System.Diagnostics.PerformanceCategory question

[Merrion]

All,

I have created a custom performance category thus:-

Dim CounterDataCollection As New CounterCreationDataCollection()
'\\ Create the counters and set their properties.
Dim cdCounterTotal As New CounterCreationData()
Dim cdCounterEMF As New CounterCreationData()
cdCounterTotal.CounterName = "Spool files read"
cdCounterTotal.CounterHelp = "Total spool files read"
cdCounterTotal.CounterType = PerformanceCounterType.NumberOfItems64
cdCounterEMF.CounterName = "EMF Spool files read"
cdCounterEMF.CounterHelp = "Total EMF spool files read"
cdCounterEMF.CounterType = PerformanceCounterType.NumberOfItems64
'\\ Add both counters to the collection.
CounterDataCollection.Add(cdCounterTotal)
CounterDataCollection.Add(cdCounterEMF)
'\\ Create the category and pass the collection to it.
PerformanceCounterCategory.Create( _
"Spoolfile reader", "Printer spoolfile reading perdormance",
CounterDataCollection )

How do I now send data to these performance counters?...i.e. how do I create a new PerformanceCounter object refering to these counters?

Thanks in advance,
Duncan
