Release vs. FreeAndNil

[BobRoyAce]

Up until now, when I create a form, and subsequently free it, I use code
like follows:

frmTest := TfrmTest.Create(nil);
try
frmTest.ShowModal;

DoStuffHere...

finally
FreeAndNil(frmTest);
end; (* try...finally *)

I was reading something somewhere about the Release method for forms and it
got me to wondering if I should be doing that instead (e.g.
frmTest.Release). I must say that, as far as I know, all works fine doing
what I'm doing, but maybe that's just dumb luck.

Any insight?

RElease is to be called when you want to free a form from within an event of
that form. Release posts a message to the form so it won't get processed until
after return from the method. Trying to free a form from within say an OnClick
event will cause an AV, calling Release will not. If you are freeing from
outside the context of the form then Free is the correct way to do it.

Too bad TFrames do not have some type of release features. In some cases
it'd be nice to have although for pretty much all of them, some upfront
design work can get around it.

Well, i think it is very easy to add a Release in your frame. All you
have to do is copy procedure Release and message handler CMRelease
from TCustomForm in your frame.

And may be ask this to be added already to TFrame for Delphi 7.
