Hi everyone! I'm new to data binding and encountered the following oddity today which I fail to understand: I have a form with two labels (labelA and labelB) and two buttons (buttonA and buttonB). The form hosts an object (called "formState") with two properties (CountA and CountB). labelA.Text is data-bound to formState.CountA, labelB...
I'm trying to serialize data that's about 30KB and I need to find a faster way to serialize/deserialze the data. For me speed is as important as size so either I find a way to compact the data more tightly or I need to have a faster mechanism to build the objects. I've tried building some custom methods for it as well as using the buil...
Our current app stores all dates via the server's datetime. I'm thinking we need to update all datetime values in the database over to UTC time. Now for displaying these dates back to the user, I know .Net 3.5 has datatypes that are specific to date time offsets. But does anyone see anything wrong with setting an application variable...

I'm the only developer in my company, and am getting along well as an autodidact, but I know I'm missing out on the education one gets from working with and having code reviewed by more senior devs. Does anyone know of any sites/resources that provide volunteer mentors? I'm looking for some one to review my code from time to time and g...
As a learning experience I recently tried implementing Quicksort with 3 way partitioning in C#. Apart from needing to add an extra range check on the left/right variables before the recursive call, it appears to work quite well. I knew beforehand that the framework provides a built-in Quicksort implementation in List<>.Sort (via Array....
This seems like a really basic thing that I'm doing, yet I'm tearing my hair out trying to make it work. My situation is this: I have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup.

Hi, I was reading up on ActiveMQ which seems like a great implementation of a servicebus where producers can post messages and other processes can receive them. However when reading the documentation, it looks like the producer has to give the 'endpoint' when sending a message. I would rather have it the other way around: My producer ...
I have a large list of values (100-200 character strings) and I need to return a distinct listing of them. What is the most efficient way to do this using .NET?
