Programming for Touch Screens

[Michelle]

Hi, I am new it vb.net and am looking at writing for touch screens as one of
my clients wants their application written for touch screens.

I'm sure someone that done this before. Are there links I can go to to find
out what's involved, touch screen software, etc or your actual experiences
that you are willing to share, which is better than a document, I would be
most grateful.

I think it will be a fun project and would like as much information about it
before starting.

Cheers
Michelle

Just load the screen driver for the touch screen and program the Mouse Events
for the windows form to do whatever you want. You can program click, mouse
move, Mouse Down, mouse Up, etc. events. For the double click, you might
have to include a timer to distinguish between a click and double click.

michelle,

the touchscreen driver/software sets the all the mouse settings
(click,double-click,right click, etc.), so all you have to do is
install the driver / software and proceed with your code as if you're
using a mouse.

Does that mean

1) that my client doesnt have to buy actual 'touch screens' (ie: the
hardware), but instead can use software that would allow the user to still
touch a normal LCD screen and it would emulate a touch screen ; or

2) are you just saying that when developing, I can use these drivers that
come with the touch screens so that I can write events that would emulate
touching the screen?

Thanks for your quick responses.

Cheers
Michelle

michelle,

your client still needs to buy a touchscreen-enabled monitor.
touchscreens are just a means of clicking whatever controls are in the
screen directly instead of having to use the mouse.

in your development, you just have to proceed as if you are using a
mouse, but also you should be aware that external keyboard
functionality will not be available, so your program will have to
provide an on-screen keyboard (like what comes with windows xp)

Hi Diego

Thanks again for your information.

I have some more questions if you are open to them.

1. My client wants a touch screen and a keyboard (as there will be times
when information needs to be typed in). If they have a touch screen, they
can still have the functionality of the keyboard as well (or is this
functionality lost only when developing)?

2. You mention touchscreen-enabled monitor. Does that mean the monitor must
be a touch screen or any lcd monitor can be converted to one by use of
software?

Thanks again for your input

Michelle

hi michelle,

you can still have the keyboard accessible to the users of the system.

touchscreens are specially-crafted hardware devices that have two
interfaces, one goes to the regular video card interface of your cpu
and the other goes to a serial port (i haven't seen other touchscreens
not using serial ports). although there are some high-end touchscreens
that come as a package. iow, the cpu and monitor are bundled in a
single hardware. you can see these kinds of hardware mostly in fastfood
chains and restaurants.

hth,

diego

You might want to google for (touch screen wedge) before you commit.

Hi again Diego

I feel like I'm asking really silly questions, but I have to ask them in
order to understant

My client hasn't purchased touch screens yet, they want me to write the
software and in the meantime work out the hardware they want.

That being the case, can I just download a driver for a ANY touchscreen and
play around with that or each driver is specific to the brand of
touchscreen. Do you know?

If so, where would you suggest I go to get a driver for this?

Thanks again
Michelle
