VBA Password Overwriting

I need either visual basic source code or a VC++ DLL that can be used be visual basic that will open any VBA file saved in Office 2000 or higher and either decrypt the password or overwrite it with a new password that the user can specify. Such documents that use VBA passwords are Excel, Word, and Access. This code does not need to work for VBA files saved in office 97 or lower. Only 1 function is necessary: 'If decrypting password Result=GetVBAPass(Filepath) ' GetVBAPass returns a string value 'If overwriting the password Result=GetVBAPass(Filepath,NewPass, ConfirmPass) 'GetVBAPass returns a true/false value if successful. If it is not possible to let the user specify the new password, then overwrite it with a hard-coded password in the source code, and let me know what it is. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform All Windows.
