is possible use async image loader project http://open-pim.com/tmp/lazylist.zip gallery widget? tried: public view getview(int position, view convertview, viewgroup parent) { imageview imageview=new imageview(activity.getbasecontext()); imageloader.displayimage(urllist.get(position), activity, imageview); imageview.setscaletype(imageview.scaletype.fit_center); imageview.setlayoutparams(new gallery.layoutparams(150, 150)); return imageview; } but had no effect. you must tag image views appropriately asynchronous task can update them once images retrieved cache or network: imageloader.displayimage(urllist.get(position), activity, imageview); imageview.settag(urllist.get(position));

what better dynamically loading images- using ajax function or changing image's src attribute desired link? please supply snippet of code answer. thanks depends on definition of "better," since javascript doesn't deal binary streams, i'd recommend "changing image's src attribute" option. var mysource = '/path/to/image.jpg'; var img = new image(); img.src = mysource; // or $('#someimageid').attr('src', mysource);

i use: ... $('#form').submit(function(e) { ... <div id="list"> <jsp:include page="list.jsp" /> //form here </div> ... to handle form's submit , works. can handle form's submit. however moved form list.jsp think can't recognize inside of jsp file can't handle form's submit. want ability within list.jsp too. what should do? based on code provided, looks trying attach event form before it's rendered. wrap event binding in onready function. $(function(){ $("#form").submit(function() { ... }); }); if doing, make sure form rendered jsp include has id="form" .

basically, best way of doing this? i have enum has possible resolutions , want them displayed on drop down combobox. so far, found bind enum combobox like: combobox2.datasource = enum.getnames(typeof(resolution)); however, in method, have: public void testmethod(resolution res){} and can't think of way convert back. thinking of changing method use string, have case or if s in method convert enum. in addition, ideally want of names have spaces. have read [description("description spaces")] think gets applied on tostring. even if sort of loop , add each item box via tostring, still return string. i not sure how proceed other dump enum , go different approach. i wondering in similar situation, do? i use lookupedit instead, , tie enum value key , enum.getnames(typeof(resolutions)); displayed value on edit. when user selects item actual value instead of name.

i'm connecting government web services on rails application, using savon library. however, web services hosted on looks poorly configured machine, , openssl library refuses work them. since java , .net clients working fine, started alternatives. i've changed ruby runtime ruby enterprise edition jruby, not use openssl libraries (it 'forwards' ssl implementation java itself), , worked great. so i'm looking alternative writing ruby web service client using https not openssl. there pure-ruby implementation of tls/ssl? or other library can bind to? i've heard nss, looks it's deprecated. does machine have libcurl installed? following libraries use libcurl (which uses openssl internally) , it's possible libcurl 'well' configured guess. need libcurl header files compile , install these gems though... curb patron typhoeus i've never heard non-openssl ssl/tls implementation ruby.

is there quick way (without overhead of using gui or graphics module) visually render 2d , 3d lists. for example if have 2d array of zeros , ones, draw black , white grid according array. i looking module allows me these thing in simple ways. similar easiness of matplotlib allows drawing graphs. the command matshow in matplotlib displays matrix: import pylab p p.matshow(p.array([[0,1],[1,1]]),cmap="greys") ; p.show() this work 2d lists. 3d lists, i'm not sure understand how you're planning on visualising them.

i trying multiple number of 2 , 3 pls help. thanks for($i = 0; $i <30; $i++) if($i % 2) echo 'number '. $i . ' multiple of 2 <br/>'; elseif($i %3) echo 'number '. $i . 'is multiple of 3 <br/>'; else echo 'number '. $i . 'is multiple of other number <br/>'; try this: if($i % 2 === 0) ... elseif($i %3 === 0) ... basically if modulo 0 means number evenly divisible. however, problem logic number may divisible both 2 , 3 . can fix extracting these out separate if statements: if($i %2 === 0) { ... } if($i %3 === 0) { ... } but sort of breaks last else since cannot fall though anymore. solve setting variable false @ top of loop. if of if statements triggered, set variable true . finally, print "not divisible" message @ end of each iteration if variable still false .
