Description

Creates a new MapDocument with the specified filename on your system. Any MapDocument that is currently open will be closed. The new document is created and opened with a PageLayout containing one empty Map with the version information and DocumentFilename property set.

Remarks

When opening or creating a map document with the IMapDocument Open() or New() methods, you should always make subsequent calls to IActiveView::Activate() in order to properly initialize the display of the PageLayout and Map objects.  Call Activate() once for the PageLayout and once for each Map you will be working with.  If your application has a user interface, you should call Activate() with the hWnd of the application's client area.  If your application runs in the background and has no windows, you can always get a valid hWnd from the GDI GetDesktopWindow() function, part of the Win32 API.
