Also, maybe, there are things going on in that VB code that may be unnecessary to what Eylon is trying to do? I think the answer to the original question requires more information about the DLL and how it operates.

So, now you are preempint my next question. Can I "reach out" to the VB app from VFP? And, forgive my ignorance - what is VFPCOM and how do I use it?

The dll has a bunch of functions that read trading data from our SE and transmits it to various (software) clients PB etc. we have an app in VFP that currently reads data through DDE which is very slow - so we want to upgrade it to this.
