关于VB.net动态控件问题

动态创建一个窗体怎样在这个窗体中创建动态控件（比如按钮）又怎样写这些控件的事件
窗体是动态添加的，2楼的只有动态控件的写法啊。我的意思是本来工程里面有一个可见的窗体F1，然后再动态创建一个窗体F2…再在这个动态窗体上创建动态控件，用addcontrols前面应该用F2还是F1？

Answer 1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim bt As New Button
Me.Controls.Add(bt)
AddHandler bt.Click, AddressOf bt_Click
End Sub

手动添加如下 也可以是其他事件 :
Private Sub bt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
MessageBox.Show("asasdsadad")
End Sub
'-----------------------------
原理是一样的,Button1为动态创建F2

Dim F2 As Form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
F2 = New Form
F2.Owner = Me
F2.Show()
End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim bt As New Button
F2.Controls.Add(bt)
AddHandler bt.Click, AddressOf bt_Click
End Sub

Private Sub bt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
MessageBox.Show("asasdsadad")
End Sub

Answer 2

Controls.Add 可以不
