If it is a problem of the runtime library conflict, I can probably statically link the VS2005 runtime into my extension DLL and there would be no conflict.

Yeah, that > would > require an extension. I haven't looked at PyMultilter objects. I am just trying to build a 'vector version' of my C function so that it can do batch calculations. For example, for a vector X, I can do for x in X: y=my_func(x) Or I can do Y=my_vector_func(X). The latter is probably much more efficient. That's why I need the extension.
