点击父窗体form1工具栏“运行”按钮，使子窗体form2中的timer1运行： form2.Timer1.Enabled =true 为什么不行？
'Dim NewMDIChild As 绘图Private Sub Main_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim NewMDIChild As New 绘图
NewMDIChild.MdiParent = Me
NewMDIChild.Show()
End Sub
Private Sub 运行TButton1_Click(sender As Object, e As EventArgs) Handles 运行TButton1.Click
NewMDIChild.Timer1.Enabled = True
End Sub
不行？
