i have created 2 timespans below: timespan currentts = timespan.fromseconds(43995); //12:13:15 timespan towtime = timespan.fromseconds(303072); //12:11:12 i'm trying find difference in minutes (by seconds i'm passing it, looks on different days). hoping around 2 minutes difference, in reality, i'm getting -57 minutes. int timedifference = (int)currentts.subtract(towtime).minutes; can explain doing wrong? if looking difference between minutes (not including days, hours or seconds), can use double timedifference = currentts.minutes - towtime.minutes; // 2 this difference of minutes component though. other people have said, these times separated 3 days, timespan possibly isn't ideal. or, if want seconds included well, can use timespan minutes1 = new timespan (0, currentts.minutes, currentts.seconds); timespan minutes2 = new timespan (0, towtime.minutes, towtime.seconds); double timedifference = minutes1.totalminutes - minutes2.totalminutes /

so, i'm attempting use this: http://blogs.msdn.com/b/priozersk/archive/2010/09/17/customizing-picker-box-dialog.aspx however, want normal pickerboxdialog (just text) i'd attach id it, can reference selection user picked. however, after building own class pass in, still cannot text display (ie @ all) within pickerbox. does have experience? copied code , still no luck... if want normal picker box shouldn't have worry customizing template (unless want display id too). the way reference object selected user in closed event handler: void dialog_closed(object sender, eventargs e) { var picker = (pickerboxdialog)sender; var selected = (yourcustomobject)picker.selecteditem; } in other words shouldn't need id of selected object because can reference select object directly.

i use code full url: $actual_link = 'http://'.$_server['http_host'].$_server['php_self']; the problem use masks in .htaccess , see in url not real path of file. what need url, written in url, nothing more , nothing less—the full url. i need how appears in navigation bar in web browser, , not real path of file on server. have @ $_server['request_uri'] , i.e. $actual_link = "http://$_server[http_host]$_server[request_uri]"; (note double quoted string syntax perfectly correct ) if want support both http , https, can use $actual_link = (isset($_server['https']) ? "https" : "http") . "://$_server[http_host]$_server[request_uri]"; editor's note: using code has security implications . client can set http_host , request_uri arbitrary value wants.

i have large 4 dimensional matrix, , wish 1) find minimum of 2 of dimensions (i.e. 4000x4000 result) , 2) count number of elements in last 2 dimensions less (lets say) 5 times minimum (i.e giving result of 4000x4000). i'm bit stumped how without reverting loops some code might aid description: a = rand([4000,4000,7,7]); b(:,:) = min(a(:,:,1:7;1:7)); % isn't quite right? c = size( < 5*b ) % totally wrong any pointers great - many thanks! if understood correctly, following should job: mn = min(min(a,[],3),[],4); num = sum(sum(bsxfun(@lt, a, 5*mn),3),4)

i have toolstripbutton performs action. user clicks button , button disabled prevent action being performed twice. after action complete button re-enabled. works perfectly...except: because button disabled not fire "mouseleave" event , result appearance of button not updated. absolutely clear, when mouse enters toolstripbutton button highlighted in orange (by default) black box around it. highlight not being removed when re-enable button. mouse cursor is, time, long gone control. mousing on button naturally fixes button redrawing it. what method on toolstripbutton "resets" appearance. such method may exist on toolstrip, despite searching have been unable find this. as alternative fire "mouse leave" event on button directly. far know there no way in c# .net. any advice @ point in time appreciated, naturally don't want tear application , replace tool strip. update: reproduced problem, trying figuring out! i didn't better way o

yesterday, piece of code caused me headache. fixed reading file line line. ideas ? the while loop never seems executed though no of lines in file greater 1. val lines = source.fromfile( new file("file.txt") ).getlines; println( "total lines:"+lines.size ); var starti = 1; while( starti < lines.size ){ val nexti = math.min( starti + 10, lines.size ); println( "batch ("+starti+", "+nexti+") total:" + lines.size ) val linessub = lines.slice(starti, nexti) //do linessub starti = nexti } this indeed tricky, , it's bug in iterator . getlines returns iterator proceeds lazily. seems happen if ask lines.size iterator goes through whole file count lines. afterwards, it's "exhausted": scala> val lines = io.source.fromfile(new java.io.file("....txt")).getlines lines: iterator[string] = non-empty iterator scala> lines.size res4: int = 15 scala> lines.size res5: i

i planning develop web app detect faces in jpeg image. use tomcat deployment. want on how proceed. i dont want code. flowchart of steps do. want avoid use of third party libraries face detection. please list options. any information, algorithm, resource helpful. thank you.. i recommend using 3rd party lib such opencv. you'll want @ haar feature detector. there's info here http://opencv.willowgarage.com/wiki/facedetection , plenty more on opencv mailing list. there java bindings opencv http://code.google.com/p/javacv/ . might easiest produce separate command line util shell out in tomcat.

i have listview in wpf application use dynamic binding . wish insert in cell of row checkbox instead showing boolean value specific row. should apply rows , should offcourse enable me unset , set (it update object in code) can last part myself. need figure out how put checkbox there. it possible ? ideas ? here xaml: <listview margin="385,91,12,120" name="lsttransactions"> <listview.view> <gridview> <gridviewcolumn displaymemberbinding="{binding description}" width="220">description</gridviewcolumn> <gridviewcolumn displaymemberbinding="{binding path=montantestimation, stringformat='{}{0:c}'}" width="100">estimation</gridviewcolumn> <gridviewcolumn displaymemberbinding="{binding path=mo

so i've been following answer: adding custom cursor in xna/c#? ... custom mouse cursor working on xna. i've done solution, no error, still no custom cursor (it still shows windows default one). i'm unsure on really... i created getcursorpos method @ bottom of game1.cs file, included following declarations @ begining of game1 class: private mousestate mousestate; private int cursorx; private int cursory; the code in loadcontent giving me error: cursortex = content.load<texture2d>("cursor.png"); so replaced with: cursortex = content.load<texture2d>("cursor"); ("cursor" png) what doing wrong?... said, no error :( i suspect need update mouse's position, using mousestate = mouse.getstate(); (put in game's update method, before update cursorpos variable).

i have access .mdb database table looks similar to: +---------+------+--------+ | date | value | +---------+------+--------+ |2011-05-04 12:00 | 45.9 | |2011-05-05 12:00 | 21.2 | |2011-05-06 12:00 | 32.2 | |2011-05-07 12:00 | 30.4 | |2011-05-08 12:00 | 40.4 | |2011-05-09 12:00 | 19.8 | |2011-05-10 12:00 | 29.7 | +-------+---------+-------+ i create query return values derived subtracting 1 value previous day value. for example: query calculate (21.2-45.9) , return -24.7 (32.2-21.2) , return -11.0 (30.4-32.2) , return -1.8 etc how can accomplish in select statement? you can use query employs self-join on table in question: select t.datevalue , t.singlevalue - iif(isnull(tnext.singlevalue), 0, tnext.singlevalue) test t left join test tnext on t.datevalue = dateadd("d", -1, tnext.datevalue) t.datevalue = #2011-05-08 12:00#; outputs datevalue expr1001 ---------------------- ---------------- 05/08/2011 12:

i'd have array in javascript each item contains 2 properties instead of 1, how possible? the following adds 1 property item default: var headercellwidths = new array(); headercellwidths.push(100); this enables me access item using [0][normalcellwidth] but i'd able have e.g. [index][normalcellwidth][firsttemplatecellwidth] e.g. [0][100][25] e.g. headercellwidths.add(100, 25); one solution create own customarray maintains 2 separate array instances isn't there better way? thanks, you can add entries objects array. try this: headercellwidths.push({normalcellwidth:100, firsttemplatecellwidth:25); you access items using: headercellwidths[0].normalcellwidth , headercellwidths[0].firsttemplatecellwidth

using doctrine, i'm doing query kinda this: $query = doctrine_query::create()->select('id,name')->from('people'); return $query->fetcharray(); it returns object similar following array of arrays: array(3) { [0]=> array(4) { ["id"]=> string(1) "34" ["name"]=> string(7) "john" } [1]=> array(4) { ["id"]=> string(1) "156" ["name"]=> string(6) "bob" } [2]=> array(4) { ["id"]=> string(1) "27" ["name"]=> string(7) "alex" } } notice how array's keys count 0, 1, 2, etc? question: possible specify want key values come from? example, key values in above case 34, 156 , 27. i noticed in doctrine doc's both fetcharray() has parameters can feed them, doesn't parameters are... public array fetcharray(string params) http://www.doctrin

how can write code function (complex contour) similar in mathematica: the direct way use graphics primatives (although think prefer felix's polarplot solution) with[{q = pi/6}, graphics[{circle[{0, 0}, 1, {q, 2 pi - q}], arrowheads[{{.05, .8}}], arrow[{{cos[q] + 2, sin[q]}, {cos[q], sin[q]}}], arrow[{{cos[q], sin[-q]}, {cos[q] + 2, sin[-q]}}], fontsize -> medium, text["\[scriptcapitalc]", {2, sin[q]}, {0, -2}]}, axes -> true, plotrange -> {{-4, 6}, {-4, 4}}]] i guess if want actual function contour, maybe like contour[t_, t0_: (5 pi/6)] := piecewise[{ {exp[i (t + pi)], -t0 < t < t0}, {t - t0 + exp[i (t0 + pi)], t >= t0}, {-t - t0 + exp[-i (t0 + pi)], t <= -t0}}] parametricplot[through[{re, im}[contour[t]]], {t, -8, 8}, plotpoints -> 30] and add arrows plot, guess you'd have add them in manually (using epilog or drawing tools) or use 1 of packages modifies built-in plots.

i have developed ajax search component query google search appliance. makes ajax call php script grabs xml gsa , encodes json , sends browser. there, jquery template plugin rest. process works should. however, when navigate away search page (e.g., click on result link) , later wish return search results, ie , chrome not retain search results , position on page, while ff, opera, , safari retain the ajax content appended dom , position on pae. in ie , chrome, hitting , seeing blank page w/ no results. is there reason why browsers behave differently? (some browsers show appended content when go page, don't) is there way easy way fix without type of session or state or storage? thanks how when hit search change location of page without redirecting ( ex: http://myurl.com/search.html#mysearchtext(url encoded)) then search. on onload event of page check #xxxxx in url, , if 1 exists make search. it serves 2 purpose : - way action work :p - way can link search

i'm trying set validation expression asp.net regular expression validator control. validating creation of user name, want limit number of characters, , want prevent them using spaces. here's i've got far: ^.*(?=.{5,20})(?=.*\w{5,255}).*$ the \w{5,255} part prevents spaces , special characters (except underscores, apparently). have no idea how "5,255" makes work, does; copied somewhere else. the main problem i'm having if first or last character space (or special character), passes validation, not acceptable. can me? i'm sure simple, know next nothing regular expressions. you can use simpler this: ^[a-za-z0-9_]{5,255}$ this allow alphanumeric usernames between 5-255 characters in length.

is best practice of using uris in json (or xml) representation of rest resources, example for example resource has list of attachments, every attachment has id can used retrieve using url http://myserver.com/resources/attachments/ : { filename: "screenshot.png" contenttype: "application/octet-stream" id: 52004 } should add uri element like { filename: "screenshot.png" contenttype: "application/octet-stream" id: 52004 uri: /resources/attachments/52004 } yes, think should include link each item in collection. api not restful (and more importantly, not useful) without links. if think human client rather have link instructions on how request item id, same applies non-human client. should give client idea of how item relates current resource providing link relationship: link : { uri: "/resources/attachments/52004", rel: "/rels/file-attachment" } john

i sorting ienumerable of objects: var sortedobjects = objects.orderby(obj => obj.member) where member of icomparable type. sort seems put objects obj.member == null @ top. behaviour want, can consider stable respect future .net frameworks? there way can make 'nulls low' behaviour more explicit? to make behavior more explicit: var sorted = objects.orderby(o => o.member == null).thenby(o => o.member);

i looking relative-simple approach one-level image zoom in, slices of images loaded , appear viewed in area (like google maps). have lot of images, manual-slicing maybe out of question. preferably no flash/silverlight. i had @ of jquery solutions none quite fits looking for. similar implementation can seen on uk national gallery site ( http://www.nationalgallery.org.uk/paintings/georges-seurat-bathers-at-asnieres ), or google+ intro site ( http://www.google.com/+/demo/ ) thank you. check out jquery overscroll plugin , this question . should trivial make script slices images using php's gd .

i installed python 2.6 on mac os x (snow leopard) , when start idle keeps quitting! i removed installations of python by: rm -rf /library/frameworks/python.framework and re-installed , still same problem :( any ideas might be? thanks you undoubtedly using version of python dynamically linking apple-supplied tcl/tk 8.5 in os x 10.6. version of tcl/tk flawed. there several easy ways avoid problem, simplest being install current python 2.7 (or out-of-date 2.6) installer python.org and, 64-bit/32-bit installers, install up-to-date activetcl 8.5 . there more information here . i should add that, while far common problem idle on os x 10.6, possible there cause. take @ system.log (with console.app ) launching idle.app or start idle shell , see error messages being reported.
