i have layout xml file linear layout. 1 of children again viewgroup relative layout. in java code want change width of child viewgroup requirements. tried this enter code here viewgroup childviewgroup = (linearlayout)findviewbyid(childviewgroup); layoutparams l = childviewgroup.getlayoutparams(); l.width = 360; childviewgroup .setlayoutparams(l); i couldn't because findviewbyid(childviewgroup) doesn't fetch viewgroups views. note : cant define whole new layout.xml minor requirement since huge layout file , might cause performance overhead. wanted change width of child view group in java activity code. thanks in advance help. viewgroup subclass of view findviewbyid should work fine. you're casting result linearlayout, childviewgroup linearlayout or relativelayout specified in question? – codelark oct 6 @ 23:21

what difference between xelement , xdocument , when use each? xdocument represents whole xml document. composed of number of elements. xelement represents xml element (with attributes, children etc). part of larger document. use xdocument when working whole xml document, xelement when working xml element. for example - xelement has hasattributes property indicating whether attributes exist on element, xdocument doesn't, such property meaningless in context of whole xml document.

in direct3d, can create type of vertex like. can have simple vertex positional information, or add colour info, texture info, etc etc. when creating input layout, define parts of vertex you've implemented: d3d10_input_element_desc layout[] = { { "position", 0, dxgi_format_r32g32b32_float, 0, 0, d3d10_input_per_vertex_data, 0 }, { "color", 0, dxgi_format_r32g32b32a32_float, 0, d3d10_append_aligned_element, d3d10_input_per_vertex_data, 0 }, }; my question is, should define vertex structure all of input types (position, colour, texture etc etc). or should create several vertex structures, each different types of input. the downsides using multiple classes have create , maintain several classes, , confusing knowing type of vertex use. downsides of having 1 vertex structure? you upload unused vertex data 3d accelerator, , eat bandwidth. shouldn't matter unless doing top notch video game (you'll have bottleneck somewhere else). ...

i have read book o'reilly states 70-80% of performance of site can optimized via front-end. may mean database queries may account less 20 or 30% of site's performance. however, have seen huge websites facebook , twitter dedicate time optimizing queries (via query caching, normalizations, etc). when database become critical site's performance can account more aforementioned percentage? oh, , performance mean in context of speed, loading speed in particular. when database become critical site's performance can account more aforementioned percentage? after have optimized front-end max, relative impact of back-end become larger. also, big sites face problem of scalability. might able serve single user fast, load grows, gets slower everyone. client-side part spread across users' machines, scales well. back-end shared everyone, , become bottleneck.

i have e-shop multiple product types. , have thought of following structure cart_item -- cart_product -- cart_download order_item extends cart_item -- order_product -- order_download the problem want have order_product extend order_item , cart_product. because needs method generic order_item ( price order not product ) methods cart_product ( shipping calculations ) i know php doesn't support multiple inheritance, wandering cleanest way emulate this. right have order_product extend cart_product duplicate code order_item in order_product order_download. either use interfaces , implement methods manually or via strategies . or use composition instead of inheritance, meaning let order_product have order_item , cart_product . on sidenote: consider making "shipping calculations" it's own service class can pass appropriate product instances to.

i have local apache server, , need pass requests php script (running on local server) through proxy. need set proxy apache/php. how configure apache server proxy outgoing connections ? well answer partly yes. php has socket opening functions, theoretically can defining own functions. php has introduced context parameter of functions external calls. example usage file_get_contents following: $url = 'http://www'; $proxy = 'tcp://xxx:8080'; $context = array( 'http' => array( 'proxy' => $proxy, 'request_fulluri' => true, ), ); $context = stream_context_create($context); $body = file_get_contents($url, false, $context); but cannot "something" make requests magically go through proxy. not entirely true well, have on layer. have possibility use vpn work great emulates network card. there utilities same socks proxies, heard hacks port through http proxies think rather unlikely...

we use svn(subversion) our source repository. on same box, build our project plus deploy onto appserver. team members(under 10, in number) login linux (ubuntu server) box , run build script. question : know directory typically used creating home directory subversion checkout , doing build. type of permissions should giving teammembers can come in dir, update source code(svn update) , run build script (ant). p.s : i'm interested in understand best-practices. thank you, sounds need continuous integration server. install hudson on server , use instead. hudson automatically check out changes subversion , build them when checked in. can make deploy app server after successful build. , can trigger builds manually if want, example release. you'll find easy started with.

in ipad application, have 768x30 px view place below status bar coordinates (0,0). status bar visible. when app launches status bar overlaps view, view appears under status bar. creating view in interface builder , appears correctly on there. the view appears in correct position automatically after screen rotates though. , if rotate landscape position still correct. right after launch, before rotations appears out of place. ideas? thanks edit : in app delegate's didfinishlaunchingwithoptions, add viewcontroller.view.frame = window.screen.applicationframe; this somehow magically tells view controller have correct frame both when app launched (in orientation) after rotating device. previously, had suggested: i able resolve issue adding window nib , adding view it, then. hopefully too.

i wrote script sync several servers @ once. 1 of problem cannot lftp preserve initial file modification time. basically, upload files while changed. do know how force lftp preserve file modification time when downloading or uploading? thanks help. korchkidu on following page http://www.bouthors.fr/wiki/doku.php?id=en:linux:synchro_lftp the authors state: when uploading, not possible set date/time on files uploaded, that's why –>ignore-time needed. so if use flag combination --only-newer , --ignore-time can achieve decent backup properties, in such way files differ in size replaced. of course doesn't if need rely on time-synchronization if perform regular backup of data, it'll job.

for experienced wpfers out there, how re-usable wpf, silverlight , silverlight oob applications , components? how overlap there? for example, write 1 application , deploy in 3 aforementioned ways? ideally, want write little code possible , have flexibility of deploying in range of scenarios, maybe enabling functionality depending on deployment. wpf family of technologies seems starting point casual observer.. really? the simplified version of answer is: 1. silverlight subset of wpf. 2. silverlight in browser apps , silverlight oob apps running on same framework. deployment difference. 3. oob apps can installed "trusted" apps, , have looser security restraints in browser apps. porting wpf app silverlight going difficult, wpf app use many features of .net framework not available in smaller subset of framework available silverlight apps. want avoid. porting silverlight app wpf easier. still challenge there features in silverlight not in wpf (though not ma...
