using localstorage, try store users configs, , works well. // in options_page localstorage.setitem('mykey',someval); but it's difficult read configs content_scripts (´･ω･`) localstorage.getitem('mykey'); // because different 'window' scope i'm making using runtime.sendmessage // in content_scripts chrome.runtime.sendmessage(null, {purpose:'getconfig',configkey:'mykey'}, function(confhere){ // action } ); i think it's complex!! (and using 'chrome.storage' requires permission, ugly) there way read configs content_scripts of chrome extension? content scripts run within context of pages sharing dom , not extension. so, content script trying read localstorage read localstorage of page, , not extension. the way proposed correct , far know best way access setting info in content script. so, when content script created send message background settings (as have done) , in background add list...

i have object. either long or string , simplify code let's assume that. i have create method tries convert object provided enum. so: public object toenum(type enumtype, object value) { if(enumtype.isenum) { if(enum.isdefined(enumtype, value)) { var val = enum.parse(enumtype, (string)value); return val; } } return null; } with strings works well. numbers causes problems, because default underlying type enum int , not long , isdefined throws argumentexception . of course can many checks, conversions or try-catches. what want have clean , small code that. ideas how make readable , simple? it feels me want handle 3 cases: input right type strings integers in various types i believe want valid input: public object toenum(type enumtype, object value) { if (value == null) { throw new argumentnullexception("value"); } if (enumtype == null) { throw...

i have db (access 2010) pulling data from, trying make easier pull specific cases instead of mucking in excel. we have 78 product type codes classify account type. unfortunately can't use in() function because there many characters (there 1024 char limit). looked online , suggested make table inner join on product codes want. i created table codes want pull, joined on productcodetype in linked database table. unfortunately when run sql nothing shows up, blank. tried different join combinations no avail, read further , found can't enforce referential integrity on linked db tables non-linked db tables. i think problem i'm not sure, , don't know if i'm using right language, can't find similar issue mine i'm hoping it's easy fix , i'm not thinking right way. is there way select cases (78 product type codes) large database using in() or reference table when can't create new table in linked db? thank you, k you must use 2 tables ...

i beginner in java programming. have code below socket socket = serversocketobj.accept(); bufferedwriter writer = new bufferedwriter(new outputstreamwriter(socket.getoutputstream())); try { writer.writeline(); } catch(ioexception e ) { //write logger here } { writer.close(); // throws ioexceptioin too. // possible memmory leak? socket.close(); } when try close writer should handle exception. don't know it. exception impossible in case? can ignore it? if don't know them, catch them , log them. simplest way of logging them e.printstacktrace() way, @ least you'll see there's problem if exception occurs. another approach re-throw exceptions upper-level code. e.g. if method (in sample code is) declares throw ioexception , there's nothing should worry about. let upper-level code worry it.
