custom-attributes

Working on writing a custom property Handler for our custom file type in windows 7. I have installed the Windows 7 SDK and built the sample Property Handler. After registering the handler, it works great in Windows Explorer, but in the common file open dialog the custom values do not appear. Does anyone know if there is something special I need to do to get the properties to appear in common dialogs? Explorer: File Open Dialog: OK, figured it out. Here is the deal. My app is 32 bit and I am on a x64 system. Because the PropertyHandler is written in x64 to support the shell out of process. But

I'm working an a ASP.NET application (not using MVC) and need a User-Role-Permission based authorization scheeme, where pages and/or methods can demand the specific permission they require (instead of which role the user has). Is there a way to extend Forms Authentication (or building something) to solve this? If possible I would like to be able to use attributes: [RequirePermission("UserEdit")] public partial class EditUser : System.Web.UI.Page { } Perhaps even for methods: public class MyClass { ... [RequirePermission("UserEdit")] public void Save() { ... } } Is this possible? I found this

I've created a custom attribute which writes to the console when it's hit, however it doesn't seem to be hit. It's the microsoft tutorial (http://msdn.microsoft.com/en-us/library/sw480ze8.aspx) and is being run on 2010, .net 4. I'm guessing it must be me that's doing something wrong, but I can't see what it is. Can anyone help? This is the attribute, whose code is never being hit [AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct)] public class Author : Attribute { private string _name; private double _version; public Author(string name) { Console.WriteLine(string.Format("author

It seems Aurelia is not aware when I create and append an element in javascript and set a custom attribute (unless I am doing something wrong). For example, const e = document.createElement('div'); e.setAttribute('custom-attr', 'some value'); body.appendChild(e); Is there a way to make Aurelia aware of this custom attribute when it gets appended? A little background: I am creating an app where the user can select their element type (e.g. input, select, checkbox etc.) and drag it around (the dragging is done in the custom attribute). I thought about creating a wrapper <div custom-attr repeat

Greetings StackOverflow, If I've got an enum type with the Flag attribute as well as the values in this enum type with their own attributes, how can I retrieve all of the appropriate attributes? For example: [Flags()] enum MyEnum { [EnumDisplayName("Enum Value 1")] EnumValue1 = 1, [EnumDisplayName("Enum Value 2")] EnumValue2 = 2, [EnumDisplayName("Enum Value 3")] EnumValue3 = 4, } void Foo() { var enumVar = MyEnum.EnumValue2 | MyEnum.EnumValue3; // get a collection of EnumDisplayName attribute objects from enumVar ... } A quick and dirty way using Linq: IEnumerable<EnumDisplayNameAttribute>

I have a custom attribute which can be assigned to a class, [FooAttribute] . What I would like to do, from within the attribute, is determine which type has actually used me. e.g. If I have: [FooAttribute] public class Bar { } In the code for FooAttribute, how can I determine it was Bar class that added me? I'm not specifically looking for the Bar type, I just want to set a friendly name using reflection. e.g. [FooAttribute(Name="MyFriendlyNameForThisClass")] public class Bar { } public class FooAttribute() { public FooAttribute() { // How do I get the target types name? (as a default) } }
