in little app users can have @ 'more information' or send me feedback when click on the menu button (of device) @ every xml file of app. this code (when click on menu button): @override public boolean oncreateoptionsmenu(menu menu) { getmenuinflater().inflate(r.menu.menu, menu); return super.oncreateoptionsmenu(menu); } @override public boolean onoptionsitemselected(menuitem item) { switch (item.getitemid()) { case r.id.impressum: startactivity(new intent (this, moreinformation.class)); break; case r.id.feedback: /* * */ break; } return super.onoptionsitemselected(item); } now put code java classes. works i'd create class (let's call ismenubuttonpressed.class ) contains code above , i'd remove code above other java classes , call ismenubuttonpressed.class (in these java classes when menu button pressed). how can that? how pass informati...

i'm learning c++ (coming java) , discovered can pass functions around. cool , think immensely useful. thinking on how use , 1 of idea's popped head customizable class. the best example of train of though customizable classes (code) person class. person have functions pertaining p. later person may pick sword (s), person has access functions pertaining both p , s. are there limits or performance issues this? sloppy , plain frowned upon? any insight educational, thanks. ~aedon there slight performance hit since pointer or reference must dereferenced before calling function. this advantageous feature. many design patterns , polymorphism depend on pointers functions. check out "visitor design pattern". another usage table of functions. example, write generic menu engine displays different menus using different functions. also research "factory design pattern."

how can restrict user going away current tab. need show confirmation message save/discard changes before leaving current tab. how can implement functionality in jtabbedpane? you override setselectedindex in jtabbedpane object, called before change takes place. if this, remember call super.setselectedindex after displayed confirmation. alternatively, eng.fouad states, add changelistener , display confirmation message there, happens after tab has been changed, confirmation message display after new tab has been displayed on screen: http://www.java2s.com/tutorial/java/0240__swing/listeningforselectedtabchanges.htm the second option easier implement if can live fact new tab displayed when confirmation pops up.

i have win32 program that's built vs2008, code linked msvcr90.dll , msvcp90.dll. however, it's running code in dll (which can't modify) that's been built vs2005 , when code in dll prints clog stream via msvcr80.dll , msvcp80.dll. here's problem: if re-route std::clog in code, affect code built against crt 9.0 libs, code using older crt 8.0 wont have output re-routed. there way re-route clog stream in dll built against older crt? i've investigated calling getmodulehandle() , getprocaddress() on older crt dlls , have managed re-route c stderr stream (via _open_osfhandle , _dup2), c++ clog stream still seems unaffected. think need call ios_base::sync_with_stdio() in older crt lib couldn't valid address function. appreciated. thanks. build helper dll using vs2005 - dll should export functions setup need vs8 runtime.

i'm considering concepts behind multiprocessing, , i'm trying come reason why ready list used contains runnable threads aren't running, opposed list of runnable threads head of data structure being running thread(s)? thanks opinions. edit: let me clarify. far know, thread packages use ready list identify processes ready run, while running process identified separate variable. why don't include running processes in ready list data structure running thread @ head of structure, making thread package inclusive. multiprocessing cause problems in design scheme? because thread can run on 1 processor (core) @ time. list (queue, really) of threads ready run used scheduler when it's looking thread should run; if thread running on 1 cpu, can't run on cpu @ same time, scheduler not want @ (at time -- sometime later when it's not running , eligible run again, care again...)

what best (or any) open source libraries regular or context-free grammar inference set of examples believed generated common grammar? i'd prefer library in java, python or ruby, of course beggars can't choosers. i did googling, couldn't find actual implementations, though did find plenty of interesting references. this library looks interesting, couldn't find available download anywhere. edit (2011-11-14): clarity (though i'm not sure how misunderstood), question grammar inference, not grammar generation or parsing. in other words, given set of strings accord unknown grammar, find restrictive grammar satisfy. i have not used them yet, had identical question , (after searching) found these 2 libraries, @ least: libalf c++ gitoolbox matlab unlike other answers question, these actual grammar inference libraries rather parser generators .

i attending competition supposed answer couple of engineering , technical related questions. hope of guys me one. i've searched web couple of hours, can't seem make out difference in names used. saw article http://msdn.microsoft.com/en-us/library/dd793166.aspx on msdn, still can't make out answer. the question is: in team fitting solutions use team foundation server 2010 manage , build our c# , c++ code. team foundation server able build code using number of build agents , build services. default number of build agents can run on build service when build service installed on own dedicated server? one build agent per build service the default number of build agents defined number of processor cores on server hosting build service none, because build agent cannot run on server hosting build service; needs own dedicated server thanks work. it turns out correct answer answer number 2. found "if installed team foundation build service on own se...

please, me distinct result field. tried go many way, googled... can't ti. i tried add hashset, tried duplicatefilter. think collector without success. result. use java, lucene-2.9.3. example: some_id description 1 bbb aaa 1 aaa ccc 2 aaa ddd 2 fff aaa and if search description in result must distinct some_id (1,2). maybe have solution or have code example. thanks advance. the very-new (still patch) grouping module on https://issues.apache.org/jira/browse/lucene-1421 might relevant here. enables group hits according field. example, if group "author" documents having same author in same group.

i love write code this: class zebra { public lazy int stripecount { { return expensivecountingmethodthatreallyonlyneedstoberunonce(); } } } edit: why? think looks better than: class zebra { private lazy<int> _stripecount; public zebra() { this._stripecount = new lazy(() => expensivecountingmethodthatreallyonlyneedstoberunonce()); } public lazy int stripecount { { return this._stripecount.value; } } } the first time call property, run code in get block, , afterward return value it. my questions: what costs involved adding kind of keyword library? what situations problematic in? would find useful? i'm not starting crusade next version of library, curious kind of considerations feature such should have go through. i curious kind of considerations feature such should have go through. first off, write blog subject, amongst others. see old blog: http://blogs.msdn.com/b/eric...

given lxml.etree possible somehow construct object representation of tree, sub-elements can accessed in object-like fashion (with '.' operator)? i know lxml has library called objectify looks can constructed given raw xml , adding new elements tree still requires go through etree-like node creation. ideally want achieve is: tree = objectify( etree_root ) print tree.somenode.get( 'attrib_name' ) tree.somenode.set( 'attrib_name', 'some_val' ) node( tree.somenode, "somechild" ) tree.somenode.somechild.set( 'attrib', 'foo' ) i guess have override __setattribute__ respectively __getattribute__ operators. guess have subclass etree.element class achieve this. but, on other hand api quite impractical, since there might multiple child-nodes same tag name. to find elements can use xpath expressions, correllate idea. api follows: subchild = root.find('child/subchild')
