Doyce,
To put it mildly, PowerPoint is a pain in the database. It doesn't, like Word or Excel, have automatic support to execute VBA code upon opening. Sure it will execute VBA code but the code needs be created and then saved as an add-in and then added to the presentation. To top it off, if there's a desire to have the user initiate an event, the normal user buttons to be pressed need to be created dynamically upon opening the presentation and once created, the macro to be executed has to be assigned to the button. All this wonderfulness needs be placed in the aforementioned add-in.
However, there's an existing free add-in that can be downloaded from the following site: http://skp.mvps.org/autoevents.htm This add-in will provide support for auto events. The code to update a chart will still need to be written.
Then there's the fact that every object on every slide is unique so if, for example, data in a textbox needs to be updated, every object on a slide will need to be tested, once the correct slide is found, to determine if it's a text box and then if it is, a test needs be made to be certain that it's the correct text box.
It's not clear how often the chart needs be updated or by whom or if the users are geographically dispersed. It seems to me that some event in Access needs to be executed to update the data. I'd look into having that event update data in Excel and then would link an Excel graph or chart to the PowerPoint presentation. I know that it's easier to link a graph or chart in Excel to a slide in PowerPoint so that the presentation is automatically updated.
Thus endth my 02 cents,
Jeff

Subject: [MS_AccessPros] Powerpoint Graph linked to Access Query
Hello friends,
I want to link a chart in Powerpoint to Access data and have it refreshed whenever the presentation is opened. My searches for the procedures to follow have not yielded anything I can make work.Can one of you please point me in the right direction or tell me how to do this?
Doyce
