Programmatically connecting to Virtual Server using Visual Studio

Source: microsoft.public.virtualserver

I've got a section of code that works fine with Visual Studios 2003, but
errors out when using Visual Studios 2005. My first guess is that DCOM Type
or how you declare them has changed with the new .NET framework, but I am not
certain.

Anyway, here is the code that I am having troubles with (Straight from the
Virtual Server SDK):

---------------------------------------[ Start of Code
]----------------------------

' Get VMVirtualServerClass instance from a remote server using DCOM
Public Function GetVMVirtualServerClass(ByVal server As String) _
As VMVirtualServerClass
Dim typeVSClass As Type
Dim typeDCOM As Type
Dim objDCOM As Object

typeVSClass = GetType(VMVirtualServerClass)
typeDCOM = Type.GetTypeFromCLSID(typeVSClass.GUID, server, True)
objDCOM = Activator.CreateInstance(typeDCOM)

GetVMVirtualServerClass = CType( _
Marshal.CreateWrapperOfType(objDCOM, typeVSClass), _
VMVirtualServerClass)
End Function

'Get VMVirtualServerClass instance from local server using COM
Public Function GetVMVirtualServerClass() As VMVirtualServerClass
GetVMVirtualServerClass = New VMVirtualServerClass
End Function

---------------------------------------------------[ End of Code
]-------------

Anyway, the probem is when it attempts to make a connection to Virtual
Server it throws an InvalidCastException when calling the function
"GetVMVirtualServerClass." Error message says "Source object cannot be
converted to the destination type since it does not support all the required
interfaces."

Again, that error tells me something changed with either the Framework or
Visual Studios 2005 itself. However, I'm posting this here, because it has
to deal with connecting to Virtual Server 2005.

Anyway, any possible help on this would be GREATLY appreciated. Thanks!

Are you using the local server or remote server version of
GetVMVirtualServerClass?

This hello world sample from your code worked for me in Visual Studio
2005...

Imports System.Runtime.InteropServices
Imports Microsoft.VirtualServer.Interop

Module Module1
' Get VMVirtualServerClass instance from a remote server using DCOM
Public Function GetVMVirtualServerClass(ByVal server As String) _
As VMVirtualServerClass
Dim typeVSClass As Type
Dim typeDCOM As Type
Dim objDCOM As Object

typeVSClass = GetType(VMVirtualServerClass)
typeDCOM = Type.GetTypeFromCLSID(typeVSClass.GUID, server, True)
objDCOM = Activator.CreateInstance(typeDCOM)

GetVMVirtualServerClass = CType( _
Marshal.CreateWrapperOfType(objDCOM, typeVSClass), _
VMVirtualServerClass)
End Function

'Get VMVirtualServerClass instance from local server using COM
Public Function GetVMVirtualServerClass() As VMVirtualServerClass
GetVMVirtualServerClass = New VMVirtualServerClass
End Function

Sub Main()
Dim vs As VMVirtualServerClass = GetVMVirtualServerClass()
Console.WriteLine("Version of Virtual Server is " & vs.Version)
End Sub

End Module
