I would expect that to work, but it doesn't. I found related info at the link below. Unless something changed since VFP 6, I think I'm gonna have to use the VB wrapper.

>>I'm working with a COM interface that accepts a couple of parameters passed by reference. The component expects the parameters to be of types Variant and Long. Is there any way to tell VFP to explicitly create variables of those types? I realize that VFP variables are inherently variant, but Fox does assign a type to them. A variable that is declared but not assigned is by default a logical variable. I don't know how to create a variant type in VFP. Perhaps type Integer or Numeric will work for the Long variable, but I won't know unless I can get past the "Type Mismatch" error for the variant.

>>The component designers obviously had VB in mind when creating the interface. As a test, I created a VB6 wrapper to the function, and it works as long as I declare the variables as Variant and Long. If I change them to any other type (String, Integer, etc.), it doesn't work. I'd like to do away with the VB wrapper if possible.
