Re: Retrieve 2D Variant Array

You might try dumping the return to System.out to see what type it is?

From groping the code, my guess is that your just getting one dimension of
the result and the type is double[]

There are a couple of places in the C++ code that mention that
multi-dimension SAFEARRAYs are not supported. If the COM server is returning
a multi-dimension SA then you have a couple of options. If you're a C++
coder you might be able to add support yourself. I think I tracked it down
to Transform.cpp, but without running it I can't be sure. You could try
another opensouce tool. You could sponsor someone to fix it. You could try a
comercial tool.
