MS Office Forum / General PowerPoint Questions / August 2006override the saveas function in powerpoint
Hei. I'm programming an addin using c#. My applications overrides the users actions to save a presentation. I add some information and needs to save the presentation myself. In word and excel there is a method called document/workbook saveas. I cant get the method for saving a presentation to work... theActivePpt.SaveAs(filename, Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPresentation, Microsoft.Office.Core.MsoTriState.msoTriStateMixed); I have tried serveral versions of the variables above. I really hope someone knows how this can be solved :) > Hei. > [quoted text clipped - 12 lines] > > I really hope someone knows how this can be solved :) First we need to know what "this" is. You say you can't get it to work but what does that mean? You get error messages? Crashes? Smoke out of the back of the computer? :-) But for starters, have you just tried theActivePpt.Save ----------------------------------------- Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ I get an exception when the saveAs method written earlier is called: - the exception is a system.runtime.interopServices.COMException - the error code is: -2147467259 - the message is Presentation(unknown member): Failed. I tried your suggestion (theActivePpt.Save) - then I got an exception as well :( Neoret > > Hei. > > [quoted text clipped - 24 lines] > PPTools: www.pptools.com > ================================================ > I get an exception when the saveAs method written earlier is called: > - the exception is a system.runtime.interopServices.COMException [quoted text clipped - 3 lines] > I tried your suggestion (theActivePpt.Save) - then I got an exception as > well :( FWIW, this in VBA works fine: Sub TestSave() ActivePresentation.SaveAs ("q:\support\junk.ppt") End Sub and would work equally well as: oPresentationObject.SaveAs .... Could it be that theActivePpt holds a reference to something other than a Presentation object? > Neoret > [quoted text clipped - 26 lines] > > PPTools: www.pptools.com > > ================================================ ----------------------------------------- Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ Thanks for helping me getting closer to success! Could this have anything to do with late bounding? I found out in debugging that when I run this method from word the applicationobject = Microsoft.office.interop.word.applicationClass. When I run it in powerpoint the applicationobject = System_Comobject... This is probably the problem - but do you know why this happens? > > I get an exception when the saveAs method written earlier is called: > > - the exception is a system.runtime.interopServices.COMException [quoted text clipped - 53 lines] > PPTools: www.pptools.com > ================================================ > Thanks for helping me getting closer to success! > > Could this have anything to do with late bounding? It could, I suspect. Since I don't use C# or .Net I can't easily interpret the results you're seeing, but if you were doing the same thing in VB/VBA you'd need to declare the presentation object as a generic object rather than as a presentation. > I found out in debugging that when I run this method from word the > applicationobject = Microsoft.office.interop.word.applicationClass.
