  • DataAnnotations and Resources don't play nicely

    - by devlife
    I'm using dataannotations in an MVC2 app and am a little discouraged when trying to use RESX file resources for error messages. I've tried the following but keep getting the exception "An attribute [Required(ErrorMessage = Resources.ErrorMessages.Required)] [Required(ErrorMessageResourceName = Resources.ErrorMessages.Required, ErrorMessageResourceType = typof(Resources.ErrorMessages)] I keep getting that error message unless I replace ErrorMessageResourceName with "Required" instead of Resources.ErrorMessages.Required. Can anyone tell me if I'm doing this right?

  • Please help! request compression

    - by Naor
    Hi, I wrote an IHttpModule that compress my respone using gzip (I return a lot of data) in order to reduce response size. It is working great as long as the web service doesn't throws an exception. In case exception is thrown, the exception gzipped but the Content-encoding header is disappear and the client doesn't know to read the exception. How can I solve this? Why the header is missing? I need to get the exception in the client. Here is the module: public class JsonCompressionModule : IHttpModule { public JsonCompressionModule() { } public void Dispose() { } public void Init(HttpApplication app) { app.BeginRequest += new EventHandler(Compress); } private void Compress(object sender, EventArgs e) { HttpApplication app = (HttpApplication)sender; HttpRequest request = app.Request; HttpResponse response = app.Response; try { //Ajax Web Service request is always starts with application/json if (request.ContentType.ToLower(CultureInfo.InvariantCulture).StartsWith("application/json")) { //User may be using an older version of IE which does not support compression, so skip those if (!((request.Browser.IsBrowser("IE")) && (request.Browser.MajorVersion <= 6))) { string acceptEncoding = request.Headers["Accept-Encoding"]; if (!string.IsNullOrEmpty(acceptEncoding)) { acceptEncoding = acceptEncoding.ToLower(CultureInfo.InvariantCulture); if (acceptEncoding.Contains("gzip")) { response.AddHeader("Content-encoding", "gzip"); response.Filter = new GZipStream(response.Filter, CompressionMode.Compress); } else if (acceptEncoding.Contains("deflate")) { response.AddHeader("Content-encoding", "deflate"); response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress); } } } } } catch (Exception ex) { int i = 4; } } } Here is the web service: [WebMethod] public void DoSomething() { throw new Exception("This message get currupted on the client because the client doesn't know it gzipped."); } I appriciate any help. Thanks!

  • Get website's server from IP address

    - by Steven
    I have a function that returns a website's server when you enter the url for the site: private string GetWebServer() { string server = string.Empty; //get URL string url = txtURL.Text.Trim().ToLower(); if (!url.StartsWith("http://") && !url.StartsWith("https://")) url = "http://" + url; HttpWebRequest request = null; HttpWebResponse response = null; try { request = WebRequest.Create(url) as HttpWebRequest; response = request.GetResponse() as HttpWebResponse; server = response.Headers["Server"]; } catch (WebException wex) { server = "Unknown"; } finally { if (response != null) { response.Close(); } } return server; } I'd like to also be able to get a website's server from the IP address instead of the site's url. But if I enter an IP address, I get an error saying "Invalid URI: The format of the URI could not be determined." when calling WebRequest.Create(url). Does someone know how I can modify this to accomplish what I want?

  • jQuery Ajax (beforeSend and complete) working properly on FireFox but not on IE8 and Chrome

    - by Farhan Zia
    I am using jQuery ajax version 1.4.1 in my MVC application (though the issue I am discussing was same with the old jQuery version 3.2.1) as well, to check during customer registration if the username is already registered. As the user clicks on the "Check Availibility" button, I am showing a busy image in place of the check button (actually hiding the check button and showing the image) while checking the availibility on the server and then displaying a message. It is a Sync call (async: false) and I used beforeSend: and complete: to show and hide the busy image and the check button. This thing is working well on Firefox but in IE 8 and Chrome, neither the busy image appear nor the check button hides rather the check button remained pressed as the whole thing has hanged. The available and not available messages appear correctly though. Below is the code: HTML in a User Control (ascx): (i have replaced the angular braces with square below) [div id="available"]This Username is Available [div id="not_available"]This Username is not available [input id="txtUsername" name="txtUsername" type="text" size="50" /]  [button id="check" name="check" type="button"]Check Availability[/button] [img id="busy" src="/Content/Images/busy.gif" /] On the top of this user control, I am linking an external javascript file that has the following code: $(document).ready(function() { $('img#busy').hide(); $('div#available').hide(); $('div#not_available').hide(); $("button#check").click(function() { var available = checkUsername($("input#txtUsername").val()); if (available == "1") { $("div#available").show(); $("div#not_available").hide(); } else { $("div#available").hide(); $("div#not_available").show(); } }); }); function checkUsername(username) { $.ajax({ type: "POST", url: "/SomeController/SomeAction", data: { "id": username }, timeout: 3000, async: false, beforeSend: function() { $("button#check").hide(); $("img#busy").show(); }, complete: function() { $("button#check").show(); $("img#busy").hide(); }, cache: false, success: function(result) { return result; }, error: function(error) { $("img#busy").hide(); $("button#check").show(); alert("Some problems have occured. Please try again later: " + error); } }); }

  • Can't get FCKEditor to work in a virtual directory.

    - by AngryHacker
    I have a WebForm that contains the following definition for the FCKeditor: <FCKeditorV2:FCKeditor ID="txtBody" runat="server" BasePath="/fckeditor/" Height="480px" ToolbarSet="WebCal1" > </FCKeditorV2:FCKeditor> This works fine in my VS2008-based web application. However, when I deploy it to a Virtual Directory in IIS, it looks for the FCKEditor files (e.g. javascript, stylesheets, etc...) in the /fckeditor folder, not in the /MyVirtualDir/fkceditor. I've tried changing the BasePath to ~/fckeditor/, but then it won't work on my dev machine. What is the right way to go, so that the FCKEditor maps onto the right directory. In my project the fckeditor directory is right off the root.

  • Visual Studio ignore try catch - debug only

    - by Praesagus
    I think error handling is a good idea. :) When debugging it can get in the way - especially with nice user friendly messages. In VB6 I could just check a box for the compiler to ignore my error handling. I found the dialog that allows me to do something similar in VS, but it's about 10,000 check boxes instead of one - which is too many to change every time I want a production compilation. Is there a way to set VS up so when I am in debugging mode I get one set of conditions and when I am in production I get another? ...or is there just another method to handling errors and debugging more efficiently? Thanks

  • Element 'Chart' is not a known element - dotnetCHARTING

    - by Ryan
    Hi, I am using dotnetCHARTING: the dll is installed in the GAC and referenced in my web.config (all versions appear to match). The project has a reference to the dll. web.config: <add assembly="dotnetCHARTING, Version=5.3.3540.17054, Culture=neutral, PublicKeyToken=af2cd47db69d93bd"/> The site code compiles ok, but all aspx pages using the charting library complain that the Chart tag does not exist (warning that it might be a compile error). The aspx pages do not render the charts. Each page has a reference to the assembly: <%@ Register Assembly="dotnetCHARTING" Namespace="dotnetCHARTING" TagPrefix="dotnetCHARTING" %> Does anybody know what could be causing this? Thanks a lot for any help - I'm quite desperate to get this resolved. Ryan

  • jQuery .ajax() call to page method works in FF only when async is false

    - by Steve
    I'm calling a page method using .ajax() and it works in IE8 whatever the value of async is. However, in FF3.6, it only works with async set to false. When async is set to true, in Firebug, I just see status aborted. The page validates. I can work with async set to false, but any clues as to why FF can't work with async set to true? $("[id$='_www']").click(function() { var hhh = false; $.ajax({ async: false, cache: false, type: "POST", url: "/abc/def.aspx/jkl", contentType: "application/json; charset=utf-8", dataType: "json", data: "{ 'eee': '" + window.location.href.match(/\d{1,3}$/) + "', 'ttt': '" + $("[id$='_zzz']").val() + "' }", success: function(msg) { $("#ggg").html(msg.d); }, error: function(xhr, err) { hhh = true; } }); return hhh; });

  • BindAttribute, Exclude nested properties for complex types

    - by David Board
    I have a 'Stream' model: public class Stream { public int ID { get; set; } [Required] [StringLength(50, ErrorMessage = "Stream name cannot be longer than 50 characters.")] public string Name { get; set; } [Required] [DataType(DataType.Url)] public string URL { get; set; } [Required] [Display(Name="Service")] public int ServiceID { get; set; } public virtual Service Service { get; set; } public virtual ICollection<Event> Events { get; set; } public virtual ICollection<Monitor> Monitors { get; set; } public virtual ICollection<AlertRule> AlertRules { get; set; } } For the 'create' view for this model, I have made a view model to pass some additional information to the view: public class StreamCreateVM { public Stream Stream { get; set; } public SelectList ServicesList { get; set; } public int SelectedService { get; set; } } Here is my create post action: [HttpPost] [ValidateAntiForgeryToken] public ActionResult Create([Bind(Include="Stream, Stream.Name, Stream.ServiceID, SelectedService")] StreamCreateVM viewModel) { if (ModelState.IsValid) { db.Streams.Add(viewModel.Stream); db.SaveChanges(); return RedirectToAction("Index", "Service", new { id = viewModel.Stream.ServiceID }); } return View(viewModel); } Now, this all works, apart from the [Bind(Include="Stream, Stream.Name, Stream.ServiceID, SelectedService")] bit. I can't seem to Include or Exclude properties within a nested object.

  • nHibernate strategies in a web farm

    - by Pete Nelson
    Our current project at work is a new MVC web site that will use a WCF service primarily to access a 3rd party billing system via a web service as well as a small SQL database for user personalization. The WCF service uses nHibernate for the SQL database. We'd like to implement some sort of web farm for load balancing as well as failover and maintenance. I'm trying to decide the best way to handle nHibernate's caching and database concurrency if there are multiple WCF services running. Some scenarios I've been thinking about... 1) Multiple IIS servers, one WCF server. With this setup, the WCF server would be a single point of failure, but there would be no issues with nHibernate caching or database concurrency. 2) Multiple IIS servers, each with it's own WCF service. This removes a single point of failure, but now nHibernate on one machine would not know about database changes done by another machine. Some solutions to number 2 would be to use an IStatelessSession so we're not doing any caching and nHibernate is always fetching directly from the database. This might be the most feasible as our personalization database has very few objects in it. I'm also considering a 2nd-level cache such as memcached or Velocity, but it may be overkill for this system. I'm putting this out there to see if anyone has experience doing this sort of architecture and to get some ideas for a solution. Thanks!

  • Why can't I debug from Visual Studio 2005 after installing IE8?

    - by tjrobinson
    I've just installed IE8 (final) and restarted. I can no longer debug Web Application Projects using Visual Studio 2005 on Windows Server 2003 Enterprise R2. I get the message "Internet Explorer cannot display the webpage" and then WebDev.WebServer.exe quits with no visible error message and nothing in the Event Viewer. Does anyone have any ideas? Things that haven't helped: Adding localhost to trusted sites Changing the port to 8080 or 80 Checking my hosts file (it's just got 127.0.0.1 localhost in it) Things that have helped a bit: Running (not debugging) with CTRL-F5, which works fine (unless you need to debug) Changing the default Visual Studio browser to Firefox, which allows me to debug My hosts file contains: # Copyright (c) 1993-1999 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost

  • Generic wrapper for System.Web.Caching.Cache functions

    - by David Neale
    I've created a generic wrapper for using the Cache object: public class Cache<T> where T : class { public Cache Cache {get;set;} public CachedKeys Key {get;set;} public Cache(Cache cache, CachedKeys key){ Cache = cache; Key = key; } public void AddToCache(T obj){ Cache.Add(Key.ToString(), obj, null, DateTime.Now.AddMinutes(5), System.Web.Caching.Cache.NoSlidingExpiration, System.Web.Caching.CacheItemPriority.Normal, null); } public bool TryGetFromCache(out T cachedData) { cachedData = Cache[Key.ToString()] as T; return cachedData != null; } public void RemoveFromCache() { Cache.Remove(Key.ToString()); } } The CachedKeys enumeration is just a list of keys that can be used to cache data. The trouble is, to call it is quite convuluted: var cache = new Cache<MyObject>(Page.Cache, CachedKeys.MyKey); MyObject myObject = null; if(!cache.TryGetFromCache(out myObject)){ //get data... cache.AddToCache(data); //add to cache return data; } return myObject; I only store one instance of each of my objects in the cache. Therefore, is there any way that I can create an extension method that accepts the type of object to Cache and uses (via Reflection) its Name as the cache key? public static Cache<T> GetCache(this Cache cache, Type cacheType){ Cache<cacheType> Cache = new Cache<cacheType>(cache, cacheType.Name); } Of course, there's two errors here: Extension methods must be defined in a non-generic static class The type or namespace name 'cacheType' could not be found This is clearly not the right approach but I thought I'd show my working. Could somebody guide me in the right direction?

  • Using UpdatePanels inside of a ListView

    - by Jim B
    Hey everyone, I'm wondering if anybody has run across something similar to this before. Some quick pseudo-code to get started: <UpdatePanel> <ContentTemplate> <ListView> <LayoutTemplate> <UpdatePanel> <ContentTemplate> <ItemPlaceholder /> </ContentTemplate> </UpdatePanel> </LayoutTemplate> <ItemTemplate> Some stuff goes here </ItemTemplate> </ListView> </ContentTemplate> </UpdatePanel> The main thing to take away from the above is that I have an update panel which contains a listview; and then each of the listview items is contained in its own update panel. What I'm trying to do is when one of the ListView update panels triggers a postback, I'd want to also update one of the other ListView item update panels. A practical implementation would be a quick survey, that has 3 questions. We'd only ask Question #3 if the user answered "Yes" to Question #1. When the page loads; it hides Q3 because it doesn't see "Yes" for Q1. When the user clicks "Yes" to Q1, I want to refresh the Q3 update panel so it now displays. I've got it working now by refreshing the outer UpdatePanel on postback, but this seems inefficient because I don't need to re-evaluate every item; just the ones that would be affected by the prerequisite i detailed out above. I've been grappling with setting up triggers, but i keep coming up empty mainly because I can't figure out a way to set up a trigger for the updatepanel for Q3 based off of the postback triggered by Q1. Any suggestions out there? Am I barking up the wrong tree?

  • Webservice complex types and class inheritance

    - by pygorex1
    Using the following Webservice definition using aClientArgs as a complex type: [System.Web.Script.Services.ScriptService] public class Controller : System.Web.Services.WebService { [WebMethod] public void save_client(aClientArgs client) { // Save client data } } Then defining aClientArgs as a sub-class: public class aArgs { public string id = null; public string name = null; } public class aClientArgs : aArgs { public string address = null; public string website = null; } Returns the following WSDL fragment for the save_client args: <save_client xmlns="http://tempuri.org/"> <client> <address>string</address> <website>string</website> </client> </save_client> When I'm expecting the following: <save_client xmlns="http://tempuri.org/"> <client> <id>string</id> <name>string</name> <address>string</address> <website>string</website> </client> </save_client> So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?

  • Using PostRequestHandlerExecute, Flush and Close to clean up after a request - why is this bad?

    - by Erwin
    After some requests I need to clean up after the user - by calling a remote web service to release some resources if I guess the user doesn't need them anymore. It is ok to leave them hanging and letting them time out on the other server, but the polite thing to do is to inform it that I do not need them anymore. I do not want to waste the users time waiting for cleaning - so I tried to find place to put it. First I tried Application_EndRequest, but I needed something later. Then I found PostRequestHandlerExecute which seemed like a nice place, but I still need a Flush and Close to release the connection to the user. Protected Sub Application_PostRequestHandlerExecute(ByVal sender As Object, ByVal e As System.EventArgs) Response.Flush() Response.Close() ' Simulation of clean up activity: System.Threading.Thread.Sleep(4000) ' Really a couple of web service calls End Sub Is there some other place I could put these lengthy clean up routines?

  • Code Access Security - Basics and Example

    - by jobless-spt
    I was going through this link to understand CodeAccessSecurity: http://www.codeproject.com/KB/security/UB_CAS_NET.aspx It's a great article but it left me with following questions: If you can demand and get whatever permissions you want, then any executable can get Full_Trust on machine. If permissions are already there, then why do we need to demand those? Code is executing on Server, so the permissions are on server not on client machine? Article takes an example of removing write permissions from an assembly to show security exception. Though in real world, System.IO assembly (or related classes) will take care of these permissions. So is there a real scenario where we will need CAS?

  • Allow user to download file and filename on client defaults to no extension

    I want the user to be able to download a file from a page and have the filename extension in the Save As dialog box to be defaulted to nothing. This is the code I'm using: Response.ContentType = "text/plain" Response.AppendHeader("content-disposition", "attachment; filename=FILE") Response.WriteFile("C:\Temp\FILE") Response.End() FILE is the actual file. It is saved on the server without any extension. Currently, the "Save As Type" drop down list in the dialog defaults to "Text Document". How can I make it so that it defaults to "All Files"?
