Keep Excel File In Foreground To Allow User To Edit It

[TimTDP]

I need to import an Excel file into Access.
However before I import it I need to ensure that the format of the Excel file adheres to certain rules.
I want to:
1. Open the file from within Access
2. Halt the code in Access until the Excel file has been closed. This will allow the user to ensure that the Excel file adheres to the rules.
3. When the Excel file has been closed, continue with the Access code.

I know how to do step one, but how do I steps 2 & 3?

Thanks in advance
