I have changed to the ToDoDB and it reads the records out of there fine and
writes them out to a file. Is there something that one needs to know about
creating databases using CodeWarrior 6 Lite as far as the record structure
goes? The record should consist of a series of bytes since I am using the
DmWrite( precord, offset, pfield, StrLen( pfield ) );
method. So shouldn't I be able to just do a byte read against this record
somehow?
The record from the textcond.java example is type MemoRecord. MemoRecord
has a _getBytes method.
I have used the syntax from the _getBytes method
byteOut = new ByteArrayOutputStream();
dataOut = new DataOutputStream(byteOut);
rec.writeData(dataOut);
data1Out.write(byteOut.toByteArray(), 0, (byteOut.size() - 1));
dataOut.flush();
dataOut.close();
So I am using the following to get the bytes.
// Loop over all records
for (i = 0; i < count; i++) {
// Recond a record
rec.setIndex(i);
SyncManager.readRecordByIndex(db, rec);
// Print it out to file
byteOut = new ByteArrayOutputStream();
dataOut = new DataOutputStream(byteOut);
rec.writeData(dataOut);
data1Out.write(byteOut.toByteArray(), 0, (byteOut.size() - 1));
dataOut.flush();
dataOut.close();
}
Is there a better way?
Please advise

I may be misunderstanding your problem, but it seems worthwhile pointing out
that each database on a Palm OS device can contain whatever its author wants
to put in it. The only major limitation is that each record can contain no
more than 64KB of stuff (actually, a tiny bit less). The structure of each
record in a database can be anything. So, there is absolutely no reason to
assume that the record structure used by the other database is anything at
all like the structure of the MemoDB. In fact, it would be very surprising
if the structure was the same, unless the other db was just a copy of the
memo db.
