Full path of Map file

Question

Hi,

I am trying to get the full path of my currently open map. I can get the file name using IDocument.Title but finding the full path is a puzzle.

I tried getting the window handle and then using this to get the filename but kept getting 'Cannot Read/Write Protected Memory' errors.

Does anyone know how to get the full path of the currently open map file?

Thanks,

John

This works for Add-In reference, as long as you reference the appropriate Templates location.
ESRI.ArcGIS.Framework.ITemplates templates = ArcMap.Application.Templates;  System.Windows.Forms.MessageBox.Show(template.get_Item(template.Count - 1).ToString());
