Hi Danny, The identical code has no unbalanced lock/unlocks when used on an independent database. Only when it's passed its own database does it get the underlock error. And in that case, I've tried changing the number of locks and unlocks, and it makes no difference.
I've seen this problem for years, going back to OS 3.1. It seems that no amount of locking or unlocking saves the app if it has opened its own database. If anyone out there has created code that reads from its own database and doesn't have that problem, please email it to me. My one line of hope left is I'm going to see what happens if I don't lock any of the code records, but just the extra data records, on the hope that maybe the PalmOS only locks records it's actively running code from. - jeff --- In [EMAIL PROTECTED], "Danny Wong" <[EMAIL PROTECTED]> wrote: > HI Jeff, > > this means that you have overlocked a record or resource and then > you try to unlock it again. > > Look over your code and double check make sure the combo lock/unlock > are there. > > regards > > danny > www.toysoft.ca > > > > -----Original Message----- > > From: [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED] Behalf Of Jeff > > Diamond > > Sent: Tuesday, March 25, 2003 12:01 PM > > To: Palm Developer Forum > > Subject: Opening the current App database causing crash on exit.. > > > > > > I have a program that reads data from a PRC database.
