Funaction

this seems basic question know i've not been able find answer. let's assume basic function: function basicfunction ( $var1, $var2 = 1, $var3 = 2, $var4 = 5 ) { // stuff // return } now let's assume want call function following variables: $var1 = 0 $var2 = 1 $var3 = 2 $var4 = 3 i can this: $someresult = basicfunction( 0, 1, 2, 3 ); $var2 , $var3 set though, how call function without having repeat value $var2 , $var3 ? php not support overloading. therefore, cannot skip them in way if don't move them right of list of arguments. a common solution set default value of different type expected (i.e. null). actual default value set within function. approach not clean , takes lines of code, if situation requires it, can go this: function basicfunction($var1, $var2 = null, $var3 = null, $var4 = null) { if ($var2 === null) { $var2 = 1; } // ...

i'm trying learn haskell i'm having problem in monad usage. i imported module data.maybe . but don't know how use >>= operator. given (>>=) :: monad m => m -> (a -> m b) -> m b cannot understand how define function (a -> m b) . can provide pedagogical example? for maybe monad bind function ( >>= ) looks that: (>>=) :: maybe -> (a -> maybe b) -> maybe b so, let's define maybe a value: > let = 1 :: maybe integer and :: -> maybe b function: > let f = \x -> (x+1) f :: integer -> maybe integer now can use bind infix operator: > >>= f 2 :: maybe integer another example of a -> maybe b function be: let h :: integer -> maybe string; h = return . show . (+1) h :: integer -> maybe string so h increment integer number, convert string , make maybe value return function. > >>= h "2"

i trying make textblock turns editable delayed double click. similar functionality in windows explorer when delayed double click edit file , folder names. possible? what seeing in windows explorer single-click on selected/focused item initiating rename operation. first click you're seeing selects/focuses item , second click initiates rename operation. can verify using keyboard select different item , single-clicking on newly selected item. it appears there short duration (e.g. half second) between click on selected/focused item , ui going rename mode. so... if item clicked on has focus, you'll need starting timer. if item still has focus when timer expires, enter renaming mode. from there matter of applying correct template whichever trigger/flag logic care implement. edit : search on wpf in-place editing , should find code examples. note : f2 key tends initiate rename operations on selected items if want wire in well.

i have rails app gives me error once in while: errno::enomem error coming function: def create_folder new_dir = self.id.to_s working_dir = '/home/user/files/' # line causing error: %x[cd #{working_dir} && mkdir #{new_dir}] working_dir = working_dir + new_dir + '/' self.working_dir = working_dir self.save! this error happening controller, upon creation of model calls above mentioned function... would grateful if points out how deal it.. i cannot see pattern in why happens or when.. just record. error went away moment started using ruby's dir. so %x[mkdir nnn] # bad dir.mkdir("bbb") # good.

what easiest format read texture opengl? there tutorials -good tutorials, loading image formats jpg, png, or raw array can used texture mapping (preferably without use of library libpng)? opengl not knows nothing common image formats (other natively supported s3tc/dxt compressed , alikes, different story). need expand source images rgba arrays. number of formats , combinations supported. need choose 1 suits you, e.g. gl_alpha4 masks, gl_rgb5_a1 1bit transparency, gl_bgra/gl_rgba fullcolor, etc. for me easiest (not fastest) way pngs, lossless compression , full alpha support. read png , write rgba values array hand on opengl texture creation. if don't need alpha may accept jpg or bmp. pipeline common source -> expanded rgba array -> opengl texture.

i'm developing application in java/android allows user compress , decompress files. @ first, started study file size such as: 1byte = 8bits 1kb = 1024byte 1mb = 1024kb 1gb = 1024mb 1tb = 1024gb 1pb = 1024tb 1eb = 1024pb 1zb = 1024eb 1yb = 1024zb after studied this, studied , read articles on net , found out there 2 types of file compression (correct me if i'm wrong): lossless , lossy. lossless compression means file compressed smaller bit without losing single file while lossy compression means important files being removed while compressing file. i read compression(run-length coding method) this: aaabbccdffffeeeeh to this: 3a2b2cd4f4eh which gives me idea on how compressing/decompressing works on file. i searched net there api compressing file on java(also applicable on android) is java.util.zip i tried codes on compressing , decompressing file various helpful websites/forum/etc (including stackoverflow.com) gives me experience study. i read algorit...

so general question: if have file structure have index page in root folder along scripts folder, , in scripts folder there 2 scripts 1 js referenced in index page, , other php referenced js script: root-folder: --> index.html --> scripts/ -----> myscript.js -----> myscript.php how should access php script js script using relative url? would be: ./myscript.php or ./scripts/myscript.php in other words relative url index file or js file. thanks! since javascript operating in scope of page, not physical location, url php include /scripts/ in path name.

i have problem google analytic . here code : <script> function trackregister() { if(dataform.validator.validate()) { _gaq.push(["_setcustomvar",4,"type","besogende-med-konto",1]); _gaq.push(['_trackevent', 'activatevisitorprofiletracking', 'activatevisitorprofiletracking']); _gaq.push(['_trackevent', 'konto-oprettet', 'engage', 'personlig-konto-oprettet']); } } i call trackregister function when click submit button page redirect result page ,but receive activatevisitorprofiletracking event on google analytic report. don't know why .anyone can me? thank :d based on description of how calling it, sounds maybe page being redirected before 2nd _trackevent call has chance execute. try wrapping redirect in settimeout , or wrapping ga code code detect status of ga calls , redirect when returns complete

in straight mysql script i'd transactions this: start transaction; select @a:=sum(salary) table1 type=1; update table2 set summary=@a type=1; commit; i'm little confused how transactions work in pdo. looks there begintransaction() , commit() methods - i'm not sure these convenience wrappers around staright sql? or doing more job behind doors? in other words - these examples below same? example 1: $dbh->exec( 'start transaction' ); //...do db work here... $dbh->exec( "commit" ); example 2: $dbh->begintransaction(); //...do db work here... $dbh->commit(); functionality wise both same, begintransaction() , commit() pdo functions ensures compatibility database , there might database may give error @ start transaction pdo methods work.

having headaches in rcpp handling strings, have looked @ "how test rcpp::charactervector elements equality" situation bit more complex that. to illustrate, suppose have 200-row data frame of names , marks, generated randomly: df = data.frame(name = paste("person", sample(letters[1:10],200,rep=true),sep=""), mark = pmax(pmin(round(rnorm(200,60,15)),100),0), stringsasfactors=false) i found following inline code (using rcpp) correctly works out sum of marks rows person named first person given in data frame (i.e. df$name[1] in r, or equivalently name[0] in rcpp code): library(inline) fastfunc_good1 <- cxxfunction( signature(dfin = "data.frame"), plugin = "rcpp", body = ' rcpp::dataframe df(dfin); rcpp::charactervector name = df["name"]; rcpp::integervector mark = df["mark"]; rcpp::charactervecto...
