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

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 ...
 
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?

Thanks again

If you implement an event handler, it should be, yes.

Make PPT respond to events

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.
 
Splendid, I'll give it a go.

Thanks again
