You can't do this purely in VFP, as it involves a callback; VFP does not have the capability of providing a callbak address for a piece of VFP code. You can handle this in one of several ways; an ActiveX control can return a callback address as an integer through one of it's methods, and that can be used to generate a callback to the ActiveX which then raises an event that VFP would respond to; you could use the same sort of strategy using an FLL or DLL. IAC, it will involve coding something in some part not in VFP, or using something that someone else wrote in a product other than VFP that supports publishing a callback address and is able to raise an event.
