Hello again,I hope this time someone will reply me - my problem is that when I try to write a exe application for measuring the cpu usage every time I get the error:
Code:
A first chance exception of type 'System.InvalidOperationException' occurred in System.dll
or
Code:
A first chance exception of type 'System.FormatException' occurred in mscorlib.dll
The code I use is :
Code:
Imports System.Diagnostics

Dim oPerf1 As New PerformanceCounter

oPerf1.CategoryName = "Processor"
oPerf1.CounterName = "% Processor Time"
oPerf1.InstanceName = "0"

Dim I As Integer
For I = 0 To 100
SomeListBox.Items.Add (oPerf1.NextValue)
Threading.Thread.Sleep (20)
Next
And I get the above error,I searched a little in the internet but the most post were for database optimization and so on.
