on server, under advanced tcp/ip settings have 2 ip addresses added. question is, how can specify want listen first or second ip? there way obtain ip addresses on machine via .net , select 1 listen to? any appreciated. hope question clear. thanks. the tcplistener in system.net.sockets accepts ip , port on construction: int32 port = 13000; ipaddress localaddr = ipaddress.parse("127.0.0.1"); // tcplistener server = new tcplistener(port); server = new tcplistener(localaddr, port); the full msdn article here , @ tcpclient

how solve following error? cs0234: type or namespace name 'helpers' not exist in namespace 'nerddinner' (are missing assembly reference?) if error occurring within class: add using nerddiners.helpers; using statements in class. as short cut, can place cursor on relevant part of code , press ctrl + . , visual studio add you. if error occurring within view: add following top of view (under inherits definition) <%@ import namespace="nerddinner.helpers" %> or can add namespaces section of projects web.config <namespaces> ... <add namespace="nerddinner.helpers" /> if error occurring within test class need add project reference main nerddinners project within add references option of test project.

i tried search both here , on jetbranis.net did not found answer. i have created project ( p ) using maven have modules ( a ,*b*). module a dependant on module b , module b dependent on libraries r . when open p using intelij idea 10.0.1 works smoothly. problem have dependency handling. the dependencies imported transitively. both a ,*b* dependent on libraries r . expect b dependent on r , expect r exported , a dependent on b . i found old posts on jetbrains seam related, seams have opposite problem http://devnet.jetbrains.net/thread/286098 . can advise me please? did missed configuration option? this how maven's dependencies work; each module (aka maven project) has isolated classpath. dependencies, imported idea, not 'exported' prevent interference between transitive dependencies.

according documentation simple html dom parser (under tab “how modify html elements”), code finds first instance of <div class="hello"> : $html = str_get_html('<div class="hello">hello</div><div class="world">world</div>'); $html->find('div[class=hello]', 0)->innertext = 'foo'; echo $html; // output: <div class="hello">foo</div><div class="world">world</div> what if want insert 'foo' last instance of <div class="hello"> , assuming html code has lot of instances of <div class="hello"> . what should replace 0 ? well, since // find anchors, returns array of element objects $ret = $html->find('whatever'); returns array holding <whatever> elements, can fetch last element php's regular array functions, e.g. end $last = end($ret); if simplehtmldom implements css3 selec...

there command line feature i've been wanting long time, , i've thought how best realize it, got nothing... so i'd have when start typing filename , hit tab,for example: # git add foo<tab> i'd run find . -name "*$1*" , autocomplete complete path matched file command line. what have far: i know i'll have write function call app parameters want, example git add . after needs catch tab-keystroke event , find mentioned above, , display results if many, or fill in result if one. what haven't been able figure out: how catch tab key event within function within function. so in pseudocode: gadd() {git add autocomplete_file_search($1)} autocomplete_file_search(keyword) { if( tab-key-pressed ){ files = find . -name "*$1*"; if( filecount > 1 ) { show list; } if( files == 1 ) { return files } } } any ideas? thanks. you should take @ introduction bash completion . briefly, b...

i'm using php, , need parse date string formatted dd/mm/yyyy , store in mysql. how can convert string datetime variable in mysql table? probably best way using this: http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_str-to-date select str_to_date('04/31/2004', '%m/%d/%y'); -> '2004-04-31' or equivalent php functions like: http://www.php.net/manual/en/function.date-parse-from-format.php (from php 5.3) a generic php function like function convertdate($datestring) { return date('y-m-d h:i:s',strtotime(str_replace('/','-',$datestring))); } or function convertdate($datestring) { $a = explode($datestring('/')); return "{$a[2]}-{$a[1]}-{$a[0]} 00:00:00"; }

when running php scripts on iseries, though set memory limit -1 in php.ini... php says runs out of memory around 256mb. i'm curious if there way allocate more memory job on iseries allow php allocate more memory. finally figured out! on iseries apache configuration must set following environment variable in httpd.conf file: setenv="ldr_cntrl=maxdata=0x80000000" this allow access 2.25gb of memory in 1 php script via web server instead of 256mb (in case using zendserver , had edit config file fastcgi.conf) ref : zend forum post ibm reference

given array a of n integers draw n discs in 2d plane, such i-th disc has center in (0,i) , radius a[i] . k-th disc , j-th disc intersect, if k-th , j-th discs have @ least 1 common point. write function int number_of_disc_intersections(int[] a); which given array a describing n discs explained above, returns number of pairs of intersecting discs. example, given n=6 , a[0] = 1 a[1] = 5 a[2] = 2 a[3] = 1 a[4] = 4 a[5] = 0 there 11 pairs of intersecting discs: 0th , 1st 0th , 2nd 0th , 4th 1st , 2nd 1st , 3rd 1st , 4th 1st , 5th 2nd , 3rd 2nd , 4th 3rd , 4th 4th , 5th so function should return 11. function should return -1 if number of intersecting pairs exceeds 10,000,000. function may assume n not exceed 10,000,000. so want find number of intersections of intervals [i-a[i], i+a[i]] . maintain sorted array (call x) containing i-a[i] (also have space has value i+a[i] in there). now walk array x, starting @ leftmost interval (i.e smallest i-a[i] )....

i'm using rails 3 paperclip , allow users upload attachments attachment model. if file image, app generates image previews. if file not, uploads file (no image previews). now display list of attachments in db. use attachment.attachment(:large) , works fine image attachments, errors (obviously) non-image attachments. what's way check if it's image attachment or not? if not, i'd display standard static image. suggestions? thanks this did in view: <% if !(@attachment.attachment.content_type =~ /^image/).nil? %> <%= image_tag @attachment.attachment.url(:small) %> <%end%> this assumes model attachment, , file, called attachment. so like: <% if !(@attachment.attachment.content_type =~ /^image/).nil? %> <%= image_tag @attachment.attachment.url(:small) %> <%else%> <%= image_tag "/path/to/image/default.png" %> <%end%>

this question extremely basic , apologize if answer should staring me in face. so: have uitableview , viewcontroller. i'm updating information coredata in uitableview's .m file. in order need text in text field in other viewcontroller. so being rather inexperienced, tried: [entity setname:[nsstring stringwithformat:@"%@", viewcontroller.entitynameinputfield.text]]; i've renamed few things clarity. entity entity (no kidding), attribute i'm setting called name, viewcontroller textfield , text field called entitynameinputfield. i'm lot more interested in why sort of thing doesn't work solution problem might be. why can't text text field in way? i suppose word differently: if i'm in class , want access value of say, nsstring in class b, why can't use classa.thestring or [classa thestring] .... i've managed understand, i'm sending these objects getter methods , can't seem see why doesn't work... any appreciate...
