i spotted proposed c# coding-standard stated "try offer interface abstract classes". know rationale this? the .net framework design guidelines have interesting things interfaces , abstract classes. in particular, note interfaces have major drawback of being less flexible classes when comes evolution of api. once ship interface, members fixed forever, , additions break compatibility existing types implement interface. whereas, shipping class offers more flexibility. members can added @ time, after initial version has shipped, long not abstract. existing derived classes can continue work unchanged. system.io.stream abstract class provided in framework given example. shipped without support timing out pending i/o operations, version 2.0 able add members supported feature, existing subclasses. thus, having corresponding interface each abstract base class provides few additional benefits. interface cannot publically exposed, or you're left @ square 1 in ter...

ok. i have class myclass , class based on list. let's call mycollection. now when types: mycollection coll = new mycollection(); ... coll.find(...) they acting on entire collection. want apply filtering - behind scenes - if write above code, actually executes like... coll.where(x=>x.canseethis).find(...) what need write in definition of mycollection class make work? can make work? you want write wrapper class implements ilist or icollection , using regular list internally. wrapper class proxy method calls internal list, applying filter required.

i want write high performance synchronized generator in c. want able feed events , have multiple threads able poll/read asynchronously, such threads never receive duplicates. i don't know how synchronization typically done. can give me high level explanation of 1 or more techniques might able use? thanks! the main concept in thread safety mutex (though there different kind of locks). used protect memory multiple accesses , race conditions. a example of use when using linked list . can't allow 2 different threads modify in same time. in example, possibly use linked-list create queue, , each thread consume data it. obviously there other synchronization mechanisms, 1 (by far ?) important. you have @ this page (and referenced pages @ bottom) more implementation details.

hi :) i'm trying write android application downloads bunch of images , afterwads displays them in gallery. managed download images (i did download them data/data/project directory - not sure if that's right) can't access them (i tried using setimageuri method of imageview display image after i've created uri instance via uri.builder().appendpath("data/data/project/file.jpg").build() no avail). i'm new android developing appreciated. thanks! i started writing example, decided waste of time since net littered better examples create. at high level, you'll need this: get 1..n file objects load bitmaps these objects using bitmapfactory load these decoded bitmaps imageview the typical mechanism viewing set of resources adapter pattern. mentioned, there example here encompasses use of asynctask , other patterns typical of android programming should become familiar with. review , see if have further questions.
