c++ - Difference Between GUI debugger and terminal debuggers -

what advantages gui debugger in eclipse , advantages using command line debugger such gdb? industry use command line debuggers? , if so, situations people use command line debuggers? i use gdb, advantages can think of off top of head: being command line, debugging binaries on remote systems easy opening ssh connection. great scripting support, , ability run many commands per breakpoint (see continue keyword) much shorter start-up time , faster development cycle. copy&pastable commands , definable functions let repeat common commands easier gdb speaks well-defined protocol, can debug code running on lots of obscure hardware , kernels. typing short commands shorter , more efficient in long run working around gui (in opinion). however, if you're next system or runtime you've never used before, using visual debugger can easier started get-go. also, having debugger tightly integrated ide (if use one) can big boost in productivity. visual debugger , com...

Image
i sending value of variable http url cfm page, not sure how value on other page. in php use $_get['variable'] ; not sure equivalent of in coldfusion. coldfusion has option of accessing these variables you're doing in php: php: $foo = $_get['variablename']; $bar = $_post['variablename']; cfscript: foo = url['variablename']; bar = form['variablename']; cfml: <cfset foo = url['variablename']> <cfset bar = form['variablename']> edit: discussion of form scope case insensitivity, , workaround coldfusion (helpfully?) convert form fieldnames uppercase in form scope. in cases fieldname repeated, multiple values merged single comma-separated value. when don't have control on form itself, can lead frustration. given form: <form name="main" action="handler.cfm" method="post"> <input type="text" name="confusion" value="abc...

jQuery & PHP: Upload an image and refresh gallery page with new thumbnail -

i have page contains thumbnails photo gallery. on page link upload more images. when click link modal opens contains upload form (jquery colorbox in iframe) allow upload 1 image (plus name, caption, etc) @ time using php. when form submitted image uploads , page refreshes in modal allow more uploads. since modal sitting on top of existing thumbnails i'd user see new thumbnail added page after it's uploaded. possible? how this? i'm assuming modal in iframe . if that's case, when upload submitted, , modal form reloads allow upload, send uploaded file info (thumbnail url) parent frame. example: parent.uploadcallback('http://my.domain.com/newly-uploaded-thumbnail.jpg'); then have uploadcallback function in main frame creates img object , appends list of thumbnails.

How to use Java's DecimalFormat for "smart" currency formatting? -

i'd use java's decimalformat format doubles so: #1 - 100 -> $100 #2 - 100.5 -> $100.50 #3 - 100.41 -> $100.41 the best can come far is: new decimalformat("'$'0.##"); but doesn't work case #2, , instead outputs "$100.5" edit: a lot of these answers considering cases #2 , #3 , not realizing solution cause #1 format 100 "$100.00" instead of "$100". does have use decimalformat ? if not, looks following should work: string currencystring = numberformat.getcurrencyinstance().format(currencynumber); //handle weird exception of formatting whole dollar amounts no decimal currencystring = currencystring.replaceall("\\.00", "");

php - CakePHP: Translating database 'inheritance' into app models/controllers -

i designing database system containing number of different user types. schema this: ## users id int name varchar(60) email varchar(60) ## doctors id int user_id int specialism varchar(60) qualification_id int essentially, doctors table child of users table. now, when i'm creating models , controllers , models in cake, thought logical create user model , subclass doctor model . doesn't seem work when testing $scaffold (the 'has one' , 'belongs to' relationships work relatively well, way not subclassing users classes). what approach suggest database designed in way? cakephp not designed this. cakephp uses activerecord pattern. pattern works great when models match database tables. breaks down when want set models in way trying now. setup, you'd need data mapper pattern (as implemented e.g. zend_db). in case, set user , docter 2 separate models hasone/belongsto relation. far easier go cake-ish flow fight it.
