解决:服务器出现意外情况。 (异常来自 HRESULT:0x80010105 (RPC_E_SERVERFAULT))的解决方法

         最近做的一个项目要求生成Word格式的报告,调试过程中总是出现"服务器出现意外情况。 (异常来自 HRESULT:0x80010105 (RPC_E_SERVERFAULT))"的错误,郁闷了我好几天,最后发现竟然是

WordApp.Documents.Add(ref Nothing, ref Nothing, ref Nothing,ref Visible)

最后一个参数的问题,在此句之前我把Visibale设置成false了,因为我不想在程序生成word文档的时候让用户看见word界面,后来发现即使Visible=true用户也看不到Word界面,
解决方法:Visible=true,能正常运行了,一切OK!
