How is your method defined in the type library? Not what
#import generates, but the actual type library. You can use
OleView to inspect it.

Hi, no, I'm working on Windows Server 2003. And it all works if I pass
either
an array of primitive types such as strings or Int64's, or if I pass a
single
custom structure. Things break if I combine using a custom structure with
using arrays. Passing a safearray of custom structures to the unmanaged
client doesn't work.

Are you by any chance trying this on Win2K? It doesn't
support 64-bit integers in Automation.

Never mind that I made fields private, doesn't work either way. Below
is a
piece of the header file generated from teh type library. To me this
looks
perfectly valid and I have no clue what's going on.

struct __declspec(uuid("2ac5e284-1855-300e-bb24-28a51e6ffa37"))
ObjectID
{
   __int64 identifier;
   long type;
   long attributes;
   LPSTR name;
};

struct __declspec(uuid("ef585848-5d81-30fb-a8ac-0d797b977f26"))
IService : IDispatch
{
     virtual HRESULT __stdcall GetObjects (
       __int64 context, SAFEARRAY * * objects, VARIANT_BOOL * pRetVal )
=
0;
};
