Visual Studio Code Snippet for a Notify Property (INotifyPropertyChanged)

updated version can be found here:  https://aaron-hoffman.blogspot.com/2017/12/vs2017-visual-studio-2017-code-snippet-wpf-inotifypropertychanged.html In the ViewModel classes of projects following the M-V-VM pattern it is often necessary to raise a "PropertyChanged" event (to assist with INotifyPropertyChanged interface implementation) from within a property's setter.  This is a tedious task that will hopefully someday be solved by using the Compiler as a Service...  But until that day comes, I've created a handy Visual Studio Code Snippet for myself to help automate this task.  The XML for the code snippet, and an example of the code it produces are below (note the Base Class and the OnPropertyChanged() method call).  Continue reading to see how to "install" and implement this snippet. -------- <? xml version = " 1.0 " encoding = " utf-8 " ?> < CodeSnippets xmlns = " http://schemas.microsoft.com/VisualSt

Silverlight Color Picker ComboBox (DropDownList)

During a Silverlight project I finished up a while ago I needed to create a "simple" Color Picker ComboBox (or DropDownList for us ASP.NET Developers).  By "simple" I mean limited to only a handful of colors, not as complex as something like Paint.NET (read PhotoShop) would provide.  This is the easiest solution that I found. The first thing you need to know is that the ComboBox has an ItemTemplate .  This template allows you to completely control the look and feel of each entry in the ComboBox.  From simple things like binding to a property to change the background color (hint hint, that is what we are about to do), to more complex things like changing the entire template based on the type of class being bound to this item in the ComboBox (ex: the ComboBox is bound to a list of "fruits" some are apples and some are bananas.  The apples all use one template, the bananas use a completely different template - powerful). We'll be binding this ComboBox

Simple Keystroke Automation in .NET (Scott Hanselman's Http Button)

-- Scott Hanselman ( http://www.hanselman.com/ ,  http://twitter.com/shanselman ) recently tweet'd, " I need a keyboard with an "http://www." button. " To which I replied, " @shanselman you still type the "http" part? I didn't think you had to anymore... "  Oooh, hahahaha, how smart and funny am I!?  ....Apparently not very... :-) shanselman responded (as well as to others with the same smart remarks), " @aaron_hoffman in tweetdeck or Twitter, you do. "  --Aaaah, I get it now, he's not in a browser! okay, he has me in Check . Now I just had to solve this problem.  Well automation/degree in laziness (with years of laziness experience) to the rescue!  At first I thought PowerShell  - but since I am on a WinXP SP2 machine, that wouldn't do.  I'll have to fall back to the console app & desktop shortcut combination of yester-system.
