Following Function documented in msdn gives error : not found (management exception unhandled)?

Question

Public Function GetDiskSpace() As String

Dim diskClass As _
New System.Management.ManagementClass("Win32_LogicalDisk")
Dim disks As System.Management.ManagementObjectCollection = _
diskClass.GetInstances()
Dim disk As System.Management.ManagementObject
Dim space As System.UInt64
For Each disk In disks
If CStr(disk("Name")) = "C:" Then
space = CType(disk("FreeSpace"), System.UInt64)
End If
Next disk
Return space
End Function

It gives error in

diskClass.GetInstances()

I have done it thru msgbox and exception handling too, but can't resolve why getinstances is not found ?

Thanks for answer, can you please help me further ?

Answer 1

One of your management methods has returned a "not Found Exception" You have no exception handling wthin the code.

Use a Msgbox command to find out which command is not working or use exception handling for all commands.

If this is wrong then it is because I do not know VB!
