Owner vs Parent vs ParentForm

What's the difference in these three?
Nov 21 '05 #1

Tom,
| What's the difference in these three?
| Owner vs Parent vs ParentForm

Form.Owner - Is the Form that "owns" this form. For example a modless
Find/Replace dialog would be Owned by Notepad's main window. If you minimize
the main Form, the owned form will minimize, if you restore the main form,
the owned form will restore... Normally used for "tool" windows in SDI
applications...

Control.Parent - Is the immediate control that this control is placed on.
For example an option button placed in a Panel or GroupBox would have that
Panel or GroupBox as its Parent.

ContainerContro l.ParentForm - is the Form that this ContainerContro l is
ultimately placed on, however the Parent of the ContainerContro l maybe
another ContainerContro l, which may have another Control as its Parent,
which may then be a Form. Basically this does a Control.Parent until it
finds a type that inherits from Form.

Hope this helps

dim frm as myform
frm.owner = me

In the myform you can say
me.owner.textbo x1 or whatever

me.ismidicontai ner = true
frm.parent = me
me contains a than a colection of zero or more childs in its
mdichildscollec tion

me.parentform.m enu1 'in a mdi form a menu on the mdicontainer

I hope this helps,

Cor,

| frm.parent = me
| me contains a than a colection of zero or more childs in its

Your example appears to be Form.MdiParent and not Control.Parent.

Hope this helps

OK great, owner provides functionality that ties forms togther when
minimizing and maximizing. But you can reference Parent and ParentForm
from a form class. Can that just be used as another way to tie them
together that doesn't provide any functionality?

Tom,
Parent is a Control to Control relationship.

ParentForm is a Control to Form relationship.

I really don't see how you would see a Form to Form relationship in either
Parent or ParentForm, unless you placed one Form as Child *Control* of a
second Form. Then however your "Form" is no longer a Form, but its now a
Control!

What specifically do you have in mind?

Hope this helps
Jay

I don't have anything specific in mind beyond what Owner offers, but I
didn't understand why Parent and ParentForm were available on the form
class.

How does a "sub-form", i.e. one invoked by another form, determine anything about the form which brought it into existence, i.e., I suppose, instantiated it? I wanted to so something like this ... MsgBox("called by " & Owner.Name) .... but that throws a null reference exception. Parent.Name and ParentForm.Name also throw null reference exceptions. Form1.Name works - but that's not very flexible.
