currently have list of integers. list contains index values point "active" objects in another, larger list. if smaller list of "active" values becomes large, triggers loop iterates through small list , removes values have become inactive. currently, removes them ignoring inactive values , adding them second list (and when second list gets full again same process repeated, placing them first list , on). after trigger occurs, list sorted using quicksort implementation. fine , dandy. -------question--------- however, see potential gain of speed. imagining combining removal of inactive values while sorting taking place. unfortunately, cannot find way implement quicksort in way. because quicksort works pivots, means if values removed list, pivot try access slot in list not exist, etc etc.. (unless i'm thinking wrong). so, ideas on how combine 2 operations? can't seem find sorting algorithms fast quicksort handle this, or perhaps i'm not seeing ho

i using datatables.net library don't print output (instead, format own printable table looks different style of data-table, keep data-table style display non-print purposes). one option library has export data table javascript object, can access data datable , whatever want. so options solution be: 1) create separate html page table & css prepared , printing via window.open() query string parameters , window.print() on-load of that. 2) same #1 big hidden input field , form post/request. 3) stay on same page, dynamically draw table, hide don't want print, window.print(), remove dom newly added table , re-show non-printable stuff. what guys think, 1 of solution, or there better option? note: data-set not massive, as 30 rows , 10 columns. well nobody seems have input on yet ive decided move forward using form post method & hidden fields. example of can seen here: posting javascript , creating hidden field on fly that link points answer on else

"start of line" metacharacter (^) matches @ start of string, while "end of line" metacharacter ($) matches @ end of string, or before terminating newline (unless d modifier set). same perl. when modifier set, "start of line" , "end of line" constructs match following or before newline in subject string, respectively, @ start , end. equivalent perl's /m modifier. if there no "\n" characters in subject string, or no occurrences of ^ or $ in pattern, setting modifier has no effect.

i prototyping payment via paypal , stuck on how specify url browser should redirect/link after payment. <script src="paypal-button.min.js?merchant=stan-facilitator@merkwelt.com" data-button="buynow" data-name="new bot" data-quantity="1" data-amount="0.99" data-shipping="0" data-tax="0" data-callback="http://www.merkwelt.com/people/stan/paypal/success.html" data-env="sandbox" ></script> i aware difference between callback (for reporting) , return url (what happens in browser). browser redirect site after payment has been handled. how can that? it feels missing since should standard setting using buttons. got it, url can specified data-return . <script src="paypal-button.min.js?merchant=stan-facilitator@merkwelt.com" data-button="buynow" data-name="new bot" data-quantity="1&q

i have table in have field requires 3 letters , 3 numbers (that have between values 2000 & 7000). i've been reading around, , i'm still not sure better way handle issue, whether can simple datatype, instance char(6), or if there has field contains 3 letters, , field contains 3 numbers check restriction ensure values of field between 2000 & 7000. any can offer me, glad. in advance you may have give more specificity requirements, sounds me single column best option -- if order matters. if letters , numbers have meanings separately, should in 2 columns. otherwise, you'll end having concatenate them together. char(6) fine long know always 6 characters exactly. can't enforce such specific limit 2000 7000 @ column level anyway (which 4 numbers, isn't it?)

i want define solidcolorbrush resource in wpf application (or rather in assembly several applications may refer to). in themes want color explicitly defined in resource dictionary making theme, in example classic theme want color system color. for example: aero.normalcolor.xaml : <solidcolorbrush x:key="{componentresourcekey typeintargetassembly={x:type l:myclass}, resourceid=mycolor}" color="#ff3399ff"/> classic.xaml: <solidcolorbrush x:key="{componentresourcekey typeintargetassembly={x:type l:myclass}, resourceid=mycolor}" color="{dynamicresource {x:static systemcolors.highlightcolorkey}}"/> this brush should available application name mycolor can re-defined on theme level. if defined above works should when color defined literal (i.e. when using aero theme), when referring systemcolors dynamic resource (in classic.xaml) exception say

i need generate random numbers between 20 , 50 5 increments. example, numbers must 20, 25, 30, 25, 50, 45 etc. difference between numbers should 5. i tried this: x<-floor(runif(50,20,50)) this gives me number between 20 , 50. there easy way in r? i think arun referring this: set.seed(123) sample(seq(from = 20, = 50, = 5), size = 50, replace = true) # [1] 30 45 30 50 50 20 35 50 35 35 50 35 40 40 20 50 25 20 30 50 50 40 40 50 40 # [26] 40 35 40 30 25 50 50 40 45 20 35 45 25 30 25 20 30 30 30 25 20 25 35 25 50

i developing (converting application db ms sql mysql) application using c#.net , mysql. c# code , stored procedure working perfect in ms sql when trying ingrate mysql getting parameter error. c# code below , mysql stored procedure running (tested in editor using call key work , parameter) public datatable alapvalidateuser(string email, string password,string type) { datatable dt = new datatable(); cmd = new mysqlcommand("useridvalidation"); cmd.commandtype = commandtype.storedprocedure; cmd.connection = cnn; string pass = reencryptpassword(password); mysqlparameter pramemail = new mysqlparameter("@v_emailid", email); pramemail.direction = parameterdirection.input; cmd.parameters.add(pramemail); mysqlparameter prampassword = new mysqlparameter("@v_password", pass); prampassword.direction = parameterdirection.input; cmd.parameters.add(prampassword);

we want write java 7 program boot (via 2 cmd line invokes) 2 separate jvm process instances. want these 2 processes communicate each other using native linux kernel shared-memory ipc resources. does have insight of these 2 approaches may have more merit? use java.nio.* api on /dev/shm use jni bridge c++ code makes native shmctl() system calls ? i vote "nio , /dev/shm". but before making final decisions, should consider other options, including clip: http://ambientideas.com/blog/index.php/tag/java/page/2/ http://ltsllc.com/talks/20090407_ipc.pdf inter jvm communication sockets, message queues , named pipes other ipc methods wouldn't dismiss out-of-hand. imho...

i'm trying write function gets string it's argument, searches if there 'p' or 'e' in it, splits onto separate strings, replaces " p " " 3.14... " , " e " " 2.71... ", converts strings onto double , multiplies converted strings. example, when argument " 123.45p4e9.2 ", function splits onto " 123.45 ", " p ", " 4 ", " e " , " 9.2 ", replaces characters constants: " 123.45 ", " 3.14... ", " 4 ", " 2.71... " , " 9.2 ", after converts of them onto double , multiplies: 123.45*3.14*4*2.71*9.2 . the problem when give string number, without 'p' or 'e' (for example " 2.4 " or " 32 "), returns 0. however, when give " e ", " p ", or " ep ", returns " 2.71... ", " 3.14... " or " 8.53... ", in in case works well. problem back, w
