Let's do some basic troubleshooting
- Remove the filter criteria and see if it runs. If it does then the problem is the filter
- Put back the filter but before you loop through the collection, check the number of items in the collection. there should be a Count or Length property that you can check
@Simon, while Rad has suggested the above, pls also run the general C Sharp script below. The script below runs well on my machine. HTHs to root cause, especially with the messagebox display error.
using System;
using System.Management;
using System.Windows.Forms;
namespace WMISample
{
public class MyWMIQuery
{
public static void Main()
{
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher("root\\CIMV2",
"SELECT * FROM Win32_ClassicCOMClassSetting");
foreach (ManagementObject queryObj in searcher.Get())
{
Console.WriteLine("-----------------------------------");
Console.WriteLine("Win32_ClassicCOMClassSetting instance");
Console.WriteLine("-----------------------------------");
Console.WriteLine("Caption: {0}", queryObj["Caption"]);
}
}
catch (ManagementException e)
{
MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
}
}
}
}
