• Dojo treemodel- adding large number of items

  - by Ashley

  I am trying to add a large number of items (100+) to my tree via ForestStoreModel by calling newItem in a loop. This seems to be quite slow and locks up the browser. Is there any way I can do something similar to grid's beginUpdate & endUpdate? I want to basically 'turn off' my tree, add 100 items in a batch, then 'turn on' my tree. Any ideas? Thanks!

• Forcing Reload of View when returning from FlipSideView of Utility Application

  - by Chris McCall

  I've got a Utility Application for iPhone 3.1.3. I have my main view loading fine. I flip over to the flipside view of the utility app and change some settings. How can I call the code I've currently got in viewDidLoad in the main view to refresh it, as settings have changed? Do I create a public method and call it from the viewDidUnload method of the flipside view? Do I call viewDidLoad directly? What's the best way to do this?

• Force download through markup or JS

  - by mschoening

  Lets assume I have a file on a CDN (Cloud Files from Rackspace) and a static html page with a link to that file. Is there any way I can force download this file (to prevent it from opening in the browser -- for mp3s for example)? We could make our server read the file and set the corresponding header to: header("Content-Type: application/force-download") but we have about 5 million downloads per month so we would rather let the CDN take care of that. Any ideas?

• jQuery on() method not working for appended elements

  - by behz4d

  I know I should use on() method for triggering appended elements and not use click(), so: $('#change_profile_img').on('click', function(){ alert(1); }); so the above code is working fine on any elements unless the appended elements, for example, I'm appending: $('.companylogo:first').append('<a id="change_profile_img" class="ic_change">CHANGE IMAGE</a>'); after it's appended, it's not working, but after a page refresh it works just fine. Another thing that I should mention, I'm doing the append from a modal page, it appends the button and everything but I could not trigger it anymore... I would appreciate any kind of help. Thanks

• Is external JavaScript source available to scripting context inside HTML page?

  - by John K

  When an external JavaScript file is referenced, <script type="text/javascript" src="js/jquery-1.4.4.min.js"></script> is the JavaScript source (lines of code before interpretation) available from the DOM or window context in the current HTML page? I mean by using only standard JavaScript without any installed components or tools. I know tools like Firebug trace into external source but it's installed on the platform and likely has special ability outside the context of the browser sandbox.

• Do Silverlight APIs exist for diagramming?

  - by nw

  Do any Silverlight APIs exist to facilitate development of a custom browser-based diagramming app? It seems a shame to build something from scratch with shape primitives (such as this example), but I've searched Google and can't find much.

• How does SO's form remember previous input values?

  - by user198729

  I've noticed that the Title or Body part is remembered if I come back to the Ask Question page by pressing Back button of my browser. This feature is available in all browsers I tested, but doesn't exist for the forms in my own projects. How can I approach that effect? UPDATE I still don't have any clue yet,but guess it that some kind of client cache enabled by http headers or javascript?

• Is there an Javascript event for when a the page is pushed into the background?

  - by Georg

  I remember having used such an event, but I can't remember the name. The specific task I'm trying to accomplish is to stop my slideshow when the browser window isn't in the foreground. I'm fading the different images with jQuery, which uses quite some CPU power. Is there an event that tells me, when the user switches to another application / page.

• Why aren't Admob click callback delegate methods not getting called?

  - by executor21

  I'm integrating the latest version of the admob sdk (version 20100412) into my app. The ads get displayed, but I need the app to make some changes when an ad is clicked and admob displays a full-screen browser. However, none of the callback methods (willPresentFullScreenModal, didPresentFullScreenModal, willDismissFullScreenModal, and didDismissFullScreenModal) are called, even though other delegate methods are. Why aren't these callbacks being made? They were in the previous versions of the SDK, and the sample app doesn't use them, so it's no help.

• After 30 seconds, update MYSQL databse

  - by Sam

  Hello everyone! I've been looking around here on SO and Googling, however I can't find anything that fits my description. What I want to do is update the database if the page has not been refreshed after 30 seconds. I want to email a person with the contents of a form {submitted by a different user} (I can do that) IF the person has NOT visited the page (I can do that) within the last 30 seconds. What I've tried to do is make the page that should be visited refresh every 30 seconds, and so I figured if I did something like after 31 seconds, edit the database (so if the refreshed page was not refreshed, the database editing would run). I'm sorry if this sounds complicated, there's probably a better way to do this, but I'm not sure how. The bigger picture is I'm trying to make a 'on-duty' sort of thing, so that if the person is not actively looking at the page, they will get emailed with whatever the contents of the form is. The page will contain a table of all the entered form results.

• Small questions on data structure

  - by John Graveston

  Hi, I'm trying to search the parent of a node with Kruskal's algorithm. My program works just fine, but I think I have heard of a method to improve the speed of the algorithm by reconstructing the tree while searching for the parent node and connecting it to the parent node. I'm pretty sure that I've heard of this somewhere, maybe in a lecture. Can anyone refresh my memory? And also, given a number of arrays, when searching for the minimum and the maximum value from a certain section of an array, what is the name of the tree that can calculate the minimum/maximum value from the array by making a binary tree that has the minimum/maximum value of each array in O(log N)?

• Onclick not added until after Postback

  - by Morph

  I have the following: <asp:Button id="SubmitButton" Text="Submit" runat="server" OnClientClick="Do();" OnClick="SubmitButton_Click"/> When the page is first rendered, I go to the view source in my browser and see that the onclick="Do();" is not added to my submit button tag. But when I do a post back, and do the view source again, the onclick is added to the submit. Why would the onclick not be there on the first request?

• Few files out of sync but GIT doesn't seem to notice.

  - by doublejosh

  I have two repos that claim to be clean. One was originally cloned from the other and is used for dev work. There are a few files that I can see are not the same. However when I try pulling either way it says everything is up to date. How is this possible? Did that file miss a commit somehow? ...but shouldn't the difference be noticed regardless? Do I need a refresh of some sort?
