Display Area

The display area of a tab control is the area in which an application displays the current page. Typically, an application creates a child window or dialog box, setting the window size and position to fit the display area. Given the window rectangle for a tab control, you can calculate the bounding rectangle of the display area by using the TCM_ADJUSTRECT message.
