hello everybody. i know how download , save file hard drive, zip file http server using system.net.socket.sockets class. i know there allot easier ways download file .net, know how with sockets , if possible of course although i'm pretty sure is. i've tried few things, nothing worked once don't have background experience sockets. your satisfying curiosity appreciated. question ask. thank you. note : the file standard zip file, way work file type. the file size different every day. the file downloaded every minute, caching of such file must disabled accurate , update file version server. file url sample: www.somewhere.com/files/feed/list.zip you directly .net socket, require parsing , understanding http request. the standard way use higher level system.net classes. example, can done in 2 lines of code via webclient.downloadfile - why make life more difficult yourself? if must raw sockets, take lot of work. @ it's core, can conne...

the function getfileinformationbyhandle gives structure values nfileindexhigh , nfileindexlow comprise of fileindex . what number? same usn? is there way fileindex of file without opening it (any other method except getfileinformationbyhandle)? you can use zwquerydirectoryfile fileobjectidinformation , fileidbothdirectoryinformation , fileidfulldirectoryinformation query object id information files in directory. in case have open directory having file , not file itself. can useful example if file opened exclusive access or of cause if has no permission open file , not have or want not use backup privilege. updated : following test example #include <windows.h> #include <stdio.h> #include <tchar.h> typedef long ntstatus; #define nt_success(status) (((ntstatus)(status)) >= 0) #define nt_status(x)((ntstatus) { x }) #define status_success ((ntstatus)0x00000000l) #define status_no_more_files ((ntstatus)0x80000006l) #define statu...

i have give functionality select photos user. have used this: ipc.sourcetype = uiimagepickercontrollersourcetypephotolibrary; now have restrict user select photos , want videos not displayed on list. or somehow user should not select video @ all. how achieve that? basically you're trying set "media types". , luckily imagepicker has property called "mediatypes". :) receives array of media types show selection. even luckily-er default behaviour of imagepicker show image types. but if want make sure can this: [imagepicker setmediatypes: [nsarray arraywithobject:kuttypeimage]]; and don't forget add @ top of file... :) #import <mobilecoreservices/utcoretypes.h> but really, think can trust apple when it's they're default behavior... :)

it appears in c# 4.0, variance specifiers applicable interface types. so let's have viewmodel / editmodel classes , simple hierarchy of models. class myeditmodel<t> t : base { ... } class derived1 : base { ... } class derived2 : base { ... } i have partial view accepts myeditmodel of type (so long it's derived base) , 1 accepts instances of derived1. how render both on same page? the partial view accepts myeditmodel shared between editor derived1 , editor derived2. the has if view accept view model of base. oo perspective myeditmodel , derived1 share base common base class - don't share else - there no other relationship. hence, if you're trying use same have derive base. presumably properties on base ones have in common. edit : mis-interpreted original question. based on literal text of question, thought passing derived1 base on comment below passing myeditmodel<derived1> . you're seeking: inherits="system.web.mvc.viewpag...

i using ngnix infront of 4 instances of node.js apps running on 1 machine (quad core) can ngnix experts give me advice on how configure out of web app. i using connect/express frameworks on node , think allow smart caching etc, but not sure bits let ngnix , bits let frameworks handle. guidance on getting out of setup great help, thanks. you need take account 1 node instance use several threads, , keep @ least 1 thread occupied i/o. run 4 instances on quad core, means 4 instances produce blocking threads, meaning have @ least 4 blocking threads (if have busy server) meaning @ point block activity short periods. i suggest not starting more (number of cores)-1 instances of node, half sure @ least keeps moving. i assume there 1 blocking thread per node instance, wrong. there more. point remains same. more "free" threads start, more "blocking" threads created well.

ok have php variable $question looks this: $question['3']['type'] = 'checkbox'; $question['3']['desc'] = 'checkbox question'; $question['3']['deft'] = '1'; $question['3']['opts'] = 'check test 1'; $question['3']['opts'] = 'check test 2'; what want have question on survey desc question, , opts multiple answers. i have statement: if ($type == "checkbox") { if (strtolower($deft) == 'y') { $box_value = "1"; $checked = ' checked'; } else { $box_value = "0"; $checked = ''; } print "<input type=\"checkbox\" name=\"$key\" value=\"$box_value\"$checked>\n<br>"; } it works doesn't allow me include question (only answers). i want this: if ($type == "checkbox") { print "...
