i refactoring existing code. i've extracted interfaces existing classes. have created separate class library holds such interfaces. problem have classes structures , enums. these classes have methods returning these structures , enums. i want extract interface these class. worried structures , enums. can't have these structures , enums extracted in interface , hence methods returning structure , enums not reflect in extraction. how can overcome situation wherein want have structure , enums in extracted interface? need break structure , have use members of interface? how can define methods returning structure in interface? structures , enums shouldn't nested- unlike classes, part of 'public contract' of type, , you'd typically extract them own files , put them in shared class library interfaces.

with phpexcel , i'm using: $worksheet->fromarray($array) ; to set data. however, 1 column needs set string (a number leading zero, leading 0 gets cut off if not set string). if wasn't using fromarray method, set data type using phpexcel_worksheet::setcellvalueexplicit() . however, want using range of columns. ideally this: $worksheet->getcell('a1:a50')->setdatatype(phpexcel_cell_datatype::type_string); but looking @ code, getcell won't allow range, single cell. how can this? there no method in phpexcel allow set data type range of cells, individual cell. there couple of options... harder write custom cell value binder automatically sets data type cells string when cell value set fromarray(). what instead (and far easier), leave datatype number, , value numeric, set number format mask tells excel display numbers leading zeroes. $objphpexcel->getactivesheet()->getstyle('l3:n2048') ->

hey there, i'm little confused actionscript i'm working on. gui, have written 4 functions times when computing taking place. these showmessage("loading text..."), disablebuttons(), clearmessage(), , enablebuttons(). work great throughout program. showmessage displays loading message, disablebuttons disables buttons no 1 can click anything, clearmessage clears loading message when job done, , enablebuttons turns them on. for reason, there 1 button click handler giving me troubles , i'm not sure why. i've set others similar (which work) 1 doesn't display message or shut off buttons. here clickhandler... private function buffer_route_clickhandler():void { showmessage("loading rbe options"); disablebuttons(); if(buffer_route.selected && rbeac.length == 0){ createrbeac(); } } and here creatrbeac function... private function createrbeac():void {

i developed iphone app in xcode 3.2.5. know version of xcode comes sdk 4.2. while testing app, set active executable ipad simulator 3.2., when executable run, 1 of views in app in blank (white), uinavigationcontroller nav bar still visible though. this blank view happens 1 loaded nib file, other (working) views programmatically generated. i set ios deployment target ios 3.2 in build settings. is there reason problem? view simple, few buttons, labels , uiwebview. edit: view constructed in ib. fwiw there handful of images in view also update: i've since run app on devices (ipad 4.2 & iphone 3.1) same problem, particular view appears white. in response comments; in ib set file's owner's class view controller set viewcontroller's view root view (in case uiscrollview) connecting 'dot' uiscrollview. i don't have init method view controller, below viewdidload method. - (void)viewdidload{ [super viewdidload]; uibarbuttonitem *addbutton = [[u

i'm creating little web app people can choose colors different parts of race car. i'm using imagemagick take separate images of each part of car, recolor them (with clutimage function), , layer them on top of each other create final image. each image png-24 alpha transparency. each image same size make easier combine them. there ten layers, 6 of being recolored. problem performance bit poor; takes ten seconds render image after each color change. here's code: sample code: <?php if(isset($piece['color'])) { //make 1pixel image replace color $clut = new imagick(); $clut->newimage(1, 1, new imagickpixel("#".$piece["color"])); //change color of part $car_part->clutimage($clut); } //now need add part onto car $car->compositeimage($car_part, imagick::composite_default, 0, 0); clutimage seems might overkill task; i'm not doing gradient map, i'm replacing colored pixels solid color. yet

in project (asp.net mvc + nhibernate) have entities, lets document s, described set of custom metadata. metadata contained in structure can have multiple tags, categories etc. these terms have importance users seeking document want, has impact on views underlying data structures, database querying etc. from view side of application, interests me string values terms. ideally operate directly on collections of strings that: class metadataasseeninviews { public ilist<string> categories; public ilist<string> tags; // etc. } from model perspective, use same structure, simplest-possible orm mapping , use in queries "fetch documents metadata this". but kind of structure turn out useless if application needs perform complex database queries "fetch documents, at least one of categories in (cat1, cat2, ..., catn) or @ least one of tags in (tag1, ..., tagn) ". in case, performance reasons, use numeric keys categories , tags. so 1 can im

i looking introduction python namespaces. found this tutorial good, i'm sure there more story that. the python reference contains information it's quite hard read. please explain python namespaces. in explanation please include complete examples show various uses. they're not complex. import mechanisms can complex , relative imports can bit more tricky, far actual namespaces , how they're resolved in code, tutorial seems pretty comprehensive. the language reference kind of be-all, end-all however, it's overkill starting out. if have specific questions how things work, you'll responses on here.

my problem pretty easy understand. have json object (see code) , automatically call functions of object in order appears. . var installer = { : function() { ... } b : function() { ... } }; for(var func in installer) { fn.call(document); }; have idea why previous code doesn't work ? i'm sorry, i'm beginner in javascript. thanks in advance ! regards. you declare var func variable loop through members of installer , yet use fn.call(...) . did fn come from? should able do: installer[func].call(document) instead of fn.call(document) . also functions declared in installer object don't take arguments, yet you're passing document argument. [updated code add missing .call installer[func](document) ]

how append portion of byte array stringbuilder object under java? have segment of function reads inputstream byte array. want append whatever read stringbuilder object: byte[] buffer = new byte[4096]; inputstream is; // //some setup code // while (is.available() > 0) { int len = is.read(buffer); //i want append buffer[0] buffer[len] stringbuilder @ point } you should not use stringbuilder this, since can cause encoding errors variable-width encodings. can use java.io.bytearrayoutputstream instead, , convert string when data has been read: byte[] buffer = new byte[4096]; bytearrayoutputstream out = new bytearrayoutputstream(); inputstream is; // //some setup code // while (is.available() > 0) { int len = is.read(buffer); out.write(buffer, 0, len); } string result = out.tostring("utf-8"); // instance if encoding known not contain multi-byte sequences (you working ascii data, instance), using stringbuilder work.
