TOnApplyDefaultValue = procedure (DataSet: TDataSet; Field: TField; var Applied: boolean) of object;
The event handler is called for each field with a not null DefaultExpression during insertion of a new record. In this handler you can handle DefaultExpression for some fields yourself if a standard handling procedure doesn’t suit for these needs. You should set Applied to True in order to handle it manually and deactivate standard handling.
FIBPlus has taken the headache out of this project. When I got the current contract, FIBPlus was included on the work computer from the client. I quickly found it easier to use and more powerful than any other Firebird component suite I had tested. When I ran into a problem setting up a persistent calculated field, the tech support people saved the day. I would also add that I tested Zeos, IBX, DBGo, UIB, and other FBconnectors. FIBPlus outperformed all of them, and FIBPlus was run on an older machine than the others were. That was most impressive.>>
