Hi,
I am about to write a C extension module. C functions in the module will
take and return numpy arrays. I found a tutorial online, but I am not sure
about the following:
1. Can I compile my extension with Visual Studio 2005? My impression is that
I will have to link with numpy libraries, and,

Mostly it's an issue of the C runtime that is used for either compiler

I agree with others that ctypes might be your best path.

Pyrex is a good bet too:

The advantage with pyrex is that you don't have to write any C at all.
You will have to use a compiler that is compatible with your Python buil
