Tips & Tricks:

Please add some!

Since you can't use UInt32 constants in VB.NET, here is one way of passing in a value for dwDesiredAccess

    Const GRANTED_ALL As String = "10000000"

    ret = DuplicateTokenEx(Token, UInt32.Parse(GRANTED_ALL, System.Globalization.NumberStyles.HexNumber), sa, SecurityImpersonation, TokenType, DupedToken)
