I finally got this VFP COM server working. I can pass it an array from C++ and return data in an array from the server.

As soon as I get this cleaned up, I'll report what finally worked.

>>As a test, I decided to change the data type of the array that I am passing to char instead of byte, and use COMARRAY(..., 11). I had been using COMARRAY all along. So, I don't think that is the difference. In any case, this appears to work.
