Back from Hibernation :-)

It is almost 3 months i blogged, got myself tied up for happier personal reasons. To re-start with c# (.net 1.x) code to scrap daily dilbert comic and set it as desktop wallpaper.

Due to frequent demand for this, download the application here. Copy GetDilbert.exe to a folder and create a shortcut in windows startup.

using System;
using System.Drawing;
using System.Text;

using System.Runtime.InteropServices;
