如何在VB6中实现动态控件的事件处理？有任何想法吗？
最简单的方法是声明与控件类型相同的模块级变量,并使用WithEvents关键字.例如
@H_301_5@Option Explicit
' Declare object variable as CommandButton and handle the events.'
Private WithEvents cmdObject As CommandButton
Private Sub Form_Load()
'Add button control and keep a reference in the WithEvents variable'
Set cmdObject = Form1.Controls.Add("VB.CommandButton","cmdOne")
cmdObject.Visible = True
cmdObject.Caption = "Dynamic CommandButton"
End Sub
'Handle the events of the dynamically-added control'
Private Sub cmdObject_Click()
Print "This is a dynamically added control"
End Sub
如果您希望能够通过一个中心例程处理来自许多不同控件(可能是不同类型)的事件,则会有更复杂的变体.
