i'm doing maintenance on software built predecessor @ company (who has since moved on greener pastures). i'm rolling out new version of software. at company, installation procedure shove /bin/release directory out our automated program updater's magic directory, allowing automatically copy contents of directory on local /program files/ , let magic happen. magic seems happen, there's no big issue, there, although weird me out somewhat, after many years of .msi installers... anyway, rolling out new software went fine on 2 of our file servers, rolling out third , final location went bit differently. the third section of company doesn't use auto-rollout software. use windows' remote desktop connection software run software directly on server. so go along server, check current version working (which is), up, etc. copy exact same software works fine on of our other machines. the new software fails play nice third-party libraries it's using (crystal r

i loading jquery ui as google.load("jqueryui", "1.8.6"); from google cdn , want theme ui darkness associated it. other methods other than <link type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/ui-darkness/jquery-ui.css" /> something like google.load("jqueryui", "1.8.6","{theme: 'ui-darkness'}"); so far google loader doesn't support syntax jqueryui, can check documentation here. http://code.google.com/intl/zh-cn/apis/loader/#googleload i think refer link in tag still best way in case.

in extjs, have simple editorgrid 2 columns, x , y, both of have combo box editor. how is possible make values available in second column's combo box (y) depend on selected value in first column (x)? so, depending on selected in x, values available in y change accordingly. assuming have store backing each combobox, can use store's filter or filterby methods narrow down results of 1 combobox based on other's current selection. can call either filter function on 'select' or 'change' events of combobox. i've used method in past, , worked needs. had around 200 records per combobox, i'm not sure how solution scales if have deal records more that.

i'm calling method i've written in app delegate calls alertview ask user password, use method in applicationwillenterforeground also. so value set in clickedbuttonatindex in app delegate. how determine when value has been set in view controller (where i'm calling method) ? the simplest way delegate viewcontroller. your app delegate have ability access pointers viewcontrollers/navcontrollers have.

i developing web site in using rest web services, there 2 ways of making calls rest web services.. 1. directly through ajax 2. ajax calling servlet in turn make call rest web service personnel experience have observed companies tend follow 2 approach... there reason following approach ?? though can bring same effect following first approach less coding effort... there advantage being achieved second approach missing ?? thanks... the advantage of second case have back-end process on data before hits front-end. can manipulate before goes client, store , use caching , track analytics on data. doing on front-end makes processes hard, though it's possible. also have manipulate data it's read on client. if none of important you, first option way go.

i've been @ little while , mind has gone mush. i'm wondering if can me out here. i'm trying make java web service (using own http server , not tomcat), supports metro , jersey. way client can connect web service anyway want whether soap or rest. i've got metro part down can support doc/lit wsdls , rpc/lit wsdls i've having difficultly understanding jersey part support rest/xml , rest/json also idea there 1 class endpoint methods written in , other classes extend it. has used these 2 combined before? can point me direction of decent article or have example yourself? thanks metro implementaion of jax-ws used wsdl/soap based webservices. jesery implementation of jax-rs used maily restful based webservices. have used both in same project different purposes. can use apache httpclient restful services, jersery provides lot of useful annotations converting json, xml etc. hope helps.

is possible in searchkit (on os x) store document fields in search index, possible in other search libraries? allow displaying fields (author, subject, date, etc) without having read files corresponding underlying documents result of search. do want able read attributes or want able search against them? if want able read them, can add them attributes document via skindexsetdocumentproperties call. retrieve them skindexcopydocumentproperties call. in both cases, properties stored in dictionary. this assumes know how read properties file , you're not blindly relying on search kit / spotlight importers. if want able search against properties, you're going have search index properties want search.

here code- $things = mysql_real_escape_string(implode(',', $_post['things']),$link); $q = "insert tblslider(src) values ('".$things."')"; print_r($q); $result = $mysqli->query($q) or die(mysqli_error($mysqli)); but query getting generated insert tblslider(src) values ('4368122.jpg,5440051.jpg,1047428.jpg') should insert tblslider(src) values ('4368122.jpg'),('5440051.jpg'),('1047428.jpg') thats why taking 1 record not three. you do: $things = array_map('mysql_real_escape_string', $_post['things']); $q = "insert tblslider(src) values ('". implode("'),('", $things)."')"; it generates (with test data): insert tblslider(src) values ('a.jpg'),('b.jpg'),('c.jpg') i forgot: use functions mysql_real_escape_string on real data, not sql string. in example apply function on concatenated data.

i try write code finding status of printer print crystal reports in pdf format. have following doughts: how can fire code after click print button in crystal report? there events(lick click) check printer staus? what properties change when printer in different modes lid open, no paper, lidopen , no paper, swtch off, switch on, warmup ect.? numeric values returns? , there changes in return values different catagery printers(hp laser printes, canon ect..)? how can display message "success" after successful printing of report? pls, clarify one. you can use system.management win32_printer class query printer information. there win32_printjob , enumerate determine when given job completes. status property may give additional granularity on printer status. can monitor creation , deletion of these objects - give new , completed job info. other printer classes listed here .

i'm having issue lucene's term [boosting][1] query syntax, in ruby on rails via sunspot_rails gem. whereby can specify weight of specific term during query, , not related weighting of particular field. the html query generated sunspot uses qf parameter specify fields searched configured, , q parameter query itself. when caret added search term specify boost (i.e. q=searchterm^5) returns no results, though results returned without boost term. if, on other hand, create http query manually , manually specify field search (q=title_texts:searchterm^5), results returned , scores seem affected boost. in short, appears though query term boosting doesn't work in conjunction fields specified qf. my application calls search across several fields, using respective boosts associated fields, conditionally in turn boosting on individual terms of query. any insight?

i know shared hostings don't allow svn installation. i got question whats best way copy website repository shared hosting. now: my repository on other vps. i checkout computer , copy shared hosting. how can copy data repo hosting 1 step? if have ssh access target webserver , give rsync , scp look: http://en.wikipedia.org/wiki/rsync http://en.wikipedia.org/wiki/secure_copy i not advise installing subversion server (either svnserve or via apache) on production web server. nor advise copying, or checking out, working copy on web server. many security issues. basically, want generate local copy of site in staging area, , rsync (or scp) production server. you can manually, or better yet, make small "deploy site" shell script will: svn export version/tag want deploy in clean local folder. rsync folder production server. hope helps... luck! :)

what difference between char , nchar , ntext , nvarchar , text , varchar in sql? is there application case each of these types, or of them deprecated? text , ntext deprecated, lets omit them moment. left, there 3 dimensions: unicode (ucs-2) vs. non-unicode: n in front of name denotes unicode fixed length vs. variable length: var denotes variable, otherwise fixed in-row vs. blob: (max) length denotes blob, otherwise in-row value so this, can read type's meaning: char(10) : in-row fixed length non-unicode of size 10 nvarchar(256) : in-row variable length unicode of size up-to 256 varchar(max) : blob variable length non-unicode the deprecated types text , ntext correspond new types varchar(max) , nvarchar(max) respectively. when go details, meaning of in-row vs. blob blurs small lengths engine may optimize storage , pull blob in-row or push in-row value 'small blob' allocation unit, implementation detail. see table , index organiz

i have pretty basic question storing data , memory footprint. i have list<t> stores base objects need. type t has int id define it, along other fields. i have dictionary. if create dictionary<t, int> , t object value, memory allocation higher if create dictionary<int, int> , ie copy of t object stored, or refence t stored again? thanks that depends on t is. if t reference type (that is, class ), reference stored in dictionary. if t value type (a struct ), copy stored.

i'm making banking model, , account class has accountnumber field. account number should never change, cannot set field final because prevent constructor setting it. if it's not possible this, doesn't matter. it's cs assignment want make sure i'm doing best way can. would best implementation make field , setter method private? the constructor can set if marked final e.g. following legal: public class bankaccount { private final int accountnumber; public bankaccount(int accountnumber) { this.accountnumber = accountnumber; } } in fact if field marked final not initialised in declaration must set in constructors. if not put public setter on class account number can't changed outside class marking final prevent (accidentally) being changed methods inside class.

(btw, actionscript = joke language) when scrollbar added textarea, dispatches event added. can catch scrollbar this: textarea.addeventlistener(event.added, ontextareachildadded); private function ontextareachildadded(event:event):void { if (event.target uiscrollbar) { //you got var scrollbar:uiscrollbar = event.target uiscrollbar; } } event scrollbar fired once. there many other stuff adds textarea, type check needed. know ya jokes , cool ^_^ edit: wrong... real solution seems textarea.verticalscrollbar.

i'm working several functions need pass variable , forth. should use global variable or method instead? appreciate example or 2 on how implement it. thanks, elliot bonneville psuedocode of functions: function getxml() {//this function reads in xml file. //preferably generate or set object hold xml data. } function usexmldata() { //i use xml data here. } function usexmldatahereaswell() { //and here well. } the best solution you're trying wrap data object , make functions methods on object: function myxmlclass() { this.data = null; } myxmlclass.prototype = { getxml: function() { this.data = ...; }, usexmldata: function() { // use this.data }, /* etc. */ }; and can use this: var x = new myxmlclass(); x.getxml(); x.usexmldata(); ...

i have form accepts user’s input. is, base on user input, i’d retrieve data , display user. so far, have implemented hook_menu , registered respective url of form, , implemented submit function referred “#submit” attribute of submit button. i’ve implemented data retrieval code , works great. here’s problem – don’t know how display retrieved data. i’ve tried several approaches in attempt find solution. first, theme function, hoping printing return value of display data. second, setting “#action” element of form array newly registered url, thought using same url form cause drupal return form instead , not data. so, creates static variable , stores retrieved data in it;this done inside submit function way. when checked variable inside menu callback, variable not set. to summarize problem, form has different access url form submit, such as form url – http://....?q=mymodule/form submit url (value of ”#action”) – http://....?q=mymodule/execute , , data i’ve set inside submit

i have class called clientchat basic network stuff. have several other classes linked different window forms. in first form have variable referenced chat class so: clientchat cc = new clientchat(); everything works okay their, class has been initialized , in motion. after first forms done performing it's duty bring second form that's linked new class file. now question is, how can reference what's going on in clientchat class without setting new instance of class? need pass data form networkstream , if create new instance of class wouldn't require new connection server , require start on since it's "new"? i'm bit confused , great, thanks. c# on .net4.0 you create instance of clientchat in beginning of program , then, pass reference classes need it.

i have googled , read hours , can't find deals specific scenario... i want use interfaces in wcf service contracts loosely couple service classes used on each end of wire. enable have low-level assembly contains service , data contracts (just interfaces) can hand consultant. on end of wire can instantiate data classes implement our data contract interface, send on wire us, , our wcf service translate/cast/whatever incoming data our version of data class implements same interface. here's example. idatacontract contains bare information want transmit on wire. endpoints , other wcf-specific config default stuff (my problems may lie in that, can include more of if that's need change things). edit : i've included more of code , renamed couple classes less confusing. name & namespace additions datacontractattributes, 2 sections in config files new additions based on information this blog post . if switch abstract base class instead of interface, it works . how

how go grouping following? people.groupby(p=>p.addresses.getfirstordefault().state); without failing on people don't have address? can done in 1 statement? if not, have first distinct() list of various addresses members? how? (actually -- if possible -- great learn how b :-) ) i havn't seen it, there equivalent getfirstornew() can used instantiate , return non-null? thank much! it can done in 1 statement, yes: // set whatever need address dummyaddress = new address { state = "" }; people.groupby(p => (p.addresses.getfirstordefault() ?? dummyaddress).state); alternatively, might want write helper method: public string getstate(address address) { return address == null ? null : address.state; } then can use: people.groupby(p => getstate(p.addresses.getfirstordefault()));

why overloaded operator= mandated member function ($13.5.3), not compound assignment operator e.g. operator+= ($13.5.2)? overlooking here? a copy assignment operator= , member, provided compiler if user doesn't define one. believe simplicity , avoid unexpected ambiguities made requirement operator= can't defined free function. conversion operators take care of case when want assign user-defined type built-in type.

in project, calling webservice http request. api key there in http parameter. in j2me devices before connecting internet showing url , asking permission user.here user can see api key. and don't want store api key in application also.because using decompiler can api key applciation. so question store api key , how use calling web services? if api key required use webservice, must store somewhere in app...by way, can store in kind of encrypted way, simple decompile not reveal it. if user should enter api key, can store in standard rms store outside of app, again maybe encrypted. an url issue, use http post request instead of http get, , send key in post data.

i'm experimenting seam interceptors. i have custom annotation defined as: @target(type) @retention(runtime) @interceptors(someinterceptor.class) public @interface myinterceptannotation { } and have superclass annotated @myinterceptannotation @myinterceptannotation myabstractsuperclass{...} is possible have subclasses derived myabstractsuperclass intercepted?? best regards no, suppose. can try out. however, can done on package level, using package-info.java . so, classes belong particular package intercepted. below, package-info.java @myinterceptannotation package my.package.name; import my.annotation.package.name.myinterceptannotation; in order force subclasses define annotation, @ this thread . just came across related thread , spring . wonder if have similar way in seam . can try find out.

my question using fulltext.as know queries begin % never use index : select * customer name %username% if use fulltext query can ı take better performance? can sql server use fulltext index advantages queries %username%? short answer there no efficient way perform infix searches in sql server, neither using like on indexed column, or fulltext index. long answer in general case, there no fulltext equivalent operator. while works on string of characters , can perform arbitrary wildcard matches against inside target, design fulltext operates upon whole words/terms only. (this slight simplification purpose of answer.) sql server fulltext support subset of prefix term operator. docs ( http://msdn.microsoft.com/en-us/library/ms187787.aspx ): select name production.product contains(name, ' "chain*" '); would return products named chainsaw, chainmail, etc. functionally, doesn't gain on standard like operator ( like 'chain%' ), , l

i'm trying intercept spring controller calls annotated, similar to: @requestmapping("/my/page") @accessrestriction(module = module.audit, action = auditactions.log) public modelandview mypage() { // pls type teh codez } at point want access both values of @accessrestriction method, httpservletrequest object check if values match restrictions , httpservletresponse object in order send redirect , if applicable. being able throw exception might suitable well. i've looked interceptors don't offer access method, handler. options of achieving this? my suggestion decouple 2 concerns, 1 check annotation , throw exception, catch exception , translate redirect. the first concern done using auto-proxy facility , apply aop-style interceptor invocations on controller objects. check annotation, validate invocation, , throw custom runtimeexception conditions violated. you have custom handlerinterceptor checked exception in aftercompletion method

i want replace every second white space " , " using preg_replace . , input string this: $string = 'a b c d e f g h i'; should result in output this: a b,c d,e f,g h,i thanks you can use combination of explode , array_chunk , array_map , implode : $words = explode(' ', $string); $chunks = array_chunk($words, 2); $chunks = array_map(function($arr) { return implode(' ', $arr); }, $chunks); $str = implode(',', $chunks); but assumes each word separated single space. another , easier solution using preg_replace this: preg_replace('/(\s+\s+\s+)\s/', '$1,', $string) the pattern (\s+\s+\s+)\s matches sequence of 1 or more non-whitespace characters ( \s+ ), followed 1 or more whitespace characters ( \s+ ), followed 1 or more non-whitespace characters, followed 1 whitespace character, , replaces last whitespace comma. leading whitespace ignored. so matches in case: a b c d e f g h \__/\__/\__/\__/ th
