To demonstrate, let's read the password when the Logon button is clicked. To obtain the password in this form, read the SecurePassword property. This ensures that the information remains encrypted in memory, reducing the risk that it can be compromised. Ideally, you should only work with the password using a SecureString. PasswordBox provides two properties that allow you to obtain the entered password. The PasswordBox control hides the information entered, displaying symbols instead of the real characters, as shown below: The above XAML defines a basic logon dialog box that requests a user's name and password. Once loaded, replace the XAML in the main window with that shown below: Create a new WPF Application project in Visual Studio, naming the project, "PasswordBoxDemo". The extension of the file is listed in the. You will not see this option if you've selected an Offline Outlook Data File (.ost) file. On the Data Files tab, click the Outlook Data File (.pst) for which you want to change the password, and then click Settings. As we've seen these properties before, we'll only look at a few of the unique members of the PasswordBox control in this article. For Outlook 2007, On the File menu, click Data File Management. There are other similar properties too, such as MaxLength, which limits the length of the entered information. Many of the styling options provided by a standard TextBox are also available for PasswordBoxes. Additionally, the entered text is stored in a SecureString object, making it difficult to obtain the password by reading the computer's memory directly. This makes the control ideal for the entry of passwords, where the user would not want onlookers to be able to see the secret information. ![]() ![]() Instead, a symbol is added to the control for each character in the typed text. It permits the user to enter a small amount of plain text but without that text being displayed on the screen. ![]() The control will allow no more than 14 characters.The PasswordBox control looks and behaves somewhat like a single-line TextBox. The password character is an asterisk. ' The control will allow no more than 14 characters. Even though it does not appear as such, the password is still being treated as a plain-text string (unless you have implemented some additional security measure). Because the text entered is not encrypted in any way, you should treat it as you would any other confidential data. This security measure does not cover any sort of storage or transmission of the password that can occur due to your application logic. Using the PasswordChar property on a text box can help ensure that other people will not be able to determine a user's password if they observe the user entering it. The InitializeMåontrol procedure will not execute automatically it must be called. The following code example shows how to initialize a text box that will accept a string up to 14 characters long and display asterisks in place of the string. Note that you may not wish to do this as the maximum length of a password may be of use to hackers who are trying to guess the password. If the maximum length is exceeded, the system emits a beep and the text box does not accept any more characters. The property determines how many characters can be typed in the text box. Then, regardless of what character a user types in the text box, an asterisk is displayed. For example, if you want asterisks displayed in the password box, specify * for the PasswordChar property in the Properties window. The PasswordChar property specifies the character displayed in the text box. Set the PasswordChar property of the TextBox control to a specific character. ![]() A password box is a Windows Forms text box that displays placeholder characters while a user types a string.
