Thanks for the link Larry. I am going to study that white paper.

What does not seem obvious is how A VFP COM, implementing EventHandler(), raises an event AT the [VFP] client that instanciated it.

It seems EventHandler's domain does not extend beyond the COM. Is there something I am missing? How is a COM event via EventHandler, communicated to it's client?

Right now [it seems], the only way to do that is COMRETURNERROR. I nned to read - but what would be really nice would be an "ON EVENT" and a "COMRETURNEVENT". Why beat around the bush with all this "only fires inside a com that contains an OCX control"?

>>Anybody have or know where I can get any samples regarding Excel and BindEvent()? OR, any way I can keep track of a VFP object referencing Excel.Application when the user closed Excel? Thanks,

>John,
>BindEvent only works with VFP internal events , not COM events. For that you need to use the EventHandler function. See Calvin Hsia's artcle http://msdn.microsoft.com/library/en-us/dnfoxgen7/html/vfpandcom.asp for an example of using VFP with Excel.
