Hi Community, This post is about how to check whether the binary representation of a byte is a palindrome. I’ve recently received an email by a fellow developer requesting some help with this, and after having done a bit of research I couldn’t find any good example written in C#, so I decided to do […]
How to properly sign-out users when session times out on an MVC app using ADFS as authentication mechanism
Hi Community, Today’s post is about a common issue faced by many Web developers when they build an MVC Web application that uses ADFS as its authentication mechanism. The problem lies that sessions might be abandoned by IIS when their time is up, but the MVC application might not even be aware of this fact, […]

Whatis Utility for Windows
Hi Community, I’ve just come back to the office after rolling off from an engagement, so this week while being back to the bench I’ve been practicing and studying some Qt for my upcoming certification, doing a few things around Raspberry Pi + Kinect + OpenKinect on Raspbian but at the same time I also […]
Windows 10 and Visual Studio 2015 Resources

Instrumenting SharePoint code via Performance Counters
Instrumentation is an important and integral part of every system because it allows (among some other things) to monitor the health of the system and/or components of it. On a recent engagement, I had to architect a SharePoint solution that integrates with a core LOB system. The SharePoint solution comprises a few workflows that in […]
Communication between user and kernel-mode
As a follow-up post on Windows Services and Minifilters, Today I’ll explain one way we can send notifications from kernel-mode to an user-mode application. Let’s remember Windows provides fault tolerance protection in the form of rings, thus an offending code in one of the rings should not compromise the stability of the system. My metadata […]
Dynamically add event handlers to controls in a custom .NET control with C#
A few years back I came up with something called “FRF” (Forms Rendering Framework) which allowed me to render any UI (whether they are Web or Windows based) based on a template definition (Yes, this was long before Microsoft released XAML). Anyways, on one of my personal projects I had a requirement to dynamically create […]
Pass information to .NET control from Native Code with Visual C++

First of all, we need to define an interface with […]
Unit testing our Visual C++ code with Microsoft Unit Testing Framework
One of the things I love about unit testing (besides all of the well-known benefits) is the ability to test code without writing a tester or test harness application, but I can pretty much leverage what Microsoft have already built for us. Image below depicts an unit test I’ve written for this JNI .NET bridge or […]
