I want to build an app to do the following:

Part I
-Create a list of files from a specific directory
-Check the "Comments" field in the files properties for values
-If the value is Null then place a check box that is unchecked beside the filename
-If there is a value the check box should be checked.

Part II
-IF the user clicks on the filename it will open it (All files will be PDFs)
-The user will review the file and close acrobat(reader) and then if they check the checkbox beside the file name it will add the username - date - time to the "comments" field of the file properties
-The transaction is logged.

Any help would be appreciated.

Thanks.
