i'm loading data sql server database this: sqlcommand cmd = new sqlcommand("select * x", conn); cmd.commandtype = commandtype.text; datatable dt = new datatable(); sqldatareader rd = cmd.executereader(); dt.load(rd, loadoption.preservechanges); issue: the load() function initializes table columns columnname , datatype , looks deeper database, , adds constraints allowdbnull , autoincrement , maxlength , etc. however, leads problems in application, because want further process data internally. so, possible load() setting basic properties (which come directly select statement), without setting allowdbnull , maxlength , , on? or need clean these values after load() ? or there alternative calling load() ? if don't want behaviour don't use datatable.load dbdataadapter.fill(datatable) : datatable dt = new datatable(); using(var da = new sqldataadapter("select * x", conn)) da.fill(dt); the fill operation adds rows des

i'm trying change text in title tag based on tag 's direction value: <li ng-repeat="t in tags"> <div class="tag" ng-class="{'green-up': t.direction == 'positive', 'red-down': t.direction == 'negative', '' : t.direction == 'stagnant'}" title="percentage increase" ng-if="">{{t.name}}</div> </li> the direction either positive , negative or stagnant , should correspond title="percentage increase" title="percentage decrease" or title="percentage" what angular syntax best used in case? why not set tag settings object $scope.taginfo = { positive:{ class:"green-up", title:"percentage increase" }, negative:{ class:"red-down", title:"percentage decrease" } } and call

it conventional use pass statement in python following piece of code. try: os.makedirs(dir) except oserror: pass so, 'pass' bascially not here. in case, why still put few codes in program? confused. many time , attention. it's parser. if wrote this: try: # code except error: and put nothing in except spot, parser signal error because incorrectly identify next indentation level. imagine code: def f(x): try: # except error: def g(x): # more code the parser expecting statement greater indentation except statement got new top-level definition. pass filler satisfy parser.

i'm writing small javascript text expansion library. library use web worker , packaged bower. when installed via bower parser script not found (i 404) because browser looking relative root of consuming site , not relative bower script being consumed (both scripts contained in same folder). appears correct behavior . my question: how should workers used in combination bower such required scripts can loaded without hard-coding bower_components/ path? function expander(args) { ... this.parser = 'parser.js'; this.worker = new worker(this.parser); ... } i use grunt. gulp might bit easier starting out since can debugged missing key component needs. there set of libraries wiredep, build-file , watch enable wanting do. wiredep watches bower directory , automatically add js files dependencies in bower.json html , watch can configured watch type of file in directory change. build-file enables configure template , pass variables use dynamically build j

with large payloads, seeing when json converted pojo, taking lot of time. internally uses jackson. wondering if there way can configure resteasy use afterburner module seems better performace. you can configure objectmapper used. 1 way can done through contextresolver , see here . register module objectmapper (as seen in documentation ).

i've got mysql free-text search , running in rails app. if search 'regular guitar cable' 'guitar' , 'cable', want. now i've installed sphinx , thinking-sphinx gem, , i've found search 'regular guitar cable' doesn't return results @ all. what's worse if search 'guitars' nothing! instead i'm finding have search 'guitar' instead i.e. need enter exact term. this problematic because few of users search 'guitar' , instead it's more search 'red guitar' or 'cheap guitar' , need sphinx bit smarter. how can make want without having add every single adjective in english dictionary stop-word file the following resolved problem! product.search "\"#{search_text}\"/1" the /1 @ end makes work, , it's called quorum operator .

i typing python menu , wondering if there way make program return place. instance: print 'choose: ' = raw_input (' apple[a], grape[g], quit[q] ') if a=='a': print 'apple' elif a=='g': print 'grape' elif a=='q': print 'quit' print 'are sure?' print 'yes[y], no[n]' b=raw_input ('choose: ') if b=='y': quit() elif b=='n': print 'returning menu' in part is: `b=raw_input ('choose: ') if b=='y': quit() elif b=='n': print 'returning menu'` how return first apple\grape menu? there way user doesn't have quit , instead return main menu? i either use function recursively or while loop. since there while loop solutions, recursive solution be: from sys import exit def menu(): = raw_input("choose: apple[a], grape[g], quit[q] ") if == 'a'

i have written cli utility in python , have list 1:m list-items of paths like: i want display list in more readable manner like: [ (1, '/path/here'), ('path/here/again'), (2, 'a/different/path/here'), ('another/path/here') ] or in table-like format (e.g.): 1 /path/here path/here/again 2 a/different/path/here another/path/here note, list have 20 or more list-items. thanks! to start: >>> mylist = [ ... (1, '/path/here', 'path/here/again'), ... (2, 'a/different/path/here', 'another/path/here') ... ] play join() , map() , , str() , along python 3's nice print() function: >>> print(*('\t'.join(map(str, item)) item in mylist), sep='\n') 1 /path/here path/here/again 2 a/different/path/here another/path/here or try string formatting instead of join() , map() : >>> print(*(str(col) + '\t' + (len

i trying use following code had found/edited in post. use function "isvalidimageurl()" instantly return result on fly. since function runs in separate thread, had trouble getting value, example, if had "return true;" in place of "isvalid=true;" "undefined" in return. tried use global variable "isvalid", seem 1 step behind, meaning need call function twice, result first call. what fundamentally missing? or able suggest method can it? thank you! <script> var isvalid; function isvalidimageurl(url) { $("<img>", { src: url, error: function() { isvalid=false; }, load: function() { isvalid=true; } }); } isvalidimageurl("https://www.google.com/logos/2012/hertz-2011-hp.gif"); alert(isvalid); isvalidimageurl("http://google.com"); alert(isvalid); </script> the

i know how set expected exception while unit testing using phpunit's setexpectedexception() method and/or equivalent annotation. but reason i'm not able same while testing logic around fopen() here example: class abstractfilereadertest extends \phpunit_framework_testcase { public function test_invalidfileexception() { $filepath = 'incorrect/file/path.csv'; $this->setexpectedexception(\exception::class); fopen($filepath, "r"); } } for unit test on file system it's better use vfsstream vfsstream stream wrapper virtual file system , tests it's cleaner solution write there real file system.

the mobile site i'm working on different desktop version. need make ajax call via mobile site bring in data desktop version. seems ajax call make request on calling version of site. this code returns mobile site data when called on mobile site: $.ajax({ type: "get", url: window.location.href, success: function(data) { var response = $(data); //returns mobile site data } }); is there way force request use desktop version? you're making ajax request the current url : url: window.location.href this highly unconventional. more point, browser doesn't know or care difference between "desktop" , "mobile". makes requests , displays responses. if current url doesn't handle ajax request you'll need make request url does: url: 'somespecificurl' to make easier , consistent through diff

with navigation view controller, can give "cover vertical" transition style animation. however, having trouble replicating page view controller. options given in story board "scroll" , "page curl". there way programmatically? it looks little bit tricky should work : create uiviewcontroller container controller. add uipagecontrol ever want. programmatically add uinavigationviewcontroller child of container , add view view hierarchy. can use instantiateviewcontrollerwithidentifier: of main storyboard , don't forget set constraints if you're using autolayout. use delegate between container , uinavigationviewcontroller or parentviewcontroller property of uinavigationviewcontroller change uipagecontrol when user navigates in uinavigationviewcontroller. uipageviewcontroller 1 single thing. of time prefer using custom container controller rather using it.

the loaders in asynchronously getting data data source. can achieve same effect using handlers , can kick off thread or execute executor , can fetch data in thread. once data fetched, can update ui using ui handler message mechanism. why go coding complex loaders when can achieve same using handlers . loaders introduced make easier in implementing correct data loading on android platform. means: doing heavy stuff on background thread safely introducing loaded data in ui caching of data, means improving speed loaders can live outside activity lifecycle, if have config change data not destroyed loaders reloaded once data store changes using handlers,executors, or asynctasks not take account above points. have manage yourself, , work android developers put loaders implementation. ie. using asynctask loading data requires watch out screen rotations, ie. must somehow retain reference asynctask might still in background once activity recreated due screen rotation.

i have simple function: w(x) := c1*cos(x)+c2*sin(x)+c3*cosh(x)+c4*sinh(x) i evaluate @ x=l , get: c1*cos(l)+c2*sin(l)+c3*cosh(l)+c4*sinh(l) sometimes equations long , complicated. want find coefficient of each c's such as: coeffs c1: cos(l) coeffs c2: sin(l) coeffs c3: cosh(l) coeffs c4: sinh(l) however, coefficient of 1 variable @ time. find coefficients of variable. when add multiple coeffs, not show coefficients shows different such as: ({2,1},{1,1}) is there way find coefficients @ 1 shot? it if post little more expect get? can attach worksheet example? the ({2,1},{1,1}) expression seeing mathcad's default display nested array (that is, array contains other arrays). show array in full: in mathcad 15 (or lower), double click on result (ie, ({2,1},{1,1}) ) , should see results dialog box. select display options tab, select matrix 'matrix display style' drop-down menu, tick 'expand nested arrays' , click ok. should show

i working on socket.io "hello world" via mean stack application, , right away chrome tossing funky errors way. honest, in debugging effort, i'm not sure begin. initial questions were: why xml being used instead of json? what no 'access-control-allow-origin' header present on requested resource. mean? the entire error message below, , in advance advice y'all able give. cheers, peter xmlhttprequest cannot load http://localhost/socket.io/?eio=3&transport=polling&t=1435600202687-6. no 'access-control-allow-origin' header present on requested resource. origin 'http://localhost:9000' therefore not allowed access. response had http status code 404. try including socket.io lib directly socket server: <script src="http://localhost:9000/socket.io/socket.io.js"></script> the error "no 'access-control-allow-origin' header present on requested resource." means server doesn't

this question has answer here: c# variance problem: assigning list<derived> list<base> 4 answers i'm using reflection property icollection<testcastchild> , cast icollection<icastbase> . testcastchild implement's icastbase. when try cast collection, cast fails. i'm sure i'm missing simple. can't see why fails. public interface icastbase { int id { get; set; } } public interface icastchild : icastbase { string name { get; set; } } public abstract class testcastbase : icastbase { public int id { get; set; } } public class testcastchild : testcastbase, icastchild { public string name { get; set; } } public class testcastparent : testcastbase { public virtual icollection<testcastchild> children { get; set; } } then test: [testmethod] public void testcast() { var parent = new testcastp

okay, i'm doing basic xml tutorial , trying put code in: parser = etree.xmlparser(remove_blank_text=true) root = etree.xml("<root> <a/> <b> </b> </root>", parser) etree.tostring(root) and i'm getting error pointing parser line saying 'remove_blank_text' invalid keyword argument function i have sneaking suspicion lxml somehow not installed or imported or whatever. have eyes cross @ "installation" instructions; in very, plain english, how install/reinstall lxml? (edit: double checking, yes, this: import sys lxml import etree does indeed yield "no module named lxml". okay, how install lxml? installing lxml on windows surprisingly tricky business. wasn't ever able work until found wonderful resource: unofficial windows binaries python projects .

i want find best match level of threshold. here did values staying @ 0. cvmatchtemplate(src, tmp, result, cv_tm_ccorr_normed); cvpoint minloc = new cvpoint(); cvpoint maxloc = new cvpoint(); doublepointer min_val = new doublepointer(); doublepointer max_val = new doublepointer(); cvminmaxloc(result,min_val, max_val, minloc, maxloc, null); i don't double pointers required mothode. min_value , max_value staying @ 0 cant find best matches. thanks in advanced.using javacv. in example here used primitive doubles, not double type , defined arrays, not objects. so, why don't give shot , let know if make difference. cvmatchtemplate(src, tmp, result, cv_tm_ccorr_normed); double[] min_val = new double[2]; double[] max_val = new double[2]; cvpoint minloc = new cvpoint(); cvpoint maxloc = new cvpoint(); cvminmaxloc(result, min_val, max_val, minloc, maxloc,null); __update__ i found following code here // match template function opencv cvmatchtemplate(src, tm

in matlab (r2015a), want style title of plots using latex. this working fine functions, not if there's power in equation. the below code works, , shows formatted title right, , unformatted title left. it shows warning: warning: error updating text. string must have valid interpreter syntax: y = x^2 syms x y eq = y == x^2; subplot(1,2,1) ezplot(eq) title(latex(eq),'interpreter','latex') eq = y == x+2; subplot(1,2,2) ezplot(eq) title(latex(eq),'interpreter','latex') edit: i found out can work appending $ on both sides. seems weird have this. so works: title(strcat('$',latex(eq),'$'),'interpreter','latex') solution the problem can solved adding $ -signs before , after generated latex-expression. can change « title -lines» to: title(['$',latex(eq),'$'],'interpreter','latex') an alternative use strcat proposed in question. explanation si

i have page , , page need value other different page. i want retrieve 6 numbers "números sorteados" box. so far succeeded in whole web page this: webrequest request = webrequest.create("http://www1.caixa.gov.br/loterias/loterias/ultimos_resultados.asp"); webresponse response = request.getresponse(); stream data = response.getresponsestream(); string html = string.empty; using (streamreader sr = new streamreader(data)) { html = sr.readtoend(); } after that, can't select these number html. here's quick way numbers using htmlagilitypack : public async task<list<string>> getnumbers() { // getting number of microseconds since jan 1st, 1970 var microseconds = (long)(datetime.utcnow - (new datetime(1970, 1, 1, 0, 0, 0))).totalmilliseconds; // creating webrequest , passing parameter var request = webrequest.createhttp( string.format( "http://www1.caixa.gov.br/loterias/lot

i'm trying write function find similiar files name (song.mp3, song1.mp3, (1)song.mp3) in specified folder. have now: def print_duplicates(source): files_list = [] new_list = [] dirpath, dirnames, filenames in os.walk(source): fname in filenames: if ('\w*' + fname + '\w*') in files_list: new_list.append(os.path.join(dirpath, fname)) else: files_list.append(fname) in new_list: print(a) if filename wasn't before in files_list added, if added new_list path. way have list of 'duplicate' files. it's not working, new_list remains empty. correct mistakes? part of code wrong? if want use regex in code, need use re module. so change line, if ('\w*' + fname + '\w*') in files_list: to, if re.search(r'\w*' + fname + r'\w*', files_list): which same as, if fname in file_list: because \w* means 0 or more word char
