• Dispatching generic tasks in WCF or .Net Remoting

  - by Eric

  Hello all, I've been researching for a couple days on and off, and have yet to figure out the best way to achieve the following goal. I would like to define either an interface or abstract class in C# which has an associated Run method, similar to the Java runnable interface. The goal would be to have a shared queue which contains a list of these objects. Then individual clients would be able to derive their own concrete runnable classes and add them to the queue hosted by the server. Clients would also be able to pop these runnable objects off the queue and execute them arbitrarily. This seems like it should be feasible in a VM based language without needing to place any of the concrete implementations in a shared assembly, but I have thus far had no luck finding a working example of such a system. Does anyone know how this might be achieved?

• Selecting radiobuttons populated within asp.net RadioButtonList with jQuery

  - by user194881

  Hello and thanks in advance for the communal help I always find here. I have been tinkering around with what should seem a pretty straight forward task even for a jQuery newb as myself. I have a radiobuttonlist control bound to a collection: <asp:RadioButtonList ID="radBtnLstPackageSelector" runat="server" CssClass="PackageS"> </asp:RadioButtonList> My form does have several other controls of the same type; Now, the challenge is to select and wire up a on Click event for every radiobutton from the radBtnLstPackageSelector. I have tried several approaches such as: var results1 = $(".PackageS").children("input"); var results1 = $(".PackageS").children("input[type=radiobutton"); var results1 = $("table.PackageS > input[type=radiobutton"); with no luck... Your help would be great right now! ~m

• ASP.net PreInit() Vs Init()

  - by ASP.netBeginner

  From local forum i understood that PreInit can be used to handle the following PreInit() >Master pages can be called dynamically >Themes can be set dynamically >Programatically add controls to controls collection and i read Init() is for Init() In this event, we can read the controls properties (set at design time). We cannot read control values changed by the user because that changed value will get loaded after LoadPostData() event fires. Question I am not getting the point "We cannot read control values changed by the user".Where do users change the value of control?.Example would help me to understand the point.

• 2 basic but interesting questions about .NET

  - by b-gen-jack-o-neill

  Hi, when I first saw C#, I thought this must be some joke. I was starting with programming in C. But in C# you could just drag and drop objects, and just write event code to them. It was so simple. Now, I still like C the most, becouse I am very attracted to the basic low level operations, and C is just next level of assembler, with few basic routines, so I like it very much. Even more becouse I write little apps for microcontrollers. But yeasterday I wrote very simple control program for my microcontroller based LED cube in asm, and I needed some way to simply create animation sequences to the Cube. So, I remembered C#. I have practically NO C# skills, but still I created simple program to make animation sequences in about hour with GUI, just with help of google and help of the embeded function descriptions in C#. So, to get to the point, is there some other reason then top speed, to use any other language than C#? I mean, it is so effective. I know that Java is a bit of similiar, but I expect C# to be more Windows effective since its directly from Microsoft. The second question is, what is the advantage of compiling into CIL, and than run by CLR, than directly compile it into machine code? I know that portability is one, but since C# is mainly for Windows, wouldn´t it be more powerfull to just compile it directly? Thanks.

• What is a .NET application domain?

  - by Luke

  In particular, what are the implications of running code in two different application domains? How is data normally passed across the application domain boundary? Is it the same as passing data across the process boundary? I'm curious to know more about this abstraction and what it is useful for. EDIT: Good existing coverage of the AppDomain class in general at http://stackoverflow.com/questions/622516/i-dont-understand-appdomains
