in win7, want pass arbitrary integer return code or errorlevel html/javascript file batch file started it. is there way can use javascript in html program set return or errorlevel code? edit: woohoo! thanks! yeah, ie executes sample hta code. that leaves question of how can manipulate errorlevel code out of javascript in hta program. wikipedia blurb says can control system hta file, javascript doesn't seem have commands so, though hta allows it. i still feel 1 of paralyzed 'locked-in' patients have communicate trying blink eyes.

i made project setuptools , want test tox . listed dependencies in variable , added setup() parameter ( tests_require , extras_require ). project needs install of dependencies listed in tests_require test pip install not installing them. i tried did not work: install_command = pip install {opts} {packages}[tests] how can install test dependencies without having manage multiple dependency lists (i.e. having dependencies listed in both test_requirements.txt , tests_require variable)? i've achieved committing slight abuse of extra requirements . there trying extras syntax, tests_require deps aren't automatically available way. with setup.py this: from setuptools import setup test_deps = [ 'coverage', 'pytest', ] extras = { 'test': test_deps, } setup( # other metadata... tests_require=test_deps, extras_require=extras, ) you can test dependencies installed extras syntax, e.g. project root directory:...

there n number of students in class. teacher tells 1 secret each student. way share secret through phone call. using divide , conquer, design algorithm find minimum number of phone calls required each student secrets. one of friend asks me this. put time make sketch i.e. have array of students , i'll break recursively until have 1 student , upon joining them i'll make count call has been made between these two. while combining 2 pairs i'll count 2 calls , on. point troubling me or may here missing something. x1 x2 (1 call) x3 x4 (1 call) x1 -----> x3 x2 -----> x4 (2 more calls) any assistance appreciated. the optimum scheme n>=4 people share n pieces of information 2n-4 shown in paper . the divide , conquer approach problem illustrated follows: for 4 persons a, b, c , d, say, take conversations ab, , cd, followed ac , bd. every additional person p, schedule 1 conversation ap, before a, b, c , d interc...

i'm working on project involves creating pages external source. since these external sources variable in nature, cannot strictly define schema use. did research , learned mongoose's mixed schema type , created following model: var pagetemplate = new mongoose.schema( { }, { strict: false } ); during import process, perform upsert operation update existing entries , insert new ones: pagetemplate .findoneandupdate( { slug: page.slug }, page, { upsert: true } ); everything works great far. problem arises when later try fetch entries. when console.log entire object, expect--the entire object. reason, when go access single property, undefined . pagetemplate.findone( { slug: slug }, function(err, page) { console.log(page); // prints entire object console.log(page.slug); // undefined } ) have misunderstood how mixed schemas supposed b...

not sure if appropriate forum this, need guidance further down road wpf. i've used telerik winform controls years , have mixed feelings them. good, nested, have steep learning curve, , don't perform best. example, working radwindow in wpf designer, it's slow compared native wpf controls. i caliburn.micro mvvm framework , mahapps metro styles, keep same , feel ribbon bar i'd need use third party tool (like fluent) or use microsoft ribbon view control , figure out how use templates , styles myself (or find existing metro template it). i tried combine telerik , caliburn had trouble getting them work. there caliburn telerik library based on caliburn micro 1.5.2 , i'm trying use caliburn.micro 2.0.2. problem aero-looking full window title bar , frame wrapped around telerik styled window. i don't know enough conventions , such make work together. , frankly, not sure it's worth trouble. i'm looking more streamlined approach lessens dependence on pri...

using ggplot2 1.0.0 , followed instructions in below post figure out how plot percentage bar plots across factors: sum percentages each facet - respect "fill" test <- data.frame( test1 = sample(letters[1:2], 100, replace = true), test2 = sample(letters[3:8], 100, replace = true) ) library(ggplot2) library(scales) ggplot(test, aes(x= test2, group = test1)) + geom_bar(aes(y = ..density.., fill = factor(..x..))) + facet_grid(~test1) + scale_y_continuous(labels=percent) however, cannot seem label either total count or percentage above each of bar plots when using geom_text . what correct addition above code preserves percentage y-axis? staying within ggplot, might try ggplot(test, aes(x= test2, group=test1)) + geom_bar(aes(y = ..density.., fill = factor(..x..))) + geom_text(aes( label = format(100*..density.., digits=2, drop0trailing=true), y= ..density.. ), stat= "bin", vjust = -.5) + facet_grid(~t...
