Need help to get started with a Touch Screen Application

Hi All
I want to write a touch screen POS application. I am trying to get this
accomplished in c#.net. I have very good experience in developing stand
alone applications and web applications using both c#.net and vb.net. I
am trying to get my foot into this touch screen applications. I have
never developed one before. Is there any reading material or an online
form that any one can suggest.
Thanks for your help

the ones that we have played with required no additional programming
because they integrated seemlessly with windows. touches were treated
as mouse events.

so, the only real difference on the design side will likely be the
usage of more buttons than normal on your form... one other potential
difference may be the need to create an on-screen keyboard...

every good designed program can be run on a touchscreen monitor ,,, it is
not necessary to write extra code however it should be taken care of in the
design of the app ( buttons big enough to touch with a pointing finger

I have done this for my restaurant management program and it requires no
extra programming since the mouse events "Click" and "DoubleClidk" are
triggered by the touch screen. Also, you can implement Drag and Drop thru
the mouse down, move events and mouse up. However, some events such as mouse
move won't trigger unless the screen is pressed. Also, the mousehover event
won't work.

The main problem that I had was that the buttons have to be quite large
since the perspective of the user depends a lot on the height of the screen.
Also, you need to allow a button for the user to calibrate the touch screen
since it needs calibration almost weekly.
