1. I am sure there is a way to close the ChildForm from ParentForm

Example
I have several (song) albums. Each album has several songs
So.... Album is my ParentForm and each song has each ChildForm (6 songs = 6 ChildForm)
(Album = Directory, Song = file)
When I change the album (to albumX), I will that all the ChildForms those belong to the Album, to be closed
And then open all the Song/ChildForm of the new album (albumX)
Can anybody tell me how to do it

2. If I open a ChildForm that already opened, I want to show a message and Set the ChildForm Active
How can I do this

Thansk in advance for help

Regards
Joachim.

Loop through the MDI parent's 'MdiChildren' collection and close all
forms that belong to the album. It's likely that you will need to use
the 'DirectCast' operator ;-).

Call the MDI parent's 'ActivateMdiChild' method and pass a reference to
the MDI child that should be activated to this method.
