mfc, CPU Usage

1. CPU usage amd memory usage

I am using the following code to get the CPU usage

PerformanceCounter myCounter;
myCounter = new PerformanceCounter();
     
myCounter.CategoryName = "Processor";
myCounter.CounterName = "% Processor Time";
myCounter.InstanceName = "_Total";

for(int i=0; i < 20; i++)
      myCounter.NextValue();

I ran this progam i am seeing values 0 or 100%, but when i see the task 
manager the CPU usage is 6 to 22 %. 

Am i missing something

3. How to get CPU Usage using C# .Net

Hi
   I have an C# application in which I am using WMI to obtain CPU
Usage of the total system. I obtain the CPU Usage in % for System Idle
Process and subtract it from 100 to obtain CPU Usage.
Here is the code to obtain CPU Usage

            ManagementScope scope = new ManagementScope("root\
\CIMV2");
            scope.Options.Impersonation =
ImpersonationLevel.Impersonate;

            ManagementObject obj = new ManagementObject();

             string strIdle = "Idle";
            char b = (char)34; //Double Quotes

            string stPath =
"Win32_PerfFormattedData_PerfProc_Process.Name=" + b + strIdle + b;
            ManagementPath path = new ManagementPath(stPath);

            obj.Path = path;
            obj.Scope = scope;
            obj.Get();
 
Debug.Print(obj.Properties["PercentProcessorTime"].Value.ToString ());

I have given this in a while loop to print System Idle Time. But I am
getting 0 always. I searched in google to find something that will
help. I came through the following script.

function abc(x)
            strComputer = "."
            Set objWMIService = GetObject("winmgmts:" _
             & "{impersonationLevel=impersonate}!\\" _
             & strComputer & "\root\cimv2")

            Set PerfProcess = objWMIService.Get(_
               "Win32_PerfFormattedData_PerfProc_Process.Name='idle'")

            Dim i
            i = 0
            While ( i < 20)
            PerfProcess.Refresh_
            Wscript.Echo PerfProcess.PercentProcessorTime
            Wscript.Sleep 1000
            i = i+1
            Wend
end function

This script is giving me valid Values. I compared with Task Manager
CPU Usage. Now I tried calling this script from my C# code. I created
a ScriptControlClass instance and called the Run method after Adding
the script to the instance. See the code below


                MSScriptControl.ScriptControlClass ms;
	ms = new MSScriptControl.ScriptControlClass();
	ms.AllowUI = true;
	ms.Language = "VBScript";
                ms.UseSafeSubset = false;
                ms.Reset();

                string str = rftScript.Text;//This is obtained from my
Form. I am copying
                                                     //script to a
Text Box in my form
                object[] i = new object[1];
                i[0] = "1";
                ms.AddCode(str);
                object oRes = ms.Run("abc",ref i );

When I run this piece of code it will give me an Exception "Generic
Failure" where ms.Run is called. I commented out
"PerfProcess.Refresh_" in VBscript and then this piece of code works
without any exception. But the problem is again System Idle Process
percentage of CPU time I am getting is 0.

Can anyone tell me a way to refresh the WMI call from C# ? Or how can
I make this VBscript work from C#? Is there any other way to get
percantage of CPU Usage?
Please help me to solve this issue

5. The cpu usage is increased between com and atl

hello everyone.

i made a singleton com with sink.
then i use the com in C# with sink.

-- win32dll -> atl com -> event of atl(if i don't use this code, it's ok) -> 
C#

so i wrote my sample code below.
1.the client  call the function of com in thread.
2.the function in COM will fire to C#
then the cpu usage is increased.
how to solve this kind of problem.
i have to call the function of com continuely, 

do you have any idea to solve this kind of problem.
please , teach me ...

-- Client Side -
 i called a function of com from client in  thread.
		SetValue("AAA", "BBB", __Int, chBuffer);

		SetValue("BBB", "CCC", __Int, chBuffer);

-- com side --
  SetValue(BSTR A, BSTR B, int i, BSTR C)
{
   Fire_Event();
}

-- C# Code
m_easyBridege.OnSetValue += new 
_IEasyBridgeEvents_OnSet(easyBridege_OnSetEventId);

void easyBridege_OnSetEventId(string A, string B, int i , string C)
{
----
}

best regards.

6. CPU usage max'd out in ".NET SystemEvents" thread - CSharp/C#

7. CPU usage 100%

Hi!
While working in c# after say 10 minutes , the CPU usage increases to 100% 
and the framework ide hangs for a couple of minutes.
The CPU usage touches hundred as soon as I switch between Design view and 
code view.
I have Win XP SP2.

Any solutions?
