let's i've got java object that's got among others following methods: public string getfield1(); public string getfield2(); public string getfield3(); public string getfield4(); public string getfield5(); is there way iterate through these methods , call 'em following code? string fields = ""; for(int = 1; <= 5; ++){ fields += object.(getfield+i) + " | "; } thank upcoming ideas. there way using reflection: try{ method m= object.getclass().getmethod("getfield"+string.valueof(i), new class[]{}); fields+=(string)m.invoke(object); }catch(...){...} however: business smells of bad coding practice! can't rewrite getfieldn() methods this? string getfield(int fieldnum) you asking trouble creating numbered methods. remember reflection slow , should used when string-based method calls absolutely essential flow of program. use technique user-defined scripting languages have method by name . isn't case @ ...

not been able find definitive answer this, when client session established asp.net mvc2 application assume particular thread thread pool handles request. same thread handle subsequent requests session? in theory if somehow session id messed , wrong thread picked session level data missing? thanks in short, no, not under iis (i can't vouch "cassini" web development server in visual studio, doubt there too) you can demonstrate thread changing adding following view: <%= system.threading.thread.currentthread.managedthreadid %> now repeatedly hit page browser (or maybe hit 2 or 3 browsers) , see change time time. having said - in simple scenario such this, may often see same thread servicing request not worth asp.net creating more threads needs, once start loading server, see multiple threads.

i want write generic (c/c++) library use develop daemons in linux environment. rather reinventing wheel, thought i'd come in here find out if there known libraries in use. the library either c or c++ - although prefer c++ (maybe part of, or based on excellent boost library?). as aside, in terms of library selection criteria, since daemons pretty 'mission critical' components, better if library propose actively maintained group of developers (e.g. boost library [again]), has active community (or @ least mailing list resort when faced tricky situations), rather lone individual somewhere out there ... i saw document , starting point, dated, i'm wondering if there better , more known/used out there ... ? btw, developing on ubuntu (10.0.4) an alternative solution use process monitor such supervisord , manages multiple services, restarts them when crash, provides minimalistic web page view , control status of processes, can manage groups of services, sup...

i stress testing .net web application. did 2 reasons: wanted see performance under real world conditions , make sure hadn't missed problems during testing. had 30 concurrent users in application using during normal course of jobs. users had multiple windows of application open. 10 users: not bad 20 users: slowing down 30 users: very, slow no timeouts it loaded on production server. virtual server 2.66g hz xeon processor , 2 gb of ram. using win2k3 sp2. have .net 1.1 , 2.0 loaded , using sqlexpress sp1. we rechecked indexes on of tables afterword , should be. how can improve our application's performance? this thought of, check see how memory sql server using when have 20+ users - 1 of limitations of express version is limited 1gb of ram . might simple matter of there not being enough memory available to server due limitations of express.

i have following query: select column_name, count(column_name) table group column_name having count(column_name) > 1; what difference if replaced calls count(column_name) count(*) ? this question inspired how find duplicate values in table in oracle? . to clarify accepted answer (and maybe question), replacing count(column_name) count(*) return row in result contains null , count of null values in column. count(*) counts nulls , count(column) not [edit] added code people can run it create table #bla(id int,id2 int) insert #bla values(null,null) insert #bla values(1,null) insert #bla values(null,1) insert #bla values(1,null) insert #bla values(null,1) insert #bla values(1,null) insert #bla values(null,null) select count(*),count(id),count(id2) #bla results 7 3 2

those of have used pex , think advantages , disadvantages of pex tool? also, think advantages , disadvantages of "automated exploratory testing" in general, as supplement to tdd/unit testing? pex lets write parameterized unit tests. in sense, totally fits tdd/unit testing flow: write test, have pex 'explore' it, find failing tests, fix code, , forth. the big advantage can express tests classes of inputs, not couple hard-coded values. gives more expressiveness writing tests , forces think invariant/expectation code should fullfill (i.e. it's harder write assertions).

for example, if have 2 objects, 1 of type monkey , other of type dog, , both implement ianimal, this: interface ianimal { int numberofeyes {get; set;} string name {get; set;} } i want this: monkey monkey = new monkey() { numberofeyes = 7, name = "henry" }; dog dog = new dog(); myfancyclass.dynamiccopy(monkey, dog, typeof(ianimal)); debug.assert(dog.numberofeyes == monkey.numberofeyes); i imagine 1 can create class myfancyclass using reflection... clever person have idea? thanks, stephen a reflection based solution follows. note reflection work done once per type , cached, overhead should minimal. work .net 3.5 , not restricted interfaces. note use reflection properties on type t , filter properties have both getters , setters. build expression tree each property retrieves value source , assigns value target. expression trees compiled , cached in static field. when copyproperties method called, invokes copier each property, copying properties defin...

i'm experimenting html5 , websockets. know next nothing "ordinary" sockets. before messing websockets think might wise learn sockets. there online material should read or excersizes should go through myself speed? might worth pointing out i'm c# programmer mainly. thanks in advance! the short answer: nothing. websocket protocol high-level (layer-7) protocol; normal "sockets" think you're referring tcp sockets, more low-level, , programmed using berkeley sockets api. if want use websocket protocol on pragmatic level, need learn simple javascript api dealing same.

how implement draggable tab using java swing? instead of static jtabbedpane drag-and-drop tab different position rearrange tabs. edit : the java tutorials - drag , drop , data transfer . curses! beaten punch google search. unfortunately it's true there no easy way create draggable tab panes (or other components) in swing. whilst example above complete 1 i've written bit simpler. demonstrate more advanced techniques involved bit clearer. steps are: detect drag has occurred draw dragged tab offscreen buffer track mouse position whilst dragging occurs draw tab in buffer on top of component. the above example give want if want understand techniques applied here might better exercise round off edges of example , add features demonstrated above it. or maybe i'm disappointed because spent time writing solution when 1 existed :p import java.awt.component; import java.awt.graphics; import java.awt.image; import java.awt.point; import java.awt.rectangle...

i want know if possible colorize numbers in lstlisting package latex. example want numbers in red, 0x0f (hex) , 0b00001111 (bin): void setapwm2(unsigned char porcento) { //100 * 256 = 25.600 unsigned int val = porcento * pr2; val /= 25; //garante que tem apenas 10 bits val &= 0x03ff; //os 8 primeiros bits são colocados no ccpr1l ccpr2l = val >> 2; //os últimos dois são colocados na posição 5 e 4 ccp1con ccp2con |= (val & 0b00001111) << 4; } if there no way, there other package can it? ps: i'm working c language. thanks minted uses python library (pygments) , can kind of highlighting latex able understand code , not keywords listings does. at least hex supported directly, in pygments demo fails binary numbers , fine if add on line highlighter code (probably regexp similar 1 parses hex). edit: in pygments\lexers\compiled.py line 60 has: (r'0x[0-9a-fa-f]+[ll]?', number.hex), which parses hex c. add below (r...

i apply logic page containing checkboxlist control when user checks or unchecks individual checkbox items. say, instance dynamically show or hide related control. i came way using asp.net 2.0 callback mechanism (ajax) combination of client-side javascript , server-side logic in code-behind. however, solution not bullet-proof (i.e. suffers timing issues). not portable, because code needs know sequential ids of individual items, etc. the code came separated in 2 functions, 1 handling onclick event, , other processing returned callback string : <script type="text/javascript"> function oncheckboxclicked() { // gathers semi-colon separated list of labels, // associated checked items var texts = ''; // iterate on each individual checkbox item // items in checkboxlist sequential, // stop iteration @ first missing sequence number (var index = 0; index < 99; index++) { var checkbox = document.getelementbyid('c...

i found this page describing muenchian method, think i'm applying wrong. consider return set of ages: /doc/class/person/descriptive[(@name='age')]/value 1..2..2..2..3..3..4..7 but nodeset 1 node each age. 1..2..3..4..7 each of these seem return of values, instead of unique values: /doc/class/person/descriptive[(@name='age')][not(value=preceding-sibling::value)]/value /doc/class/person/descriptive[(@name='age')]/value[not(value=preceding-sibling::value)] what missing? here's example: <root> <item type='test'>a</item> <item type='test'>b</item> <item type='test'>c</item> <item type='test'>a</item> <item type='other'>a</item> <item type='test'>b</item> <item type='other'>d</item> <item type=''>a</item> </root> and x...

i'm trying tags working in rails application , want use acts_as_taggable. firstly followed instructions found in rails recipies (a free sample bit online) used acts_as_taggable plugin. however, found this site seems have gem acts_as_taggable more advanced (has options related tags etc). i've tried follow instructions there install it, keep getting errors. firstly installed gem normal ( gem install acts_as_taggable ) , tried various ways rails recognise , load gem. require_gem listed on site didn't work (i assume old command has been removed) , neither did straight require (although has worked bluecloth gem). i've tried using config.gem 'acts_as_taggable' keeps telling me haven't got acts_as_taggable installed , asks me run rake gems:install . no matter how many times run still gives error! the result of gem query -l -n acts_as_taggable lists acts_as_taggable installed local gem. i've tried running gem check , doesn't show problems...

in our environment have lib folder contains various third party assemblies referenced our projects. example, enterprise libary , elmah. sometimes dev doesn't latest on folder. when dev loads project can't find assembly in expected folder, visual studio automatically locates copy , updates project references. the problem occurs when dev checks in project , screws else up. is there way stop visual studio 2008 doing this? update: wanted add using tfs source control. here's how guard against @ company. (your mileage vary!) any non-system (or otherwise non-gac) references come our dev server, every developer has mapped w: drive. have common dll directory, subdirectories client (or vendor), , further subdirectories appropriate. no dlls ever stored in source control, except license.dll needed infragistics occasionally. for vendor-provided libraries (entlib, infragistics, etc.), policy reference w: drive. period. no 1 authorized reference anywhere else. ...

i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...

i rendering rails partial , want alternate background color when renders partial. know not super clear here example of want do: row 1 grey background row 2 yellow background row 3 grey background row 4 yellow background sorry stackoverflow seams prevent background colors being shown think makes idea clear this view code using <table> <%= render :partial => 'row' :collection => @rows %> </table> the _row.html.erb partial looks this <tr bgcolor="#aaaaaa"> <td><%= row.name %></td> </tr> the problem not know how change background color every other row. there way this? you use cycle helper. this: <tr class="<%= cycle("even", "odd") %>"> <td><%= row.name %></td> </tr> or in case use bgcolor instead, although recomend using css classes. you can cycle through more 2 values: cycle(‘first’, ‘second’, ‘third’...

in c#, want initialize string value empty string. how should this? right way, , why? string willi = string.empty; or string willi = string.empty; or string willi = ""; or what? use whatever , team find readable. other answers have suggested new string created every time use "" . not true - due string interning, created either once per assembly or once per appdomain (or possibly once whole process - not sure on front). difference negligible - massively, massively insignificant. which find more readable different matter, however. it's subjective , vary person person - suggest find out people on team like, , go consistency. find "" easier read. the argument "" , " " mistaken each other doesn't wash me. unless you're using proportional font (and haven't worked any developers do) it's pretty easy tell difference.

what benchmark test how hardware rates, asp.net, sql server, iis product? i have 2 servers, 1 runs code faster other , believe configurations close equivalent , therefore want benchmark two. i do not want question become 1 hardware. this question asking how test how hardware rates, software. in other words, 3d benchmark doesn't accurately rate system asp.net/sql server app. i single best solution i've found problem visual studio team test edition . can write stress tests in whatever .net language , learnable , discoverable. metrics informative. there 90-day trial may able away see talking about. had such experience @ previous company using bought outright @ present company , developer had never worked before had stress tests , running within few hours.

we have nightly build process automatically versions c++ projecs. here's how works. there's common header file versionnumber.h has specific #define version number. nighly build checks file out, increments integer behind #define , checks in. visual c++ projects #include header resource files , use define specifying version (version smth 1.0.3.thatnumber ). so far good. i'd have same c# class libraries built in same daily build. have [assembly: assemblyversion("1.0.*")] in assemblyinfo.cs files , libraries end 1.0.horriblenumber.anotherhorriblenumber version , 2 numbers don't correlate number used c++ projects. how have same determenistic automatic version numbering in c# projects minimal effort? firstly can specify full version follows: [assembly: assemblyversion("1.0.9.10")] secondly, common approach make little more straightforward (and echoes c++ approach) have single version.cs file (name unimportant) sits in common l...

are delegates same thing callbacks? or related somehow? a "callback" term refers coding design pattern, available in language has function pointers, or analogue function pointers (which kinda delegate is) in pattern, pass pointer function function, within called function, can "call back" function passed it. in way can control large chunk of internal behavior of method outside method, passing pointers different "callback" function each time call it... example of callback when have sorting algorithm has passed pointer function "compare" arbitrary pair of objects in list sorted, determine goes before other. on 1 call sort method, might pass callback function compares object name, , time pass function compares object weight, or whatever... a delegate, otoh, specific .net type acts signature-specific container function pointer... in .net managed code, delegates way create , use function pointer. in .net callback, in fact passin...
