When the field's behavior is optional or mandatory, the user can modify the field by editing the contents of a text box control. If you want to display a simple text string that never changes, use a static text box control.
Text box controls give you several options related to the appearance of the typed text. You can prevent the echoing of typed characters, which is useful for entering passwords or other secure information. You can control the formatting of date and time information. You can allow the user to format the text in the control using multiple lines. You can also add scroll bars to enable automatic or manual scrolling of the field contents.
The property sheet for a text box control has four pages: General, Extended, Date/Time, and Context Menu Hooks.
The following table lists the properties of the Extended page.
