as has spent around 10 years programming web applications adobe's coldfusion, have decided add asp.net string bow. for has spent long cf , underlying java, asp.net seems little alien me. how should go getting speed asp.net can dangerous it? need know c# @ great amount of detail? i want in position can build basic web apps can learn more doing tricky stuff. i'm maybe 6 months down same path, here thoughts experience far: the c# language shouldn't give problem if have experience java @ (or cfscript). reference, though, when starting, found csharp-station primer language basics. won't far asp.net side goes; syntax. more you'll familiarizing .net libraries. ide can enormous here. here 3 biggest differences found making transition: asp.net server controls - in coldfusion, have pretty direct control on html; work closely page. isn't case in asp.net. server controls meant relieve of lot of tedium, @ cost of maybe direct control. cf pr...

i feel ridiculous asking because seems should simple, have been unable discover answer question. i have free standing set of files not affiliated c# project @ reside in complicated nested directory structure. want add them in format different directory in asp.net web application working on; while retaining same structure. so, copied folder target location of project , tried “add existing item” lose previous folder hierarchy. have re-created directories hand, copied across on one-to-one basis, , added existing items. there many directories/items in case. so how add existing directories , files in visual studio 2008? drag files / folders windows explorer solution explorer. add them all. note doesn't work if visual studio in administrator mode, because windows explorer user mode process.

i'm sure others agree, when code hits pavement easier think of elements go application. meaning, once going, think of what's next because have reached point have design table or class. the drawbacks of approach obvious , don't need go it. the question is, of can't conceptualize design without "seeing it", how go design @ seat of our pants more structured methodology? the solution can think of detailed specifications, forces 1 think of how things going work. is case of how people think differently, or there else ignoring? well, don't know if quite asking, reading question reminded me of tdd (test driven development). the goal of tdd produce clean, testable code along suite of automated regression tests. it amazing me how clean code can end when go @ tdd... think problems, write tests it, implement make tests pass, refactor ensure code clean , readable. i don't think need lot of front design tdd, may help... i'm kind of ...

a database stores lot of credit card information inevitable part of system have completed. want though ultimate security of card numbers whereby setup mechanism encrypt , decrypt of ourselves cannot decrypt given number. what after way secure information down @ database level no 1 can go in , produce file of card numbers. how have others overcome issue? 'standard' approach this? as usage of data links private , secure , no transmission of card number performed except when record created , encrypted not worried front end end. well database oracle have pl/sql , java play with. there's no shortage of processors willing store cc info , exchange token can bill against stored number. gets out of pci compliance, still allows on demand billing. depending on why need store cc, may better alternative. most companies refer "customer profile management", , pretty reasonable on fees. a few providers know of (in no particular order): authorize.net c...

i using activescaffold in ruby on rails app, , save space in table have replaced default "actions" text in table (ie. "edit", "delete", "show") icons using css. have added couple of custom actions action_link.add ("move" , "copy"). for clarity, i have tooltip pop related action (ie. "edit", "copy") when hover mouse on icon. i thought adding simple "alt" definition tag, doesn't appear work. can point me in right direction? the alt attribute used alternative image, in case of image missing, or in text browser. ie got wrong, when made alt appear tooltip. never meant that. the correct attribute title , of course doesn't tooltip in ie. so, have tooltip show in both ie, , firefox/safari/chrome/opera, use both alt attribute , title attribute.

i’ve written html5 application ipad. has 1 input field. every time user comes page, popup keyboard appears. how can suppress default behavior within html5/js context? in app, if type in login & password, shows screen (without page reload). keyboard still exists, , have manually hide it. i’m not sure understand description of problem, seems incomplete. try re-stating it, see if understand correctly? the user opens safari on ipad the user types address of html5 app safari’s address bar, , taps “go” button the user taken app’s login page. tap username field, , popup keyboard appears. they type in username, switch password field, type in password, , tap “go” button. your app loads different content on screen via javascript. popup keyboard still present. if that’s problem you’re having, might worth calling blur function on username , password fields before load content of new page. might make keyboard go away. if html these fields looked this: <input t...

i have visual studio setup project use install simple winforms application. @ end of install have custom user interface page shows single check box asks user if want run application. i've seen other installers quite often. cannot find way setup project run executable after install finishes. ideas? note: cannot use custom actions because these used part of install process, want run installed application once user presses 'close' button @ end of install. i believe 1 of real limitations of visual studio installation project. need able modify last page of installation ui vs.net not give way this. modify tables in .msi after has been built vs.net overwrite these changes each time built. may able override last page using merge module include in installation project. either way need become familiar how ui dialogs authored in .msi , not trivial. you may want consider switching free script based installer or buy commercial setup authoring application (just don't...

when there post-condition, return value of method must not null, can done? i do assert returnvalue != null : "not acceptable null value"; but assertions turned off! so okay do if(returnvalue==null) { throw new nullpointerexception("return value null @ method aaa"); } ? or better use user-defined exception (like nullreturnvalueexception ) such condition? i see no problem throwing npe possible before jvm - in particular null arguments. there seems debate this, there many examples in java se libraries this. cannot see why npe should holy in aspect not able throw yourself. however, digress. question different. talking post-condition stating return value mustn't null. surely null in case mean have bug inside method ? how document this? "this method throws nullpointerexception if return value unexpectedly null"? without explaining how happen? no, use assertion here. exceptions should used errors can conce...

i have scrollbars using jscrollpane plug-in jquery. the scrollbar works, content ajax, every 'page' load, add re-initialization of scrollbars. when content shorter page, scrollbars not visible. this results in 10px space content, , annoying items using 100% of available space. anyone idea how make scrollbars visible when content not available? or alternative css way reserve space fine. if nobody finds better solution, i can modified jscrollpane plugin, show "track" bar, , if going hide scrollbar (because content smaller view) not append 'drag' bar. though not clean option. it should taken further, , disable / re-enable down buttons, adding css functionality not hover/active state's when disabled... better usability. still looking forward possible better solution, though feel have come possible solution there none out of box

when have method such following: public synchronized void addone() { a++; } it equivalent following: (correct me if i'm wrong) public void addone() { synchronized(this) { a++; } } but equivalent following method?: public static synchronized void addone() { a++; // (in case 'a' must static) } what synchronized block acts same static synchronized method? understand static synchronized method synchronized on class , not instance (since there no instance), syntax that? it equivalent locking on class object. can reference class object writing class name followed .class . so, like: synchronized(yourclass.class) { } see java language specification, section 8.4.3.6 synchronized methods : a synchronized method acquires lock (§17.1) before executes. class (static) method, lock associated class object method's class used. instance method, lock associated (the object method invoked) used.

how check whether file exists, without using try statement? if reason you're checking can if file_exists: open_it() , it's safer use try around attempt open it. checking , opening risks file being deleted or moved or between when check , when try open it. if you're not planning open file immediately, can use os.path.isfile return true if path existing regular file. follows symbolic links, both islink() , isfile() can true same path. import os.path os.path.isfile(fname) if need sure it's file. starting python 3.4, pathlib module offers object-oriented approach (backported pathlib2 in python 2.7): from pathlib import path my_file = path("/path/to/file") if my_file.is_file(): # file exists to check directory, do: if my_file.is_dir(): # directory exists to check whether path object exists independently of whether file or directory, use exists() : if my_file.exists(): # path exists you can use resolve() ...

if have query like, delete table datetime_field < '2008-01-01 00:00:00' does having datetime_field column indexed help? i.e. index useful when using equality (or inequality) testing, or useful when doing ordered comparison well? (suggestions better executing query, without recreating table, ok!) maybe. in general, if there such index, use range scan on index if there no "better" index on query. however, if optimiser decides range end being big (i.e. include more than, 1/3 of rows), won't use index @ all, table scan faster. use explain (on select; can't explain delete) determine decision in specific case. depend upon how many rows there in table what range you're specifying what else specified in clause. won't use range scan of 1 index if there index "looks better".

when want create 1 object of class, use singleton design pattern. want create maximum 3 or 5 objects of class. there way restrict maximum number of object creation in java? of course implement singleton-like feature rather easily, you're apparently looking object pool . there many implementations of such pools, notable 1 apache commons/pool

let's have function returns date: date myfunc(parama, paramb){ //conditionally return date? } is appropriate return null function? seems ugly because forces clients check null . the "null object" pattern implementation pattern addresses concern. i'm not huge fan of null object pattern, yes, makes sense return list, if empty, rather return null . however, in java, null date 1 cleared , has year 1970. what best implementation pattern here? the null object pattern not trying do. pattern creating object no functionality in it's implementation can pass given function requires object not being null. example nullprogressmonitor in eclipse, empty implementation of iprogressmonitor . if return "null" date, 1970, clients still need check if it's "null" seeing if it's 1970. , if don't, misbehaviour happen. however, if return null, code fail fast, , they'll know should check null. also, 1970 could valid date....

i find system.monitor confusing, although understand threading, locks, deadlocks, race conditions, dining philosophers , jazz. use manualresetevent() inter-thread co-ordination, know that's heavyweight kernel object, , system.monitor (enter/pulse, etc.) more efficient. i've googled , googled cannot find sensible example. i grateful if crew explain potentially wonderful construct me :-) here's simple example; call wait releases lock (allowing worker obtain it) , adds main thread lock-object's pending queue. worker obtains lock, , calls pulse : moves main thread lock-object's ready queue. when worker releases lock, main can resume work. note lock(obj) {...} compiler-candy monitor.enter / monitor.exit in try/finally block. [edit: changed sample move lock(sync) earlier, avoid (unlikely) risk of missed pulse] static void main() { object sync = new object(); lock (sync) { threadpool.queueuserwor...

i trying loop through each value in dictionary , go out , dictionary based on 1 of objects in first dictionary through each loop iteration: var dalbumphotos = {}; // holds list of photo objects var dalbumsandphotos = {}; // hold album | dalbumphotos each album for(var in dalbums) { dalbumphotos = getphotosforalbum(userid, accesstoken, a.id); dalbumsandphotos(a) = dalbumphotos; } i'm not quite sure how without index. need increment through dalbumphotos , append final dictionary album , it's dalbumphotos it looks you're using associative array in javascript should able change last bit of code be: for(var in dalbums) { dalbumphotos = getphotosforalbum(userid, accesstoken, dalbums[a].id); dalbumsandphotos[a] = dalbumphotos; }

which language quick gui app + sqlite database crud (2-4 tables). java, python? (please no jokes vbasic), reference, source code on? added: first idea: 1 database sqlite (win) + client gui app (win) clients table + orders table + others import, export database add, del, edit, etc. entries second idea: 1 hosted database (postgresql ,mysql) + web app client clients table + orders table + others import, export database add, del, edit, etc. entries thinking django, ror or local java(netbeans), python(wxpython+orm). ??? ruby on rails simple crud operations very - although doing more can little more complex (would require reading ror's way of doing things). latest version of rails automatically uses sqlite databases, , in fact whole database, , crud gui code can created 1 command ( scaffold ). if deployed can bit more difficult (although hear capistrano good) - local or intranet use that's i'd do.

i'd use doxygen document legacy code that's mix of c , x86 assembly language. assembly language not inline, in separate assembly-only files. recommended way deal assembly language portion? see question 12 of doxygen faq . dealing pure assembly files, or inline assembly inside c sources? assuming former, you'll have either write input filter transform assembly code c-like (easier), or write new parser (much harder).

we writing tests com library written in vb 6.0.the problem facing that, unable access events declared in vb( withevents). exception, "object not support set of events". how can overcome problem? your mocking framework problem here. mock object returned call: repository.dynamicmock<personlib.databasecommand>(); implements databasecommand class's interface, not mock events. therefore, when pass instance of mock object vb6 code, expects receive databasecommand object can raise events, won't work. when pass mock object personclass.init method, here simplified version of happening: the code gets line in personclass.init : set dbcommand = vdbcommand vb6 asks object on right-hand side of set statement if supports same events databasecommand class (vb6 because declared dbcommand withevents keyword, try set event sink receive events dbcommand object). the object passed in, however, being mock object , not real databasecommand object, doe...

suppose you're product manager internal enterprise web application has 2000 users , 7 developers. have list of 350 future features, each ranging 5 150 developer days of work. how choose features work on, , how run release process? here's i'm thinking: (skip if boring) release process. work on several features @ once, release each individually when it's ready. other option (what we've been doing point) pick out set of features, designate them "a release", , release them @ once (announcing via mass email). the advantage of shorter release process can release features finish development. advantage of bigger process it's easier organize. feature prioritization. put future features in spreadsheet columns feature, description, comments, estimate, benefit, (your) estimate, (your) benefit. give copies 2 senior engineers, other senior project manager , yourself. the engineers estimate features (how precisely? consulting each other?). determine...
