I want to use my PDA touch screen as an input for my laptop via the USB port.
I'm having a bit of a mental block on getting started. Any ideas or
suggestions.

Basically, I would like to design graphical interfaces for the PDA then be
able to select them with finger taps and have it sent to a main computer.

Might be kinda silly as I would like to use it to increase the functionality
of MS Flight simulator...a good learning project.

Any design advice would be greatly appreciated.

I don't think that you want to use the PDA as an input in the conventional
sense. That's an enormous project. You'd have to make the PDA think that
it was an HID device, like a mouse, which would mean drivers, etc., etc.

Your second paragraph sounds more promising. I'm not sure what "select
them" means, but you can write a sockets-based program on the PDA to send
information about items picked from a list or display to a custom program
running on the PC which can, in turn, interpret that information and do
something (like send a mouse click or something). Note that, in this case,
you're counting on the ActiveSync interface to create a small network
consisting of your PDA and the computer and you're writing network code.

The third paragraph is back to "whoa, there!" status. You're going to have
to be more specific before I believe that you're going to somehow add flight
controls to flight simulator...

Thank you, that is some good information. I guess I should be more
clear...I wasn't actually adding controls, I would be controlling the input
for the radios and such. i know in FS2004 they have a way to assign keyboard
assignment...it sounds like that in conjuction with using sockects as you
suggest would be a good place to start.

With using ActivSync can that be a fairly fast process with little or no
delay?

Thanks again!

"Delay"? It's not going to be real-time in milliseconds, I'd expect, but
who knows.

Try salling clicker. Not sure if the windows version support it, but the
OS X version lets me use the touchscreen on my HTC Wizard as a touchpad
controlling the mouse on my mac over bluetooth or wifi.

ok...I think I got...Thank You

Can you direct me to any code samples of programming with ActiveSync?

Salling cliker is an application that you install on both device and
computer, and as far as I know, it cannot be used with a usb connection.

The Pocket PC C SDK has samples for accessing RAPI, which is the API for
ActiveSync. I don't recall the exact path, but, once you install the SDK,
look in the install directory for SDK samples.

Thank you Paul...I didn't see this reply before my last post.

Andreas...this is more of a project for learning for me. Thank you for your
suggestion.
