  • BizTalk SMTP Message Part Getting XML Encoding

    - by alram
    I have a email multi-part message which I am using to send failed message routing from the messagebox to a business users mailbox. Email{ Body - RawString; OriginalMessage - string}; The original message gets set from the received message that activates the orchestration. For example assume the original failed message is from a Flat file that failed disassembly with the contents: Order,1,2,3,4,5,<6>, I set the message using: Email.OriginalMessage = MyUtil.XlangMsgToStringMethod(FailedMessage);// XmlDocument type, this can be malformed xml, valid xml, or flat file that fails in disassembler. I can then write to the event log to test whats in Email.OriginalMessage: System.Diagnostics.EventLog.WriteEntry("BizTalk Server 2006", Email.OriginalMessage, Information); // This displays the correct original message "Order, 1,2,3,4,5,<6," When the email is delivered using a SMTP server and a dynamic send port, with the attachment set to text/plain mime type, the original message gets xml encoding escaped and wrapped in xml: <?xml version="1.0"?> <string>Order, 1,2,3,4,5,&lt;6&gt;,</string> Any ideas why? The SMTP port has passthrutransmit as pipeline. Thanks.

  • Emulating a web browser

    - by Sean
    Hello, we are tasked with basically emulating a browser to fetch webpages, looking to automate tests on different web pages. This will be used for (ideally) console-ish applications that run in the background and generate reports. We tried going with .NET and the WatiN library, but it was built on a Marshalled IE, and so it lacked many features that we hacked in with calls to unmanaged native code, but at the end of the day IE is not thread safe nor process safe, and many of the needed features could only be implemented by changing registry values and it was just terribly unflexible. Proxy support JavaScript support- we have to be able to parse the actual DOM after any javascript has executed (and hopefully an event is raised to handle any ajax calls) Ability to save entire contents of page including images FROM THE loaded page's CACHE to a separate location ability to clear cookies/cache, get the cookies/cache, etc. Ability to set headers and alter post data for any browser call And for the love of drogs, an API that isn't completely cryptic Languages acceptable C++, C#, Python, anything that can be a simple little console application that doesn't have a retarded syntax like Ruby. From my own research, and believe me I am terrible at google searches, I have heard good things about WebKit... would the Qt module QtWebKit handle all these features?

  • how to better (inambiguaously) use the terms CAPTCHA and various types of interactions?

    - by vgv8
    I am working on survey of state-of-the-art and trends of spam prevention techniques. I observe that non-intrusive, transparent to visitor spam prevention techniques (like context-based filtering or honey traps) are frequently called non-captcha. Is it correct understanding of term CAPTCHA which is "type of challenge-response [ 2 ]test used in computing to ensure that the response is not generated by a compute" [ 1 ] and challenge-response does not seem to imply obligatory human involvement. So, which understanding (definition) of term and classification I'd better to stick with? How would I better call CAPTCHA without direct human interaction in order to avoid ambiguity and confusion of terms understnding? How would I better (succinctly and unambiguously) coin the term for captchas requiring human interaction but without typing into textbox? How would I better (succinctly and unambiguously) coin the terms to mark the difference between human interaction with images (playing, drag&dropping, rearranging, clicking with images) vs. just recognizing them (and then typing into a textbox the answer without interaction with images)? PS. The problem is that recognition of a wiggled word in an image or typing the answer to question is also interaction and when I start to use the terms "interaction", "interactive", "captcha", "protection", "non-captcha", "non-interactive", "static", "dynamic", "visible", "hidden" the terms overlap ambiguously with which another (especailly because the definitions or their actual practice of usage are vague or contradictive).

  • PHP Shopping Cart Script - When to empty cart?

    - by john
    Im working on a shopping cart script in php and need some advice on how to handle the final process. Once the customer has entered items into the cart, chosen shipping option, and then clicked the checkout button, they are then redirected to a paypal button which is dynamically generated using BMCreateButton. My question is, when is the best time to empty the customers cart? I have set up the auto return feature on paypal, which i was goin to use to then empty the cart, but its not very good as customers have to click a link in order to redirect. So should i empty it when they click the checkout button just before the dynamic button? I can also use these setting in php to prevent cach back button issues // Date in the past header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Always modified header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // HTTP/1.1 header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false); // HTTP/1.0 header("Pragma: no-cache"); What would to guys recommend? cheers.

  • RegularExpression Validator doesn't display error message.

    - by Rudi Ramey
    I have a regular expression validation control initialized to validate a textbox control. I want users to be able to enter U.S. Currency values ($12,115.85 or 1500.22 etc.). I found a regular expression off of regexlib website that does the trick. The validation control seems to be working except for one crucial thing. If invalid data is entered, the validation text dispalys (a red "*" next to the textbox), but the page will still submit and the error message won't pop up... I thought that the error message is supposed to display and the page won't submit if the validation control detects invalid data. Isn't this automatic with ASP .NET? I have searched extensively on how to create validation controls, but haven't found anything different than what I am already doing. Can anyone tell me what I am doing wrong here? <asp:TextBox ID="txtActualCost" runat="server" Width="120px" CausesValidation="true"></asp:TextBox> <asp:RegularExpressionValidator ID="regExValActualCost" ControlToValidate="txtActualCost" Text="*" ValidationExpression="^\$?(\d{1,3}(\,\d{3})*|(\d+))(\.\d{2})?$" ErrorMessage="Please enter a valid currency value for 'Actual Cost'" Display="Dynamic" EnableClientScript="true" runat="server" />

  • How to mmap the stack for the clone() system call on linux?

    - by Joseph Garvin
    The clone() system call on Linux takes a parameter pointing to the stack for the new created thread to use. The obvious way to do this is to simply malloc some space and pass that, but then you have to be sure you've malloc'd as much stack space as that thread will ever use (hard to predict). I remembered that when using pthreads I didn't have to do this, so I was curious what it did instead. I came across this site which explains, "The best solution, used by the Linux pthreads implementation, is to use mmap to allocate memory, with flags specifying a region of memory which is allocated as it is used. This way, memory is allocated for the stack as it is needed, and a segmentation violation will occur if the system is unable to allocate additional memory." The only context I've ever heard mmap used in is for mapping files into memory, and indeed reading the mmap man page it takes a file descriptor. How can this be used for allocating a stack of dynamic length to give to clone()? Is that site just crazy? ;) In either case, doesn't the kernel need to know how to find a free bunch of memory for a new stack anyway, since that's something it has to do all the time as the user launches new processes? Why does a stack pointer even need to be specified in the first place if the kernel can already figure this out?

  • What AOP tools exist for doing aspect-oriented programming at the assembly language level against x8

    - by JohnnySoftware
    Looking for a tool I can use to do aspect-oriented programming at the assembly language level. For experimentation purposes, I would like the code weaver to operate native application level executable and dynamic link libraries. I have already done object-oriented AOP. I know assembly language for x86 and so forth. I would like to be able to do logging and other sorts of things using the familiar before/after/around constructs. I would like to be able to specify certain instructions or sequences/patterns of consecutive instructions as what to do a pointcut on since assembly/machine language is not exactly the most semantically rich computer language on the planet. If debugger and linker symbols are available, naturally, I would like to be able to use them to identify subroutines' entry points , branch/call/jump target addresses, symbolic data addresses, etc. I would like the ability to send notifications out to other diagnostic tools. Thus, support for sending data through connection-oriented sockets and datagrams is highly desirable. So is normal logging to files, UI, etc. This can be done using the action part of an aspect to make a function call, but then there are portability issues so the tool needs to support a flexible, well-abstracted logging/notifying mechanism with a clean, simple yet flexible. The goal is rapid-QA. The idea is to be able to share aspect source code braodly within communties as well as publicly. So, there needs to be a declarative security policy file that users can share. This insures that nothing untoward that is hidden directly or indirectly in an aspect source file slips by the execution manager. The policy file format needs to be simple to read, write, modify, understand, type-in, edit, and generate. Sort of like Java .policy files. Think the exact opposite of anything resembling XML Schema files and you get the idea. Is there such a tool in existence already?

  • Mac OS X: Getting detailed process information (specifically its launch arguments) for arbitrary run

    - by Jasarien
    I am trying to detect when particular applications are launched. Currently I am using NSWorkspace, registering for the "did launch application" notification. I also use the runningApplications method to get apps that are currently running when my app starts. For most apps, the name of the app bundle is enough. I have a plist of "known apps" that I cross check with the name of that passed in the notification. This works fine until you come across an app that acts as a proxy for launching another application using command line arguments. Example: The newly released Portal on the Mac doesn't have a dedicated app bundle. Steam can create a shortcut, which serves as nothing more than to launch the hl2_osx app with the -game argument and portal as it's parameter. Since more Source based games are heading to the Mac, I imagine they'll use the same method to launch, effectively running the hl2_osx app with the -game argument. Is there a nice way to get a list of the arguments (and their parameters) using a Cocoa API? NSProcessInfo comes close, offering an `-arguments' method, but only provides information for its own process... NSRunningApplication offers the ability to get information about arbitrary apps using a PID, but no command line args... Is there anything that fills the gap between the two? I'm trying not to go down the route of spawning an NSTask to run ps -p [pid] and parsing the output... I'd prefer something more high level.

  • Using SoapExtensionAttributes on client side with async web methods

    - by Maxim Polishchuk
    Hey, I have a simple question. I implemented custom soap extension and registered it into client application configuration file. It works fine. (I would like to implement progress bar functionality like http://msdn.microsoft.com/en-us/library/aa480520.aspx) But I don't like some thing - custom soap extension is invoked by every call of my web service. In order to fix this situation (call WS just by required methods) I implemented custom SoapExtensionAttribute like below: [AttributeUsage(AttributeTargets.Method)] public class CustomSoapExtensionAttribute : SoapExtensionAttribute { public override int Priority { get; set; } public CustomSoapExtensionAttribute() : this (1) { } public CustomSoapExtensionAttribute(int priority) { Priority = priority; } public override Type ExtensionType { get { return typeof(CustomSoapExtension); } } } I added this attribute to required methods of web service proxy classes (and removed registration into client configuration file). My soap extension doesn't invoke when required web methods are calling. Can someone help me to solve this problem or select any other solution? Anotherone, I don't know it is important or not - my required methods are async web methods. Best regards, Maxim

  • A Django form for entering a 0 to n email addresses

    - by Erik
    I have a Django application with some fairly common models in it: UserProfile and Organization. A UserProfile or an Organization can both have 0 to n emails, so I have an Email model that has a GenericForeignKey. UserProfile and Organization Models both have a GenericRelation called emails that points back to the Email model (summary code provided below). The question: what is the best way to provide an Organization form that allows a user to enter organization details including 0 to n email addresses? My Organization create view is a Django class-based view. I'm leading towards creating a dynamic form and an enabling it with Javascript to allow the user to add as many email addresses as necessary. I will render the form with django-crispy-forms. I've thought about doing this with a formset embedded within the form, but this seems like overkill for email addresses. Embedding a formset in a form delivered by a class-based view is cumbersome too. Note that the same issue occurs with the Organization fields phone_numbers and locations. emails.py: from django.db import models from parent_mixins import Parent_Mixin class Email(Parent_Mixin,models.Model): email_type = models.CharField(blank=True,max_length=100,null=True,default=None,verbose_name='Email Type') email = models.EmailField() class Meta: app_label = 'core' organizations.py: from emails import Email from locations import Location from phone_numbers import Phone_Number from django.contrib.contenttypes import generic from django.db import models class Organization(models.Model): active = models.BooleanField() duns_number = models.CharField(blank=True,default=None,null=True,max_length=9) # need to validate this emails = generic.GenericRelation(Email,content_type_field='parent_type',object_id_field='parent_id') legal_name = models.CharField(blank=True,default=None,null=True,max_length=200) locations = generic.GenericRelation(Location,content_type_field='parent_type',object_id_field='parent_id') name = models.CharField(blank=True,default=None,null=True,max_length=200) organization_group = models.CharField(blank=True,default=None,null=True,max_length=200) organization_type = models.CharField(blank=True,default=None,null=True,max_length=200) phone_numbers = generic.GenericRelation(Phone_Number,content_type_field='parent_type',object_id_field='parent_id') taxpayer_id_number = models.CharField(blank=True,default=None,null=True,max_length=9) # need to validate this class Meta: app_label = 'core' parent_mixins.py from django.contrib.contenttypes.models import ContentType from django.contrib.contenttypes import generic from django.db import models class Parent_Mixin(models.Model): parent_type = models.ForeignKey(ContentType,blank=True,null=True) parent_id = models.PositiveIntegerField(blank=True,null=True) parent = generic.GenericForeignKey('parent_type', 'parent_id') class Meta: abstract = True app_label = 'core'

  • WCF events in server-side

    - by Eisenrich
    Hi all, I'm working on an application in WCF and want to receive events in the server side. I have a web that upon request needs to register a fingerprint. The web page request the connection of the device and then every second for 15 seconds requests the answer. The server-side code is apparently "simple" but doesn't work. Here is it: [ServiceContract] interface IEEtest { [OperationContract] void EEDirectConnect(); } class EETest : IEEtest { public void EEDirectConnect() { CZ ee = new CZ(); // initiates the device dll ee.Connect_Net("192.168.1.200", 4011); ee.OnFinger += new _IEEEvents_OnFingerEventHandler(ee_OnFinger); } public void ee_OnFinger() { //here i have a breakpoint; } } every time I put my finger, it should fire the event. in fact if I static void Main() { EETest pp = new EETest(); pp.EEDirectConnect(); } It works fine. but from my proxy it doesn't fire the event. do you have any tips, recommendations, or can you see the error? Thanks everyone.

  • Connecting repeatable and non-repeatble backgrounds without a seam

    - by Stiggler
    I have a 700x300 background repeating seamlessly inside of the main content-div. Now I'd like to attach a div at the bottom of the content-div, containing a different background image that isn't repeatable, connecting seamlessly with the repeatable background above it. Essentially, the non-repeatable image will look like the end piece of the repeatable image. Due to the nature of the pattern, unless the full 300px height of the background image is visible in the last repeat of the content-div's backround, the background in the div below won't seamlessly connect. Basically, I need the content div's height to be a multiple of 300px under all circumstances. What's a good approach to this sort of problem? I've tried resizing the content-div on loading the page, but this only works as long as the content div doesn't contain any resizing, dynamic content, which is not my case: function adjustContentHeight() { // Setting content div's height to nearest upper multiple of column backgrounds height, // forcing it not to be cut-off when repeated. var contentBgHeight = 300; var contentHeight = $("#content").height(); var adjustedHeight = Math.ceil(contentHeight / contentBgHeight); $("#content").height(adjustedHeight * contentBgHeight); } $(document).ready(adjustContentHeight); What I'm looking for there is a way to respond to a div resizing event, but there doesn't seem to be such a thing. Also, please assume I have no access to the JS controlling the resizing of content in the content-div, though this is potentially a way of solving the problem. Another potential solution I was thinking off was to offset the background image in the bottom div by a certain amount depending on the height of the content-div. Again, the missing piece seems to be the ability to respond to a resize event.

  • Checking if an array contains all elements of another array

    - by mozcelikors
    I'm designing an electrical engineering application. However, i'm stuck on this: I have the following array <?php // Static Array $GroupOfEight = array ( array(0,1,3,2,4,5,7,6), array(4,5,6,7,16,12,13,14), array(12,13,15,14,8,9,11,10), array(2,6,14,10,3,7,15,11), array(1,3,5,7,13,15,9,11), array(0,4,12,8,1,5,13,9), array(0,1,3,2,8,9,11,10) ); ?> And I have another array, but this one is one dimensional. <?php $myStack = array(0,1,3,2,4,5,7,6); //Dynamic, gets value by POST method. ?> What I want to do is to check if $myStack is equal to any sub array of $GroupOfEight array. ( Number ordering is not important. The script should just check if every elements contained. It's not important if their order is same or not. ) Here is what I've done to solve the issue so far: <?php //Check if stackArray contains 8group for($i=0; $i<count($GroupOfEight);$i++) for($j=0; $j<count($GroupOfEight[$i]); $j++){ //$containsSearch = count(array_intersect($search_this,$all)) == count($search_this); $containsSearch = count(array_intersect($stackArray,$GroupOfEight[$j])) == count($stackArray); echo $containsSearch; } ?> Please help me correct my code or introduce me the solution of this issue, Thanks.

  • Custom JSTL tags with body

    - by Mickel
    Hi, We are going to use JSTL and custom JSTL-tags for some sort of template-engine in our JSP/spring-project. Is there a way to create a tag that looks similar like this: <div id="site"> <div id="header">Some title</div> <div id="navigation"> SOME DYNAMIC CONTENT HERE </div> <div id="content"> ${content} </div> <div id="footer"></div> </div> and use it like this: <mytags:template> <h1>Title</h1> <p>My content!</p> </mytags:template> i.e. use body-content inside a custom JSTL-tag... This works: <mytags:template content="some content... not HTML" /> but is not very useful in our case.

  • jQuery performance

    - by jAndy
    Hi Folks, imagine you have to do DOM manipulation like a lot (in my case, it's kind of a dynamic list). Look at this example: var $buffer = $('<ul/>', { 'class': '.custom-example', 'css': { 'position': 'absolute', 'top': '500px' } }); $.each(pages[pindex], function(i, v){ $buffer.append(v); }); $buffer.insertAfter($root); "pages" is an array which holds LI elements as jQuery object. "$root" is an UL element What happens after this code is, both UL's are animated (scrolling) and finally, within the callback of animate this code is executed: $root.detach(); $root = $buffer; $root.css('top', '0px'); $buffer = null; This works very well, the only thing I'm pi**ed off is the performance. I do cache all DOM elements I'm laying a hand on. Without looking too deep into jQuery's source code, is there a chance that my performance issues are located there? Does jQuery use DocumentFragments to append things? If you create a new DOM element with var new = $('<div/>') it is only stored in memory at this point isnt it?

  • Does Firefox on OS X Lion make use of Full Page Zoom for the touchpad? How to customize behavior?

    - by Steven Lu
    I really like the smooth pinch-zoom of Safari using the touchpad, but the two-finger scroll on Firefox is so much better than the scrolling performance in Safari. So I really like to use Firefox, but then I miss out on two-finger-double-tap to zoom to paragraph width, and the smooth pinch gesture zoom. What I'm wondering is if it is possible to write a Firefox Extension to improve the update rate of the full-page zoom in Firefox that is already functioning via the touchpad pinch gesture. I feel like it is specifically programmed to zoom at certain zoom levels: 100%, 120%, 150% (these are guesses of mine) but I think it would be great if I can get some more control there to make it work more like the zoom functionality in Safari. Also the two-finger-double-tap on a paragraph or element to zoom to it would be really awesome as well. https://developer.mozilla.org/en/Full_page_zoom This seems to indicate (if "full page zoom" is what I think it is) that an extension has the ability to zoom to an arbitrary scale factor, but what remains is to find out if it is possible to obtain or hook the touchpad pinch gesture. Update: I have updated the toolkit.zoomManager.zoomValues option in about:config to include more zoom levels: .3,.5,.67,.8,.9,1,1.01,1.02,1.03,1.04,1.05,1.06,1.07,1.08,1.09,1.1,1.2,1.33,1.5,1.7,2,2.4,3 Notice how I inserted a bunch of entries between 1 and 1.1. But it isn't switching between them any faster (why would it?) so it's less usable than before because of waiting for it to respond fast enough. It's clear that re-rendering the page at a different zoom level requires time and in order for the zoom to be dynamic, some kind of screen capture and scale effect must be performed (which is what Safari does). I guess such a thing is probably doable but I don't think I could pull it off. :-/

  • Manipulating jQuery to retrieve the onclick function of an item which lies directly below the curren

    - by Stevie Jenowski
    First off, I want to thank you for looking into my question as I really do appreciate your time. I've built a list of items using php by having a foreach loop cycle through an associative array printing the array data as parameters of an onclick function call and gives each item it cycles through an ID of $thecount. All items retrieved have the same parent div and calls the very same onclick function, only with 11 different parameters. My question is how do I go about calling the onClick("function();") of an item directly below the current focus, making it the new focus, only without a physical click? If this is confusing to you whatsoever, I'm essentially building a dynamic playlist, and I've already implemented the listener for when the player's current item has finished playing, Now I'm having trouble grasping how I'd go about having the next item in the list become the new focus while also calling it's specific onClick() function once the player returns that it has finished with the current file. All without any user interaction besides the initial play call. If it helps I'm using the most recent release of Longtails' JW Player and once again thank you very much for your time!

  • Converting an input text value to a decimal number

I've wrote a simple function which recives my input text value and converts it to a decimal number ready to be stored in the database. <?php function unit ($value, $decimal_point = 2) { return number_format (str_replace (",", ".", strip_tags (trim ($value))), $decimal_point); } ?> I've resolved something like AbdlBsF5%?nl with some jQuery code for replace and some regex to keep only numbers, dots and commas. In some country, people uses the comma , to send decimal numbers, so a number like 72.08 is wrote like 72,08. I'd like avoid to forcing people to change their usual chars and I've decided to use a jQuery to keep this too. Now every web developer knows the last validation must be handled by the dynamic page for security reasons. So my answer is should I use something like unit (); function to store data or shoul I also check if users inserts invalid chars like letters or something else? If I try this and send letters, the query works without save the invalid data, I think this isn't bad, but I could easily be wrong because I'm a rookie. What kind of method should I use if I want a number like 99999.99 for my query?

  • Re-using aggregate level formulas in SQL - any good tactics?

    - by Cade Roux
    Imagine this case, but with a lot more component buckets and a lot more intermediates and outputs. Many of the intermediates are calculated at the detail level, but a few things are calculated at the aggregate level: DECLARE @Profitability AS TABLE ( Cust INT NOT NULL ,Category VARCHAR(10) NOT NULL ,Income DECIMAL(10, 2) NOT NULL ,Expense DECIMAL(10, 2) NOT NULL ) ; INSERT INTO @Profitability VALUES ( 1, 'Software', 100, 50 ) ; INSERT INTO @Profitability VALUES ( 2, 'Software', 100, 20 ) ; INSERT INTO @Profitability VALUES ( 3, 'Software', 100, 60 ) ; INSERT INTO @Profitability VALUES ( 4, 'Software', 500, 400 ) ; INSERT INTO @Profitability VALUES ( 5, 'Hardware', 1000, 550 ) ; INSERT INTO @Profitability VALUES ( 6, 'Hardware', 1000, 250 ) ; INSERT INTO @Profitability VALUES ( 7, 'Hardware', 1000, 700 ) ; INSERT INTO @Profitability VALUES ( 8, 'Hardware', 5000, 4500 ) ; SELECT Cust ,Profit = SUM(Income - Expense) ,Margin = SUM(Income - Expense) / SUM(Income) FROM @Profitability GROUP BY Cust SELECT Category ,Profit = SUM(Income - Expense) ,Margin = SUM(Income - Expense) / SUM(Income) FROM @Profitability GROUP BY Category SELECT Profit = SUM(Income - Expense) ,Margin = SUM(Income - Expense) / SUM(Income) FROM @Profitability Notice how the same formulae have to be used at the different aggregation levels. This results in code duplication. I have thought of using UDFs (either scalar or table valued with an OUTER APPLY, since many of the final results may share intermediates which have to be calculated at the aggregate level), but in my experience the scalar and multi-statement table-valued UDFs perform very poorly. Also thought about using more dynamic SQL and applying the formulas by name, basically. Any other tricks, techniques or tactics to keeping these kinds of formulae which need to be applied at different levels in sync and/or organized?

  • Out of Core Implementation of a Quadtree

    - by Nima
    Hi, I am trying to build a Quadtree data structure(or let's just say a tree) on the secondary memory(Hard Disk). I have a C++ program to do so and I use fopen to create the files. Also, I am using tesseral coding to store each cell in a file named with its corresponding code to store it on the disk in one directory. The problem is that after creating about 1,100 files, fopen just returns NULL and stops creating new files. I can create further files manually in that directory, but using C++ it can not create any further files. I know about max limit of inode on ext3 filesystem which is (from Wikipedia) 32,000 but mine is way less than that, also note that I can create files manually on the disk; just not through fopen. Also, I really appreciate any idea regarding the best way to store a very dynamic quadtree on disk(I need the nodes to be in separate files and the quadtree might have a depth of 50). Using nested directories is one idea, but I think it will slow down the performance because of following the links on the filesystem to access the file. Thanks, Nima

  • Value is not changing in the javascript variable on the onClick event

    - by Chetan sharma
    I am trying to implement a dynamic search jquery and php, but I am not able to change the value of a javascript variable on my onclick event. <script type="text/javascript"> var main_category = '<?php echo $main_category?>'; var main_url = '<?php echo $url?>get/' + encodeURIComponent(main_category) + '/'; var container_id = '<?php echo $unique_id?>content_area'; //name $('#<?php echo $unique_id?>search_by_name').autocomplete('<?php echo $url?>get_autocomplete_data/' + encodeURIComponent(main_category) + '/names/', { matchContains: "word", autoFill: true, width: 310 });$('#<?php echo $unique_id?>search_by_name').result(function (event, data){ var url = main_url + 'search/title/' + encodeURIComponent(data); load_div(container_id, url); }); //on click of displayed categories $('[rel="<?php echo $unique_id?>sub_category"]').click(function (){ window['main_category'] = this.title; $('#<?php echo $unique_id?>category').html('' +main_category+ ''); return false; }); }); </script> It changes the value when on click is fired //on click of displayed categories $('[rel="<?php echo $unique_id?>sub_category"]').click(function (){ window['main_category'] = this.title; $('#<?php echo $unique_id?>category').html('' +main_category+ ''); return false; }); but when after that i add data for the search it still searches for the old category $('#<?php echo $unique_id?>search_by_name').result(function (event, data){ var url = main_url + 'search/title/' + encodeURIComponent(data); load_div(container_id, url); }); "main_category" value is not changing in the "main_url"

  • Maven webapp with Eclipse and WTP plugin deploy files in stranges ways in Tomcat

    - by hokkos
    Hi, I use Eclipse J2EE 3.5 with Maven and tomcat. To deploy my maven webapp with WTP I added a Dynamic Web Module facet and changed the "org.eclipse.wst.common.component" file of the project because the webapp is not in a WebContent directory, here is the content of the file: <?xml version="1.0" encoding="UTF-8"?> <project-modules id="moduleCoreId" project-version="1.5.0"> <wb-module deploy-name="tkey-ca-web"> <wb-resource deploy-path="/" source-path="/src/main/webapp"/> <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/java"/> <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/resources"/> <property name="context-root" value="toto"/> <property name="java-output-path" value="/toto/target/classes"/> </wb-module> </project-modules> But it never deploy the content correctly, in "workspace.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\toto\" the directory structure is correct with WEB-INF and META-INF but empty, the jsp, html, css files are in "workspace.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\toto\WEB-INF\classes\" with another WEB-INF and META-INF structure but with the files. I don't understand this at all, thanks.

  • Solving problems involving more complex data structures with CUDA

    - by Nils
    So I read a bit about CUDA and GPU programming. I noticed a few things such that access to global memory is slow (therefore shared memory should be used) and that the execution path of threads in a warp should not diverge. I also looked at the (dense) matrix multiplication example, described in the programmers manual and the nbody problem. And the trick with the implementation seems to be the same: Arrange the calculation in a grid (which it already is in case of the matrix mul); then subdivide the grid into smaller tiles; fetch the tiles into shared memory and let the threads calculate as long as possible, until it needs to reload data from the global memory into shared memory. In case of the nbody problem the calculation for each body-body interaction is exactly the same (page 682): bodyBodyInteraction(float4 bi, float4 bj, float3 ai) It takes two bodies and an acceleration vectors. The body vector has four components it's position and the weight. When reading the paper, the calculation is understood easily. But what is if we have a more complex object, with a dynamic data structure? For now just assume that we have an object (similar to the body object presented in the paper) which has a list of other objects attached and the number of objects attached is different in each thread. How could I implement that without having the execution paths of the threads to diverge? I'm also looking for literature which explains how different algorithms involving more complex data structures can be effectively implemented in CUDA.
