以下的参数注释是我自己加的，谁能提供下具体的参数使用说明，急！
最好能是包括连接和异步读写函数的使用说明，和参数说明
Public Sub GroupObj_DataChange(ByVal TransactionID As Long, ByVal NumItems As Long, ClientHandles() As Long, ItemValues() As Variant, Qualities() As Long, TimeStamps() As Date)

'TranscationID 处理ID
'NnmItems 标签数量
'ClientHandles 客户端句柄
'ItemValues 标签的值
'Qualities 质量代码
'ItemValues时间戳
' MsgBox ("HAHA!")
'form_configuration.Label7.Caption = opc.GroupObj.OPCItems(12)

'Dim i As Long
'For i = 1 To NumItems
'Edit_OnDataVal(i - 1) = ItemValues(i)
' Edit_OnDataQu(i - 1) = GetQualityText(Qualities(i))
' Edit_OnDataTS(i - 1) = TimeStamps(i)

'Next i

End Sub
