Feature suggestion.

It would be useful to include information on a web host's trust level 
(typically I'd used to this confirm that I'm on medium trust/shared-
hosting).

Example code snippet:

AspNetHostingPermissionLevel GetCurrentTrustLevel()
{
    foreach (AspNetHostingPermissionLevel trustLevel in
            new AspNetHostingPermissionLevel[] {
            AspNetHostingPermissionLevel.Unrestricted,
            AspNetHostingPermissionLevel.High,
            AspNetHostingPermissionLevel.Medium,
            AspNetHostingPermissionLevel.Low,
            AspNetHostingPermissionLevel.Minimal 
        })
    {
        try
        {
            new AspNetHostingPermission(trustLevel).Demand();
        }
        catch (System.Security.SecurityException)
        {
            continue;
        }

        return trustLevel;
    }

    return AspNetHostingPermissionLevel.None;
}

Great script, one fix for you:

Memory information on a 64bit system is incorrect.

Redefine MemoryInfo as:

        [StructLayout(LayoutKind.Sequential)]
        public struct MemoryInfo
        {
            public uint dwLength;
            public uint dwMemoryLoad;
            public IntPtr dwTotalPhys;
            public IntPtr dwAvailPhys;
            public IntPtr dwTotalPageFile;
            public IntPtr dwAvailPageFile;
            public IntPtr dwTotalVirtual;
            public IntPtr dwAvailVirtual;
        }

And cast them to ulong's before formatting.

Thanks.

What steps will reproduce the problem?
1. Run/display the 'info.aspx' page.
2. Scroll down to the 'Processor Information' section.
3. Below 'Page Size', see the exception.


What is the expected output? What do you see instead?
The 'GetSystemProcessorInfo_WMI' method should display processor/management 
information, but throws/displays the following:

System.NullReferenceException: Object reference not set to an instance of an 
object. at 
ASP.umbraco_aspnetsysinfo_info_aspx.GetSystemProcessorInfo_WMI(DataTable table)


What version of the product are you using? On what operating system?
Using rev.23 on Windows 7, IIS 7.5, ASP.NET 3.5
