!!!!C# Definition:
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto, Pack = 0)] //Platform independent 32 & 64 bit - use Pack = 0 for both platforms. IntPtr can also be used.
    public struct EXPLICIT_ACCESS
    {
        UIntPtr grfAccessPermissions;
        UIntPtr grfAccessMode;
        UIntPtr grfInheritance;
        TRUSTEE Trustee;
    }
!!!!VB Definition:
    <StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Auto, Pack:=4)> _
    Public Structure EXPLICIT_ACCESS
        Dim grfAccessPermissions As Integer
        Dim grfAccessMode As Integer
        Dim grfInheritance As Integer
        Dim Trustee As TRUSTEE
    End Structure
!!!!User-Defined Field Types:

!!!!Notes:
UIntPtr or IntPtr are needed because they change sizes according to platform. If you need to cast to / from, then must keep the size change in mind.
