just fyi application running in vs-2010 wpf.

so please me out if have faced issue earlier or if have solution or alternative this.

don't recall exact details off top of head, think 1 of options on open dialog read only.

marking active presentation .saved = true real answer problem, here vb.net sample using dynamic binding (not interop assemblies):

pp = powerpoint application object  dim ppa object = pp.activepresentation ppa.saved = true
