Application.Settings Property (Visio)
Returns an ApplicationSettings object, which you can use to set Microsoft Visio application properties. Read-only.
Use the Settings property of the Application object to get an ApplicationSettings object that you can then use to set various application properties corresponding to those in the Options dialog box (click the File tab, and then click Options) and the Snap & Glue dialog box (on the View tab, click the Visual Aids arrow).
This Microsoft Visual Basic for Applications (VBA) macro shows how to use the Settings property to get an ApplicationSettings object. It also shows how to use the RecentFilesListSize property to get the number of entries in the list of recently used files in Visio.
