Core code

i'm not able give question apt title apology that. making modularised application. load various jar files @ runtime , invoke particular method of particular class (of jar file) @ run time. the jar file has supported file. jar file uses application , lets abc located in same directory have kept jar file. when run jar file new file(".").getabsolutepath() gives correct path (this abc located) , program runs fine. when load jar file dynamically , invoke method using reflection above code gives path of parent program , abc not found @ path. now question how find path in jar file exists when i'm running jar file's code using reflection. please let me know if need more explanation. try this: public static void main(string[] args) { system.out.println(stringutils.class.getresource("stringutils.class")); } (note: stringutils present on classpath maven dependency @ time) gives me: jar:file:/home/******/.m2/repository/org/apach...

i'm using promise result fill data source , update table view data. i have declared: var tdatasource: [friendresponser]? //contains de result previous bind var datasource: [friendresponser]? { //this total result after append didset { self.tableview.reloaddata() } } but, when try append result with: promise.then { user in self.tdatasource = user datasource?.append(tdatasource?) //self.datasource = user }.catch{ error in sclalertview().showerror("error", subtitle: error.localizeddescription) } but in datasource?.append(tdatasource?) giving me error: _?? not convertible '0' how can append result data datasource display both results? use extend append appends 1 element of same type extend appends array of same type

sometimes width of column containing inline edit buttons small. width cannot changed mouse. for example, open demo from http://www.ok-soft-gmbh.com/jqgrid/ok/removepagehorizontalscrollbar2.htm and try resize actions or number column dragging right border in header. column width not change. how fix actions , number column widths can changed user ? the referenced example contains column defined as { name: "act", template: "actions", width: 66 } the width of act column fixed , 66px . template actions defined following (see the line of code): actions: function () { return { formatter: "actions", width: (this.p != null && this.p.fontawesomeicons ? 33 : 37) + (jgrid.cellwidth() ? 5 : 0), align: "center", label: "", autoresizable: false, frozen: true, fixed: true, hidedlg: true, resizable: false, sortable: false, s...

i'd create generic find() typically used in functional programming. in functional programming don't work array indices , loops. filter. way works if have list of ["apple", "banana", "cherry"] and want find banana assign array indices list elements creating tuples [(1, "apple"), (2, "banana"), (3, "cherry")] now can filter down "banana" , return index value. i trying create generic function error. what's wrong syntax? func findingenericindexedlist<t>(indexedlist: [(index: int, value: t)], element: (index: int, value: t)) -> int? { let found = indexedlist.filter { // error: cannot invoke 'filter' argument list of type '((_) -> _)' element.value === $0.value } if let definitefound = found.first { return definitefound.index } return nil } update 1 : use above solution opposed using find() (will deprecated) or in sw...

in 1 of tests want perform before :all action, , need want test method not called in before :all action. there way this? e.g. want able to: before :all @bar_called = false # set @bar_called true if bar called on instance of class foo do_other_stuff end and then, in 1 of specs later on, expect @bar_called == false you implement mock block, set @bar_called . expect(obj).to receive(:my_method) { @bar_called = true } now, may want consider setting expectation on mock/stub instead expect(obj).to receive(:my_method).exactly(0).times see rspec-mocks documentation on receive counts .

what want behavior: class a: list=[] y=a() x=a() x.list.append(1) y.list.append(2) x.list.append(3) y.list.append(4) print x.list [1,3] print y.list [2,4] of course, happens when print is: print x.list [1,2,3,4] print y.list [1,2,3,4] clearly sharing data in class a . how separate instances achieve behavior desire? you want this: class a: def __init__(self): self.list = [] declaring variables inside class declaration makes them "class" members , not instance members. declaring them inside __init__ method makes sure new instance of members created alongside every new instance of object, behavior you're looking for.

i'm curious know, because i'm still learning layout pages, if when use layout page (ex. sitelayout.cshtml) , have 2 pages getting rendered (index.cshtml, results.cshtml) in @renderbody() section, layout wrapper part loaded each time go between index.cshtml , results.cshtml? or _layout.cshtml page load @renderbody() section asynchronously? just throw in example pics unless you've setup donut caching ( http://weblogs.asp.net/scottgu/tip-trick-implement-donut-caching-with-the-asp-net-2-0-output-cache-substitution-feature ), sitelayout.cshtml executed separately every page. if sitelayout has long/expensive operation , don't want loading every time, can use aforementioned donut caching have execute once per user per x amount of time. if want sitelayout start sending data browser before body done executing/rendering (i.e. asynchronously overall speed purposes), can use nuget package called courtesyflush ( http://www.hanselman.com/blog/nugetpackageofth...

i working on vertx.io application , wanted use provide mongo api data storage. have rather clunky abstraction on top of stock jsonobject classes get , set methods replaced things like: this.backingobject.get(key_for_this_property); this , now, won't scale particularly well. seems dirty, when using nested arrays or objects. example, if want able fill fields when actual data known, have check if array exists, , if doesn't create , store in object. can add element list. example: if (this.backingobject.getjsonarray(key_list) == null) { this.backingobject.put(key_list, new jsonarray()); } this.backingobject.getjsonarray(key_list).add(p.getbackingobject()); i have thought potential solutions don't particularly of them. namely, could use gson or similar library annotation support handle loading object purposes of manipulating data in code, , using serialize , unserialize function of both gson , vertx convert between formats (vertx load data -> json st...

i have framgments called in order fragone calls fragtest , fragtest calls fragbook. when current fragment fragbook on pressing button, fragtest shown split second , app sent app tray. @override public boolean onkeydown(int keycode, keyevent event) { fragmentmanager fragmanager = getsupportfragmentmanager(); fragment frag = fragmanager.findfragmentbytag("frag_book"); if ((keycode == keyevent.keycode_back)) { if (frag.isvisible()) { fragmanager.begintransaction() .replace(r.id.container, fragment.instantiate(mainactivity.this, fragments[1]),"frag_test") .commit(); } } return super.onkeydown(keycode, event); } where have gone wrong in approach? thanks... @override public boolean onkeydown(int keycode, keyevent event) { fragmentmanager fragmanager = getsupportfragmentmanager(); fragment frag = fragmanager.findfragmentbytag("frag_book...

so have search on 3 fields. age , sex , ethnicity if age given have return records matching age. if age , ethnicity given sex empty return matching records age , ethnicity. etc.. the naive way of solving this: class profile def self.search_profile(search_params_array) if search_params_array.first != nil && search_params_array.second != null && search_params_array.third != null profile.where("age = ?", search_params_array.first).where("sex = ?", search_params_array.second).where("ethnicity = ?", search_params_array.third) end ... ... # can permutate between possible conditions 1 of element nil ... end end what better way approach this? class profile def self.search_profile(search_params_array) params = %w(age sex ethnicity).zip(search_params_array).reject |_, v| v.nil? end.to_h where(params) end end if can pass search params hash, things can easier.

if create usercontrol , drag form, double click on it, create sub: private sub myusercontrol_load(sender object, e eventargs) handles myusercontrol.load end sub is possible change default handler? example produce on click handler: private sub myusercontrol_click(sender object, e eventargs) handles myusercontrol.click end sub you'd have create own class this... little waste of time really, since you'd have add code inherit custom class every time create new usercontrol. but if you're interested in testing it: <defaultevent("click")> _ public class myusercontrol inherits usercontrol end class then put in every usercontrol create (below public class line): inherits myusercontrol note error on inherits myusercontrol line. if so, apply fix says "change [class name] inherit myusercontrol." hope helps!
