Async Event Methods and preventDefault() in JavaScript



When using async events, it's important to understand how events work when called asynchronously. Specifically if you need to interact with the event context for things like preventDefault(), cancelBubble() or returning values that determine completion state, you need to be careful as these may have no effect if called after an `await` call.

UpperCase Styling via CSS and text-transform



I learned something new today: there's a CSS `text-transform` style property that can be used to transform text automatically to upper, lower or capitalized case. No JavaScript contortions and it just works. In all my years doing Web dev I've not run into this property before, so I'm posting it here for others to find as well...

A Button Only Date Picker and JavaScript Date Control Binding



The native date picker in HTML is a bit of a pain to work with as it's overly simplistic in features and how you have to assign and retrieve values from it. It also isn't customizable so if you need to build custom behavior like a button date popup that doesn't show the input control, you're out of luck. In this post I discuss the challenges of the HTML date picker control, provide small component to make binding values easier, and provide an example on how to create a button only date picker both with plain JavaScript and as a small Vue component.

Basic Windows Machine Hardware information from WMI for Exception Logging from .NET



When writing out error information for a desktop application to a log whether local or to a telmetry engine, it's useful to get some idea of what hardware the app is running on. WPF applications in particular can have odd behaviors that are related to hardware acceleration, running inside of a VM or particular video drivers. In this short post I show how you can get very basic machine and GPU information that provides information on these basic system stats that can prove useful to trackdown rare hardware related issues.
