Windows Installer Cleanup Utility

Freeing up space on your hard disks is an ever ongoing battle for some people, for instance if you at some point decided on a too small system partition (“10 Gigs must surely be enough?”).

So in the Windows directory (on Windows XP at least) there is a folder called “Installer” where many install files will be found. It may be tempting to just delete all files here, freeing up many gigs of space, but that could cause problems later, for instance if you want to upgrade some program that needs the old version to be uninstalled first.

So this is where the Windows Installer Cleanup Utility comes into play. Read this excellent blog post on where to get it and how to use it: http://blogs.msdn.com/heaths/archive/2007/01/31/how-to-safely-delete-orphaned-patches.aspx

Essentially after installing the utility, you may run a command that will delete orphaned installation files, that is install files for programs that are no longer on your system.

I managed to free up enough space to install MS VS 2008 Professional… :)

SendHttpRequest

I made a little console application using .NET 1.1, that sends a request to an address given as parameter. It is to be used to simulate traffic on a web site. Probably could use some refinement of the code (just consider it my alpha, and that there will be no beta, RTM, etc.).

using System;
using System.Web;
using System.IO;
using System.Net;

namespace SendHttpRequest
{
    /// <summary>
    /// Summary description for Class1.
    /// </summary>
    class EntryPoint
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main(string[] args)
        {
            if(args.Length > 0)
            {
                string url = args[0];

                Uri uri = null;
                try
                {
                    uri = new Uri(url);
                }
                catch
                {
                    Console.WriteLine("Invalid URL. No request sent.");
                    return;
                }

                WebRequest request = WebRequest.Create(uri);
                request.Method = "GET";

                WebResponse response = null;
                try
                {
                    response = request.GetResponse();
                    StreamReader rdr = new StreamReader(response.GetResponseStream());
                    string content = rdr.ReadToEnd();
                    Console.WriteLine(content);
                }
                catch (Exception ex)
                {   
                    Console.WriteLine(ex.Message);
                    return;
                }
            }
            else
            {
                Console.WriteLine("Usage: SendHttpRequest {url}");
            }
        }
    }
}
