i'm bit in doubt 'the right way'. i have application concepts visual studio, i'll use explain: i have 'solution' view model , model behind. view model displayed in 'explorer'. i can change between situations 'no solution loaded' 'a solution loaded' , back. and question :-) : should keep view model object , let reflect have new 'solution object' loaded? or should create new view model object , let view bind new object? thanks comments! (and merry christmas all!) anders, denmark your viewmodel contains state of data associated ui not further back in model. one way answer questions such yours considering behaviour want in ui , needs binding state information. or, put different way, time feel writing code cause ui elements shown or hidden, think how maps boolean variable. so, take large chunks of ui visible when have model loaded. these might have visibility bound boolean property in viewmodel issolut

a web-bot crawling site , using bandwdith resources. bots numerous , many purposes, starting homemade, university research, scrappers, new startups established search engines (and many more categories probably) apart large search engines can potentially send traffic site, why webmasters allow other bots purpose not know ? incentives webmasters allow these bots ? 2nd question is: should distributed crawler multiple crawlagent-nodes on internet, use different user-agent string each agent, because if use same ua, benefit of scaling via multiple agents highly reduced. because large websites high crawl-delay set, may take weeks or months crawl fully. 3rd question: since robots.txt (the defined crawl control method) @ domain level. should crawler have politeness policy per domain or per ip (sometimes many websites hosted on same ip) . how tackle such web poilteness problems ? other related things keep in mind ? there many useful bots besides search engine bots ,

hey guys moved macvim, it's great, when add theme: torth in .vimrc. found color vi totally changed, it's either way of rails plugin, or torth, mixed color. so how set startup color affect macvim, i'm familiar vi's color rails plug in, don't want mess up. btw how toggle off top tool bar in start up, great,if can show me find whole setup instruction. thanks macvim honors "gvim" settings. gvim being gnome vim gui variant rather prevalent on linux. this means should perhaps set overall settings specific user in "~/.vimrc", , override ones want in macvim defining them in "~/.gvimrc". it's decide organizational method suits best.

i'm newbie cryptographic area. here problem: i need decrypt cipher text(encrpyted rsa-public key) using privatekey in "privatekey.pem" format. not know has been encrypted whether password based or anyother methods, rsa based encryption. there way decrypt cipher text? hope understand query if doubts pls post me explain clearly. request post ways possible using java ... assymmetric encryption works on principle need 1 of 2 keys encrypt data , other 1 decrypt it. in case how work: generate key pair: 1 private key, 1 public key give public key else, have him/her encrypt message it. 1 can read message private key (no password involved). so thing need private key. this means need store private key somewhere. security reasons, private key encrypted triple des (which symmetric). in case, encrypt private key triple des password. after have decrypted private key, can use decrypt message encoded encoded public key.password , need password decrypt private key

i using nsxmlparser i fetch data server, parsing not end, because of spanish characters in data. how parse these spanish words? are sure encoding of document correct? encoding use? include encoding="utf-8" or such in <?xml ... ?> header? if xml parser doesn't know encoding, or encoding has been incorrectly specified, fail parse. if these encoded xml entities, entities hex-encoded, or named? if named, need included in dtd , you'll need call setshouldresolveexternalentities: yes .

im using listbox , adding objects it. the object contains 2 variables, lets username , userid. how can add objects in list listbox.items.add(object); , show username of object? thnx! you can use displaymember , valuemember properties display username property of object , use userid property list item value: class youritem { public string username { get; set; } public string userid { get; set; } } yourlistbox.displaymember = "username"; yourlistbox.valuemember = "userid"; yourlistbox.items.add(new youritem { username = "fooname", userid = "fooid" });

i edited question it still not work, user writes appendix press ok in login, nothing happens here login (vb.net) partial class login inherits system.web.ui.page protected sub button1_click(byval sender object, byval e system.eventargs) handles button1.click session("passcode") = textbox1.text response.redirect("default.aspx") end sub end class and here default page c# public partial class _default : system.web.ui.page { protected void page_load(object sender, eventargs e) { if (session["passcode"] == "appendix") { response.write("ok !"); } else { response.redirect("login.aspx"); } } } you mean session["passcode"] == "appendix" in c# (unlike vb), == equality operator , = assignment operator.

i'm trying come elegant recreation of search bar component in thunderbird . clear button doesn't appear until there text in box, screen-shot bit inaccurate. should use layered pane , buttons float above box? (but getting text not appear below buttons hacky) maybe put buttons @ ends of search bar , have somehow blend in? any ideas or maybe style reconsideration welcome, thank you. what white panel border , jtextfield without borders inside. 2 buttons (or more) in west , east. button appear/hide depending on text field content.

i have config-file global variables database connectivity settings (such db host, db name, user, pass). i able drag , drop files dev machine production server. however, development db host etc may different 1 on production server. is there easy way of, in php, saying "if i'm on dev-machine, use these values" ? (i'd prefer avoid hacks based on host ip / name.) i'm thinking of perhaps setting in php.ini or httpd.conf instance $dev_machine , set true on dev machine. you can set apache variable setenv , , query php's apache_getenv() .

we have business case need return both validation errors , warings server side , display on silverlight. see silverlight using system.componentmodel.dataannotations.validationresult process errors. not contain , fields "warnings". i wondering if has idea handle problem. thanks. i think validationresult used validationexception thrown subclasses of validationattribute. mecanism used blocking validation errors because throwing exception stops execution of code. if happens in service, exception can sent client , processessed, not wanted scenario. you extend model (those classes validationattribute, subclasses, validationexception not sealed) add warning flag you'd have trap exception continue processing , rethrow in case of warning. another alternative add business logic validation errors , warnings response client. approach because can include whatever info want way want/need it.

can somehow add paths dwoo looking templates from? have 2 folders store templates, , use extends -function across these 2 directories without having stuff "../templates/template.tpl" or using absolute paths. so, if in template {extends "base.htm"} i'd dwoo look, example, directories "/www/site/templates" , "/www/site/static" file. you can use includepaths function of dwoo_template_file class, example: $tpl = new dwoo_template_file('foo.html'); $tpl->setincludepath(array('/www/site/templates', '/www/site/static')); echo $dwoo->get($tpl, $data); then should automatically relative paths dirs , take first found.

i building application load list of news website. each news/headline has image. want save/cash images user not has download them again. q: in opinion, better/more sufficient way: loading images , saving them on device or use cachemanager? @ moment using first solution , works fine. however, website has many categories , more news per category therefore there lot of images saved on device. normal in type of applications save images on device? thanks help, marqs i don't think should save images on device, because of many reasons: why wasting device space on news images? user wants read news , thats it. (in case maybe open later, still - not forever) you can save on device , make app. delete files after lets 24 hours.. the main issue privacy issue, when user deleting cache files thinks webs visited has wiped device, in case aren't.. maybe can add "clean cache" button in app. after wrote think using cache-manager best way - because meant things ex
