doing rapid prototyping app running in browser , on ios/android/etc. @ point may have build native versions, not necessary @ moment. we need native push notifications working @ least on ios (which isn't supported browser, may getting worked on future release supports progressive web apps). looking cleanest solution issue still allows keep our single code base , won't bloat our working environment. from cursory investigation looks reactnative require device specific branching. may fine down road, wait until through of our initial prototyping. is phonegap/cordova way go? speed on device isn't big issue keeping our code base clean can move fact it's in webview doesn't matter much. haven't touched phonegap in ages, can isolate code base cleanly wrapper? another option thinking of writing lightweight ios wrapper webview , basic bindings handle push notification aspect. not sure if tricky though, , may have hidden pitfalls. would love recommendations c

i use nginx on ubuntu forward requests spring boot -driven api server. api returns body 4xx , 5xx errors, client application consumes. e.g. in api code might return: { "message": "blah" } however nginx seems wrap errors html , embeds response within them. there way disable behavior? , there way en masse (i.e. 4xx , 5xx errors, without explicitly writing them out error_page example) similar question , accepted answer here , seems bit of hack. i'm sure there's better way of doing this... edit: config looks this: server { listen 80; server_name my.domain.com; location / { proxy_pass http://127.0.0.1:9001; } } you need add error_page directive inside location server { listen 80; server_name my.domain.com; location / { error_page 404 = 404; proxy_pass http://127.0.0.1:9001; } } what cancel error_page previous directives set @ http block. , pass result client is.

i'm working swift 3. i have c syntax : int myvar; int *pointer = &myvar; so modifying pointer or myvar same exact same thing. don't know if makes difference, in case myvar array containing elements of class , pointer pointer 1 element of array. (assuming understand you're asking for....) try following code in playground. should print "99" 3 times. class row { var rownumber = 0 } var rows = [row]() let testrow = row() testrow.rownumber = 1 rows.append(testrow) let selectedrow = rows[0] selectedrow.rownumber = 99 print(testrow.rownumber) print(selectedrow.rownumber) print(rows[0].rownumber) by default, there's no copying of objects part of assignment statement. if struct, different. adding bit completeness: if want similar effect scalar values instead of objects, swift supplies various types of wrappers. let intpointer = unsafemutablepointer<int>.allocate(capacity: 8) // should 1, not 8 according comment

i had problem quite while. what planned if of cell[0] has value, trigger event. if there null , it'll change value of textbox . here's code: private void button1_click(object sender, eventargs e) { (int = 0; < datagridview1.rows.count; i++) { if (datagridview1.rows[i].cells[0].value.tostring() == null) { textbox.text = "null"; break; } else { messagebox.show("no null"); } } but whats happening here example have 3 rows in datagridview , if first row not null lunch messagebox . want messagebox triggered when of row's cells not null. try this: bool anynull = false; (int = 0; i<datagridview1.rows.count; i++) { if (datagridview1.rows[i].cells[0].value.tostring() == null) { textbox.text = "null"; anynull = true; break; } } if (!anynull) messagebox.show("");

i have rewrite rule product detail page instead of url being /product-detail.php?id=3765 it instead: /blue-jeans this rewrite rule: rewriterule ^([0-9a-za-z-]+)$ product-detail.php?slug=$1 [nc,l] however, need 1 regional dealers. add .htaccess, product detail rule stops working in blank page displayed when navigating product. how can them both work? rewriterule ^([0-9a-za-z-]+)$ dealers.php?slug=$1 [nc,l] it's because matching regex identical, , first 1 of them matches , you're done. need wrapping php script can sort out or have other token in regex limit scope. example products under /products , dealers under /dealers, , like: rewriterule ^/dealers/([0-9a-za-z-]+)$ /dealers.php?slug=$1 [nc,l] rewriterule ^/products/([0-9a-za-z-]+)$ /products.php?slug=$1 [nc,l]

i started learning java , having difficulty understanding classes. 1 of recent assignments create class called triangle - given user input main method - take in input test if input see if hypothetical "triangle" equilateral, isosceles, or scalene , return main. able program work not 100% within guidelines of assignment's requirements (which specified having 2 additional methods calculated largest , smallest side-length). wondering, after fact, if can @ did , let me know if can see , or explain - in beginner terms - why having 2 methods needed if works without them (i.e. program somehow @ disadvantage nature of not having them) , if so, doing wrong kept throwing errors when tried implement methods? i'll include both assignment guidelines (for reference since not assume mind reader) , code: "your assignment write class definition (not program, there no main method) named triangle (saved in file triangle.java). triangle has 3 instance variables: int side1, s

i have post method, request input list of newlink objects (newlink attributes linkurl , status) using async.map iterating on urls check if links active or not. newlinks contains links {www.google.com,www.nourl.com,www.xyz.com} expecting after request processed , setting corresponding status true or false, want send using res.send(newlinks) but console giving below results: "www.google.com up", calling res.send(), executing "www.nourl.com up" , "www.xyz.com up" so here, after first url request , code below executing function outside async loop. thought async allow next piece of code execute after urls validated. app.post('/myposturl', function(req , res){ var request = require('request'); let linkdetails= req.body.linkdetails; var = 0; async.map(linkdetails, function(newlink, callback) { var url = "url"; var url = newlink.linkurl; var proxiedrequest = request.defaults({'proxy': url}); proxiedreq

smart tags appear controls on form, not actual form itself. looking @ link (walkthrough: adding smart tags windows forms component) https://msdn.microsoft.com/en-us/library/ms171829.aspx it seems overly cumbersome have modify code surely setting somewhere? have missed something? i haven't put code against of controls on form (listbox, combobox etc.) , display smart tags , action lists little arrows perfectly. thanks i resolved adding 'form assistant' component project.

here code, trying convert data wide format may or may not have duplicate data. tried use for-each , parallel still takes more time, can suggest change this data processing:- param1: 1, , 753360af0c8949c0aeab64d520599656 param2: value2 param3: value3 param4: value4 param1: 2, , 8c8c659813d842c5bab2ddba9483ea5a param2: value5 param4: value6 param3: value7 so need wide format the above example contains 4 parameters. file can have 10 varying number of parameters text file comes different sources. the result should this:- param1 param2 param3 param4 1 753360af0c8949c0aeab64d520599656 value2 value3 value4 2 8c8c659813d842c5bab2ddba9483ea5a value5 value6 value7 here code same:- f <- read.table("./sample.txt",header = false, sep = ":",fill=true, row.names=null) f[,2] <- paste(f[,2],f[,3],f[,4]) c <- unique(f[,1]) rw <- round(nrow(f) / length(c)) + 1 result <- data.frame(matr

i have line plot , 2 hlines, using different colors, , i'm filling areas main line crosses hlines color of hline. in addition that, i'd use same color main line in areas. in nutshell, current output: desired output: and relevant code i'm using: lower, upper = 20, 80 self.indicatorplot.axhline(lower, color="red") self.indicatorplot.axhline(upper, color="green") self.indicatorplot.plot(self.charttimes, self.indicatordata, color="blue") self.indicatorplot.fill_between(self.charttimes, self.indicatordata, lower, where=(self.indicatordata <= lower), facecolor="red", interpolate=true) self.indicatorplot.fill_between(self.charttimes, self.indicatordata, upper, where=(self.indicatordata >= upper), facecolor="green", interpolate=true) in principle may split plot 3 parts, values above upper , values below lower , values in middle. in sense question has been asked , answered, e.g. python: possible chang
