推荐答案
RPC_DISCONNECTED ...可怕的被调用的对象与客户端断开连接问题。有很多原因，看起来你已经用 Excel覆盖了全局变量问题。。你可以把第一个 ReleaseCOM（ReportSheet）在 ReportBook（关闭）下运行吗？另外，请查看。
RPC_DISCONNECTED...the dreaded "The object invoked has disconnected from its clients." issue. There are a ton of causes to this, looks like you've covered the global variables issue with Excel.. Can you put the first ReleaseCOM(ReportSheet) below ReportBook(Close) and run it? Also, check out this.
