Can you elaborate on what/when exactly it is not working? Were you able to get the HEX editor open? Did you find the "DPB" string in the editor? Were you able to change it?
Some 2007 files do use a different setup which won't let you use this trick, but if you're able to see the DPB line, it should work. Note that when things work "properly" you will get an error message when you open the file in XL, which should prompt you for a new password. IT's a this point you should give a simple pass like "1234", save, and then close-reopen the workbook.
Since your blog, I were been re-tried to get it done with the help Hex editor but while find your suggested string the msg occurs as "A pattern was not found"
I would like to admit here, I'm very basic in learner of VBA, I really don't know that technical descriptions.
It will be very helpful if you please guide.
