I am using powerpoint interop API to open a slideshow from a new instance

  • 0

I am using powerpoint interop API to open a slideshow from a new instance of PowerPoint (in this case, PowerPoint 2007).

In my app, I need to avoid the mouse changing the slide or showing up the right-click menu, so I manually configured that in PowerPoint.

What I did:

1.- For left click I went to “Animations”>”Advance slide” and unchecked “On mouse click”.

2.- For right click I went to “PowerPoint Options”>”Advanced”>”SlideShow” and unchecked “Show menu on right mouse click”.

I would like to know how to do steps “1” and “2” programatically using the API, since I want my app to work in the same conditions in other computers.

Thank you in advance.

    For number 1, you are looking for the SlideShowTransistion interface and in particular the AdvanceOnClick property. It looks like you need to set it for each slide in the presentation:

    pptSlide.SlideShowTransition.AdvanceOnClick = Microsoft.Office.Core.MsoTriState.msoFalse;

    For number 2, I can’t find anywhere this is exposed through the interop API. The only method I can find to disable it is to modify the registry key (this would be per user install).

    On my Powerpoint 2003 install it is controlled by the 

    HKEY_USERS\Unique-ID-For-User\Software\Microsoft\Office\11.0\PowerPoint\Options\SSRightMouse

    reg key.
