Easy Ways to Make Login Case Sensitive in Visual Basic. Maybe some of you are still asking what is Case Sensitive? Case sensitive is a method of distinguishing lowercase and uppercase (capital) letters. This function is usually found in password typing procedures or certain programming language structures. here we will apply in the Visual Basic programming language.
For those of you who have practiced creating a Sales Application login form with VB .NET, so if you log in using lowercase or uppercase letters (Capital) then there is no effect. In other words, as long as the login password is correct, you don't need to worry about upper or lower case in the database. But if you want your application to be more secure, then we recommend that you use the case sensitive method.
The case sensitive method is intended for more detailed security so that the application is safer from people who are idly logging in with your account.
If you are using a SQL Server database, then you can make or set the SQL Server itself. You can do this by:
Please login to your SQL Server database
Then select the database that you have created.
For example in the table: TBL_ADMIN, there are fields: KodeAdminm, NamaAdmin, PasswordAdmin and LevelAdmin.
If you want a case sensitive password, please select or click PasswordAdmin
Then in Column Properties, please look for the collation
Select Windows Collation
and the Case Sensitive Checklist as shown below:
To practice it, please do a login practice like the Sales application that I have made a tutorial on on this javanetmedia web. then please log in by changing the lowercase and uppercase letters. If it is not the same, it is guaranteed that you can log into your application :)
This is how to make a sensitive login case in Visual Basic, I hope this is useful for you.
