Is there an error message?

I would check these:
- make sure the rs is client side and disconnected.
- make sure the rs.state is 1 (open).

I have a working VB program that passes an rs to a VFP COM dll, the difference from your code is that I don't use the Call statement.

>I have a com server written in VFP that employs VFPCOM to convert between cursors and recordsets.
>
>My server method - getrecordset() - to return a recordset to the client works fine whether the client is written in VB or VFP.
>
>The method -passrecordset()- that takes a recordset as a parameter fails when the com server runs in a VB client (see code snippet below).
