[SOLVED] Strange things closing form

[Kyjan]

Hi,

i found a strange error. When I try to close the form using the red x in the upper right corner in windows, i got some strange error messages. I tried to write an event handler (onclosequery) to close all open dataset, but this is not the solution.
Any idea?

Thanks,
Kyjan

Which are the messages?

Well, it is not problem with closing empty Form but you have more components there.
You should give here more info or (better) code or simplified compilable project.

Blazen, thanks.
I don't know what details do you need. It is a lawyer office program which can handle all the datas of clients, mails, deadlines, and cases. It uses tsqlite3dataset (3 of them) and other data handling object.
Is it possible that I'll give you the whole code?

Thanks,
Kyjan

I don't work with Tsqlite3dataset. The AccessViolation error you posted means that you try access some memory which is already freed.
So important is what you have in events: OnClose, OnHide, OnDeactivate.

Thanks for the idea! I have written in OnClose event a Halt; and now everything is all right!:)))
