i looking @ cmis connectivity 1 of our internal applications. know cmis part of (or be) part of sharepoint, there workable c# api (the openapi c# project seems in initial stages)? thanks you talking sharepoint 2010 , difficulties around " cmis , sharepoint 2010 details hard find ". microsoft provided cmis connector sharepoint 2010 administrative toolkit (download) . the cmis connector sharepoint server 2010 includes 2 features: the content management interoperability services (cmis) consumer web part, can added sharepoint page. web part displays , lets users interact contents of cmis repository. the content management interoperability services (cmis) producer, allows applications interact sharepoint lists , document libraries programmatically means of interfaces defined in cmis standard. please note need sharepoint server 2010 - sharepoint foundation not enough.

i have page in user input content , save it. i have function sends data server using xmlhttprequest. requirement show progress percentage while data being saved. 1 know way this? i thought use swfupload, appears specific file upload opposed dynamic content upload. any appreciated. thanks latest xmlhttprequest level 2 spec has added support events. specifically, can show upload progress like: xhr.upload.onprogress = function(evt) { if (evt.lengthcomputable) { var percent = 100 * evt.loaded / evt.total; trace("[onprogress] " + percent); } } the issue today lacking of support in web browsers. you'll have work around via flash or channel server progress notification. can find many discussions in site.

for instance, suppose have code: def dump(): tcpdump = subprocess.popen("tcpdump -nli any", stdin=subprocess.pipe, stdout=subprocess.pipe, shell=true) outputfile = tcpdump.stdout line in outputfile: print line, how can serve output of such browser? since there no stopping point, have no idea hook polling loop. more that, print line works (i see lines dumped on terminal), browser not same lines, see below: class tcpdumphandler(tornado.web.requesthandler): def get(self): self.write("<form method='post' action='/log'><input type='submit'></form>") @tornado.web.asynchronous def post(self): tcpdump = subprocess.popen("tcpdump -nli any", stdin=subprocess.pipe, stdout=subprocess.pipe, shell=true) outputfile = tcpdump.stdout line in outputfile: print line, self.write(line) self.finish() ...

it's more of coding standards question one. 1 is, if can call "better" use in file upload handler scripts? i know fwrite() , it's accompanying methods reading , writing can in chunks using move_uploaded_file() more elegant , shorter code. thanks use move_uploaded_file() . checks ensure user not funny business. also, using fread() , fwrite() copies file, instead of moving it, few orders of magnitude more costly moving (which changes it's name , given source , destination on same partition).

i have long list of ids (integers) represents items in database: var idlist = getallids(); i have huge generic list items add database: list<t> itemstoadd; now, remove items generic list id in idlist. idlist simple array , subtract lists this: itemstoadd.removeall(e => idlist.contains(e.id)); i pretty sure lot faster, datatypes should use both collections , efficient practice subtract them? thank you! transform temporarily idlist hashset<t> , use same method i.e.: items.removeall(e => idlisthash.contains(e.id)); it should faster

is there shorter , better-looking alternative to (b == 0) ? 0 : 1; in terms of bitwise operations? also, correct sign (-1, 0 or 1) of given integer a using (a > 0) ? 1 : (a >> 32); are there shorter (but not slower) ways? personally i'd stick first option "equal 0 or not" option. for sign of integer, i'd use math.sign , assume jit compiler going inline - testing assumption benchmarks if turns out potential bottleneck. think readability above - first piece of code blindingly obvious. second isn't. i'm not convinced second piece of code works ... thought right-shifts masked bottom 5 bits, assuming int32 ( int ). edit: checked, , indeed current second piece of code equivalent to: int y = x > 0 ? 1 : x; the shift doesn't end in compiled code. take object lesson caring more micro-optimization readability. it's easier make code work if it's easy understand. if code gives wrong result, don't care ho...

does know differences between rxjs , knockout ? me on surface seem trying solve same problem, build event driven ui. has had experience both, how differ/ how similar? can describe them me choose? steve (the creator of knockout) explained difference on blog: i’m familiar rx javascript, having used heavily on big project, , in fact aspects of design of knockout made rx experiences in mind. the key difference between knockout’s implementation of observer pattern , rx’s knockout automatically infers associations , dependencies between observables regular procedural code without having specify them front though special functional api. wanted knockout use regular procedural/imperative-style code it’s more familiar , approachable developers. another difference rx optimised composing streams of events without state. @ first enthusiastic , functional purity, after time felt increasingly jumping through awkward hoops , had invent ways si...

ok, might seem confusing, basically, this: there's form on asp page (not .net), sends info ms sql 2000 based server, running on iis6 (i think, might iis 5.1). server configured accept digits, form not validated. so when user keys in alphabets, , submits, error displayed. have configured iis redirect different page based on http error code, ("sorry, page requested cannot loaded @ time"), i, developer, don't know error code about. is there way can configure error page 'onload' send email containing page address caused error, error message itself, time of error, current user that's logged in, etc.? i'm open solutions, client side javascript, or server side asp code... iis configs valid answers now.. lol... in iis, custom errors tab > change 500 error type url file 'error.asp' in error.asp, loop form, querystring , session elements , send error details home in on error. dim asperr ,asperrstr,intkey dim strquerystring...

i have number of applications using various web technologies such soap, wcf services, or simple xmlreader. seem suffer same problem of missing timeout , hanging infinitely if internet connection suffers problems @ wrong time. i have set timeout in scenarios small, e.g. wcf closetimeout="00:00:15" opentimeout="00:00:15" receivetimeout="00:00:15" sendtimeout="00:00:15" or soap _session.timeout = (int)timeout.totalmilliseconds; these timeouts hit, appears there special case if internet drops out @ right time, call hang , never time out (using synchronous calls). i considering starting timer every time make call, , using appropriate .abort() function if timer expires cancel call. however, wondering if there simpler way fix issue , ensure timeout gets hit. does know why occurs, , if clean/simple/good way ensure calls time out? i can guess @ why occurs, without giving solution :( i suspect it's getting caught on d...

i looking large amount (>100k @ least) of data web 2.0 sites research project. thinking of using exposed api data, scrapping work better in case? the api (less work compared writting scraper), have no idea how time need collect data, considering there time/call limit. i'm not saying there no limit in scraping though; curious better way of getting job done. if site provides api, use it. it's simpler, generic, , legal. if site kind of popular, find wrappers language you're using. of course, if develop scraper, won't have limitations, maybe site doesn't allow being scraped, , that's why have api users/developers. about jeffrey04 comment: let's see... moral thing. if want, can obtain amount of data several times without being blocked. can change user-agents , change ip after n requests (of course, of programatically), , tricks cookies , that's not idea. mean advice of not using website scraping not because of getting banned webs...

is possible define event on input fired upon these circumstances. a) called on blur of input if remaining conditions true b) if autocomplete list visible halt event until closed c) if autocomplete list closes without item being selected event fired d) if autocomplete list closes item being selected event not fired e) if reason blur caused because item in autocomplete clicked event not fired as can see event has quite bit it. cant use normal settimeout in blur event because user sitting on the autocomplete list without selecting anything. maybe set variable on autocomplete open know still open. if timer expires , autocomplete still open can reset timer. on close can unset variable. or on select of item can unset timer? what think? it's possible trigger own events using trigger function. means can call event @ separate points in code, don't have write complicated constructions. simply call this: $('.yourclass').trigger('myevent'); li...
