in .net c#4.0 .net chart control have code generate pie chart: chart.series[0].charttype = seriescharttype.pie; foreach (order order in ordercollection) { // if set point.legendtext = order.username, .group erase chart.series[0].points.addxy(order.username, order.total); } chart.datamanipulator.sort(pointsortorder.ascending, "x", "series1"); chart.datamanipulator.group("sum", 1, intervaltype.months, "series1"); this works well, generates pie chart top 10 users showing total order sum. set datapoints' legendtext order.username property. problem is, datamanipulator.group overwrites series datapoints. if set legendtext in foreach loop, erased after group call. and after group call, don't see way retrieve correct username datapoint set legendtext. what best approach situation? as solution, used linq group datasource , dropped use of datamanipulator.

i have text box in program user can input text , format in html ( tags around bold text, etc). i using mapi32.dll open email window in outlook text, seems mapi not interface html, left raw html in there, displaying actual <> tags. so, pursuing alternative ways pop open email window, html text formatted. have read suggestions of using smtp, still allow me pop open email window user's email program, or going send email directly? prefer former, email popping open in user's email client. thanks. seems me simplest solution to use 1 of many wysiwyg html text editors out there display/edit email, use smtp send it. here editor have used in past pretty simple: http://www.codeproject.com/kb/edit/editor_in_windows_forms.aspx

i thinking using enum type manage i18n in java game i'm developing curious performance issues can occur when working enums have lots of elements (thousands think). actually i'm trying like: public enum text { string1, string2, string3; public string text() { return text; } public string settext() { this.text = text; } } then load them can fill fields: static { text.string1.settext("my localized string1"); text.string2.settext("my localized string2"); text.string3.settext("my localized string3"); } of course when i'll have manage many languages i'll load them file. what i'm asking is is obect allocated (in addition string) every element? (i guess yes, since enums implemented objects) how right element retrieved enum? static @ compile time? (i mean when somewhere use text.string1.text() ). should constant complexity or maybe replaced during compiling phase.. in general, approach or sh

i feel silly asking seem have forgotten how use sine effectively. i'm working on ipad app i'm in objectivec, , i'm trying uiview oscillate slowly. using position.y + sin(counter) makes move fast vibrates , can't seem define period slow down. i've found code samples (mostly generating sound waves) , combine many things 1 line of code can't pull apart. can explain should doing? sin (and cos) take parameter in radians. name counter suggests you're not using radians. so, need determine how many oscillations per second want. then, can measure time between last , current animation 'frame'. whole wave 2pi radians, y = sin(2pi * time * occilationspersecond) * amplitude.

i learning asp.net mvc form processing , confused following: what happens if push refresh button on browser? makes post or request? this dependant on last call made browser current data. eg: a) if submitted form, performing post , hit refresh, browser post. b) if clicked link took page, performing get, you'll refresh perform get. if you're starting out understanding get/post methods, there nice pattern should understand not in situations data posted again , again users refresh browser after post: http://en.wikipedia.org/wiki/post/redirect/get and an example asp.net mvc

so have created piece of software wanna package , post arch linux user repositories, aur, -should note, have never packaged distro before - , have got packaged , installed on own machine via arch's package manager pacman successfully, wondering how on earth gonna structure folders , files? normally when wrote software, use structure: build/ | src/ | makefile as minimum, , in case of piece of software, makefile nothing more compile .cpp file src/ build/. make arch package, had create .rc file, use program daemon , pkgbuild file, file tells makepkg program how build installer-package - these 2 files, though, specific arch. if wanna package program debian, need set of files too, these files work debian. now, can't put .rc file , pkgbuild file in programs root folder, since "be mess" if had files build package debian, put distro-specific files? need have in programs root folder -at-least- able keep track of it, , initial thought go structure distro/arch/ arch li

here "simplified" class can mapped using nhibernate; public class template { public virtual int id { get; private set; } public virtual string name { get; set; } } as id field has private setter can no longer have code in our application manually set id field; var defaulttemplate = new template { id = (int)templateenum.default, name = "default" } here manually creating defaulttemplate object can assign anything. other templates manually created users , saved database. any ideas how can still achieve kind of functionality? please note: c# winforms, .net 3.5 , don't want use reflection this. i this, if feasible: public class template { public virtual int id { get; private set; } public virtual string name { get; set; } public static readonly template default = new template() {id = (int)templateenum.default, name = "default"}; } then, can 'get' default template, without having instantiate outside of template

i turned firewall on, , while running multiple rubies, got question do want application "stoned" accept incoming network connections? clicking deny may limit application's behaviour. setting can changed in firewall pane of security preferences. after googling, worked out wasn't malicous app (and not this stoned !), maglev (presumably "stoned" being "stone daemon"). unless i'm serving web content or otherwise acting on network, need enable "stoned"? if you've installed maglev, "stoned" refers stone process manages repository image (where ruby objects stored). can deny stoned (and others, e.g., topaz, netldi, gem, etc.) , things should work long processes on same machine (i.e., run maglev-ruby on same machine running stone). if trying connect remote clients (usually remote vms) stone, you'll need allow incoming connections netldi , gem.

i'm writing online application form , 1 of pieces of data i'm trying collect users education history; school name, school city, years there , achievements while there. data collected anywhere between 0 4 different schools , user dynamically adding more fields if required. my question how captured within database since don't know how many schools user adding? can done in 1 table, or need create multiple tables , capture education data in separate table? any or pointers appreciated. thanks. you need separate tables. 1 row per person, , row per school. schools can related people using either personid in school table, or additional table representing "person attended school" relationship. any association of 1 entity (person) multiple other entities (schools) requires more 1 table.a general rule follow 1 table per "entity", plus additional tables many-to-many relationships.

i want pass reference of class object called "a" in constructor. , use "validate" function check it. like that: test1.pm my $object = object1->new; $newobject = object2->new({ param1 => $object, }); test2.pm sub new { $class = shift; (%options) = validate (@_, { param1 => { type => scalarref, default => undef}, }); ... } the problem i'm not sure type of parameter param1. tried "object" , "scalarref" there errors "scalarref not allowed while strict sub". what type should use? it looks you're trying quasi- moose thing here. in moose, don't create new subs, because moose you. if need anything--you create build sub. the perl (5) base object system doesn't work moose, 'scalarref' or whatever make in base perl. do realize passing hashref new ? do realize vaildate getting 2 hashrefs? validate( {}, {} ) and if scalarref has not be

is && same "and", , || same "or" in php? i've done few tests, , seems behave same. there differences? if not, there other php signs have word equivalents , think makes code easier read? and , or have higher lower precedence && , || . more exact && , || have higher precedence assignment operator ( = ) while and , or have lower. http://www.php.net/manual/en/language.operators.precedence.php usually doesn't make difference, there cases when not knowing difference can cause unexpected behaviour. see examples here: http://php.net/manual/en/language.operators.logical.php

is there way see rowcount set to? the component used call stored procedure has option limit how many rows returned, apparently setting rowcount. 1 stored procedure returns single aggregated row, intermediate queries return more limit , getting truncated. function of generic , used call other stored procedures; other procedures may need limit. right setting rowcount large number @ top of stored procedure , setting (hard-coded) regular limit before return result. don't maintain component calls stored procedures may not know if returned row limit changed. i'd set local variable current rowcount value, , set @ end. there way see rowcount set to? if query sys.dm_exec_sessions dmv return number of rows returned on session point (should of course same @@rowcount). select row_count sys.dm_exec_sessions session_id = @@spid you might able play around see if can use it right setting rowcount large number @ top of stored procedure you can set rowcount 0 ,

i aware can share simple objects using localconnection, not (in limited testing) appear work netconnection or netstream. in short, wish have single swf acts netconnection proxy other swf files in html page. client swfs require direct access netstream objects on proxys netconnection. is @ feasible, or each client swf require own netconnection? i aware build entire application in flash , utilize single netconnection internally, not want do. thanks! that depends on want it. netconnections can stream videos , there no way have shared between different swfs on same page. on other hand, can used simple loading of data. small enough pass through localconnection without issues, depends on size of data. you need have netconnection complete load before being able send through localconnection . netconnection inaccessible other swf's, allow load data , send it. remember: localconnections serialize objects , not keep class data when arrives @ target location.

i have following in vb: dim sources = source in importsources select new _ {.type = source.key, .source = source.value.name} dgridsourcefiles.datasource = sources when debug, sources shows in-memory query , has 2 records within. yet datagrid view not show records. so why won't work? suggestions can either vb or c#... update when use: dim sources = (from source in importsources select new _ {.type = source.key, .source = source.value.name}).tolist() ...the datasource displayed. your linq query lazily evaluated , implements ienumerable<t> interface (as far know), means results not established until enumerator calls movenext somewhere (as happens within foreach loop, example). it seems datasource property not enumerate contents in way. it's expecting implementation of ilist (or 1 of few other interfaces—see below) can access items index. used internally control sorting, filtering, etc. in mind, it's setting datasource proper
