i have rootviewcontroller create mainviewdownload instance , call method of instance. mainviewdownload *download = [[mainviewdownload alloc] init]; [download loadmainviewimages]; how can know when loadmainviewimages finished ? call loadmainviewimages rootviewcontroller loadmainviewimages calls method inside mainviewdownload class (lets method2), , method2 calls again method3. so, there way know when loadmainviewimages finished (actually when method3 finished since last called). if you're not multithreading, i.e. starting method runs on separate thread loadmainviewimages , methods executed sequentially. once loadmainviewimages returns can sure "in it" executed. how methods work. edit better formatting of comments: mainviewdownload.h @protocol mainviewdownloaddelegate; @interface mainviewdownload @property (nonatomic, weak) nsobject<mainviewdownloaddelegate> *delegate; @end @protocol mainviewdownloaddelegate - (void)downloaddidfinish:(mainvi

i have created simple website , have form asks user input email address receive future updates me. what best way save these emails. not anticipating having many thought email them myself every time submits theirs. know how using asp.net , gmail. questions are: 1) there way accomplish using html , javascript , better having use asp.net 1 thing on site (i haven't looked web hosting have thought cheaper use html , javascript)? 2) there better way go have missed? thanks rob is there way accomplish using html , javascript no is there better way go have missed? use real mailing list software or third party mailing list service. save having maintain list manually (which error prone) , (especially if use decent third party service) reduce number of indicators emails trigger in spam filters.

probably simple answer don't understand principles of jquery enough work out. i have this: $(".remove", document.getelementbyid(itemsareaid)).live("click", function(){ which want migrate .on() i tried doing this var selectedels = $(".remove", document.getelementbyid(itemsareaid)); $(document).on('click',selectedels, function(e){ but doesn't work. anyone explain i'm doing wrong? and if possible why solution didn't work can understand. many thanks, paul the optional selector on() must string . you're providing jquery object ( selectedels ). instead, use string selector .remove directly. rather targeting document , use itemsareaid ; $('#' + itemsareaid).on('click', '.remove', function ()); if wanted target document , use descendant selector along itemsareaid , .remove , this; $(document).on('click', '#' + itemsareaid + ' .remove', functio

i'm trying avoid dll hell problem , users having install redistribution packages in case don't have dlls. is recommended compile application statically? it depends. if program small, , want able drop single executable onto machine , run it, static linking appropriate , simplest thing do. if program larger, or if need installer anyway (to deploy multiples files, set registry keys, etc.), may link dynamically, can substantially reduce size of executable. can avoid dll hell installating necessary, redistributable run time dlls in same directory executable. if want go pro, can create msi-based installer includes merge modules run time libraries project requires. do not compile dynamically , expect user either have dlls or install vcredist package. that's difficult support , it's pain users. there additional considerations if you're thinking linking own dll static run-time library. if statically link run time, can end of having multiple instan

i'd run query in go using "database/sql" package: select id, name users id in (1,2,3,4); how use variable substitution in query command? e.g., want (which of course doesn't work): db.query("select id, name users id in (?)", []int{1,2,3,4}) @volker suggests in comments database drivers may able expand slice you. driver can handle slice elements individually, however: db.query("select id, name users id in (?, ?, ?, ?)", 1, 2, 3, 4) of course, you'd need know how many elements going in slice when write that, isn't case. generating correct number of question marks simple enough , gives general solution: ints := []interface{}{1,2,3,4} marks := strings.repeat("?,", len(ints) - 1) + "?" db.query("select id, name users id in (" + marks + ")", ints...) if slice might empty, you'll have handle somehow.

i have isabelle proof structured follows: proof (cases "n = 0") case true (* lots of stuff here *) show ?thesis sorry next case false (* lots of stuff here *) show ?thesis sorry qed the first case several pages long, when reading second case it's no longer clear casual reader, not myself, false refers to. (well, is , not reading, in interactive environment: if, e.g., in isabelle/jedit, place cursor after case false , you'll see n ≠ 0 under "this" in output panel.) so there syntax allows making assumption of "false" case explicit, reader neither has interact ide, nor scroll proof keyword, can see assumption right in place? in case proof becomes more readable stating assumption of each case explicitly: proof cases assume "n = 0" show ?thesis sorry next assume "n ≠ 0" show ?thesis sorry qed

i trying define few global variables should available functions initialize main program. can me syntax? please note still bit beginner c++ classes etc. need run same copy of program multiple times , don't want have same shared class across multiple instances of program - need ensure create new class in main body. wanted mention - printvars - pre-built function me , don't have control on passing pointer variables - can use global variables in function. class gvars { public: int x=0; int y=0; gvars() {} ~gvars() {} }; std::unique_ptr<gvars> *g=null; // must pointer class //i can't pass parameters function //only have control on body of program access global vars void printvars() { std::cout << (*g).x << " " << (*g).y << std::endl; } int main() { if (g==null) { g=new gvars(); // critical - create new class here } (*g).x=10; (*g).y=20; printvars(); // expected output : 10 20 delete

when running regression in r, order returned coefficients? example: coef(lm(y ~ x + z, data=data.frame(x=1:10, y=10:1, z=1:5))) is guaranteed coefficient associated x returned before coefficient associated z ? order mean order in vector of returned coefficients. reason matters me test linear hypothesis coefficients in model , therefore order of coefficients in variance covariance matrix returned vcov , actual estimates returned coef matters. index name, not position. right answer. coef(lm(y ~ x+z, data=data.frame(x=1:10, y=10:1, z=1:5)))['x'] ## x ## -1 coef(lm(y ~ x+z, data=data.frame(x=1:10, y=10:1, z=1:5)))['z'] ## z ## -1.855301e-16 and both of them, in desired order: coef(lm(y ~ x+z, data=data.frame(x=1:10, y=10:1, z=1:5)))[c('x', 'z')] ## x z ## -1.000000e+00 -1.855301e-16

i trying make image editing application in java using mvc design pattern. so, event handling in controller, state , operations relevant state stored in models, , user sees stored in views. when open image, there zoom box displays zoom level of image being displayed. zoom automatically calculated when first rendered in paintcomponent() (see step #3). when open image, want zoom level set calculated be. the problem zoom level shows 0 , , know why. let me explain: 1. the actionlistener for open menu item fired in jpscontroller: class menubarfileopenlistener implements actionlistener { public void actionperformed(actionevent event) { file filechooserreturnvalue = view.showandgetvalueoffilechooser(); if (filechooserreturnvalue != null) { try { // irrelevant code omitted view.adddocument(newdocument); } catch(ioexception ex) { ex.printstacktrace(); } } } } 2.
