i've got scripts call different urls depending on if they're processed online site (release), or offline localhost (development). i'd find quick way find which. i can come few clunky ways this, there definitive, fast, elegant method? if(is_offline()) { ... } a variable called $_server["computername"] available on iis servers, can use determine if script running on development server or production server ( mymachine vs. www37 ). you can use $_server["http_host"] variable ( localhost vs. www.domain.com ). you can create empty text file on development server (careful not upload it) , use is_file() check if presence (is_file(".foo") == true vs. false ). you can check php_os if operating systems on 2 servers different ( winnt vs. linux ). you can check presence of path inside __file__ constant ( c:/inetpub/wwwroot/website/ vs. /home/www37/ ). a variant of 3: @include("override_server_with_local_config.php");...

i'm doing c++ project requires server create new thread handle connections each time accept() returns new socket descriptor. using select decide when connection attempt has taken place when client has sent data on newly created client socket (the 1 accept creates). 2 functions , 2 selects - 1 polling socket dedicated listening connections, 1 polling socket created when new connection successful. the behavior of first case expect - fd_isset returns true id of listening socket when connection requested, , false until next connection attempt. second case not work, though code same different fd_set , socket objects. i'm wondering if stems tcp socket? these sockets return true when polled select due streamy nature? //working snippet struct timeval tv; tv.tv_sec = 0; tv.tv_usec = 500000; fd_set readfds; fd_zero(&readfds); fd_set(sid,&readfds); //start server loop for(;;){ //check if listening socket has client requrests, timeout @ 500 ms int numsockets = se...

using type: class foo { public static implicit operator int(foo obj) { return 5; } } var test=new[] { new foo() }; the following works expected var ok=test.select(x => (int)x).tolist(); but using cast<> fails invalidcastexception - why? var fail=test.cast<int>().tolist(); read jon skeet's blog reimplementing linq (edulinq), part 33 , says this: it's worth noting (as of .net 3.5 sp1) cast , oftype perform reference , unboxing conversions. won't convert boxed int long, or execute user-defined conversions. follow same rules converting object generic type parameter. (that's convenient implementation!)

i've got little jquery plugin. there images in vertically scrollable div. can click on div , scroll using arrow keys. if take @ example , can see want observe if arrow key right/left pressed , if so, jump next image. in firefox , ie, keyup() event being called, , in safari , chrome it's not. i have encountered several strange scrolling , focus behaviours in webkit browsers, don't know why keyup() event not being fired. if have idea, please let me know. just add tabindex attribute div -element , work. kind of hack make otherwise not focusable element focusable, input or button . depending on value given tabindex , behave diffrently: 0 allow focus element keyboard arrows , tab key -1 disable tabbing, still focusable anything greater 0 allow prioratize tab focusing, 1 has highest priority i've updated jsfiddle demo accordingly.

i read this on wikipedia: data uris not separately cached containing documents (e.g. css or html files) data downloaded every time containing documents redownloaded. does mean code downloaded every single time page refreshed or whenever user clicks on navigation link? can cache data-uri's? ps - i'm talking 20 or small png files (mostly silk icons 2 * 16kb files well) data uris nothing more text in form of base64-encoded binary data, that's embedded within html , css files. yes, downloaded part of html , css files every time they're requested, unless files cached. if keep data uris stylesheets , send proper cache headers, caching data: images css shouldn't pose issues.

in delphi xe, i'm trying use getforegroundwindow detect window active before application activated. "activated" means app may have been restored iconic state, or switched via alt+tab, or brought activaton hotkey, etc. the problem available application events (onactivate, onrestore) come late, getforegroundwindow returns own form's handle. main form's events less useful. processing wm_activateapp in main form happens late, too. one way keep checking active window on timer while application not active, seems rather wasteful. better solution subclass tapplication.wndproc , thing before wm_activateapp processed, don't think tapplication can subclassed. is there better way? when application activates, becomes topmost window. iow, jumps top z-order position. with this, previous topmost window demoted "just below new topmost window" position. iow, becomes second in z-order position. calling getnextwindow , passing handle of form , gw...

a little peeking @ disassembly of tree.com (the command shows directory tree given folder) shows functionality lies in ulib.dll , same file system library used chkdsk.exe . which pretty funny, considering enumerating directory tree should pretty straightforward findfirstfile , findnextfile ... so here come 2 questions: why tree.com use ulib.dll (seemingly) trivial? why not use standard traversal methods? is there any documentation whatsoever (official or unofficial) on api of library? thing i've found this api listing, there more? because has version of findfirstfile declared as: void* __stdcall findfirstfilew(class path const *, struct _win32_find_dataw *) why use c api when you've got nice c++ implementation lying around. internal microsoft library, not documented.

as know returns application path? use of it. in many environments application user not allowed read files outside of deployment directory. done security purposes - example if hacks application won't able read passwords file. and in professionally managed environments developers don't have in directory application placed. so if need read file properties, images, certificates, etc. can place in application directory (or .war file) , use getrealpath("") path need load. as alternative can place external files on classpath there issues this. large files app servers try load entire file memory , cache if on classpath.

how can following configuration file read in c++. there support in stl. can't afford use other 3rd party libraries. <?xml version="1.0" encoding="utf-8"?> <appsettings> <add key="filetype" value="doc"/> <add key="filelength" value="102234"/> </appsettings> i not using managed c++. stl has no support parsing xml. if you're determined not use third party library other option write parser hand, seems pretty bad idea. why can't afford use third party libraries?

what reliable way use data uris images? know ie6/7 don't support them, work? i use data uris images default if browser ie6/7 shows image (not data actual image) using javascript include image (not data) in <noscript> . my question is: image fetched in <noscript> if browser supports javascript , data uris? if want go down road (and not bother), could it... // parse user agent , figure out if browser supports data // uris - e.g. `supportdatauri()`. also, store image path // somewhere - i'll assume convenience attribute called `data-image-src` if ( ! supportdatauri()) { var images = document.getelementsbytagname('img'); (var = 0, imageslength = images.length; < imageslength; i++) { var imgsrc = images[i].getattribute('data-image-src'); images[i].src = imgsrc; } }

i scenario there 2 queues. "error" , "myqueue". the messages dumped myqueue , processed there. if fail moved error queue. administration might move message myqueue processing again. my task if scan/peek 2 queue find , count messages has been cycling around more 1 hour. it seems message.senttime message.arrivedtime are both useless, since updated each time message enters queue. on solution place timestamp in body of message, require me open messages determine if message "old". any better alternatives? the problem is not same message cycling round queues. "moving" message deleting original , creating new 1 based on original contents, why can't use sent , arrived times. do moved messages have new unique messageid values each time? if not maybe generate table matching messageid time created. cheers john breakwell

i want connect ftp server directorys "01-26-2011" created on daily basis (no specific pattern, "jan2011-26" possible directory name). inside directory again directories. want write script checks every 10 minutes if new directory created. question is: how can get/read ftp directory creation date? best way (efficient way) check them? if have 1000 directories on ftp root (i mean: jan2011-26, jan2011-25, jan2011-24, jan2011-23, jan2011-22 , on...) bad check every single folder (i don't want that). it's fine if script checks last 5 directories (so jan2011-26, jan2011-25, jan2011-24, jan2011-23, jan2011-22), has check if new directory created in these 5 folders. how can that? thanks! depending on details need, can use ftplib list directories listing. save them list , compare in 10 min 2 sorted lists. can digg deeper , search in ftplib attributes. don't know ftplib, here solution.

i'm starting drupal 7 site , have noticed every page require separate layout. in order style individual node name template mode-nid-page.tpl.php or there more it? i think need add gallery widgets, etc.. think that's separate matter. involve displaying fields in above template? first off: don't think it's idea theme pages based on nid. that aside, here 2 possibilities how can achieve this: theme normal node template, include logic there. example include specific template files based on nid. not clean separation of course, such code should not go templates. cleaner separation attach custom field pages holds template file used themeing. as want create individual styles different nids assume number of not exorbitantly large. in case, create separate content types. each of nids should converted node of content type , of course each content type can have own theme template then. downside of second approach there might work involved if have lot of set...
