How to set a text box for inputing password in winforms?

Question

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

<input type="password" /> in HTML.

Answer 1

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.

Answer 2

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.");   }
