hey guys. Firstly I can't get my head around the functional / Lambda aspects of .NET 3.5. I use these features everyday in LINQ, but my problem is understanding the implementation, and what they really mean (Lambda? System.Func? etc etc) With this in mind, how would the following be achieved: As an example, I'd like to have an Extensi...
How can I customize the sorting of categories in a PropertyGrid? If I set either of the following... propertyGrid.PropertySort = PropertySort.Categorized; propertyGrid.PropertySort = PropertySort.CategorizedAlphabetical; ... then the categories will be alphabetized. ("Alphabetical" would seem to apply to the properties within each ca...
This is more of a philosophical question, perhaps. Let's say I have a framework of some sort and I decide to provide a .NET library that makes the use of certain aspects of the framework easier. I don't want each application that uses the framework to carry a copy of the library locally, so I want it in the GAC (even with all the mainte...

Hi I have recently started off with LINQ and its amazing. I was wondering if LINQ would allow me to apply a function - any function - to all the elements of a collection, without using foreach. Something like python lambda functions. For example if I have a int list, Can I add a constant to every element using LINQ If i have a DB tabl...

Could anyone explain me why the generics list's Contains() function is so slow? I have a List with about a million numbers, and the code that is constantly checking if there's a specific number within these numbers.

Hi, I'm trying to create a fairly extensive UserControl incorporating square controls into the design, and allowing resizing. Because the design calls for squares, I need all the columns in my TableLayoutPanels to be the same width, so that the contained, docked controls are also square. Unfortunately, the behaviour of the TableLayoutPa...
I have an WCF REST service which returns objects serialized with XmlSerializer. How can I add XSL stylesheet information (like the one below) to the output returned by the WCF service? <?xml version="1.0" encoding="utf-8"?> <?xml-stylesheet type="text/xsl" href="transforms/Customer.xsl"?> <Customer> <Name>Foo</Name> </Customer> My...

I'm working on some application, that uses a TreeView control to represent business objects. Currently the link between business objects and TreeNodes is maintained through the Tag property of the TreeNode. Im not very happy with this, because I think the link is not "tight" enough. For example there could be an TreeNode object without a...

I've mapped .mvc to aspnet_isapi.dll in IIS but get a 404 when I browse to my mapped URL which looks like this RouteTable.Routes.MapRoute("action", "api.mvc/{controller}/{action}", new {action = "Index"}); I then browse to //localhost...

What is the best way to create a JSON web service? We have another team that is using Java and they insist to having all communication done using JSON. I would prefer to use WCF rather than any 3rd party framework. I found this blog: http://www.west-wind.com/weblog/posts/164419.aspx, and it suggests that the Microsoft implementation is ...
I'm sure this was asked somewhere in another question, but the wording used there obviously is not generic enough to find easily. How do I tell my windows forms application about secondary locations that it can find assemblies that it may need at run time? I'm not talking about using reflection to discover plugins, but rather dependenci...
