Question Twain - Total Files Scanned

[knockyo]

Hi All,

Currently Im using Accusoft SDK to develop a system for scanning document files. Right now Im facing a problem with the current situation as below,

FYI, I'm using the Twain Scanned EventArgs

Question:
1) How can I count total all document files has been scanned?
OR
2) How to detect which is the last files is scanned?

Conclusion, I need to get total files the users already done scanned.

Thanks your contributed ideas.
