I have a login page.I want  id and password  should only accept case sensitive value . I am developing the application in ASP.Net code behind C#.Net and Database SQL Server 2005.

Thanks..

I have a login page.I want only case sensitive value allow for login.Please send me the code.

 what does it mean : accept case sensitive ?

it's case sensitive or not ... 

if user name and password in database like---name and pass

If i give NAME and PASS on login page it should not login.

I want only after giving same record as in database like--name and pass

should work.

If you make a normal compare, it s case sensitive

String.Compare(s1, s2)

if you want insensitive

String.Compare(s1, s2, true)

If you are using forms authentication in asp.net 2.0 then setting passwordFormat="Hashed" in web.config will set the case sensitivity, because capital and non capital will form different hashes.

You also have the option of HashPasswordforStoringInConfigFile method of formsauthentication class. Please note in this case passwords are case sensitive but not usernames.

If you are using other methods of authentication then perhaps using cryptography to create crypt of every username/password everytime you store will also solve this issue.
