i'm relatively new objective-c , cocoa... i've been trying understand how correctly implement mvc pattern in cocoa/cocoa touch long time now... understand idea behind it; makes complete sense conceptually: model holds data, view user sees , can interact with, , controller acts bridge between two. view can't talk model, model can't talk view. got it. what doesn't make sense me how use mvc efficiently… if user can interact view, , interact (i.e. iphone app, user clicks/drags within subclass of uiview, triggering "touchesbegan" , "touchesmoved" methods, etc.), how view communicate these events controller? i've looked @ countless examples , forums online, have yet find simplified all-purpose way of achieving this… know how communicate controller through buttons, sliders, , other things can connect outlet, things don't have target-action mechanism, what's best way it? thanks in advance suggestions regarding do, or look. ...

hey, have been working on while, , can remebr brother stepped me through same alogorithm. basicly, adds ascii values of both characters key, , phrase. i can encrypt this: def encrypt(key, string): encoded = '' in range(len(string)): key_c = ord(key[i % len(key)]) string_c = ord(string[i % len(string)]) encoded += chr((key_c + string_c) % 127) return encoded but can't seem remember did far decrypting. difficult revers mod :p ideas? that's simple, let's see how works. first of all, encrypted message obtained subtracting key. enc = msg + key (mod 127) how can obtain original message? that's easy, subtract key in both side enc - key = msg + key - key (mod 127) and here get: enc - key = msg (mod 127) for more details, please reference modular arithmetic , think should belong 1 of group/field/ring. i'm not expert in math, deeper theoretical knowledge, can found them in number theory . here refi...

i have button trying add visibility attribute binds path. in cases path call , return visibilty(hidden or visible). if have button has datacontext set different binded path , try add visiblity stuff, visibilty binded path never gets called. if remove datacontext visibilty works fine. there kind of work around this? why happen? thank very much. <button visibility="{binding path=thisbuttonvisibility}" datacontext="{binding path=thisbuttondatacontext}" as set datacontext on button , make after databinding "inside" of button binding relative datacontext got set. searches property thisbuttondatacontext.thisbuttonvisibility. normally button inherits datacontext parent, set explicit 1 wont find anymore overlaying datacontext. so said: datacontext valid in element itself, not in content. so can do: move visibility in object thisbuttondatacontext , works

any way event, when wpf data binding update occurs? upd i'm developing custom control extending 1 of standard controls. need notification, when datacontext property of ancestor control changes, or data binding causes update of property of ancestor control. it sounds require: inotifypropertychanged implemented on view model. depends on implementation assuming you've followed mvvm. this allows carry out work based on value of bound property changing (and event being raised).

i'm developing heavily multi-threaded application, dealing lots of small data batch process. the problem many threads being spawns, slows down system considerably. in order avoid that, i've got table of handles limits number of concurrent threads. "waitformultipleobjects", , when 1 slot being freed, create new thread, own data batch handle. now, i've got many threads want (typically, 1 per core). then, load incurred multi-threading extremely sensible. reason this: data batch small, i'm creating new threads. the first idea i'm implementing regroup jobs longer serial lists. therefore, when i'm creating new thread, have 128 or 512 data batch handle before being terminated. works well, destroys granularity. i asked scenario: if problem comes "creating" threads often, "pausing" them, loading data batch , "resuming" thread? unfortunately, i'm not successful. problem is: when thread in "suspend" mode, ...

i trying apply same gradient per screen shot below using cggradientcreatewithcolorcomponents . this i'm using @ moment, it's not quite right , i'm after better way of trying guess these values. i'd know how determine these values code grabbed tutorial, didn't explain @ in terms of components are. cgcolorspaceref mycolorspace = cgcolorspacecreatedevicergb(); cgfloat components[8] = { 1, 1, 1, 1, 0.866, 0.866, 0.866, 1 }; cgfloat locations[2] = { 0.0, 1.0 }; cggradientref mygradient = cggradientcreatewithcolorcomponents(mycolorspace, components, locations, 2); i've played around , got picture: with colors: static const cgfloat colors [] = { 0.894, 0.894, 0.894, 1.0, 0.694, 0.694, 0.694, 1.0 }; using piece of code: - (void) drawrect:(cgrect)rect { cgcolorspaceref basespace = cgcolorspacecreatedevicergb(); cggradientref gradient = cggradientcreatewithcolorcomponents(basespace, colors, null, 2); cgcolorspacerelease(basespace),...

(note: won't work if user has disabled inertial scrolling)

as far understand, main purpose of dependency injection have dependencies separated declaratively, can review , change dependency structure easily...right? then using dependency annotations spread through out code, aren't going non-centralized system (similar simple new operator), harder tweak? @autowired / @inject annotations declare dependencies on interfaces rather on concrete classes (as in case of new ), still can control implementations should injected controlling beans declared in context. also, these dependencies can overriden manually. @component -family annotations can controlled well, since can exclude particular classes component scanning.

i have been trying write script start/stop service svcadm. not understand how pid of process executed /var/run/myprocess.pid? not clear me can not find on other scripts in /lib/svc/method writes /var/run. mean have explicitly extract target location of pidfile environment variable, let program query , write code put pid in /var/run/myprocess.pid file? the pid file created daemon binary itself, not service scripts. if code need portable non solaris 10+ oses, might use defines this: http://src.opensolaris.org/source/xref/amd/ibs-gate/usr/src/cmd/ipf/tools/ipmon.c#130

possible duplicate: how add more 1 row zend_db? everyone, i need have bulk insert in zend framework. normal sql have below query, want same in zend framework. insert `dbname`.'tablename` (`id`, `user_id`, `screen_name`, `screen_name_server`) values (null, '15', 'test', 'test'), (null, '15', 'test', 'test'); thanks. there's no way this, marcin states. if you'd messing around zend framework you'd try alter insert. you try make insert method can take array of arrays data. use arrays of data build bulk insert. for example, $data1 = array( ); //data first insert $data2 = array( ); //data 2nd insert //a zend_db_table object $dbtable->insert( array( $data1, $data, ) ); you have edit insert method bit detect multiple data inserts , build insert accordingly. unfortunately haven't looked how code built or put here use.
