  • COMET with [Session ] TimeOut

    - by Amitd
    hi guys, Just Wondering how [Session] timeouts are(or can be) implemented when using Comet? I'm using Long polling Comet solution and want to implement a kind of Timeout feature. Example : If the user is on a Comet enabled page and doesn't respond to server events/notification for a period of time say 10 mins then invalidate his session and remove his request from server and redirect the user to a timeout page? Will this require Javascript XHR requests to check for a timeout explictly? Using ASP.NET 3.5 / C# (Doesn't need to be language specific) Thanks

  • |Ideas for applications using face detection and recognition

    - by Omry
    Full disclosure: I work at face.com. Face.com just launched a free (up to an hourly limit) face detection and recognition REST API. We got a very handy API sandbox that developers can use to play the API and to see what it can and can't do. Besides the obvious point of letting you guys know about the API, I wanted to hear from you what kind of applications you think can be developed with it. Some pretty obvious ideas: Face based login (not entirely secure but still fun). Automatic face crop for sites that let users upload photos (dating sites etc) Some kind of integration into augmented reality games There is no right or wrong answers here, use your imagination :).

    - by Jeff Dias
    So, I am working in this page http://universidadedoingles.com.br/text-tabs/tabs-text.html As you guys can see, I have four tabs and an arrow right below, I need to do that the arrow go below the selected tab, if a click on tab 3, that arrow should go below tab 3, simple as that! but I don`t know! You also can see that when the page loads on tab 1 and you click on tab 2 the effect I want works pretty well, here`s the jquery I am using for that: $(document).ready(function() { $("a.tab2").click(function() { $(".arrow-spacer").addClass("tabs2"); }); }); That`s it, thank you vey much for any kind of help. p.S - i am using a mac, so theres no IE for testing yet, this looks good in Safari and Chrome.

  • Flash ActionScript 2.0 problem with the object's _visible parameter

    - by GMan
    Hey guys, I've been trying to build something simple in Flash 8, and I stumbled across something weird I cannot explain: I have an object, and at some point of the program, I want it to be visible (it is invisible at first), so I write: _root.myObj._visible = true; _root.gameOver.swapDepths(_root.getNextHighestDepth()); //so it will be on the top and this works fine, the object becomes visible and etc. What I planned to happen next is that the user presses a button on that same object, and the object will go invisible: on(release) { trace(_root.myObj._visible); _root.myObj._visible = false; trace(_root.myObj._visible); _root.gotoAndPlay("three"); } The trace returns at first true and later on false, so the command works, but oddly the object stays visible, that's what I don't understand. Thanks everybody in advance.

  • WPF binding and pointers

    - by Eran
    hey guys, I have a WPF application that contains windows with few user controls and Coordinator object. the window and all its user controls pointing to an object, which instace is in the Coordinator, by thier DataContext. the problem is that I want to change this object (e.g. create new object()) in the Coordinator but I want all the dataContexts to point to the new object. I tried to send the object by ref to the window constructor but it didn't help. any idea about how can I rewrite the memory location that all pointers are pointing to? (I don't want to repalce the properties in object since its a lot of work nor to use a middle object that points to the replaced object) Thanks Eran

  • Why is the JVM stack-based and the DalvikVM register based?

    - by aioobe
    I'm curious, why did Sun decide to make the JVM stack-based and Google decide to make the DalvikVM register based? I suppose the JVM can't really assume that a certain number of registers are available on the target platform, since it is supposed to be platform independent. Therefor it just postpones the register-allocation etc, to the JIT compiler. (Correct me if I'm wrong.) So the Android guys thought, "hey, that's inefficient, let's go for a register based vm right away..."? But wait, there are multiple different android devices, what number of registers did the Dalvik target? Are the Dalvik opcodes hardcoded for a certain number of registers? Do all current Android devices on the market have about the same number of registers? Or, is there a register re-allocation performed during dex-loading? How does all this fit together?

  • Learning Visual C++ 2008 and C++ at the same time? Any resources to recommend?

    - by Javed Ahamed
    Hey guys, I am trying to learn Visual C++ 2008 and C++ at the same time to get involved with sourcemod, a server side modding tool for valve games. However I have never touched Visual C++ or C++ in general, and doing some preliminary research I am quite confused on these different versions of C++ (mfc, cli, win32), and why a lot of people seem to hate Visual C++ and use something like Borland instead. I really learn visually, and have used videos from places like Lynda.com with great success. I was wondering if anyone had any exceptional resources they had come across to teach Visual C++ 2k8, with its intricacies and setting up the IDE along with C++ at the same time. Books would be nice, but videos would be preferred, and I don't mind paying for resources. Thanks in advance!

  • How to change to a grouped table view in xcode without using Interface Builder

    - by Dave
    I have a table that I created within xcode so there is no nib file in this case. I want to make my table into the 'Grouped' style but im not sure how. I think it has somthing to do with the method below, the problem is Im not really sure how to call it, I do understand how methods work I'm just not too sure on where to start with this one: - (id)initWithFrame:(CGRect)frame style:(UITableViewStyle)UITableViewStyleGrouped So could someone tell me how to call it? The problem is that its not a method I wrote its a built in one so I could put that line into my header file but how would I use it in my implementation file? Thanks guys,

  • Pass Data to Data Template Selector

    - by Michael Sync
    How do you guys pass the data (parameter) to DataTemplate Selector? The only one that I can think of is to use an attached property in DataTemplate Selector? Example: public class DisableWeekendsSelection : DataTemplateSelector { [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2211:NonConstantFieldsShouldNotBeVisible", Justification = "DependencyProperty")] public static readonly DependencyProperty Parameter = DependencyProperty.RegisterAttached("Parameter", typeof(ObservableCollection<Date>), typeof(DisableWeekendsSelection), new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault)); public static ObservableCollection<Date> GetParameter(DependencyObject dp) { return dp.GetValue(Parameter) as ObservableCollection<Date>; } public static void SetParameter(DependencyObject dp, ObservableCollection<Date> value) { dp.SetValue(Parameter, value); } public override DataTemplate SelectTemplate(object item, DependencyObject container) { The problem with this approach is that I'm not able to get the value of Parameter in SelectTemplate method. Any suggestion would be appreciated. Thanks in advance.

  • Core Plot on iPad Runs with Debugger, not Standalone

    - by phantomdata
    Hey guys, Thanks to Ole Begemann, I spent yesterday digging around in Core Plot to explore adding graphing to an iPad application that I've been working on. I was fairly satisfied with it, and wanted to show it off to a friend of mine - so I stopped the debugger, took the device off the dock, handed it over to my friend and pushed the icon. Lo, it started and then immediately crashed. I figured that it was using the release profile, and on a whim went ahead and compiled and ran (through the debugger) under the release profile instead of the debug. As expected, it crashed right away with EXC_BAD_ACCESS. I have added the relative path to the core plot to Release configuration and -all_load and -ObjC to the "other" linker flags - just like in the debugger profile and googled all around. IT seems that most people with this issue have forgotten to add the linker flags. Does anyone have any suggestions for next steps in figuring out this issue?

  • Jquery.form plugin and jquery.validation and it's submitHandler not working correctly... please help

    - by Matthew
    Hello guys, I was hoping someone can shed some light on what might be occurring on my page. Okay what I currently have on my page is a simple form that collects first name, last name, city, state and email. Once submitted it will hit a PHP page that updates our DB and echo's back to the designted div with a class of .response. I am using jquery.validation and placing that dynamic function within the submitHandler like so: submitHandler: function(form) { $(form).ajaxSubmit({ target: '.response', // target element(s) to be updated with server response resetForm: true, success: function() { $('#commentform').hide(); $('.response').show(); } }); So what I am getting is a div that is not being populated with the echo from my php file in FF and in IE I am getting the message of thank you but the page is taking me to the update.php script in which I have the form action pointing to. I am not sure what I am missing... Thanks, Matt

  • Random blank pages on Safari when developing webapp

    - by Ali
    Hey guys, I've been experiencing a safari problem while building a web application. The screen goes completely blank (white) and refreshing won't help. Going to another page on the site gives the same problem. Then magically, after a little while, everything goes back to normal and pages are rendered correctly! This started happening around the same time that I SUSPECT my hosting automatically upgraded from PHP 5.2.x to 5.3 (all of a sudden, we got 'deprecated function' errors and the error settings and handling were unchanged) I also have to mention that this doesn't happen in our dev environment (PHP 5.2.9, Apache 2) Settings Safari 4.0.2 and the latest one (don't know the version) Server side: PHP 5.3, MySQL 5.0.90, Apache is cPanel Easy Apache v3.2.0 Does anyone know why this is happening at all, or how to fix it? I appreciate any help or pointers you might have. Thanks!

  • Rails Plugin - Install as Plugin or Install As Gem

    - by Joseph Misiti
    Hey guys, I am new to rails and have a question regarding the plugins. It seems there are two approaches you can take when using a third party plugin in a ROR App: 1) install a gem using sudo gem install GEM, and then "require" it in your rails project 2) install the plugin using script/generate plugin install PLUGIN. The plugin in code appears in your vendor directory and then you are good to go (sometimes, i could not get Devise working via this method). Since it appears both of these methods accomplish them same thing, why should I choose one method over the other. Thanks,

  • Dot Net Nuke - Sub Domains

    - by Tristan
    Hi Guys, I've got a DNN portal set up for me and my brother, which works, and i'd like to make it so that sub domains point to our respective sub section of the sites. I.e. brothers.co.uk = brothers.co.uk/home.aspx me.brothers.co.uk = brothers.co.uk/me.aspx him.brothers.co.uk = brothers.co.uk/him.aspx I've got the sub sections set up in DNN, but can't figure out what to do with domain names to get it working. I'd like this to be all one site with the same login set, although if there's a better way to structure this, I'm open to ideas. Any thoughts? Regards Tristan

  • Entity Framework - Using a list as a paramater in a compiled query

    - by vdh_ant
    Hi guys Just wondering if anyone knows whether I should be able to pass in list into a compiled query and have the query perform a contains operation? The reason why I ask is that I have a scenario where I need to do this, yet at run time I am getting the following error... The specified parameter 'categories' of type 'System.Collections.Generic.List`1[[System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' is not valid. Only scalar parameters (such as Int32, Decimal, and Guid) are supported. I can understand why this might be the case but I was wondering if anyone knows a way around it. Cheers Anthony

  • TinyMCE editor dislikes being moved around

    - by zneak
    Hello guys, On a page I have, I need to move TinyMCE editors in the DOM tree once in a while. However, for some reason, the editor doesn't like it: it clears itself completely and becomes unusable. As far as I can see, this behavior is consistent between Safari 4 and Firefox 3.6, but not Internet Explorer 7/8. Here's an example. It truly is pissing me off to do something that works in Internet Explorer but not with more appreciable browsers. Is there something I missed in the docs about never trying to move an editor in the DOM tree? Is there some kind of workaround?

  • C# SqlBulkCopy and Data Entities

    - by KP
    Guys, My current project consists of 3 standard layers: data, business, and presentation. I would like to use data entities for all my data access needs. Part of the functionality of the app will that it will need to copy all data within a flat file into a database. The file is not so big so I can use SqlBulkCopy. I have found several articles regarding the usage of SqlBulkCopy class in .NET. However, all the articles are using DataTables to move data back and forth. Is there a way to use data entities along with SqlBulkCopy or will I have to use DataTables?

I have followed a steps regarding on compiling VS Solution/Project for 64bit. But when I start to to compile the solution for 64bit, this "Crownwood.Magic.Forms" (MagicLibrary.dll) doesn't work anymore.

  • doctrine regenerating models from yml only the base models?

    - by TaMeR
    I am wondering if there is a way to handle this more elegantly. After generating the "main" models and base models from yml files the first time I have to add at the very leased an include for the base model to the "main" model like so: include_once 'generated/BaseBlog.php'; At the moment before I regenerate the models I move my changed main models, which is mostly way more then just the include path, in to a tmp folder then I delete all the models. And after regenerating I move my modified models back overwriting the generated main models. isn't there a way to just create the base models and not touch the main models? Or how do you guys handle this?

  • Database Network Latency

    - by Karl
    Hi All, I am currently working on an n-tier system and battling some database performance issues. One area we have been investigating is the latency between the database server and the application server. In our test environment the average ping times between the two boxes is in the region of 0.2ms however on the clients site its more in the region of 8.2 ms. Is that somthing we should be worried about? For your average system what do you guys consider a resonable latency and how would you go about testing/measuring the latency? Karl
