Re: How to debug/track a record pointer change event?

Set a breakpoint on Recno("alias"), and set it to to break when condition
changes.

The usual culprit in this sort of thing is record movement with the wrong
alias SELECTed. Grids can also be fiddly, causing their datasource to become
selected.

Hi,

I am using VFP9 and have a table called NOTES. I have 3 records in
the table. I position the record to record #2 (I verify this by
doing a WAIT ALLTRIM(:STR(RECNO()) WINDOW and then launch another
form (properties set to show within top-level form). I also launch a
ADOBE PDF document using the SHELLEXCUTE command. When I bring the
focus back to the top-level VFP form, the record pointer for NOTES
has changed to EOF(). There is nowhere in my code on that form that
moves the record pointer (including any subroutine calls). I have
tried to track this in vain but just cannot figure out why VFP moves
the record pointer? The Data Environment properties of this top
level form are set to .F. for auto open and auto close tables.
Is there anway to debug a record pointer move so I can trap the event
and figure out where and why VFP is randomly moving the record
pointer?
Thanks
