Hi,
I'm writing a program to send databases through a network
connection. It's working fine with simple palm databases, but I get a
strange behavior with resource databases. When I open a PRC, seems
that it overwrites my program's resources with the ones defined in
the PRC file. For example, if I have an Alert with a string and try
to show it with a PRC database opened, my program shows another
alert, which is defined in the PRC file. Simply opening a resource
database will 'register' its resources, overwriting mine own
resources? Is there a way to avoid this behavior?
After opening the resource database, reopen your application's
database. That will put it back on top of the resource list --
however, if there are resource conflicts, you'll get your apps
resources instead of the new DB's resources.
This problem of an implicit list of resources was fixed in Palm OS
Cobalt's Protein API, but there's no good way to handle this in the
standard Palm OS API.
Ok Ben, thanks for the help.
Another question: What's the easier way to simply copy the
databases' contents (from the PDA's memory, not from a expansion card)
to a remote server, so that I can reconstruct the database as files?
Since Palm's files are not contiguos in memory, I believe the only way
is to get the number of records and iterate through them, sending record
by record, right? In this case, can I handle PRCs and PDBs in the same
way? I mean, can I use DmNumRecords and DmQueryRecord to read PRC's
records, or should I use DmNumResources, DmGet1Resource?
Thanks again,
Luciano
