  • Grails validateable not work for non-persistent domain class

    - by Hoàng Long
    I followed the instruction here: http://www.grails.org/doc/latest/guide/7.%20Validation.html and added into config.groovy: grails.validateable.classes = [liningtest.Warm'] Then added in src/groovy/Warm.groovy (it's a non-persistent domain class): package liningtest import org.codehaus.groovy.grails.validation.Validateable class Warm { String name; int happyCite; Warm(String n, int h) { this.name = n; this.happyCite = h; } static constraints = { name(size: 1..50) happyCite(min: 100) } } But it just doesn't work (both "blank false" & "size: 0..25") for the "hasErrors" function. It always returns false, even when the name is 25. Is this a Grails bug, if yes, is there any work-around? I'm using Grails 1.3.3 UPDATE: I have updated the simplified code. And now I know that constraint "size" can't be used with "blank", but still does not work. My test class in test/unit/liningtest/WarmTests.groovy package liningtest import grails.test.* class WarmTests extends GrailsUnitTestCase { protected void setUp() { super.setUp() } protected void tearDown() { super.tearDown() } void testSomething() { def w = new Warm('Hihi', 3) assert (w.happyCite == 3) assert (w.hasErrors() == true) } } And the error I got: <?xml version="1.0" encoding="UTF-8" ?> <testsuite errors="1" failures="0" hostname="evolus-50b0002c" name="liningtest.WarmTests" tests="1" time="0.062" timestamp="2010-12-16T04:07:47"> <properties /> <testcase classname="liningtest.WarmTests" name="testSomething" time="0.062"> <error message="No signature of method: liningtest.Warm.hasErrors() is applicable for argument types: () values: [] Possible solutions: hashCode()" type="groovy.lang.MissingMethodException">groovy.lang.MissingMethodException: No signature of method: liningtest.Warm.hasErrors() is applicable for argument types: () values: [] Possible solutions: hashCode() at liningtest.WarmTests.testSomething(WarmTests.groovy:18) </error> </testcase> <system-out><![CDATA[--Output from testSomething-- ]]></system-out> <system-err><![CDATA[--Output from testSomething-- ]]></system-err> </testsuite> UPDATE 2: When I don't use Unit test, but try to call hasErrors in the controller, it runs but return false value. (hasErrors return false with Warm('Hihi', 3) ). Does anyone has a clue?

  • Profile memory-performance for part of an rails project

    - by Florian Pilz
    I want to test the profile usage of an important library-class of my rails-project. It uses ActiveRecord so I need all rails dependencies to profile it. As far as I know, I need a patched ruby (rubygc) so script/profile and script/benchmark can track memory usage. I tried to follow this official guide to patch the source code of ruby 1.8.6 (p399) and 1.8.7 (p248), but both fail with the following message: patching file gc.c Hunk #2 succeeded at 50 with fuzz 2 (offset 2 lines). Hunk #3 succeeded at 87 with fuzz 2 (offset 6 lines). Hunk #4 succeeded at 153 with fuzz 1 (offset 45 lines). Hunk #5 succeeded at 409 with fuzz 2 (offset 274 lines). Hunk #6 FAILED at 462. Hunk #7 FAILED at 506. Hunk #8 FAILED at 520. Hunk #9 FAILED at 745. Hunk #10 FAILED at 754. Hunk #11 FAILED at 923. Hunk #12 succeeded at 711 (offset 46 lines).

Hunk #28 succeeded at 2628 (offset 102 lines). 8 out of 28 hunks FAILED -- saving rejects to file gc.c.rej patching file intern.h Hunk #1 succeeded at 268 (offset 15 lines). I also tried to use ruby-prof, but I always get the error "uninitialized constant RubyProf::Test". I don't know how to use the gem "memory" and neither "memprof" nor "bleak_house" could be installed successfully. If I get a patched ruby running, I should be fine. But any other possibility to profile the memory of library classes are welcome. Thanks for helping!

  • Silverlight? WPF? or Windows Form?

    - by Amit
    After Silverlight 4.0 has been released with new WPF, I am kind of confused with these technologies: Silverlight? WPF? Windows Form? The main motive that we want to achieve for BIG business project is following: Performance Security And platform independent** If I consider all above three points then only Silverlight is the option as I don’t want people buying emulator on MacOS for WPF or Windows Form. Now how good the Silverlight is for Business applications, I was completely against when Silverlight 2.0 was in the market but now it is Silverlight 4.0 and they have provided many new features (but still basics) that is required in any challenging business applications. Comparing Silverlight and WPF -* Silverlight and WPF are very new technology and if I'd to compare from these two then I'd prefer WPF because it can be considered stable and mature. But it is not same as Windows Form. -* If I go with Silverlight then I am sure about keep updating to the latest version of Silverlight. I remembered when we were developing software for version 2.0 then we'd to create our own framework with dynamic loading DLL, and then Navigation concept. But everything was got changed once Silverlight 3.0 came. I don't want this to be happening with this new product. -* If we go with WPF then we don't get the platform independence. Now, why not we just focus on making WPF and then move to Silverlght. As someone (Tim?) from Microsoft has said that the idea is to make Silverlight as close as WPF. But if that is the case then why XAML structure is different; I will not be convinced with by saying that .Net framework for SL is too small.. well the difference is coming from the namespace ? I was searching on this subject and found "Microsoft WPF-Silverlight Comparison Whitepaper v1.1.pdf". This guide is very good that gives you ins-outs about how can we build common apps that runs on both. But again, it is comparing Silverlight 2 and not 4. I am sure many architect/ developers/ project managers must be facing similar kind of questions in their premises and wants to initiate this discussion, if it has not been :). We've still got 2 weeks to make this decision, so I'm expecting everyone to participate, gurus?

  • Adding NavigationControl to a TabBar Application containing UITableViews

    - by kungfuslippers
    Hi, I'm new to iPhone dev and wanted to get advice on the general design pattern / guide for putting a certain kind of app together. I'm trying to build a TabBar type application. One of the tabs needs to display a TableView and selecting a cell from within the table view will do something else - maybe show another table view or a web page. I need a Navigation Bar to be able to take me back from the table view/web page. The approach I've taken so far is to: Create an app based around UITabBarController as the rootcontroller i.e. @interface MyAppDelegate : NSObject <UIApplicationDelegate> { IBOutlet UIWindow *window; IBOutlet UITabBarController *rootController; } Create a load of UIViewController derived classes and associated NIBs and wire everything up in IB so when I run the app I get the basic tabs working. I then take the UIViewController derived class and modify it to the following: @interface MyViewController : UIViewController<UITableViewDataSource, UITableViewDelegate> { } and I add the delegate methods to the implementation of MyViewController - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 2; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } if (indexPath.row == 0) { cell.textLabel.text = @"Mummy"; } else { cell.textLabel.text = @"Daddy"; } return cell; } Go back to IB , open MyViewController.xib and drop a UITableView onto it. Set the Files Owner to be MyViewController and then set the delegate and datasource of the UITableView to be MyViewController. If I run the app now, I get the table view appearing with mummy and daddy working nicely. So far so good. The question is how do I go about incorporating a Navigation Bar into my current code for when I implement: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath() { // get row selected NSUInteger row = [indexPath row]; if (row == 0) { // Show another table } else if (row == 1) { // Show a web view } } Do I drop a NavigationBar UI control onto MyControllerView.xib ? Should I create it programmatically? Should I be using a UINavigationController somewhere ? I've tried dropping a NavigationBar onto my MyControllerView.xib in IB but its not shown when I run the app, only the TableView is displayed.

  • How to access static members in a Velocity template?

    - by matt b
    I'm not sure if there is a way to do this in Velocity or not: I have a User POJO which a property named Status, which looks like an enum (but it is not, since I am stuck on Java 1.4), the definition looks something like this: public class User { // default status to User private Status status = Status.USER; public void setStatus(Status status) { this.status = status; } public Status getStatus() { return status; } And Status is a static inner class: public static final class Status { private String statusString; private Status(String statusString) { this.statusString = statusString; } public final static Status USER = new Status("user"); public final static Status ADMIN = new Status("admin"); public final static Status STATUS_X = new Status("blah"); //.equals() and .hashCode() implemented as well } With this pattern, a user status can easily be tested in a conditional such as if(User.Status.ADMIN.equals(user.getStatus())) ... ... without having to reference any constants for the status ID, any magic numbers, etc. However, I can't figure out how to test these conditionals in my Velocity template with VTL. I'd like to just print a simple string based upon the user's status, such as: Welcome <b>${user.name}</b>! <br/> <br/> #if($user.status == com.company.blah.User.Status.USER) You are a regular user #elseif($user.status == com.company.blah.User.Status.ADMIN) You are an administrator #etc... #end But this throws an Exception that looks like org.apache.velocity.exception.ParseErrorException: Encountered "User" at webpages/include/dashboard.inc[line 10, column 21] Was expecting one of: "[" ... From the VTL User Guide, there is no mention of accessing a Java class/static member directly in VTL, it appears that the right hand side (RHS) of a conditional can only be a number literal, string literal, property reference, or method reference. So is there any way that I can access static Java properties/references in a Velocity template? I'm aware that as a workaround, I could embed the status ID or some other identifier as a reference in my controller (this is a web MVC application using Velocity as the View technology), but I strongly do not want to embed any magic numbers or constants in the view layer.

  • How to remove music/videos DRM protection and convert to Mobile Devices such as iPod, iPhone, PSP, Z

    - by tonywesley
    The music/video files you purchased from online music stores like iTunes, Yahoo Music or Wal-Mart are under DRM protection. So you can't convert them to the formats supported by your own mobile devices such as Nokia phone, Creative Zen palyer, iPod, PSP, Walkman, Zune… You also can't share your purchased music/videos with your friends. The following step by step tutorial is dedicated to instructing music lovers to how to convert your DRM protected music/videos to mobile devices. Method 1: If you only want to remove DRM protection from your protected music, this method will not spend your money. Step 1: Burn your protected music files to CD-R/RW disc to make an audio CD Step 2: Find a free CD Ripper software to convert the audio CD track back to MP3, WAV, WMA, M4A, AAC, RA… Method 2: This guide will show you how to crack drm from protected wmv, wma, m4p, m4v, m4a, aac files and convert to unprotected WMV, MP4, MP3, WMA or any video and audio formats you like, such as AVI, MP4, Flv, MPEG, MOV, 3GP, m4a, aac, wmv, ogg, wav... I have been using Media Converter software, it is the quickest and easiest solution to remove drm from WMV, M4V, M4P, WMA, M4A, AAC, M4B, AA files by quick recording. It gets audio and video stream at the bottom of operating system, so the output quality is lossless and the conversion speed is fast . The process is as follows. Step 1: Download and install the software Step 2: Run the software and click "Add…" button to load WMA or M4A, M4B, AAC, WMV, M4P, M4V, ASF files Step 3: Choose output formats. If you want to convert protected audio files, please select "Convert audio to" list; If you want to convert protected video files, please select "Convert video to" list. Step 4: You can click "Settings" button to custom preference for output files. Click "Settings" button bellow "Convert audio to" list for protected audio files Click "Settings" button bellow "Convert video to" list for protected video files Step 5: Start remove DRM and convert your DRM protected music and videos by click on "Start" button. What is DRM? DRM, which is most commonly found in movies and music files, doesn't mean just basic copy-protection of video, audio and ebooks, but it basically means full protection for digital content, ranging from delivery to end user's ways to use the content. We can remove the Drm from video and audio files legally by quick recording.

  • ASP.NET MVC Return to Previous Page

    - by Jason Enochs
    I have a basic Edit method in my controller that redirects back to a top level listing (“Index”) when the edit succeeds. Standard setup after scaffolding. I am trying to change this Edit method to redirect back to the previous page (not Index). Since my Edit method is not using the default mapped input parameter “id”, I am using that to pass the previous URL. In my Edit “get” method, I use this line to grab the previous URL and it works fine: ViewBag.ReturnUrl = Request.UrlReferrer.AbsoluteUri; I send this return URL to the Edit “post” method by using my form tag like this: @using (Html.BeginForm(new { id = ViewBag.ReturnUrl })) Now this is where the wheels fall off. I can't seem to get the URL parsed from the id parameter properly. UPDATE**** Using Gary's example as a guide, I changing my parameter name from "id" to "returnUrl" and used a hidden field to pass my parameter. Lesson: Only use the id parameter how it was intended to be used...keep it simple. It works now... Here is my updated code. // // GET: /Question/Edit/5 public ActionResult Edit(int id) { Question question = db.Questions.Find(id); ViewBag.DomainId = new SelectList(db.Domains, "DomainId", "Name", question.DomainId); ViewBag.Answers = db.Questions .AsEnumerable() .Select(d => new SelectListItem { Text = d.Text, Value = d.QuestionId.ToString(), Selected = question.QuestionId == d.QuestionId }); ViewBag.returnUrl = Request.UrlReferrer; ViewBag.ExamId = db.Domains.Find(question.DomainId).ExamId; ViewBag.IndexByQuestion = string.Format("IndexByQuestion/{0}", question.QuestionId); return View(question); } // // POST: /Question/Edit/5 [HttpPost] public ActionResult Edit(Question question, string returnUrl) { int ExamId = db.Domains.Find(question.DomainId).ExamId; if (ModelState.IsValid) { db.Entry(question).State = EntityState.Modified; db.SaveChanges(); //return RedirectToAction("Index"); return Redirect(returnUrl); } ViewBag.DomainId = new SelectList(db.Domains, "DomainId", "Name", question.DomainId); return View(question); } and I changed my form tag to this: @using (Html.BeginForm()) { <input type="hidden" name="returnUrl" value="@ViewBag.returnUrl" /> Thanks Gary

  • how to filter data from xml file for displaying only selected as nodes in treeview

    - by michale
    I have an xml file named "books.xml" provided in the link "http://msdn.microsoft.com/en-us/library/windows/desktop/ms762271(v=vs.85).aspx". What my requirement was to disaplay only the <title> from xml information as nodes in tree view. But when i did the following coding its displaying all the values as nodes like "catalog" as rootnode, book as parent node for all then author,title,genre etc as nodes but i want only root node catalogue and title as nodes not even book. Can any body guide me what modification i need to do in the exisitng logic for displaying title as nodes OpenFileDialog dlg = new OpenFileDialog(); dlg.Title = "Open XML document"; dlg.Filter = "XML Files (*.xml)|*.xml"; dlg.FileName = Application.StartupPath + "\\..\\..\\Sample.xml"; if (dlg.ShowDialog() == DialogResult.OK) { try { //Just a good practice -- change the cursor to a //wait cursor while the nodes populate this.Cursor = Cursors.WaitCursor; //First, we'll load the Xml document XmlDocument xDoc = new XmlDocument(); xDoc.Load(dlg.FileName); //Now, clear out the treeview, //and add the first (root) node treeView1.Nodes.Clear(); treeView1.Nodes.Add(new TreeNode(xDoc.DocumentElement.Name)); TreeNode tNode = new TreeNode(); tNode = (TreeNode)treeView1.Nodes[0]; //We make a call to addTreeNode, //where we'll add all of our nodes addTreeNode(xDoc.DocumentElement, tNode); //Expand the treeview to show all nodes treeView1.ExpandAll(); } catch (XmlException xExc) //Exception is thrown is there is an error in the Xml { MessageBox.Show(xExc.Message); } catch (Exception ex) //General exception { MessageBox.Show(ex.Message); } finally { this.Cursor = Cursors.Default; //Change the cursor back } }} //This function is called recursively until all nodes are loaded private void addTreeNode(XmlNode xmlNode, TreeNode treeNode) { XmlNode xNode; TreeNode tNode; XmlNodeList xNodeList; if (xmlNode.HasChildNodes) //The current node has children { xNodeList = xmlNode.ChildNodes; for (int x = 0; x <= xNodeList.Count - 1; x++) //Loop through the child nodes { xNode = xmlNode.ChildNodes[x]; treeNode.Nodes.Add(new TreeNode(xNode.Name)); tNode = treeNode.Nodes[x]; addTreeNode(xNode, tNode); } } else //No children, so add the outer xml (trimming off whitespace) treeNode.Text = xmlNode.OuterXml.Trim(); }

  • Arbitrary Form Processing with Drupal

    - by Aaron
    I am writing a module for my organization to cache XML feeds to static files to an arbitrary place on our webserver. I am new at Drupal development, and would like to know if I am approaching this the right way. Basically I: Expose a url via the menu hook, where a user can enter in a an output directory on the webserver and press the "dump" button and then have PHP go to drupal and get the feed xml. I don't need help with that functionality, because I actually have a prototype working in Python (outside of Drupal).. Provide a callback for the form where I can do my logic, using the form parameters. Here's the menu hook: function ncbi_cache_files_menu() { $items = array(); $items['admin/content/ncbi_cache_files'] = array( 'title' => 'NCBI Cache File Module', 'description' => 'Cache Guide static content to files', 'page callback' => 'drupal_get_form', 'page arguments' => array( 'ncbi_cache_files_show_submit'), 'access arguments' => array( 'administer site configuration' ), 'type' => MENU_NORMAL_ITEM, ); return $items; } I generate the form in: function ncbi_cache_files_show_submit() { $DEFAULT_OUT = 'http://myorg/foo'; $form[ 'ncbi_cache_files' ] = array( '#type' => 'textfield', '#title' => t('Output Directory'), '#description' => t('Where you want the static files to be dumped. This should be a directory that www has write access to, and should be accessible from the foo server'), '#default_value' => t( $DEFAULT_OUT ), '#size' => strlen( $DEFAULT_OUT ) + 5, ); $form['dump'] = array( '#type' => 'submit', '#value' => 'Dump', '#submit' => array( 'ncbi_cache_files_dump'), ); return system_settings_form( $form ); } Then the functionality is in the callback: function ncbi_cache_files_dump( $p, $q) { //dpm( get_defined_vars() ); $outdir = $p['ncbi_cache_files']['#post']['ncbi_cache_files']; drupal_set_message('outdir: ' . $outdir ); } The question: Is this a decent way of processing an arbitrary form in Drupal? I not really need to listen for any drupal hooks, because I am basically just doing some URL and file processing. What are those arguments that I'm getting in the callback ($q)? That's the form array I guess, with the post values? Is this the best way to get the form parameters to work on? Thanks for any advice.

  • How to stream semi-live audio over internet

    - by Thomas Tempelmann
    I want to write something like Skype, i.e. I have a constant audio stream on one computer and then recompress it in a format that's suitable for a latent internet connection, receive it on the other end and play it. Let's also assume that the internet connection is fairly modern and fast, i.e. DSL or alike, no slow connections over phone and such. The involved computers will also be rather modern (Dual Core Intel CPUs at 2GHz or more). I know how to handle the audio on the machines. What I don't know is how to transmit the audio in an efficient way. The challenges are: I'd like get good audio quality across the line. The stream should be received without drops. The stream may, however, be received with a little delay (a second delay is acceptable). I imagine that the transport software could first determine the average (and max) latency, then start the stream and tell the receiver to wait for that max latency before starting to play the audio. With that, if the latency doesn't get any higher, the entire stream will be playable on the other side without stutter or drops. If, due to unexpected IP latencies or blockages, the stream does get cut off, I want to be able to notice this so that I can take actions (e.g. abort the stream) and eventually start a new transmission. What are my options if I want do use ready-made software for the compression and tranmission? I have no intention to write my own audio compression engine, really. OTOH, I plan to sell the solution in a vertical market, meaning I can afford a few dollars of license fees per copy, but not $100s. I guess the simplest solution would be to just open a TCP stream, send a few packets back and forth to determine their running time (or even use UDP for that), then use the results as the guide for my max latency value, then simply fire the audio data in its raw form (uncompressed 16 bit stereo), along with a timing code over the TCP connection. The receiver reads the data and plays it with the pre-determined delay. That might just work with the type of fast connection I expect. I just wonder if there are better solutions to reach this goal, with better performance (lower latency) and less data (compressed). BTW, I first try to implement this on OS X, but might want to do it on Windows, too, if it proves successful.

  • Can't destroy record in many-to-many relationship

    - by Dmart
    I'm new to Rails, so I'm sure I've made a simple mistake. I've set up a many-to-many relationship between two models: User and Group. They're connected through the junction model GroupMember. Here are my models (removed irrelevant stuff): class User < ActiveRecord::Base has_many :group_members has_many :groups, :through => :group_members end class GroupMember < ActiveRecord::Base belongs_to :group belongs_to :user end class Group < ActiveRecord::Base has_many :group_members has_many :users, :through => :group_members end The table for GroupMembers contains additional information about the relationship, so I didn't use has_and_belongs_to_many (as per the Rails "Active Record Associations" guide). The problem I'm having is that I can't destroy a GroupMember. Here's the output from rails console: irb(main):006:0> m = GroupMember.new => #<GroupMember group_id: nil, user_id: nil, active: nil, created_at: nil, updated_at: nil> irb(main):007:0> m.group_id =1 => 1 irb(main):008:0> m.user_id = 16 => 16 irb(main):009:0> m.save => true irb(main):010:0> m.destroy NoMethodError: undefined method `eq' for nil:NilClass from /usr/local/lib/ruby/gems/1.8/gems/activesupport-3.0.4/lib/active_support/whiny_nil.rb:48:in `method_missing' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/persistence.rb:79:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/locking/optimistic.rb:110:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/callbacks.rb:260:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activesupport-3.0.4/lib/active_support/callbacks.rb:413:in `_run_destroy_callbacks' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/callbacks.rb:260:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:235:in `destroy' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:292:in `with_transaction_returning_status' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/connection_adapters/abstract/database_statements.rb:139:in `transaction' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:207:in `transaction' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:290:in `with_transaction_returning_status' from /usr/local/lib/ruby/gems/1.8/gems/activerecord-3.0.4/lib/active_record/transactions.rb:235:in `destroy' from (irb):10 This is driving me crazy, so any help would be greatly appreciated.

  • Sitecore E-Commerce Module - Discount/Promotional Codes

    - by Zachary Kniebel
    I am working on a project for which I must use Sitecore's E-Commerce Module (and Sitecore 6.5 rev. 120706 - aka 'Update 5') to create a web-store. One of the features that I am trying to implement is a generic promotional/discount code system - customer enters a code at checkout which grants a discount like 'free shipping', '20% off', etc. At the moment, I am looking for some guidance (a high-level solution, a few pseudo-ideas, some references to review, etc) as to how this can be accomplished. Summary: What I am looking for is a way to detect whether or not the user entered a promo code at a previous stage in the checkout line, and to determine what that promo code is, if they did. Progress Thus Far: I have thoroughly reviewed all of the Sitecore E-Commerce Services (SES) documentation, especially "SES Order Line Extension" documentation (which I believe will have to be modified/extended in order to accomplish this task). Additionally, I have thoroughly reviewed the Sitecore Community article Extending Sitecore E-Commerce - Pricing and believe that it may be a useful guide for applying a discount statically, but does not say much in the way of applying a discount dynamically. After reviewing these documents, I have come up with the following possible high-level solution to start from: I create a template to represent a promotional code, which holds all data relevant to the promotion (percent off, free shipping, code, etc). I then create another template (based on the Product Search Group template) that holds a link to an item within a global "Promotional Code" items folder. Next, I use the Product Search Group features of my new template to choose which products to apply the discount to. In the source code for the checkout I create a class that checks if a code has been entered and, if so, somehow carry it through the rest of the checkout process. This is where I get stuck. More Details: No using cookies No GET requests No changing/creating/deleting items in the Sitecore Database during the checkout process (e.g., no manipulation of fields of a discount item during checkout to signal that the discount has been applied) must stay within the scope of C# Last Notes: I will update this post with any more information that I find/progress that I make. I upgrade all answers that are relevant and detailed, thought-provoking, or otherwise useful to me and potentially useful to others, in addition to any high-level answers that serve as a feasible solution to this problem; even if your idea doesn't help me, if I think it will help someone else I will still upgrade it. Thanks, in advance, for all your help! :)

  • What variable dictates position of non-focused elements in the roundabout plugin?

    - by kristina childs
    Part of the problem here is that i'm not sure what the best language to use in order to find the solution. I search and searched so please forgive if this is already a thread somewhere. I'm using the roundabout plugin to cycle through 3 divs. Each div is 794px wide, which makes the roundabout-in-focus element 794 and the two not in focus 315.218px wide, positioned so half of each is hidden by the in-focus div. This is all well and good, however the total width of the display needs to stay within 1000px (ideally 980px, but i can fudge if need be.) Basically I want to make the non-focused divs be 3/4 hidden by the in-focus div but for the life of me can't figure out what variables i need to edit in order to do it. Unfortunately it's not one of the many easily-changed options like z-index and minScale. i tried minScale but it's clear this isn't going to work. the plugin outputs this code: <li class="roundabout-moveable-item" style="position: absolute; left: -57px; top: 205px; width: 319.982px; height: 149.513px; opacity: 0.7; z-index: 146; font-size: 5.6px;"> i need to find out what changes the left positioning so it's shifted closer to the center of the stage, like this: <li class="roundabout-moveable-item" style="position: absolute; left: 5px; top: 205px; width: 319.982px; height: 149.513px; opacity: 0.7; z-index: 146; font-size: 5.6px;"> i tried playing with the positioning functions of the plugin but all that did was shift everything in tandem left or right. any help is greatly appreciated. this site is going to be awesome once i figure out all this jquery stuff! here is a link to my .js file: http://avalon.eaw.com/scripts/jquery.roundabout2.js i've got an overflow:hidden on the to help guide the positioning of those no-focused items.

  • Creating a binary file from an IntelHex in C#

    - by Allek
    I'm trying to create a binary file from a intelHex file. Iside the intelHex file I have data and address to which I should write the data inside the binary file. IntelHex file looks like that :10010000214601360121470136007EFE09D2190140 :100110002146017EB7C20001FF5F16002148011988 :10012000194E79234623965778239EDA3F01B2CAA7 :100130003F0156702B5E712B722B732146013421C7 :00000001FF So I have 4 lines here with data since the last one tells us thats the end of file. Here is what I'm doing to create the file while (!streamReader.EndOfStream) { string temp = String.Empty; int address = 0; line = streamReader.ReadLine(); // Get address for each data address = Convert.ToInt32(line.Substring(3, 4), 16); // Get data from each line temp = line.Substring(7, 2); if (temp == "01") break; else { temp = line.Substring(9, line.Length - 11); string[] array = new string[(temp.Length / 2)]; int j = 0; for (int i = 0; i < array.Length; ++i) { array[i] = temp[j].ToString() + temp[j + 1].ToString(); j = j + 2; } temp = String.Empty; for (int i = 0; i < array.Length; ++i) { temp = temp + Convert.ToChar(Convert.ToInt32(array[i], 16)); } } binaryWriter.Seek(address, SeekOrigin.Begin); binaryWriter.Write(temp); binaryWriter.Flush(); } Console.WriteLine("Done...\nPress any key to exit..."); The problem here is, that data in binary file in some places is not equal to data from the intelHex file. Looks like there is some random data added to the file and I do not know from where. First time I saw that there is an additional data before the data from the intelHex file. For instance first data line starts with 21, but in binary file I have a number 12 before the 21. I do not know what is wrong here. Hope someone can help me or guide me where I can find some usefull informations about creating binary files in C#

  • validation functions in google apps script is not working properly

    - by chocka
    I create a i/p form in google site using Apps Script and i did the validation using the Apps Script coding. Validation functions available in Apps script is not satisfying all the possibility of checking the error. function validate(e) { var app = UiApp.getActiveApplication(); var flag=0; var text = app.getElementById('name'); var textrequired = app.getElementById('namerequired'); var number = app.getElementById('number'); var numberrequired = app.getElementById('numberrequired'); var email = app.getElementById('email'); var emailrequired = app.getElementById('emailrequired'); var submit = app.getElementById('submit_button'); var valid = app.createClientHandler() .validateNumber(number) .validateNotInteger(text) .validateEmail(email) .forTargets(submit).setEnabled(true) .forTargets(number,text,email).setStyleAttribute("color","black") .forTargets(numberrequired,textrequired,emailrequired).setText('*').setStyleAttribute("color", "red").setVisible(true); var invalidno = app.createClientHandler().validateNotNumber(number).validateMatches(number, '').forTargets(number).setStyleAttribute("color", "red").forTargets(submit).setEnabled(false).forTargets(numberrequired).setText('Please Enter a Valid No.').setStyleAttribute("color", "red").setVisible(true); var validno = app.createClientHandler().validateNumber(number).forTargets(number).setStyleAttribute("color","black").forTargets(numberrequired).setText('*').setStyleAttribute("color", "red").setVisible(true); var invalidText=app.createClientHandler().validateNumber(text).validateMatches(text, '').forTargets(text).setStyleAttribute("color", "red").forTargets(submit).setEnabled(false).forTargets(textrequired).setText('Please Enter a Valid Name.').setStyleAttribute("color", "red").setVisible(true); var validText=app.createClientHandler().validateNotNumber(text).forTargets(text).setStyleAttribute("color","black").forTargets(textrequired).setText('*').setStyleAttribute("color", "red").setVisible(true); var invalidemail=app.createClientHandler().validateNotEmail(email).validateMatches(email, '').forTargets(email).setStyleAttribute("color", "red").forTargets(submit).setEnabled(false).forTargets(emailrequired).setText('Please Enter a Valid Mail-Id.').setStyleAttribute("color", "red").setVisible(true); var validemail=app.createClientHandler().validateEmail(email).forTargets(email).setStyleAttribute("color","black").forTargets(emailrequired).setText('*').setStyleAttribute("color", "red").setVisible(true); number.addKeyPressHandler(invalidno).addKeyPressHandler(validno).addKeyPressHandler(valid).addKeyPressHandler(invalidText).addKeyPressHandler(invalidemail); text.addKeyPressHandler(invalidText).addKeyPressHandler(validText).addKeyPressHandler(valid).addKeyPressHandler(invalidno).addKeyPressHandler(invalidemail); email.addKeyPressHandler(invalidemail).addKeyPressHandler(validemail).addKeyPressHandler(valid).addKeyPressHandler(invalidno).addKeyPressHandler(invalidText); if (text == ''){flag = 1;} if (email == ''){flag = 1;} if (number == ''){flag = 1;} if(flag == 1){submit.setEnabled(false);} return app; } I just placed my Validation function using Apps Script. I don't know why its not satisfying all the possibilities of the validation. And also i have to do is to enable the submit button after all the fields satisfy the validation. After once it enabled, if i make any error in any field it will not get disable correctly. I wrote the coding correctly i think so. Please take a look at my validation function and give me some suggestion to make it possible. Please guide me, Thanks & Regards, chocka.

  • Execution plan issue requires reset on SQL Server 2005, how to determine cause?

    - by Tony Brandner
    We have a web application that delivers training to thousands of corporate students running on top of SQL Server 2005. Recently, we started seeing that a single specific query in the application went from 1 second to about 30 seconds in terms of execution time. The application started throwing timeouts in that area. Our first thought was that we may have incorrect indexes, so we reviewed the tables and indexes. However, similar queries elsewhere in the application also run quickly. Reviewing the indexes showed us that they were configured as expected. We were able to narrow it down to a single query, not a stored procedure. Running this query in SQL Studio also runs quickly. We tried running the application in a different server environment. So a different web server with the same query, parameters and database. The query still ran slow. The query is a fairly large one related to determining a student's current list of training. It includes joins and left joins on a dozen tables and subqueries. A few of the tables are fairly large (hundreds of thousands of rows) and some of the other tables are small lookup tables. The query uses a grouping clause and a few where conditions. A few of the tables are quite active and the contents change often but the volume of added rows doesn't seem extreme. These symptoms led us to consider the execution plan. First off, as soon as we reset the execution plan cache with the SQL command 'DBCC FREEPROCCACHE', the problem went away. Unfortunately, the problem started to reoccur within a few days. The problem has continued to plague us for awhile now. It's usually the same query, but we did appear to see the problem occur in another single query recently. It happens enough to be a nuisance. We're having a heck of a time trying to fix it since we can't reproduce it in any other environment other than production. I have downloaded the High Availability guide from Red Gate and I read up more on execution plans. I hope to run the profiler on the live server, but I'm a bit concerned about impact. I would like to ask - what is the best way to figure out what is triggering this problem? Has anyone else seen this same issue?
