im doing parameterized query whereby the user has to enter id and password. im using access database to store my data and using visual studio .net 2003 to build my app. if the id n password match, data is retrieved. i need help to ensure that password typed is of the exact case as stored in database. that means, if password in database is hELLo23 the user cannot access if he types hello23. how do i do that?
second problem is how can i make it such that user types in password and the password appears like this ********?
finally, how do i let password in database appear in encrypted text so that it is impossible to see the password in text format? i read about hash... do i use that? can i have more details?
