  • Running a custom VirtualPathProvider with a PreCompiled website

    - by epilog
    Hi, currently I have a custom VirtualPathProvider in a Asp.net MVC web application. This VirtualPathProvider checks the Area from the route "/{Area}/{Controller}/..." and uses the NameSpace.{Area}.Main.dll module to return the views that are contained in that assembly as Embedded Resources. This works great and I don't have to deploy any ascx, js, css files. Now my problem is this: I would like to precompile the aspx and ascx files in the assembly and instead of having the views as embedded resources I would have the view class with all the Response.Write and dings and dongs. I can precompile the views using the aspnet_compiler but I keep getting an error when ever the ViewEngine tries to find the view and fails. My main goal is to have a way for the first time usage of a certain view/usercontrol would be faster and don't wait for the compilation to happen. This is a requirement since the application could be grouped into plugins and this plugins be deployed into the Bin directory. Any thoughts? With best regards Carlos Sobrinho

  • Firefox throwing a exception with HTML Canvas putImageData

    - by mr.doob
    So I was working on this little javascript experiment and I needed a widget to track the FPS of it. I ported a widget I've been using with Actionscript 3 to Javascript and it seems to be working fine with Chrome/Safari but on Firefox is throwing an exception. This is the experiment: Depth of Field This is the error: [Exception... "An invalid or illegal string was specified" code: "12" nsresult: "0x8053000c (NS_ERROR_DOM_SYNTAX_ERR)" location: "http://mrdoob.com/projects/chromeexperiments/depth_of_field__debug/js/net/hires/debug/Stats.js Line: 105"] The line that is complaning about is this one: graph.putImageData(graphData, 1, 0, 0, 0, 69, 50); Which is a crappy code to "scroll" the bitmap pixels. The idea is that I only draw a few pixels on the left of the bitmap and then on the next frame I copy the whole bitmap and paste it on pixel to the right. This error usually is thrown because you're pasting a bitmap bigger than the source and it's going off the limits, but in theory that shouldn't be the case as I'm defining 69 as the width of the rectangle to paste (being the bitmap 70px wide). And this is full code: var Stats = { baseFps: null, timer: null, timerStart: null, timerLast: null, fps: null, ms: null, container: null, fpsText: null, msText: null, memText: null, memMaxText: null, graph: null, graphData: null, init: function(userfps) { baseFps = userfps; timer = 0; timerStart = new Date() - 0; timerLast = 0; fps = 0; ms = 0; container = document.createElement("div"); container.style.fontFamily = 'Arial'; container.style.fontSize = '10px'; container.style.backgroundColor = '#000033'; container.style.width = '70px'; container.style.paddingTop = '2px'; fpsText = document.createElement("div"); fpsText.style.color = '#ffff00'; fpsText.style.marginLeft = '3px'; fpsText.style.marginBottom = '-3px'; fpsText.innerHTML = "FPS:"; container.appendChild(fpsText); msText = document.createElement("div"); msText.style.color = '#00ff00'; msText.style.marginLeft = '3px'; msText.style.marginBottom = '-3px'; msText.innerHTML = "MS:"; container.appendChild(msText); memText = document.createElement("div"); memText.style.color = '#00ffff'; memText.style.marginLeft = '3px'; memText.style.marginBottom = '-3px'; memText.innerHTML = "MEM:"; container.appendChild(memText); memMaxText = document.createElement("div"); memMaxText.style.color = '#ff0070'; memMaxText.style.marginLeft = '3px'; memMaxText.style.marginBottom = '3px'; memMaxText.innerHTML = "MAX:"; container.appendChild(memMaxText); var canvas = document.createElement("canvas"); canvas.width = 70; canvas.height = 50; container.appendChild(canvas); graph = canvas.getContext("2d"); graph.fillStyle = '#000033'; graph.fillRect(0, 0, canvas.width, canvas.height ); graphData = graph.getImageData(0, 0, canvas.width, canvas.height); setInterval(this.update, 1000/baseFps); return container; }, update: function() { timer = new Date() - timerStart; if ((timer - 1000) > timerLast) { fpsText.innerHTML = "FPS: " + fps + " / " + baseFps; timerLast = timer; graph.putImageData(graphData, 1, 0, 0, 0, 69, 50); graph.fillRect(0,0,1,50); graphData = graph.getImageData(0, 0, 70, 50); var index = ( Math.floor(Math.min(50, (fps / baseFps) * 50)) * 280 /* 70 * 4 */ ); graphData.data[index] = graphData.data[index + 1] = 256; index = ( Math.floor(Math.min(50, 50 - (timer - ms) * .5)) * 280 /* 70 * 4 */ ); graphData.data[index + 1] = 256; graph.putImageData (graphData, 0, 0); fps = 0; } ++fps; msText.innerHTML = "MS: " + (timer - ms); ms = timer; } } Any ideas? Thanks in advance.

  • JavaScript: 'textarea.value' not working in IE?

    - by pete
    Hi! A few hours ago, I was instructed how to style a specific textarea with JS. The following piece of code (thanks again, Mario Menger) works like a charm in Firefox but unfortunately nothing happens in Internet Explorer (7 tested only so far). var foo = document.getElementById('HCB_textarea'); var defaultText = 'Your message here'; foo.value = defaultText; foo.style.color = '#888'; foo.onfocus = function(){ foo.style.color = '#000'; if ( foo.value == defaultText ) { foo.value = ''; } }; foo.onblur = function(){ foo.style.color = '#888'; if ( foo.value == '' ) { foo.value = defaultText; } }; I've already tried to replace 'value' by 'innerHTML' (for IE only) but to no effect. Any suggestions? TIA

  • Event Capturing vs Event Bubbling

    - by Rajat
    I just wanted to get the general consensus on which is a better mode of event delegation in JS between bubbling and capturing. Now I understand that depending on a particular use-case, one might want to use capturing phase over bubbling or vice versa but I want to understand what delegation mode is preferred for most general cases and why (to me it seems bubbling mode). Or to put it in other words, is there a reason behind W3C addEventListener implementation to favor the bubbling mode. [capturing is initiated only when you specify the 3rd parameter and its true. However, you can forget that 3rd param and bubbling mode is kicked in] I looked up the JQuery's bind function to get an answer to my question and it seems it doesn't even support events in capture phase (it seems to me because of IE not support capturing mode). So looks like bubbling mode is the default choice but why?

  • Fit Lightbox container in window if image is larger

    - by Bobe
    I'm just looking for a simple way to set the max width and height of the Lightbox container and image based on the window size if the image is larger than the current window size. So say the image is 2000x1200 and the window is 1280x1024, then the max-height and max-width of div.lb-outerContainer and img.lb-image should be set to $(window).height() - 286, $(window).width() - 60 and $(window).height() - 306, $(window).width() - 80 respectively. I'm just having a bit of trouble determining where to go about implementing these rules. Do I do it in the lightbox.js file? If so, where? Would it be acceptable to just throw in some script on the page it's used on?

  • input type text and onKeyDown not working under IE

    - by dygi
    Hi there. I am writing a WWW application, it has to run under IE. I have the problem with the code that runs under FF, but i can't get it running under IE. // JS code function test() { if (window.event.keyCpde == 13) window.location.href.ssign("myPage.php"); } I've tried some similar ways around window.location and location.href, also document.location. I've read that IE has problems with that, so i ask for a solution. The goal is, that page reloads after typing in some text into <input type='text' name='item_code' onKeyDown='test()'> and click enter. So the result is similar to pressing submit type button below the text input. Within IE it reloads the same page and nothing happens. In FF it correctly works.

  • Ideas for web development practical jokes?

    - by Ellie P.
    I am a web developer for a Django-based site for a student organization, and I have the opportunity to make the website temporarily absurd for a day of general campus-wide debauchery and chaos (long story, doesn't matter.) What are your best ideas for web development practical jokes (that you could never use in the real world)? For example, one idea we had was to use a client-side script to convert each character to its upside down equivalent in Unicode, si?? ??i? ?ui????os. I'm not necessarily looking for Django-specific solutions. I imagine most of these things would happen on the front-end. I am also quite aware that usability will suffer considerably--the point is to be fun for a day, and there will always be a link to the normal version of the site. Also, everything must be relatively cosmetic and easily reversible--I'm happy to swap out static CSS/JS/HTML/templates/images, and even temporarily add a django view, but no messing with the data level!

  • How to use the Rhino javascript engine in an applet

    - by Robber
    For my java program I'm using Rhino to execute JS scripts. Now I'm trying to convert it to an applet which works great, except that everytime it's calling evaluateString(...) the JVM throws an AccessControlException. After some (a lot) of research I found out that this is caused by Rhino's custom classloader. My problem is that after hours of googling I still can't find a way to stop Rhino from trying to load it's own classloader. I hope someone can help me...

  • What's the best JSF implementation?

    - by Jeff
    Hey everyone, I currently have a medium size Java web application sitting on top of Spring MVC. As much as I like (no sarcasm) coding straight HTML, CSS and JS, it's not possible for me to develop as fast as I'd like. I'm looking at different RAD frameworks to speed up my development. I'm looking at JSF implementations and component libraries, Flex, GWT and a few others. As of now, Apache MyFaces (with ICEFaces) seems to be the front runner in my mind, but I'm curious to find out what you all think of that specific implementation and if the Sun implementation is any better? What's important to me is something that is stable, has an active community and that it doesn't look like there is another technology in the near future that is going to eclipse JSF (which would drive me to use a different RAD framework). Thanks in advance for the responses.

  • GWT Acegi alternative

    - by DroidIn.net
    I'm starting new project. The client interface is based on GWT (and GXT) I have no say it's predetermined. However I can pick and choose as far as server side so I can have some fun and hopefully learn something new in the process. Some requirements are : Exchange with server will be through use of JSON, most if not all of UI will be generated by GWT (JS) on the client, so the client/serve exchange will be limited to data exchange as much as possible No Hibernate (it's not really supported on the proprietary db I will be connecting to). In the past projects people would use JDBC or iBATIS Some sort of IoC (I'm thinking Guice just to stick with Google) Some sort of Security framework based on LDAP. In the past we would use Spring security (Acegi) but it wasn't ideal and we had to customize it a lot So basically should I stick with tried-and-true Spring/Acegi or try something based on Guice? And what that "something" would be and how mature is it?

  • Clob as param for PL/SQL Java Stored Procedure

    - by JDS
    I have a java stored procedure that takes in a clob representing a chunk of javascript and mins it. The structure of the function calling the JSP is as follows: function MIN_JS(pcl_js in clob) return clob as language java name 'JSMin.min(oracle.sql.CLOB) return oracle.sql.CLOB'; In the actual JSP, I have the following: import oracle.sql.CLOB; public class JSMin { ... public static min(CLOB js) { ... } The problem I'm having is that whenever I pass a clob to JS_MIN, it is always interpreted as null inside the JSP. I've checked the clob before calling JS_MIN annd it definitely has contents. Any ideas as to what I'm missing? Any help is greatly appreciated.

  • Javascript Intellisense not working on Visual Studio 2010 Ultimate (Windows 7 x64)

    - by emzero
    Hi guys, I've just got the new Visual Studio 2010 Ultimate and Javascript Intellisense is not working on .aspx/.ascx files inside blocks. It does work on external .js files. After VS2010 setup, it asked me if I wanted to import the settings from previous VS version (I have VS2008 SP1 installed), I say yes. I've tried resetting the settings like explained here. Didn't work. I've also installed Resharper 5. I thought it might be conflicting, so I tried suspending it like it says here. Didn't work. Anyone experiencing the same issue? I really want javascript/jQuery intellisense =(

  • Error "window" is not defined when loading Protovis from javax.script?

    I am loading Protovis using javax.script: ScriptEngineManager factory = new ScriptEngineManager(); ScriptEngine engine = factory.getEngineByName(scriptEngine); engine.eval(new java.io.FileReader("protovis-d3.1.js")); But I get the following exception: Exception in thread "main" javax.script.ScriptException: sun.org.mozilla.javascr ipt.internal.EcmaError: ReferenceError: "window" is not defined.

  • How to get scrollTop of page afer browser scrolled such page?

    - by Marco Demaio
    I know how to get the scrollTop of a page, I use this simple JS function (code copied around): function GetScrolledTop() { //I never work in IE quirkmode, I always use DOCTYPE as 1st line, so I don't need to test for document.body.scrollTop return self['pageYOffset'] || document.documentElement.scrollTop; } This works and my problem is the following: I tried to add it in the page onload event <body onload="alert(GetScrolledTop());"> On page load I get ZERO (which make sense), but the problem is that I get ZERO even if I scroll the page and then reload it without touching the scrollbar. It seems like the browser does: loads page calls my GetScrolledTop() (so obviously shows ZERO) then scrolls the page to where it was before. Do you know how to get the scolledTop after the step 3? I mean how to get the scrolledTop AFTER the browser scrolled the page? (maybe without using a timer) Thanks!

  • Cross domain cookie reading/setting cross browsers

    - by Rac123
    I know there are already a few threads available here on this subject but I want others' opinion on this. There are two ways to set/read the cross domain cookies: Creating IFrame on A.com pointing to a page on B.com which creates the cookie and pass that information by creating another IFrame on B.com side pointing to A.com, either using window.name or in location.href.hash A.com page makes a XHR/JSONP call to B.com web service/page that has the following headers and it also sets up the cookie and returns the value. AddHeader("p3p", "CP=\"IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT\"") As we don't have postMessage available across all the browsers, I believe we have to go with one of the cases mentioned above. My question is which is a better way (cleaner) and why to implement for cross browser. Using any other JS framework is out of scope of this discussion. If there's another better way, please mention here! Thank you for your intelligent input in advance! :)

  • Does setting an onload event for a <script> tag work consistently in modern browsers?

    - by Matchu
    I observe that placing the following in an external script file has the desired effect in my copies of Firefox and Google Chrome: var s = document.createElement('script'); s.setAttribute('type', 'text/javascript'); s.setAttribute('src', 'http://www.example.com/external_script.js'); s.onload = function () { doSomethingNowThatExternalScriptHasLoaded } document.getElementsByTagName('body')[0].appendChild(s); It adds a an external script tag to them DOM, and attaches a function to the tag for when the script has loaded. I'm having trouble testing in Internet Explorer right now, but I'm not sure if it's related to that addition in particular, or something else. Does this method work in the more modern versions of other browsers, including IE7/8? If not, how else could I go about this?

  • How can I turn on DynamicCompression feature of IIS programmatically?

    - by LockeVN
    I'm making an installer program for my web application. My web application uses CSS and JS heavily, so I want to enable both Static and Dynamic HttpCompression for IIS7/7.5. It needs 2 steps: I can modified the web.config, put <httpcompression> tag, it's ok. DynamicContentCompression must be turned on in Windows Feature to make httpCompression work. Static HttpCompression is enable by default in IIS7 and IIS7.5, but Dynamic HttpCompression is not enable by default (although it's available). I can do manually by turn on: Start/ControlPanel/ProgramsAndFeatures/TurnWindowsFeatures on or Off/IIS/WWW Service/Performance features/Dynamic Content Compression, but How can I programmatically turn it on that Windows Feature? I can use PowerShell, C# in my installer. Any idea how I might be able to do this? Thanks.

  • Jquery JCarousel, itemLastInCallback how to change out the controls

    - by TJ Sherrill
    I am new to js and Jquery other than plug and play scripts and plugins. I have Jcarousel running great on a Ruby on Rails site and I need to use the itemLastInCallback method to change out the next and prev buttons. Basically if the end user clicks through to the last item in a carousel, the next button would become a link to the next carousel. <%= link_to (image_tag 'scroll_right.png'), @next_group % is the code I need to render in the end. So something like: if this is not the last item in the carousel button is normal jcarousel next button else <%= link_to (image_tag 'scroll_right.png'), @next_group % end is there a best way to do this? am I on the right track?

  • jQTouch with PhoneGap on webOS

    - by Steve Nay
    I'm writing an application in PhoneGap that I want to run on iOS, Android, and webOS. jQTouch plays nice with everything on iOS and Android, but not webOS. Since the webOS Mojo framework is based on Prototype (which uses the $ variable), it's necessary to use jQuery in noConflict mode. I can handle that much. However, the problem is that I also want to use the jQTouch plugin. The jqtouch.js file uses $ throughout, causing JavaScript errors when that file is loaded. Is there a way to run the jQTouch plugin (or any plugin for that matter) in my PhoneGap application without interfering with Prototype?

Is there other preference ? the better way then the way i got now ?
