I took the new logo for StatLight and created a/an .ico (by going to convertico.com) for use as a FavIcon and so I could fancy up a couple of the windows just for fun. What I ended up figuring out, was how to change the icon for a running console window.

It’s actually pretty easy… Here is the class I wrote and use.

internal class ConsoleIconSwapper : IDisposable
{
    IntPtr consoleWindowHwnd;

    private const int WM_SETICON = 0x80;	// Api constant
    private const int ICON_SMALL = 0;	// Api constant

    [DllImport("user32.dll")]
    private static extern int SendMessage(IntPtr hwnd, int message, int wParam, IntPtr lParam);

    [DllImport("kernel32")]
    private static extern IntPtr GetConsoleWindow();

    public ConsoleIconSwapper()
    {
        consoleWindowHwnd = GetConsoleWindow();
    }

    public void ShowConsoleIcon(Icon icon)
    {
        SendMessage(consoleWindowHwnd, WM_SETICON, ICON_SMALL, icon.Handle);
    }

    public void ChangeIconback()
    {
        SendMessage(consoleWindowHwnd, WM_SETICON, ICON_SMALL, (IntPtr)0);
    }

    public void Dispose()
    {
        ChangeIconback();
    }
}

And here is how I use it.

using (var consoleIconSwapper = new ConsoleIconSwapper())
{
    consoleIconSwapper.ShowConsoleIcon(CoreResources.FavIcon);
    /*
     *  Code Here
     */
}

This is what it looks like when in use…
