today discovered had assumed vb.net many years not true (worrying!). assumed variable declared within loop had lifetime of iteration declared in, in fact seems has lifetime of whole procedure. for example: integer = 0 1 dim var1 boolean console.writeline(var1.tostring()) var1 = true console.writeline(var1.tostring()) next console.readkey() i had assumed output of false, true, false, true instead false, true, true, true. in c# equivalent code not compile compile time error of error "use of unassigned local variable 'var1'". i realise there many ways fix , best practice declare variable outside of loop , reset @ beginning of every loop through. i find behaviour counter-intuitive me @ least compile time warning in vb.net when/if this.

why php allow nesting functions? <?php function foo() { function bar() { return "bar"; } return "foo"; } print foo(); print bar(); .. valid php. but: why nesting needed ever? and if so, why can call bar anywhere (and not, e.g. withing foo(), or trough foo.bar() or such). i ran today, because forgot closing bracket somewhere, , had 1 many further down. code valid , no errors thrown; started acting weird. functions not being declared, callbacks going berserk , on. feature, , if so, purpose? or idiosyncrasy? answer : commentor points out duplicate of what php nested functions for . note order important here; cannot call bar() before calling foo() in example. logic here appears execution of foo() defines bar() , puts in global scope, it's not defined prior execution of foo(), because of scoping. the use here primitive form of function overloading; can have bar() function perform different operations depending u...

i installed visual studio 2010 .net framework 4.0 , c# , can't find under system.management namespace except system.management.instrumentation . online documentation @ msdn wmi keeps telling me have use classes such system.management.managementobjectsearcher or system.management.managementscope don't see classes. what happened classes , how can access them? you need add reference system.management.dll project. you can see system.management.instrumentation without adding reference system.management.dll because included in different library ( system.core.dll , included reference automatically), cannot access other types contained namespace without explicitly adding reference system.management.dll library.

i have question regarding css in firefox. if set width of floated div - lets 200px - setting padding-left 10px in firefox add 10px width. in ie not case. what can prevent firefox adding width div? it's not firefox that's problem, it's ie. ie not perform standards, there few tricks pain in ass: http://en.wikipedia.org/wiki/internet_explorer_box_model_bug the easiest way include valid strict doctype tag: <!doctype html public "-//w3c//dtd xhtml 1.0 strict//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-strict.dtd"> then rewrite css standards-compliant box model more doctypes here

while difftime class pretty straight forward use when want obtain yearly or daily differences between dates. monthly differences weren't straight forward me. since r standard arithmetic allows substraction of date objects looping through vector possible, here´s solution avoids looping: # generate reproducible example x<-seq(as.date("2010-11-15"),as.date("2011-05-20"),"months") y<-seq(as.date("2010-04-15"),as.date("2012-05-20"),"months") z<-seq(as.date("2012-08-15"),as.date("2013-05-20"),"months") d <- c(z,x,y) # function – suggestions welcome! getperiods <- function(datevector){ x <- floor((as.numeric(datevector)-as.numeric(min(datevector))) / 30) +1 return(x) } # returns vector of monthly ordered periods. is there better, more native way it? example can use seq() in combination lenght() somehow? not able because seq´s "to" argument not allow vectors. fee...

is there reliably way determine last user name login system? i've looked @ lsaenumeratelogonsessions() , lsagetlogonsessiondata() require elevation on vista , later (which i'm keen avoid). wmi has same problem (presumably it's calling lsa behind scenes). i've looked @ "software\microsoft\windows\currentversion\authentication\logonui\lastloggedonuser" in hklm, in testing that's unreliable , doesn't updated. i'm interested in console logons, rather fast user switching or ts logons. i've read various articles, have yet come solution. you might able use audit logon events - requires service have user access right see security log, not full administrator. eventid 528 indicates logged on, you'd have find recent instance of this.

i building mvc app reporting. have page has form on contains multiple dropdownlist choose criteria report. have input button create report. button call new view same controller. new view gets values page criteria chosen parameters , uses populate it's own view model. working fine. i open reports in new window. when @ controller, of parameters supposed coming selection page null. assume have pass these in via querystring picked controller. there way can values of dropdownlists within viewpage construct querystring? is way accomplish trying do? better of using actionlink instead of input button? make difference? i hope makes sense. thoughts. just set target attribute on form _blank , should open request in new page/tab depending on browser being used. <% using (html.beginform(myaction, mycontroller, formmethod.post, new { target = "_blank" }) { %> <%-- ... --%> <% } %>

i using own iterable structures - various binarytrees. can marshal them? it's quite easy marshal f.e. java.util.list implementations, in case, it's absolutely unacceptable. need use own structures, no internal containers whatsoever - memory chains (root.leftson.rightson etc.) in other words, possible marshall structure like: class binarytree<t> implements iterable<t> ? edit: structure supposed (for binarytree<person> ): <persons> <person> <name>john</name> <surname>black</name> </person> <person> <name>joe</name> <surname>blue</name> </person> </persons> so when add annotation structure like: @xmlelement private binarytree<person> persons = new binarytree<person>(); public binarytree<person> getpersons() { return persons; } ,it creates empty element <persons /> . tried @xmlelementwrapper annotations, won't take c...

there program crawls , index documents stored in sharepoint. need run every period of time. of suggestions had: transfering application windows service , schedualing run every period. having program trigger application every period of time. which of 2 ways consider more efficient. other suggestions pretty welcome. thank you. if program simple enough, use windows' task scheduler run periodically (your option #2). there no need write windows service this.

i error message "can't start up: not enough memory" when run code "java -xmx30g examplecode". this error not happen when don't specify java virtual machine size. have clue why error message when set virtual machine size? if -xmx smaller 1g runs, if not got mentioned error message. thanks in advance help! and yes, there enough ram :) (72g available). btw, javahome /opt/jre1.6.0_20 the os can impose limit on how large process can be. example, in 32-bit windows, limit ~2gb, if machine has 4gb ram. check or os settings, , sure running jvm allowed (i.e. if you're on 64-bit system supports size process, sure run 64-bit jvm)

i've 2 controls 1 on top of another: border on slider. on border user can mark segment appear in different color on slider. because border written after slider in xaml, appear on top of slider. , that's ok. problem is, thumb of slider appears under border. how can set thumb element (belong slider control , inside it) appear on top of all, , border appear on top of slider? tried use zindex without success. idea? in css: make sure elements positioned absolutely or relatively. z-index doesn't have play in layering unless elements positioned absolutely or relatively. should able set 1 with: z-index: 1; and other with: z-index: 2; and desired result. in wpf: use syntax specified here here's example: make sure both of elements in same parent, otherwise displayed in order in loaded.

this simple, wanted feedback, guess. long story short super novice programming, , i've (about 6 months ago) started doing game programming, , it's going fine. can work , that, that's not question. instead, has passing objects. pretty pass same object or variable several times through game loop. so, cameras, camera used draw objects. first camera passed container object (like drawing frames of animation, animation object contains frames), passes individual object, draws. now, passes camera maybe 3 times max, it's no worry, yet. what more concerning similar multiple-passing array of tiles makes map. first array passed 'update' function of player or enemy, passed individual move , input functions check collisions, , in functions it's passed collision detection function. anyway, pretty happens object (in case, array of 100~1000 tiles) gets passed 4-5 times per game loop. wondering if should use constant reference instead of passing on , on again. pre...
