Hi All,
My program is generating reports in excel format which contains 8 sheets. It is batch program to pick up the request from the queue, generate the reports, and send them to the user. And 4 sessions are running at the same time to process the report as many as possible as fast as possible.
A few days ago, I found that if "something" is copied in clipboard outside of the program while below program is running between "copy" and "paste", then that "something" is pasted into the final output file instead of the sheet copied in the program, which is not correct. (It means while "A" session is generating a report, other sheet generated by session("B") is pasted into the excel generated by session "A")
I could re-generate the error by copying other sheet manually while debugging after copy and before paste.
Is there any way to avoid it? Using a shared clipboard at the same time is the problem here. but I can't find solution.
Please advise. Thank you in advance.
