C# Solutions
Solution 1 - C#
The best way to solve your problem is to set the UseSystemPasswordChar
property to true. Then, the Caps-lock message is shown when the user enters the field and the Caps-Lock is on (at least for Vista and Windows 7).
Another alternative is to set the PasswordChar
property to a character value (* for example). This also triggers the automatic Caps-Lock handling.
Solution 2 - C#
To set a text box for password input:
textBox1.PasswordChar = '*';
you can also change this property in design time by editing properties of the text box.
To show if "Capslock is ON":
using System;
using System.Windows.Forms;
//...
if (Control.IsKeyLocked(Keys.CapsLock)) {
MessageBox.Show("The Caps Lock key is ON.");
}
Solution 3 - C#
To make PasswordChar
use the ● character instead:
passwordTextBox.PasswordChar = '\u25CF';
Solution 4 - C#
Just set the TextBox.PasswordChar property to '*'.
Solution 5 - C#
Just set the property of textbox that is
PasswordChar and set the *
as a property
of textbox. That will work for password.
passwordtextbox.PasswordChar = '*';
where passwordtextbox
is the text box name.
Solution 6 - C#
private void cbShowHide_CheckedChanged(object sender, EventArgs e)
{
if (cbShowHide.Checked)
{
txtPin.UseSystemPasswordChar = PasswordPropertyTextAttribute.No.Password;
}
else
{
//Hides Textbox password
txtPin.UseSystemPasswordChar = PasswordPropertyTextAttribute.Yes.Password;
}
}
Copy this code to show and hide your textbox using a checkbox
Solution 7 - C#
you can use like these "txtpassword.PasswordChar = '•';"
the use location is ...
namespace Library_Management_System
{
public partial class Login : Form
{
public Login()
{
InitializeComponent();
txtpassword.PasswordChar = '•';
Solution 8 - C#
I know the perfect answer:
-
double click on The password TextBox.
-
write your textbox name like textbox2.
-
write PasswordChar = '*';.
-
I prefer going to windows character map and find a perfect hide like ●.
example:TextBox2.PasswordChar = '●';
