  • How can I create and manage a multi-tenant ASP MVC application

    - by Wizzarding
    Hi, I want to create a multi-tenant application that uses the hostname to determine the customer. For example: CustomerOne.myapp.com AnotherCo.myapp.com AndOneMore.myapp.com ... I can do the database and security side with no problems, I can also get the hostname from the URL, but what I am struggling to find out is how to create the basic plumbing that would allow a new customer to sign up online, provide their company name, and for the application to create the new URL, ready to be used straight away. Can anyone help? Thanks, Rob.

  • Alternatives to web.config files in ASP.NET

    - by Ben Aston
    In my experience, web.config files are widely reviled. In particular, I have found them difficult to manage when you have multiple environments to support, and fiddly to update due to the lack of validation at update-time and the verbosity of XML. What are the alternatives?

  • The speed of .NET in numerical computing

    - by Yin Zhu
    In my experience, .net is 2 to 3 times slower than native code. (I implemented L-BFGS for multivariate optimization). I have traced the ads on stackoverflow to http://www.centerspace.net/products/ the speed is really amazing, the speed is close to native code. How can they do that? They said that: Q. Is NMath "pure" .NET? A. The answer depends somewhat on your definition of "pure .NET". NMath is written in C#, plus a small Managed C++ layer. For better performance of basic linear algebra operations, however, NMath does rely on the native Intel Math Kernel Library (included with NMath). But there are no COM components, no DLLs--just .NET assemblies. Also, all memory allocated in the Managed C++ layer and used by native code is allocated from the managed heap. Can someone explain more to me? Thanks!

  • asp.net MVC Partial Views how to initialise javascript

    - by Simon G
    Hi, I have an edit form that uses an ajax form to submit to the controller. Depending on the data submitted I redirect the user to one of two pages (by returning a partial view). Both pages rely on javascript/jquery and neither use anything common between the pages. What is the best way to initialise these javascripts on each page? I know there is the AjaxOption OnComplete but both pages are quite dynamic depending on the Model passed and I would rather keep the javascript for both pages seperate rather than having a common method. Thanks

  • ASP.NET Nested Repeater Accessing elements

    - by Rich
    I have a list of Accommodation objects bound to a Repeater, and then a nested Repeater which has the various attendee groups listed [e.g. Default, Seniors, Juniors]. This is all output fine, with the values displayed as LinkButtons, which when clicked gets sent to a code-behind event handler. Here is an example of the output to give you a picture [with some er... interesting attendee group names]: In the event handler, I test the object parameter to see which Repeater has been sent, as the outer repeater's links can also be clicked [so the Accommodation would be set, but no Attendee Group]. Is there a way to get a HiddenField from the outer RepeaterItem that contains the currently clicked inner repeater's LinkButton? E.g. From the image, I click the Attending link in the Women section. So the EventArgs via FindControl can get me the hidden field which contains the Attendee Group's ID, which is good, but I also need the Accommodation ID [to know whether it was either Wimbledon Hotel Inn or New Acc]

  • References between ASP.NET web applications.

    - by mcoolbeth
    I have a Visual Studio solution containing two web applications. I would like the first to depend on the second (pages in the first may contain links to, or possibly post to pages in the second). Furthermore, I would like to be able to launch the first project on a development server (standard debugging procedure for web apps in VS) and have the references to the second project be fully functional. Does anyone know the best way to achieve this? Thanks.

  • Asp.Net MVC 2 Client validation implementation for Enterprise Library Validation Block

    - by er-v
    Hello to everybody. I've found a very good article about how to use EntLib Validation Block for server validation in MVC 2. But as there pointed out The current design of EntLib’s Validation Application Block uses the Composite pattern; that is, when we ask for validation for an object, it returns back a single validator object that contains a list of all the validation work to be done. While this is very convenient from a normal usage scenario, the unfortunate side-effect is that we can’t “peek inside” to see what the individual validations are that it’s doing, and therefore can’t generate the appropriate client-side validation hints. So how is it possible to implement client side validation for EntLib? Is there work around?

  • Stack calling convention between .NET & C on WinCE 6.0

    - by bernard
    Hi there. I'm porting a DLL written in C from WinCE 5.0 to WinCE 6.0 on an ARM target. This DLL is called by a .NET software. On WinCE5.0, everything runs fine. On WinCE6, I have the following problem: on InitInstance() of my DLL, I can call anything without problem (for example MessageBox()) or uses recursivity. Passed that point, the DLL is called by .NET code. And then it fails: even the arguments passed by .NET code seem weird. I can call MessageBox() once, but I can't call a function that calls MessageBox() and then that calls itself: recursivity is broken. It seems that the .NET code uses the stack in a different way than my C code. I'm very unfamillar with the Windows world and the company that gives me the .NET application does not understand yet why there is such a failure. Any pointer/hint/advice welcome! Thanks!

  • ASP.net Error in Design Mode

    - by stringo0
    I just switched to VS 2010, and upgraded a previous project. I'm getting the following error on a page in design mode for 2 controls: Error Creating Control - ObjectName Object reference not set to an instance of an object. One of them is a simple label, and the other is a ajax update panel. Other pages look fine. When I build and test the app, the page renders fine in the browser and functions fine - the label functions as expected and the content in the update panel works as expected. Any ideas why I'm getting this error? I tried some of the google results to no avail. It'd be great to get this out of the way. Thanks!
