A boolean value indicating whether to put the RichTextEdit into preview or edit mode. Values are:

Integer. Returns 1 if it succeeds and -1 if an error occurs.
A RichTextEdit control has two ways of viewing the content: edit mode and preview mode. The Preview function switches between the two.
Edit mode displays the text in readable form. The user can enter, select, and change text. There are properties for controlling the display of nonprinting characters in the text, such as carriage returns, spaces, tabs, and input fields. In edit mode, the toolbar, ruler bar, and tab bar, if visible, display above the editing area of the control.
Preview mode displays a miniature page within the control. The page is sized to fit within the control. Any selection is canceled when the control switches to preview mode. The user cannot edit text in preview mode, but scripts can call functions for selecting and changing text, including inserting documents. Users can page through the control contents in preview mode by using the up arrow and down arrow keys, or the Page Up and Page Down keys.
If you call ShowHeadFoot when the control is in preview mode, you return to edit mode with the header and footer editing panels displayed.
Make sure the RichTextEdit control is big enough to display the page formatting and scrolling controls available in preview mode.
This example previews the page layout of the RichTextEdit rte_1:
rte_1.Preview(TRUE)
