Does MdiChild Close remove Reference in MdiParent?

[SprintFlunky]

Simple question but I must not be doing something right.

In Form1:
Dim F2 as new Form2
f2.MdiParent = Me
f2.Show

In Form2:
Me.Close()

If I then loop through the MdiChilden of Form1, f2 is still referenced and if I do a .Show() it will show back up.

How do I destroy f2 in the Form1 class?

Try f2.dispose

See if that works. Close won't remove the reference until the garbage collector comes around.

Dispose actually triggers with a close event and does not remove the reference from Form1. However, after a little more looking around, I found a soultion that works:

in Form1:

If not f2 is Nothing then
f2.Close
f2 = Nothing
End if
Dim f2 as new Form2
..

This allows me to put logic in Form2.Close to perform any wrap up logic before creating a new f2. Not the best looking code, but it should stop memory leaks.

Thanks for the reply.
