VS 2008 Error "The Requested Performance Counter Is Not A Custom Counter"
May 20, 2010I have this code sample from a book I'm reading which looks to be incorrect:
Imports System.Diagnostics
Sub Main
Dim pc As New PerformanceCounter("PerfApp", "Clicks", False) 'excepiton here
pc.Increment()
counterLabel.Content = pc.NextValue().ToString()
End Sub
There excepion message I get is: The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly. I looked for a property to see if I can set it but couldn't find one.
CPU Performance Counter Always Returns Zero?
Mar 29, 2010In the following block of code always returns zero for the CPU usage. However, if I run it through Visual Studio in debugging mode, do a "Quick watch" on the variable "pcCPUCounter", add ".NextValue()" at the top, and tell it to reevaluate, that returns the varying percentage (eg, 5%, 71%, 16%, etc etc) as the processor utilization fluctuates.
Why would the code always print out zero, but the quick watch doesn't?
Private Sub UpdateCPUUsage(ByVal strSelectedServer As String)
'Performance items come Performance Monitor: perfmon.msc.
'The right-click on columns at bottom and select "add counter" to see list.

Performance Counter Category Name Drop Down List Is Empty?
Jan 30, 2012I wrote a VB 2010 app on a single core processor utilizing performance counters which runs fine. However the release exe fails on my quad core, trapped by the OS on its first access to a PerfCtr. I've loaded VB Express Studio into the quad core
and when running the app in Debug I get this error "Cannot load Counter Name data because an invalid index was read from the registry." Similarly, adding a counter to the app on the quad machine results in the empty drop-downs for category and it sub fields.
where I can get an update to these registry entries?
