Title is not very good, in fact is like this:
Because want to change some files uploaded to the database, then use OleContainer browsing, but OleContainer can only load ole format flow, so the file opened by OleContainer, get OleStream, then save it to the database

Want to ask if you want to convert OleStream to original format flow how to do?

CodePudding user response:

I just don't know how to turn to send up
