WatiN“无法转换COM对象”exception
我的监控应用程序不时会因为没有明显原因而死亡。 似乎“mshtml.HTMLDocument”资源不可用。 其他人经历过类似的事吗? 提前致谢。
错误信息:
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'.

谢谢你的报道。 我已经重新尝试了演员。 此exception可能是由时间引起的。 希望重试能解决它。 将成为下一个版本的一部分或从SourceForge获取最新代码。
