i'm trying implement custom class including comparable mixin. later class used diff. class looks like class element include comparable attr_reader :name def initialize(name) @name = name end def <=>(other) @name <=> other.name end end now test values 2 added entries compared a. a = array.new b = array.new a.push element.new('y1') a.push element.new('y2') a.push element.new('y4') a.push element.new('x1') a.push element.new('x2') a.push element.new('x4') b.push element.new('y1') b.push element.new('y2') b.push element.new('y3') b.push element.new('y4') b.push element.new('x1') b.push element.new('x2') b.push element.new('x3') b.push element.new('x4') and run diff between both arrays puts diff::lcs.diff(a, b).inspect i expect 2 added objects finds 8 changes... ideas why?

why won't compiler pick correct version of overloaded method if has inferred types of input parameters. in example why can't pick correct math.max use when type has correctly inferred on elements being compared: let listmax = list.map2 (fun l r -> math.max(l,r)) [2;4] [5;3] //compile error let listmax2 = list.map2 (fun (l:int) r -> math.max(l,r)) [2;4] [5;3] //no compile error of course can use max function in case, there plenty of other methods don't have native equivalent. as @gos correctly points out, using pipeline operator helps in case. reason type inference works left right - so, if use pipeline operator, knows 1 of inputs list of integers and, based on that, picks right overload of math.max . the compiler needs know type when overload resolution or when want invoke member on object (e.g. if wanted l.foo() inside map function) - because in case, needs know type is. f# defines own versions of basic math functions work

this way harder looks like, think encountering kind of permission problems, not know do. testing purposes i'm using 777 permissions files. i want start executable file using php. i tried: <?php echo system('./fieldtheory'); echo shell_exec('./fieldtheory'); echo exec('./fieldtheory'); ?> but none of them execute file. tried executing simple shell script using system('./script.sh'); : #!/bin/sh echo "hello" /fieldtheory ./fieldtheory /opt/lampp/htdocs/fieldtheory ./opt/lampp/htdocs/fieldtheory i see "hello message" file not being executed. if execute file using terminal command: php testfile.php program being started without difficulties. edit : tried absolute paths no effect. double check php.ini , make sure exec functions not disabled: may have line this: disable_functions =exec,passthru,shell_exec,system,proc_open,popen,curl_exec,curl_multi_exec,parse_ini_file,show_source

this question has answer here: why arraylist implement ilist, icollection, ienumerable? 4 answers in .net framework 3.5 (c# 3.0) why system.hashtable implement both icollection , ienumerable when implements idictionary inherits these 2 interfaces? having these intefaces: interface ifoo1 {...} interface ifoo2: ifoo1{...} there no difference in terms of compilation between followings: class myclass: ifoo2{...} class myclass: ifoo2, ifoo1{...} the second declaration makes clearer developers interfaces myclass class implements. easier have @ documentation , see myclass implements ifoo1 interface, without digging ifoo2 interface.

this post have made on adobe forum... i'm newish flash , i'm doing presentation part of university assignment. my problem this. part of presentation have photo gallery uses thumbnail images buttons , ui loader load pop version of larger image webserver - per https://www.youtube.com/watch?v=peo_nt9hha0 the image created on photoshop. .jpg , has text within image describes underneath image about. text within photoshop set anti-aliasing 'smooth' , when test movie within flash, text underneath image looks fine - in photoshop. however, when publish , upload .swf file webserver , view image through browser, text looks awful - jaggy , broken if makes sense. any ideas why? i given reply of... if loading images dynamically have set smoothing property true after file(s) has been loaded. if don't have listener images finishing loading, need one, , event handler function assign smoothing property true each of them. can creating actio

in web i'm using servlet server. after have processed request, page made request. how do that? i have used "response.sendredirect(request.getparameter("url"));" i'm getting blank page instead of page made request. i appreciate every come. you use referer http header: public void doget(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception { string ref = request.getheader("referer"); response.sendredirect(ref); } but keep in mind, referer header optional , browser clients may not send it.

i have google spreadsheet two sheets . on first sheet , items listed in column a , , types in column b . on second sheet , reference first sheet's column a formula: =unique(sheet1!a:a) . then want color items in 2nd sheet based on item type ( 1st sheet's column b* ). try add conditional formatting using formula =sheet1!$b:$b="type1" , when try save rules , says formula invalid. what correct formula case? you cannot reference cells directly in conditional format formula. also, not think formula work. first, need vlookup function object's type. here's example of using function. difference corresponding data in first parameter preceded sheet name in case. see image: as can see, vlookup searchs item d in matrix a2:b4 , , returns corresponding value (the value in same row) in second column of matrix, column b . so if apply formula conditional formatting, have: =vlookup($d$2:$d;$a$2:$b$4;2)="dragon" the first paramet

i can't add scala-reflect dependency. project/build.sbt looks this: //the name of project, become name of war file when run package command. name := "test-sbt" version := "1.0" //specify scala version using in project. scalaversion := "2.10.3" librarydependencies <++= (scalaversion)(sv => seq( "org.scala-lang" % "scala-reflect" % "2.10.3", "org.scala-lang" % "scala-compiler" % "2.10.3" ) ) and project/build.properties sbt.version=0.13.0 and here main class: object main1 extends app { import scala.reflect.runtime.universe val runtimemirror = universe.runtimemirror(getclass.getclassloader) //...... } it says object runtime not member of package reflect . of course, did "gen-idea", "clean" , other things. what's that? guessing here due question @laughedelic. the build.sbt should in root. assuming project writing in te

one of delphi xe2 programs, when running , idle, 'prevents windows shutdown'. not case of applications , need resolve it. on xp, windows silently fails close; on win7 dialog shows application preventing shutdown. unlike similar questions here, program single-threaded, not using tray, , have temporarily disconnected onclosequery , formclose events in main form , 1 subsidiary form had them. in normal use program closes cleanly , no trace of remains in process explorer. i have experimemtally added wm_queryendsession , wm_endsession handlers write log message windows event log. on test windows shutdown, former fires, wparam , lparam both zero. i grateful ideas on causing this, or how investigate further. reluctant try call halt on wm_queryendsession without knowing going on. in final state failing, program had formclosequery methods reconnected, in each 1 checking 'shuttingdown' global boolean, , allowing close if set. shuttingdown set true in wm_que

i started using cgal demos find intersection of 2 polyhedra. met problem when 2 polyhedra share vertices , edges. program extis "segmentation fault" call. assume problem refers shared vertices, since other case see no problem. polyhedra e.g. rhombic triacontahedra or truncated tiracontahedra (the latter concave). problem of demo program or cgal algorithm itself? input off files use: https://www.dropbox.com/s/nywdv80yzr0wpxp/henley_3d.off https://www.dropbox.com/s/slxzfwhchpuix2p/henley_shift_3d.off i'm using cgal ubuntu 10.04 under virtualmachine win7 x64 host. i grateful you. best, radek first problem, polyhedra inconsistently oriented (which explain checkerboard coloration when open them in demo. second problem have non triangular facets not problem nef if vertices of facets coplanar (which not case). to fix can use "orient polygon soup" plugin , "inside outside" plugin fix orientation. plugin "triangulated facets" b

i have function below called , passed array. pass field (or key) name reusable. when try pass $field in callback below error $field not defined. if use literal, works great. function array_map_recursive($array,$field) { $sum = 0; foreach ($array $key => $value) { foreach ($value $key2 => $value2) { $sum += array_sum(array_map(function($item){return $item[$field];},$value[$key2])); } } return $sum; } called: number_format(array_map_recursive($dept_catg_grp_descs,"total_ty_yest_sales")) function ($item) use ($field) {return $item[$field];} this "imports" $field variable function.

this 1 might tough 1 explain. i've got program fills in pre-built crystal report (cr 2011) based on oracle database. i've applied logon information tables in report (and tables in 5 sub reports) through msdn tutorial based code. if not add code report once it's refreshed (such saving it, or sending printer) run through code without issue. however, if add code makes program useful, breaks below exception. here relevant code: try { (intcount = 1; intcount < rname.count(); intcount++) { logfile.logmessage(path, sreportpath); logfile.logmessage(path, sreportpath + rname.elementat(intcount)); //this line loading "c:\...\policy reinstatement.rpt" valid cr.load(sreportpath + rname.elementat(intcount)); crconnectioninfo.servername = sdatasource; crconnectioninfo.databasename = ""; crconnectioninfo.userid = suserid; crconnectioninfo

i have cell 017 , value , color of cell changing due formula , conditional formatting. cell o16 changes due formula formula , values different cell 017 . what want cell o16 contains same color of cell o17 automatically once value of cell 017 has changed. there should solution in vba. hope help. edit: user simoco has came solution excel 2010 , later: private sub worksheet_calculate() range("o16").interior.color = range("o17").displayformat.interior.color end sub unfortunately use excel 2007, there , equivalent code in 2007?. works excel 2010 , later if cell o17 can changed only through formula , use following code (this code should used in sheet module): private sub worksheet_calculate() range("o16").interior.color = range("o17").displayformat.interior.color end sub otherwise, add worksheet_change event same code.
