  • ASP.NET and VB.NET OleDbConnection Problem

    - by Matt
    I'm working on an ASP.NET website where I am using an asp:repeater with paging done through a VB.NET code-behind file. I'm having trouble with the database connection though. As far as I can tell, the paging is working, but I can't get the data to be certain. The database is a Microsoft Access database. The function that should be accessing the database is: Dim pagedData As New PagedDataSource Sub Page_Load(ByVal obj As Object, ByVal e As EventArgs) doPaging() End Sub Function getTheData() As DataTable Dim DS As New DataSet() Dim strConnect As New OleDbConnection("Provider = Microsoft.Jet.OLEDB.4.0;Data Source=App_Data/ArtDatabase.mdb") Dim objOleDBAdapter As New OleDbDataAdapter("SELECT ArtID, FileLocation, Title, UserName, ArtDate FROM Art ORDER BY Art.ArtDate DESC", strConnect) objOleDBAdapter.Fill(DS, "Art") Return DS.Tables("Art").Copy End Function Sub doPaging() pagedData.DataSource = getTheData().DefaultView pagedData.AllowPaging = True pagedData.PageSize = 2 Try pagedData.CurrentPageIndex = Int32.Parse(Request.QueryString("Page")).ToString() Catch ex As Exception pagedData.CurrentPageIndex = 0 End Try btnPrev.Visible = (Not pagedData.IsFirstPage) btnNext.Visible = (Not pagedData.IsLastPage) pageNumber.Text = (pagedData.CurrentPageIndex + 1) & " of " & pagedData.PageCount ArtRepeater.DataSource = pagedData ArtRepeater.DataBind() End Sub The ASP.NET is: <asp:Repeater ID="ArtRepeater" runat="server"> <HeaderTemplate> <h2>Items in Selected Category:</h2> </HeaderTemplate> <ItemTemplate> <li> <asp:HyperLink runat="server" ID="HyperLink" NavigateUrl='<%# Eval("ArtID", "ArtPiece.aspx?ArtID={0}") %>'> <img src="<%# Eval("FileLocation") %>" alt="<%# DataBinder.Eval(Container.DataItem, "Title") %>t"/> <br /> <%# DataBinder.Eval(Container.DataItem, "Title") %> </asp:HyperLink> </li> </ItemTemplate> </asp:Repeater>

  • Rails, RSpec and Webrat: Expected output matches rendered output but still getting error in view spe

    - by Anthony Burns
    Hello all, I've just gotten started using BDD with RSpec/Cucumber/Webrat and Rails and I've run into some frustration trying to get my view spec to pass. First of all, I am running Ruby 1.9.1p129 with Rails 2.3.2, RSpec and RSpec-Rails 1.2.6, Cucumber 0.3.11, and Webrat 0.4.4. Here is the code relevant to my question config/routes.rb: map.b_posts 'backend/posts', :controller => 'backend/posts', :action => 'backend_index', :conditions => { :method => :get } map.connect 'backend/posts', :controller => 'backend/posts', :action => 'create', :conditions => { :method => :post } views/backend/posts/create.html.erb: <% form_tag do %> <% end %> *spec/views/backend/posts/create.html.erb_spec.rb:* describe "backend/posts/create.html.erb" do it "should render a form to create a post" do render "backend/posts/create.html.erb" response.should have_selector("form", :method => 'post', :action => b_posts_path) do |form| # Nothing here yet. end end end Here is the relevant part of the output when I run script/spec: 'backend/posts/create.html.erb should render a form to create a post' FAILED expected following output to contain a <form method='post' action='/backend/posts'/> tag: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <html><body><form action="/backend/posts" method="post"> </form></body></html> It would appear to me that what have_selector is looking for is exactly what the template generates, yet the example still fails. I am very much looking forward to seeing my error (because I have a feeling it is my error). Any help is much appreciated!

  • Poor Ruby on Rails performance when using nested :include

    - by Jeremiah Peschka
    I have three models that look something like this: class Bucket < ActiveRecord::Base has_many :entries end class Entry < ActiveRecord::Base belongs_to :submission belongs_to :bucket end class Submission < ActiveRecord::Base has_many :entries belongs_to :user end class User < ActiveRecord::Base has_many :submissions end When I retrieve a collection of entries doing something like: @entries = Entry.find(:all, :conditions => ['entries.bucket_id = ?', @bucket], :include => :submission) The performance is pretty quick although I get a large number of extra queries because the view uses the Submission.user object. However, if I add the user to the :include statement, the performance becomes terrible and it takes over a minute to return a total of 50 entries and submissions spread across 5 users. When I run the associated SQL commands, they complete in well under a second. @entries = Entry.find(:all, :conditions => ['entries.bucket_id = ?', @bucket], :include => {:submission => :user}) Why would this second command have such terrible performance compared to the first?

  • vlad the deployer: why do I need a scm folder?

    - by egarcia
    I'm learning to use vlad the deployer and I've got a question. Since I'm still learning I don't know what is pertinent to the question and what isn't, so please bear with me if I'm a little verbose. I've got 2 environments for a new application (test and production) besides my development machine. I've figured out this way to do the initial setup in my vlad.rake: namespace :test task :set set :domain, 'test.myserver.com' end end namespace :production task :set set :domain, 'www.myserver.com' end end This way I can have environment-specific stuff inside the namespaces, and still have shared tasks. For example, this would be the initial setup for test: rake vlad:test:set vlad:setup vlad:update This creates the following folders on my test server: releases/ scm/ shared/ current -> symlink to last release (inside the releases folder) My question is: what's the point of the scm folder? Every time I do vlad:update, the following happens: svn checkout on the scm/ folder above svn export on the /releases/{date} folder update current symlink So scm is a copy of my repository... but then there's an "export" copy of the repository on /releases/{date}. And that is the one used by the application... scm doesn't seem to be used by anyone? Wouldn't I be just fine without the scm folder?

  • Rails 3.2 Ajax Update Div when Text Field Populated

    - by ctilley79
    In the end I would like a text field that passes a client_id to the partial. I would like to do this asynchronously so the shipment_products partial would dynamically change when the textfield value was updated. What is the best way to do this? In index.html.erb <!-- Text Field Here--> <div id="available_products"> <%= render "shipment_products" %> </div> In _shipment_products.html.erb <div id="shipment_products_container"> <h3>Assign Products to Ship<\h3> <ul class="shipment_products" id="shipment_products"> <% Product.by_client(client_id).each do |product|%> <!-- TextField value passed here --> <%= content_tag_for :li, product, :value => product.id do %> <%= hidden_field_tag("shipment[product_ids][]", product.id) %> <%= product.product_name %> <% end %> <% end %> <\ul> </div> This is similar to what I want in the end.

  • Metamorphs Messing Up CSS in Ember.js Views

    - by Austin Fatheree
    I'm using Ember.js / handlebars to loop through a collection and spit out some items that I'd like bootstrap to handle nice and responsive like. Here is the issue: The bootstrap-responsive css has some declrations in it like: .row-fluid > [class*="span"]:first-child { margin-left: 0; } and .row-fluid:before, .row-fluid:after { display: table; content: ""; } These rules seem to target the first children. When I loop through my collection in handlebars I end up with a bunch of metamorph code around my items: <div class="row-fluid"> {{#each restaurantList}} {{view GS.vHomePageRestList content=this class="span6"}} {{/each}} </div> Here is what is produced: <div class="row-fluid"> <script id="metamorph-9-start" type="text/x-placeholder"></script> <script id="metamorph-104-start" type="text/x-placeholder"></script> <div id="ember2527" class="ember-view span6"> My View </div> <script id="metamorph-104-end" type="text/x-placeholder"></script> <script id="metamorph-105-start" type="text/x-placeholder"></script> <div id="ember2574" class="ember-view span6"> My View 2 </div> <script id="metamorph-105-end" type="text/x-placeholder"></script> <script id="metamorph-9-end" type="text/x-placeholder"></script> </div> So my question is this: 1. How can I tell css to ignore script tags? or 2. How can I edit the css bindings so that they skip over script tags when selecting the first or first child? or 3. How can I structure this so that Ember uses fewer/no metamorph tags? Here is a fiddle: http://jsfiddle.net/skilesare/SgwsJ/

  • Accessing Attributes in a Many-to-Many

    - by tshauck
    Hi, I have a rails app and I'd like to be able to do something like task.labels.first.label_name to get the label name of a task. However, I get an undefined method label_name. I did a t = Task.first; t.labels.first.label_name in the console, and that worked so I'm not sure what's going on. Here's the models then the locations of the error: class Categorization < ActiveRecord::Base belongs_to :label belongs_to :task end class Label < ActiveRecord::Base attr_accessible :label_name has_many :categorizations has_many :tasks, :through => :categorizations end class Task < ActiveRecord::Base attr_accessible :task has_many :categorizations has_many :labels, :through => :categorizations end The error is in the index <% for task in @tasks %> <tr> <td><%= task.task %></td> <td><%= task.labels.first.label_name %></td> <td><%= link_to "Show", task %></td> <td><%= link_to "Edit", edit_task_path(task) %></td> <td><%= link_to "Destroy", task, :confirm => 'Are you sure?', :method => :delete %></td> </tr> <% end %

  • Big sinatra problems

    - by Joel M.
    Hi, So I'm having huge trouble with sinatra. Here's what I have: require 'dm-core' DataMapper.setup(:default, ENV['DATABASE_URL'] || 'sqlite3://my.db') class Something include DataMapper::Resource property :id, Serial property :thing, Text property :run_in, Integer property :added_at, DateTime property :to, String def schedule cronify(self.thing+" to "+self.to, "http://url"+self.id.to_s, self.run_in) end def notify text(self.thing, self.to) end end Something.auto_upgrade! The cronify method works. I tested it in irb. Also, the schedule instance method works, I tested it in the console. However, it doesn't work in the route, even though it works in the console. post '/add' do @something = Something.create(blah) #this works fine @something.schedule #this works fine in the console; not in the route. end I've tried everything, from @something.create(blah).schedule (which also works fine in the console, but not in the route), to defining the method cronify inside the sinatra helpers, and even calling cronify directly on the route. Nothing works on the route. What am I doing wrong?

  • Converting plain text in SQL to hyperlink in Access

    - by manemawanna
    Hello, I've just started a new job my first since leaving University and as part of this my first task is to convert a wholly Access 2003 database to an Access front-end, SQL back-end. The Access database consists of a series of front end forms to add or review staff data, as part of this there is hyperlinks pointing to a photograph of the employee and there CV located on a shared drive. These were saved as hyperlinks within the Access DB. I have since converted the data in the Access DB to SQL and stored it in a database for me to test on, now as part of the data conversion the photo and CV locations were converted to nvarchar from hyperlink. I've done this using SSMA. My issue now is that I need to have these text links displayed and working as hyperlinks on the front end hidden behind the words "Photo" and "CV", but am unsure as to how to go about this, as in the past I've only ever used SQL and not Access. Any help or suggestions would be appreciated and if I've not been clear in any areas please feel free to ask questions and I'll try to clear anything up for you.

  • How do I expose the columns collection of GridView control that is inside a user control

    - by Christopher Edwards
    See edit. I want to be able to do this in the aspx that consumes the user control. <uc:MyControl ID="MyGrid" runat="server"> <asp:BoundField DataField="FirstColumn" HeaderText="FirstColumn" /> <asp:BoundField DataField="SecondColumn" HeaderText="SecondColumn" /> </uc> I have this code (which doesn't work). Any ideas what I am doing wrong? VB Partial Public Class MyControl Inherits UserControl <System.Web.UI.IDReferenceProperty(GetType(DataControlFieldCollection))> _ Public Property Columns() As DataControlFieldCollection Get Return MyGridView.Columns End Get Set(ByVal value As DataControlFieldCollection) ' The Columns collection of the GridView is ReadOnly, so I rebuild it MyGridView.Columns.Clear() For Each c As DataControlField In value MyGridView.Columns.Add(c) Next End Set End Property ... End Class C# public partial class MyControl : UserControl {         [System.Web.UI.IDReferenceProperty(typeof(DataControlFieldCollection))]     public DataControlFieldCollection Columns {         get { return MyGridView.Columns; }         set {             MyGridView.Columns.Clear();             foreach (DataControlField c in value) {                 MyGridView.Columns.Add(c);             }         }     } ... } EDIT: Actually it does work, but auto complete does not work between the uc:MyControl opening and closing tags and I get compiler warnings:- Content is not allowed between the opening and closing tags for element 'MyControl'. Validation (XHTML 1.0 Transitional): Element 'columns' is not supported. Element 'BoundField' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing. So I guess I need to use some sort of directive to tell the complier to expect content between the tags. Any ideas?

  • VB.net Saving an MetaFile / EMF as a bitmap ( .tiff)

    - by pehaada
    Currently I have a third party control that generates a Metafile. I can save the .wmf file to disk with out issue. The problem is how do I render the Metafile as a Tiff file. Currently I have the following code to get my metafile and save it. Dim mf As Metafile = page.GetImage(TXTextControl.Page.PageContent.All) Dim enhMetafileHandle As IntPtr = mf.GetHenhmetafile() Dim h As IntPtr Dim bufferSize As UInteger = GetEnhMetaFileBits(enhMetafileHandle, 0, h) Dim buffer(CInt(bufferSize)) As Byte GetEnhMetaFileBits(enhMetafileHandle, bufferSize, buffer) Dim msMetafileStream As New MemoryStream msMetafileStream.Write(buffer, 0, CInt(bufferSize)) Dim baMetafileData() As Byte baMetafileData = msMetafileStream.ToArray Dim g As Graphics = Graphics.FromImage(mf) mf.Dispose() File.WriteAllBytes("c:\a.wmf", baMetafileData) end sub _ Public Shared Function GetEnhMetaFileBits( ByVal hEMF As System.IntPtr, ByVal nSize As UInteger, ByVal lpData As IntPtr) As UInteger End Function <System.Runtime.InteropServices.DllImportAttribute("gdi32.dll", EntryPoint:="GetEnhMetaFileBits")> _ Public Shared Function GetEnhMetaFileBits(<System.Runtime.InteropServices.InAttribute()> ByVal hEMF As System.IntPtr, ByVal nSize As UInteger, ByVal lpData() As Byte) As UInteger End Function I've tried all sort of IMAGE and Graphic calls and just can't save the meta file as a .tiff. Any suggestions would be great. I even tried to create a new bitmap and draw the metafile onto it. I always end up with a GDI exception being thrown.

  • Authlogic Current User Question - hiding admin links...

    I think I am missing something while using the Authlogic gem w/ Rails. To set the stage I have multiple users and each user can create posts and comments. Upon the display of a post or comment I would like to give the user who created them the option to edit or destroy. I am successfully using the following code to hide and show elements based on if a user is logged in or not but can't seem to find out how to only show these links to the actual user who created them...not any user that is logged in. <% if current_user %> <%= link_to 'Edit', edit_question_path(question) %> | <%= link_to 'Destroy', question, :confirm => 'Are you sure?', :method => :delete %> <% else %> <p>nothing to see here</p> <% end %> Here is the def of current_user located in the application controller in case I need to change something here. class ApplicationController < ActionController::Base helper :all # include all helpers, all the time protect_from_forgery # See ActionController::RequestForgeryProtection for details# helper_method :current_user private def current_user_session return @current_user_session if defined?(@current_user_session) @current_user_session = UserSession.find end def current_user return @current_user if defined?(@current_user) @current_user = current_user_session && current_user_session.record end end

  • Credit card system implementation?

    - by Mark
    My site is going to have a credit system that basically works a lot like a credit card. Each user has an unlimited credit limit, but at the end of each week, they have to pay it off. For example, a user might make several purchases between March 1st and 7th, and then at the end of March 7th, they would be emailed an invoice that lists all their purchases during the week and a total that is due by the 14th. If they don't pay it off, their account is simply deactivated until they do. I'm just trying to wrap my head around how to implement this. I have a list of all their purchases, that's not a problem, but I'm just trying to figure out what to do with it. On the end of the 7th day, I could set up a cronjob to generate an invoice, which would basically have an id, and due date, and then I would need another many-to-many table to link all the purchases to the invoice. Then when a user adds money to their account, I guess it's applied against their current outstanding invoice? And what if they don't pay off their invoice by the time a new invoice rolls around, so now they have 2 outstanding ones, how do I know which to apply it against? Or do I make the cronjob check for any previous outstanding invoices, cancel them, and add a new item to the new invoice as "balance forward (+interest)"? How would you apply the money against an invoice? Would each payment have to be linked to an invoice, or could I just deposit it to their account credit, and then somehow figure out whats been paid and what hasn't? What if they pay in advance, before their invoice has been generated? Do I deduct it from their credit from the invoice upon generation, or at the end of the week when its due? There are so many ways to do this... Can anyone describe what approach they would take?

  • fluent nHibernate mapping of subclassed structure

    - by Codezy
    I have a workflow class that has a collection of phases, each phase has a collection of tasks. You can design a workflow that will be used by many engagements. When used in engagement I want to be able to add properties to each class (workflow, phase, and task). For example a task in the designer does not have people assigned, but a task in an engagement would need extra properties like who is assigned to it. I have tried many different approaches using subclasses or interfaces but I just can't get it to map the way I want. Currently I have the engagement level versions as subclasses, but I can't get Engagement phases to map to engagement workflows. Public Class WorkflowMapping Inherits ClassMap(Of Workflow) Sub New() Id(Function(x As Workflow) x.Id).Column("Workflow_Id").GeneratedBy.Identity() Map(Function(x As Workflow) x.Description) Map(Function(x As Workflow) x.Generation) Map(Function(x As Workflow) x.IsActive) HasMany(Function(x As Workflow) x.Phases).Cascade.All() End Sub End Class Public Class EngagementWorkflowMapping Inherits SubclassMap(Of EngagementWorkflow) Sub New() Map(Function(x As EngagementWorkflow) x.ClientNo) Map(Function(x As EngagementWorkflow) x.EngagementNo) End Sub End Class How would you approach mapping this in fluent (or hbm) so that you could load just the workflow base class when designing the flow, or the engagement subclass versions of each when being used by an engagement?

  • how to extend a protocol for a delegate in objective C, then subclass an object to require a conform

    - by fess .
    I want to subclass UITextView, and send a new message to the delegate. So, I want to extend the delegate protocol, What's the correct way to do this? I started out with this: interface: #import <Foundation/Foundation.h> @class MySubClass; @protocol MySubClassDelegate <UITextViewDelegate> - (void) MySubClassMessage: (MySubClass *) subclass; @end @interface MySubClass : UITextView { } @end implementation: #import "MySubClass.h" @implementation MySubClass - (void) SomeMethod; { if ([self.delegate respondsToSelector: @selector (MySubClassMessage:)]) { [self.delegate MySubClassMessage: self]; } } @end however with that I get the warning: '-MySubClassMessage:' not found in protocol(s). I had one way working where I created my own ivar to store the delegate, then also stored the delegate using [super setDelegate] but that seemed wrong. perhaps it's not. I know I can just pass id's around and get by, but My goal is to make sure that the compiler checks that any delegate supplied to MySubClass conforms to MySubClassDelegate protocol. To further clairfy: @interface MySubClassTester : NSObject { } @implementation MySubClassTester - (void) one { MySubClass *subclass = [[MySubClass alloc] init]; subclass.delegate = self; } @end will produce the warning: class 'MySubClassTester' does not implement the 'UITextViewDelegate' protocol I want it to produce the warning about not implementing 'MySubClassDelegate' protocol instead. Thanks, a bunch. (thanks brad)

  • AContext.data can be nil?

    In this code, as you see on Connect, AContext.Data is filled with something TmyTThreadList = class(TThreadList) id: integer; end; var unique_id:integer; procedure TfrmTestIdTCPServer.IdTCPServerConnect(AContext: TIdContext); begin CS.Enter; try inc(unique_id); finally CS.Leave; end; AContext.Data := myTThreadList.Create; list := myTThreadList(AContext.Data).LockList; try myTThreadList(AContext.Data).id := my_unique_id; list.Add(myTThreadList(AContext.Data)); finally myTThreadList(AContext.Data).UnlockList; end; end; then on disconnect, coder is checking here for Acontext.Data < nil procedure TfrmTestIdTCPServer.IdTCPServerDisconnect(AContext: TIdContext); var begin if AContext.Data <> nil then begin The question is, why he is checking for nil ? Thanks. EDIT: I'm asking this, because when I do the same, onExecute I access AContext.Data , and sometimes (when in same time is connecting many clients) AContext.Data is empty, access violation appears.

Is there somethink wrong with the code or must I do it different in Lazarus/Freepascal? Thanks.

    Let's say I have 2 interfaces defined like so: public interface ISkuItem { public string SKU { get; set; } } public interface ICartItem : ISkuItem { public int Quantity { get; set; } public bool IsDiscountable { get; set; } } When I go to implement the interface in C#, VS produces the following templated code: public class CartItem : ICartItem { #region ICartItem Members public int Quantity { get {...} set {...} } public bool IsDiscountable { get {...} set {...} } #endregion #region ISkuItem Members public string SKU { get {...} set {...} } #endregion } In VB.NET, the same class is built out like so: Public Class CartItem Implements ICartItem Public Property IsDiscountable As Boolean Implements ICartItem.IsDiscountable 'GET SET' End Property Public Property Quantity As Integer Implements ICartItem.Quantity 'GET SET' End Property Public Property SKU As String Implements ISkuItem.SKU 'GET SET' End Property End Class VB.NET explicitly requires you to add Implements IInterfaceName.PropertyName after each property that gets implemented whereas C# simply uses regions to indicate which properties and methods belong to the interface. Interestingly in VB.NET, on the SKU property, I can specify either Implements ISkuItem.SKU or Implements ICartItem.SKU. Although the template built by VS defaults to ISkuItem, I can also specify ICartItem if I want. Oddly, because C# only uses regions to block out inherited properties, it seems that I can't explicitly specify the implementing interface of SKU in C# like I can in VB.NET. My question is: Is there any importance behind being able to specify one interface or another to implement properites in VB.NET, and if so, is there a way to mimic this functionality in C#?

  • Delete all rows that do not have the value: Criteria 1 or Criteria 2 or Criteria 3 in Column D --> Using VBA Macro for excel

    - by JDS
    I am new to Macro's/VBA and cannot seem to figure out how to do this action for multiple criteria. I am trying to Delete all rows that do not have the value: Identify Fail or Identify Success in Column D. I write the following code and it works for one criteria "Identify Fail": '***********************************************' Sub DeleteRows() 'Action 1 --> Delete all Rows without Identify Fail in column D' Application.ScreenUpdating = False For i = Range("D" & Rows.Count).End(xlUp).Row To 1 Step -1 If Range("D" & i).Value <> "Identify Fail" Then Rows(i).Delete shift:=xlUp Next i Application.ScreenUpdating = True End Sub '***********************************************' Once I try to add 'OR' with another criteria it does not work: '***********************************************' Sub DeleteRows() 'Action 1 --> Delete all Rows without Identify Fail in column D' Application.ScreenUpdating = False For i = Range("D" & Rows.Count).End(xlUp).Row To 1 Step -1 If Range("D" & i).Value <> "Identify Fail" Or "Identify Success" Then Rows(i).Deleteshift:=xlUp Next i Application.ScreenUpdating = True End Sub '***********************************************' Any suggestions would be appreciated as I have been scouring this website and have not found an efficient code that will do the trick.

  • not a valid AllXsd value

    - by jun
    I got this from a Soap client request: Exception: SoapFault exception: [soap:Client] Server was unable to read request. --- There is an error in XML document (2, 273). --- The string '2010-5-24' is not a valid AllXsd value. in /path/filinet.php:21 Stack trace: #0 [internal function]: SoapClient-__call('SubIdDetailsByO...', Array) #1 /path/filinet.php(21): SoapClient-SubIdDetailsByOfferId(Array) #2 {main} Seems like I am sending an incorrect value, how do I format my value in an AllXsd in php? Here is my code: <?php $start = isset($_GET['start']) ? $_GET['start'] : date("Y-m-d"); $end = isset($_GET['end']) ? $_GET['end'] : date("Y-m-d"); //define parameter array $param = array('userName'=>'user', 'password'=>'pass', 'startDate' => $start, 'endDate' => $end, 'promotionId' => ''); //Get wsdl path $serverPath = "https://webservices.filinet.com/affiliate/reports.asmx?WSDL"; //Declare Soap client $client = new SoapClient($serverPath); try { //make the call $result = $client->SubIdDetailsByOfferId($param); //If error found display error if(isset($fault)) { echo "Error: ". $fault; } //If no error display response else { //Used to display raw XML in the Web Browser header("Content-Type: text/xml;"); //SubIdDetailsResult = XML results echo $result->SubIdDetailsByOfferIdResult; } } catch(SoapFault $ex) { echo "<b>Exception:</b> ". $ex; } unset($client); ?>

  • Implementing the tree with reference to the root for each leaf

    - by AntonAL
    Hi, i implementing a products catalog, that looks, like this: group 1 subgroup 1 subgroup 2 item 1 item 2 ... item n ... subgroup n group 2 subgroup 1 ... subgroup n group 3 ... group n The Models: class CatalogGroup < ActiveRecord::Base has_many: catalog_items has_many :catalog_items_all, :class_name => "CatalogItem", :foreign_key => "catalog_root_group_id" end class CatalogItem < ActiveRecord::Base belongs_to :catalog_group belongs_to :catalog_root_group, :class_name => "CatalogGroup" end Migrations: class CreateCatalogItems < ActiveRecord::Migration def self.up create_table :catalog_items do |t| t.integer :catalog_group_id t.integer :catalog_root_group_id t.string :code t.timestamps end end For convenience, i referenced each CatalogItem to it's top-most CatalogGroup and named this association "catalog_root_group". This will give us the simple implementation of search request, like "show me all items in group 1". We will have a deal only with CatalogModel.catalog_root_group The problem is - this association does't work. I always get "catalog_root_group" equals to nil Also, i have tried to overcome the using of reference to root group ("catalog_root_group"), but i cannot construct appropriate search request in ruby ... Do you know, how to do it ?

  • calloc v/s malloc and time efficiency

    - by yCalleecharan
    Hi, I've read with interest the post "c difference between malloc and calloc". I'm using malloc in my code and would like to know what difference I'll have using calloc instead. My present (pseudo)code with malloc: Scenario 1 int main() { allocate large arrays with malloc INITIALIZE ALL ARRAY ELEMENTS TO ZERO for loop //say 1000 times do something and write results to arrays end for loop FREE ARRAYS with free command } //end main If I use calloc instead of malloc, then I'll have: Scenario2 int main() { for loop //say 1000 times ALLOCATION OF ARRAYS WITH CALLOC do something and write results to arrays FREE ARRAYS with free command end for loop } //end main I have three questions: Which of the scenarios is more efficient if the arrays are very large? Which of the scenarios will be more time efficient if the arrays are very large? In both scenarios,I'm just writing to arrays in the sense that for any given iteration in the for loop, I'm writing each array sequentially from the first element to the last element. The important question: If I'm using malloc as in scenario 1, then is it necessary that I initialize the elements to zero? Say with malloc I have array z = [garbage1, garbage2, garbage 3]. For each iteration, I'm writing elements sequentially i.e. in the first iteration I get z =[some_result, garbage2, garbage3], in the second iteration I get in the first iteration I get z =[some_result, another_result, garbage3] and so on, then do I need specifically to initialize my arrays after malloc?
