Thanks Joost for the answer.
I forgot to mention that i am using Lazarus trunk (0.9.29 rev 26602) with
fpc 2.5.1.
A perfect example that this information is necessary. Now I wrote a
complete mail with useless information. (My last email that is)
I just mentioned TClientDataset because of others said here in the list and
in Lazarus forum.
My concern is that the component seems to be incomplete e can cause some
user headache and needs to be bug reported.
If it is available in component palette, IMHO, it could offer more in design
time, and not assume
that the final user will know that he must do all the stuff in code.
BTW, if someone has some sample of its use, please send it to me.
Thanks in advance.
There are a lot in packages/fcl-db/tests. But maybe not very 'easy' to
understand.
I now remember a bur-report that looks like your story. Someone tried to
create a dataset using the fields definitions. But that is, afaik, not
possible. Also not with a TCLientDataset. (If this is possible using a
TClientDataset, please tell me. In that case I have some coding to do)
If you mean fill up FieldDefs, and call 'CreateDataset' : Yes, you can.
You can even do it with Persistent fields present.
When I wrote 'fields definitions' I meant the definitions of the several
TFields in the fields property. Not the FieldDefs.
Sorry for the confusion. It is already possible to use the TFieldDefs to
create a dataset. But it is _not_ possible to create a dataset based on
TFields. So that's ok?
That's OK.
Creating the necessary fielddefs based on TFields would be a no-brainer,
though.
Michael.
