However, it would be best to have it using a touch sensitive screen and do away with a mouse and keyboard - a 'kiosk' idea. In principal, a touch sensitive screen simply acts as a mouse click, so there shouldn't be any major problems, but there are a couple of issues that I need to address: 1) Assume that I have a field which is designed to accept a name. Somewhere on my web page will be a representation of a keyboard for users to press. So the first problem is how do I fill the name field as a user 'clicks' a letter? As a Delphi programmer this is trivial, but on a web page it is not. 2) The second issue is having room on my web page for a keyboard, which I don't. The answer might be to have a pop-up window with my keyboard on it, but then there is another problem - you cannot have modal web windows, so it is easy to loose the pop-up behind the maximised web browser. Well, I think you can, but I don't know how to. I guess this highlights the fact that I am a Delphi programmer, not a web designer. It occurs to me that this might have nothing to do with Delphi CGI at all and is just a web design/JavaScript problem, but if anyone has done anything like this, you might have some thoughts on how I should best approach it. Thanks.

Usually, it's the same app, but a parameter changes the behaviour to touchscreen. The first thing that is apparent for the kiosk mode, is that there is no keyboard present. So, why would the user need to have a keyboard? This is simply a design question for you, and the basic principal is to assume that the kiosk user isn't going to keyboard enter. Of course it's possible to simulate modal windows in a web browser, but is this the right way in the first place?

Thanks for the thoughts Ray. However, take a simple example of where a user must enter a name and password to gain access to the system. You must be able to touch letters on the screen to do this, so however you design the system to not need keyboard type entry, there are always going to be some aspects of it that need this functionality. I think you are right, though, when you imply that if you design it well, you can minimise the necessity for mimicking keystrokes. Tim.

I was thinking more along the lines of what kind of system is it that requires protected access from a (presumably) public location. Traditionally, a touchscreen/kiosk system doesn't require username/password etc, as they are generally public access systems (in my experience) Ray "Tim" <tim (AT) evolvedatasystems (DOT) co.uk> wrote in message news:44868988 (AT) newsgroups (DOT) borland.com...

Hi Tim, I've done a kiosk for our golf club and users can enter their club id to enter competitions etc. The below is the windows shortcut placed in the startup directory of the pc that is the kiosk. "C:\Program Files\Internet Explorer\IEXPLORE.EXE" -k http:\\www.goesegolfclub.nl\StyleSheets\Kiosk_On.html The -k puts IE in kiosk mode, which does away with menu and toolbars. The url points to a special version of the standard club site. This adds a numerical keyboard and scroll buttons to the page. The buttons are html <a> tags, with javascript attached to the onclick events. The javascript populates an html input box with the clicked number. As this is all client side scripting, you should be able to lift the code and find out how it works. Good luck, Hans van Leth.

As it happens, this is for a court booking system for a sports club, so we need logins etc. for individual members, which then takes money off their accounts each time they book facilities. Hans, I like your golf club. Nice web site and I see how you have used JavaScript. I might pop over for a game one day! Thanks again.
