I remember the original question was how to get the field names of
a record
Let's assume that we can retrieve the AppInfo block from the PDB
header. If the AppInfo block is defined as
typedef struct {
UInt16 renamedCategories;
CharcategoryLabels[16][16];
UInt8
so far I'm not convinced that we can retrieve the record structure
given an arbitrary pdb along with its AppInfo block.
With good reason--there is typically information about record
structure stored in the Appinfo block.

Oops - typing too fast and not proofreading. Typically there is NO
information. Sorry about that.

Thanks Doug for that explanation. And nice to see ya' after a long

No, things fell apart because you made the assumption the
recordlist info would
follow a 78 byte header. Per the Palm OS docs you need to account
for the
AppInfoBlock, if present, and the SortInfoBlock, if
Hi,
some CSV-PDB Converters store the field names in the AppInfoBlock of a
database. Take a look at DmDatabaseInfo to retrieve the AppInfoBlock if it
is there. Some FileManagers also show you, if a InfoBlock is there so check
this first before you do too much work.

You don't have to know what or why they put something in those blocks, only that
they exist and how to get to the records. See the docs at
Hi there,
Hmmm. So you are using third-party tool for conversions. As Thomas
said in his reply, the names could be stored in header part of the
PDB. You may like to ask it to the implementers of the tool or crack
it out yourself.

AppForge has a dll for reading/writing their PDBs on the desktop. code
looks the same as it is on the handheld, so you could write an
extraction program with Visual Basic to work with the files fairly
quickly.
not that I advocate using AppForge, but the tools are all there.

Viren,
our palm-reader ( in-house
developed utility ) was going for a toss sicne it was assuming that
what would follow after 78 bytes would be really a record header ( b-
bytes)...however, things used to fall apart thanks to AppForge
implementations.
No, things fell apart because you made
