Password Check (Capital and Small)

nour123

Hi all I have a login form(user name and password) that reads its data from a database, I need to check the password textbox letters case, e.g. if the user wrote "admin" it will be different than "ADMIN"... Is there is any function to do that? Regards...

Hi, I have written a Custom function for that. let me know if it work for you

public bool IsInputMatch(string UserInput, string DataBaseInput) { if(Regex.IsMatch(UserInput,DataBaseInput)) return true; else return false; }

now if you use

  if(IsInputMatch("AdMiN", "ADMIN"))
                MessageBox.Show("Valid User");
            else
                MessageBox.Show("InValid User");

Output : InValid User and for this

  if(IsInputMatch("ADMIN", "ADMIN"))
                MessageBox.Show("Valid User");
            else
                MessageBox.Show("InValid User");

Output : Valid User ---- Let me know when done !!! Good luck !!!!:rose:

Very convenient. :^) You can make a password that matches many different strings... These all show "true": MessageBox.Show(IsInputMatch("Anything that you like", ".*")); MessageBox.Show(IsInputMatch("I mean anything", ".*")); MessageBox.Show(IsInputMatch("Really whatever you want", ".*")); MessageBox.Show(IsInputMatch("", "(hello)?")); MessageBox.Show(IsInputMatch("hello", "(hello)?")); MessageBox.Show(IsInputMatch("asdf", "....")); MessageBox.Show(IsInputMatch("1234", "....")); MessageBox.Show(IsInputMatch("baad", "....")); MessageBox.Show(IsInputMatch("oops", "....")); MessageBox.Show(IsInputMatch("1234", "\\d+")); MessageBox.Show(IsInputMatch("0", "\\d+")); MessageBox.Show(IsInputMatch("987489792364587634582345983745", "\\d+"));
