我用unittest运行测试用例, 会出现这种错误ele = _AutomationClient.instance().ViewWalker.GetFirstChildElement(self.Element) _ctypes.COMError: (-2147024891, '拒绝访问。', (None, None, None, 0, None))

以管理员权限运行

我也偶尔出现这个问题，使用的pytest，以管理员权限运行无效。

I'm regularly getting this error too, as -2147220991 aka CONNECT_E_ADVISELIMIT. It appears to be related to a timeout, when the controled app is unresponsive for several seconds. Though i could not find any documentation on why exactly this error is generated, my workaround currently is handling the exception by trying the same call again...

在使用Navicat Premium 工具时该问题必现，这个问题是否有解决？ element = _AutomationClient.instance().IUIAutomation.ElementFromPoint(ctypes.wintypes.POINT(x, y)) _ctypes.COMError: (-2147220991, '事件无法调用任何订户', (None, None, None, 0, None))
