Validate Username And Password?
Sep 12, 2009I had one user in my db and when using this code it validates my username and password, but when I added a second user, it does not validate the second user, only the first one.

What can I do to make sure it actually runs through rows in the db and compare the information in the text box with the information in the database?

Security - Storing Windows Username + Password
Jan 6, 2011I'm writing a backup program for personal (for the moment at least) use.
For some directories (network directories / protected directories) credentials are needed to access them.
I can setup different jobs in the program to run at specific times.
These jobs are stored in an XML file.
I want to also store the usernames and passwords which the jobs will need.
What and where would be the best way to store these?
Changing permissions on the directories is not an option.
