WPF – Override Decimal Separator for the current CultureInfo
Lets say we want to keep the current en-US culture format but override the way the Decimal is represented (normaly with a dot (.) but here we want a coma instead (,). System.Threading.Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(“en-US”); var currentCulture = System.Threading.Thread.CurrentThread.CurrentCulture.Name; var ci = new CultureInfo(currentCulture) { NumberFormat = { NumberDecimalSeparator = “,” } }; System.Threading.Thread.CurrentThread.CurrentCulture = ci; […]

C# – Set the Wallpaper by code
There is no simple way to set the wallpaper. We have to use a Windows DLL to do that. And this DLL is able to set the wallpaper only if the image is a BMP. So we have to convert it first. using Microsoft.Win32; using System.Drawing; using System.Drawing.Imaging; using System.IO; using System.Runtime.InteropServices; namespace WindowsStarter { […]
