Hi
What you going to need is: SQL stored proc to return the newly
created/updated records ID(key), Global array and plenty of patience.

When you add the data into your tree view, assign the return value from
the database into the global array. Lets say your process requires 3
additions before it will work, then run a count for 3 while doing all of
your processing, and validation. Once this has been completed a message
box can be displayed.

I hope I am on the right track from your description, but from my
understanding, this will work.  Please let me know how it turns out.

Cheers
Ary
