Assembly: System.Windows.Forms (in system.windows.forms.dll)

public bool UseSystemPasswordChar { get; set; }
/** @property */
public boolean get_UseSystemPasswordChar ()

/** @property */
public void set_UseSystemPasswordChar (boolean value)

public function get UseSystemPasswordChar () : boolean

public function set UseSystemPasswordChar (value : boolean)

Not applicable.

Property Value

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

Exception typeCondition

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.

NoteImportant:

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