所以请帮帮我...
上面我共享了用于将文件下载到xls文件的代码.
1)前往www.google.com或www.bing.com
2)输入"flex Error#2101"，然后按return
比将代码复制/粘贴到您创建的问题中所花费的时间更少
他们说人们不能再写软件了....

Above i have shared code for downloading a file to xls file.
解决方案
Have you even tried finding this out yourself, don''t want to be mean but try this
1) Go to www.google.com or www.bing.com
2) type in "flex Error #2101" and press return
it would have taken you less time than copy/pasting your code into the question you created
and they say people can''t write software anymore....
regards,
这篇关于Flex中的错误#2101的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
