Question : convert c++ delegate parameters for managed code

C++ code:
__delegate UINT32 DelegateCallInUnmanaged(ListData* pLData, WORD* pFieldsArray, UINT32 dwCount);

vb code:
    Public Function status_DelegateInVB( ?, ?, ByVal Count As UInt32) As Int32

How could I convert ListData* , and WORD* in unmanaged code before i create delegate for using in managed .net code?
