  • Textbox autofill not in correct position in safari

    - by jerjer
    Hello All, Has anyone experience this weird issue on safari? Textbox autofill is not at its correct position, please see screenshot below. I have been searching for answers in google for almost a day, still no luck. This is the built-in autofill feature of safari. Here is the markup: index.php <html> <body> <div id="nav"></div> <div id="content"> <iframe style="width:100%;height:100%" src="add_user.php" frameborder="0"></iframe> </div> .... </body> </html> add_user.php <html> .... <body> <form method="post"> <h3>Add User (Admin only) <div id="msg">Please enter First and Last Name.</div> <ul> <li><label>* Email</label> <input type="text" id="email" /></li> <li><label>* First Name</label> <input type="text" id="fname" /></li> <li><label>* Last Name</label> <input type="text" id="lname" /></li> .... </ul> </form> </body> </html> I am suspecting that this is caused by the iframe, but it works just fine in other browsers. Also I could not change the page design(using iframe) right away for practical reasons. Thanks

  • Easy way to observe user activity - how improve my database structure.

    - by Thomas
    Welcome, I need some advise to improve perfomence my web application. In the begin I had this structure of database: USER -id (Primary Key) -name -password -email .... PROFILE -user Primary Key, Foreign Key (USER) -birthday -region -photoFile ... PAGES -id (Primary Key) -user Foreign Key(USER) -page -date COMMENTS -id (Primary Key) -user Foreign Key(USER) -page Foreign Key(PAGE) -comment -date FAVOURITES_PAGES -id (Primary Key) -user Foreign Key(USER) -favourite_page Foreign Key(PAGE) -date but now one of the most important page of website is observatory, when everyone can observe activity others users. So I need select all pages, comments and favourites pages some users and display it in one list, sorted by date. For better perfomance (I think) I changed my structure to this: table USER and PROFILE without changes ACTIVITY (additional table- have common fields: user,date) -id (Primary Key) -user Foreign Key(USER) -date -page Foreign Key(PAGE) -comment Foreign Key(COMMENTS) -favourite_page Foreign Key(FAVOURITES_PAGES) PAGES -id (Primary Key) -page COMMENTS -id (Primary Key) -page Foreign Key(PAGE) -comment FAVOURITES_PAGES -id (Primary Key) -favourite_page Foreign Key(PAGE) So now it is very easy get sorted records from all tables. But I have no only foreign key to PAGES, COMMENTS and FAVOURITES_PAGES in ACTIVITY table - there is about ten Foreign Key fields and in one record only one have value, others have None: ACTIVITY id user date page comment ... 1 2 2010-02-23 None 1 2 1 2010-02-21 1 None .... It is corect solution. When I display about 40 records in one page (pagination) I must wait about one secound, but database is almost emty (a few users and about 100 records in others tables). It is depends on amount records per page - I have checked it, but why it takes too long time, becouse of relationships? The website is built in Python/Django. Any advices/opinion?

  • Coherent access to mainframe files from Win32 application and IBM RDZ/Eclipse?

    - by Ira Baxter
    I have a suite of tools for processing IBM COBOL source code; these tools are built as Win32 applications and talk to Windows (including network) files using traditional Windows file system calls (open, close, read, write) and work just fine, thank you. I'd like to integrate these with Eclipse; we understand how to get Eclipse to do UI for us we think. The problem is that Eclipse/RDZ users access mainframe files through some IBM magic. In How does RDZ access mainframe files I tried to understand how Eclipse accessed files on a mainframe. Apparantly Eclipse/RDZ has a secret filesystem access backdoor not available to normal mortals. At issue is how our tools, reading some Windows-accessible file (local disk file, NFS to mainframe, ...) can associate such files with the files that Eclipse can access or is using? Ideally we'd like UI-integrated versions of our tools take an Eclipse file-name string for a mainframe file, pass it to our Windows application to process, have the Windows application open/read/process the file, and return results associated with that file to the Eclipse UI. Is there a canonical file name path that would be used with mainframe NFS that would be equivalent to the name or access object the Eclipse RDZ used to access the same file? Are all operations doable internally by Eclipse, doable by the mainframe NFS [for instance, can NFS read/update an element in a partitioned data set? Can Eclipse RDZ? Does it matter?] Is the mainframe file access available to custom Java code running under Eclipse RDZ (e.g., equivalents of open/close/read/write based on filename/path/something?) If so, can somebody steer me towards documentation describing the access methods? Anybody else already solve this problem or have a good suggestion?

  • rails search nested set (categories and sub categories)

    - by bob
    Hello, I am using the http://github.com/collectiveidea/awesome_nested_set awesome nested set plugin and currently, if I choose a sub category as my category_id for an item, I can not search by its parent. Category.parent Category.Child I choose Category.child as the category that my item is in. So now my item has category_id of 4 stored in it. If I go to a page in my rails application, lets say teh Category page and I am on the Category.parent's page, I want to show products that have category_id's of all the descendants as well. So ideally i want to have a find method that can take into account the descendants. You can get the descendants of a root by calling root.descendants (a built in plugin method). How would I go about making it so I can query a find that gets the descendants of a root instead of what its doing now which is binging up nothing unless the product had a specific category_id of the Category.parent. I hope I am being clear here. I either need to figure out a way to create a find method or named_scope that can query and return an array of objects that have id's corresponding tot he descendants of a root OR if I have any other options, what are they? I thought about creating a field in my products table like parent_id which can keep track of the parent so i can then create two named scopes one finding the parent stuff and one finding the child stuff and chaining them. I know I can create a named scope for each child and chain them together for multiple children but this seems a very tedious process and also, if you add more children, you would need to specify more named scopes.

  • asp.net mvc client side validation; manually calling validation via javascript for ajax posts

    - by Jopache
    Under the built in client side validation (Microsoft mvc validation in mvc 2) using data annotations, when you try to submit a form and the fields are invalid, you will get the red validation summary next to the fields and the form will not post. However, I am using jquery form plugin to intercept the submit action on that form and doing the post via ajax. This is causing it to ignore validation; the red text shows up; but the form posts anyways. Is there an easy way to manually call the validation via javascript when I'm submitting the form? I am still kind of a javascript n00b. I tried googling it with no results and looking through the js source code makes my head hurt trying to figure it out. Or would you all recommend that I look in to some other validation framework? I liked the idea of jquery validate; but would like to define my validation requirements only in my viewmodel. Any experiences with xval or anything of the sort?

  • Best Practices for Setup and Management of an Open Source Project

    - by VirtuosiMedia
    Later this year I want to release a PHP framework that I've been working on as open source. I do use source control (SVN), but it's on an extremely limited basis. I'm self-taught, I develop by myself and don't have the experience of working with large teams. I have some ideas about what can help make a project successful, but I'm fuzzy on some of the details. Since it's not yet released, I want to do everything I can to set up the right infrastructure from the beginning. What do I need to know in order to setup and manage a successful project? Some ideas that I have to make it successful (beyond marketing it): Good documentation and tutorials Automated unit tests and builds to push update to the website A clear roadmap Bug Tracking integrated with the source control A style guide to keep the code consistent along with clear A forum for the community to get support, share ideas, etc. A good example application built with the framework A blog to keep the community informed Maintaining backwards compatibility wherever possible Some of my questions: How do I setup and automate a one step submit-test-commit-generate API docs-push update to website process? How do I handle (technically) submissions from other users? How can I ensure that those submissions must be approved before being integrated? What are some of the pitfalls that can be avoided in terms of the project community? I'd prefer to have it be as friendly and helpful as possible without a lot of drama. I'd love to learn from your experience on any of these points. If you think I'm missing anything big, please share that as well. Any resources (preferably geared toward a beginner) that you could point me towards would also be greatly appreciated.

  • What's the expectation for silverlight 2's lifespan?

    - by dwidel
    Way back when I built an internal site for a customer using silverlight 2. They've been happy with it and I've barely had to touch it. Is the expectation that this site will always work? What I'm afraid of is suddenly getting a call years from now that the users installed silverlight X and now it's broken and I'm going to have to convert it immediately past Y versions of Silverlight to get the site back up, and I don't even do Silverlight anymore. I already went through this once when it went from 2 beta to 2 release and and scrambling to fix all the breaking changes and get the site back up. It wasn't as big a deal then as we were in beta anyway. I could upgrade now but it would be really tough to go back to the customer and ask for money to do an upgrade when they are happy now and will see no noticeable benefit from staying current. Additionally there are some third party controls that would have to be licensed again. So I guess what I'm asking is there a known end of life? Or do we just play it by ear?

  • Custom Membership in ASP.NET MVC 2

    - by Interfector
    Hello, I'm trying to make my Custom Membership starting from ASP.NET's. I have a users table created by me which has as Primary Key a Guid UserId, exactly the sames as ASP.NET's default user and membership table. I have all the Foreign Key relationships built. However, I cannot insert the user into my custom users table. The data gets inserted correctly into the default ASP.NET's tables. I have tried the following scenarios: First version Receive the user model from POST call the CreateUser method of the Membership.class (stuff gets inserted) without modifying the user object, I try to insert it using EF's AddObject I receive the following error: "Cannot insert the value NULL into column 'LoweredUserName', table 'asp.dbo.aspnet_Users'; column does not allow nulls. INSERT fails.\r\nThe statement has been terminated."} System.Exception {System.Data.SqlClient.SqlException The error actually makes sense as EF's AddObject doesn't know how to create the LoweredUserName value, and I don't want to do it, this is ASP.NET's job. Second version Receive the user model from POST call the CreateUser method of the Membership.class (stuff gets inserted) Get the Guid of the freshly inserted system user get the ASP.NET's User object and overwrite that of user.User get the ASP.NET's Membership object and overwrite that of user.Membership (remember the FKs) try again EF's AddObject new error {"The relationship between the two objects cannot be defined because they are attached to different ObjectContext objects."} System.Exception {System.InvalidOperationException} Don't know what this is, but it certenly doesn't make any sense for me. After some googleing I think that it has something to do with the context, but as I'm a beginner I don't know how to fix it. Any ideeas on how to accomplish this task are more than welcomed, especially if they follow some good practices. Thx

  • Can I trigger PHP garbage collection to happen automatically if I have circular references?

    - by Beau Simensen
    I seem to recall a way to setup the __destruct for a class in such a way that it would ensure that circular references would be cleaned up as soon as the outside object falls out of scope. However, the simple test I built seems to indicate that this is not behaving as I had expected/hoped. Is there a way to setup my classes in such a way that PHP would clean them up correctly when the outermost object falls out of scope? I am not looking for alternate ways to write this code, I am looking for whether or not this can be done, and if so, how? I generally try to avoid these types of circular references where possible. class Bar { private $foo; public function __construct($foo) { $this->foo = $foo; } public function __destruct() { print "[destroying bar]\n"; unset($this->foo); } } class Foo { private $bar; public function __construct() { $this->bar = new Bar($this); } public function __destruct() { print "[destroying foo]\n"; unset($this->bar); } } function testGarbageCollection() { $foo = new Foo(); } for ( $i = 0; $i < 25; $i++ ) { echo memory_get_usage() . "\n"; testGarbageCollection(); } The output looks like this: 60440 61504 62036 62564 63092 63620 [ destroying foo ] [ destroying bar ] [ destroying foo ] [ destroying bar ] [ destroying foo ] [ destroying bar ] [ destroying foo ] [ destroying bar ] [ destroying foo ] [ destroying bar ] What I had hoped for: 60440 [ destorying foo ] [ destorying bar ] 60440 [ destorying foo ] [ destorying bar ] 60440 [ destorying foo ] [ destorying bar ] 60440 [ destorying foo ] [ destorying bar ] 60440 [ destorying foo ] [ destorying bar ] 60440 [ destorying foo ] [ destorying bar ]

  • What's are the best readings to start using WPF instead of WinForms?

    - by Ivan
    Keeping in mind what CannibalSmith once said - "All the answers are saying "WPF is different". That's a huge understatement. You not only have to learn lots of new stuff - you must forget everything you've learned from Forms. It's a completely new way of doing UI." .. and having many years of experience with visual Windows desktop applications development (VB6, Borland C++ Builder VCL, WinForms) (which is hard to forget), how do I quickly move to developing to say well-formed WPF applications with Visual Studio? I don't need boozy-woozy graphics to give my app look and feel of a Hollywood blockbuster or a million dollar pyjamas. I always loved tidiness of standard Windows common controls and UI design guidelines, end even more I enjoyed them under Vista Glass Aero Graphite sauce. I am perfectly satisfied with WinForms but I want to my applications to be built of the most efficient and up-to-date standard technologies and architectured according to the most efficient and flexible patterns of today and tomorrow, leveraging interface-based integration and functionality reuse and to take all advantages of modern hardware and APIs to maximize performance, usability, reliability, maintainability, extensibility, etc. I very much like the idea of separating view, logic and data, letting a view to take all advantages of the platform (may it run as a web browser applet on a thin client or as a desktop application on a PC with a latest GPU), letting logic be reused, parallelized and seamlessly evolve, storing data in a well structured format in a right place. But... while moving from VB6 to Borland C++ Builder was very easy (no books/tutorials needed to turn it on and start working) (assuming I already knew C++), moving from BCB to WinForms was the same seamless, it does not seem any obvious to me how to do with WPF. So how do I best convert myself from a WinForms developer into a right-way thinking and doing WPF developer?

  • Using R in Processing through rJava/JRI?

    - by tommy-o-dell
    Hi guys, Is it possible to run R in Processing through rJava/JRI? If I deployed a Processing app on the web, would the client need R on their system? I'm looking to create an interactive information dashboard that I can deploy on the web. It seems that Processing is probably my best bet for the interactive/web part of things. Unfortunately, it doesn't look like there are many math/stats functions built-in. And there aren't any libraries for plotting data either. I've been using R and gpplot2 for a few months and am thrilled (amazed) at how easily it manipulates and plots data. So I'm wondering now if can get the best of both worlds and run R through a Processing applet. From the JRI website: JRI is a Java/R Interface, which allows to run R inside Java applications as a single thread. Basically it loads R dynamic library into Java and provides a Java API to R functionality. It supports both simple calls to R functions and a full running REPL. In a sense JRI is the inverse of rJava and both can be combined (i.e. you can run R code inside JRI that calls back to the JVM via rJava). The JGR project makes the full use of both JRI and rJava to provide a full Java GUI for R. JRI uses native code, but it supports all platforms where Sun's Java (or compatible) is available, including Windows, Mac OS X, Sun and Linux (both 32-bit and 64-bit). Thanks for the advice :)

  • Percent-Encoded Percent in URI

    - by Lukas
    In our application, it is possible for a user to upload files then download them later. We don't restrict them from having any special characters in the file name. The problem comes in when we create the link for the user to download the file. I use the Java URL encoder to encode the file name that gets put into the href of the link, but I'm still having problems with percent (%) signs. For example, if the user uploads a file named fi%le.jpg, the href that gets generated is fi%25le.jpg, and everything is fine. The problem is when the percent sign is right before the period (i.e., file%.jpg, which gets converted to file%25.jpg). When the user clicks on the link, they get a 404 (Not Found) error. The strange thing is that it is not a problem if the two characters following the percent sign are hex characters.... Weird, eh? Any help is appreciated. I am using Tomcat/Struts. Could the built-in URL decoder have anything to do with this problem?

  • Post a form from asp to asp.Net

    - by Atomiton
    I have a classic asp application. I want to post a contest form from that page to an Asp.Net form. The reason is that I want to use a lot of logic i have built into an Asp.Net page for validation before entering into the database and I don't know asp very well. Not to mention asp.Net being more secure. What's the best way to accomplish this goal? My thoughts are as follows: My asp Page: <html> <body> <form action="/Contests/entry.aspx" method="post"> Name: <input type="text" name="fname" size="20" /> Last Name: <input type="text" name="lname" size="20" /> <input type="submit" value="Submit" /> </form> </body> </html> aspx page is running in a Virtual Directory and would handle anything posted to it. Is this possible, or does aspx prevent this kind of thing? I ( preferably ) don't want to create the form in aspx as my colleague wants to have control of the page and build the html himself and I don't want the hassle of constantly changing it. Are there caveats I need to consider? What roadblocks will I run into? How do I access the Posted Form Values? Request.Form?

  • Vote on Pros and Cons of Java HTML to XML cleaners

    - by George Bailey
    I am looking to allow HTML emails (and other HTML uploads) without letting in scripts and stuff. I plan to have a white list of safe tags and attributes as well as a whitelist of CSS tags and value regexes (to prevent automatic return receipt). I asked a question: Parse a badly formatted XML document (like an HTML file) I found there are many many ways to do this. Some systems have built in sanitizers (which I don't care so much about). This page is a very nice listing page but I get kinda lost http://java-source.net/open-source/html-parsers It is very important that the parsers never throw an exception. There should always be best guess results to the parse/clean. It is also very important that the result is valid XML that can be traversed in Java. I posted some product information and said Community Wiki. Please post any other product suggestions you like and say Community Wiki so they can be voted on. Also any comments or wiki edits on what part of a certain product is better and what is not would be greatly appreciated. (for example,, speed vs accuracy..) It seems that we will go with either jsoup (seems more active and up to date) or TagSoup (compatible with JDK4 and been around awhile). A +1 for any of these products would be if they could convert all style sheets into inline style on the elements.

  • xsd.exe - schema to class - for use with WCF

    - by NealWalters
    I have created a schema as an agreed upon interface between our company and an external company. I am now creating a WCF C# web service to handle the interface. I ran the XSD utility and it created a C# class. The schema was built in BizTalk, and references other schemas, so all-in-all there are over 15 classes being generated. I put [DataContract} attribute in front of each of the classes. Do I have to put the [DataMember] attribute on every single property? When I generate a test client program, the proxy does not have any code for any of these 15 classes. We used to use this technique when using .asmx services, but not sure if it will work the same with WCF. If we change the schema, we would want to regenerate the WCF class, and then we would haev to each time redecorate it with all the [DataMember] attributes? Is there an newer tool similar to XSD.exe that will work better with WCF? Thanks, Neal Walters SOLUTION (buried in one of Saunders answer/comments): Add the XmlSerializerFormat to the Interface definition: [OperationContract] [XmlSerializerFormat] // ADD THIS LINE Transaction SubmitTransaction(Transaction transactionIn); Two notes: 1) After I did this, I saw a lot more .xsds in the my proxy (Service Reference) test client program, but I didn't see the new classes in my intellisense. 2) For some reason, until I did a build on the project, I didn't get all the classes in the intellisense (not sure why).

  • Error displaying a WinForm in Design mode with a custom control on it.

    I have a UserControl that is part of a Class library. I reference this project from my solution. This adds a control from the referenced project to my toolbox. I add tghe control to a form. Everything looks good, I compile all and run. Perfect... But when I close the .frm with the control on it and re-open it, I get this error. The code continues to run.

  • java.lang.ClassNotFoundException

    Hey everyone, I have a java project that I'm working on which was working until a few days ago. I'm not sure what I did to my Eclipse set-up to hose it but now I'm getting a java.lang.ClassNotFoundException when I try to run some code that accesses the google finance api.

  • inbound/outbound url routing in asp.net MVC

    - by Stephane
    The routing I need is quite simple, I must be missing something there. As code example I put the simpler situation where I can reproduce my behavior. You have this ActionMethod : public ActionResult Index(string provider) { ViewData["Message"] = provider; return View("Index"); } And you have this route : routes.MapRoute( null, "{controller}/{action}/{provider}", new { controller = "Home", action = "Index", provider = "Default" } ); // Parameter defaults You can call /Home/Index/Custom and provider will take the value "Custom" What Route would I need if I want the url /?provider=Custom to map the provider to the parameter. I thought that would just work, because the default controller and the default action would be used, and the provider from the querystring would be used instead of the default one. but the querystring is just ignored here. That's a problem in my situation as I have a form using HTTP GET method. The form action has to be Html.BeginForm(c=c.Index(null)) which is resolved as / and the value of my form are added in the querystring. (the provider being a dropdown in the form) So the url built by the form is /?abc=value&cde=value...

  • Perl, module export symbol

    - by Mike
    I'm having trouble understanding how to export a package symbol to a namespace. I've followed the documentation almost identically, but it seems to not know about any of the exporting symbols. mod.pm #!/usr/bin/perl package mod; use strict; use warnings; require Exporter; @ISA = qw(Exporter); @EXPORT=qw($a); our $a=(1); 1; test.pl $ cat test.pl #!/usr/bin/perl use mod; print($a); This is the result of running it $ ./test.pl Global symbol "@ISA" requires explicit package name at mod.pm line 10. Global symbol "@EXPORT" requires explicit package name at mod.pm line 11. Compilation failed in require at ./test.pl line 3. BEGIN failed--compilation aborted at ./test.pl line 3. $ perl -version This is perl, v5.8.4 built for sun4-solaris-64int

  • How does 'lazy' work?

    - by Matt Fenwick
    What is the difference between these two functions? I see that lazy is intended to be lazy, but I don't understand how that is accomplished. -- | Identity function. id :: a -> a id x = x -- | The call '(lazy e)' means the same as 'e', but 'lazy' has a -- magical strictness property: it is lazy in its first argument, -- even though its semantics is strict. lazy :: a -> a lazy x = x -- Implementation note: its strictness and unfolding are over-ridden -- by the definition in MkId.lhs; in both cases to nothing at all. -- That way, 'lazy' does not get inlined, and the strictness analyser -- sees it as lazy. Then the worker/wrapper phase inlines it. -- Result: happiness Tracking down the note in MkId.lhs (hopefully this is the right note and version, sorry if it's not): Note [lazyId magic] ~~~~~~~~~~~~~~~~~~~ lazy :: forall a?. a? -> a? (i.e. works for unboxed types too) Used to lazify pseq: pseq a b = a `seq` lazy b Also, no strictness: by being a built-in Id, all the info about lazyId comes from here, not from GHC.Base.hi. This is important, because the strictness analyser will spot it as strict! Also no unfolding in lazyId: it gets "inlined" by a HACK in CorePrep. It's very important to do this inlining after unfoldings are exposed in the interface file. Otherwise, the unfolding for (say) pseq in the interface file will not mention 'lazy', so if we inline 'pseq' we'll totally miss the very thing that 'lazy' was there for in the first place. See Trac #3259 for a real world example. lazyId is defined in GHC.Base, so we don't have to inline it. If it appears un-applied, we'll end up just calling it. I don't understand that because it refers to lazyId instead of lazy. How does lazy work?

  • Why won't .attr('checked','checked') set?

    - by Jason
    I have the following snippet of code (I'm using jQuery 1.4.2): $.post('/Ads/GetAdStatsRow/', { 'ad_id': id }, function(result) { $('#edit_ads_form tbody').prepend(result); $(result).find('td.select-ad input').attr('checked','checked').click(); }); Assume that the post works correctly and returns a correct pre-built <tr> with some <td>s. Here's the weirdness: the $(result).find() line finds the correct input (which is a checkbox, as it's the only input in the cell) and runs the chained click() function correctly, but it REFUSES to set the box as checked, which I need to happen. Here's a crazy twist, too... when I get super specific and change the $(result).find() line to this (the id of the checkbox): $('#ad_' + id).click(); It checks the box, but doesn't run the click() function! If I set it to $('#ad_' + id).attr('checked','checked').click(); it runs the click function as though the box were checked, but the box remains unchecked, and if I do $('#ad_' + id).click().attr('checked','checked'); it does nothing at all. What in the world could be the matter with this? I'm running out of hair.... Thanks!

  • STLport crash (race condition, Darwin only?)

    - by Jonas Byström
    When I run STLport on Darwin I get a strange crash. (Haven't seen it anywhere else than on Mac, but exactly same thing crash on both i686 and PowerPC.) This is what it looks like in gdb: Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: 13 at address: 0x0000000000000000 [Switching to process 21097] 0x000000010120f47c in stlp_std::__node_alloc_impl::_M_allocate () It may be some setting in STLport, I noticed that Mac.h and MacOSX.h seemed far behind on features. I also know that it it must be some type of race condition, since it doesn't occur just by calling this method (implicity called). The crash happens mainly when I push the system, running 10 simultaneous threads that do a lot of string handling. Other theories I come up with have to do with compiler flags (configure script) and g++ 4.2 bugs (seems like 4.4.3 isn't on Mac yet with Objective-C support, which I need to link with). HELP!!! :) Edit: I run unit tests, which do all sorts of things. This problem arise when I start 10 threads that push the system; and it always comes down to std::string::append which eventually boils down to _M_allocate. Since I can't even get a descent dump of the code that's causing the problem, I figure I'm doing something bad. Could it be so since it's trying to execute at instruction pointer 0x000...000? Are dynlibs built as DLLs in Windows with a jump table? Could it perhaps be that such a jump table has been overwritten for some reason? That would probably explain this behavior. (The code is huge, if I run out of other ideas, I'll post a minimum crashing sample here.)

  • Flash video slooow in AIR 2 HTMLLoader component

    - by shane
    I am working on a full screen kiosk application in Flex 4/Air 2 using Flash Builder 4. We have a company training website which staff can access via the kiosk, and the main content is interactive flash training videos. Our target machines are by no means 'beefy', they are Atom n270s @ 1.6Ghz with 1Gb RAM. As it stands the videos are all but unusable when used from within the Air application, the application becomes completely unresponsive (100% cpu usage, click events take approx 5-10 seconds to register). So far I have tried: increasing the default frame rate from 24fps to 60. No improvement. nativeWindow.stage.frameRate = 60; running the videos in a stripped down version of my app, just a full screen HTMLLoader component pointed at the training website. No better than before. disabled hyper threading. The Atom CPU is split into two virtual cores, and the AIR app was only able to use one thread so maxed out at 50% CPU usage. Since the kiosk will only run the AIR app I am happy to loose hyper threading to increase the performance of the Air app. Marginal Improvement. The same website with the same videos is responsive if viewed in ie7 on the same machine, although Internet Explorer takes advantage of the CPU’s hyper threading. The flash videos are built with Adobe Captivate and from what I understand employee JavaScript to relay results back to the server. I will add more information about the video content asap as the training guru is back in the office later this week.

  • Odd behaviour with PHP's in_array function.

    - by animuson
    I have a function that checks multiple form items and returns either boolean(true) if the check passed or the name of the check that was run if it didn't pass. I built the function to run multiple checks at once, so it will return an array of these results (one result for each check that was run). When I run the function, I get this array result: Array ( [0] => 1 [1] => password [2] => birthday ) // print_r array(3) { [0]=> bool(true) [1]=> string(8) "password" [2]=> string(8) "birthday" } // var_dump The 'username' check passed and the 'password' and 'birthday' checks both failed. Then I am using simple in_array statements to determine which ones failed, like so: $results = $ani->e->vld->simulate("register.php", $checks); die(var_dump($results)); // Added after to see what array was being returned if (in_array("username", $results)) // do something if (in_array("password", $results)) // do something if (in_array("birthday", $results)) // do something The problem I'm having is that the 'username' line is still executing, even those 'username' is not in the array. It executes all three statements as if they were all true for some reason. Why is this? I thought maybe that the bool(true) was automatically causing the function to return true for every result without checking the rest of the array, but I couldn't find any documentation that would suggest that very odd functionality.
