protecting a file
 

Hi everybody,
I've written some VBA code to send certain data to an Excel file which
somewhere in our network, I deally I want to make the file Read/write
protected and only accessable through VBA . Something like remove read only
property anytime I want to send a new record to Excel and after I finish the
process then make it read only again.
What is the best way of doing this?
