MS Office Forum / General PowerPoint Questions / April 2007Using and Add-in to perform Auto_Open
How can I get an Add-in to execute code in the Auto_Open macro only for specific PPT files that I load? I've read through the examples and downloaded the code samples, but everything I see only calls subroutines and functions that are also in the add-in file. I.e., it executes every time PowerPoint starts. I'm written some code that will automatically update the footer of my slides with the filename; so that it will always show the correct filename even when someone does a SaveAs to a new name. But I don't want this same thing to happen to any other PowerPoint slides I load/save. Ideally, I'd like to do what Shyam Pillai did in his "autoevents" addin, but he didn't provide the source code that I could find. I like the idea of putting a "Auto_ShowBegin" routine in my slide presentation so that the add-in calls it if the routine exists. But, when I try to do that in my add-in, it won't compile because it can't resolve the name of the routine I want to call in my PPT file. How does Shyam make an add-in that calls a routine named "Auto_ShowBegin" when that routine exists in a different file than the add-in? Thanks for your help!

And as a working strategy, look at responding to the PresentationOpen and possibly NewPresentation events. Have the event handling routine check for some unique property of your presentation (say, the presence of a specially named or tagged shape that represents your footer) and do nothing unless that shape's found. > How can I get an Add-in to execute code in the Auto_Open macro only for > specific PPT files that I load?

There are several references online on this topic, but they all depend on all the code executing within the addin. I want to call code that's in in my PPT file like Shyam Pillai does in his AutoEvents demo. Using his AutoEvents addin, he allows me to put an event, e.g., Auto_ShowBegin, in my PPT file; not in my PPA file, and it gets called when events occur in my PPT file. How does Shyam compile a PPA file that makes calls to a PPT file when the PPT file doesn't exist at the time he compiles the PPA? If I was writing this functionality in C, I would just create a stub file so the linker could resolve the addresses, but I can't do that in PowerPoint. Any help would be greatly appreciated. > What Bill said. > [quoted text clipped - 31 lines] > PPTools: www.pptools.com > ================================================ When you wrote: "How can I get an Add-in to execute code in the Auto_Open macro only for specific PPT files that I load?" I think I misinterpreted what you're after. This in your addin would fire off Sub Auto_ShowBegin in your presentation: Application.Run "FileName.PPT!Auto_ShowBegin" Or more likely, something like: Application.Run ActivePresentation.Name & "!Auto_ShowBegin" You'd want that to be thoroughly error trapped, of course. > I read through the FAQ again, but, unless I'm misunderstanding something, it > still doesn't tell me how to do what I'm trying to do.

Thank you! The Run method is exactly what I'm looking for. That's pretty cool; it's like late binding. I can think of a lot of things I can do with that method. :-) Rather than using "ActivePresentation" I'll probably trap the Pres object from one of the standard events and use that.

Or in the case of events that pass shapes, the shape's Parent.Parent property would give you a ref to the presentation. > Thanks! > [quoted text clipped - 67 lines] > > PPTools: www.pptools.com > > ================================================ ----------------------------------------- Steve Rindsberg, PPT MVP PPT FAQ: www.pptfaq.com PPTools: www.pptools.com ================================================ I still don't get this. Where in the Add-In do I put the code: Application.Run ActivePresentation.Name & "!Auto_ShowBegin" If I put it in the Auto_Open sub in the Add-In it doesn't run correctly as there is not yet an active presentation. > When you wrote: "How can I get an Add-in to execute code in the Auto_Open macro only > for specific PPT files that I load?"

Right. You'd want the Auto_Open sub to set up event handling. You'd have the event handling routine respond to the SlideShowBegin event and run whatever code you need then. > > When you wrote: "How can I get an Add-in to execute code in the Auto_Open macro only > > for specific PPT files that I load?"
