Every file opened in Expression Web is opened as a PageWindow.

The PageWindows caption can be found with:

WebDesigner.ActiveWebWindow.PageWindows(i).Caption

Caption Output

file:///C:/Documents and Settings/rdahl/My Documents/
My Web Sites/AutomationInformation/Programming/
MicrosoftExpressionWeb/Text/PageWindows.htm	

It is often more useful to just use the nameProp property.  It can be found with:

WebDesigner.ActiveWebWindow.PageWindows(i). _ 
ActiveDocument.nameProp			

nameProp Output:

PageWindows
