Error registering WCF host in Windows Vista (HTTP could not register URL http://+:80)

This is an error encountered by one of my team when trying to run up a WCF host on a Windows Vista machine.  The actual exception is an

AddressAccessDeniedException

with the error message

HTTP could not register URL http://+:80/. Your process does not have access rights to this namespace (see http://go.microsoft.com/fwlink/?LinkId=70353 for details)

The Microsoft site (http://go.microsoft.com/fwlink/?LinkId=70353) does have a solution to the problem using httpcfg and netsh. However the far simpler solution is to run Visual Studio as Administrator

You can do that by right-clicking the shortcut for Visual Studio and selecting Run as adminstrator, or to permanently run as Administrator, right-click and select Properties. Find the Compatibility tab and check the Run this program as administrator checkbo€x.

C# Image from a byte array (and back again)

Quick code sample for transforming a .NET System.Drawing.Image into a byte array:

public byte[] imageToByteArray(Image imageIn)
{
    MemoryStream ms = new MemoryStream();
    imageIn.Save(ms,System.Drawing.Imaging.ImageFormat.Gif);
    return ms.ToArray();
}
and conversely, turning a byte array into an image:

public Image byteArrayToImage(byte[] byteArrayIn)
{
    MemoryStream ms = new MemoryStream(byteArrayIn);
    Image returnImage = Image.FromStream(ms);
    return returnImage;
}
