View.Type Property
Office 2010
Returns or sets the view type.
Assembly: Microsoft.Office.Interop.Word (in Microsoft.Office.Interop.Word.dll)
WdViewType can be one of these WdViewType constants:
wdMasterView
wdOutlineView
wdPrintView
wdNormalView
wdPrintPreview
wdWebView
wdReadingView
The Type property returns wdMasterView for all documents where the current view is an outline or a master document. The current view will never return wdOutlineView unless explicitly set first in code.
To check whether the current document is an outline, use the Type property and the Subdocuments collection's Count property. If the Type property returns either wdOutlineView or wdMasterView and the Count property returns zero, the document is an outline.
