  • Going Functional : Symbol Graph Implementation in F#

    In the previous post, we have seen the implementation of undirected graph data structure in F#. In this post, we will make use of the Graph data structure to implement the Symbol Graph data structure. You can read more about Symbol Graph data structure here.

  • Check If the Screen Saver Is Running Or Not?

    Although its rare but at times while building desktop based applications, we might come across situation wherein we are asked to handle “Screen Saver” operation i.e. perform some logic based on whether the “Screen Saver” is on of off.

  • Asynchronous Web Api Action Methods

    In one of my recent WPF project, we made extensive use of async-await pattern. Async-await pattern greatly simplified the call-back and continuation based code required for keeping the UI responsive. In WPF, the pattern for implementing async-await is to invoke the IO/CPU intensive code in a background thread and attach the continuation logic on the main UI thread. In WPF, since we have a dedicated UI thread that controls all of the UI elements, using async-await is really helpful in keeping the UI responsive without having to write complicated call-back based code.

  • WPF MVVMLight Toolkit & Capturing Control Events

    If you have worked with MVVMLight toolkit framework, then you must be familiar with the RelayCommand pattern for processing control commands. For example, if you have to handle the button click event using MVVMLight framework i.e. to not have the code-behind button click event handler but instead call some method in your ModelView class, then you can do it easily using the RelayCommand pattern. Below is a sample example :
