(from What's New in Visual FoxPro 8, page 134)
For a CursorAdapter instantiated in code, the Init event fires before all
others, as you'd expect.
But for a CursorAdapter in the DataEnvironment of a form, the event order is
different:
*
*
*Event Order For a CursorAdapter in the DataEnvironment of a form:*
DataEnvironment.OpenTables */* Is this right,
does DataEnvironment.OpenTables fire before DataEnvironment.BeforeOpenTables
?
DataEnvironment.BeforeOpenTables */* OR should this
line read as CursorAdapter.BeforeOpenTables ?
CursorAdapter.AutoOpen
CursorAdapter.BeforeCursorFill
CursorAdapter.CursorFill
CursorAdapter.AfterCursorFill
CursorAdapter.Init
DataEnvironment.Init
Thanks,

http://fox.wikis.com/wc.dll?Wiki~BeforeOpenTables and
have some suggestions.
However, the absolute best way to be sure is to stick a DEBUGOUT in
each method or walk it through using event tracking to be absolutely
sure.

Chuck,
The way I would determine the firing sequence.
Build a simple form with what you need to learn.
Open the Debug window. Tools - Event Tracking. Turn everything, save mouse
movements, and run your form.
Read through the events.

Thanks, found my copy of Hacker's Guide 7, will plow through that chapter
ASAP.

I believe that OpenTables fires before BeforeOpenTables, because it
calls BeforeOpenTables.
Seems weird if you use colloquial english logic, but makes sense from
the point of view of VFP.
When the DE calls the OpenTables method, the first thing this method
does is call the BeforeOpenTables method to know whether there are
things it has to do before opening the tables, like for instance,
establish the path.
I think I read this in some of the guru's books on VFP (and I've read
them all !!)
