> Could some of the VB experts look at this code and tell me why my VFP implementation is not working correctly. I am woking with a 3rd party set of DLLs and they don't know anything about VFP. The op events fire and work as I would expect. When the Done code fires it's supposed to return some data in the pTemplate object. It returns as all blank.

There is no way to declare this in VFP

Dim WithEvents op As FPRegisterTemplate

this a variable object that raise events, the only way you could use this COM is Compiling it as an invisible at runtime ActiveX Control. Maybe the people who made it can do that for you, that's not such a difficult task.
