MS Office Forum / General PowerPoint Questions / June 2006Enable/Disable Add-in
Hi All I've created an add-in for ppt 2002 I'd like to enable / disable it depending on whether a presentation is open or not. Is there an easy way to do this? Thanks Trevor > Hi All > > I've created an add-in for ppt 2002 > > I'd like to enable / disable it depending on whether a presentation is open > or not. Is there an easy way to do this? Simplest is to have your code do something like: If Windows.Count = 0 Then ' No presentations ' Optionally ... MsgBox ("Open a presentation then try again, please.") Exit Sub End if ' remainder of your code follows ... ----------------------------------------- Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ Thanks Steve - that'll do it. Out of curiosity, do you know if the menu item for the Add-in can be grayed out (therefoere not useable) until a presentation is open?

If you implement an event handler, it should be, yes. Make PPT respond to events http://www.rdpslides.com/pptfaq/FAQ00004.htm Off top of head, you'd want to trap the PresentationClose event and disable the menu if there are no presentations active; and trap the New Presentation and PresentationOpen events to enable the menu. It might be enough just to work with the WindowActivate event; enable the menu if there's a presentation active and disable it if not. > Thanks again > [quoted text clipped - 23 lines] > > PPTools: www.pptools.com > > ================================================ ----------------------------------------- Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ Splendid, I'll give it a go.
