In this guide, I’ll walk you through the process of implementing a folder selection UI using C#.

In many applications, users need to specify a folder where certain files will be saved or retrieved. Providing a user-friendly way to select folders enhances the overall usability of your application.

To implement a folder selection dialog in C#, we’ll use the FolderBrowserDialog class provided by the .NET framework. This class allows users to browse and select folders from their file system with ease.

Hi there, this is a new tutorial category in my blog. It’s Computer Vision. In this blog, I’d like to show you something cool. It’s how to perform Face Detection using your camera or Webcam. You’ll see how your application can detect faces from a captured image. Curious about it? Let’s take a look how to do that.

This what you need to follow this tutorial:

Microsoft Visual Studio 2010. Or if you don’t have one, you can use 2008 version.
Emgu CV (OpenCV in .NET). You can download the latest version in this link: www.emgu.com/wiki/index.php/Main_Page and follow the installation instruction.
Basic Knowledge of C# Programming.
Familiar in WPF Development.

After you’ve got what you need, it’s time to rock!

This is my first time I made a tutorial about WPF. I don’t think it’s a new technique, but I just want to share what I learned at home. I assume that you understand WPF a little bit. In this tutorial I’d like to show you how to load external image into WPF using OpenFileDialog.

Step 1

Create a new WPF Project, File → New → Project… and chose WPF Application (by the way, I’m using Visual Studio 2008 in this tutorial). You’ll see an empty window called Window1.xaml.

Password Encryption using MD5 Hash Algorithm in C#

Update (Sep 14, 2018): The new complete string hash algorithms in C# tutorial is available. I would suggest not to use MD5 anymore, because it’s not safe and easily collide. But I’ll leave the original tutorial here for educational purpose.

It’s really bad if someone knew your password. As a software developer, we have an ethic that we also don’t want to see other’s password. Which mean, storing password in a plain text is a nope.
