From one computer to another
Post by KenDown on Nov 10th, 2013, 07:50am

Is there any way in which to send a keypress from one machine on a network to another (or via BlueTooth)?

I am contemplating buying a Windows tablet and want to send the equivalent of a cursor key press from the tablet to another computer that will be linked to a projector. Thus I can stroll around with my notes displayed on the tablet but the slide to which the notes relate displayed on the projector.

Thanks.

It's not entirely clear whether you want to achieve this by writing your own program (as you've posted it on a programming forum perhaps you do) or you simply want to know whether there's an off-the-shelf solution.

In the former case you can write a program for the 'sending' PC which transmits a message using (e.g.) sockets, and another program for the 'receiving' PC which, in response to the message, fakes a keypress. Quite straightforward.

In the latter case you can download 'Synergy', which allows you to control one computer from the keyboard and mouse of another:

Thanks, Richard. I want to write my own program. I'll have to read the Wiki again and see if I can work out how to use sockets. (I'm a dab hand at repairing my car using sockets, but I suspect there are differences!)
