[解决办法]
DIM CKMC AS form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
CKMC= ActiveMdiChild
ActiveMdiChild.Visible = False
BBB.SHOW

END SUB

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
BBB.Visible = False
CKMC.show
