I have successfully saved account details to a .dat file (username, password, account type).the issue is however, that any username works with any password, for example, if the file were "user1 password1 user2 password2".I would be able to log in using "user1" as the username and "password2" as the password, i think i'm missing something?

View 5 RepliesI have a form just like the login form in VB.Net. The usernames are prepopulated on a combobox with datas from the SQL DB backend, and the text box for the password entry is empty. My code is working but what I need help is, for the code to validate the username and password entered against that stored on the SQL DB backend. Like when the user selectes a wrong username but the password entered is correct, there shld be a messagebox like "The username selected is wrong", or if the username is correct and the password entered is wrong then the msg is "The password entered is not correct, please type you password using the right case".

I 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. I removed the first user and added it to my db after the new user, but it did the same. 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?
