,我的監控應用程序因無明顯原因而死亡。它看起來像「mshtml.HTMLDocument」資源不可用。任何人都有類似的經歷嗎?提前致謝。WatiN不時拋出「無法投射COM對象」異常

錯誤消息:

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)).

感謝您的報告。我已經對演員進行了重新嘗試。這個例外可能是由時間造成的。希望重新嘗試將解決它。將成爲下一個版本的一部分或從SourceForge獲取最新代碼。
