• Keeping an application on top and in focus - always

  - by James Newton-King

  I am creating a kiosk application and I want to ensure it is always, no matter what, on top of other Windows applications and the Windows task bar. I am already blocking Windows keyboard commands (alt-tab, etc) but there are still situations that could cause an application to launch and steal the screen. Is it possible to hook into Windows from .NET and continually test whether the application has focus and is on top, and if not then give it focus and make it on top?

• SWT Global Menu bar items listener

  - by vigilant

  Is it possible to attach a listener to all MenuItems in a Menu bar after creating the entire menu bar? Otherwise I need to call addListener on each MenuItem individually, which is a pain with hundreds of menu items (don't ask why). With a listener attached to each MenuItem, I would then be able to demultiplex using the text string of the MenuItem.

• Combine hash values in C#

  - by Chris

  I'm creating a generic object collection class and need to implement a Hash function. I can obviously (and easily!) get the hash values for each object but was looking for the 'correct' way to combine them to avoid any issues. Does just adding, xoring or any basic operation harm the quality of the hash or am I going to have to do something like getting the objects as bytes, combining them and then hashing that? Cheers in advance

• Can extension methods be applied to interfaces?

  - by Greg

  Hi, Is it possible to apply an extension method to an interface? (C# question) That is for example to achieve the following: create an ITopology interface create an extension method for this interface (e.g. public static int CountNodes(this ITopology topologyIf) ) then when creating a class (e.g. MyGraph) which implements ITopology, then it would automatically have the Count Nodes extension. This way the classes implementing the interface would not have to have a set class name to align with what was defined in the extension method.

• How to add a reference to my Web Service Proxy from a Custom Class

  - by coffeeaddict

  I'm creating a custom class to abstract out some of the repeated SOAP header work. I want to reference a Web Service Reference I just created in my custom class so I can create an instance of it. How do I reference it? Notice I said I am trying to reference a Web Service "reference" (right click in VS and I added a "Web Service Reference" not a "Web Service"). So I'm trying to create an instance of that Proxy class that was created in MyCustomClass.cs

• ASP.NET - What happens when a HttpCookie expiration has been crossed

  - by user70192

  Hello, I am creating some cookies in my ASP.NET application. These cookies expire 10 minutes after they have been created. I follow the approach described on MSDN as shown here: http://msdn.microsoft.com/en-us/library/system.web.httpcookie.expires.aspx My question is, when a cookie "expires", what happens? Does the browser automatically delete the cookie? Is it our responsibility as developers to remove the cookies if they exist and have expired? Thank you,

• Generate 2D cross-section polygon from 3D mesh

  - by nornagon

  I'm writing a game which uses 3D models to draw a scene (top-down orthographic projection), but a 2D physics engine to calculate response to collisions, etc. I have a few 3D assets for which I'd like to be able to automatically generate a hitbox by 'slicing' the 3D mesh with the X-Y plane and creating a polygon from the resultant edges. Google is failing me on this one (and not much helpful material on SO either). Suggestions?

• Create a jQueryUI 1.8 Button menu

  Now that jQueryUI 1.8 is out, I was browsing through the updates and came across the new Button widget, and in particular one of the demos with the SplitButton with a dropdown. This demo seems to suggest that the Button widget could be used to create a dropdown menu here. As a matter of discussion, I was wondering what ways there are to go about creating a dropdown menu with this new Button widget. Cheers.

• Specifying schema for temporary tables

  - by Tom Hunter

  I'm used to seeing temporary tables created with just the hash/number symbol, like this: CREATE TABLE #Test ( [Id] INT ) However, I've recently come across stored procedure code that specifies the schema name when creating temporary tables, for example: CREATE TABLE [dbo].[#Test] ( [Id] INT ) Is there any reason why you would want to do this? If you're only specifying the user's default schema, does it make any difference? Does this refer to the [dbo] schema in the local database or the tempdb database?
