i have uitableview cells containing variable-height uilabels. able calculate minimum height label needs using sizewithfont:constrainedtosize:linebreakmode: , works fine when table view first loaded. when rotate table view cells become wider (meaning there fewer lines required display content). there way can have height of cells redetermined uitableview during orientation change animation or before or after? thank you. your uitableviewcontroller can implement tableview:heightforrowatindexpath: method specify row height particular row, , can @ current orientation ( [[uidevice currentdevice] orientation] ) decide height return. to make sure tableview:heightforrowatindexpath: gets called again when orientation changes, you'll need detect orientation change described in this question , , call [tableview reloaddata] .

the firebugx.js file (shown below) checks both !window.console , !console.firebug, correctly detects if firebug installed. however, check not accommodate native console object in ie developer tools -- overwrites ie console object. for example, if include firebugx.js code, following exception not appear in ie console (it swallowed): function foo() { try { throw "exception!!!"; } catch (e) { console.error(e); } } question: best approach accommodating ie developer debugger? maybe obvious answer comment out firebugx.js check when debugging in ie. there other approaches? reference: firebugx.js if (!window.console || !console.firebug) { var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml", "group", "groupend", "time", "timeend", "count", "trace", "profi...

it seems both (mapcar 'car '((foo bar) (foo1 bar1))) and (mapcar #'car '((foo bar) (foo1 bar1))) work same. and know ' means (quote symbol) , #' means (function function-name). but what's underlying difference? why these 2 both work in previous mapcar ? 'foo evaluates symbol foo. #'foo evaluates function bound name foo. in lisp symbol can called function when symbol foo has function binding. here car symbol has function binding. but not work: (flet ((foo (a) (+ 42))) (mapcar 'foo '(1 2 3 4 5))) that's because foo symbol not access local lexical function , lisp system complain when foo not function defined elsewhere. we need write: (flet ((foo (a) (+ 42))) (mapcar #'foo '(1 2 3 4 5))) here (function foo) or shorthand notation #'foo refers lexical local function foo. note in (funcall #'foo ...) vs. (funcall 'foo ...) the later might 1 more indirection, since ...

i have mobile app uses socket connection communicate server. however, seems users complaining port blocked isp, or wireless network. is there range of ports are well-known enough not blocked not used mobile devices use? or there better way address issue? asking isp/wireless network admin unblock port not feasible thing me do. edit: i'm looking @ canadian, us, , european mobile operators in particular. the best , port use 80 standard http traffic. you try... 443 ssl http traffic 8080 backup http traffic port used proxy servers or links. but if remotely worried networks blocking traffic standard http , port 80 ways go. networks allow port 80 if allow thing. btw times way ask isps/networks open port server isn't ideal if block port 80 going have ask them.

so firefox supports gradient backgrounds. supports multiple background images.. why not work?? background:-moz-linear-gradient(top, #5989bd,#336296), url(active-arrow.png) right center no-repeat; also tried: background-color:-moz-linear-gradient(top, #5989bd,#336296); background:url(active-arrow.png) right center no-repeat; can done?? you must include background image before linear gradient. e.g: background: url("http://127.0.0.1/css/bg.png") no-repeat, -moz-linear-gradient(top left, rgb(0,255,0), rgb(255,0,0));

could me finding file name string. have 1 string of content "c:\xxxx\xxxx\xxxx\abc.pdf". want file name ie. abc.pdf. how using string functions? use path.getfilename : string full = @"c:\xxxx\xxxx\xxxx\abc.pdf"; string file = path.getfilename(full); console.writeline(file); // abc.pdf note assumes last part of name file - doesn't check. if gave "c:\windows\system32" claim filename of system32, though that's directory. (passing in "c:\windows\system32\" return empty string, however.) can use file.exists check file exists and file rather directory if help. this method doesn't check other elements in directory hierarchy exist - pass in "c:\foo\bar\baz.txt" , return baz.txt if foo , bar don't exist.
