PARAM NAME 對應的事件?(編號：7855)

＜OBJECT classid="clsid:24.....＞
＜PARAM NAME="LOGVAL" VALUE=3＞
＜/OBJECT＞
以上使用ie編輯,那至＜PARAM NAME..時對應的VB active x control 事件是什麼呢?
以下是 VB active x control code
Option Explicit
Public LoginID As Integer
Public vNewValue
Public Property Get LogVal() As Variant
LogVal = LoginID
End Property
Public Property Let LogVal(ByVal vNewValue As Variant)
LoginID = vNewValue
PropertyChanged "LogVal"
Refresh
End Property
