Datapath Wall Control - Manual (Page 41)

Microsoft PowerPoint®
To open a PowerPoint presentation as a slide show use the following command line:
/s "C:\Documents and Settings\User\My Documents\presentation.ppt"
If the presentation file name or path contains spaces, enclose the path in quotes.
For a slide show to continue cycling through the slides, the PowerPoint window must be the active window.
Only one PowerPoint application can be running at a time. If you try to start PowerPoint while it is already running, the second
PowerPoint sends a message to the first and then exits.
When a layout file is opened, Wall Control-red closes the windows and applications it is responsible for and then creates the
windows specified in the layout file. The windows and applications are sent messages to close them. The PowerPoint
application is run to create a PowerPoint window.
If the existing PowerPoint application has not finished closing by the time Wall Control-red tries to open the new presentation, it
is possible that a message to open a new PowerPoint presentation and a message to close are sent to the existing PowerPoint
application. The result is that PowerPoint closes.
