hexadecimal -- 0x75. if assumptions correct, code have there doing 2 signed comparisons: is (signed) value of r0 less 0? is (signed) value of r0 greater 0x75? if instead treat unsigned value, -- assuming pdp-11 systems use 2's-complement encoding -- values negative become values greater or equal 0x8000 (since pdp-11 16-bit system). thus, if unsigned comparison, checking against 0x75 take care of negative values well; smallest possible value becomes 0, acceptable tests here. i'm not sure whether unsigned compar...

is there performance degradation when use nullable value types instead of value types? as mitch wheat pointed above, no, should not worry this. i'm going give short answer reason now, , later i'm going discover more you're asking: write code correct. profile after writing find points causing grief. when have code uses nullable , have performance reasons , profile , can't find problem yourself, then come ask how make faster. no, overhead of using nullable intents , purposes not degrading. discover more you're asking: performance surprise "as" , nullable types why shouldn't use nullable types in c# c# performance gain returning nullable type sqldatareader alternatives nullable types in c# casting (int?)null vs. new int?() - better? boxing / unboxing nullable types - why implementation? now, having read pages, hope feel more enlightened.

this one's been irking me while. when i'm using mouse scroll wheel scroll , down in webpage, , flash movie comes path of cursor, scroll wheel stops working. also, when flash movie has focus, can't use browser shortcuts ctrl + l or ctrl + r . i'm writing flex application , i'd find solution, @ least users aren't plagued inconsistency of user interface behavior. i should think there way tell flash propagate such events mouse scroll wheel , keyboard input browser unless occur in element useful, in flex textarea. can't find solutions out there though, nor talking it. specifically, how can make that: when user scrolling mouse, browser scrolls unless mouse on flex container scrollbar, or component wants scroll. when user presses button or combination of buttons on keyboard, propagated browser unless there active keyboard listener, or cursor in text field, etc. communication between browser , flash done via externalinterface. externalinte...

in vc++ added new function , when clicking on goto definition showing error symbol not found .for old functions going definitions. visual studio's intellisense stuff takes while update either a) try again in few minutes or b) build application. if build fails should update database used intellisense. if else fails, d/b might corrupted. close visual studio, find , delete <solution>.ncb file , delete it. vs rebuild , should well. usually!

i had hard time trying word question properly, i'm sorry if seems confusing. i'm using flixel library in flash builder. may not important butcause knows little more me or little as3 see i'm doing wrong. anyway, i'm trying create 10 instances of square object made. have pass x y coordinate place , works. ive tested if do: var testsquare:bgsq; testsquare = new bgsq(0,0); add(testsquare); it works fine , adds square @ 0,0 told to, want add 10 of them move next 1 that's created 25 px right (because each square 25px) my problem ever see 1 square, it's making 1 instance of still. anyone possibly have idea doing wrong? var counter:int = 0; var bgsqa:array = new array; (var ibgs:int = 0; ibgs < 10; ibgs++) { bgsqa[counter] = new bgsq(0,0); bgsqa[counter].x += 25; add(bgsqa[counter]); counter++; } there's lot you're doing wrong here. first off, you're using pseudo-iterator (counter) access array elements ...

what difference between asyncpostbacktrigger & postbacktrigger? controls inside updatepanel default cause partial page update, controls outside cause postback, using these triggers possible change behaviour required. from http://seminaarit.codezone.fi/video/devdays-2007/track1/2/2-asp-dotnet_ajax_extensions.ppt : asyncpostbacktrigger converts postbacks async callbacks typically used trigger updates when controls outside updatepanel post back if childrenastriggers="false", can used specify controls inside updatepanel should call rather post back postbacktrigger lets controls inside updatepanel post back. typically used allow controls post when childrenastriggers="true"

i wondering people doing in order compile iphone applications optimizing them maximum speed rather size or tradeoff speed versus size. you should always, always profile code before making blanket assumptions or bad particular app. shark nice , able use hardware performance counters on device tell lots of low-level details how application running. on iphone 3gs, compiling thumb-2 doesn't incur performance penalty older thumb instruction set (it has native floating point, in particular). see this other question additional details. you can produce binaries more 1 instruction set in them , though i'm not sure if can "no thumb" arm6 (pre-iphone 3gs) , "thumb ok" arm7 (iphone 3gs, presumably ipad, don't know ipod touches) . edit: possible, brad explaining how. in many cases, optimizing size way optimize speed: squeezing code size, may fit better cpu's instruction cache, avoiding fetches memory. helps more executed tight loops.

the documentation win32 api pulseevent() function ( kernel32.dll ) states function “… unreliable , should not used new applications. instead, use condition variables”. however, condition variables cannot used across process boundaries (named) events can. i have scenario cross-process, cross-runtime (native , managed code) in single producer has interesting make known zero or more consumers. right now, well-known named event used (and set signaled state) producer using pulseevent function when needs make known. 0 or more consumers wait on event ( waitforsingleobject()) , perform action in response. there no need two-way communication in scenario, , producer not need know if event has listeners, nor need know if event acted upon. on other hand, not want consumers ever miss events. in other words, system needs reliable – producer not need know if case or not. scenario can thought of “clock ticker” – i.e., producer provides semi-regular signal 0 or more consumers count. , consume...

in perl, can this: push(@{$h->[x]}, y); can simplify following python codes according above perl example? if x not in h: h[x] = [] h[x].append(y) i want simplify this, because goes many places in code, (and cannot initialize possible x []). not want make function, because there no 'inline' keyword. any ideas? a elegant way (since python 2.5) use defaultdict "collections" module: >>> collections import defaultdict >>> h = defaultdict(list) >>> h['a'].append('b') >>> h defaultdict(<type 'list'>, {'a': ['b']}) defaultdict dict, provides default value using whichever constructor passed when created (in example, list). i particularly on setdefault dict method, because 1) define variable defaultdict, , no other changes required on code (except perhaps remove previous kludges default values); , 2) setdefault terrible name :p

i checking on retain count of objects nslog(@"r = %d", [aobject retaincount]; it seems lowest value can "r = 1", if deliberately add "release" calls [aobject release]; the "r = 1" limit holds if try put "release" , "nslog" test codes in object's dealloc method. the cocoa run-time seems neglect releases "r = 1" before crashing "exc_bad_access" @ end of sample program (without gc). my explanation (a guess) need r >= 1 object accessed. , cocoa run-time tries refrain letting object's retain count getting 0 prematurely. can confirm or correct me if wrong? when retain count of object reach 0 (i.e. retain count 1, , release has been called again), it's deallocated instead of bothering final decrement.

i have read many posts regarding detection of popup blocker javascript code still have not been able find answer problem having now. the problem when target url external website, browser (ie8) prevents access window object, or in other words javascript code window.open() returns null although popup allowed open up. in contrary, local page of site, javascript returns window object. thus seems there security settings somewhere in internet options prevents grabbing handler of opened window; in case, know how detect javascript? the code using follows , cannot detect situation: var popup = window.open("http://www.externalsite.com&param1=value1", "_blank", ""); if (!popup) { alert('cannot preview page because pop-ups blocked browser'); } else { if (popup != null) { popup.focus(); } } if open window crosses zones , integrity levels (e.g. intranet page running @ medium opens internet page running @ low; or internet site running @ ...
