Hi All,

Is there any sample code on how to get the total PC CPU usage by using
WMI, it will look like the task manager one.

I have tried to use the performanceCounter, but it has permission
problem in the Vista with UAC enabled.

And i have tried to find in the Internet, but seems no complete code
for getting the total PC CPU usage, Thanks

Something like:

using System;
using System.Management;

public class MainClass
{
public static void Main(string[] args)
{
ObjectQuery wmicpus = new WqlObjectQuery("SELECT * FROM
Win32_Processor");
ManagementObjectSearcher cpus = new
ManagementObjectSearcher(wmicpus);
foreach (ManagementObject cpu in cpus.Get())
{
Console.WriteLine(cpu["DeviceId"] + " : " +
cpu["LoadPercentage"]);
}
}
}

?

I don't know. You will need a more Windows knowledgeable person
than me to answer that question.
