  • How can I load scripts, styles and images from a non-URL source?

    - by Jen
    I am integrating WebKit (via Qt) into an application. Instead of having WebKit retrieve scripts, CSS files and images via URLs, I want my application to provide them (e.g. retrieved from a database). For example, a "regular" web page may contain this tag: <IMG src="photos/album1/123456.jpg"> Instead of WebKit fetching this image from a server or the file system, I would prefer some kind of callback that allows my application to provide this image. How can I accomplish this?

  • HTTP request stream not readable outside of request handler

    - by Jason Young
    I'm writing a fairly complicated multi-node proxy, and at one point I need to handle an HTTP request, but read from that request outside of the "http.Server" callback (I need to read from the request data and line it up with a different response at a different time). The problem is, the stream is no longer readable. Below is some simple code to reproduce the issue. Is this normal, or a bug? function startServer() { http.Server(function (req, res) { req.pause(); checkRequestReadable(req); setTimeout(function() { checkRequestReadable(req); }, 1000); setTimeout(function() { res.end(); }, 1100); }).listen(1337); console.log('Server running on port 1337'); } function checkRequestReadable(req) { //The request is not readable here! console.log('Request writable? ' + req.readable); } startServer();

  • One-liner javascript to collect values from object graph?

    - by Kevin Pauli
    Given the following object graph: { "children": [ { "child": { "pets": [ { "pet": { "name": "fido" } }, { "pet": { "name": "fluffy" } } ] } }, { "child": { "pets": [ { "pet": { "name": "spike" } } ] } } ] } What would be a nice one-liner (or two) to collect the names of my grandchildren's pets? The result should be ["fido", "fluffy", "spike"] I don't want to write custom methods for this... I'm looking for something like the way jQuery works in selecting dom nodes, where you can just give it a CSS-like path and it collects them up for you. I would expect the expression path to look something like "children child pets pet name"

  • Silverlight 4 Multithread

    - by DavyMac23
    I'm trying to update my Silverlight 4 UI approx every 1/2 second with new data. I've hooked into a WCF service using net.tcp binding and issuing callbacks from the server. To make sure I get the data from the service as quickly as possible I've started up my proxy on a backround worker inside of my Silverlight App. My question is, how do I get the results from the callback and update the ObservableCollection that is bound to a datagird? I've tried a number of different ways and keep getting the dreaded cross-thread error.

  • set highchart margin

    - by user1392330
    I have built a a higcharts charts and I am displaying them one at a time on mouseover. The jquery creates a floting div (depending on the cursor) with a border line 1px solid black and then the highchart method is being called to draw the chart. The thing is that highcharts exceed and left and bottom border is not shown. I tired 'margin' : chart: { renderTo: 'graph', defaultSeriesType: 'line', zoomType: 'x', margin: [ 10, 10, 10, 10] }, and still it does the same thing.

  • Provide local fallback for CSS from CDN

    - by BadHorsie
    I'm loading the Bootstrap CSS on my page from the CDN bootstrapcdn.com <link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css" rel="stylesheet"> How can I test if the stylesheet was loaded, and if not provide a local fallback? I do not want to wait for jQuery or other libraries to load before doing the test; I want all CSS to be loaded on the page first.

  • Return popupmenu selection in MATLAB using one line of code

    - by Doresoom
    I have a GUI which uses a selection from a popupmenu in another callback. Is there a way to return the selected value of the popupmenu in only one line without creating any temporary variables? I've tried several solutions, but I've only managed two lines with one temporary variable: Three lines: list=get(handles.popupmenu1,'String'); val=get(handles.popupmenu1,'Value'); str=list{val}; Two lines: temp=get(handles.popupmenu1,{'String','Value'}); str=temp{1}{temp{2}}; Can anyone shave it down to one? PS, It's a dynamic menu, so I can't just use get(handles.popupmenu1,'Value') and ignore the string component altogether.)

  • Why is url not registered?(Drupal 6.x)

    - by Andrew
    I'm using hook_menu to register new url so that accessing this url would return some data to ajax function. As title suggested, this url is not registered. How do I know that? I've tried typing this in address bar but, drupal, return main template only rather than the tests string that I created. I'm positive that my module is working for php issues error if I intentionally write wrong syntax. And, yes, I clear cache whenever I make changes. Here's the code - function test_menu() { $my_form['test'] = array( 'title' => 'Test address', 'page callback' => 'test', 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, ); return $my_form; } function test(){ $a= "testing"; return $a; }

  • Improving Javascript Load Times - Concatenation vs Many + Cache

    - by El Yobo
    I'm wondering which of the following is going to result in better performance for a page which loads a large amount of javascript (jQuery + jQuery UI + various other javascript files). I have gone through most of the YSlow and Google Page Speed stuff, but am left wondering about a particular detail. A key thing for me here is that the site I'm working on is not on the public net; it's a business to business platform where almost all users are repeat visitors (and therefore with caches of the data, which is something that YSlow assumes will not be the case for a large number of visitors). First up, the standard approach recommended by tools such as YSlow is to concatenate it, compress it, and serve it up in a single file loaded at the end of your page. This approach sounds reasonably effective, but I think that a key part of the reasoning here is to improve performance for users without cached data. The system I currently have is something like this * All javascript files are compressed and loaded at the bottom of the page * All javascript files have far future cache expiration dates, so will remain (for most users) in the cache for a long time * Pages only load the javascript files that they require, rather than loading one monolithic file, most of which will not be required Now, my understanding is that, if the cache expiration date for a javascript file has not been reached, then the cached version is used immediately; there is no HTTP request sent at to the server at all. If this is correct, I would assume that having multiple tags is not causing any performance penalty, as I'm still not having any additional requests on most pages (recalling from above that almost all users have populated caches). In addition to this, not loading the JS means that the browser doesn't have to interpret or execute all this additional code which it isn't going to need; as a B2B application, most of our users are unfortunately stuck with IE6 and its painfully slow JS engine. Another benefit is that, when code changes, only the affected files need to be fetched again, rather than the whole set (granted, it would only need to be fetched once, so this is not so much of a benefit). I'm also looking at using LabJS to allow for parallel loading of the JS when it's not cached. So, what do people think is a better approach? In a similar vein, what do you think about a similar approach to CSS - is monolithic better?

  • Sharepoint connected web parts question

    - by philj
    I have one web part (the provider) which displays insurance claims in a gridview. When user clicks on one this value(case number) is passed via IWebPartField interface to another web part(consumer) which displays detailed info about the claim. So far so good. I can select different claims in the provider and the details show up in the consumer just fine. The moment I add a TextBox to the consumer, the consumer no longer recognizes the case number passed. I need the user to be able to enter a value in the textbox and click a button to update that claim info. I can debug and attach to process and it looks like it is getting the case in the callback function, etc, but when it is setting parameters for the stored proc in CreateChildControls, it is null. Comment out the TextBox and it works fine. Any clues as to what is going on? Brand new to Sharepoint web parts...any help appreciated! thanks, PhilJ

Also any effeciency improvements would be appreciated :)

  • freeGLUT keyboard input

    - by peaker
    I'm using GLUT (freeglut3) (via the Haskell GLUT bindings). import Graphics.UI.GLUT handleKBMouse :: KeyboardMouseCallback handleKBMouse key keyState mods mousePos = do print (key, keyState, mods, mousePos) main :: IO () main = do getArgsAndInitialize createWindow "testTitle" keyboardMouseCallback $= Just handleKBMouse mainLoop It seems that various important keys (e.g: Shift+Tab) do not call my callback. Also, "mods" doesn't describe the win-key, only Ctrl, Shift and Alt. Having such limited access to keyboard input is a serious impediment for real application development. Am I doing anything wrong here or is just freeglut just crippled? Is GLUT crippled in general?
