UseSystemPasswordChar Property

MaskedTextBox.UseSystemPasswordChar Property

 

Gets or sets a value indicating whether the operating system-supplied password character should be used.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

member UseSystemPasswordChar : bool with get, set

Property Value

Type: System.Boolean

true if the system password should be used as the prompt character; otherwise, false. The default is false.

Exception Condition
InvalidOperationException

The password character specified is the same as the current prompt character, PromptChar. The two are required to be different.

The UseSystemPasswordChar property determines whether user-supplied input should be displayed in the MaskedTextBox as multiple occurrences of a password character defined by the operating system. UseSystemPasswordChar functions similarly to the PasswordChar property, but instead of using a programmer-supplied character for the prompt, UseSystemPasswordChar uses a prompt defined by the operating system. This property has precedence over PasswordChar.

System_CAPS_importantImportant

As a security consideration, the MaskedTextBox control disables cut and copy operations on password-protected strings.
