  • XML Validation in ASP.NET MVC during load

    - by Jamie Nordmeyer
    I'm writing an ASP.NET MVC 2 application where one of the backing stores I plan to support is XML. I have a POCO that represents the settings for the site, along with an XML file to contain these settings. My question is what is the best way to validate this data as it is read from disk in to the POCO? I know I can use an XSD, or maybe use the Data Annotations library to mark up the POCO, and use reflection to validate the data, but is there another way, perhaps in .NET 3.5 or MVC to do this? I've spent some time Googling this issue, and want to be sure I'm doing it in the best manner. Thanks in advance!

  • How to send complex types from PHP SoapClient to ASP.NET SOAP server?

    - by xaguilars
    Hello I'm having problems sending arrays, structs and arrays of structs from PHP to an ASP.NET SOAP server... Anyone have a sollution for this? I've googled for days and any sollution worked for me. Perphaps I'm forgetting something... There are examples of my code: $client = new SoapClient($options); $pCriteria = new stdClass(); $pCriteria->type=1; $pCriteria->capacity=4; //Test 1 (fail): $resp = $client->GetRooms(array("pCriteria"=>$pCriteria)); //Test 2 (fail): $resp = $client->GetRooms(array("pCriteria"=>new SoapVar($pCriteria, SOAP_ENC_OBJECT, "TCriteria", "http://www.w3.org/2001/XMLSchema"))); print_r($resp); I don't know how to code functions that require an array of TCriteria (TCriteria[], TCriteria_Array type) either... i've tried sending the raw array, a SoapVar with SOAP_ENC_ARRAY encoding and TCriteria_Array type, ... but it does not work (the SOAP server becomes unavaiable and needs to be restarted). I've tried creating classes for the complex types too, instead of stdClass, but not working. I don't know where's the problem. The server admins cannot help me and I haven't found any sollution over internet. I'm a bit desperate hehe. Can you help me please? Can you provide samples of code with the three cases (array of simple data, array of struct and struct) ? Thanks!

  • ASP.Net Web Site Project vs. Web Application Project

    - by user144612
    I'm trying to convince my co-workers to switch from a web site project to a web application project, because I want the use of the project file. However I can't diffuse this argument against: The web site project allows each page to be compiled into a single dll. Their argument is this enables easy fixing of errors found after publishing. This is contrast to how the web application project compiles all code behind into a single dll. Is updating a single page's dll essentially different to updating the entire site's dll? Is there some way to compile each page's code behind into a seperate dll in the web application project? Are there some prohibitive (performance,memory?) costs to compiling each page's code behind into seperate dll's that we are unaware of? Why is the feature(?) to compile each page to separate dlls in web site projects and not web app projects?

  • ASP.NET MVC 2 relative paths for scripts and styles

    - by Tomaszewski
    Hi, having this really silly problem in ASP.NET MVC 2 with .NET 4. I need to test other pages using localhost, but sometimes I need to show the page to some else on another computer and so need to path out to my machine. In doing so, I need to use relative paths for my and tags. When I test through VS, I use relative path: <script src="../../Scripts/somejavascript.js"></script> <link href="../../Styles/somestyle.css" /> However, when I publish to local IIS, I'm having all sorts of problems beacuse the Scripts and Styles folder are at the same directory level, but it seems like I have to path out differently. For example, in the scenario above the styles will be picked up but the JavaScript won't be. Any ideas on how best to path out, relatively using MVC 2?

  • Using ViewModel Pattern with MVC 2 Strongly Typed HTML Helpers

    - by Brettski
    I am working with ASP.NET MVC2 RC and can't figure out how to get the HTML helper, TextBoxfor to work with a ViewModel pattern. When used on an edit page the data is not saved when UpdateModel() is called in the controller. I have taken the following code examples from the NerdDinner application. Edit.aspx <%@ Language="C#" Inherits="System.Web.Mvc.ViewUserControl<NerdDinner.Models.DinnerFormViewModel>" %> ... <p> // This works when saving in controller (MVC 1) <label for="Title">Dinner Title:</label> <%= Html.TextBox("Title", Model.Dinner.Title) %> <%= Html.ValidationMessage("Title", "*") %> </p> <p> // This does not work when saving in the controller (MVC 2) <label for="Title">Dinner Title:</label> <%= Html.TextBoxFor(model => model.Dinner.Title) %> <%= Html.ValidationMessageFor(model=> model.Dinner.Title) %> </p> DinnerController // POST: /Dinners/Edit/5 [HttpPost, Authorize] public ActionResult Edit(int id, FormCollection collection) { Dinner dinner = dinnerRepository.GetDinner(id); if (!dinner.IsHostedBy(User.Identity.Name)) return View("InvalidOwner"); try { UpdateModel(dinner); dinnerRepository.Save(); return RedirectToAction("Details", new { id=dinner.DinnerID }); } catch { ModelState.AddModelErrors(dinner.GetRuleViolations()); return View(new DinnerFormViewModel(dinner)); } } When the original helper style is used (Http.TextBox) the UpdateModel(dinner) call works as expected and the new values are saved. When the new (MVC2) helper style is used (Http.TextBoxFor) the UpdateModel(dinner) call does not update the values. Yes, the current values are loaded into the edit page on load. Is there something else which I need to add to the controller code for it to work? The new helper works fine if I am just using a model and not a ViewModel pattern. Thank you.

  • Adding Listeners at runtime? - Java MVC

    - by Halo
    My model in my MVC pattern, generates components at runtime and gives them to the View to be displayed on the screen through update() method (you know, model is the observable and the view is the observer). But I also need to add listeners to these components, and the controller has the listener methods (because they say the MVC pattern is like this) and it's not involved in this update process. So I can't add the listeners at runtime, but only in the controller's constructor at startup. I've got an idea, that is making the controller the observer and then giving the data to the view, as well as adding the listeners. Do you think this would be OK?

  • How can I use System.Web.Caching.Cache in a Console application?

    - by Ron Klein
    Context: .Net 3.5, C# I'd like to have caching mechanism in my Console application. Instead of re-inventing the wheel, I'd like to use System.Web.Caching.Cache (and that's a final decision, I can't use other caching framework, don't ask why). However, it looks like System.Web.Caching.Cache is supposed to run only in a valid HTTP context. My very simple snippet looks like this: using System; using System.Web.Caching; using System.Web; Cache c = new Cache(); try { c.Insert("a", 123); } catch (Exception ex) { Console.WriteLine("cannot insert to cache, exception:"); Console.WriteLine(ex); } and the result is: cannot insert to cache, exception: System.NullReferenceException: Object reference not set to an instance of an object. at System.Web.Caching.Cache.Insert(String key, Object value) at MyClass.RunSnippet() So obviously, I'm doing something wrong here. Any ideas? Update: +1 to most answers, getting the cache via static methods is the correct usage, namely HttpRuntime.Cache and HttpContext.Current.Cache. Thank you all!

  • Parsing JSON file with Python -> google map api

    - by Hannes
    Hi all, I am trying to get started with JSON in Python, but it seems that I misunderstand something in the JSON concept. I followed the google api example, which works fine. But when I change the code to a lower level in the JSON response (as shown below, where I try to get access to the location), I get the following error message for code below: Traceback (most recent call last): File "geoCode.py", line 11, in test = json.dumps([s['location'] for s in jsonResponse['results']], indent=3) KeyError: 'location' How can I get access to lower information level in the JSON file in python? Do I have to go to a higher level and search the result string? That seems very weird to me? Here is the code I have tried to run: import urllib, json URL2 = "http://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=false" googleResponse = urllib.urlopen(URL2); jsonResponse = json.loads(googleResponse.read()) test = json.dumps([s['location'] for s in jsonResponse['results']], indent=3) print test Thank you for your responses.

  • ASP.NET MVC project won't start under IIS 5.1 on Windows XP SP3

    - by mrjoltcola
    I've a ASP.NET MVC 2 project that runs fine under Windows 7 and will start on Windows XP if I use the Visual Studio Development Server, however, starting under IIS generates an error: Unable to start debugging on the web server With the message The specified procedure could not be found No errors in the system event viewer. If I start without debugging I get an "HTTP 500 Internal Server Error" The reason I run it under IIS is the project also includes some WCF wsHttp web services that use certificates, so the VS Development Server is not adequate for hosting those. I have already seen the links on SO that talk about adding the wildcard mapping. I've already done that, just as I've done on Windows Server 2003 where I successfully host ASP.NET MVC RC2 for quite a while.

  • selectors-api for data attributes

    - by MJ
    In HTML5, CSS selectors seem to operate well with data-* attributes. For example: <style> div[data-foo='bar'] { background:#eee; } </style> <div data-foo='bar'>colored</div> <div>not colored</div> will properly style the first . But, attempts to select such elements using the selectors-api fail. Examples: var foos = document.querySelectorAll("div[data-foo]='bar'"); or var foos = document.querySelectorAll("div data-foo='bar'"); in Chrome and Safari, this produces a cryptic error: SYNTAX_ERR: DOM Exception 12 Any thoughts on how to use the selectors-api to properly select elements on the basis of data-* attributes?

  • Anyone have any issues with using PLINQO and ASP.NET MVC 2.0?

    - by Chad
    I'm asking because I'm working on an ASP.NET MVC 1.0 site, thinking of upgrading to ASP.NET MVC 2.0. Then I read that PLINQO 5.0 was released (I had never heard of PLINQO before) and have been impressed with what PLINQO appears to be capable of. 1) Is PLINQO capable of building out an ASP.NET MVC 2.0 UI project when it's run? 2) Have you had any bad experiences using PLINQO (particularly in an ASP.NET MVC app)? Let me make sure I have the scenario right in my mind: Using PLINQO (assuming it supports ASP.NET MVC 2.0), I should be able to point it to my DB and it will create 3 projects: data, test, and mvc 2.0 UI? The data would contain LINQ to SQL queries, with the PLINQO extensions added in and the other projects setup to use the data project by default?

  • How to enable ajax when deriving from System.Web.UI.WebControls.WebControl on controls that are crea

    - by Dave
    I've built a class that derives from System.Web.UI.WebControl. It basically renders pagination links (same as what you see on top of GridView when enabled) for use above a repeater. I'm creating some anchor tags explicitly inside my nav control obviously, but they don't perform ajax postbacks. My understanding is that ajax requires POSTS to work right? Well, these would be GETs which I think is the problem. Is there a way to achieve what I'm trying to do? Thanks!

  • ASP.NET Panel FindControl within DataList to change property C#

    - by SDC
    I'm new to this ASP.NET stuff. In my page I have a Datalist with a FooterTemplate. In the footer I have a couple panels that will be visible depending on the QueryString. The problem I am having is trying to find these panels on Page_Load to change the Visible Property. For example this is part of the aspx page: <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server"> <asp:DataList ID="dlRecords" runat="server"> <FooterTemplate> <asp:Panel ID="pnlArticleHeader" runat="server" Visible="false" > </asp:Panel> </FooterTemplate> </asp:Datalist> </asp:Content> Here is something in the codebehind: protected void Page_Load(object sender, EventArgs e) { location = Request.QueryString["location"]; if (location == "HERE") { Panel pnlAH = *Need to find control here*; pnlAH.Visible=true; } } Like I said I am new at this. Everything I have found doesn't seem to work so I decided to post a specific question. Thanks in advance

  • which collection should I use

    - by Masna
    Hello, I have a number of custom objects of type X. X has a number of parameters and must be unique in the collection. (I created my own equals method based on the custom parameters to examine this) In each object of type x, I have a list of objects y. I want to add/remove/modify easily an object y. For example: To write the add method, it would be something like add(objTypeX, objTypeY) I would check or the collections already has a objTypeX. If so: i would add the objTypeY to the already existing objTypeX else: i would create objTypeX and add objTypeY to this object. To modify an objTypeY, it would be something like(objTypeX, objTypeY, newobjTypeY) I would get objTypeX out of the collections and modify objTypeY to newobjTypeY Which collections should I use? I tried with hashset but i can get a specific object out of the list, without run down the list till I find that object. I develop this in vb.net 3.5
