Represents a pane of a window. (There is no collection for Pane objects.) You can access the Pane object through the ActivePane, TopPane, and BottomPane properties of a Window object.
Using the Pane Object
Use a property such as the BottomPane property to return a Pane object. The following example checks for the existence of a pane at the bottom of the window and then creates, and applies, a new two-pane view.
If ActiveWindow.BottomPane Is Nothing Then
ViewEditCombination Name:="Check Resources View", Create:=True, _
TopView:="Gantt Chart", BottomView:="Resource Sheet"
ViewApplyName:="Check Resources View"
