can reorder sqlite table columns via query? i prefer query method, if not possible there other way? yes, control order of columns order name them in query. both these queries return same rows, columns in different order. select first_column_name, second_column_name mytable; select second_column_name, first_column_name mytable; if want appear columns in base table have been permanently changed, can use view. create view mytable_reordered select second_column_name, first_column_name mytable; if wanted make change transparent application programs, you'd first rename table, create view, giving old name of table. finally, you'd jump through whatever hoops dbms requires in order make view updatable. in sqlite, think means writing code implement instead of triggers .

consider following scenario: a fifo named test created. in 1 terminal window (a) run cat <test , in (b) cat >test . possible write in window b , output in window a. possible terminate process , relaunch , still able use setup suspected. if terminate process in window b, b (as far know) send eof through fifo process , terminate well. in fact, if run process not terminate on eof, you'll still not able use fifo redirected process. think because fifo considered closed. is there anyway work around problem? the reason why ran problem because i'd send commands minecraft server running in screen session. example: echo "command" >fifo_to_server . problably possible using screen i'm not comfortable screen think solution using pipes simpler , cleaner one. a reading file. when reaches end of file, stops reading. normal behavior, if file happens fifo. have 4 approaches. change code of reader make keep reading after end of file. that's say

possible duplicate: php: remote file size without downloading file i want find size of file php when user enters link of file uploaded on different site. how? i assume want size of remote file. following php code should trick: <?php // url file (link) $file = 'http://example.com/file.zip'; $ch = curl_init($file); curl_setopt($ch, curlopt_nobody, true); curl_setopt($ch, curlopt_returntransfer, true); curl_setopt($ch, curlopt_header, true); curl_setopt($ch, curlopt_followlocation, true); $data = curl_exec($ch); curl_close($ch); if (preg_match('/content-length: (\d+)/', $data, $matches)) { // contains file size in bytes $contentlength = (int)$matches[1]; } ?> you first need obtain url file which, in relation mediafire , other file sharing websites, need code obtain after satisfying free user waiting period.

i'm php , actionscript developer, , in of functions use return end it. example: private function lolsome(a:string):void { if(a == "abs"){return void;} // function's code } i place function's code else , prefer way because in opinion, more legible. want know if considered bad practice or that. thanks! i consider bad practice if have returns inside long complicated functions because can harder else understand algorithm when looking @ it. however, bad practice have big long functions in first place (they should split multiple smaller functions). overall, consider validating parameters , state @ beginning of function , returning practice, not ok. but still careful not litter function several different returns within main logic.

from mentor: prefer native methods (implemented directly on collection) on extension methods of ienumerable, because: the linq-to-objects extension methods implemented on ienumerable, meaning in worst-case scenario (when item search not exist in collection) have enumerate thru elements. if have contains or exists method implemented directly on collection, make use of internal knowledge , maybe hash table or other quick operation. i confused, because think microsoft should have implemented hash table ienumerable contains/exists already. quick benchmark list , ienumerable show no differences: static void main(string[] args) { console.write("input number of elements: "); int count = convert.toint32(console.readline()); console.write("input number of loops: "); int loop = convert.toint32(console.readline()); random r = new random(); stopwatch sw = new stopwatch(); (int = 0; < loop; i++) { v

i have application written in c++ uses opencv 2.0, curl , opensurf library. first php script (cron.php) calls proc_open , calls c++ application (called icomparer). when finishes processing n images returns groups saying images same, after script uses: shell_exec('php cron.php > /dev/null 2>&1 &'); die; and starts again. well, after 800 or 900 iterates icomparer starts breaking. system don't lets me create more files, in icomparer , in php script. proc_open(): unable create pipe many open files (2) shell_exec(): unable execute 'php cron.php > /dev/null 2>&1 &' and curl fails too: couldn't resolve host name (6) everything crashes. think i'm doing wrong, example, dunno if starting php process php process release resources. in "icomparer" i'm closing opened files. maybe not releasing mutex mutex_destroy... in each iterator c++ application closed, think stuff released right? what have watch for? have

i have problem internet explorer , cache (i think). easy explained, i'm trying edit user in sql database using linq-to-sql, works perfectly. after user edited, sends me page i've made list of users, , can click on user want edit. the problem is, if click on same user edited, changes haven't been done, in database, have been changed, think there might problem ie cache or something. anyone knows if there way in visual studio clear ie cache specific page? know can press ctrl+f5, want update without having press ctrl+f5. btw, website programmed in c# , .net 4.0. you need refresh data context . l2s doesn't 'cache', such, needs prompting refresh data database, depending on how you've done data update.

i have c++ function like int f( const std::string &s, double d ); now i'd create variable holds pointer f . variable should have correct type ( int (*)( const std::string &, double ) - don't want write out type explicitely. i'd deduce f don't repeat type signature. eventually, i'd able write along lines of: typeof<f>::result x = f; to achieve this, tried this: // never implemented, used deduce return type can typedef'ed template <typename t> t deducetype( t fn ); template <typename t> struct typeof { typedef t result; }; // ... typeof<deducetype(f)>::result x = f; my hope maybe return type of function ( deducetype , in case) used template argument alas - seems can't that. does know how this? i'm looking c++03 solution. c++0x added decltype want (if understood correctly). another option might boost::typeof intended provide same functionality until decltype supported in compilers.

i'm creating asp.net site pages need have div floated left site menu in , other pages don't have menu div , instead content takes entire page width. i'm planning use master pages - wondering how best achieve - few immediate thoughts spring mind: create 2 master pages, 1 menu , 1 without. when creating content pages choose master inherit from. straightforward, may require more rework if site design changes create single master page content placeholder menu. on each page include menu div if needed (seems more messy approach) nested master pages? it seems may common problem, interested in how addressed. note questioning need having pages without menu - simpler if pages had same structure. nested master pages standard answer , should work well. an alternative approach occurs me put menu in panel control on master page , expose property lets toggle visibility of panel. have not tried yet, not sure how practical is, might fun concept play with. if

i've read quite few q&a's on filtering user input here, of time answer depends on you're doing. here's i'm doing: data submitted via form used in mysql query: function clean($field, $link) { return mysql_real_escape_string($field, $link); } data submitted via form displayed on html/php page or in email: function output_html($value) { return stripslashes(htmlspecialchars($value)); } data displayed database: function output_db($value) { return stripslashes($value); } is sufficient needs? there i'm not considering? thanks! use mysql_real_escape_string() when inserting strings sql queries, no matter input comes from. use htmlspecialchars() or htmlentities() when inserting strings html code, no matter input comes from. use urlencode() when inserting values query string of url, no matter values come from. if data comes user, should these things because there chance user trying bad things. security aside--what if
