Vlad,

I snooped through the ocx with a hex file viewer and couldn't see any telltale signs of what language it was written in. The OCX is supplied with Win95, there's no MSKB articles of problems with them and VFP. I may have to make this a VFP6 component.

>That's true. But it may work at runtime. Did you try to contact the producer? Do they have any explanation? Do you know in what language were the controls developed?
