i have litle problem chart binding. possible have dynamic number of series wpf toolkit line chart? i found many examples how manualy. for example if have like: <chartingtoolkit:chart grid.columnspan="4" grid.row="3" horizontalalignment="stretch" verticalalignment="stretch" name="chart_distribution" title="chart title"> and model like: public class test : baseviewmodel { private readonly observablecollection<lineseries> _lineseries = new observablecollection<lineseries>(); public observablecollection<lineseries> lineseries { { return _lineseries; } } private void test() { var collection = new observablecollection<requestsinprocess>(); var collection2 = new observablecollection<requestsinprocess>(); collection.add(new requestsinprocess(0, 4)); collection.add(

i’d execute more 1 statement in stassertxx family of macros, possible? like: stasserttrue([foo dosomething] && [bardosomethingelse], @"should…"); the code above works methods return booleans, i’d similar void return types: stassertnothrow({ [foo dosomething]; [bar dosomethingelse]; }, @"should…"); of course, here preprocessor complains. since valid c code valid objective-c; can use , operator c single argument, long use in parenthesis. like this: nsassertnothrow(([foo dosomething], [bar dosomethingelse]), @"whatever"); the , operator lets composite several expressions single statement returning value of last expression. i advise strongly against using in stassert… statements since loose important information tests failed.

i have different build targets periodic builds , triggered polling scm. more specific: idea nightly builds should call 'mvn verify' includes integration tests, while normal build calls 'mvn test' executes unit tests. any ideas how can achieved using hudson? cheers chris you create 2 jobs - 1 scheduled , other polled. in scheduled can specify different maven goal polled.

if place file called liba.jar in classpath folder, , rename old 1 to: liba.jar.old will classloader load classes? i'm using weblogic on solaris 8. thank you! udo no. if you're using java 5 or earlier, must explicitly name classes , jar files loaded. obviously, since old one, liba.jar.old isn't named, won't loaded. it's bit of different story if you're using java 6, since concept of wildcard matching exists there. still, non jar files won't loaded. info taken official site . quote: class path entries can contain basename wildcard character *, considered equivalent specifying list of files in directory extension .jar or .jar. example, class path entry foo/* specifies jar files in directory named foo. a classpath entry consisting of * expands list of jar files in current directory. class path entry contains * not match class files. match both classes , jar files in single directory foo, use ei

based on previous question how id of calling component in getter method? , here's idea want ask opinion : there lots of duplicated code across jsf pages such these examples (notice repeating size , maxlength attribute) across components : <h:inputtext label="#{msgs.userid}" id="userid" value="#{userbean.userid}" required="true" size="#{variableconfigbean.getsize(component.id)}" maxlength="#{variableconfigbean.getmaxlength(component.id)}" /> <h:inputsecret label="#{msgs.password}" id="password" value="#{userbean.password}" required="true" size="#{variableconfigbean.getsize(component.id)}" maxlength="#{variableconfigbean.getmaxlength(component.id)}" /> im thinking of : using composite component input text tag, hardcoding size , maxlength in implementation section of composite component, so dont have duplicate thes

i once trying adding 2 values same key, didn't work. overrode old value. isn't possible add more 1 value same key, , when retrieving key, linked list can iterate different values? not unless store array value. hashtables in php map key one value. value array, you have build array yourself. might consider creating class you.

i'm using delphi 2007 , wonder how following problem can solved: i have translate acomp.caption example, string want assign caption, depends on data (for example date or number, gets formatted ). therefore have save data , string in new variable every translation, annoying. what want that: // add string , data internal list of translator // , return dynamicstring, represents translated value acomp.caption := t.newtranslatedstring("hello %s, cheese?", user) (note acomp.caption ("hello %s..") can changed in different methods) when switching language, call t.translateagain() , value of strings translated and, if data given, formatted again. is possible or know way solving given problem? thanks in advance additional question: strings normal objects, can subclass , add dynamic behaviour changes string in special cases? delphi strings not objects, can't add behaviours them. need develop own class. the windows way localize applica

i have following in data table , want display differently in second example below in datagrid. 1 know if there way this? userid questions answers 1 dog’s name belle 1 tell why should win. because need win 2 dog’s name leigh 2 tell why should win. i’ve never won before i'd result displayed below in grid view. userid question: dog’s name question: tell why should win. 1 answer: belle answer: because need win 2 answer: leigh answer: i’ve never won before this going: public class questionanswermap { public string question { get; set; } public string answer { get; set; } } class program { static void main(string[] args) { var list = new list<questionanswermap>();

i have several methods use similar linq statements different enough them in own methods. say, sake of arguemnt, had following linq snippet repeated across methods (the real snippets longer this): su.objid == serviceuserid cl.staffmemberid == staffmemberid if working in sql contatenate repeated sql follows: private string getrepeatedsql() { return "where su.objid = serviceuserid , cl.staffmemberid = staffmemberid"; } private void dosomething() { string mysql = "select * ...... lots of sql .." + getrepeatedsql() + ".. more sql"; } (usual health warnings around contatenating sql string noted). is there equivalent in linq? i'm sick of having make changes in several places - seems contravene dry principle. thanks! correct me if i'm wrong thought linq statements weren't executed until used them. (coming linq nhibernate) if case add whatever need existing statement. example: var temp=from x in sometable

my c++ program caches lots of objects, , in beginning of each major api call, want ensure there @ least 500 mb available api call. may either running out of ram+swap space (consider system 1 gb ram + 1 gb swap file), or may running out of virtual address in process.(i may using 3.7 gb out of total 4gb address space). it's not easy me approximate how data have cached, can purge of if becoming issue, , iteratively till have 500 mb available in system or address space (whichever becoming bottleneck). requirements find in c++ on 32 bit linux: a) find how ram + swap space free. b) how user space address space available process. c) how virtual memory process using. consider similar 'commit size' or 'working set size' of process on windows. any answers appreciated. take @ source vmstat : here . search domem() function, gather information memory (occupied , free).

hello question how works non executable exploit's, when non executable mean don't have file extension .exe, word exploits .doc or other. how did make executable action if not compiled? that varies exploit exploit. while .doc isn't executable format contain interpreted vba code malicious content hidden. when opened document there onopen event or such fired execute malicious payload. hence why office installations have macro's disabled default these days, far scope abuse. there plenty of things run on system without being .exe example .com , .vbs , .hta then there formats have no normal executable content can attacked in other ways, taking advantage of poorly written routines load files can allow things buffer overflows

in code below: string getname(type type) { return ((type)this.obj).name; } void run() { string name = getname(typeof(myclass)); } im getting "the type or name space cannot found (are missing using directive or assembly reference?)" error. should correct this? you can't cast instance ! type instance of type class, if want cast type, use generics void getname<t>() t : iobjectwithname { return ((t)this.object).name; } then can call string name = getname<myclass>(); if makes sens.

what best , efficient way to perform xsl transformation in ruby? have tried nokogiri, no matter tried results in: compilation error: element stylesheet the stylesheet works in xml editor. i'm using ruby 1.9.3 on linux. after poking around, found out nokogiri not support xslt 2.0: nokogiri uses libxml2, supports xpath 1.0/xslt1.0 my stylesheet written using xslt 2.0 syntax. updated title of question reflect this. wish nokogiri responded in more meaningful way. why want perform xsl transformation? curious. i'm working on website submits xml feeds other sites. every feed has different format, source of data feed same. so, instead of writing custom code every feed decided use xsl stylesheets, served database. way can create new feeds uploading new stylesheet. it possible use xslt 2.0 in jruby via saxon-xslt gem . don't think it's possible via other ruby implementations. mri ruby depend on libxml hasn't implemented xpath 2.0 yet. se

i'm reading preprint of 2nd ed of programming in scala, says "only scratched surface of can xml". there resources understanding entire xml support in scala 2.8? (right now, want know namespace handling, i'd have complete refer to). scaladoc doesn't count. this book author of scala xml supoort. scala xml support did not change on versions still date: http://burak.emir.googlepages.com/scalaxbook.docbk.html this article: http://www.codecommit.com/blog/scala/working-with-scalas-xml-support there's nice article here: http://www.ibm.com/developerworks/library/x-scalaxml/

i have dojo widget.for widget have 2 files a.js , a.html.now inside a.html have like <div id ="xyz" dojoattachpoint="xyz"> </div> the above line 1 line inside widget template , normal html div now in a.js make asynchronous call server.in callback function of remote method want modify text of span xyz.i tryed following 3 ways, none of them working. 1) dojo.byid("xyz").innerhtml = "some text" 2) this.xyz.innerhtml ="some text" 3) var mywidget = dijit.byid("pack1.abc.widget.widgetname_id"); mywidget.xyz.innerhtml ="some text" none of above approach works. when use approach 1 in other functions of a.js(non callback functions) works fine. you cannot hardcode id of widget in it's template. id has identify instance of widget-type uniquely, has given on creation. you can example like, programmatic in js: var mya = new mywidgets.a({}); mya.startup(); mya.xyz.in

i have messaging system contains default templates. example: you won x coins friend x wants share url y you so number of parameters varies in each message/template type. i thought of 4 types of solutions resolve issue: creating parameters table , represent each parameter type string. problem here user_ids represented strings joins slower. e creating parameters table each row contains following boolean tells if parameter int or string, , 2 other columns 1 type text , other type int. here we're kind of wasting space because whenever use int parameter row contains unused string cell. not create parameters table @ all, each notification contains parameters string contains each needed parameter seperator ; . 1 may slowest solution. creating 2 different tables each time of parameters: notification_param_int , notification_param_string , table contains each parameter in notification relevant table. solution may slower solution 2 because need check table fetch informatio

how can string appending parameter(s) request.url.query? let have parameter "value=100" request.url.query after appending "" "?value=100" "?" "?value=100" "?page=15" "?page=15&value=100" "?page=15&sort=col" "?page=15&sort=col&value=100" you cannot append parameters current query string. querystring readonly. if want manipulate querystrings in application use url helpers generate , manipulate urls. you checkout parsequerystring method useful in asp.net mvc application have routes , url helpers. sample usage: string query = "?page=15&sort=col"; var values = httputility.parsequerystring(query); values["value"] = "100"; query = values.tostring(); // page=15&so

i'm looking standalone c++ preprocessor. i'll use language, there's no point in running through full fledged compiler, it's limited script language, #define , #if , other directives me lot. for example, i'd writing file this: #define debug stuff #ifdef debug show message box or whatever #endif more stuff i found fits needs, mcpp . it's simple use preprocessor , supports output other languages command line switch.

i wondering if had alternative this. $(xml).find("a").each(function(){ $(this).find('b').each(function(){ $(this).find('c').each(function(){ $(this).find('d1').each(function(){ sectionvalidation.registerterms.setregistertermsarray(this); }); $(this).find('d2').each(function(){ sectionvalidation.registerterms.checkvalidvariations(this, val); }); }); }); }); it seems bloated , there has more elegant approach getting nested xml data. thank you you can @ least combine a through c selector decendant selector (space in-between), this: $(xml).find("a b c").each(function(){ $(this).find('d1').each(function(){ sectionvalidation.registerterms.setregistertermsarray(this); }); $(this).find('d2').each(funct

this small little hobby project in php. use 0sites.org server (linux os). try imitate functionalities of http://www.codepad.org , http://www.ideone.com . trying have online compiler/interpreter lanuages. as of now, can compile/run applications php exec(..) , unsure how going filter out harmful function calls c/c++ system(..) . also, have little idea how going prevent network access. i planning add few more languages. difficult implement things specific every language. wondering if there way stop things @ more general level. i have thought on lines of parsing code manually , comment out problematic lines of code. since there more 1 way things, can broken. :-p any ideas/suggestions/pointers ? shall highly grateful same. :-) (ps: hobby project. want make professional possible.. ) you need os support creating these sandboxes. approach involving filtering source code going have security problems, , nightmare maintain. just think: if implement parser correctly, there

i'm new mysql , have choice regarding mysql database structure new database. can have: table1:(id,text1,text2,text3,text4,up text7) or table1:(id,int1,int2,int3,...up int7) int values link table 2 unique index table2:(id2,text) so basically, should put text in columns in single table or saparate , store index values in 1 table , text data in second table... queries given id code, return strings text 1 text 7. table large, ~1 million id's (meaning table 2 if method 2 used have ~7 million entries) which method faster in opinion? edit1: each text 250 letter characters in length. edit2: clarify, given id , query table getting 7 text items id. query done on tables , information ever required. need know faster use. if neither, please offer better way! won't make speed difference if you're not querying based on text. keep simple , use 1 table. if have query text, you're going want change it.
