Database corruption

[Lionscribe]

I have a program that uses a single record database for its data. On the start 
of the applicationam the db is opened, and the record is gotten & Locked. Upon 
exit all is unlocked, released & closed.
problem is that some user, after many months the program starts showing garbage 
data, as if the data is corrupted.
Resetting the Palm usually does not help, but if the user just reinstalls the 
same database, or copies it to the card & then back to devoce, everything is 
fine.
In addition, when there is an Alarm, & we open database read-only, Query 
Record, Lock, Read , Unlock, Close, evrything reads fine.
Is there anyone who can figure thus out?

Re: better timing than TimGetTick?

[Dmitry Grinberg]

on 68k devices tick is 100Hz, on emulator it is 100Hz, on mac
simulator it is 60Hz, and in native arm mode it is 1000Hz

AW: better timing than TimGetTick?

[Harald Schlangmann]

Darren,

 

don't know if I get your question right…

 

The time the event loop takes for one loop differs by the work that is done… A 
nilEvent will typically take less time (less than a tick) than e. g. a 
redrawing (probably several ticks).

As I wrote below, a tick in PalmOS is 1/100s, i. e. increments 100 times a 
second, i. e. 100 Hz.

 

Grüße, Harald

Query :

is the event loop processing being timed at tick intervals, (1 loop pass per 
tick), or

at clock speed of the specific processor?

Re: My app can´t open my Shared Library

[Tiago]

I saw these Shared Library: http://www.bin-people.de/pnoJpegLib/index.html for 
compare whith my Shared Library. The core of pnoJpegLib is similar to my SL. I 
tryed to use the functions bellow for open the pnoJpegLib shared library:
SysLibLoad(...);
MySharedLibraryOpen(...); 
First I installed the pnoJpegLib in my treo 650 and both functions return 
sysErrLibNotFound and the function witch open the Shared Library 
(pnoJpeg_OpenLibrary()) return 0, meaning witch the SL is opened.
After this, I removed the pnoJpegLib my treo, and happen the same of the first.
I´m making the correct procedures for use the SL?
