When does the form goes destructed

[Boni]

Hi All,
I have a form, where user can fill some fields and then press "OK". On the
OK-button I have

this->close();
if (this->field1.text==a ) ...
It seems to work. But as far as I understand MSDN the form goes with "close"
not only unvisible but also can be destructed. I am right? What is the
proper way to handle such UI?
Thanks,
Boni

Re: When does the form goes destructed

Boni,

The form will be destructed when the garbage collector does that, however
because that it is a part of the managed code you should not watch for that.

With one exception.
When it is a modal (dialogform), than you can better use
frm.dispose instead of the frm.close

To see if you still can use a form you can test with

Isdisposed

I hope this helps,
