I have a mdb file which have VBA Project and this VBA Project is protected with password. I have forgotten the password. I've found solution that change DPB to DBX but in file there is no DPB in HEX Editor.
Unfortunately, no one on this forum can legally help you in this sense: While we are not calling you anything at all, we cannot prove that you own the file in question. In the USA and in the UK, it is a felony to participate in breaking into a database and might also violate certain regulatory statutes regarding personal privacy. You can do a web search on your topic but we cannot really help you on legal grounds.
