  • Firefox not honoring must-revalidate cache headers returned by jQuery.ajax() request

    - by Oliver Weichhold
    UPDATE 1: Judging by this thread I am not the only one having this problem in FF 12 and only in 12. UPDATE 2: The problem does not seem to be limited to Ajax requests. From the looks of it everything that makes it into Firefox 12's cache will be fetched from there. No matter what. The server can specify cache control headers all day long. Bummer! What I'm trying to achieve is the following behavior: Browser may cache the response without revalidating for up to 5 minutes I don't care if the browser revalidates on every request (Both Chrome and IE9 do for example) When the expiration is up the browser MUST revalidate (which in my case will result in fresh data) Chrome and IE9 exhibit the desired behavior when issuing a jquery.ajax() request with ifModified: true and cache: true while Firefox 12 never revalidates, which poses a serious problem. These are the actual response headers: HTTP/1.1 200 OK Server: nginx Date: Sun, 03 Jun 2012 07:13:43 GMT Content-Type: text/javascript; charset=UTF-8 Transfer-Encoding: chunked Connection: keep-alive Vary: Accept-Encoding Cache-Control: private, must-revalidate, max-age=300 Last-Modified: Sun, 03 Jun 2012 07:07:13 GMT Content-Encoding: gzip Any suggestions?

  • Omit Properties from WebControl Serialization

    - by Laramie
    I have to serialize several objects inheriting from WebControl for database storage. These include several unecessary (to me) properties that I would prefer to omit from serialization. For example BackColor, BorderColor, etc. Here is an example of an XML serialization of one of my controls inheriting from WebControl. <Control xsi:type="SerializePanel"> <ID>grCont</ID> <Controls /> <BackColor /> <BorderColor /> <BorderWidth /> <CssClass>grActVid bwText</CssClass> <ForeColor /> <Height /> <Width /> ... </Control> I have been trying to create a common base class for my controls that inherits from WebControl and uses the "xxxSpecified" trick to selectively choose not to serialize certain properties. For example to ignore an empty BorderColor property, I'd expect [XmlIgnore] public bool BorderColorSpecified() { return !base.BorderColor.IsEmpty; } to work, but it's never called during serialization. I've also tried it in the class to be serialized as well as the base class. Since the classes themselves might change, I'd prefer not to have to create a custom serializer. Any ideas?

  • EF in a UserControl can't see the app.config?

    - by Sven
    I just created a user control. This control also makes use of my static Entity Framework class to load two comboboxes. All is well and runs without a problem. Design and runtime are working. Then when I stop the application all the forms that contain my UserControl don't work any more in design time. I just see two errors: Error1: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. Error 2: The variable ccArtikelVelden is either undeclared or was never assigned. (ccArtikelVelde is my UserControl) Runtime everything is still working My static EF Repositoy class: public class BSManagerData { private static BSManagerEntities _entities; public static BSManagerEntities Entities { get { if (_entities == null) _entities = new BSManagerEntities(); return _entities; } set { _entities = value; } } } Some logic happening in my UserControl to load the data in the comboboxes: private void LaadCbx() { cbxCategorie.DataSource = (from c in BSManagerData.Entities.Categories select c).ToList(); cbxCategorie.DisplayMember = "Naam"; cbxCategorie.ValueMember = "Id"; } private void cbxCategorie_SelectedIndexChanged(object sender, EventArgs e) { cbxFabrikant.DataSource = from f in BSManagerData.Entities.Fabrikants where f.Categorie.Id == ((Categorie)cbxCategorie.SelectedItem).Id select f; cbxFabrikant.DisplayMember = "Naam"; cbxFabrikant.ValueMember = "Id"; } The only way to make my forms work again, design time, is to comment out the EF part in the UserControl (see above) and rebuild. It's very strange, everything is in the same assembly, same namespace (for the sake of simplicity). Anyone an idea?

  • Is it possible to setup a .NET4 webforms route to an asmx endpoint?

    - by Astrofaes
    Is it possible in my RegisterRoutes method in global.asax, to map some routes to an asmx? Ideally I would like to do something like: routes.MapPageRoute("ServiceSearchCats", "services/search/cats", "~/Services/Search.asmx/Cats"); (and therefore my endpoint for the service becomes "http://mydomain.com/services/search/cats", instead of the ugly "http://mydomain.com/Services/Search.asmx/Cats" url)

  • Problems with Unity BuildUp Method

    - by Voice
    Hi everybody) I'm using Unity App Block for my project (version 1.2.0.0). I have a problem with Unity Container BuildUp method which I'm using for my ascx controls. Here is some code (that's pretty simple) public class BaseUserControl<T>:UserControl where T:class { protected override void OnInit(EventArgs e) { InjectDependencies(); base.OnInit(e); } protected virtual void InjectDependencies() { var context = HttpContext.Current; if (context == null) { return; } var accessor = context.ApplicationInstance as IContainerAccessor; if (accessor == null) { return; } var container = accessor.Container; if (container == null) { throw new InvalidOperationException("No Unity container found"); } container.BuildUp<T>(this as T); } } This method is called in base control for ascx controls in my solution. And here the property that should be injected in child control: [Dependency] private IStock Stock { get; set; } So after buildup Stock property is still empty. Resolve method works fine for IStock with the same container and configuration. I've tried buildup with simple test class with only one property IStock and got the same result. So what can be wrong with buildup?

  • Updating a Database from DataBound Controls

    - by Avatar_Squadron
    Hi. I'm currently creating a WinForm in VB.NET bound to an access database. Basically what i have are two forms: one is a search form used to search the database, and the other is a details form. You run a search on the searchForm and it returns a list of Primary Keys and a few other identifying values. You then double click on the entry you want to view, and it loads the details form. The Details form has a collection of databound controls to display the data: mostly text boxes and checkboxs. The way i've set it up is i used the UI to build the form and then set the DataBindings Property of each control to "TblPropertiesBindingSource - " where value name is one of the values in the table (such as PropertyID or HasWoodFloor). Then, when you double click an entry in the searchform, I handle the event by parsing the Primary Key (PropertyID) out of the selected row and then storing this to the details form: Note: Detail is the details form that is opened to display the info Private Sub propView_CellDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles propView.CellDoubleClick Dim detail As frmPropertiesDetail = New frmPropertiesDetail detail.id = propView.Rows(e.RowIndex).Cells(0).Value detail.Show() End Sub Then, upon loading the details form, it set's the filter on the BindSource as such: TblPropertiesBindingSource.Filter() = "PropertyID=" & id This works great so far. All the controls on the details form will display the correct info. The problem is updating changes. Scenario: If i have the user load the details for say, property 10001, it will show a description in a textBox named descriptionBox which is identical to the value of the description value of for that entry in the database. I want the user to then be able to change the text of the text box (which they can currently do) and click the save button (saveBut) and have the form update all the values in the controls to the database. Theorectically, it should do this as the controls are DataBound, thus i can avoid writing code that tells each entry in the database row to take the value of the aligned control. I've tried calleding PropertiesTableAdapter.Update(PropertiesBindingSource.DataSource), but that doesnt seem to do it.

  • Bind an Incode DataTemplate in WPF

    - by Mike Bynum
    I have a WPF Application which is using MVVM. I know that there ways of doing this in XAML but I am working on a plugin architecture and came up with a solution where a plugin exposes it's viewmodel to my plugin host's viewmodel and it's datatemplate. I want to leave the lifetime management of the plugin view up to WPF. I have tried having the plugins expose a UserControl but ran into issues when WPF decided to dispose of my UserControl so I would not reattach it without weird hacky work arounds. I am having issues getting some sort of binding working to where i can bind a control to the data and it's template to my data template. I have a ViewModel which looks something like: public class MyViewModel { public DataTemplate SelectedTemplate{ get; set;} public object SelectedViewModel {get; set;} } The selected template and viewmodel are determined somewhere else in the code but are irrelevant to my question. My question is how i can bind to a DataTemplate so that I know how to display the data shown in the SelectedViewModel. The DataTemplate is a DataTemplate created incode which respresents: <DataTemplate DataType="{x:Type vm:MyViewModel}"> <v:MyUserControl /> </DataTemplate> I have tried: <UserControl Template="{Binding Path=SelectedTemplate}" Content="{Binding Path=SelectedViewModel"} /> But UserControl expects a control template and not a data template.

  • Sybase PowerDesigner Change Many (Find/Replace/Convert) Data Item's Data Types

    - by Andy
    Hello, I have a relatively large Conceptual Data Model in PowerDesigner. After generating a Physical Data Model and seeing the DBMS data types, I need to update all of data types(NUMBER/TEXT) for each data item. I'd like to either do a find/replace within the Conceptual Data Model or somehow map to different data types when creating the Physical Data Model. Ex. Change the auto conversion of Text - Clob, to Text - NVARCHAR(20). Thanks!

  • Java Download Concurrent Data

    - by xger86x
    Hi, i'm developing an app which download map tiles around different places in a city. To do this, i have one thread for each place in which i select the tiles and create a thread to download each. Well, the question is how to avoid creating a thread for a tile that already exists in the thread pool. Should not just check if the file exists, since it is possible that the thread for that tile already exists (other place already need that tile) but the file has not been created- Any idea? Thanks

  • IE textarea wrap bug?

    - by user2227033
    It seems that IE starting from IE7 to IE10 wraps text in the textarea control incorrectly when using \n (or \r\n - doesn't matter - results are the same). Is this a bug in IE or they treat the html standard differently than other browsers - who is right? I have defined: <textarea id="TextArea1" runat="server" style="width: 190px; height: 390px; white-space: normal; word-wrap: normal; overflow: scroll" ></textarea> When I try to add long string like "VeryLongStringEndingWithNewLine\n" by using JavaScript code (obj.value += text;) the text is shown in one line with scroll (this is ok) but added with an additional empty line (\r\n) - why? When I try to add short string like "Short\n" multiple times, again via JavaScript code the text is on the same line (should be on the separate lines because normal wrapping should be applied). Moreover when I do postback then all \r\n's are replaced with spaces (why?) and then text parsed correctly (assuming if I used spaces instead of crlf normal wraping with space only wraps when does not fit in the area). When using FF or Chrome same control behaves correctly - long lines are shown without an additional empty next line, short lines are on the different lines, no replacement with spaces when doing postback. I know I could probably use other options or white space characters, but I feel that above is not correct about IE. Any comments? Mindaugas

  • ruby on rails basics help

    - by CHID
    Hi, i created a scaffolded application in rails by the name of product. The product_controller.rb file contains the following. class ProductsController ApplicationController def new @product = Product.new respond_to do |format| format.html # new.html.erb format.xml { render :xml = @product } end end def create @product = Product.new(params[:product]) respond_to do |format| if @product.save flash[:notice] = 'Product was successfully created.' format.html { redirect_to(@product) } format.xml { render :xml = @product, :status = :created, :location = @product } else format.html { render :action = "new" } format.xml { render :xml = @product.errors, :status = :unprocessable_entity } end end end Now when the url http://localhost:3000/products/create is given Where new product link is clicked, control is transferred to new definition in the controller class and then an instance variable @product is created. BUT WHERE IS THIS VARIABLE PASSED? The funtion inturn calls new.rhtml which contains <% form_for(@product) do |f| % #all form elments declaration <% f.submit "Create" % <%= end % Here @product is initialized in the controller file and passed to this new.rhtml. So where does form_for(@product) gets the data? How does the control gets tranfered to create function in controller file when submit button is clicked? No where action is specified to the controller file. in the create function, wat does redirec_to(@product) specify where @product is an object received from the new.html file... I am very much confused on the basics of ROR. Somone pls help me clarify this. pardon me for making such a big post. I have lots of doubts in this single piece of code

  • What is the proper way to wrap this php loop around the javascript

    - by zac
    Hi, I am mashing together the Google Maps 2 script with a Wordpress loop so there is a CMS platform for the map data. I have this working fine : var point = new GLatLng(48.5139,-123.150531); var marker = createMarker(point,"Lime Kiln State Park", '<?php $post_id = 182; $my_post = get_post($post_id); $mapTitle = $my_post->post_title; $mapIMG = get_post_meta($post_id, 'mapImage', true); $snip = get_post_meta($post_id, 'mapExcerpt', true); echo "<div class=\"span-12\">"; echo "<div class=\"mapTitle\">"; echo $mapTitle; echo "</div>"; echo "<img class=\"mapImage\" src=\""; echo bloginfo('url'); echo "/wp-content/files_mf/"; echo $mapIMG; echo "\" /> "; echo "<div class=\"mapContent\">"; echo $snip; echo "</div>"; echo "<div class=\"moreLink\">"; echo "<a href=\""; echo $permalink = get_permalink( $post_id ); echo "\">Find out more &raquo; </a>"; echo "</div>"; echo "</div>"; ?>') map.addOverlay(marker); However I am hoping to also be able to include the two variables at the start within the php loop so that both of those can also be generated by custom fields. Can someone please show me that the proper way to write this would be so that all of the data can be pulled in from fields within that post id? So the lat/long and title could also be set from within the post 182 fields.

  • Silverlight Not Rendering On Navigation

    - by Azmath
    I'm trying to create a site that requires login. Its entirely designed in silverlight. So my first page, home.xaml loads in mysite.aspx and it basically has a login page. AFter login, the user is redirected to another page user.aspx. in that page, i've embedded another silverlight control called nav.xaml. so now when user.aspx loads it is supposed to load a silverlight control. i've programmed app.xaml.vb such that it loads nav.xaml in the rootlayout when the page requesting is user.aspx. but for some reason its not working. my app.xaml.vb code: Private Sub Application_Startup(ByVal o As Object, ByVal e As StartupEventArgs) Handles Me.Startup If e.InitParams.ContainsKey("ReqPage") Then If e.InitParams("ReqPage") = "userpage" Then Me.RootVisual = New Nav() End If Else Me.RootVisual = New Home() End If End Sub in IE, half of the nav.xaml is rendered. but in firefox nothing is rendered. so wats going on exactly? pls help!

  • How to handle 30k files in a project which requires them?

    - by Jeremiah
    Visual Studio 2010 RC - Silverlight Application We have a library of images that we need to have access to. They are given to us from a vendor (through an installer) and they are not in a database, they are files in a folder (a very large monster of a folder). We do not control when the images change, so the vendor needs to be able to override them individually. We get updates frequently enough from this vendor to state that these images change "randomly" and without our (programmer) knowledge. The problem: I don't want 30K images in SVN. Heck, I don't even want to imagine them in my Solution. However, our application requires them in order to run properly. So, our build/staging servers need access to these images (we have two build servers). The Question: How would you handle it when your application will not work as specified without access to each of 30k images and you don't control when those images change? I'm do not want to have a crazy large SVN repository. Because I don't know when any of these images change, I really don't want them in my solution (definitely do not want a large solution, either). I also don't want a bunch of manual steps to do every time these images change. Our mantra, up to this point, has always been, any developer could download from SVN, compile and run our app. These images are going to kill that mantra. I'm tempted to make a WCF service that will return images if they exist and a dummy image if they don't. This way all dev boxes will return a dummy image and our build/staging/production boxes will return real images (ones that actually have the vendor's image installer installed on). This has to be a solved problem. What have other people done to handle these types of problems? I'm open to suggestions.
