[RESOLVED] Disabling the close button on a MdiChild form

I can get this (http://www.vbforums.com/showthread.php?t=351533 ) to work on my main form but not on forms that i set as MdiChildren forms of my main form. How can i adapt the code from that link to disable the close button on my MdiChildren forms ?

Ah nm i found by adding it to the a timer tick event i can make it work

VB Code:

Me.MdiParent = MyForm.ActiveForm
        Dim myMenuManager As New SystemMenuManager(Me, False, SystemMenuManager.MenuItemState.Greyed)

Thanks :bigyello:
