Best/Right approch for master/Detail

[louis]

One more word though: I don't know your requirements.

I also construct the invoice in the same way and assign the number from the server in a trigger BeforeInsert of master table.

My approch all or nothing is because the invoice update the quantity of items in depts, update customers credit and so on... and then for the legacy because of the origin in the use of paradox

Thanks

LGPL, our code is not open

Just a quick question... I'm far away from completely understanding all conditions of licenses (or being a lawyer) but according to LGPL changes made to the original source must be made public, no?

I assume that the LGPL has similar restrictions as the GPL. As far as I remember, oit says that IF you distribute the software, you have to distribute it with the source code included. Soo.. as long as they use Zeos as a basis for an internal project they are fine. If they decide to distribute it, they would have to give their modified Zeos to the people they give their software to.
So - you don't have to make it public but you have to give it to the people that you give your software to.

Ok - that is quite a lot.

Don't worry - a legacy in Paradox doesn't need to be bad. So it sounds like your users already know that aproach. So it is the right way to go

we are not modifying the library in any way and not deriving from library classes it was prohibited by our layers

I mean this topic is kind of dead, it's none of my business and I'm sure noone will enforce any legal action but this comment kinda contradicts your statement:

rewrote a huge part of zeos 7.x to prevent that

Again, I consider the topic closed. Starting a legal or any other inflammatory discussion is completely out of my interest.
