Not, I download Revision 3878 with TortoiseSVN.

Verified with latest 3877 revision but is the same

Hallo, Do you use persistent Fields? Than i can't handle your trouble.. Yes, I use persistent fields :( With a non persistent field, when the data is visualized on DBGrid or Lookup control works ok, but if data is modified, the field accept double of chars (Field size of database is 20, fieldsize is...

Ops, I'm sorry
I have a mistake, I read the Firebird Types from a wrong page http://www.firebirdsql.org/manual/migra ... types.html instead of http://www.firebirdsql.org/en/firebird- ... fications/ as suggested by miab3 in other tread.

Best regards.

Hallo,
version 7.2 is mature for use in production?

Thanks

Probably the property is designed to be used with no firebird databases. With Firebird, because the fact that SortedFields property refetch all rows on dataset I think is best NOT to use this property. On clients connected by LAN the performances are very very slow even for dataset with very few row...

Hallo, I'm rewriting my application to migrate from BDE to FB. Thinking is best, I used property "SortedFields" instead of using the clause "ORDER BY" in SQL Query and the performance of FB was running very very bad on LAN that the application seems not usable! in local, Instead,...

Hallo, I used EmptyDataSet because I supposed that is the right method for doing my chance but it seems not works correctly. I wish delete all records presents on DetailDataset then repopulate it with a new data with a possibility of cancel those updates. New data can contain old keys or not. This i...

did you update (checkout again) your copy of Zeos from the SVN repository? Yes, in fact I tried both doAlignMaxRequiredWideStringFieldSize that doNoAlignDisplayWidth. I checkout "testing-7.2" branche from repository "http://svn.code.sf.net/p/zeoslib/code-0/branches/". I make a m...

so i did add a TZDataSet.Options enum doAlignMaxRequiredWideStringFieldSize which turns the logic around. Adding this option means reserve a "perfect fit" buffer, whereas missing the option (default) should align TWideStringField.Size to Count of Characters declared in your DataBase. Patc...
