• WCF configuration file: why do we need clientBaseAddress in Binding section?

  - by Captain Comic

  Hi, There are three sections in WCF configuration for service client: Look at bindings = clientBaseAddress Why do we need to specify callback address? Is this field required? Why .NET is unable to determine the address of client? Does it mean that i can specify callback service that is located on some other machine? <configuration> <system.serviceModel> <client> <endpoint address= </client> <bindings> <wsDualHttpBinding> <binding name= clientBaseAddress= maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" </binding> </wsDualHttpBinding> </bindings> <behaviors> <endpointBehaviors> <behavior name=> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel>

• How to access attributes using Nokogiri

  - by Liz

  I have a simple task of accessing the values of some attributes. Below is a simple script that uses Nokogiri::XML::Builder to create a simple xml doc. require 'nokogiri' builder = Nokogiri::XML::Builder.new(:encoding => 'UTF-8') do |xml| xml.Placement(:messageId => "392847-039820-938777", :system => "MOD", :version => "2.0") { xml.objects { xml.object(:myattribute => "99", :anotherattrib => "333") xml.nextobject_ '9387toot' xml.Entertainment "Last Man Standing" } } end puts builder.to_xml puts builder.root.attributes["messageId"] The results are below: <?xml version="1.0" encoding="UTF-8"?> <Placement messageId="392847-039820-938777" version="2.0" system="MOD"> <objects> <object anotherattrib="333" myattribute="99"/> <nextobject>9387toot</nextobject> <Entertainment>Last Man Standing</Entertainment> </objects> </Placement> C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/document.rb:178:in `add_child': Document already has a root node (RuntimeError) from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/node.rb:455:in `parent=' from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/builder.rb:358:in `insert' from C:/Ruby/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-x86-mingw32/lib/nokogiri/xml/builder.rb:350:in `method_missing' from C:/Documents and Settings/etrojan/workspace/Lads/tryXPATH2.rb:15 The xml that is generated looks fine. However, my attempts to access attributes cause an error to be generated, "Document already has a root node". I don't understand why a puts statement would cause this error. Any suggestions would be greatly appreciated.

• Zend Cache is not retrieving cache items after some period of time

  - by Phil

  Hi, I am using Zend Cache with page caching but it seems to miss the cache after a period of time. For a while it is OK, but I come back tomorrow and hit the page, it doesn't fetch the contents from the cache. why? $frontendOptions = array( 'content_type_memorization' => true, // This remembers the headers, needed for images 'lifetime' => NULL, // cache lifetime forever 'automatic_serialization' => true, 'automatic_cleaning_factor' => 0 ); $myPageCache = new Zend_Cache_Frontend_Page(array( 'debug_header' => false, 'automatic_cleaning_factor'=>0, 'content_type_memorization' => true, 'default_options' => array( 'cache' => true, 'cache_with_get_variables' => true, 'cache_with_post_variables' => true, 'cache_with_session_variables' => true, 'cache_with_cookie_variables' => true ))); $backendOptions = array('cache_dir' => '.' . DIRECTORY_SEPARATOR . 'cache' . DIRECTORY_SEPARATOR); $cache = Zend_Cache::factory($myPageCache, 'File', $frontendOptions, $backendOptions); $cacheKey = hash('md5', "cache_" . $cachePath); // cachePath is the key I use for the cache if(!$cache->start($cacheKey)) { I output html here $cache->end(); }

• How does FallbackValue work with a MultiBiding?

  - by Will

  I ask because it doesn't seem to work. Assume we're binding to the following object: public class HurrDurr { public string Hurr {get{return null;}} public string Durr {get{return null;}} } Well, it would appear that if we used a MultiBinding against this the fallback value would be shown, right? <TextBlock> <TextBlock.Text> <MultiBinding StringFormat="{}{0} to the {1}" FallbackValue="Not set! It works as expected!)"> <Binding Path="Hurr"/> <Binding Path="Durr"/> </MultiBinding> </TextBlock.Text> </TextBlock> However the result is, in fact, " to the ". Even forcing the bindings to return DependencyProperty.UnsetValue doesn't work: <TextBlock xmnlns:base="clr-namespace:System.Windows;assembly=WindowsBase"> <TextBlock.Text> <MultiBinding StringFormat="{}{0} to the {1}" FallbackValue="Not set! It works as expected!)"> <Binding Path="Hurr" FallbackValue="{x:Static base:DependencyProperty.UnsetValue}" /> <Binding Path="Durr" FallbackValue="{x:Static base:DependencyProperty.UnsetValue}" /> </MultiBinding> </TextBlock.Text> </TextBlock> Tried the same with TargetNullValue, which was also a bust all the way around. So it appears that MultiBinding will never ever use FallbackValue. Is this true, or am I missing something?

• ASP:NET :Problem in DoNut Caching

  - by Shyju

  I have an ASP.NET page where i am trying to do some output caching.But ran into a problem. My ASPX page has <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="MYProject._Default" %> <%@ OutputCache Duration="600" VaryByParam="None" %> <%@ Register TagPrefix="MYProjectUC" TagName="PageHeader" Src="~/Lib/UserControls/PageHeader.ascx" %> <%@ Register TagPrefix="MYProjectUC" TagName="PageFooter" Src="~/Lib/UserControls/PageFooter.ascx" %> and i have used the User control called "PageHeader" in the aspx page. In PageHeader.ascx, i have an asp.net substitution control, where i want to show some links based on the logged in user. <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="PageHeader.ascx.cs" Inherits="MyProject.Lib.UserControls.PageHeader1" %> <div class="headerRow"> <div class="headerLogo"> <a href="Default.aspx"><img src="Lib/Images/header.gif" alt=""></a> </div> <div id="divHeaderMenu" runat="server"> <asp:Substitution ID="subLinks" runat="server" MethodName="GetUserProfileHeaderLinks" /> </div> </div><!--headerRow--> In my ascx.cs file,i have a static method which will return a string based on whether the used logged in or not using session public static string GetUserProfileHeaderLinks(HttpContext context) { string strHeaderLinks = string.Empty; // check session and return string return strHeaderLinks; } But Still the page shows the same content for both logged in user and Guest user. My objective is to to have the Page being cached except the content inside the substitution control. Any idea how to achieve this ? Thanks in advance

• jquery slide toggle divs without creating multiple classes, functions, etc... ui accordion

  - by SPE

  Greetings, based on the jquery ui accordion I'm using, I have added a slide toggle to my accordion list items. so what happens is I click on an li and a div slides down underneath to reveal more content. The issue I'm having is that I find myself having to create multiple id's to reference the slidetoggle. example of the div id css: #panel, #panel2, #panel3, #panel4, etc.... the Is there a way I can use the slide toggle without having to adding another number so it will slide? I have 50 list items I'm using: Here's a sample of the js (as you can see where I'm going with this): $(".btn-slide").click(function(){ $("#panel").slideToggle("slow"); $(this).toggleClass("active"); return false; }); $(".btn-slide2").click(function(){ $("#panel2").slideToggle("slow"); $(this).toggleClass("active"); return false; }); sample html: <li><div class="slide"><a href="#" class="btn-slide">One</a></div><div id="panel"></div></li> <li><div class="slide"><a href="#" class="btn-slide2">Two</a></div><div id="panel2"></div></li>

• Trigger for ComboBox in Silverlight

  - by Budda

  Is there any possibility to display selected item of the ComboBox (after popup closing) in a way that is different from its displaying in DropDown List (There are players number and name in the dropdown list, but after list closing I want to see only its number). How can I change a background for the player with some Flag? As far as I know, all of that can be done with triggers, but are they supported in Silverlight 4, VS2010, Silverlight Toolkit 4? In my case the following code <ComboBox ItemsSource="{Binding PlayersAll}" SelectedItem="{Binding Path=SelectedPlayer, Mode=TwoWay}" > <ComboBox.ItemTemplate> <DataTemplate> <ToolkitControls:WrapPanel Orientation="Horizontal"> <TextBlock Text="{Binding TeamNumber}"/> <TextBlock Text=" - "/> <TextBlock Text="{Binding ShortName}"/> </ToolkitControls:WrapPanel> <DataTemplate.Triggers> <Trigger Property="HasError" Value="True"> <Setter Property="Background" TargetName="FlagSet" Value="Red"/> </Trigger> </DataTemplate.Triggers> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> gives an error: The property 'Triggers' does not exist on the type 'DataTemplate' in the XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation' what is wrong here? Here are my namespaces: xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" xmlns:ToolkitControls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Toolkit"

• Add a background color to text, but with space blank space between lines of paragraph

  - by Chris

  Hi, I was wondering if something was possible to do in CSS. Basically i want to recreate the text on the RHS of the image using html/css, but currently I'm getting the LHS of the image. The HTML: <div id="banner"> <div id="text"> <p>This is an example of what I have</p> </div> </div> The CSS: div#banner { background: green; width:300px; height:300px;} div#text { margin: 20px auto; } div#text p { background:#fff; padding: 5px; margin: 5px; font-size: 2em; } Now I realise that this can be done already either by: Using an image Using separate p tags (By Point 2 I mean: <div id="banner"> <div id="text"> <p>This is an</p> <p>example of</p> <p>what I have</p> </div> </div> ) But what I would really like to know is if it's actually possible to do what is on the RHS of the image, using only css and a single p tag?

• jQuery AJAX call not working in Webkit

  - by Brian

  I've run into a strange issue with Webkit based browsers (both Safari and Chrome - I'm testing on a Mac) and I am not sure what is causing it. Here's a small script I've created that replicates the issue: <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" language="javascript"> function doRequest() { document.test.submit(); $.ajax({ type: "GET", cache: false, url: 'ajax.php?tmp=1', success: doSuccess }); } function doSuccess(t_data,t_status,req) { alert('Data is: '+ t_data +', XMLHTTPRequest status is: '+ req.status); } </script> </head> <body> <form name="test" method="post" action="ajax.html" enctype="multipart/form-data"> <input type="file" name="file_1"> <br><input type="button" value="upload" onclick="doRequest();"> </form> </body> </html> ajax.php is: <?php echo $_REQUEST['tmp']; ?> This works as is on Firefox, but the XMLHTTPRequest status is always "0" on both Safari and Chrome. If I remove this line: document.test.submit(); then it works, but of course the form is not submitted. I've tried changing the form submit button from "button" to "submit", but that also prevents it from working on Safari or Chrome. What I am trying to accomplish is: submit the form call another script to get status on the file being uploaded via the form (it's for a small upload progress meter). Any help is really appreciated - I'm hopeful it is just a quirk I'm not familiar with. Thanks! Brian

• Why doesn't jquery .load() load a text file from an external website?

  - by Edward Tanguay

  In the example below, when I click the button, it says "Load was performed" but no text is shown. I have a clientaccesspolicy.xml in the root directory and am able to asynchronously load the same file from silverlight. So I would think I should be able to access from AJAX as well. What do I have to change so that the text of the file http://www.tanguay.info/knowsite/data.txt is properly displayed in the #content element? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1.3.2"); google.setOnLoadCallback(function() { $('#loadButton').click(loadDataFromExernalWebsite); }); function loadDataFromExernalWebsite() { $('#content').load('http://www.tanguay.info/knowsite/data.txt', function() { alert('Load was performed.'); }); } </script> </head> <body> <p>Click the button to load content:</p> <p id="content"></p> <input id="loadButton" type="button" value="load content"/> </body> </html>

• Conditionally install feature not working in Wix

  Hi, I have a setup which I need to support on IIS6 and IIS7.

I have also tried putting the condition in the component and that didnt work either. Is there something wrong with my usage?

  - by MakkyNZ

  Hi The javascript generated by the asp.net SciptManager control seems to have a bug and cant handle hidden UpdatePanels. A javascript error is thrown when a control within one updated panel tries to make another update panel visible. Is this a bug with ASP.Net ajax? And does anyone have any ideas how to get around this? heres is an example of when im trying to to <script type="text/C#" runat="server"> protected void LinkButton1_Click(object sender, EventArgs e) { Panel1.Visible = true; } </script> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click" Text="Show Panel"></asp:LinkButton> </ContentTemplate> </asp:UpdatePanel> <asp:Panel ID="Panel1" runat="server" Visible="false"> <asp:UpdatePanel ID="UpdatePanel2" runat="server"> <ContentTemplate> blah bla blah </ContentTemplate> </asp:UpdatePanel> </asp:Panel> this is the javascript error that gets thrown when clicking on the "LinkButton1" link.

• How to perform two-way data binding of controls in a user control inside a FormView

  - by Sandor Drieënhuizen

  I'm trying to perform two-way data binding on the controls in my user control, which is hosted inside a FormView template. FormView: <asp:ObjectDataSource runat="server" ID="ObjectDataSource" TypeName="WebApplication1.Data" SelectMethod="GetItem" UpdateMethod="UpdateItem"> </asp:ObjectDataSource> <asp:FormView runat="server" ID="FormView" DataSourceID="ObjectDataSource"> <ItemTemplate> <uc:WebUserControl1 runat="server"></uc:WebUserControl1> </ItemTemplate> <EditItemTemplate> <uc:WebUserControl1 runat="server"></uc:WebUserControl1> </EditItemTemplate> </asp:FormView> User control: <%@ Control Language="C#" ... %> <asp:TextBox runat="server" ID="TitleTextBox" Text='<%# Bind("Title") %>'> </asp:TextBox> The binding works fine when the FormView is in View mode but when I switch to Edit mode, upon calling UpdateItem on the FormView, the bindings are lost. I know this because the FormView tries to call an update method on the ObjectDataSource that does not have an argument called 'Title'. I tried to solve this by implementing IBindableTemplate to load the controls that are inside my user control, directly into the templates (just like I had entered them declaratively like in the code above). However, when calling UpdateItem in edit mode, the container that gets passed into the ExtractValues method of the template, does not contain the TextBox anymore. It did in view mode! I have found some questions on SO that relate to this problem but they are rather dated and they don't provide any answers that helped me solve this problem. How do you think I could solve this problem? It seems to be such a simple requirement but apparently it's more like opening a can of worms...

• How to load static files from view HTML in web2py?

  - by MikeWyatt

  Given a view with layout, how can I load static files (CSS and JS, essentially) into the <head> from the view file? layout.html <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="{{=T.accepted_language or 'en'}}"> <head> <title>{{=response.title or request.application}}</title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <!-- include requires CSS files {{response.files.append(URL(request.application,'static','base.css'))}} {{response.files.append(URL(request.application,'static','ez-plug-min.css'))}} --> {{include 'web2py_ajax.html'}} </head> <body> {{include}} </body> </html> myview.html {{extend 'layout.html'}} {{response.files.append(URL(r=request,c='static',f='myview.css'))}} <h1>Some header</h1> <div> some content </div> In the above example, the "myview.css" file is either ignored by web2py or stripped out by the browser. So what is the best way to load page-specific files like this CSS file? I'd rather not stuff all my static files into my layout.

• Doctrine unsigned validation error storing created_at

  - by Alex Dean

  Hi, I'm having problems with the Timestampable functionality in Doctrine 1.2.2. The error I get on trying to save() my Record is: Uncaught exception 'Doctrine_Validator_Exception' with message 'Validation failed in class XXX 1 field had validation error: * 1 validator failed on created_at (unsigned) ' in ... I've created the relevant field in the MySQL table as: created_at DATETIME NOT NULL, Then in setTableDefinition() I have: $this->hasColumn('created_at', 'timestamp', null, array( 'type' => 'timestamp', 'fixed' => false, 'unsigned' => false, 'primary' => false, 'notnull' => true, 'autoincrement' => false, )); Which is taken straight from the output of generateModelsFromDb(). And finally my setUp() looks like: public function setUp() { parent::setUp(); $this->actAs('Timestampable', array( 'created' => array( 'name' => 'created_at', 'type' => 'timestamp', 'format' => 'Y-m-d H:i:s', 'disabled' => false, 'options' => array() ), 'updated' => array( 'disabled' => true ))); } (I've tried not defining all of those fields for 'created', but I get the same problem.) I'm a bit stumped as to what I'm doing wrong - for one thing I can't see why Doctrine would be running any unsigned checks against a 'timestamp' datatype... Any help gratefully received! Alex

• SimpleDOM sortedXPath date sorting works on localhost but not on remote server.

  - by Imminent

  Here's what i'm trying to do: 1) Take a basic XML page (data.xml) 2) Load it with simpleDOM 3) Use simpleDOM sortedXPath to sort all XML items by their pubDate 4) Display sorted output Here is the code I currently have. My code below outputs exactly what I need when run it on my localhost (XAMPP w/PHP 5.3) but on my remote server (which has at least PHP 5.0+) all is lost and a completely blank page is output. It will output the $xml array with print_r though. Here is my code: <?php include('SimpleDOM.php'); $xml = simpledom_load_file('data.xml'); $dateformat = "D j M, g:ia"; /* print_r($xml); <-array will output on remote server if put here, but alas nothing else beyond this point */ /*Output First 5 items sorted by pubDate*/ foreach($xml->channel->sortedXPath('item','pubDate', SORT_DESC) as $i => $item){ if ($i > 4){ break; } print "<p>This Weeks Deal:<strong> ".$item->title."</strong></p>"; print $item->description; print "<p>Date Posted:<strong> ".date($dateformat, strtotime($item->pubDate))."</strong></p>"; } ?> Like I said, this code seems to work great on my localhost... but not being able to run it on my remote server is making me crazy. Any ideas ?? Any help will be far beyond appreciated.

• Change made in the Converter will notify the change in the bound property?

  - by Kishore Kumar

  I have two property FirstName and LastName and bound to a textblock using Multibinidng and converter to display the FullName as FirstName + Last Name. FirstName="Kishore" LastName="Kumar" In the Converter I changed the LastName as "Changed Text" values[1] = "Changed Text"; After executing the Converter my TextBlock will show "Kishore Changed Text" but Dependency property LastName is still have the last value "Kumar". Why I am not getting the "Changed Text" value in the LastName property after the execution?. Will the change made at converter will notify the bound property? <Window.Resources> <local:NameConverter x:Key="NameConverter"></local:NameConverter> </Window.Resources> <Grid> <TextBlock> <TextBlock.Text> <MultiBinding Converter="{StaticResource NameConverter}"> <Binding Path="FirstName"></Binding> <Binding Path="LastName"></Binding> </MultiBinding> </TextBlock.Text> </TextBlock> </Grid> Converter: public class NameConverter:IMultiValueConverter { #region IMultiValueConverter Members public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) { values[1] = "Changed Text"; return values[0].ToString() + " " + values[1].ToString(); } public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } #endregion }

• WPF - expander Collapsed event being triggered by child controls with validation

  - by Shaboboo

  I have an expander that contains an ItemsControl. The items in the itemsControl are templated, some have textboxes in them, others have checkboxes. Both have bindings that cause validation. The styling and validation is working as expected. The problem is when I first expand the expander and cause a change to either control, the expander collapses again, this is not what I want. If I repeat this a second time this does not happen. I'm not sure what is triggering this strange behaviour. I've tried setting the focus to the itemsControl when the expander expands with no luck. What is differnt the second time it's expanded? Could it be the validation? Any Ideas? XAML: <Expander Header="{Binding SubSectionName}" Padding="0" > <ItemsControl ItemsSource="{Binding ConfigSubSectionSettings}" ItemTemplateSelector="{StaticResource Settings_Selector}" /> </Expander> <!-- Templates selected by the ItemTemplateSelector --> <DataTemplate x:Key="subSection_Bool"> <StackPanel Orientation="Horizontal"> <TextBlock x:Name="lbl" Text="{Binding SubSectionName}" > <CheckBox x:Name="chk" IsChecked="{Binding BoolValue, ValidatesOnDataErrors=True}" VerticalAlignment="Center" Margin="2" > </StackPanel > </DataTemplate> <DataTemplate x:Key="subSection_Text"> <StackPanel Orientation="Horizontal"> <TextBlock x:Name="lbl" Text="{Binding SubSectionName}" /> <TextBox x:Name="txt" VerticalAlignment="Center" Text="{Binding StringValue, ValidatesOnDataErrors=True}" /> </StackPanel> </DataTemplate>

• Form is submitting when the page loads

  - by RailAddict

  I have a really simple Rails app. Basically an article with comments. I want the article page to show the article, comments underneath and then a textbox to write a comment and a submit button to submit it. I got it all working except for one (big) problem. When the page loads.. example.com/article/1 a blank comment is submitted to the database. I fixed that by including "validates_presence_of :body" in the Comment model. But that results in the following image when the page loads: This is my code by the way: def show @place = Article.find(params[:id]) @comment = Article.find(params[:id]).comments.create(params[:comment]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @article } end end and <% form_for([@article, @comment]) do |f| %> <p> <%= f.label :commenter %><br /> <%= f.text_field :commenter %> </p> <p> <%= f.label :body %><br /> <%= f.text_area :body %> </p> <p> <%= f.submit "Create" %> </p> <% end %>

• Year split in Quarters using basic jQuery

  - by Alexander Corotchi

  Hi, I have a interesting question: I want to split the year into 4 quarters.
