i'm trying find way add class td based on whether it's positive or negative, not within first <tr> , not within first <td> of <tr> . i can't find on either issue through searching. know how this? you mean if <td> contains positive or negative number? if that's you're trying do, use this: $(document).ready(function() { $("tr:not(:first)").find("td:not(:first)").each(function() { if ($(this).text() > 0) $(this).addclass("positive"); else if ($(this).text() < 0) $(this).addclass("negative"); }) }); i tested on following table , worked fine: <table> <tr> <td>3</td> <td>9</td> <td>-3</td> </tr> <tr> <td>8</td> <td>-4</td> <td>9</td> </tr> <tr> <td>-7</td> <td>12</td> <td>144</td> </tr> </table>

there siteminder rule placed in allow access "/public/*" pages unauthenticated users. in mvc folder structure there no physical folder (or area) called "public" , don’t want should able add public pages freely in area. now, unauthenticated users not have access public pages (actions). need workaround through siteminder public pages. there 2 things in mind need find solution. rewrite routes prepending "/public" them (conditionally may based on authorized attribute) siteminder. once url received "/public" should routed proper area/controller/action ignoring "/public" portion of it. i still couldn’t figure out way code above. if experts know how achieve above or have different thoughts please post. cheers, moosila finally question narrowed down "how can rewrite route adding "/public" after root , before area/controller/action?" i did poc achieve above of co-worker: using reflection obtain appropriate co...

i need override connection between boost::signals2::signal , boost::function . purpose i've created following template function: template<typename t> void bind(boost::signals2::signal<t> &signal, boost::function<t> function) { // override code ... } i want make use of bind simple can be. i've read in posts on similar issues, template parameter should deduced function arguments. in case when there's no explicit parameter it's not working. boost::signals2::signal<void ()> my_signal; bind<void ()>(my_signal, boost::bind(&a::func, this)); // works bind(my_signal, boost::bind(&a::func, this)); // error: no matching function call am missing something? can there workaround avoid explicit template parameter? the second argument type not std::function<t> , bind type, compiler unable deduce t second function parameter. need tell compiler "you ok not finding type t in second function parameter". can done making...

i'm developing tour application storing , displaying information different sights , sculptures, , i'm investigating different options store information. all of content generated before runtime , , nothing generated @ runtime. i'm looking convenient way write/generate it , such fetching information spreadsheet. therefore considering xml , csv , sqlite , core-data , or archiving . the content stored custom subclasses of nsobject , such tour class (nsobject subclass), instance variables such nsarray of sights (nsobject subclass) view, , *tourname (nsstring). i define content in - (id)initwithnibname:(nsstring *)nibnameornil bundle:(nsbundle *)nibbundleornil method of main view controller, i'm it's not efficient way. any suggestion welcome, advantages , disadvantages. also, core-data seemed best option, seemed me data generated programmatically @ runtime. or there way generate instances of entities in core-data before run-time ? thank you. you can generat...
