  • What is a practical usage of Code Contracts in .NET 4.0?

    - by Will Marcouiller
    In order to fully understand and take advantage of the new features and enhancements provided with the coming of the new .NET Framework 4.0, I would like to get an example of real-world application of the Code Contracts. Anyone has a good example of application of this feature? I would like to get a code sample with a brief explanation to help me get up and running with it. Thanks! =)

  • How can I locate .NET Library property/function that return a particular type?

    - by Michael Bray
    Occasionally I will know that there is a .NET Framework function that returns a particular type of object, but I can't recall the property or function name. It would be really nice to be able to somehow scan the Framework or other DLL for functions that return a particular type of object. (For example, it would have helped when I asked this question, and I have a similar question again.) Can anyone suggest how I might do this?

  • ASP.NET C# Write RSS feed for Froogle

    - by Peter
    Hi, I'm trying to create a RSS 2.0 feed in ASP.NET C# with products to provide to Froogle. The RSS feed should look like: http://www.google.com/support/merchants/bin/answer.py?answer=160589&hl=en I'm using the SyndicationFeed and SyndicationsItems to create the feed. But I'm having trouble adding the extra elements like g:image_link. I try the extra elements like; syndicationItem.ElementExtensions.Add(new XElement("image_link", product.ImageLink).CreateReader()); This works, but how can I add the namespace xmlns:g="http://base.google.com/ns/1.0" to the first RSS tag and use this for the extension elements? Thank you

  • Issue with WIC image resizing on ASP.NET MVC 2

    - by Dave
    I am attempting to implement image resizing on user uploads in ASP.NET MVC 2 using a version of the method found: here on asp.net. This works great on my dev machine, but as soon as I put it on my production machine, I start getting the error 'Exception from HRESULT: 0x88982F60' which is supposed to mean that there is an issue decoding the image. However, when I use WICExplorer to open the image, it looks ok. I've also tried this with dozens of images of various sources and still get the error (though possible, I doubt all of them are corrupted). Here is the relevant code (with my debugging statements in there): MVC Controller [Authorize, HttpPost] public ActionResult Upload(string file) { //Check file extension string fx = file.Substring(file.LastIndexOf('.')).ToLowerInvariant(); string key; if (ConfigurationManager.AppSettings["ImageExtensions"].Contains(fx)) { key = Guid.NewGuid().ToString() + fx; } else { return Json("extension not found"); } //Check file size if (Request.ContentLength <= Convert.ToInt32(ConfigurationManager.AppSettings["MinImageSize"]) || Request.ContentLength >= Convert.ToInt32(ConfigurationManager.AppSettings["MaxImageSize"])) { return Json("content length out of bounds: " + Request.ContentLength); } ImageResizerResult irr, irr2; //Check if this image is coming from FF, Chrome or Safari (XHR) HttpPostedFileBase hpf = null; if (Request.Files.Count <= 0) { //Scale and encode image and thumbnail irr = ImageResizer.CreateMaxSizeImage(Request.InputStream); irr2 = ImageResizer.CreateThumbnail(Request.InputStream); } //Or IE else { hpf = Request.Files[0] as HttpPostedFileBase; if (hpf.ContentLength == 0) return Json("hpf.length = 0"); //Scale and encode image and thumbnail irr = ImageResizer.CreateMaxSizeImage(hpf.InputStream); irr2 = ImageResizer.CreateThumbnail(hpf.InputStream); } //Check if image and thumbnail encoded and scaled correctly if (irr == null || irr.output == null || irr2 == null || irr2.output == null) { if (irr != null && irr.output != null) irr.output.Dispose(); if (irr2 != null && irr2.output != null) irr2.output.Dispose(); if(irr == null) return Json("irr null"); if (irr2 == null) return Json("irr2 null"); if (irr.output == null) return Json("irr.output null. irr.error = " + irr.error); if (irr2.output == null) return Json("irr2.output null. irr2.error = " + irr2.error); } if (irr.output.Length > Convert.ToInt32(ConfigurationManager.AppSettings["MaxImageSize"]) || irr2.output.Length > Convert.ToInt32(ConfigurationManager.AppSettings["MaxImageSize"])) { if(irr.output.Length > Convert.ToInt32(ConfigurationManager.AppSettings["MaxImageSize"])) return Json("irr.output.Length > maximage size. irr.output.Length = " + irr.output.Length + ", irr.error = " + irr.error); return Json("irr2.output.Length > maximage size. irr2.output.Length = " + irr2.output.Length + ", irr2.error = " + irr2.error); } //Store scaled and encoded image and thumbnail .... return Json("success"); } The code is always failing when checking if the output stream is null (i.e. irr.output == null is true).

  • Ninject : ninject.web - How to apply on a regular ASP.Net Web (!MVC)

    - by No Body
    What I am looking is something similar to the below (http://github.com/ninject/ninject.web.mvc): README.markdown This extension allows integration between the Ninject core and ASP.NET MVC projects. To use it, just make your HttpApplication (typically in Global.asax.cs) extend NinjectHttpApplication: public class YourWebApplication : NinjectHttpApplication { public override void OnApplicationStarted() { // This is only needed in MVC1 RegisterAllControllersIn("Some.Assembly.Name"); } public override IKernel CreateKernel() { return new StandardKernel(new SomeModule(), new SomeOtherModule(), ...); // OR, to automatically load modules: var kernel = new StandardKernel(); kernel.AutoLoadModules("~/bin"); return kernel; } } Once you do this, your controllers will be activated via Ninject, meaning you can expose dependencies on their constructors (or properties, or methods) to request injections.

  • Cannot use Html.ActionLink in asp.net mvc spark files

    - by midas06
    I'm using the spark view engine with my asp.net mvc application. In my aspx pages, I can succesfully use Html.Actionlink, but when I attempt it in spark files, it doesnt show up in intellisense, and when i try to run it anyway, i get: Dynamic view compilation failed. c:\Users\midas\Documents\Visual Studio 2008\Projects\ChurchMVC\ChurchMVC\Views\Home\Index.spark(73,25): error CS1061: 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'ActionLink' and no extension method 'ActionLink' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found (are you missing a using directive or an assembly reference?) I do have system.web.mvc referenced, and I have added in _global.spark. None of that helps. Any ideas?

  • Firefox Extension needs to get cookie from PHP redirected external page.

    - by Tyler
    I am writing a firefox extension that interacts with a JSON server interface. I receive a url to the server which then redirects to the client site that provides the cookie. I need to be able to set this cookie in the users browser without physically loading it in the browser. Is this possible through an AJAX call? I tried using a hidden iframe, however firefox does not seem to like a php redirect in the iframe. My current solution is to load the site in a second tab that never gains focus and then auto close it when the cookie is set. This is very messy and would prefer something more streamlines. Any thoughts?

  • asp.net MVC - how to get complete local and global resources

    - by Buthrakaur
    I'm localizing application and need to provide JSON representation of local and global resources for JS part of application for all views. My current idea is I'd implement HtmlHelper extension methods like GetLocalResourcesJSON/GetGlobalResourcesJSON which should encode all resource keys+values and return them JSON encoded as string (I'd implement caching as well). At the moment I'm able to retrieve single specific key from global or local resource belonging to current view (using httpContext.GetGlobalResourceObject/GetLocalResourceObject), but I'm not able to find out how to retrieve whole resource object and iterate all its keys+values. Is there any method how to achieve this? it looks like ResourceProviderFactory could be the the key to this problem, but it's not accessible publicly anywhere. I could instantiate ResourceExpressionBuilder and use reflection to retrieve the provider using GetLocal/GlobalResourceProvider() methods, but I don't like using reflection here at all...

  • ff extension. how to pass parameters to a function in the oncommand attribute in menu

    - by encryptor
    I have a ff extension which creates a popup and shows dynamic data in it. basically when the popup opens a js function is run which then constructs the popup list by appending the items like this var myMenuPopup = document.getElementById("file-popup4"); newItem = document.createElement("menuitem"); newItem.setAttribute("label", namelist[m]); newItem.setAttribute("id", "item" + m); Now I need to have the click functionality too on these newly added menuitems. putting the atttribute and forming the function is easy. I can have a function to be run when they are clicked. But i need to pass namelist[i] to the function and it will act according to the namelist parameter.If i do: newItem.setAttribute("oncommand" , finalclick(namelist[m])); it runs the function everytime the popup opens runs the function without even clicking on it on the other hand if i use quotes i.i if i do newItem.setAttribute("oncommand" , "finalclick(namelist[m])"); it doesnot open even on clicking giving error : namelist is not defined.

  • ASP.NET MVC download image rather than display in browser

    - by RSolberg
    Rather than displaying a PNG in the browser window, I'd like the action result to trigger the file download dialogue box (you know the open, save as, etc). I can get this to work with the code below using an unknown content type, but the user then has to type in .png at the end of the file name. How can I accomplish this behavior without forcing the user to type in the file extension? public ActionResult DownloadAdTemplate(string pathCode) { var imgPath = Server.MapPath(service.GetTemplatePath(pathCode)); return base.File(imgPath, "application/unknown"); }

  • How can I access IEnumerable<T> extension methods on my custom subclass of BindingList<T>?

    - by Dan
    I have a custom subclass of BindingList<T> that I want to execute a LINQ query over using the handy extension methods. For example: public int GetSum(MyList<T> list) { return list.Sum(x => x.Value); } But the compiler complains that it can't resolve Sum because it doesn't recognize list as an IEnumerable<T>, which it obviously is, because this works: public int GetSum(MyList<T> list) { return ((IEnumerable<T>)list).Sum(x => x.Value); } Anyone have a clever way I can avoid the ugly and unecessary cast?

  • ASP.Net: Scheduled tasks in a shared environment.

    - by UpTheCreek
    This is really an extension of this question, which asked the best way to schedule tasks which need to be performed periodically within ASP.NET in a normal environment. However, I would like to ask this specifically for a Shared Hosting Environment (most of the answers to the previous question would not work in a shared environment as far as I know). One obvious solution would be to have a page which is responsible to performing the tasks on the hosted machine, and call this page from another machine (that you have full control over) using e.g. a windows scheduled task. This is a bit nasty though - are there any better approaches?

  • .NET Recaptcha https

    - by TygerKrash
    We've started using the ASP.NET recaptcha control and it works fine. but one of the requirements we have is that all outbound traffic goes over Https. I know that recaptcha supports https, but It's not clear how to configure (or even if it is configurable) when using the ASP.NET plugin option. has anyone got any experience of this? I'll expand a little on what I've found so far.... The Recaptcha package contains 3 public classes RecaptchaControl, RecaptchaValidator and RecaptchaResponse RecaptchaControl is an Asp.NET control, the recaptcha specific methods on there seem to be concerning themes/look and feel. An instance of the Validator has a RemoteIP field (which I presume would represent the verification server), but I can't a way of binding that to the control. RecaptchaResponse seems to more or less represent an enum with possible responses (valid/invalid/failed to connect).

  • Extension method question. Why do I need to use someObj = someObj.somemethod();

    - by Kettenbach
    Hi All, I have a simple extension method that I would like to use to add an item to an array of items. public static T[] addElement<T>(this T[] array, T elementToAdd) { var list = new List<T>(array) {elementToAdd}; return list.ToArray(); } this works ok, but when I use it, I am having to set the array equal to the return value. I see that I am returning an Array. I likely want this method to be void, but I would like the item added. Does anyone have any ideas on what I need to do , to make this work the way I am wanting? Instead of someArray = someArray.addElement(item), I just want to do someArray.addElement(item) and then someArray be ready to go. What am I missing here? Thanks, ~ck in San Diego

  • Asp.net profile in a separate assembly

    - by Shimrod
    Hi everyone, I have a web application which uses membership and profiles. I successfully used the WebProfileBuilder extension, so my profile class is correctly generated, and is working nicely. However, after a new request of my client, I need now to move that profile management part into another assembly (so I'd be able to get profile information in a windows service running on the same machine). What I made is created the new assembly, moved my generated profile file, and tried to use it from the other assembly, but without any success. I always get a SettingsPropertyNotFoundException. My tought is that the profile system doesn't know where to find its connection information, so I tried to add the connectionstring and provider in the app.config of this assembly, but this doesn't seem to work. What am I missing ? Is it possible to do ? Thanks in advance!
