i'm wondering how go accessing same int variable between activity classes in android app. situation have variable represents number of points , i've placed in own class , want value same between every activity uses it. when user gets point, increases 1 let's user gets 12 points, want same throughout activity s. step 1: extend activity s common baseactivity class. step 2: put int variable in baseactivity , add protected , static qualifiers int variable: public class baseactivity extends activity{ .... .... protected static int points; .... .... } now can access points variable in every activity , have same value. there no need use singleton here other answers suggesting. simpler have common static variable. programming 101. try this. work.

i need copy image server in order create different types of images it, e.g. thumbnail. while works ok imagecreatefromjpeg($picture_location); create problem if image not available , take 30s timeout. therefore thought downloading first copy: copy('http://www.server.com/file.jpg', '/tmp/file.jpeg'); unfortunatelly there no way decrease timeout if connect fails or image has been removed. is there better way achieve intending? thank on this. you can download file via curl has timeout option. <?php $fp = fopen (dirname(__file__) . '/localfile.tmp', 'w+'); $ch = curl_init($url); curl_setopt($ch, curlopt_timeout, 50); //timeout curl_setopt($ch, curlopt_file, $fp); curl_setopt($ch, curlopt_followlocation, true); curl_exec($ch); curl_close($ch); fclose($fp); ?>

i wonder why following code works in c# 6.0: (in example data random class containing val public string) if ("x".equals(data.val?.tolower()) { } but following line isn't: if (data.val?.tolower().equals("x")) { } visual studio shows me following error: cannot implicitly convert type 'bool?' 'bool'. explicit conversion exists (are missing cast?) if ("x".equals(data.val?.tolower()) { } will return boolean because of equals call this: if (data.val?.tolower().equals("x")) { } when expression evaluated return system.nullable<bool> different bool (former struct can assigned value null while latter can true or false ) the if expects. also, in c# null value doesn't evaluate false (according c# specification).

here simple case: trying cast object type primitive this: object object = integer.valueof(1234); int result1 = int.class.cast(object); //throws classcastexception: cannot convert java.lang.integer int int result2 = (int)object; //works fine this source code of cast method of class 'class' public t cast(object obj) { if (obj != null && !isinstance(obj)) throw new classcastexception(cannotcastmsg(obj)); return (t) obj; } private string cannotcastmsg(object obj) { return "cannot cast " + obj.getclass().getname() + " " + getname(); } why happening? same happening other primitives too. live example cast can't work primitives, given can't return value of actual primitive type, due generics in java... end boxing again anyway. , if you're not assigning straight int value, have boxed reason too. so basically, if want convert int , cast directly. isinstance documented return false primitives: ...

i have implemented eclipse plug-in runs in test workbench, eclipse ide php developers , eclipse ide java developers doesn't work in eclipse cdt . there no error messages, dont't know, why. my plug-in adds popup menu entry , executes action. notices plug-in stops after line: ifile file = (ifile) ((istructuredselection) wbw.getselectionservice().getselection()).getfirstelement(); all ides run on kubuntu 14.04. the selection returned selection service user interface object rather ifile . need use iadaptermanager adapt object file. object selected = ((istructuredselection) wbw.getselectionservice().getselection()).getfirstelement(); iadaptermanager manager = platform.getadaptermanager(); ifile file = (ifile)manager.getadapter(selected, ifile.class);

i want make bitset in c++. did bit of research. examples found this: bitset<6> mybitset; // but don't know size of bitset when define variable in class: #include <bitset> class test { public: std::bitset *mybitset; } this won't compile... and initializing doesn't work: int size = getdependentsizeforbitset(); mybitset = new bitset<size>(); boost has dynamic_bitset can use. alternatively, can use vector<bool> , (unfortunately) specialized act bitset. causes lot of confusion, , in general considered bad idea. that's how works, if that's need, might use it, suppose.

i'm developing iis 7 managed module, distributed along server-side software. how can manage settings/configurations within iis module itself? example, how can let user set api-key internally used module? i know in apache or in nginx can add settings directly in virtualhosts file (apache) , in nginx configuration files (nginx). wonder if there "best practice" iis modules. yes there is, can use web.config files that, optionally define own configuration section, depending on how complex configuration is, maybe using existing appsettings section enough. module can read appsettings like: how read appsettings section in web.config file? and best thing includes built-in ux in iis manager manage application settings. bad part not give validation customers, nor "intellisense" guide them through configuration. if want define own section can at: http://www.iis.net/learn/develop/extending-iis-configuration/extending-iis-schema-and-accessing-the-custom-s...

i working on project has dozens of forms. : laptops_form | mobile_form | vehicles_form | form_45 . for each form data stored in different table in database. i have 45 forms. vast e-commerce web application. each database table has representational page in application visitors see posted ads. i intermediate level programmer. in scenario feel it's way it. right or there way achieve such goal in minimized way. it depends on type of data stored in tables, if, example, data fields similar need differentiate between forms, can create 1 table , add flag called form_type, , table store data forms. if data fields different, can have (like have right now) table each form, or can have few dynamic tables (like when you're building custom form). personally, favor approach because it's faster when comes performance. second approach, however, more flexible , you'll able add more forms if want without creating additional tables - additionally, reporting easi...
