how to set a text box for inputing password in winforms? Also I want to show \"Capslock is ON\" popup if capslock is on.

I want something like

Answer 1

To make PasswordChar use the ● character instead:

passwordTextBox.PasswordChar = '\u25CF';

Answer 2

I know the perfect answer:

1. double click on The password TextBox.
2. write your textbox name like textbox2.
3. write PasswordChar = '*';.

4. I prefer going to windows character map and find a perfect hide like ●.

   example:TextBox2.PasswordChar = '●';
