What is the equvelant to "As Any" in VB.Net? I'm trying to use the NetMessageBufferSend API and It won't work as followed..

Private Declare Function NetMessageBufferSend Lib "NETAPI32.DLL" (yServer As Any, yToName As Byte, FromName As Any, yMsg As Byte, ByVal lSize As Long) As Long


The "As Any" isn't an option. Should I decalre them objects?
