WatiN“无法转换COM对象”异常
WatiN“无法转换COM对象”异常
提问于 2011-04-14 22:36:56
有时，我的监控应用程序会无缘无故地死掉。似乎"mshtml.HTMLDocument“资源不可用。其他人也有类似的经历吗？提前谢谢。
错误消息：
14.04.2011 18:26:37 -> Test 1.2 (Subscriber type requests), error: Unable to cast COM object of type 'System.__ComObject' to interface type 'mshtml.HTMLDocument'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{3050F55F-98B5-11CF-BB82-00AA00BDCE0B}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).错误堆栈跟踪：
