i want move program pc problem images not loaded on other pc (source problem) . wondering if create folder exe placed , name resources , load every image there. image2.source = new bitmapimage(new uri(@"res\startoh.png")); you may add images resources visual studio project. packed assembly of executable , don't need copy them separately. create folder in project (let's called images ) , add images folder. make sure build action images set resource . now can create bitmapimage such resource appropriate pack uri : var uri = new uri("pack://application:,,,/images/someimage.png"); image.source = new bitmapimage(uri);

i try create function end game message counting down until ends, , having repeat block of code lot in text adventure game, decided make function of sake of neatness, , efficiency. cannot figure out how define , call such function. code trying execute: print "that\'s real shame..." time.sleep(1) print 'exiting program in 5 seconds:' time.sleep(1) print '5' time.sleep(1) print '4' time.sleep(1) print '3' time.sleep(1) print '2' time.sleep(1) print '1' time.sleep(1) sys.exit('exiting game...') break so defining function this: def exit(): print "that\'s real shame..." time.sleep(1) print 'exiting program in 5 seconds:' time.sleep(1) print '5' time.sleep(1) print '4' time.sleep(1) print '3' time.sleep(1) print '2' time.sleep(1) print '1' time.sleep(1) sys.exit('exiting game...') b

i'd develop abstract class extended fit custom requirements. of methods implemented in base class. however, rely heavily on values set in members, child class should define. reason i'm saying "abstract" class want force extenders of class define values members. possible? i know can define methods abstract , force extenders implement those. i'm not sure members. furthermore, design practice? example: abstract class foo_bar { // want child class define these private $member1 = 0; private $member2 = 0; private $member3 = 0; // child class , instances can access public function foo() { return 'foo'; } // child class must implement abstract function bar(); } in short: no. there's no such thing abstract properties in php. you may declare properties protected in abstract class child inherits them. if you'd declare them abstract , there's no guarantee child implements them with us

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers

i'm new ios , still trying wrap head around basics (my newbie disclaimer). i'm starting play persistent data , presenting data uicollectionview. i can create cells , right number arrays, i'm having issues right number of cells interacting core data. i'll try example clarify: have entity person attributes first name , last name. have 1 person saved. when number of objects in section, 1 object 1 person. number used create # of cells 1 1 person. i'd create 2 cells (one first name , 1 last name) each person, can't figure out. tried putting each entity own section , using arithmetic return 2 * #of entities in section, hat crashes. this seems rather simple can't figure out? in numberofsectionsincollectionview:: return 1; in collectionview:numberofitemsinsection:: return fetcheddata.count*2; in collectionview:cellforitematindexpath:: person *p = fetcheddata[indexpath.row/2]; // integer division ... cell.textlabel = indexpath.row % 2 ?

if have long-ish string of text , wanted pull out words greater 4 characters in length , found more 4 times in string, can linq that? you may able tighten up, believe effect of var results = inputstring.split() .where(word => word.length > 4) .groupby(word => word) .where(grp => grp.count() > 4) .select(grp => grp.key); you will, of course, need decide how wish deal punctuation might present. so given input var inputstring = @"the quick brown fox jumped on lazy dog quick brown fox jumped on lazy dog quick fox jumped on lazy dog quick fox jumped on lazy dog quick brown fox jumped on lazy dog"; the results contain "quick" , "jumped" because other word greater 4 characters ("brown") appeared 3 times.

how add prefix , suffix set of numbers obtained text file. have written coding it's showing bugs. my text file contain numbers like 1 2 3 4 5 6 and output should come 3r_1.pdb 3r_2.pdb . . 3r_6.pdb the program:- open(file,"text.txt"); open(out,">output.txt"); while($file=<file>) { $f= "3r_"; $e= ".pdb"; chomp($file); print out "$f$file$e\n"; } i unable understand bug actually. since pattern same here how it: use strict; use warnings; open(my $in, "<", "text.txt") or die $!; open(my $out, ">", "output.txt") or die $!; while (my $line = <$in>) { chomp ($line); print $out "3r_" . $line .

after going through many similar looking questions had no way put own question here. i need display image on swing application. source of image bitmap data retrieved ms sql server. have tried following ways try 1 - have tried creating imageicon bytes retrieved. no results. try 2 - saved bytes in .png file , tried loading using imageio . works fine on local machine fails on test server. both windows machines. try3 - on step 2 tried saving in different formats .png. not work @ all. please let me know missing? note : have tried including jai jars referenced libraries also. you should have stored hint format data has in database. if not, can hope imageio can handle it. there no need write data files (which pitfall in itself, where write them? think of restricted process privileges , disk quotas). create inputstream accesses data directly (e.g. java.io.bytearrayinputstream), way can have imageio load directly using stream based methods.

in image 's asdoc, can see : flex includes bitmapimage class. class used embedding images skins , fxg components but can use image in skins , use @embed image ... therefore, , when should use image or bitmapimage please ? image skinnable class wraps bitmapimage . such bitmapimage more lightweight, image has more features. question when use boils down this: if features of bitmapimage suffice, use that; otherwise use image. in mobile environments try favor use of bitmapimage. now features image add exactly? image extends skinnablecomponent: means can assign images skin border or dropshadow or whatever consistently throughout application. it provides progress indicator can displayed while image loading. one more feature possibility queue loading of multiple images .

i have stock lots of word (+200k) in java program , want access them fast. need know if given word belongs "dictionary". don't need pair <word, smthg> . if possible i'm searching solution in standard library. ps : maybe using data structure not better way ? reading each time file containing words more efficient ? edit : it's small project. have deal effectiveness , memory last edit : choose hashset. use java sets because sets linear sorted data structure treeset. searching, techniques binary search can implemented , fast no repetition. this structure of java sets. also not going allow duplication hence reducing redundancy , save memory. if want know various searching algorithms complexities refer link. here is http://bigocheatsheet.com/

the sonar metrics include section evaluating documentation quality, having item public undocumented api . high in our project because reports each , every unit test. however, unit test methods have public junit. is there easy way remove unit test methods undocumented api metric ? i'm aware of these alternatives: we add javadoc comments each test method. not useful, pollutes code. the tests in eclipse test fragment projects. exclude test classes sonar analysis. however, want have same rules applied test code , production code (e.g. when checking violations). i have not found section in sonar configuration matching metric, may have missed it. this metric not fed unit test classes, must have missed in configuration. as example, check out sonar analysed sonar (on nemo) : you'll see no test class reported "public_undocumented_api".

i trying make funny function rotates element 360. problem executes first time , don't know why! jquery.fn.circularfun = function() { this.stop().animate( {rotation: 360}, { duration: 500, step: function(now, fx) { $(this).css({"transform": "rotate("+now+"deg)"}); } } ); } thanks!! after first rotation, have been rotated 360 . need set 0 after you're finished.

i curious on basis ruby , ror versions named. example, after ruby 1.9.3, version 2.0 instead of 1.10 or 1.9.4, , in rails. there must convention or rule. ruby , rails, many other projects follow semantic versioning . they don't follow letter, though. example, ruby 1.9 backwards-incompatible ruby 1.8, whereas ruby 2.0 compatible ruby 1.9, ruby 1.9 should have been ruby 2.0 , ruby 2.0 should have been ruby 2.1. in particular case, there historic "marketing" reasons that: term "ruby 2.0" has been used in ruby community on 10 years mark specific "mythical" version specific, talked-about features scoped monkey patching , traits. releasing version without features still calling "2.0" have been more confusing breaking rules of semantic versioning. (actually, ruby 2.0 was released without traits , it has led confusion !) otoh, impossible call "1.10", because ruby_version constant returns version string , , lot of too

i making android app in make 5 tables in 1 open helper class. facing problem while having on delete cascade in schema. know concept of on delete cascade. here copy 1 of 2 tables. private static final string medicine_table = "create table medicine_details (_mid integer primary key autoincrement, " + " medicine_name text, type text, take_with text, m_did integer not null," + "foreign key(m_did) references doctor_details(did)" + " on delete cascade" + ");"; private static final string sch_tab = "create table schedule_details(sid integer primary key autoincrement, " + "medi_stdate text,medi_end_date text,time_sch text,rept text, alarm_id number, " +

i have fail pass string value label or text box after split function. question how store string value in label after applying split function. string strdata2 = "samsung,apple,htc"; char[] separator2 = new char[] { ',' }; string[] strsplitarr = strdata2.split(separator2); foreach (string arrstr in strsplitarr) { response.write(arrstr + "<br/>"); } (e.g. label.text = ""+ the split string value ) thanks you can use string.join : label.text = string.join("," , strsplitarr); concatenates elements of string array, using specified separator between each element.
