As you're probably aware, the password security in Peachtree Complete Accounting 6.0 and later is greatly improved over previous versions. You can now limit access on a screen-by-screen basis. Even better, you can set up a user ID that ONLY allows DDE access. Thus, you can also set the password to DDE. Storing DDEDDE in your app means that if someone happens to trip through your code, they'll only gain access to a password that won't let them do anything at all within Peachtree.
