Hi,
I have a project which currently consists of Form1, Button1, Label1 and Timer1.
I can run this code with no problem.
I want to add a PerformanceCounter, when I added one and ran it
The project didn't run, I got an error message.
System.InvalidOperationException
HResult=0x80131509
Message=An error occurred creating the form. See Exception.InnerException for details. The error is: Failed to initialize because CategoryName is missing.
Source=DiscMonitor
StackTrace:
at DiscMonitor.My.MyProject.MyForms.Create__Instance__[T](T Instance) in :line 190
at DiscMonitor.My.MyProject.MyForms.get_Form1()
at DiscMonitor.My.MyApplication.OnCreateMainForm() in D:\~VB Trials\DiscMonitor\My Project\Application.Designer.vb:line 35

at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.Run(String[] commandLine)
at DiscMonitor.My.MyApplication.Main(String[] Args) in :line 81
This exception was originally thrown at this call stack:
[External Code]
Inner Exception 1:
InvalidOperationException: Failed to initialize because CategoryName is missing.
I removed the PerformanceCounter, and ran it again, no problem.
I then added a PerformanceCounter again and ran it. Just got the error again.
I don't understand why just adding a control should cause this problem.
