i using vs 2008 sp1 , ie 8 beta 2. whenever start new web site or when double-click aspx in solution explorer, vs insists on attempting display aspx page in free-standing ie browser instance. address local file path aspx it's trying load , error says, "the xml page cannot displayed" shown. otherwise, things work work correctly (i close offending browser window. asp.net registered iis , have no other problems. have tested same configuration on other pcs , works fine. has had problem? thanks rp right click on file, select 'open with' , choose "web form editor" , click "set default".

i love way mac os beautifully renders fonts (not browsers). wondering if somehow same rendering in browsers running on windows? someone recommended sifr guess that's useful when need use non-standard fonts? check out gdi++/freetype ( link , link ). it's highly configurable font-rendering replacement windows. configuration of hinting, anti-aliasing, etc, should able approximate osx style font rendering close.

im having bit of trouble finding right xpath syntax check if particular node in xml exists. i'm allowed use xpath (so no xsl or else that, has pure xpath expression syntax). i have xml , has node filename doesn't exist in every case. when filename isn't specified, livecycle proces use different route fill in filename. how check if filename node exists? you can use count function - passing in path of nodes checking. if not exist, value of count 0: count(//filename) = 0

as know, magic quotes in php deprecated, done discourage relying on feature preventing sql injection , encourage developers develop database specific escaping mechanisms.[source: php.net] neccessary? if yes, why? why can't use functions mysql_real_escape_string() , addslashes() , stripslashes() achieve same thing instead of developing different escaping mechanisms? an answer example appreciated. thanks mysql_real_escape_string() database specific escaping mechanism :) if choosing database layer new project, sure take @ pdo prepared statements automatically take care of necessary escaping.

i there face recognition sdk/library available 1 can use in android ? whenever search on google came across recognizr , has idea sdk or helps developer in developing face recognition application are looking face detection (find face in photo) or face recognition (identify face in photo)? facedetection.com has decent list of opensource , commercial software detection and/or recognition. for face recognition, here's found on sourceforge: http://sites.google.com/site/elsamuko/c-cpp/opencv-facerecog https://github.com/b051/facereco (moved facereco.com redirects sketchy, unrelated site) then there commercial offerings: http://www.betaface.com http://www.ayonix.com/ http://www.cognitec-systems.de when googling keeps handing result don't want (e.g., recognizr), trick add term search leading minus ( -recognizr ) negate term.

i've been working on android sdk platform, , little unclear how save application's state. given minor re-tooling of 'hello, android' example: package com.android.hello; import android.app.activity; import android.os.bundle; import android.widget.textview; public class helloandroid extends activity { private textview mtextview = null; /** called when activity first created. */ @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); mtextview = new textview(this); if (savedinstancestate == null) { mtextview.settext("welcome helloandroid!"); } else { mtextview.settext("welcome back."); } setcontentview(mtextview); } } i thought enough simplest case, responds first message, no matter how navigate away app. i'm sure solution simple overriding onpause or that, i've been poking away in documentation 30 minutes or , haven't found obvious. ...

i want make login system using asp.net (mvc). on internet, found bad examples involved sql in click events. other information pointed asp.net built-in membership provider. however, want roll own. don't want use built-in membership provider, seems work on ms sql, , don't idea of having few foreign tables in database. i think of something, need few pointers in right direction. not have high-security, regular common-sense security. and have few direct questions: a lot of systems seem have session id stored in user table. guess tie session user prevent hijacking. check every time user enters page? , do if session expires? hashing, salting, do? know of md5 hashing , have used before. not salting. best practices cookies? i dont know best practices can tell do. not hitech security job. i use forms authentication. receive password secured ssl via textbox on login page. take password , hash it. (hashing 1 way encryption, can hash code cant reversed password)...

i've switched computers few times recently, , somewhere along way lost .emacs. i'm trying build again, while i'm @ it, thought i'd pick other configurations other people use. so, if use emacs, what's in your .emacs? mine pretty barren right now, containing only: global font-lock-mode! (global-font-lock-mode 1) my personal preferences respect indentation, tabs, , spaces. use cperl-mode instead of perl-mode. a shortcut compilation. what think useful? use ultimate dotfiles site . add '.emacs' here. read '.emacs' of others.

as java developer reading apple's objective-c 2.0 documentation: wonder " sending message nil " means - let alone how useful. taking excerpt documentation: there several patterns in cocoa take advantage of fact. value returned message nil may valid: if method returns object, pointer type, integer scalar of size less or equal sizeof(void*), float, double, long double, or long long, message sent nil returns 0. if method returns struct, defined mac os x abi function call guide returned in registers, message sent nil returns 0.0 every field in data structure. other struct data types not filled zeros. if method returns other aforementioned value types return value of message sent nil undefined. has java rendered brain incapable of grokking explanation above? or there missing make clear glass? i idea of messages/receivers in objective-c, confused receiver happens nil . well, think can described using contriv...

i happened debate friend during college days whether advanced mathematics necessary veteran programmer. used argue fiercely against that. said programmers need basic mathematical knowledge high school or fresh year college math, no more no less, , of programming tasks can achieved without need advanced math. argued, however, algorithms fundamental & must-have asset programmers. my stance computer science advances depended solely on mathematics advances, , therefore thorough knowledge in mathematics programmers when they're working real-world challenging problems. i still cannot settle on side of arguments correct. tell stance, own experience? to answer question posed have say, "no, mathematics not necessary programming". however, other people have suggested in thread, believe there correlation between understanding mathematics , being able "think algorithmically". is, able think abstractly quantity, processes, relationships , proof. i star...

i need this , collection of elements contains no duplicates of element. common lisp, sbcl, have thing this? for quick solution, use hash tables, has been mentioned before. however, if prefer more principled approach, can take @ fset , “a functional set-theoretic collections library”. among others, contains classes , operations sets , bags. (edit:) cleanest way define set-oriented operations generic functions. set of generic functions equivalent java interface, after all. can implement methods on standard hash-table class first prototype , allow other implementations well.

i've been looking answer how use bswap lower 32-bit sub-register of 64-bit register. example, 0x0123456789abcdef inside rax register, , want change 0x01234567efcdab89 single instruction (because of performance). so tried following inline function: #define bswap(t) { \ __asm__ __volatile__ ( \ "bswap %k0" \ : "=q" (t) \ : "q" (t)); \ } and result 0x00000000efcdab89 . don't understand why compiler acts this. know efficient solution? ah, yes, understand problem now: the x86-64 processors implicitly zero-extend 32-bit registers 64-bit when doing 32-bit operations (on %eax, %ebx, etc). maintain compatibility legacy code expects 32-bit semantics these registers, understand it. so i'm afraid there no way ror on lower 32 bits of 64-bit register. you'll have use series of several instructions...

i need convert punycode niato-otabd nñiñatoñ . i found a text converter in javascript other day, punycode conversion doesn't work if there's dash in middle. any suggestion fix "dash" issue? i took time create punycode below. it based on c code in rfc 3492. use domain names have remove/add xn-- from/to input/output to/from decode/encode. the utf16-class necessary convert javascripts internal character representation unicode , back. there toascii , tounicode functions make easier convert between puny-coded idn , ascii. //javascript punycode converter derived example in rfc3492. //this implementation created some@domain.name , released public domain var punycode = new function punycode() { // object converts , puny-code used in idn // // punycode.toascii ( domain ) // // returns puny coded representation of "domain". // converts part of domain name // has non ascii characters. i.e. dosent matter if /...
