On request of a reader, I’ll show you today some C# basics. After I had posted a little snippet for dealing with the AppSettings, I was asked how we could now actually save user input on a GUI with help of this snippet. Here comes the solution.
For clarification, I have a created a little C# WinForms project in Visual Studio. The WinForm got a label and a textbox on it. Also the above mentioned functions for loading and storing values in the AppSettings will be used.

How to save settings really quick and easy in C # applications? I’m sure this question has been asked certainly by everyone once during his career as C# programmer. And did you know? The answer is quite simple. The easiest way to answer this question is to use the AppSettings from ConfigurationManager class of the .Net-Framework.
The. Net Framework brings its own managers to save and load settings with it. The properties are stored in the common XML format. And so you can see that dealing with the AppSettings is really a no-brainer , I have written two small functions for saving, changing and reading preferences.

//Load the appsettings
Configuration config = ConfigurationManager.OpenExeConfiguration(
System.Reflection.Assembly.GetExecutingAssembly().Location);

Original Gameboy It’s not often that I play games. And if I do, then my favorites are classic games. And yes, I still grow up with a Gameboy. With a large Gameboy. Since these are no longer available, I have already had one or two emulators in my hands. But what I’ve found now on the web, I’ve never seen before.
A student named Grant has developed his own Game Boy emulator. The remarkable thing is that it is completely written JavaScript and therefore runs online.

Since I needed a javascript based progress bar for a Web project and I could not find a component that meets my expectations, I decided to write my own progressbar.
The project was implemented in JavaScript with help of the HTML5 canvas element. The progress bar gets along without any image files, as it is usually the case with other JS / CSS progress bar solutions. By default it can handle 100 states (0-100%) and input errors will be caught and visualized.
Since I like to share my developments I present you the progressbar of course. I’m always open for criticism, praise and suggestions.

Below I will show you quickly how to use the progressbar.
At first you have to embed the progress bar […]
