MDI Parent and children...

[Mothra]

Is there a way for an MDI Child form (well call it Form1...) to poll the parent and see if there are any other child forms (instances of Form1...) open? I am trying to disable a toolbar button if there are no other "like" child forms open...

An MDI Parent form has an MDIChildren property, you could searh that.

Child forms

 

Yes but, I need to determine what form the remaining child/children forms are (e.g. Form2, Form3, or whatever...). What I want to happen is to disable a toolbar button and a menu command if there are no more of a certain form. I just can't seem to tell what is what in the .MDIChildren property.

If you want to see if a certain type of a form is opened then you could do this:

Dim f As Form
For Each f In Me.MdiChildren
   If TypeOf f Is Form3 Then
       'do something if a form is of the Form3 type
   End If
Next

TypeOf

 

TypeOf worked great. Now I can't get to the toolbar button on the MDIParent form to disable it. Any ideas?

Cast the MDIParent object of your mdi child to a type of the parent and then access the toolbar:

DirectCast(Me.MdiParent, ParentType).Toolbar1.something()

That was it. I can not thank you enough!
