Ok ... I didn't really give you any advise, I was trying to nudge
you in the right direction ... I can see we're gonna need a bigger
nudge ;-)
First -- stop thinking "columns". This isn't your classic SQL database,
or even MS Access. When you hear "database" in the Palm context,
think "file", because that's essentially what they are.
Second, you probably don't want to go passing the handle to a
db record to the Palm GUI library. I know you can, but I tend to
prefer an intermediate "working copy" so that you can implement
"ok" and "cancel" ... if your form directly modifies the record,
"cancel" is a pain in the touchis.
Get your record from the database, initialize the form w/ that
data, then when the form closes either copy the data back from
the form into your record ... or not, depending upon whether "ok"
or "cancel" was tapped.
If you really do want to do in-place editing w/o the intermediary,
look at void FldSetText (). The offset parameter there would
be used to point the (form) field at the proper (data struct) field.
