You can use the PageIndex property to specify or determine the position of a Page object within a Pages collection. The PageIndex property specifies the order in which the pages on a tab control appear.
Setting
The PageIndex property setting is an Integer value between 0 and the Pages collection Count property setting minus 1.
You can set the PageIndex property by using a Page object's property sheet, a macro, or Visual Basic.
The PageIndex property can be set in any view.
Remarks
Changing the value of the PageIndex property changes the location of a Page object in the Pages collection and visually changes the order of pages on a tab control.
You can also change the order of Page objects in the Pages collection by using the Page Order dialog box available by right-clicking the tab control in Design view and then clicking Page Order.
