Mortgage comparison websites and free online mortgage calculators are good tools to use when deciding what mortgage to choose. But in my opinion they aren’t good enough! A few years ago when my partner and I were buying our first house in the UK, I was perusing the mortgage options … Continue reading
In my previous post, I created a small Windows Presentation Foundation (WPF) application demonstrating Storyboard Animations where I also described how and why to Model-View-ViewModel (MVVM) pattern to the code. Recapping, the benefits of adopting the MVVM pattern include providing a separation of concerns between the application logic and the presentation logic and … Continue reading
In part one I described how to control Storyboard animations using triggers. I created a demo application to provide an example use case. In this post I will discuss converting the demo application to adopt the Model-View-ViewModel (MVVM) pattern as well as describing why this is a worthwhile exercise. MVVM What is MVVM? It … Continue reading
In my previous post I described how DataTrigger and MultiDataTrigger can be used to customise the style of a UserControl . Now I want to expand on the usage of these triggers, specifically to control Storyboard animations. In this post I will describe how to achieve this using dependency properties (DP) and logic … Continue reading
Recently I was doing some WPF work and was trying to customize the display of a UserControl based on a dependency property (DP) of that same UserControl . This post will outline what I learnt about DataTriggers and MultiDataTriggers while completing the task. The first goal was to adjust the vertical alignment … Continue reading
PPL Task While playing with the concurrency features in C++11, I noticed that there wasn’t any support for continuations. As a learning exercise I decided to develop something similar to tasks in The Parallel Patterns Library (PPL), where a task can run asynchronously and execute a continuation upon completion using the then member … Continue reading
Previously we saw how to convert a float to a binary value as well as how to extract the relevant integer and fractional parts from that binary value. We also saw the rules and logic for carrying out addition and subtraction. Now we will look at multiplication and division of these binary … Continue reading
Have you ever wondered how floating point operations are actually represented on a computer? No? Me neither 🙂 However I have been reading a book called ‘Mathematics and Physics for Programmers’ by Danny Kodicek and the first chapter covers this. For one of the exercises it recommends writing code to … Continue reading
I have come across a few good examples of the Producer-Consumer pattern, however they tend to use contrived examples that don’t correlate well to a real world example. I realise that the examples are generally contrived for the sake of brevity and in order to keep them clear and concise. I admit that the … Continue reading
I recently worked on a tool to wrap the creation of Autodesk Maya Constraints. I wanted to be able to validate the functionality of the tool without testing the GUI. Visual Studio (currently VS2013) is my IDE of choice and I really like the Test Explorer that is provided in VS … Continue reading
