performance counter problem

[Dirk Reske]

Hello,

I have following code:

[Dirk Reske]

sorry...

following code:
PerformanceCoun terCategory cat = new PerformanceCoun terCategory("Pr ocess");

foreach (string instance in cat.GetInstance Names())
{
PerformanceCoun ter counter = new PerformanceCoun ter("Process"," %
Processor Time",instance) ;
this.listBox1.I tems.Add(instan ce + ":" + counter.NextVal ue());
}

why does counter.NextVal ue() allways returns 0??

"If the calculated value of a counter depends on two counter reads, the
first read returns 0.0." [from documentation]

Perhaps you're really looking for counter.RawValu e?

can someone give some example code, how I can read out the cpu usage of each
running process?
Its in the PerformanceCoun ter Category "Process"

thx
