A day in the life of...

The technologies I used in an app I wrote for friends recently. The app manages properties at different locations, bookings, and tariffs. In addition to this the application (which uses SQLite) connects to their website using WCF and updates their database so that people can check prices and availability. I need to get them using it now so that there is data available by the time I put up their website .

In a previous post I showed how to return a binary file from a controller action, well, this no longer works in release candidate 3 of the framework. Instead you have to create a new ActionResult descendant to do the job for you. This is how I did it.... return new BinaryResult(data, Path.GetFileName(productFileName)); and the class is implemented like so: public class BinaryResult : ActionResult { private string ClientFileName; private byte[] Data; private string VirtualFileName; public BinaryResult(string virtualFileName, string clientFileName) { if (string.IsNullOrEmpty(virtualFileName)) throw new ArgumentNullException("VirtualFileName"); if (string.IsNullOrEmpty(clientFileName)) throw new ArgumentNullException("ClientFileName"); ClientFileName = clientFileName; VirtualFileName = virtualFileName; } public BinaryResult(byte[] data, string clientFileName) { if (data == null) throw new ArgumentNullException(...

I'm trying to upgrade from Preview 2 to Preview 3. I think the idea of having each action return an ActionResult was a good one, so far it has actually made my code slightly smaller. What I don't understand though is why Html.Select seems to have disappeared... Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. Compiler Error Message: CS1501: No overload for method 'Select' takes '5' arguments Source Error: Line 8: Product Line 9: Line 10: Line 11: Line 12: When I go into the APX and type Html. there is no Select method listed along with the other options! Where is it?

Today I wanted to give access to certain files on a website only via my DownloadController. This was so that I could ensure the current user had purchased the item in question first, and also sign any license info into the download aswell. I tried getting a URL like this to work http://localhost/download/1/SomeFileName which would remap to the DownloadController public void Index(int id, string fileName) This worked fine, and because the URL ended with "SomeFileName" it would get saved as the correct filename too, but this was no use because SomeFileName has no file extension. As soon as I added .zip on the end the request no longer went via the new HttpHandler in the MVC web extensions. Even when I added it in the <httpHandlers> section of web.config it just wouldn’t work. My problem was in relying on the url for the filename. This is apprarently not the way it should be done. Instead I should have stuck to the standard URL approach http://localhost/download/1 an...

I have decided that mocking IEcoServiceProvider is not the way to go. Your controller will use the mocked provider during testing but   You don’t want to have to mock every service the provider may return, it’s a lot of work!   You don’t want your controller using a mocked service, and then the EcoSpace using the real one! At first I was mocking every possible service request. IUndoService, IPersistenceService, IOclService, etc. I get bored typing them out in this blog, so doing it in tests was really annoying me. I decided I would instead only mock the service in question. So if I were ensuring that an action wont save an object with broken constraints I would mock GetEcoService<IConstraintProvider> and ensure that I always got a broken constraint. The problem was that the test to ensure I can save a valid object would then invoke the IPersistenceService.UpdateDatabaseWithList method. In my EcoSpace I have decorated my persistence service so th...

I’ve been finding LINQ + Anonymous types really compliment ECO and the new ASP web extensions approach to writing websites. I may have mentioned recently that I don’t like the idea of passing instances of my business objects to the presentation layer. The reason is that someone else will be writing the views for this site and I want to be able to control what they are capable of displaying. It’s not just that though, the fact is that your view might need to look completely different to how your business classes are structured, one layer should not dictate the structure of another. The example I am about to show does in fact have similar structures for the view and model. Having said that there is a slight difference in that the MinorVersion class has its own "int VersionNumber" property, and gets the major part of the version number from self.MajorVersion.VersionNumber. Anyway, now to get on with it. My requirement was to show all major versions, within each major...
