[excel] How do I open workbook programmatically as read-only?

This is how I can open an excel file in vbA:

Workbooks.Open(file-path)

is there a way to specify that it should be open as read-only? The files I am opening have a password on them, and I always get the dialog that it can only be open as read only.

Check out the language reference:
