i have controller serves delegate 2 scrollviews placed in view managed aforementioned view controller. to distinguish between 2 scroll views i'm trying use switch statement (instead of simple pointer comparison if statement). have tagged both scroll views 0 , 1 this nsuinteger const kfirstscrollview = 0; nsuinteger const ksecondscrollview = 1; when try use these constants in switch statement, compiler says case statements not constants. switch (scrollview.tag) { case kfirstscrollview: { // stuff } case ksecondscrollview: { // stuff } } what doing wrong? this can solved through use of anonymous (though not so) enum type: enum { kfirstscrollview = 0, ksecondscrollview = 1 }; switch (scrollview.tag) { case kfirstscrollview: { // stuff } case ksecondscrollview: { // stuff } } this compile without errors.

i have been using z shell while now, , starting curious. 1 thing have stumbled @ when writing own functions "autoload". according zshbuiltins(1) man page autoload "equivalent functions -u " (with exception), "equivalent typeset -f " (with exception). however, after looking @ autlooad use of, functions/prompts/promptinit , think have idea does. i think of autoload as, well, kind of "import" statement. but why "autoload foo" superior "source bar"? don't that. as stated in zsh documentation : a function can marked undefined using autoload builtin (or functions -u or typeset -fu ). such function has no body. when function first executed, shell searches definition using elements of fpath variable. [...] autoload allows functions specified without body automatically loaded when used ;) source takes argument script executed in environment of current session - i.e. retain changes scr

how previous 3 months in php ex(if dec.. should display previous 3 months i.e., oct nov dec) you can use magical strtotime function this: echo date('m', strtotime('-3 month')); so specify previous dates minus sign. echo date('m', strtotime('0 month')); echo date('m', strtotime('-1 month')); echo date('m', strtotime('-2 month')); echo date('m', strtotime('-3 month')); results: dec nov oct sep you can same if using loop this: for ($i = -3; $i <= 0; $i++){ echo date('m', strtotime("$i month")); } results: sep oct nov dec check out documentation see many other friendly date , time keywords strtotime supports: http://php.net/manual/en/function.strtotime.php

we have report users can run needs select records 5 different services. right not, using union combine tables in 1 query, sometimes, server , crashed! optimized bits , pieces of query (where's , table joins) , there haven't been crashes since, report still takes long time load (ie query slow). the question is, mysql perform faster , more optimally if create 5 temp tables different service types, , select of temps? or there different idea? could, of course, use 5 separate selects , combine them in code (php). imagine cause report load slower... any ideas? usually limiting factor in speed database, not php. i'd suggest running seperate queries , let php combining, see if faster. if you're not storing data in arrays or doing other heavy processing, suspect php way faster. (this meant comment don't have rights yet..)

i'm using rails 3 one. i've got collections model, user model , intermediate subscription model. way user can subscribe multiple collections, particular role. however, don't want user able subscribe same collection twice. so in subscription model i've got like: validate :subscription_duplicates def subscription_duplicates self.errors.add_to_base "this user subscribed" if subscription.where(:user_id => self.user.id, :collection_id => self.collection.id) end however seems ugly. also, breaks when want following in collection controller: def create @collection = collection.new(params[:collection]) @collection.subscriptions.build(:user => current_user, :role => subscription::roles['owner']) @collection.save respond_with(@collection) end when build subscription not have id "called id nil" error. thanks guidance! use validates_uniqueness_of validates_uniqueness_of :user_id, :scope => :collecti

if use assembly binding redirection redirect v1.0 referenced assembly v1.1 assembly, can use reflection apis to: create new classes introduced in v1.1 assembly invoke new methods of existing classes introduced in v1.1 assembly while keeping reference v1.0 assembly? mmmm, i'm not sure if makes sense. you need know class names , methods available @ 1.1 while coding against 1.0 version why not change 1.1 references? you can create instances name using activatior.createinstance().

i have , android emulator , microphone connected pc. want capture pcm pulses microphone (i.e. record voice) , send udp socket. please me in source code @ least voice recording. you can use code audio recording: mediarecorder recorder; void startrecording() throws ioexception { simpledateformat timestampformat = new simpledateformat( "yyyy-mm-dd-hh.mm.ss"); string filename = "audio_" + timestampformat.format(new date()) + ".mp4"; recorder = new mediarecorder(); recorder.setaudiosource(mediarecorder.audiosource.mic); recorder.setoutputformat(mediarecorder.outputformat.three_gpp); recorder.setaudioencoder(mediarecorder.audioencoder.amr_nb); recorder.setoutputfile("/sdcard/"+filename); recorder.prepare(); recorder.start(); } protected void stoprecording() { recorder.stop(); recorder.release(); }

i read couple of places people use messenger communicate between 2 different viewmodels. load viewmodels main viewmodel, wrong practice set property values using viewmodel instance in main viewmodel? mvvm great separating view code can better designer-developer workflow (i.e. designer can edit view in blend), , testing (i.e. can unit test logic without view, in headless mode). problem is, when people start using mvvm feel need other loose-coupling patterns to, ioc, di, etc ... basically, if you happy communicating directly between viewmodels (and yes, time), , can test code (that if choose test ... optional, don;t tell said that!). then, go it.

so have function calls web service return int indicitating success or various types of failures may have occurred. after recieve result service, run through switch statement , procceed accordingly based on encountered during service execution. private void example() { int result = executewebservice(); switch(result) { case 0: //no errors noerrorslogic(); break; case 1: // manual retry manualretrylogic(); break; case 2: // validation error validationerrorlogic(); break; default: // run time error occurred logicoptiond(); // @ point want to call service again once see if succeed break; } } generally, i'd add call function calls sevice , runs through results on again, don't want continuously run until service succeeds. in default option want force 'retry' calling service once - , process results accordingly. any ideas? you can alwaus do: private void example(bool retry = true) { .... default: if(retry) { example(false); } break; } just add

i've got access application update query following syntax: update table1, table2 set table2.value1 = table1.value1, table2.value2 = table1.value2, table2.value3 = table1.value3, table2.value4 = table1.value4 the query working not understand what's going on here. i'm trying convert query sql server. can please explain query does? guess it's special access syntax. thanks, sven it uses older implicit join syntax, although sql server should understand syntax too. it's inner joining table1 , table2, moving values table1 table2. because of lack of join conditions, if table1 has more 1 row may have unpredictable results. essentially is: update table1 inner join table2 <<on missing conditions here>> set table2.value1 = table1.value1 table2.value2 = table1.value2 table2.value3 = table1.value3 table2.value4 = table1.value4 you can convert sql server this: update table2 set table2.value1 = table1.value1

here's current code: $("#dialogscroll").dialog({ bgiframe: true, autoopen: false, maxheight: 600, width: 550, modal: true, resizable: false, open: function (type, data) { $(this).parent().appendto("form"); }, close: function () { } }); maxheight works great in firefox, chrome, etc. expected, ie 7 has problem it. have idea how ui dialog use maxheight in ie? <div id="dialogscroll" class="dialog" style="display:none; "> <table> <thead> <tr> <th> state code </th> <th> state name </th> </tr> </thead>

i try oauth (version 1.0) request authorization on server , using dotnetopenauth library this. server has troubles getting authorization parameters through authorization http header , request parameter "realm" required. have no idea how specify in dotnetopenauth library. appreciated! regards, alex you can't. @ least not through public api included in shipping version of dotnetopenauth. please jump on http://dotnetopenauth.uservoice.com/ , submit feature request detailing need. useful details might include whether need same value realm parameter requests, vs. needing customize individual requests.

update http://jsfiddle.net/musicisair/rsktp/embedded/result/ google analytics sets 4 cookies sent requests domain (and ofset subdomains). can tell no server uses them directly ; they're sent __utm.gif query param. now, google analytics reads, writes , acts on values , need available ga tracking script. so, wondering if possible to: rewrite __utm* cookies local storage after ga.js has written them delete them after ga.js has run rewrite cookies local storage cookie form right before ga.js reads them start over or, monkey patch ga.js use local storage before begins cookie read/write part. obviously if going far out of way remove __utm* cookies we'll want use async variant of analytics. i'm guessing down vote because didn't ask question. doh! my questions are: can done described above? if so, why hasn't been done? i have default html/css/js boilerplate template passes yslow, pagespeed, , chrome's audit near perfect scores.
