Hmmm. I always thought, there would come a kind of mouse driver with such a touch screen hardware, so you wouldn't have to write anything yourself...
Am I wrong with that?

Madshi, I have know idea..  I have never did any programming that involved touch screen, that is why my question may seem a little unclear. I just want to know how you go about doing it?  Do you code your program and then get some hardware that allows for touch screen i.e. touch screen monitor?  I know that you will need some type of hardware, but where can I get the information on this advanced level of programming?

I think Madshi is right.  I dont think there would be any need at the program level to treat a touch screen system any different than a mouse driven system.  I have worked with only one system (it was for a nightclub POS), and it was a simple mouse driver replacement.  The one thing I can recommend is to make buttons much bigger than usual if you intend to use your program with a touch screen.  This makes things much easier for the user.

Hi all,

I guess you have to detect somehow which button a user has touched, a while back there was a similar question here or in one of the newsgroups, and I came across an interesting site have to look it up (where???? :O)). They used a layer for the screen to detect the area touched.

I'll be back on this one.....

Hi,

Why don't you refere to the TOUCH SCREEN Manual as there must be an example written in one of the following languages (BASIC or C), and for sure also that you will find a demo codes in their site, example: if the touch screen company called MAGICTOUCH then try www.MAGICTOUCH.COM, I hope this will work for you, thnx.
