i have observable collection marketprices , observable collection have bind itemscontrol below . 1) don't want show items in observable collection , want show items user click add , selected pair (gbpjpy, usdgbp..) needs show in items control. 2) if user changed item in comobobox gbpjpy usdgbp , price( datatemplate) of gbpjpy need update usdgbp. how can achieve both conditions. please note below code doesn't have real-time update in project have relatime price update well, observable collection updates on price changes. code far public class pricemodel : inotifypropertychanged { private double _askprice; private double _offerprice; private string _selectedpair; public pricemodel() { pairs = new observablecollection<string> {"gbpusd", "gbpeur", "usdgbp", "gbpjpy"}; } public double askprice { { return _askprice; }

i'm trying link numerical (octave/matlab) values in array string values in array how can go doing this. reason i'm trying sort array based on numerical values. example: array=[1,2,'filename1';3,4,'filename2';5,6,'filename3'] (i know incorrect , give error) this i'm trying can sort based on first or second column , have third column "linked" / follow sort. (please note numbers not sequential sequence 1,2,3... used example) 1,2,filename1 3,4,filename2 5,6,filename3 if sort first numerical column in descending order should this 5,6,filename3 3,4,filename2 1,2,filename1 how can go doing , still values of array individually? example: array(1,1) 5 , array(3,3) filename1 if want know, plan on creating playlist of wavfile names based on sort. ps: i'm using octave/matlab you can use 2 separate arrays, 1 2 columns of number , 1 strings. when sort first array based on first number, function return b

there wrong stack.h , i'm unsure missing. receiving segmentation fault error. know has "void pop()" , "t top()" functions. i'm pretty sure caused empty stack. editing these 2 functions, how can ensure program run? .cpp file needs have s2.pop outside of (!s2.empty) check. the answer should remove s2.pop() @ end. doesn't make sense there. while (!s2.empty()) { cout << s2.top(); s2.pop(); } // s2 empty now, pop() wouldn't make sense. cout << endl; s2.pop(); you change pop() function to void pop() { if (!empty()) container.pop_back(); } then pop() work on empty stack, top() still crash. can't fix top() easy either, you'd end different behaviours confusing , shouldn't have. or unintuitive implementations bad.

i have 1 class: public class prog3 { public static void main(string[] arg){ int k = 0, = 0; boolean r , t = true; r = (t & 0 < (i +=1)); r = (t && 0 < (i +=2)); r = (t | 0 < (k +=1)); r = (t || 0 < (k +=2)); system.out.println( i+ " " + k); } } why results of program are: 3 1 && , || short circuit operators, means: in && , if left side false , right side not evaluated. in || , if left side true , right side not evaluated. while & , | bitwise operators, means both sides evaluated. with @ hand, let's perform each operation: r = (t & 0 < (i +=1)); //true & +=1 -> = 1 r = (t && 0 < (i +=2)); //true && i+=2 -> = 3 r = (t | 0 < (k +=1)); //true | k +=1 -> k = 1 r = (t || 0 < (k +=2)); //true || ... no need evaluate right side

i'm trying replace plyr calls dplyr . there still few snags , 1 of them group_by function. imagine acts same way second ddply argument , split, apply , combine based on grouping variables list. doesn't appear case. here rather trivial example. let's define silly function mm <- function(x) return(x[1:5, ]) now can split species in iris dataset , apply function each piece. ddply(iris, .(species), mm) this works intended. however, when try same dplyr , doesn't work expected. iris %>% group_by(species) %>% mm what doing wrong? as shown in ?do , can refer group . in expression. following replicate ddply output: iris %>% group_by(species) %>% do(.[1:5, ]) # source: local data frame [15 x 5] # groups: species # # sepal.length sepal.width petal.length petal.width species # 1 5.1 3.5 1.4 0.2 setosa # 2 4.9 3.0 1.4 0.2 setosa # 3 4.7

i have div , hyperlink this: <div id="food-add-actions" class="actions food_dialog fd_food_dialog_s-fndds2-f41210000"> <div class="right"> <a href="javascript://" class="food-add-button add button"><span></span><span>add food log</span></a> <a href="javascript://" class="edit button"><span></span><span>edit</span></a> </div> </div> how can click on edit hyperlink? i tried below did not worked me driver.findelement(by.classname("edit button")).click(); the problem have have space in by.classname. there question similar problem here. webdriver classname space using java you should able select by.css selector, such as. by.css('.right a.button')

is possible add condition boost::signal . may boolean function , when emit signal should check if function returns true emit. i don't want check condition during emitting because emitted many places. don't want check condition in slot because should not know condition. if need emit signal many places way, add method it: void emitsignal() { if( /* condition */ ) { _signal(); } } then call emitsignal() instead of emitting signal directly.

i uploading data , image using ashx handler , working fine. but success function in ajax not getting executed see here: $.ajax({ type: "post", url: "../scripts/uploadify/uploadhandler.ashx", contenttype: false, processdata: false, data: imag, success: function(data){ console.log(data.bb); alert('hii'); } }); ashx: public void processrequest(httpcontext context) { httppostedfile postedfile = context.request.files[0]; if (!(postedfile == null)) { | | } context.response.contenttype = "application/json"; string bb = postedfile.filename; context.response.write(bb); //im getting bb name correctly suppose 'koyla.jpg' context.response.statuscode =

i have developed chat application using prosody , need send push notification when receives message , isn't online. this chat application works webapp written in ruby on rails. i searched lot , didn't found sends push notifications prosody(i found ejabberd had problems ejabberd). decided gem ror monitors directory, can monitor prosody's offline message directory , callback when message couldn't delivered user , send push notification him. i found gem listen guard( https://github.com/guard/listen ) need, don't know should start listener , when should stop since need run aways webapp online. you trying make over-complicated things, because think prosody "black box". in fact need: prosody module, "hooks" offline message , send webapp - see example here: https://github.com/jorgenphi/prosodypush push notification module favorite web framework - think can find tons of ruby gems it.
