  • Interpreting w3wp.exe thread-infos, does mscorwks.dll!StrongNameErrorInfo+0x7688 has a negative impa

    - by Robert
    I am trying to interpret the meaning of "mscorwks.dll!StrongNameErrorInfo+0x7688". I guess it means, that the assembly loaded by the mscorworks.dll has no StrongName? If yes, does this have any negative impact for a web application? Is it safe to assume that the thread count of 107 means, that web application has needed a maximum of 107 concurrent threads to handle incoming requests?

If I leave dropdownlist and try to insert wrong date I get following error: System.InvalidOperationException: The ViewData item with the key 'CategoryId' is of type 'System.Int32' but needs to be of type 'IEnumerable'. If I enter correct date than the article is properly inserted. There's one other thing that's confusing me... For example, if I try manually add the categoyID: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Article article) { if (ModelState.IsValid) { try { // TODO: Add insert logic here // Manually add category value article.CategoryID = 1; articleRepository.Add(article); articleRepository.Save(); return RedirectToAction("Index"); } catch { return View(article); } } else { return View(article); } } ..I also get the above error. There's one other thing I noticed. If I add partial class Article, when returning to articleRepository.cs I get error that 'Article' is an ambiguous reference between 'CMS.Models.Article' and 'CMS.Model.Article' Any thoughts on this one?

  • Intermittent PolicyException: Execution permission cannot be acquired.

    - by Aaron Maenpaa
    We are intermittently seeing the following exception shortly after an App Pool recycle in an ASP.NET application: System.Configuration.ConfigurationErrorsException: Could not load file or assembly 'Microsoft.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Failed to grant permission to execute. (Exception from HRESULT: 0x80131418) ---> System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Failed to grant permission to execute.

We're running on ASP.NET 3.5 on Windows Server 2008. This seems to happen in batches affecting some but not all of sites on the same App Pool. We have a large number of sites all running the same code. Once a site has failed to load a DLL it throws up a Yellow Screen of Death until the next App Pool recycle. We haven't been able to reproduce this behavior and the sites seem to work fine for days or weeks at a time (and many App Pool recycles) before failing. Has anybody else seen similar behavior? Update: We've tried reproducing the failure by setting up a few hundred sites and writing a script to hit them repeatedly while recycling the App Pool once every couple of minutes and were unable to accomplish much other than loading down the server's CPU for a few days straight. We then tried messing (locking one of the DLLs, changing the file permissions) with the copies of the DLLs that ASP.NET makes and managed to reproduce similar behavior but not the same exception. Does anybody have any ideas on how to adjust the security policy to get it to throw a System.Security.Policy.PolicyException: Execution permission cannot be acquired. when loading a specific DLL?

  • Injecting jms resource in servlet & best practice for MDB

  • ASP.NET UserControl OnError

    - by michl86
    UserControls in ASP.NET (4.0) inherit from System.Web.UI.UserControl. VisualStudio intellisense suggest OnError as valid override of TemplateControl. At runtime .NET ignores this error handling. Only the OnError at Page-Level gets invoked. Did i miss anything or is there a design issue? public partial class Sample : System.Web.UI.UserControl { protected override void OnError(EventArgs e) { // Never reach ;o) base.OnError(e); } }

  • Server side Xforms form validation and integration into ASP.NET

    - by Nigel
    I have recently been investigating methods of creating web-based forms for an ASP.NET web application that can be edited and managed at runtime. For example an administrator might wish to add a new validation rule or a new set of fields. The holy grail would provide a means of specifying a form along with (potentially very complex) arbitrary validation rules, and allocation of data sources for each field. The specification would then be used to update the deployed form in the web application which would then validate submissions both on the client side and on the server side. My investigations led me to Xforms and a number of technologies that support it. One solution appears to be IBM Lotus Forms, but this requires a very large investment in terms of infrastructure, which makes it infeasible, although the forms designer may be useful as a stand-alone tool for creating the forms. I have also discounted browser plug-ins as the form must be publicly visible and cross-browser compliant. I have noticed that there are numerous javascript libraries that provide client side implementations given an Xforms schema. These would provide a partial solution but server side validation is still a requirement. Another option seems to involve the use of server side solutions such as the Java application Orbeon. Orbeon provides a tool for specifying the forms (although not as rich as Lotus Forms Designer), but the most interesting point is that it can translate an XForms schema into an XHTML form complete with validation. The fact that it is written in Java is not a big problem if it is possible to integrate with the existing ASP.NET application. So my question is whether anyone has done this before. It sounds like a problem that should have been solved but is inherently very complex. It seems possible to use an off-the-shelf tool to design the form and export it to an Xforms schema and xhtml form, and it seems possible to take that xforms schema and form and publish it using a client side library. What seems to be difficult is providing a means of validating the form submission on the server side and integrating the process nicely with .NET (although it seems the .NET community doesn't involve themselves with XForms; please correct me if I'm wrong on this count). I would be more than happy if a product provided something simple like a web service that could validate a submission against a schema. Maybe Orbeon does this but I'd be grateful if somebody in the know could point me in the right direction before I research it further. Many thanks.

  • Ndepend CQL to query types out of assembly wildcard

    - by icelava
    In order to determine what low-level framework types a web application is directly using, one has to define each and every assembly involved. SELECT TYPES FROM ASSEMBLIES "Company.System.Framework", "Company.System.Framework.ReferenceLookup", "Company.System.Framework.Web", "Company.System.Framework.Security", "Company.System.Framework.Logging", "Company.System.Framework.DMS" WHERE IsDirectlyUsedBy "WebAssembly" I cannot find any syntax to wildcard the list of assemblies. Is there no way to shortcut this? We have a lot of framework level assemblies. i.e. Company.System.Framework.*

  • msbuild TransformWebConfig task - doesn't work for App.configs?

    - by Jeff D
    I have a windows service that will need to have the same kind of transformations that the web.configs would use, but VS 2010 doesn't seem to support that. I've tried manually adding the App.Release.Config files, and then using msbuil [PROJ] /T:TransformWebConfig /p:Configuration=Release but no transformation is performed. I got a TransformWebConfig folder createed in my obj subdirectory, but that's it. Is this thing hardcoded to only work with web.configs?

  • ScriptManager ServiceReference loading animation

    - by TesterTurnedDeveloper
    I'm using a ScriptManager / ServiceReference to call as ASMX from client side code, just like the Calling Web Services from Client Script in ASP.NET AJAX example. Is there an easy way to show/hide a loading animation when I'm fetching data from the web service? I could show it when I call the service, and hide it in the callback. Is there an event I can attach to? I like the way JQuery has Ajax events for this sort of thing.

  • Entrepreneur Needs Programmers, Architects, or Engineers?

    - by brand-newbie
    Hi guys (Ladies included). I posted on a related site, but THIS is the place to be. I want to build a specialized website. I am an entrepreneur and refining valuations now for venture capitalsists: i.e., determining how much cash I will need. I need help in understanding what human resources I need (i.e., Software Programmers, Architects, Engineers, etc.)??? Trust me, I have read most--if not all--of the threads here on the subject, and I can tell you I am no closer to the answer than ever. Here's my technology problem: The website will include (2) main components: a search engine (web crawler)...and a very large database. The search engine will not be a competitor to google, obviously; however, it "will" require bots to scour the web. The website will be, basically, a statistical database....where users should be able to pull up any statistic from "numerous" fields. Like any entrepreneur with a web-based vision, I'm "hoping" to get 100+ million registered users eventually. However, practically, we will start as small as feasible. As regards the technology (database architecture, servers, etc.), I do want quality, quality, quality. My priorities are speed, and the capaility to be scalable...so that if I "did" get globally large, we could do it without having to re-engineer anything. In other words, I want the back-end and the "infrastructure" to be scalable and professional....with emphasis on quality. I am not an IT professional. Although I've built several Joomla-based websites, I'm just a rookie who's only used minor javascript coding to modify a few plug-ins and components. The business I'm trying to create requires specialization and experts. I want to define the problem and let a capable team create the final product, and I will stay totally hands off. So who do you guys suggest I hire to run this thing? A software engineer? I was thinking I would need a "database engineer," a "systems security engineer", and maybe 2 or 3 "programmers" for the search engine. Also a web designer...and maybe a part-time graphic designer...everyone working under a single software engineer. What do you guys think? Who should I hire?...I REALLY need help from some people in the industry (YOU guys) on this. Is this project do-able in 6 months? If so, how many people will I need? Who exactly needs to head up this thing?...Senior software engineer, an embedded engineer, a CC++ engineer, a java engineer, a database engineer? And do I build this thing is Ruby or Java?

  • SPWeb.Url returns wrong URL

    - by Jason
    I have a web application in SharePoint that has been extended to another zone (Extranet). The access URL for the default zone is http ://server1, and the URL for the extranet zone is https: //www.server1.com. Now, when I access the site via the extranet zone, I find that SPContext.Current.Web.Url returns http ://server1. I would have expected https ://www.server1.com, since that's how I'm accessing the site. What am I doing wrong?

  • Can one instance of a WCF service pass work on to another instance where this 2nd instance would rep

    - by Matt
    Let's say I have 2 instances of the same web services. Is there a way that I can have the second instance of the web service perform a task at the behest of the first instance of the WCF service and reply directly to the original requester? I could code this and include logic in WCF-A to contact WCF-B under the right conditions and then passback the result, but returning to the requester directly from WCF-B would be easier. Also, I made a handy dandy chart.

  • Django app that can provide user friendly, multiple / mass file upload functionality to other apps

    - by hopla
    Hi, I'm going to be honest: this is a question I asked on the Django-Users mailinglist last week. Since I didn't get any replies there yet, I'm reposting it on Stack Overflow in the hope that it gets more attention here. I want to create an app that makes it easy to do user friendly, multiple / mass file upload in your own apps. With user friendly I mean upload like Gmail, Flickr, ... where the user can select multiple files at once in the browse file dialog. The files are then uploaded sequentially or in parallel and a nice overview of the selected files is shown on the page with a progress bar next to them. A 'Cancel' upload button is also a possible option. All that niceness is usually solved by using a Flash object. Complete solutions are out there for the client side, like: SWFUpload http://swfupload.org/ , FancyUpload http://digitarald.de/project/fancyupload/ , YUI 2 Uploader http://developer.yahoo.com/yui/uploader/ and probably many more. Ofcourse the trick is getting those solutions integrated in your project. Especially in a framework like Django, double so if you want it to be reusable. So, I have a few ideas, but I'm neither an expert on Django nor on Flash based upload solutions. I'll share my ideas here in the hope of getting some feedback from more knowledgeable and experienced people. (Or even just some 'I want this too!' replies :) ) You will notice that I make a few assumptions: this is to keep the (initial) scope of the application under control. These assumptions are of course debatable: All right, my idea's so far: If you want to mass upload multiple files, you are going to have a model to contain each file in. I.e. the model will contain one FileField or one ImageField. Models with multiple (but ofcourse finite) amount of FileFields/ ImageFields are not in need of easy mass uploading imho: if you have a model with 100 FileFields you are doing something wrong :) Examples where you would want my envisioned kind of mass upload: An app that has just one model 'Brochure' with a file field, a title field (dynamically created from the filename) and a date_added field. A photo gallery app with models 'Gallery' and 'Photo'. You pick a Gallery to add pictures to, upload the pictures and new Photo objects are created and foreign keys set to the chosen Gallery. It would be nice to be able to configure or extend the app for your favorite Flash upload solution. We can pick one of the three above as a default, but implement the app so that people can easily add additional implementations (kinda like Django can use multiple databases). Let it be agnostic to any particular client side solution. If we need to pick one to start with, maybe pick the one with the smallest footprint? (smallest download of client side stuff) The Flash based solutions asynchronously (and either sequentially or in parallel) POST the files to a url. I suggest that url to be local to our generic app (so it's the same for every app where you use our app in). That url will go to a view provided by our generic app. The view will do the following: create a new model instance, add the file, OPTIONALLY DO EXTRA STUFF and save the instance. DO EXTRA STUFF is code that the app that uses our app wants to run. It doesn't have to provide any extra code, if the model has just a FileField/ImageField the standard view code will do the job. But most app will want to do extra stuff I think, like filling in the other fields: title, date_added, foreignkeys, manytomany, ... I have not yet thought about a mechanism for DO EXTRA STUFF. Just wrapping the generic app view came to mind, but that is not developer friendly, since you would have to write your own url pattern and your own view. Then you have to tell the Flash solutions to use a new url etc... I think something like signals could be used here? Forms/Admin: I'm still very sketchy on how all this could best be integrated in the Admin or generic Django forms/widgets/... (and this is were my lack of Django experience shows): In the case of the Gallery/Photo app: You could provide a mass Photo upload widget on the Gallery detail form. But what if the Gallery instance is not saved yet? The file upload view won't be able to set the foreignkeys on the Photo instances. I see that the auth app, when you create a user, first asks for username and password and only then provides you with a bigger form to fill in emailadres, pick roles etc. We could do something like that. In the case of an app with just one model: How do you provide a form in the Django admin to do your mass upload? You can't do it with the detail form of your model, that's just for one model instance. There's probably dozens more questions that need to be answered before I can even start on this app. So please tell me what you think! Give me input! What do you like? What not? What would you do different? Is this idea solid? Where is it not? Thank you!
