• ASP.NET ReportViewer Google Chrome CPU usage

  - by Phil

  Hello, We have found an interesting issue between ASP.NET 3.5 and ReportViewer with Google Chrome. Our set of pages work fine until a ReportViewer control displays a report. Google Chrome then eats up 50% of the CPU doing nothing it seems. I've extracted the ReportViewer control to a blank Web Forms project to confirm its that control and not a rogue bit of my code. I'm using ReportViewer in local mode (RDLC file) so I presume its the 2005 version? Anyone seen this before and have a solution? Phil Edit: Google Chrome 3.0.195.33 on Vista Business x64 Edit 2: Added bounty for help fixing 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

• FireBug not working with ASP.NET MVC

  - by Stuart

  Hi All I have started a new ASP.NET MVC project and have included the ExtJS library files. This all works fine when built from Visual Studio and i can display various ExtJS objects. The problem however is that FireBug has stopped showing errors in the Console, even when i type nonsense into the code block. Setup is: VS 2008 SP1 FireBug 1.4.2 FireFox 3.5.2 Firebug is working with other public web sites and when viewing other PHP based sites I'm developing. Does anyone have any ideas what might be causing this? Thanks for any suggestions Stuart

• SimpleModal breaks ASP.Net Postbacks

  - by tghw

  I'm using jQuery and SimpleModal in an ASP.Net project to make some nice dialogs for a web app. Unfortunately, any buttons in a modal dialog can no longer execute their postbacks, which is not really acceptable. There is one source I've found with a workaround, but for the life of me I can't get it to work, mostly because I am not fully understanding all of the necessary steps. I also have a workaround, which is to replace the postbacks, but it's ugly and probably not the most reliable. I would really like to make the postbacks work again. Any ideas? UPDATE: I should clarify, the postbacks are not working because the Javascript used to execute the post backs has broken in some way, so nothing happens at all when the button is clicked.

• ASP.Net Application Trust Medium File IO Outside Virtual Directory

  - by Trey Gramann

  I am trying to determine how suicidal this is... I have a hosting environment where a custom ASP.Net CMS application needs to access the files in the root folder of a website even though it is in a virtual folder so it can be shared accross many sites. I can modify the Medium trust on the server and came up with this... <IPermission class="FileIOPermission" version="1" Read="$AppDir$;$AppDir$\.." Write="$AppDir$;$AppDir$\.." Append="$AppDir$;$AppDir$\.." PathDiscovery="$AppDir$;$AppDir$\.."/> Oddly enough, it works. Yes, I understand it is doing this for all the Apps. I am a bit at a loss as to easy ways to test what else is being exposed. Feels dangerous. Opinions?

• Printing PDFs Server-side using Acrobat Reader from ASP.NET

  - by Chris Roberts

  Hi, I have been presented with a problem which requires me to print PDF files from a server as part of an ASP.NET web service. The problem is further complicated by the fact that the PDF files I have to print can ONLY be printed using Adobe Reader (they were created using Adobe LiveCycle and have some strange protection in them). This piece of code seems to do the trick in the Visual Studio development web server, but doesn't do anything when the site's running in IIS. I'm assuming this is probably some sort of permissions issue!? I know this is a FAR from ideal thing to be trying to do, but I haven't really got much choice! Any ideas would be greatly appreciated! Dim starter As ProcessStartInfo Dim Prc As Process ' Pass File Path And Arguments starter = New ProcessStartInfo("c:\program files\...\AcroRd32.exe", "/t ""test.pdf"" ""Printer""") starter.CreateNoWindow = True starter.RedirectStandardOutput = True starter.UseShellExecute = False ' Start Adobe Process Prc = New Process() Prc.StartInfo = starter Prc.Start()

• Replace text in Word Document via ASP.NET

  - by jreedinc

  How can I replace a string/word in a Word Document via ASP.NET? I just need to replace a couple words in the document, so I would like to stay AWAY from 3rd party plugins & interop. I would like to do this by opening the file and replacing the text. The following attempts were made: I created a StreamReader and Writer to read the file but I think that I am reading and writing in the wrong format. I think that Word Documents are stored in binary?? If word documents are binary, how would I read and write the file in binary? Dim template As String = Request.MapPath("documentName.doc") If File.Exists(template) Then Dim sr As New StreamReader(template) Dim content As String = sr.ReadToEnd() sr.Close() Dim sw As New StreamWriter(template) content = content.Replace("@ T O D A Y S D A T E", Date.Now.ToString("MM/dd/yyyy")) sw.Write(content) sw.Close() Else

• Google index vs asp.net url routing

  - by vani

  I've made the change from querystring asp.net webforms application to an url routing one. Now I'm trying to let google know that there's a new set of urls to be aware of. The G has indexed 133 out of 179 new urls sent in sitemap.xml, but the site:mistral.hr command returns the old querystring version of the links. This could partly be so because I left the functionality of the old querystring version of the site(for backwards compatibility), and haven't done any 301 redirects(nor do I know how to achieve them in my shared hosting account). The old querystring and the new url routing both point to the same Default.aspx page.

• Base URL in ASP.net Master Pages with virtual Directories

  - by Ian

  Hi All, I have an ASP.net master page. In this master, I have all my css and javascript files defined. I also have a few images and a few buttons and hyperlinks. All the urls are all declared as relative ie "/scripts/ian.js" Everything works fine if this site is the root website, but I need it to work in a virtual directory. My problem is when I place this website in a virtual directory under a root site, all my links are pointing to the root site. so my links point to www.root.com/scripts/ian.js but it should be pointing to www.root.com/virtualDir/scripts/ian.js I thought the Base Href tag in the header would help, but so far it does not seem to be helping in anyway. All the links are still pointing to the root website when i hover over them. Any suggestions or ideas are welcome. Thanks

• in visual studio 2008, when I stop debugging an asp classic website visual studio always crashes

  - by yamspog

  We are running visual studio 2008 (with the service pack) and having troubles when we are debugging an asp classic website. We can attach to the w3p process and debug just fine. breakpoints work, we can view variable values. The difficulty arises when it comes time to detach or stop the debugger. Every time we take either approach (detach or stop the debugger) we get a series of crashes from Visual studio. Has anyone seen anything like this? Any suggestions on what to look at?

• NVelocity ASP.NET Examples

  - by Ben

  I'm looking to use NVelocity in my ASP.NET MVC application, not as a view engine, just for rendering some email templates. However, I cannot for the life of me get it to work. I have downloaded it from the castle project and followed the example at http://www.castleproject.org/others/nvelocity/usingit.html#step1 No matter what I try I don't seem to be able to load a template located in my site. The example suggests using the absolute path, which I have tried to no avail: Template t = engine.GetTemplate("/Templates/TestEmail.vm"); So please can someone give me two examples. One of loading a template located in the web site directory and secondly one parsing a string variable (as it is likely that my templates will be stored in a database). Many thanks Ben

• How to server-side cache ASP.NET custom HttpHandler response

  - by Joel

  I've got a custom HttpHandler in my ASP.NET application, that basically builds and returns a javascript object. I have no experience with server-side caching, and my (possibly incompetent) google searches aren't returning anything basic enough to get me started. Could anyone provide a very simple example to give me an idea of how to access and use the server-side cache from a custom HttpHandler, or, leave some links to get me started? Thanks a lot. Additional info: I'm on IIS 6, and my code-behind is in C# (although a VB example would work as well).

• How to page while maintaining the querystring values in ASP.Net Mvc 2

  - by Picflight

  I am using the pager provided by Martijin Boland to implementing paging in my Asp.Net Mvc 2 application. My form uses the GET method to send all parameters to the querystring, it is a search form with several form elements. <% using (Html.BeginForm("SearchResults", "Search", FormMethod.Get)) {%> On the SearchResults View I am trying to implement paging: <div class="pager"> <%= Html.Pager(Model.PageSize, Model.PageNumber, Model.TotalItemCount, new { Request.QueryString })%> </div> The Html.Pager has some overloads which I am not too clear on how to use. The Request.QueryString makes the querystring look like this: http://localhost:1155/Search/SearchResults?QueryString=Distance%3D10%26txtZip%3D%26cb&page=2 Should it not be like this? http://localhost:1155/Search/SearchResults?Distance=20&txtZip=10021&page=2

• ASP.NET MVC 2 validation using DTOs instead of domain entities

  - by Kevin Pang

  I'm struggling to mesh two best practices together: Using DataAnnotations + ModelBinding for validation in ASP.NET MVC 2 Using DTOs instead of domain entities when passing data via the ViewModel If I want to pass over DTOs instead of domain entities, then leveraging DataAnnotations + ModelBinding for validation would require me to specify validation attributes on my DTO classes. This results in a lot of duplicated work since multiple DTOs may hold overlapping fields with the same validation restrictions. This means that any time I change a validation rule in my domain, I have to go find all DTOs that correspond with that value and update their validation attributes.

• 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.

• ASP.Net MVC view unable to see HtmlHelper extension method

  - by larryq

  Hi everyone, We're going through an ASP.Net MVC book and are having trouble with using an extenstion method within our view. The Extension method looks like this: using System; using System.Runtime.CompilerServices; using System.Web.Mvc; namespace MvcBookApplication { public static class HtmlHelperExtensions { public static string JQueryGenerator(this HtmlHelper htmlHelper, string formName, object model); } } We use the extension method in our view like this: <%=Html.JQueryGenerator("createmessage", ViewData.Model)%> The problem is, that line of code says JQueryGenerator isn't a recognized method of HtmlHelper. I believe we've got the correct references set in the web project, but are there other things we can check? There's no using statement for views, is there?

• asp.net mvc: handling no-javascript

  - by Bala R

  Hello, I'm working on a asp.net mvc2 app. I have been using jquery to do various different things in all of my views. They are work from a regular browser quite well. But I'm trying to figure out a good way to get the functionality working with browsers with javascript disabled (like mobile browsers). Is there a way to define a whole different view for non javascript browsers? A specific example of what I'm trying to do is, I have a with it's onClick calling a javascript that does $.post() to a controller. What's a good way to make it, so, it works the way it works right now (doing ajax calls) with regular javascript-enabled browsers and it a also works with javascript-incapable browsers, doing a full postback ? Thanks
