Hi guys..
yes I did it again.
I overlocked a chunk but can't find the mistake.
The problem is that the error occurs only every 13. time I'm running my
program.
I know that you can only lock a chunk 13 times, but I thought that the OS
woul free all chunks that had been used by an application when this
application
is closed.
So probably I forgot to unlock a chunk somewhere, but I can't find this
chunk (after
having looked for it for about 13 hours)
Is there any possibility to show me the number of locks of a chunk?
Ok, here is another problem, in the following code that should iterate
through my
database I can put MemHandleUnlock(recordH) in the first position (which
doesn't make
any sense, but it works) but I can't put it into the second position. If I
write it there, the emulator
just crashes with the message "Free Handle"
Any help?
Many thanks, Dyk
