i'm using 2 components essential objects namely downloader , file explorer. doesn't matter. the file explore (similar window's file explorer) has client api can fire event when select file using it. event fire uses javascript function: function file_selected(fe) { var filename = fe.getselectedfile(); foo(filename); } the downloader has property want update using filename. how can client side? in code-behind it's easy: downloader.filepath = ""; event fires client side. heard ajax have no experience it, i'm struggling find solution. this depends on control , not general question asp.net controls. there documentation if there api. ajax nothing more asynchronous javascript , xml, doesn't feel relevant problem.

from i've seen , read, if wants reverse-engineer software or decompile it, proguard not going stop them. @ least modest deterrent? i'm not sure if it's worth hassle of translating stack traces later on. i recommend proguard. without obfuscation (which can shorten names used in constant pool) can remove "dead code" (unused methods) of used libraries, etc. (it can used conveniently merge together). it takes little bit of fiddling "get correct", esp. if there dynamically loaded classes -- recommended. actual benefit space-saving, however, "depends" on can eliminated , goes more external libraries. now, obfuscation -- as obfuscator: makes "decompiling" code things with meaningful names impossible. obfuscation won't save super-secret-algorithm or hide private keys, though: if jvm (or dalvik after transformation) must understand it, can decompiler , really wants access can. code lifted in bytecode-form , used via. r...

to understanding, socket connection timeout controlled tcp transport, uses retransmission timeouts (rtos). if the ack not come before timer expires, connect request (sync) retransmitted, , rto doubled. so functionality of connection timeout in java socket when call socket.connect(endpoint, connecttimeout) so functionality of connection timeout in java socket when call socket.connect(endpoint, connecttimeout) it sets overall timeout connection have been established; i.e. says how long application prepared wait of packet-level timeouts, retransmissions, etc succeed (or not) before giving up.

an api http://www.yourwebservice.com/pip.jsp?request=aaa&param=2 lets consider above api gives json value. use below coding json: nsurl *url =[nsurl urlwithstring:@"http://www.yourwebservice.com/pip.jsp?request=aaa&param=2"]; nsstring *resultedstring=[[nsstring alloc] initwithcontentsofurl:url]; it returns json resultedstring variable. small amount of data. if api has large amount of data in 100's of kb's whether coding work fine, or crash? many apis limit responses - example, twitter api not return more 1500 results. http://dev.twitter.com/doc/get/search

setup: we have .net application distributed on 6 local servers each local database(oracle), 1 main server , 1 load balance machine. requests come load balancer redirects incoming requests 1 of 6 local servers. in time intervals data gathered in main server , redistributed 6 local servers able make decisions complete data. each local server has cache component caches incoming requests based on different parameters (location, incoming parameters, etc). each request local server decides whether go database (oracle) or response cache. in both cases local server has goto database 1 insert , 1 update per request. problem: on peak day each local server receives 2000 requests per second , system starts slowing down (cpu: 90% ). trying increase capacity before adding local server mix. after running benchmarks bottleneck is, seems inevitable 1 insert , 1 update per request database. tried methods to able decrease frequency have created windows service sits between db , .net appli...

i'm looking ways automate tasks in eclipse. for instance, let's have couple of ant files i'll want run couple of times per hour. being able assign hot key each 1 of them, run them without having click, bring context menu , click again bring joy life. other example build/run configurations. have couple of them on project , i'd love have way of running each 1 of them different hot key configuration. moreover, nature of project i'm working on involves lot of experimentation , trying, having click , use mouse lot driving me insane. there other similar things automated (for example, each time commit i'd run command on project's folder, etc). is there tool eclipse(or outside it) that'll somehow allow me automate these kinds of tasks? vim eclipse me anyhow? after years coding feel have hit stone wall. came conclusion losing way time mouse. yes, know lot of eclipse actions have correspondent hot keys, lot of others don't. want ultimate solutio...

is possible substitute foreach loop lambda expression in linq ( .select) )? list<int> l = {1, 2, 3, 4, 5}; foreach (int in l) console.writeline(i); to: list<int> l = {1, 2, 3, 4, 5}; l.select(/* print console */); there no linq equivalent of foreach, although easy implement 1 yourself. eric lippert gives description here of why not implemented in linq itself. however, if collection list (which appears in example), can use list.foreach : mylist.foreach(item => console.writeline(item));

i need restart application using service running on system account. problem application started under system account. various reasons beyond control restart system bit complicated result of complicatedness(c) i'm sure there must @ least 1 stage possible specify account app run on. the service calls bounce.bat contains following: @echo off cscript "c:\program files\myapp\bounce.vbs" the relevant section of bounce.vbs is: set oprocess = owmiservice.get("win32_process") set oprogram = oprocess.methods_("create").inparameters.spawninstance_ oprogram.commandline = spath & sexe set sshell = owmiservice.execmethod("win32_process", "create", oprogram) if there no clever suggestions i'll try this approach, i'm sure there must cleaner way.
