Windows Vista has "Presentation Mode", which you can turn on with the Mobility Center.
How can I turn it on programmatically?
The only way I found is to call presentationsettings.exe
with /start
or /stop
directly.
I also found this link that describes how to activate presentation mode on desktop PCs: http://www.dubuque.k12.ia.us/it/mobilitycenter/
Hope that helps.
