<p class=MsoNormal>Hi,<br>
<br>
Is there any other way to free up memory consumed by a form containing a lot of
components, apart than free or FreeAndNil? I have code piece which is like on a
button click in one form A it calls execute method of another form B which
basically creates an object does its' work and then gets freed up by using
FreeAndNil, within try - finally - end block. <br>
<br>
What is baffling me is even after calling free, the memory is not freed. I have
tried using Release but its giving me Access Violations which I guess due a
large number of components placed on the form. I have read the delphi 2005
documentation ( I am using D2005) and it says for a modal form it hides it when
the form is closed. But, in my case the formStyle is set to fsNormal. Also I am
passing Nil as a parameter while creating form B to make sure I am the one
responsible for freeing up the memory. <br>
<br>
This is confusing me a lot.<br>
<br>
Any pointers please...<br>
<br>
Thanks!<o:p></o:p></p>
