First here's my slide deck and samples: Slides Code The "CoffeeShop" sample is...
D/FW Connected Systems Presentation August 13th
I will be speaking the D/FW Connected Systems User Group on August 13th. The topic I will present will be on implementing Windows Communication Foundation services with Windows Workflow Foundation. Update: Thanks to all of you who attended. I hope you learned something. I'll post my samples as well as links to the various resources I mentioned this evening. I'll also provide deeper dives into various...
Calendars Everywhere
I'm going to be honest with you. Buzzwords turn me completely off. This generally serves me pretty well. I avoid the hype train and catch on after the furious excitement is over and the kinks are worked out. I have caught a little bit of this "cloud computing" bug that everyone is on about, though. It all started when my service provider's email went down for about the 300 millionth time. I decided...
ASP.NET Is A Leaky Abstraction
One of the things that attracted me to development with ASP.NET as a relatively inexperienced developer were the server controls. They made development a lot like Windows Forms development. Just drag a button control and a TextBox control on a page and double-click to wire up your code to the button. Don't worry about state. Don't worry about input errors - we have more controls...
'Tis the Season
It's that time of year again for me to mention my favorite charity, Child's Play . This organization was started by a couple of video gamers a few years back to provide games and toys to hospitals that have kids staying with them. These children are often times dealing with conditions that keep them in the hospital for long stretches and anything that entertains them is a Good Thing. Child's Play has...
Doubling Your Family in Just 7 Minutes
I hear nothing changes you like the birth of your first child. While I am sure this is true, I had just 7 minutes to reflect on this before the birth of my second child. My identical twin daughters, Andriana and Alexandra were born on October 8th at 12:45p and 12:52p. They were 5 lbs. 3 oz. and 5 lbs. 7 oz, respectively. It was difficult getting them here, but it was definitely worth the work. They...
Invalid Postback with Ajax Update Panels
I've been getting a strange error lately when enabling some complex functionality using update panels. The error looks like this: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback...
.NET Windows Service Runner
I've had a lot of people say that the Service Loader I created is great, but that they would like the ability to run the service without a debugger attached, like from the command line or similar method, but still not require the service be installed as a Windows Service. I created a new application as an enhancement to the original Service Loader called the Service Runner. What is beautiful about...
Machine is Disabled for File Encryption Installing Visual Studio 2008 on Windows Vista
There are a few programs that require Encrypting File System (EFS) to be turned on in Windows Vista. Among them: Various Hotfixes Windows Powershell .NET Framework 3.5 (and subsequently Visual Studio 2008) This occurs because there is a group policy set on your domain that prevents this from being enabled. It causes several variations of the following error message: Installer encountered an error:...
Finally a Reason I'll Install Vista for My Mom
I've been using Vista for a while now, both at work and at home. Up until now, I've mostly felt that it's just a slight upgrade from Windows XP. I understand all of the work that went into the underpinnings and such and from a developer perspective I can certainly appreciate these. From a regular user's perspective, I'm concerned with features and of the features that I've used, the system-wide search...
Limes ARE Lime Green
It's sometimes interesting to think about the decisions that went into the software that we use. There is an interesting article or two on the design decisions surrounding the Start menu in Windows Vista . These large design decisions are very interesting and have far-reaching impacts. It's fascinating to me to think about everything that is involved in deciding what word should describe something...
Null Child Object After Deserialization
I have been running into a situation a lot lately, especially with applications that utilize WCF services. Specifically, it deals with deserialization, so I wanted to write up a little bit about what I have found and some best practices. Problem Consider the following scenario. You have the following object, defined in your WCF service: [DataContract] public class Programmer { [DataMember] public List<...
Demand UAC Elevation for an Application
The UAC messages can get as annoying as the Apple advertisements suggest, but if you haven't considered UAC in an application that runs on Windows Vista, you might be in for a nasty deployment surprise. I recently had to write an application that did some swimming around in Active Directory, which obviously requires elevated credentials. I got tired of right-clicking the application and clicking "Run...
My Two Peanuts
It's been a while since I posted. Life's been catching up with me lately, but I'm determined to wrestle it to the ground. That was the requisite "it's been so long" comment. Moving on. I've had a lot of really banner things happen lately. For one, I've been converted to a full-time employee of Mary Kay . I'm loving working there so I was happy they wanted to keep...
Kombucha
I've discovered over the years by watching shows like Good Eats and reading On Food and Cooking that creating food is a science. Some of it is chemistry, some of it is math, some of it is physics, but it's all science. I was nudged in the direction of creating food using biological science by reading various tidbits of Jay Bazuzi's blog . Jay has made cheese , kvass , and sauerkraut. All of these foods...
