How to call Win32Shutdown method in a proper way

Does anyone know how to call Win32Shutdown method of Win32_OperatingSystem class.

Here is what I have got so far:

VB Code:

Dim OSClass As New ManagementClass("Win32_OperatingSystem")
 
        ' Get an input parameters object for this method
        Dim inParams As ManagementBaseObject = processClass.GetMethodParameters("Win32Shutdown")
 
        ' Fill in input parameter values
        inParams("Flags") = 2
        
        ' Execute the method
        Dim outParams As ManagementBaseObject = processClass.InvokeMethod("Win32Shutdown", inParams, Nothing)

I got an error 'invalid method Parameter(s)' when it reached the last line InvokeMethod. What I want to do is just to shutdown the machine using VB.NET.

anyone????

if you want to use Management object , here's a link ( in C# but easy to understand )
ShutDown Windows with System.Management
although i prefer to use ExitWindowsEx , an example in vb6 ( but easy to translate to .net can be found here...ExitWindowsEx to shutdown windows
if i get chance sometime i'll throw an example together ( but not sure when cuz of feeding duties etc... :p )

Thx a lot, thats solved the problem.

no problem :)
