child forms

I'm using this code in my parent form to check if child forms are open, if they are, then I make them the active form. I also open child forms from other child forms. How do I check to see if a form is already open if I'm opening it from another child form?

thanks

Code:

---

Dim blnFound As Boolean = False
            Dim frmChild As Form
            For Each frmChild In Me.MdiChildren
                If TypeOf frmChild Is frmAccountMgmt Then
                    frmChild.Focus()
                    blnFound = True
                    Exit For
                End If
            Next
            'If form not already loaded then load form
            If blnFound = False Then
                Dim frmaccountmgmt1 As New frmAccountMgmt()
                frmaccountmgmt1.MdiParent = Me
                frmaccountmgmt1.Show()
            End If
            Exit Sub
