COMException - Type Mismatch - VARIANT* and SAFEARRAY

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi folks,

I'm trying to call a COM method that has the following signature:

long Foobar(long category, VARIANT* handle_list);

The documentation says that handle_list is a SAFEARRAY of longs (int32) that
will be populated by the function. Tlbimp (regardless of /sysarray) gives me
a signature like:

int32 Foobar(int32 category, ref object handle_list);

The IL uses: object& marshal (struct) handle_list

Is there any way to call this function from .NET? No matter what I seem to
supply, I always get a "COMException - Type Mismatch". I've tried creating
arrays and wrapping them in objects, etc to no avail. It seems that even if I
was able to send over an array, the COM function wants to allocate/fill it,
which is going to cause problems.

Thanks,
-G

At this point, I'm wondering if the best approach would be to write a small
C++/VB library that will accept the raw SAFEARRAY, wrap it, and pass it to
the library.
