i have project of eclipse located in folder on my local-disk. let's say: c:\proj1.0 , after while need change folder name proj2.0 (why? because started working on next version of application , want save time of creating new project in eclipse. older version stored in source control anyway) how can it? if try change project cannot found eclipse. didn't find eclipse configuration file absolute location of project defined. you have change project's name eclipse. in package explorer right-click project -> refactor -> rename . or click on project , press alt + shift + r . way no configuration lost. another way move project's folder right-clicking on project > refactor > move . alternatively, if renamed folder's name , cannot see project in eclipse anymore, can select file menu -> import -> existing projects workspace , navigate parent folder of project's folder, select projects want import , press finish.

i have jlabel icon , text. there possibility hide jlabel's text ? don't want hide whole component (setvisible(false)), text, icon remains visible. i'd still use gettext , settext methods. thanks help! as far i'm concerned, there's no direct way this. try of following: extend jlabel , override settext() , gettext() methods. these should store text give in new string field. every time call settext should delegate super.settext() label-text not invisible. add method switches visibility. if call settextvisibility() true, class should call super.settext() string of spaces. here's example of mean: public class mylabel extends jlabel { private string labeltext; private boolean labeltextvisible = true; private mylabel( string text, icon icon, int horizontalalignment ) { super( text, icon, horizontalalignment ); labeltext = text; } private mylabel( string text, int horizontalalignment ) { super( text, hori...

for diagnostic purposes, trying install android device 2 different versions of same app. in order accomplish that, duplicated project , changed the: project name package name app name (as appears in application's "android:label" in androidmanifest.xml) however, when install modified app, overwrites older app (with different project name, package name , app name). apparently, missing else needs changed, in order let both projects exist on android phone side-by-side. what "something else"? i think need change package name text in android manifest. if change package in eclipse properties menu project, doesn't change actual androidmanifest.xml. edit: package name identified in androidmanifest.xml unique indetifier application, think, perhaps, not referencing root package of android project's source code. think it's best practice them 1 in same, see release alternate version of app (i.e. paid vs free) changing manifest appli...

i in process of researching best "design-pattern" web api. using django web framework. created non-ajax interface causes entire page reload @ each request. now, starting incorporate ajax interface. sake of discussion, 2 example pieces of functionality need add api following 1) beta page: user supplies email address. want make ajax call serverside see if exists in db. initial design call view function similar to def check_email(request): if request.method == "post": # check db # return json true/false 2) profile picture uploads, new profile picture added page without full page reload as far can tell, best way via post call view function. then, response return json, can inject dom accordingly. can please let me know if on right track designing api? note: have checked out django-piston, , seems pretty useful also. thanks you're right on track, use request.is_ajax() check if it's ajax request return respon...

(i'm thinking opacity problems maybe?) if more complex shapes circles answer different? any other tips on improving performance? thanks lot! there several approaches might consider here: bet on vector renderer drawing lines , circles each frame. they'll re-rendered every time, that's flash heavily optimized for, it's not impossible faster alternatives.

is possible attaching profiler jvm (let's visualvm) make methods run slower, while not effecting others , causing skew in results makes piece of code hotspot when in fact it's not. ask reflection calls example. i'm running code shows lot of time spent in spring aop calls (specifically invokejoinpointusingreflection) - author says runs fine in testing (using in code microbenchmark) when profiled showed method take longer other non-reflection methods. (sorry if that' little unclear) got wondering if profiler have effect , lead developer down false trail. feel free answer examples, reflection part example. profilers regularly give mis-leading information, in right. tend skew result in simple methods might further optimised if profiling wasn't enabled. if in doubt suggest use profiler, such yourkit (evalation version should fine) has more light weight recording, can have same issues.

if multiple instances of singleton trying update same property simultaneously, there conflicts? how as3 handle order? flash single-threaded.. write order issue when becomes multi-threaded? apologies awkward wording - i'm new oop , design patterns, , still grasping basic. 'scuse newbieness... your question isn't worded - there lot of issues here, think understand you're saying. it's best start definition of singleton - singleton class allows 1 object instance made. such, cannot have multiple singletons. referring multiple references singleton object, though, make sense. as question - won't run 2 simultaneous updates, flash runs in single thread , sequential. thus, though as3 allows asynchronous events, 1 thing ever happens @ 1 time. as such, there won't conflict - singleton property reflect whatever touched last, if updates millisecond apart. hope made sense.

i use burn tool wix v3.6.1601.0 create bootstrapper download project dependencies (.net 3.5). end result 2 executables (a program msi , exe download dependencies). since many of customers seams not understand executable use, make simpler shipping 1 file (i.e. msi). is possible burn ?, , if can point me documentation on how create single msi bootstrap own dependencies. msi packages can't bootstrap other installers except through use of "embedded chainers." (see msi sdk topic on msiembeddedchainer.) burn creates .exe contains msis , other prerequisites.

i'm using doxygen eclox plug in on eclipse helios php project. nearly fine, but: the eclipse auto comment system generates style: * @param typename $parametername ...whereas doxygen expects opposite: * @param $parametername [typename] (actually, doxygen doesn't know type names in php, far can see - use convention of making them first word of comment). not mean i'm continually having delete "unknown_type" eclipse puts in, uses variable names comments in outline generator (rather variable names in code). having set comments work doxygen, outline generator has lost parameter names. does know how set eclipse/eclox/doxygen differently? this feature implemented in recent releases of doxygen. see https://bugzilla.gnome.org/show_bug.cgi?id=613185 @var , @return still not supported.
