IIS6 - which W3WP.EXE belongs to which application pool

Our servers run with a number of application pools to separate load between several intensive websites/processes. When everything is running fine management is easy but if an application pool begins to use excessive resource it is necessary to identify which W3WP.EXE process is using the resource and therefore which app pool is causing the problem.

Microsoft have provided a script file (.vbs) to list all W3WP.exe processess, the PID and the application pool. Simply open a command prompt (Start > Run, enter "cmd", click OK), type iisapp and hit return. Below is an example of the output:

W3WP.exe PID: 1468 AppPoolId: AppPoolForSite1.com
W3WP.exe PID: 3056 AppPoolId: AppPoolForSite2.com
W3WP.exe PID: 1316 AppPoolId: AppPoolForSite3.com

Thank you ASP Alliance for this one:

Take website screenshot using ASP.NET

Utilising a hidden web browser control it is possible to take a screenshot of any website. The code shown below is based on an article at plentyofcode.com (sorry the site now appears to be offline May 2012) but I have translated it from VB.NET to C# and will work in .NET so theoretically for any Windows or ASP.NET web project.
using System; using System.Drawing; using System.Drawing.Imaging; using System.Windows.Forms; using System.Diagnostics; namespace WebsiteScreenshot { public class GetImage { private int s_Height; private int s_Width; private int f_Height; private int f_Width; private string myURL; public int ScreenHeight { get { return s_Height; } set { s_Height = value; } } public int ScreenWidth { get { return s_Width; } set { s_Width = value; } } public int ImageWidth { get { return f_Width; } set { f_Width = value; } } public int ImageHeight { get { return f_Height; } set { f_Height = value; } } public string Website …

John Hamblin Furniture Restorer - New Website

I was asked to produce a new website for local furniture restorer and cabinet maker John Hamblin. Having struggled with another provider who failed to deliver a finished website I was asked to take the website on and produce a simple site that communicates their values of high quality workmanship and excellent customer service.

The new website is live and can be viewed here:

Compress and de-compress strings in C#

A collection of resources on compressing and encrypting strings in C#.
Microsoft documentation on the System.IO.Compression.GZipStream class:
http://msdn.microsoft.com/en-us/library/system.io.compression.gzipstream.aspx
Helpful example class utilising GZip:
http://www.csharphelp.com/2007/09/compress-and-decompress-strings-in-c/
The GZipStream class is predominantly used for file compression but can be used efficiently for compressing strings of 300-400 characters or more. Below 300 characters there isn’t any measurable gain from the compression and for particularly short strings the compressed version may in fact be larger.
Class provided by C Sharp Help:
using System.IO.Compression;
using System.Text;
using System.IO;
public static string Compress(string text)
{
    byte[] buffer = Encoding.UTF8.GetBytes(text);
    MemoryStream ms = new MemoryStream();
    using (GZipStream zip = new GZipStream(ms, CompressionMode.Compress, true))����…
