如何捕获运行时对象上的事件

我正在创建一个运行时带有几个按钮和组合框的表单。

dim f as new form 

(胡说八道)

然后设置按钮AcceptDescription和RejectDescription…
然后设置组合框说明组合框…

然后…

AddHandler acceptDescription.Click, AddressOf handleAcceptedDescription
AddHandler rejectDescription.Click, AddressOf handleRejectedDescription

然后我有这两种方法来捕获单击事件…但无法确定如何引用其他运行时生成的控件。(如果接受则组合框,如果拒绝则组合框)

Private Sub handleAcceptedDescription(ByVal sender As System.Object, ByVal e As System.EventArgs)
  'stub 
  'will need to reference the chosen combobox value here 
  dim acceptedDescription as string = descriptionCombo.selectedValue .tostring  
End Sub
Private Sub handleRejectedDescription(ByVal sender As System.Object, ByVal e As System.EventArgs)
  'I want to close the runtime created form here, but can't reference it
  f.close()
  'and return user to main form
  Me.Focus()
End Sub
