  • which is the most secure way to check variables type javascript

    - by mck89
    Hi, i need to check the type of a variable in javascript, i know 3 ways to do it: instanceof operator: if(a instanceof Function) typeof operator: if(typeof a=="function" toString method (jQuery uses this): Object.prototype.toString.call(a) == "[object Function]" Which is the most secure way to do type checking beetween these solutions? and why? Please don't tell me that the last solution is better only because jQuery uses that.

  • Modifying multiplying calculation to use delta time

    - by Bart van Heukelom
    function(deltaTime) { x = x * 0.9; } This function is called in a game loop. First assume that it's running at a constant 30 FPS, so deltaTime is always 1/30. Now the game is changed so deltaTime isn't always 1/30 but becomes variable. How can I incorporate deltaTime in the calculation of x to keep the "effect per second" the same?

  • How to get IP address of your application server

    - by Jason
    I need to be able to find the IP address of the server the page is currently executing on.

Is there a CGI variable or some way in ColdFusion to determine what the IP address is of the host server?

  • Try-Catch or Check Length? C# XNA

    - by Shaded
    I was just wondering which would be cheaper, using a try catch block for index out of bounds or checking the length of a multi dimensional array and comparing values? I have a feeling it's the length, since I can store the length in a variable and then just do if's which are relatively cheap. I'm just not sure how expensive try-catch is. Thanks!

  • Launch Scala REPL programatically?

    - by David Crawshaw
    I would like to launch a Scala Swing application from the command line, then after the application is started, drop into the Scala REPL to use as a control interface. Ideally I would also like to pre-bind some variable names. Even better would be using a Java2D terminal emulator for the REPL, but I couldn't find anything appropriate. Does the Scala REPL have a public API?

  • Best Way to Include Debug Code?

    - by stormin986
    I am programming Android applications, and the best way here may or may not be the same as Java in general. I simply want to be able to set a debug flag that will only execute certain portions of code when it's set to true––equiv to C++ setting a preprocessor #define DEBUG and using #ifdef DEBUG. Is there an accepted or best way to accomplish this in Java? Right now I'm just going to set a variable in my Application object, but I don't imagine this is the best way.

  • Pass encrypted querystring between php and asp.net (c#)

    - by Paul
    I need to pass a single variable in a querystring from one application (in PHP) to another (in ASP.NET). It's a one way transfer...That is I need to encrypt it in PHP and decrypt it in ASP.NET (c#). I'm barely a newbie on PHP and I'd like not to have to do more than add a tag to the page that needs to do the passing. The data will be anywhere from 5 - 15 characters..only letters and numbers. Thanks!

  • Microsoft Mouse and Keyboard Center Needed for Keyboard but Doesn't Support Mouse

    - by eljay
    I recently built a new computer (running Win7 Pro 64-bit) that includes the Microsoft Sidewinder X4 Keyboard. To make use of all the extra features of this keyboard I need the Mouse and Keyboard Center. I just ran Windows Update for the first time on this system and the Mouse and Keyboard Center was included in the update. I'm left-handed and before the update I had the mouse set up for lefty use. Now after the update, it's been set to righty use and the original mouse control panel applet no longer allows the assignment of buttons. For that there's a link to the Mouse and Keyboard Center which does not support my oldish mice. (I have an IntelliMouse Optical and a Creative Mouse Lite Pro.) So I need the new utility for my keyboard, but I have to be right-handed to use my mouse? Really! I tried changing HKCU\Control Panel\Mouse\SwapMouseButtons to 1, but a reboot set it back to 0. Is there some way I can change my mouse back to left-handed? Thanx -eljay

  • How can you remove a field from a word document?

    - by Kevin van Zanten
    Dear reader, I'm working on a project where the user can insert data into a document using fields, document properties and variables. The user also needs to be able to remove the data from the document. So far, I've managed to remove the document property and variable, but I'm not sure how I would go about removing the field (that's already inserted into the document). Please advise. Yours sincerely, Kevin

  • How to add a context processor from a Django app

    - by Edan Maor
    Say I'm writing a Django app, and all the templates in the app require a certain variable. The "classic" way to deal with this, afaik, is to write a context processor and add it to TEMPLATE_CONTEXT_PROCESSORS in the settings.py. My question is, is this the right way to do it, considering that apps are supposed to be "independent" from the actual project using them? In other words, when deploying that app to a new project, is there any way to avoid the project having to explicitly mess around with its settings?

  • Multiple Cookie Generation Issue

    - by Shannon
    Hi all, jQuery newbie here. I need to be able to set multiple cookies within the code without have to change out this variable each and every time. Is there any way to make this code generate unique cookies for different pages? As it is now, I'm having to rename that variable for each page that the jQuery animations exist on. (sbbcookiename) Background on the issue: We are having issues with the sliders not autoplaying once one has already been triggered, due to it the cookie having been cached. Thanks for your help. (function(){ jQuery.noConflict(); var _TIMEOUT= 1000, initTimer= 0, sbLoaded= false, _re= null ; initTimer= setTimeout(initSlider, _TIMEOUT); jQuery(document).ready(initSlider); function initSlider(){ if(sbLoaded) return; if (jQuery('#campaign_name').length > 0) { var sbbcookiename = jQuery('#campaign_name').attr('class'); } else { var sbbcookiename = "slider728x90"; } var slideTimeout //timer ,sbTrigger = jQuery('#slidebartrigger') //convenience ,sbFirstSlide = (document.cookie.indexOf(sbbcookiename) == -1) //check cookie for 'already seen today' ; clearTimeout(initTimer); sbLoaded= true; function toggleSlideboxes(){ if(slideTimeout) clearTimeout(slideTimeout); var isDown = sbTrigger.is('.closeSlide'); jQuery('#slidebar')['slide' + (isDown ? 'Up' : 'Down')]((isDown ? 1000 : 1000), function(){ if(sbFirstSlide){ //if 'first time today' then clear for click-to-replay sbTrigger.removeClass('firstSlide'); sbFirstSlide = false; } sbTrigger[(isDown ? 'remove' : 'add') + 'Class']('closeSlide').one('click', toggleSlideboxes); if(!isDown) slideTimeout = setTimeout(toggleSlideboxes, 4000); }); } if(sbFirstSlide){ //not seen yet today so set a cookie for expire tomorrow, then toggle the slide boxes... var oneDay = new Date(); oneDay.setUTCDate(oneDay.getUTCDate()+1); oneDay.setUTCHours(0, 0, 0, 0); //set to literally day-by-day, rather than 24 hours document.cookie=sbbcookiename+"=true;path=/;expires="+oneDay.toUTCString(); toggleSlideboxes(); }else{ //already seen today so show the trigger and set a click event on it... sbTrigger.removeClass('firstSlide').one('click', toggleSlideboxes); } } })();

  • Why does this JSON.parse code not work?

    - by SuZi
    I am trying to pass json encoded values from a php script to a, GnuBookTest.js, javascript file that initiates a Bookreader object and use the values i have passed in via the variable i named "result". The php script is sending the values like: <div id="bookreader"> <div id="BookReader" style="left:10px; right:10px; top:30px; bottom:30px;">x</div> <script type="text/javascript">var result = {"istack":"zi94sm65\/BUCY\/BUCY200707170530PM","leafCount":"14","wArr":"[893,893,893,893,893,893,893,893,893,893,893,893,893,893]","hArr":"[1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155]","leafArr":"[0,1,2,3,4,5,6,7,8,9,10,11,12,13]","sd":"[\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\"]"}</script> <script type="text/javascript" src="http://localhost:8080/application/js/GnuBookTest.js"></script> </div> </div> and in the GnuBookTest.js file i am trying to use the values like: br = new BookReader(); // Return the width of a given page. br.getPageWidth = function(index) { return this.pageW[index]; } // Return the height of a given page. br.getPageHeight = function(index) { return this.pageH[index]; } br.pageW = JSON.parse(result.wArr); br.pageH = JSON.parse(result.hArr); br.leafMap = JSON.parse(result.leafArr); //istack is an url fragment for location of image files var istack = result.istack; . . . Using JSON.parse as i have written it above loads the Bookreader and uses my values correctly in a few web-browsers: Firefox, IE8, and desktop-Safari; but does not work at all in mac-Chrome, mobile-Safari, plus older versions of IE. Mobile safari keeps giving me a reference error msg: can't find variable: JSON. The other browsers just do not load the Bookreader and show the "x" instead, like they did not get the values from the php script. Where is the problem?
