Hi Dennis,
I'm a little confused by observation 1. Is the size of the array different after the method call? That would seem to indicate a re-dimensioning by the activex component.

I don't have much in the way of more ideas, perhaps loading the array with 0's or chr(0)'s before sending. Have you examined the ActiveX control with the object browser to see if that reveals anything useful? I've dragged an interface on to an open prg or even the command window to see what a method wants and returns.

Good luck.

Gary
