Taskmanager .NET

This is one of my bigger projects, so it will get its own site.

Now I restarted the development of my Taskmanager in C# and as I mentioned in my Daily Notes, it was very easy to design the UI. At least this is one big advantage of .NET. Due to evaluating the system near functions for enumerating processes, services, memory status etc. I had to realise, that they are not or only partial available via .NET. Enumerating service is available in .NET, but not completly. You get all services, their names, description and status, but you will not get the startup type...
Puh, not good so far. So I switched to WMI (WQI in my case). Thise is a .NET independent construct for getting system specific information, but can be very beautiful integrated to your C# project. Look at this:

    using System.Management;

    namespace Taskmanager{
      class ProcessIter{
        private ManagementObjectCollection GetServices(){
      ManagementObjectSearcher query = new ManagementObjectSearcher
        ("SELECT * FROM Win32_Service ");
      ManagementObjectCollection collection = query.Get();
      return collection;
    }

    public bool EnumServices(ref MyService []allservices){
      ManagementObjectCollection services = GetServices();

      foreach(ManagementObject service in services){
        // Do something unimportant
        string serviceState = service["State"].ToString();
        string serviceType = service["ServiceType"].ToString();
        string startmode = service["StartMode"].ToString();
        // Again do something
      }
      return true;
    }
      }
    }
    

As you can see, it is very easy. A reference for all WMI classes can be found on msdn.

02.01.2006: Today I wanted to add Windows shut down functionality, but found out that the ExitWindowsEx function seems not to be implemented in .NET in version 2.0. Another function I have to import. Do not like it, because now more than the half of all system near functions are dll imports and not native .NET. Well, enough from the incrash, now the download of the executable.
