i have variables incremented numbers within, such row0text, row1text, row2text, etc. i've figured out how dynamically create string versions of variable names, once have strings, how can use them actual variable names rather strings in code? example: var row3text = "this value need!" var firstpart = "row" var rownumber = 3 var secondpart = "text" var = (firstpart+string(rownumber)+secondpart) // below gives me concatenated string of 3 variables, i'm looking way have return value set @ top. println (together) once know how this, i'll able iterate through variables using loop; it's @ moment i'm unsure of how use string variable name in code. thanks! short answer: there no way for reason . use arrays instead. long answer: looking way define unknown number of variables linked common format. looking define ordered set of elements of variable length. why not use array? arrays containers allow store ordered set...

i'm new flex , have encountered problem itemrenderer can't find solution to. i've asked coworker plenty of flex experience, , i've tried searching internet no luck. problem have datagrid in each column uses itemrenderer display information, , reason causes user unable select of datagrid rows. think must have itemrenderer, because when added dummy column without itemrenderer, able highlight , select row clicking on dummy column, others still did not work. i've tried comparing code code other datagrids itemrenderers work, haven't been able find differences cause problem mine giving me. know why happen? thank you! my datagrid (i tried include think should relevant keep things concise. if thinks more information needed, please let me know!): <mx:datagrid id="servicegridui" left="10" right="10" top="10" bottom="85" selectable="true" stylename="formdatagrid" varia...

i have simple raw data format of column lastusagetime custom (yyyy-mm-dd hh:mm:ss): and pivottable: . the lastusagetime column max function (i want display dates, not count them). problem excel doesn't understand custom datetime format of raw data lastusagetime reason. puts 1900-01-00 everywhere. however, if copy text of lastusagetime , paste notepad, copy/paste excel, works fine! however, raw data sourced external xml file, when click refresh, gets messed again. how can fix this? i think need convert raw data lastusagetime string date/time value (as excel coercion copy/paste). perhaps: =datevalue(e2)+timevalue(e2)

spontaneously when started working on project earlier today function working fine earlier failed. curious because last time working on it, working fine. all left revert earlier stage of project in know fact function working. i reverted several previous stages , function still not functioning. other people when cloned work found functioning fine. when try access it doesn't work. the lead have git not functioning earlier. think file corrupted , fixed resetting working repository , copying on work. everything seemed fine after fix.my function working when pushed github. other people when cloned work found functioning fine the first workaround check clone repo in new location, , see if corruption persists there.

i have android app uses kitkat-level webview display documents (primarily e-reader consumes html files). when user opens document within app (and webview newly instantiated document) want scroll last known cursor location within document, user can pick reading left off. retain , persist cursor location indepedently of webview allow such scrolling when first open document. problem: when document first opens, can see initial highlighting of last known location (cursor) in javascript document, in perhaps 50% of cases i've seen document somehow scrolls top , cursor location no longer shown. how , why scrolls top in these cases mystery me (i dont believe programatically make scroll top in way). notes: achieve scrolling within webview i'm using javascript function invoked webview fragment (via webview.loadurl) once webview has signalled has loaded , ready use. callback document view fragment webview: @targetapi(build.version_codes.kitkat) @suppresslint("clickablev...

i need cleaning information doesn't make sense me, use cases if possible. what understand: with fragments in android, understand if plan on replacing them need have container view, preferably framelayout, , add initial fragment container during activities oncreate method. there 1 thing continues not make sense me. what don't understand , need with: what rules there regarding where/how container view set up, if there any. android developers site makes container view needs it's own xml layout file, doesn't , have seen examples on here framelayouts nested inside of typical layout files, specific uses , need understand rules of setting container up. there no rules. need viewgroup -- position , size want. when add fragment it, behave if you'd created fragment 's view manually, , called yourviewgroup.addview(fragmentview) . framelayout typically used because makes container no real behavior (you give size , position , let fragment fill con...

i looking suggestions on best practice declaring urls. property files or enum? edit : use java programming language. use hardwired constants in java code when don't want users / deployers / testers / tests changing them. use properties file when want possibility. the point changing hard-wired constant in application's source code entails editing source code, rebuilding , redeploying. contrast, changing properties file may simple firing notepad. constants - when don't mind re-compiling application each time change value. sort of irony here. why change if has been called constant :) properties file - when want luxury of changing value , maybe restarting application pick change.

i ran following command: git push -u origin master the "push" big, many files, taking time upload. halfway through noticed forgot add couple of files. did "ctrl + c" in terminal (interrupting git), , after doing git add . , committed again, , pushed again. will git know first 1 didn't go through ? takes long time push (so can't test easily. have wait push finish take while). edit: hooray! nothing seems have gone terribly wrong. did push again, , works. :{ the upstream git repository oblivious attempted push, , no change occur upstream. unfortunately however, doesn't half-pushed files, doesn't store , expect continuation of push later on either. it's either push or don't push, there no try;)
