i new java , in our code using gwt. we using keypressevent process key_enter request. seems, each enter request, 2 events fired keypressevent . expect 1 event should fired, since enter 1 time. the following code. please check , let me know, need correct .. void onenter(keypressevent event) { if(event.getnativeevent().getkeycode() == keycodes.key_enter) { //(seems times code called) //domy stuff } } if use event.getcharcode() instead of event.getnativeevent().getkeycode() , returns 0. any idea how fix. thanks, i prefer using keyupevent because user can't distinguish keypressevent here solution: void onkeyup(keyupevent event) { if(event.getnativekeycode() == keycodes.key_enter) { // handle key press } }

using level 11/3.0 emulator, 'settings' menu doesn't work. click on item eg. 'sound' or 'screen' , nothing happens beyond momentary high-lighting of item. in eclipse, logcat entry appears info/activitymanager(73): starting: intent { act=android.intent.action.main cmp=com.android.settings/.settings (has extras) } pid 375 and nothing else. what's going on here??? want change language settings default chinese! update: i've got screen set normal size(320x480) instead of default(and option) wxga. works fine if use wxga setting - new windows open etc. ver 3.0 tablets? thought system supposed gracefully accommodate different-sized screens. installed because ver 2.3 doesn't javascript bridge or location spoofing. it works me. make sure have "device ram size" setting avd set high. default 256, recommend 1024 (mb) if can spare it. can adjust via sdk , avd manager.

i have property defined retain attribute synthesizing: @property (nonatomic, retain) uiswitch *myswitch; and inside loadview doing this: self.myswitch = [[uiswitch alloc] initwithframe:cgrectmake(0, 0, 40, 20)]; and inside dealloc doing this: self.myswitch = nil; am leaking object (myswitch) have used 1 alloc? should autorelease while assigning frame? please suggest. the line: self.myswitch = [[uiswitch alloc] initwithframe:cgrectmake(0, 0, 40, 20)]; actually calls retain twice - once alloc , again in assignment self.myswitch (which property you've specified should retain values assigned it.) fix have been told best add call autorelease on line, making it: self.myswitch = [[[uiswitch alloc] initwithframe:cgrectmake(0, 0, 40, 20)] autorelease];

does know how ee determines path given template group modules. example, have installed module , there template files uses outside of templates directory use. not trying understand how works, how remove reference can move templates own directory. hmm. i'm pretty sure sort of information exist within each module's folder. if you're using ee2.x, folders within /system/expressionengine/third_party/ . if you're using ee1.x, folders within /system/modules/ . don't think i've come across module renders own templates inside of own before. may ask module you're using?

why following jquery code doesn't work when used django while works if loaded static page? there's django's csrf protection involved somewhere, can't find how make work. edited, stripped down code: $(document).ready(function(){ $('.content').load('something.txt'); $.ajax({ method: "get",url: "http://something.com/pm/js/something.txt", success: function(html) { $(".content").html(html); } }); }); the purpose of should be: when django page loads, script should call django view(s) , load data them. (at moment make easier 'something.txt' static file) ...firebug doesn't show abnormal i'm going take wild guess: maybe when load page django don't have static file serving setup properly, jquery never gets loaded, , such none of javascript gets executed. to check , see if jquery getting loaded open firebug on page , see if jquery varia...

this stupid question, i've been wondering while. c (or other low-level language, matter) have source, or compiler part "does work", including parsing? if so, couldn't different compilers have different c dialects? stdlib factor this? know how works. the c language not piece of software defined standard , 1 wouldn't it's open-source, rather it's open standard. there gazillion different compilers c however, , many of indeed open-source. notable example gcc's c compiler , under gnu general public license (gpl) , open-source license. there more options. watcom open-source, instance. there no shortage of open-source c compilers, without doubt widespread one, @ least in non-windows world, gcc. for windows, best bet watcom or gcc using cygwin or mingw .

evening! i need write reduce function in scheme works built-in reduce function in python. it's easy write reduce function in scheme: (define (reduce fn lis identity) (if (null? lis) identity (fn (car lis) (reduce fn (cdr lis) identity)))) however, code isn't identical python reduce , takes 2 arguments (the function , list of items reduce). can help me write scheme function works way? (>(reduce * '(2 4 5 5)) => 200, our professor's example.) thanks much, guys , gals. helpful <3 eta: mr. levien , mr. jester-young, thank much. provided perfect amount of information me figure problem out on own. *hug that easy. accumulator initialized first element of list: (define (py-reduce f ls) (fold f (car ls) (cdr ls))) (py-reduce * '(2 4 5 5)) => 200 feel free use reduce function fold srfi-1 (like reduce, fold-right ...) or use own. list needs 1 element @ least.

i'm building web app - in php - need pull down messages twitter , various other services (email, sms). i'm writing small service in node.js handle twitter connection etc. trying work out best content pulled down. right i'm leaning towards combination of mysql our standard info main php app , redis node.js service store each message against key username , sort of unique identifier. i've used redis before data needs persist rather being can expire sessions. redis' in memory nature makes me bit nervous as, on time, being our main message store dataset become unruly in ram, not? this blog post gives , concise overview nosql-type databases. perhaps can find confirmation or alternative redis there. since have not given numbers on how many , how need pull data sources, it's hard answer side. and, redis supports 2 methods of persistence: timed snapshots , append-only journal files changes db written to. second 1 safer alternative.

i banned forum asking first question, indeed stupid one. later created new logins, cleared browser history, changed ip address, still forum catches me , gives warning "you're banned". how able track me? seems eying me cam. it ip address, surprised if rely on track given user, given many users' ip address change 1 day next, because of block ip address allocation. a few other possibilities: lso (a.k.a., 'flash cookie') not stored in browser-specific directory. local storage , stored in localstorage directory 1 level below directory each browse, , have extension localstorage (on mac, anyway). both of these have stored in different directory default browser cookies , both have far higher storage capacity cookies way. there's nothing inherently 'stickier' either of these versus cookies, other fact not stored in same directory cookies , major version of major browsers include simple user-preference settings remove cookies--i...

i worked on project on .net , part of code involved reading header , footer pre-defined format consistency across various websites shared same client. i faced similar problem in php. contents of header/footer links using: <?php $contents = file_get_contents('http://www.mysite.com/common/footer.asp'); echo $contents; ?> is there way can load cache avoid repeated calls http://www.mysite.com/common/footer.asp cheers if looking cache across many page loads, use session. session_start(); $_session['somekey'] = value; or persistent storage flat file , database or memcache .

if wanted able sync computer phone. send messages computer phone (texts messages , custom phone application) parameters need connect 2. , find information on how might this? it seems me use of word "sync" in context going confuse people. i think (if understand correctly) want have custom phone app, can "talk" custom app on computer or server. correct? if so, in concept you'll need do. build custom phone app can talk "tcp/ip" (either known protocol such http or custom tcp/ip protocol design, if you're not done tcp/ip before complex). build custom application runs on desktop. if you're decided use http, app asp.net application or wcf application (self hosted or iis hosted) in scenario, phone app 1 can initiate communication because tcp/ip client (it doesn't have it'll simpler build initially). desktop application have running prior phone app attempting "connect". since tcp/ip server application. the phone...
