VarPtr equivalent?

The structure PRINTER_NOTIFY_OPTIONS_TYPE has a pointer to a variable length array of 16 bit integer flags as it's last member. In VB-Classic I filled this by using the VarPtr keyword....how do I go about doing this in VB.Net?

i.e.

VB Code:

Private Structure PRINTER_NOTIFY_OPTIONS_TYPE
     Dim wType As Int16
     Dim wReserved0 As Int16
     Dim dwReserved1 As Int32
     Dim dwReserved2 As Int32
     Dim Count As Int32 '\\Number of elements in the array
     Dim pFields As Int32 '\\Pointer to the array
End Type

which is populated....

VB Code:

Dim arTypes(0) As Int16 
arTypes(0) = Job_Notify_Indexes.JOB_NOTIFY_FIELD_STATUS
 
With pTypeJob
    .wType = Printer_Notification_Types.JOB_NOTIFY_TYPE
    .Count = 1
    '.pFields = ???? (was VarPtr(arTypes(0))
End With

Thanks in advance,
Duncan

VarPtr, ObjPtr, StrPtr, VarPtrArray, and VarPtrStringArray functions
The VarPtr, ObjPtr, StrPtr, VarPtrArray, and VarPtrStringArray functions in Visual Basic 6.0 were undocumented and unsupported functions that could be used to return a pointer to a memory address. Although unsupported, these functions were sometimes used when working with Windows API calls that would have otherwise been inaccessible from Visual Basic.

These functions are not supported in Visual Studio .NET; however, most of the scenarios where they were used can be addressed through new functionality in the .NET Framework. Many of the Windows API calls that were necessary in Visual Basic 6.0 are now encapsulated in the framework; pointer references are no longer necessary.
