i looking setting td length value 4 1 condition set length 11 other condition. since cant access javascript values in jsp, not thinking set flag in javascript function thought of using hidden parameter concept access, since using btt framework doesnot suport feature. feature eliminated then there other way in javascript can control display of td or tr based on condition some thing 2 td based row <tr> <td> </td> (display if condition true) <td length=4> </td> (display if condition false) <td length=11> </td> </tr> <tr> <td> </td> <td> </td> </tr> just let jsp print java side variable if javascript variable. <script>var width = ${width};</script> imagine jsp ${width} prints 11 , generated output follows in webbrowser: <script>var width = 11;</script> that's it. can use in js functions.

the problem is: service send me data every 1 hour , need start activity1. if nothing, time create same activity1 , in 5 hours in stack have 5 same activities...so, how kill activity before new 1 start ? ! intent dialogintent = new intent(getbasecontext(), someclass.class); getapplication().startactivity(dialogintent); so, how kill activity before new 1 start ? you don't. first, users attack hunting knives popping activity in middle of nowhere. not know may in middle of doing (playing game, typing text message, etc.). few apps, such voip clients , alarm clocks, should displaying activities except based upon direct user input. second, don't "kill activity" service. rather put appropriate flags on intent bring existing activity front if exists (e.g., flag_reorder_to_front ), rather create new one.

i'm leader of small team, , want advice of how divide tasks on developers of n-tier business software. scenario a: each developer has specific objects build @ layers (db, dal,bl, gui...) scenario b: each developer has domain of layers work on @ object !! scenario c: each developer work on specific schedule !! any advice help! thanks you should take account knowledge skills , experience of each of team members , divide work accordingly. if design correctly layered , decomposed there should no problem regards waiting on else since can stub out missing class(es) , continue on work. if time permits, may want assign portions of work members not familiar areas of system (either business domain or programming related) can learn areas , in time not become rounded programmers business benefit having more 1 team member being familiar various areas of system having deep understanding on business domain. it's win-win (with investment of time).

is below code reliable used determine whether device can support phone calls or not? concern if apple changes iphone string else let's decide have "iphone 3g", "iphone 4" etc. [[uidevice currentdevice].model isequaltostring:@"iphone"] the iphone supports tel:// uri scheme. use: [[uiapplication sharedapplication] canopenurl:[nsurl urlwithstring:@"tel://"]]; canopenurl: explicitly checks whether there's application capable of opening url scheme, not url correct. doesn't matter no phone number specified. method returns bool, check yes or no. that should literally answer whether there's application present capable of making telephone call. should okay against future changes in device segmentation.

while developing applications, go stored procedures contain crud logic, improve performance , maintainability. after experimenting linq sql, wondering whether, using compiled linq-to-sql queries on stored procedures improve performance? based on comments both devslick , a1ex07, seems have fundamental misunderstanding of linq is. in order linq queries allow chaining, like var activepeople = peoplelist.where(o => o.active).orderby(o => o.ordering).select(o => o.name); the execution of linq query must delayed until enumerated: foreach(var person in activepeople) { //if linq-to-sql, query peoplelist has waited until request database } this means query .where(o => o.active).orderby(o => o.ordering).select(o => o.name) not interpreted computer until point well. if run same query 100 times, means computer has reinterpret query 100 times. linq-to-sql, means translating query sql 100 times before sql sent database each time, if sql same every time

does have solution getting , setting variables in window.location.hash ? take url looks this: domain.com/#q=1&s=2 what i'd unstressful way - javascript or jquery - check values of q , s when page loads, , change them following events on page. i have found some code getting hash variables , nothing sensible setting them. am missing obvious, or need roll own solution (and release it!)? thanks. jquery bbq can this. see also: get url parameter jquery get querystring values jquery edit @gonchuki points out, jquery.query can this.

i have list of objects ordernum fields. the ordernum fields have match list order (but are not required continuous ). easy solution. reset every ordernum when list order changes: for (int = 0; < list.length; i++) { list[i].ordernum = i; } but ordernum stored in sql, the smaller amount of ordernum reset, better . when ordernum have reset, changes can big. there 32 bits use. ordered list retrieved by: select * orderable_items order order_num; the actual programming language c#. assuming numbers sparsely spaced, can following: compute target index in every element in original list compute longest increasing subsequence (o(nlogn)) on indices leave ordernum unchanged on elements in computed subsequence change ordernums on rest of elements fall appropriate gaps this assumes there's enough space between original ordernums. after several such reorderings might need readjust numbers case.

so rather not create profile file here: c:\users\fmerrow\documents\windowspowershell\microsoft.powershell_profile.ps1 i mean don't me wrong, isn't end of world , can live it. however, keep root "my documents" reasonably lean , rather not create directory there every time start using new application. i've nosed around looking setting might hidden, far no luck. doesn't seem in registry or of $pshome files. do have learn live this? . . . or there way change value of $profile "stick" on system time? is, change "default value" of $profile ? the best i've thought of far, ignore $profile , instead put code in $profile.allusersallhosts source/execute file want put instead of default $profile location. comments and/or other suggestions welcomed. frank i think solution source "new" profile in existing profile you're going get.

i'm working on project uses actionscript 3.0 flex sdks. project built using eclipse ide. wonder if flex sdks used support actionscript 3.0 in eclipse? what relationship between actionscript 3.0 , flash? its question, , 1 of many people tend confused with. - flash the singing, dancing graphics , vector stuff you'll aware of - deemed visual stuff. when open adobe flash, interface build animated stuff turned binary magic - actionscript 3 this began life small variable assistance flash graphicy stuff. has evolved (as you're aware) full blown language based upon ecma standard. why similar languages java , js - flex may become confusing here. flex has many forms. its xml style language of allows build 'flash' stuff via markup language, instead of drawing yourself. this begins become stable component set based on mxml (macromedia xml) syntax. flex wraps pretty entire as3 language mxml syntax , becomes framework its become norm have flex

our app needs grab files bluetooth inbox after pushed external hardware device. there way programmatically find bluetooth folder location? on galaxy it's /mnt/sdcard/bluetooth , , on desire seems /mnt/sdcard/downloads/bluetooth . thanks! as far can tell, there's no simple , easy way via apis (although there should be!) two solutions work (depending on usage context; first 1 seems better): on start-up, app checks if there's sharedpreference (e.g.) "bluetoothlocation". if doesn't find it, app searches either (a) fs or (b) fs rooted @ /mnt/ (probably (b) better) until finds file such that: the name.equals("bluetooth") , , isdirectory() . then saves path, , there go. alternatively (depending on context) could, the first time external device connects, sends file long, hard-coded filename (e.g. greoermmvemoper190erjvw0j9e2.txt ). app searches through fs until finds file shared, hard-coded name, , saves location. these both

i faced situation don't understand. have remote git repo running on webdav / apache. sure, logged on server , run "chown -r wwwrun:www *" , "git update-server-info" on relevant directory (as root, obviously). now, do: git clone http://myserver/myrepo then: $git remote show origin * remote origin fetch url: http://myserver/myrepo push url: http://myserver/myrepo head branch: master remote branches: master tracked trunk tracked trunk2.0 tracked local branch configured 'git pull': master merges remote master local ref configured 'git push': master pushes master (fast-forwardable) and change file, stage, commit , try push, results in: error: remote 'refs/heads/master' not ancestor of local 'refs/heads/master'. obviously, attempt pull pointless: $git pull up-to-date. the repository fine few days ago. how can work again? ok, resolved problem wrote in comment. used 1 of

possible duplicate: php 2-way encryption: need store passwords can retrieved i know best practice storing user passwords store irreversible hash of password. however, developing application need store user's login information web service -- i'll need periodically log them in , perform maintenance tasks. unfortunately, service doesn't offer authorization tokens (very apprehensively) have store passwords in way can access plain-text values. don't own or control service authenticating, , method 'borrow' users username , password , authenticate. i planning aes_encrypt passwords in db, means if somehow able access db won't able plaintext. code need have access key unencrypt them, if entire server compromised no protection , passwords revealed. aside above-described encryption, there best practices or steps can take safely possible? edit i know whatever do, passwords must accessible in plaintext , compromised server means passwords revea

i have network 1 server connected internet , clients not. want download , install microsoft products on server first , let client computers download installer later server. the questions where wpi save downloaded files? is possible run wpi , force install microsoft products downloaded files rather downloading again microsoft's server. note: assume there no license issue, hopely :-) it cached under %localappdata%\microsoft\web platform installer\installers if on vista or above, or in equivalent location on xp (there no %localappdata% environment variable in xp). if products downloaded, installed again cached location, unless updated, change hash , force web pi download them again. moreover, can copy cache folder 1 computer same location , web pi pick automatically , install products cached installers.

suppose have following revision graph, c current branch: c \ / b git rebase --onto b creates following: c / / b and git rebase --onto b a returns graph to: c \ / b however, new sha1 of c different old sha1 of c, before both rebasings. why case? the sha1 of commit depends on commit, including metadata. in particular, depends on commit timestamp. twice-rebased commit has new timestamp, has new sha1. (note there's "author date", when written, , "commiter date", when actual commit recorded. latter has changed. see yourself, use git log --pretty=fuller , or @ commit in gitk .)

i trying import customizations on server machine running dynamics crm 4. able upload customizations file on crm , shows me entities. however when try import these entities crm gives me sql server error. need details of error , therefore need enable tracing on crm server. how enable tracing on dynamics crm? have found quite many pages when googled term didn't quite looking for. there's diagnostic tool 4.0 enables tracing within crm you. enabling tracing causes crm emit ton of debug/error information , first step take when troubleshooting non-trivial issues. times error tell what's wrong. you can diag tool crmtools.zip link here . you'll want crmdiagtool4.zip file. extract contents of crmdiagtool4.zip onto crm server , run crmdiagtool4.exe. dropdown menu, choose "dynamics crm server". click first button enable tracing. enabling tracing huge performance hog, enable right before start import , disable right after error occurs. to read out

i'm learning grails, , working through the guide on testing. there's example provided covers writing test piece of code in fictional bookcontroller : def show = { [ book : book.get( params.id ) ] } the guide suggests following approach mocking out result of params.id : void testa() { bookcontroller.metaclass.getparams = {-> [id:10] } } as change on static definition of bookcontroller , persist between tests, or grails magic somehow automatically clean in teardown method? ie, if write subsequent test skipped setup of metaclass.getparams , ran after testa , params.id still return 10 ? if so, what's standard grails practice cleaning in test tear-down? doesn't seem covered in guide i'm reading. you're using ancient version of docs covering 1.0.x. testing support lot more solid now, see updated chapter 9 in http://grails.org/doc/latest/

in restful authentication , found current_user quite intricate that, when @current_user set false, means don't try find user again (usually db), while nil means that's ok, can again in db: line 8 of lib/authenticated_system.rb def current_user @current_user ||= (login_from_session || login_from_basic_auth || login_from_cookie) unless @current_user == false end the intricate thing is, if tries db login_from_session , etc, , can't find it, final value gets assigned @current_user nil , , method returns nil (which last evaluated value in method). unless there 2 other places in code elsewhere can set @current_user false, , trigger unless , causing whole statement return nil , while @current_user remains false , , method returns nil ... i speechless code rely on these intricate facts. false has special meaning, , nil has special meaning in code, not documented, not commented, , current_user can nil , while @c

is there t4 template generate typed dataset? i using ndbunit testing , have xsd automatically updated when change database schema. ideally xsd contain subset of tables in database. alternatively there command line tools, nant or msbuild tasks can this? mygeneration has strongly-typed dataset generator template , set of command-line opts enable invoke automatically part of build process. see http://www.mygenerationsoftware.com/portal/default.aspx more info, downloads, link latest version, , library of existing templates. also, because mygeneration supports persisting mygeneration 'project settings' , re-running them command-line, can save input choices make template (e.g., subset of tables want select db) , re-apply them when template re-run.
