i trying format 2 columns - 1 "general" , 1 "number 0.000," when second 1 formats, changes format of first column "number 0.000" well. if manually select columns , change format works fine. why macro changing format of both columns? here code snippet: range("c:c").select selection.numberformat = "general" range("d:d").select selection.numberformat = "0.000" try avoid using .select , might cause issues. try: range("c:c").numberformat = "general" range("d:d").numberformat = "0.000" that works me. the reason works if manually select range because when select range, .select part in macro use selected. avoiding .select helps ensure no matter cell/range have selected, use explicit range want (in case, range("c:c") , range("d:d")).

i'd try out writer monad in ghci. advised here , tried use stack manage ghc , packages, , avoid global installation. from fresh ubuntu 15.04 install, after installing stack: stack setup mkdir lyah && cd lyah stack new stack install mtl stack ghci ghci> import control.monad.writer not find module ‘control.monad.writer’ member of hidden package ‘mtl-2.1.3.1’. i understand pre-stack ghc-pkg used show/hide packages, i'm not sure how proceed here 'unhide' mtl package. edit .cabal file stack new created , add mtl build-depends section. part of file should this: build-depends: base >= 4.7 && < 5 , mtl then, stack build before stack ghci . by way, not use stack install install libraries - merely shortcut copy binaries. e.g. stack install hlint first build package , copy resulting binary ~/.local/bin/ . instead, add packages .cabal file, shown above, , use stack build installed.

what's difference between var = function () { this.x = function () { //do }; }; and var = function () { }; a.prototype.x = function () { //do }; the examples have different outcomes. before looking @ differences, following should noted: a constructor's prototype provides way share methods , values among instances via instance's private [[prototype]] property. a function's this set how function called or use of bind (not discussed here). function called on object (e.g. myobj.method() ) this within method references object. this not set call or use of bind , defaults global object (window in browser) or in strict mode, remains undefined. javascript object oriented language, i.e. object, including functions. so here snippets in question: var = function () { this.x = function () { //do }; }; in case, variable a assigned value reference function. when function called using a() , function's this ...
