this question has answer here: how formatted json in .net using c#? 6 answers basically dupe of this question 1 notable difference - have use datacontractjsonserializer . a simple using (var stream = new memorystream()) { var serializer = new datacontractjsonserializer(typeof(person)); serializer.writeobject(stream, obj); ... return stream.toarray(); } produced single line json, e.g. (when saved in file) ...{"blah":"v", "blah2":"v2"}... what options make it ... { "blah":"v", "blah2":"v2" } ... i can think of post-processing... there easier option? e.g. similar formatting xml produced datacontractserializer ? using (var stream = new memorystream()) { var serializer = new datacontractjsonserializer(typeof(t)); // "beautify" us

i'm trying run ./swift -emit-executable shape.swift terminal shape.swift class shape { let name:string = "" init(name:string) { self.name = name } let anyshape = shape.init(name:"jaum") println("name, \(anyshape.name).") } i'm getting error: shape.swift:11:5: error: expected declaration println("name, \(anyshape.name).") ^ what doing wrong? you can't have declarations @ root level of class, move them outside. don't use .init create class instance. use print instead of println (it has changed in swift 2 ). and don't give value of "" immutable name if want use initializer, declare type. class shape { let name:string init(name:string) { self.name = name } } let anyshape = shape(name:"jaum") print("name, \(anyshape.name).") last note, it's not swift swiftc able create executable: swiftc -e

in developer.android.com site saw below information under android 6.0 changes. apache http client removal android 6.0 release removes support apache http client. if app using client , targets android 2.3 (api level 9) or higher, use httpurlconnection class instead. api more efficient because reduces network use through transparent compression , response caching, , minimizes power consumption. continue using apache http apis, must first declare following compile-time dependency in build.gradle file: android { uselibrary 'org.apache.http.legacy } problem: i using eclipse , have used http client. use new httpurlconnection how can add dependency in eclipse ide? or have use android studio use new feature? thanks looking , giving solution problem. @senthilkumar s should use android studio . uselibrary adds library classpath while compiling not bundle library application. courtesy @laalto sir . please upgrade gradle tools version in build.gradle f

a co-worker suggested use multiple hosts website authentication based on ldap in case 1 host down. know can $ldap_servers = "10.101.01.1 10.100.10.2"; $ldap = ldap_connect($ldap_servers); but i'm using config file: return [ 'domain_controller' => ['10.101.01.1', '10.100.10.2'], 'base_dn' => 'ou=foo,dc=example,dc=local', 'ssl' => false, ... ]; whereas connection done via $protocol = $this->ssl ? $this::protocol_ssl : $this::protocol; $port = $this->ssl ? $this::port_ssl : $this::port; return $this->connection = ldap_connect($protocol . $hostname, $port); as co-worker suggested might possible our ldap hosts run via ssl in future, how can make multiple hosts work this? above it's working hostname only, that's because it's non-ssl based. given ssl need ldaps:// protocol , portnumber, right? therefore not work hostname , i'm not sure

we have extjs 5.01 app built sencha cmd 5.0.1.231. the issue facing browsers seem cache old version of our application. on looking @ network traffic on chrome when our application served, can see app.js, app.css files have ?_dc={timestamp} appended them. now, tells me every time new version of app released (which updates timestamp), browsers should new version. seems still old version served. is there else need bust cache? thanks i don't why "sometimes" browser caching files, when caching disabled default. force framework use cache whenever possible, putting peace of code in app.js : ext.loader.setconfig({ enabled: true, disablecaching: false }); while developing open devtools , set disable cache (while devtools open) . not allow chrome cache files. but in app.json forcing "caching" local storage setting "update" or "appcache" . check localstorage , app.json verify.
