  • ASP.NET MVC: Making routes/URLs IIS6 and IIS7-friendly

    - by Seb Nilsson
    I have an ASP.NET MVC-application which I want deployable on both IIS6 and IIS7 and as we all know, IIS6 needs the ".mvc"-naming in the URL. Will this code work to make sure it works on all IIS-versions? Without having to make special adjustments in code, global.asax or config-files for the different IIS-versions. bool usingIntegratedPipeline = HttpRuntime.UsingIntegratedPipeline; routes.MapRoute( "Default", usingIntegratedPipeline ? "{controller}/{action}/{id}" : "{controller}.mvc/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); Update: Forgot to mention. No ISAPI. Hosted website, no control over the IIS-server.

  • Adding Images to an ASP .Net Chart Control

    - by wali
    Hello all! I'm not sure if I titled the question correctly so it would be better if I explained what I'm trying to do. I am using the ASP .Net Chart Control to create a line chart showing numbers of trouble calls based on date. What I would like to do is implement a way of annotating the chart with data whereas if there was a spike in trouble calls a line, or asterisk, etc would direct the viewer to "read notes below for an explanation for why the numbers spiked here". From the samples for the chart control there is a way you can add a bitmap to the chart, however I don't see how that will be effective here because the explanations will come dynamically from a database. If anyone's done something like this or has some guidance I'd appreciate it. Thanks!

    I have the following inside a content place holder in my asp .net pages: <style type="text/css"> #sortable1 { list-style-type: none; margin: 0; padding: 0; zoom: 1; } #sortable1 li { margin: 3px; padding: 3px; width: 90%; border: 1px solid #000000; background: #000000; color: #FFFFFF; } #sortable1 li.highlightWorkflow { background: #FFFF00; color: #000000; } </style> I would ideally like to swap the #00000's for values held on the page, maybe in hidden fields. Is this possible?

  • ASP.NET forgets dlls in bin directory

    - by Timothy Strimple
    We have a plugin system on a WCF service that checks libraries placed in the bin folder for certain assembly level attributes and loads them. This allows customization of certain service calls based on which client is making the call. This works great most of the time. However, sometimes it seems to lose the dll, which causes the service to revert back to the default implementation for every client. The solution so far has been to just move the dll file out of the bin folder, and back in. This causes asp.net to pick up the file and customizations start working again. I'm at a loss for why the assembly is getting missed like that after a certain amount of time. Any ideas as to what might be causing this?

  • ASP.NET MVC - ASPX with non-default constructor

    - by bh213
    Is it possible for a ASPX view (in ASP.NET MVC) to have non-default constructor AND use this constructor when creating this view? Example - Page will inherit from this class: public class ViewPageWithHelper<TModel> : System.Web.Mvc.ViewPage<TModel> where TModel : class { public ViewPageWithHelper(Helpers helpers) { Helpers = helpers; } protected Helpers Helpers { get; private set; } } ASPX view: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="MyInjectedViewPage<MyModel>" %> <% Helpers.XXXX %> Now, I'd like to inject Helpers into view somehow - automatically. Ideas?

  • Comet with ASP.NET AsyncHttpHandlers

    - by Sumit
    I am implementing a comet using AsyncHttpHandlers in my current asp.net application. According to my implementation client initially sends Notification Hook request to server (with its user id) on AsyncHttpHandler, and on server side I maintain a Global (Application level) dictionary of userid(key) and IAynsResult (value). So when ever a request is received to send notification to a user I just pick the matching IAsyncResult from the Global Dictionary and send response to the client user. My concern is, is maintaing a Dictionary of Userid and IAsyncResult at Application level a good design? I feel it will put a lot of load on the server, at the time of high traffic. Is there any other way I can achieve the comet. or what will be the good design to achieve comet for high traffic scenarios.

  • Asp.net cached objects staying in memory

    - by GordonB
    I have a asp.net web forms app that uses System.Web.Caching.Cache to cache xml data from a number of web services for 2 hours. webCacheObj.Remove(dataCacheKey) webCacheObj.Insert(dataCacheKey, dataToCache, Nothing, DateTime.Now.AddHours(2), Nothing) Every 90 minutes a Microsoft Search Server hits a particular (spider) page which calls the code to put the objects into the cache. The issue i have is that over a period of time, the memory usage of the application grows exponentially. Lets say that in a week, the memory usage of the application pool grows to over 1gb. I'm using IIS7 and no application pool recycling is currently enabled.

  • Debugging ASP.NET Session State server issues

    - by Cleggy
    We have an application that runs over load balanced server instances, and therefore is configured to use the ASP.NET session state service, which is running on one of our DB servers. While both instances of our app can successfully connect to the state server, changes in session state data are not being reflected across both of them. FI, If I call Session.Add('SomeKey', SomeData) on Server A, this is not being reflected if I then try to access Session['SomeKey'] on Server B. Session.SessionID returns the same value on both servers, and I have checked that they are both using the same validationkey and decryptionkey values configured in the machinekey section of machine.config. I even tried specifying these values in the apps web.config. What other things should I be looking out for which may be causing these symptoms, and what steps can people recommend to help debug this issue?

  • Converting ASP.NET MVC to n-Tiered Architecture

    - by Jeff
    I just built an application using ASP.NET MVC. The programmers at my company want to build all future modules using n-Tiered (Presentation Layer, Business Logic Layer, Data Access Layer) architecture. I am not the programmer and need to know why this makes sense? Do I have to completely rewrite the entire code or can it be converted? We are building an HRIS system with Business Intelligence. Somebody please explain why or why not this approach does or does not make sense.

  • asp.net 3.5 on windows 2000

    - by SiC
    Hi, I am trying to get an ASP.net 3.5 site to run on a windows 2000 machine (not my idea!!!) but am having some problems. I have been working through copying required dlls from C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5 into my app bin directory. This succesfully got me past the "assembly not found" errors. However, I am now getting the error: "Compiler executable file csc.exe cannot be found". Does anyone know how I can fix this? It is primarily LINQ functionality I am looking to utilise. Many thanks!!

  • ASP.NET Ajax Error: Sys.WebForms.PageRequestManagerParserErrorException

    - by Phil Bennett
    My website has been giving me intermittent errors when trying to perform any Ajax activities. The message I get is Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' So its obviously some sort of server timeout or the server's just returning back mangled garbage. This generally, unfortunately not always, happens when the site has been idle for a while. Anybody else been able to overcome this? Thanks

  • Using ASP.Net 4.0 for new Dev projects

    - by JBeckton
    I am currently in the early stages of developing a couple web applications, I have not written any code yet as I am still just gathering requirements and scoping things out. I want to target ASP.Net 4.0 winforms as the platform for these apps but I want to make sure there are no glaring issues with this new version before I commit. I understand that if I was porting an existing app from 2.0, 3.5 to 4.0 there may be issues but I am starting from scratch on these projects and plan to write these apps to support the new features of 4.0. Should I wait for the first service pack to come out? Just seems like more work to start with 3.5 now only to go back through and tweak things for 4.0 in just a few months or even before I finish the app. Our servers are Win 2K3 with IIS6 and MS SQL 2000, Should I expect any problems with VS 2010 and MS SQL 2000 in regards to Linq to SQL and EF?

  • Access ASP.NET control using javascript

    - by user3036965
    I have a basic javascript function like this which works as I am able to dynamically change the textbox in a javascript method at runtime. function MyTst(pVal2) { var x = document.getElementById('<%=myImage.ClientID%>'); x.src = "/images/write.gif"; } In the above code I need to be generic. So replace '<%=myImage.ClientID%' with the input param to my method which in this instance is called pVal2 and contains the asp.net server control image id. Can anyone advise on an approach to do this. I've tried lots of things and just cant seem to get it working. Thanks for any advice.

  • How to restructure ASP.NET application

    - by Ram
    Hi, I have a sample ASP.NET application. The appliaction was developed as POC and not following any design and architectural standards. Now I want to restructure the application. I can see some of the business logic and controls can be reused in future, such as login control. I have two options for restructuring I create a Utility DLL that will contain all such resusable code and another DLL that will contain all controls that can be reused. I will create a separeate DLL for each type which can be reused e.g. Login control. Which option is more better. Although I feel option 1 is good, but I need suggestion from experts.

  • Microsoft 2003 DNS sometimes cant query for some A pointers when their TTL expires

  • Windows 2012 Server: Enable .NET 3.5

    - by Meengla
    I have a Windows 2012 Server which needs .NET 3.5 installed. For background info/solutions, please see this: http://sqlblog.com/blogs/sergio_govoni/archive/2013/07/13/how-to-install-netfx3-on-windows-server-2012-required-by-sql-server-2012.aspx I have tried this but it doesn't work for me. Here is what I am trying: Using a Windows 2012 ISO file, 'mount' on the 2012 Server as 'D' drive and then tried both GUI and Command prompt. In case of GUI, I specified the 'alternate source' path to the D drive's 'source/sxs folder but that failed without giving enough info. In case of the command prompt, here is what's happening: dism /online /enable-feature /featurename:NetFx3 /source:d:\sources\sxs I get error: Installed but Parent feature not enabled. So I tried another approached: dism /online /enable-feature /featurename:NetFx3 /all /source:d:\sources\sxs the above command, per http://blogs.technet.com/b/askcore/archive/2012/05/14/windows-8-and-net-framework-3-5.aspx is supposed to enable parent elements; but running this I get error like 'source not found'. Is there some error in my second command? What else I could do? This is Windows 2012 Server Standard edition. Thanks!

  • .NET 3.5 installation comes up with Error 0x800F0906, then 0x800F0081F using dism

    - by Austin Meadows
    I've recently tried installing .NET 3.5 for an application on Windows 8.1. I used the OS's popup thing to download/install .NET 3.5 and always get error code 0x800F0906. Upon further research, I found I would have to pop in my Windows 8 CD and install it with this command, where "E:\" is where my CD is mounted: Dism /online /enable-feature /featurename:NetFx3 /All /Source:E:\sources\sxs /LimitAccess This and any derivative of it (e.g., removing /LimitAccess) has not worked for me and has either given me the same error code (0x800F0906) or a different one, 0x800F0081F. I've even copied the sxs folder to my hard drive, just in case something was going on with the CD Drive, only to have the same results. In that case, I used this command line: Dism /online /enable-feature /featurename:NetFx3 /All /Source:C:\dotnet35 /LimitAccess I find this surreal because in both cases, the files are indeed there but the program thinks it's not. Here's the CBS.log file. Any ideas on how to fix this? Any help is very appreciated :) EDIT: I now have a proper dism.log file, I'm not sure what happened to the last one or why it did that. Here's the link to the new log file. It's interesting to note that it doesn't recognize some of the commands in the script such as "featurename" or "source".
