Dear Eric,
Thanks for your help. It is very great if you will email me your sample

>You need to use an encrypt and decrypt algorithm to store and check your passwords. If you distribute your app the tables can be opened by anyone but if the data is encrypted it won't be of any use to them. I keep my encryption and decryption code in a class specifically used for security purposes and I keep that source code locked up on the development machine. You can also take other measures like don't name the password field 'password'. There are many other creative ways to secure your passwords. If you need an example of an encyption routine I can email you a simple example.
