Again, I have to ask why you need to know this? I cannot see why you would have two entry points to do the same thing. The only, spurious case I can think of is if you were providing an app and allowed a UDF to kick something off, but that seems wrong to me.

Everything that happens in the form is the same in both cases.
Thanks for asking, and any thoughts welcome, but I am not looking to re-architecture the application, just looking for a more elegant way to implement what is there now.
Do you know if it actually possible?
