is possible use guids identifier in resource files? in program user able chose between possible types when creates item. item chosen saved via guid. but hyphens in guids seem problem resource files. there better solution use replace in order remove every hyphen guid before looking typename in current language? how turning guids strings? you can use guid.tostring("n") produce string guid without hyphens. you may have put non-digit @ start - if do, it's easiest string.format(): string guidstr = string.format("x{0:n}", guid.newguid()); // prefix "x"

the following javascript/jquery snippet applies css matchicng elements in dom. $('.centeredbyjquery').each(function(){ $(this).css({'margin-left': -parseint($(this).css('width'))/2, 'left':'50%', 'margin-top': -parseint($(this).css('height'))/2, 'top':'50%'}); }) how apply method future matching elements ? you can't.. way using interval: setinterval(function(){ $('.centeredbyjquery').each(function(){ $(this).css({'margin-left': -parseint($(this).css('width'))/2, 'left':'50%', 'margin-top': -parseint($(this).css('height'))/2, 'top':'50%'}); }) },1000); but terrible idea.. if know when new element inserted, can call function center element.

how can resolve maven cyclic dependency. suppose parent project , b , c child projects. if b dependent on c , c dependent on b, there way resolve cyclic dependency other having different project. thanks in advance, have searched in forums, not exact solution. please let me know if there possibility. maven not allow cyclic dependencies between projects, because otherwise not clear project build first. need rid of cycle. 1 solution 1 mentioned, create project. 1 move classes b c or vice versa when helps. or correct merge project b , c 1 project if there no need have 2 of them. but without knowing , analyzing why projects depend on each other it's kinda difficult suggest best solution. so suggest can use tools jdepend or intelij analyse tool find problematic classes , based on them find better design software. most of time, create interface module , and implementation module, gets rid of cycles.

i want save result aggregation csv file. using mongo cmd line tool can results want: db.compras.aggregate({ $group : { _id : "$data.proponente", total : { $sum : "$price" } }} how translate mongoexport command saves results csv? you can't run aggregate() queries through mongoexport . mongoexport tool intended more basic data export query filter rather full aggregation , data processing. write short script using favourite language driver mongodb, though.
