UIAutomationClient elementFromPoint VBA错误＆＃34;用户定义的类型可能无法通过ByVal＆＃34;

Question

有没有办法在 UIAutomationClient 中使用 ElementfromPoint 和VBA（EXCEL）

我一直有编译错误：  ＆＃34;用户定义的类型可能无法通过ByVal＆＃34;

Sub Test_ElementFromPoint()
Dim uiAuto As New UIAutomationClient.CUIAutomation8
Dim elmRibbon As UIAutomationClient.IUIAutomationElement
Dim pt As tagPOINT

pt.x = 541
pt.y = 99
Set elmRibbon = uiAuto.ElementFromPoint(pt)
MsgBox elmRibbon.CurrentName
End Sub

如果我不能使用来自vba的elementfromPoint，我可以使用Iaccessible的AccessibleObjectFromPoint来启动我的查询，但是使用它我不能从ElementFromIAccessible获取所有信息（.currentHelpText）
