MDI，打开子窗口后，父窗口的按钮覆盖在上面，除了隐藏有没有其他的办法？

[swpisw]

如果是隐藏，关闭子窗口后怎么把父窗口的按钮显示出来？父窗口怎么监听子窗口的关闭事件？

'打开的时候加一句
dim f as form
AddHandler f.FormClosed ,Addressof ChildClosed

'然后添加方法
public sub ChildClosed(sender as object,e as eventargs)
    '这里就是子窗体关闭时触发的事件。
end sub

Public Event closefather As childclose
Private Sub Form1_Closed(sender As Object, e As System.EventArgs)
RaiseEvent closefather()
End Sub
Public Delegate Sub childclose()
子窗体：
Dim ff As New Form1()
ff.closefather += New childclose(Me.closethis)
ff.Show()

Public Sub closethis()
Me.Close()
End Sub

这个用模式化窗体不就可以了。。。。。。
