Displaying and Hiding Password Char

Question

I am creating password enable/disable show option in my Windows Forms. I drew this up, and it is not working. Any reason why? There are not errors shown. The password fields are simply not changing when the button is clicked.

   if (textBox3.PasswordChar == '*')
    {
        textBox3.PasswordChar = '\0';
    }
    else if (textBox3.PasswordChar == '\0')
    {
        textBox3.PasswordChar = '*';
    }

' ' - Error: Empty character literal. I think \0 is the closest you can get to this without an error... Giving me an error there. — OracleStart, Jan 26 '17 at 21:51
What are you trying to accomplish by setting the `PasswordChar` to a null character? — , Jan 26 '17 at 21:56
For the actual password to show instead the **** or password chars at TextBox3. — OracleStart, Jan 26 '17 at 21:58

Should be as simple as this. The simple part is remove the other if statement.

        if (textBox3.PasswordChar == '*')
        {

            textBox3.PasswordChar = '\0';
        }
        else
        {
            textBox3.PasswordChar = '*';
        }

if you want to downvote then provide a reason as what I posted works. – Sorceri Jan 26 '17 at 22:00
Wasn't my downvote, but you could have at least stated what was so simple – Sayse Jan 26 '17 at 22:01
Funny part. Still not fixed :(. I don't know who downvoted. Same goes for mine. – OracleStart Jan 26 '17 at 22:06
Then you have other issues and should post the full code. My guess is that you do not set the PasswordChar after the control intitalizes. – Sorceri Jan 26 '17 at 22:07
Oh. I deserve a walk of shame. Sorry for wasting everyone's time. I just saw passwordchar was not filled and UseSystemPasswordChar was on. – OracleStart Jan 26 '17 at 22:13
No worries @OracleStart, it happens to the best of us. – Jan 26 '17 at 22:17
