Re: Secure store
Tech-Archive recommends: Fix windows errors by optimizing your registry
Steve,
Not that I'm aware of. Encrypting the SDF file makes it secure, but for a
secure way to store the password for accessing the SDF, you'd need to
encrypt that too. You could even use a simple text file or registry setting
once you've encrypted the contents. Check out the Crypto API wrappers on
www.opennetcf.org for code.
