i want include custom html in shopify theme whenever user install / enable app in store. can suggest me how ? using asset api can add or update assets, example custom html. asset belongs theme, need theme api , gives access installed theme(s) , it's role(s). shouldn't update existing assets don't belong own app. if want add javascript store, might want use scripttag . a third option use application proxies . application proxies forward web requests application. application returns custom html (or liquid), returned visitor. way extend store example image gallery. keep in mind assets won't removed when store uninstalls app. after uninstall don't have access assets anymore. scripttag removed when store uninstalls app. application proxy can implement access mechanism , deny access when store uninstalls app.

currently debugging code , not know reason classes not allow me put breakpoints , have sources files... does has ever had problem? when try put breakpoint in variable, puts breakpoint in name of class. here share link image: http://tinypic.com/view.php?pic=s4q3p2&s=8#.uzbhq6zge3q thank you!

glenable (gl_blend); glblendfunc (gl_src_alpha, gl_one_minus_src_alpha); and used in fragment shader. i've used alpha blend transparency working seems work 1 side. not sure problem is, new programming , shading. http://imgur.com/wdk4qjc link see picture i think see 2 distant faces blending color darker. maybe culling not activated. face culling ability discard face drawing upon condition. to achieve want, have discard faces not facing camera call backface culling . this: glenablegl(gl_cull_face); //(enable face culling) glcullface(gl_back); //(discard faces)

i want use ef , know 2 way use context accessing data methods of class: 1.passing connection each method of class: public partial class myentity { public static int add(myentityconnection context,myentity input) { context.myentity.addobject(input); context.savechanges(); return input.id; } } 2.using context on each method independently: public partial class myentity { public static int add(myentity input) { using (var context = new myentityconnection()) { context.myentity.addobject(input); context.savechanges(); return input.id; } } } which of above or other ways better? i'd recommend context per request per walther's comment, use dependency injection , repository pattern manage lifetime. something like: how-to inject entity framework dbcontext configurationbasedrepository of sharprepository

consider have data copied clip board. variable( not in way of pasting on terminal window ),so can able make use of variable. can 1 suggest way of doing it.either using script execution or using class or etc. maybe give more information application: web/zen/csp, tui, other types. anyway, cache, not have special variables clipboard.

attoparsec provides function takewhile1 consumes @ least 1 character. however, there no analog skipwhile . how can implement function skipwhile1 ? note: question intentionally shows no research effort answered q&a-style. another possible implementation: import control.applicative skipwhile1 p = skip p *> skipwhile p this might faster @uli's answer because takewhile builds result string, whereas skipwhile doesn't. laziness might make them equivalent (ie. maybe takewhile doesn't build string if don't use it); can't test @ moment verify this.

i working on project , got point when had write first script. when wrote it, every other script in unity stopped working. it says "the associated script cannot loaded, please fix compile errors , assign valid script.". i have not edited of other scripts, should work , when import them in project work. can't start on because have put weeks worth of work , if start on won't guarantee won't happen again. here script #pragma strict function start () { private var doorisopen:boolean=false; private var doortimer:float=0.0; private var currentdoor:gameobject; public var dooropentime:float=3.0; public var dooropensound:audioclip; public var doorshutsound:audioclip; } function update () { if(dooropen){ doortimer+=time.deltatime; if(doortimer>dooropentime){ door(doorshutsound,false,"doorshut",currentdoor); } doortimer = 0.0; } } } function door(aclip : audioclip ,...
