I Used only one button in Tpdesign. I want to use that button for triggering both ON & OFF the Projector .

what is the Syntax for it?

Evaluate the state of the projector power and call on or off as required.
If you have implemented a SNAPI compliant module then just toggle channel 255 (POWER_ON) at the virtual device

[vdvPROJECTOR, POWER_ON] = ![vdvPROJECTOR, POWER_ON];

That depends on the control method. IP? RS-232? IR?
