i have following output. <img width='70' height='70' class='centreimg' src="http://localhost/aktivfitness_new/assets/images/centre/centre1.jpg" /> there same outputs centre2.jpg etc. want replace centre1.jpg hover.jpg when hover. but when use following becomes centre1hover.jpg $(".centreimg").mouseover(function() { var hoverimg = $(this).attr("src").match(/[^\.]+/) + "hover.jpg"; ... something wrong match(/[^.]+/) + "hover.jpg part. how can this? thanks in advance. don't think easier: var newsrc = oldsrc.replace(/[^\/\.]+\./, 'hover.'); anyway: shouldn't use javascript hovers =) if there way: use it. not bad practice, it's not user friendly: when image loads when hover, user see 'flash' because entire image still has loaded = not pretty.

hi custom imageview setting bitmap this, in constructor. setimagebitmap(btm); in ondraw method im writing text like canvas.drawtext text showed , can move text around using ontouchevent. but text behind bitmap. i thought setimagebitmap(btm) part of canvas?? ide! when draw bitmap in ondraw this, screen black!! canvas.drawbitmap(bitmap, 0,0, null); if want imageview displays text , you're handling ondraw, why not draw bitmap manually canvas in ondraw? way have control on order of drawing. draw image canvas first , text, , text no longer obscured image.

example: class commoncontroller { @modelattribute("refs") public list getref() { ... } @modelattribute("refs2") public list getref2() { ... } } class mycontroller extends commoncontroller { @requestmapping("/my") public string request() { return "/my"; } } the modelattribute objects available on page? why wouldn't recommend it? for example - have 2 controllers create , edit. they use same references getting through @modelattribute , instean copy past better create parent class controllers. class referenceparentcontroller { @modelattribute("refs") public list getref() { ... } @modelattribute("refs2") public list getref2() { ... } } class create extends referenceparentcontroller { ... } class edit extends referenceparentcontroller { ... }

when use jquery's .load() function load next pages body not retrieve class of body of page. there way achieve this? thank :) here code: $(document).ready(function () { if(navigator.standalone){ $('a').live("click", function (e) { var link = $(this).attr('href'); if ($(this).hasclass('noeffect')){ } else { e.preventdefault(); $("body").load(link); }; }); } else { window.scrollto(0, 0.9); } }); so putting body inside body? not sure that'll work expected! some html helpful, i'm guessing problem is. in pages loading body, put them inside div instead of body tag. should avoid body inside body problem. edit: what do regular ajax call new html. remove current body, , append stuff ajax call html. i've never tried that, if can't change html getting back, it's best thing try....

i attempting move picturebox(picuser) , down via key press events. newer c# , able via vb. such confused problem following code: private void picuser_keydown(object sender, system.windows.forms.keyeventargs e) { if (e.keycode == keys.w) { picuser.top -= 10; } } there no "error" code, picturebox doesn't move. a picturebox has no keydown event. has previewkeydown instead , requires picturebox have focus. i suggest use keydown of form host picturebox instead , use same exact code: public form1() { initializecomponent(); this.keydown += new system.windows.forms.keyeventhandler(this.form1_keydown); } private void form1_keydown(object sender, keyeventargs e) { if (e.keycode == keys.w) { picuser.top -= 10; } }

in python, best way extract list of items following xml? <iq xmlns="jabber:client" to="__anonymous__admin@localhost/8978528613056092673206" from="conference.localhost" id="disco" type="result"> <query xmlns="http://jabber.org/protocol/disco#items"> <item jid="pgatt@conference.localhost" name="pgatt (1)"/> <item jid="pgatt@conference.localhost" name="pgatt (1)"/> </query> </iq> i use lxml xpath, it's not working in case. think problems due namespaces. i'm not set on lxml , open using library. i solution robust enough fail if general structure of xml changes. i'm not sure lxml can use expression //*[local-name()="item"] pull out item elements regardless of namespace. you might want take @ amara xml processing. >>> import amara.bindery >>> doc = amara.bindery.pars...

i have worker roles send out multicast messages using azure service bus. 2 of consumers of these messages websites hosted on azure. know there issues hosting service bus wcf endpoints in iis when running on premise. i've followed microsoft's advice , configured service host programmatically . one of websites has been using technique quite while. uses hosted web core (it developed before full iis option on azure) , initialises service host part of roleentrypoint.onrun() . i'm trying move site using full iis. because in full iis roleentrypoint runs in different process site , service host needs access static variables in site i've moved initialisation of service host global.asax application_onstart . code works fine when running website under iis locally , runs fine when running in compute emulator, once deploy cloud wcf host never seems receive messages. haven't been able catch errors occurring. has else out there deployed this?

what happens when casting between these 2 in relation termination character? in c99 objective-c. i assume char 8 bits on system in answer. if architecture uses unsigned char char type absolutely nothing happen. if architecture uses signed char char type negative values of char wrap around causing possibly unexpected results. never happen termination null character. please note, "casting" nothing happens, tell compiler interpret location in memory differently. difference in interpretation create actual (side)effects of cast.

what difference between kernel space , user space? kernel space, kernel threads, kernel processes , kernel stack mean same thing? also, why need differentiation? the really simplified answer kernel runs in kernel space, , normal programs run in user space. user space form of sand-boxing -- restricts user programs can't mess memory (and other resources) owned other programs or os kernel. limits (but doesn't entirely eliminate) ability bad things crashing machine. the kernel core of operating system. has full access memory , machine hardware (and else on machine). keep machine stable possible, want trusted, well-tested code run in kernel mode/kernel space. the stack part of memory, naturally it's segregated right along rest of memory.

i lift project have file called liftconsole.scala . generated project creation script , contains following import _root_.bootstrap.liftweb.boot import _root_.scala.tools.nsc.maingenericrunner object liftconsole { def main(args : array[string]) { // instantiate project's boot file val b = new boot() // boot project b.boot // run maingenericrunner repl maingenericrunner.main(args) // after repl exits, exit scala script exit(0) } } it seems purpose of file let user interact console within project. i'd that, never able because cannot find jar maingenericrunner. know it? my goal able initialize console project settings can execute project specific code. it part of scala-compiler.jar . can find rest of scala distribution. add project: val scalacompiler = "org.scala-lang" % "scala-compiler" % "2.8.1"

i'm trying animate backgroundcolor on uilabel achieve 'fade' effect. code looks this: uilabel *lbl = ... uicolor *oldcol = lbl.backgroundcolor; lbl.backgroundcolor = [uicolor bluecolor]; [uiview animatewithduration:1.0 animations:^(void) { lbl.backgroundcolor = oldcol; }]; but instantly reverts original colour. tried below, isolate problem: lbl.backgroundcolor = [uicolor bluecolor]; [uiview animatewithduration:1.0 animations:^(void) { lbl.backgroundcolor = [uicolor greencolor]; }]; and instantly goes green. ideas? background color of uilabel isn't animatable. see how animate background color of uilabel? possible workaround.

i , friend have project files connected dropbox. code same. then, when execute nsentitydescription *entity = [nsentitydescription entityforname:@"business" inmanagedobjectcontext:[bnutilitiesquick managedobjectcontext]]; i got something. same code set entity nil in friends' computer. the badgernew.xcdatamodeld that's used create managedobject changed. team have reset iphone simulator , deleted application iphone simulator whole thing created new again. doesn't work. not enough information give terribly useful answer. however, dropbox horrible way share project. if have multiple people working on same codebase, should using revision control tool of kind; svn , git being popular these days. grab source friend's computer , drop on own. diff two; opendiff mysource myfriendssource . see differs. if nothing differs (unlikely), there different in configuration of 2 machines.

what actually do? branched out project 1 app 6 different apps , forgot update installed_apps part of settings file. still works though didn't list new apps in. supposed happen? need include apps in installed_apps ? yes. installed_apps helps django sync database, run tests, urls work , more related issues. maybe installed apps still works because main 1 calls others imports, django app nothing more simple python module imported when called in settings file, that's why invalid syntax error after run development server because import won't work invalid syntax.

i of django beginner , have been trying decouple applications as possible , build in small re-usable pieces possible. trying follow james bennett's strategy of building re-usable apps . in mind, came across problem. let's had app stores information movies: the code this: class movie(models.model): name = models.charfield(max_length=255) ... now, if wanted add ratings, use django-rating , add field model: class movie(models.model): name = models.charfield(max_length=255) rating = ratingfield(range=5) ... this inherently mean movie app dependent on django-ratings , if wanted re-use it, no longer needed ratings, still have install django-ratings or modify , fork off app. now, around use try/except import , define field if successful, movie app explicitly tied rating in database table definition. it seems more sensible separate 2 models , define relationship in ratings model instead of movie. way dependency defined when use rating, not needed...

possible duplicate: c#: use of “ref” reference-type variables? hi, does make sense pass "reference type" method parameter 'ref' key? or nonsense reference type not value type? thanks! it lets change reference variable itself , in addition object it's pointing to . it makes sense if think might make variable point different object (or null ) inside method. otherwise, no.
