is possible hide mouse cursor in windows 8.1 store app , move mouse screen center while moving? something (sdl code): sdl_showcursor(false); ... sdl_warpmouse(screen.width/2,screen.height/2); moving mouse pointer automatically center not possible in windows app. avoid fooling/cheating (not right word, still close enough) users in app. for example , if developer allowed before click of mouse button developer can hide mouse pointer place , move desired position , ads clicked , though user didn't wanted so! this goes windows 8/8.1 app design principles, apps can use limited resources of system.

oh, okay sooooo need method specify return of struct work? language meant c#! :) ok, doing wrong here. i've tried different things return random word array words keep getting errors. syntax appears similar i've read on. thanks. string getrandomwords() { wordbook[] words = new wordbook[26]; random = new random(); return words[random.next(0, words.length)]; your random syntax missing. should folows: random random = new random(); return words[random.next(0, words.length)]; also, function specifies returns string, return words[random], struct. hence error

i have android app in have multiple "categories" each items associated it. online electronics shop instance have categories such computers, printers, cameras etc. categories , each of have items in them. these categories should displayed "tabs" in top of screen can select tab show items associated it. works fine want able change category sliding left or right on screen well. as can see on image first tab selected. need when user swipes right, tab 2 selected instead , items in listview changed of course of category 2 (tab2). items (independent of category) have same design why use 1 listview. of problems have faced are: i don't know beginning how many tabs there going have created @ runtime. i can't create swipe listener on each item user not able swipe if items don't fill screen (as in example below there 4 items , empty area below have no listener) seems coul performance heavy maybe ? adding swipe listener on entire view containing list kin

how can see colors ggplot2 using discrete categories using given palette, "set1" or "set2" brewer? i.e. given set of categories colors used are? by default use hue_pal defaults. when use scale_x_brewer use brewer_pal defaults (both scales package). you'll many colors palettes have categories. e.g. (using defaults): f <- hue_pal(h = c(0, 360) + 15, c = 100, l = 65, h.start = 0, direction = 1) f(3) ## [1] "#f8766d" "#00ba38" "#619cff" f(9) ## [1] "#f8766d" "#d39200" "#93aa00" "#00ba38" "#00c19f" "#00b9e3" "#619cff" "#db72fb" ## [9] "#ff61c3" g <- brewer_pal(type="seq", palette=1) g(3) ## [1] "#deebf7" "#9ecae1" "#3182bd" g(9) ## [1] "#f7fbff" "#deebf7" "#c6dbef" "#9ecae1" "#6baed6" "#4292c6" "#2171b5" "#0

i coding 1 page lander know's little code. thinking of making user friendly on parts require customization, things <title></title> , headlines on website, urls in another php file. my idea make main file, lets call main_file.php make easy. in main_file.php want have: (for example) $title = "web page title here"; $headline = "headline here" $url1 = "http://a custom url here.com"; etc and have above echo 'd in right files. the goal of being user coding for, have edit 1 clear file, instructions etc needed. just that. your configuration file main_file.php right? your-application/main_file.php then, have master layout/template example: your-application/index.php in layout can include main file in first line: <?php include ('main_file.php'); ?> <!-- rest of code below --> <!doctype html> <html lang="en"> <head> <meta charset="utf-8">

if using fgets(line, maxline, stdin) function in loop, should zero-out line each time before new iteration? meaning have smth char *line = calloc(maxline+1, 1); while (fgets(line, maxline+1, stdin)) { ... } is required reallocate or zero-out line char string before next call of fgets? thank no. fgets guarantees 0 termination on successful read. loop condition handles unsuccessful case. completeness, should check calloc worked though.

in code, output of 1 query. if pass next query in entry box, previous output in textbox remains unchanged , not getting output of new query. coding:- import tkinter tk import re class sampleapp(tk.tk): def __init__(self): tk.tk.__init__(self) self.l1 = tk.label(self, text="enter query") self.l1.pack() self.entry = tk.entry(self) self.button = tk.button(self, text="get", command=self.on_button) self.button.pack() self.entry.pack() self.text = tk.text(self) self.text.pack() def on_button(self): s1=(self.entry.get()) open("myxml.txt","rb")as f: row = f.readlines() i, r in enumerate(row): if s1 in r: x in range(i-3,i+4): s = row[x] m = re.sub(r'<(\w+)\b[^>]*>([^<]*)</\1>', r'\1-\2', s)

cheshire's custom encoders seem suitable problem , wrote little helper function: (defn add-rec-encoder [rec type-token] (add-encoder rec (fn [rec jg] (.writestring jg (str (encode-map (assoc rec :type type-token) jg)))))) (defrecord [a]) (add-rec-encoder "a") (encode (->a "abc")) but produces strange trailing "" . => {"a":"abc","type":"a"} "" what causing this? , there approach worth considering (i need able decode record based on type-token)? (encode-map ... jg) directly writes encoded map json generator jg , returns nil . this means that, call writestring actually: (.writestring jg (str nil)) which, since (str nil) "" , encode , append json generator. correct encoder logic be: (defn add-rec-encoder [rec type-token] (add-encoder rec (fn [rec jg] (encode-map (assoc rec :type type-token) jg))))

i ran simple problem. installed this package , wish sluggify entire model. i have upgraded m model definition instructed: protected $sluggable = array( 'build_from' => 'fullname', 'save_to' => 'slug', ); public function getfullnameattribute() { return $this->firstnames .

ok. i've been looking @ supplied answers, , seem specific. need know in general sense. issue i have couple of js objects. use json.stringify compare them (see if object "dirty"). however, stringify renders object set in memory, takes whatever order properties of object happen in. if delete property, restore it, change order. i'll show simple html example in second. want, restore section before section. i'm wondering if there basic, browser-generic way that. example <html> <head><title>test js</title></head> <body> <dl> <dt><strong><big>before:</big></strong></dt> <dd><em><strong>object a:</strong> <span id="obja1"></span></em></dd> <dd><em><strong>object b:</strong> <span id="objb1"></span></em><
