I don't know any internet languages, just plain Delphi (and dotNET). Where should I start. Is there some usefull internet-site with examples? I also would like to know how to use a on-line database. - add items from within a web-site add dotNET program - search within items - filter items I'm pretty sure this is just basic stuff, but don't know where to start. Should I make a ASP.NET application? Just in case I didn't explain well enough. I want to create/use/update an on-line database from within a dotNET application as well as from within the internet browser. Thanks for any help.

I think IIS is better, but how do I install it? Thanks.

Best regards, Patrick Having just made one recently, the best advice I can give you is this: Think about and get a clear definition of what you want first, /then/ start writing code. I thought I had it figured out, but then the plan changed a few dozen times as my wife changed her mind on what she wanted :-) Once that is figured out, slap together some simple form layouts. This will help you catch anything you missed in your above analasys. Don't connect it to the DB or make it do anything yet, just get an outline of what users should see and be able to do. Remember that not only should they be able to select products, but they may need to select different colours/sizes etc of the items. Next build up your database tables and relations according to your requirements. After that you can make it work. Building the worker classes first and then the real front end last would be beneficial IMHO, but is not always easy. I have trouble holding myself back in this regard :-) Robins handy tips to remember in web sites: 1) Think about what users should be able to see and what they should not. For instance, the cart can be kept in the session (invisible) because it is used by your web site not the user. However passing the product ID in the URL is cool because then a link to a certain item can be emailed, book marked etc. 2) ALWAYS use parameters in DB Queries. Otherwise you open yourself up to SQL injection which can be disasterous. 3) CSS and UserControls (in asp.net) allow you to write code once, use it everywhere. In design the saving can be minimal to good, but when you are making changes after creation, you will kick yourself if you don't! 4) Delphi makes it really easy to slap together a quick-n-dirty app to manage your database. Nothing pretty, just enough to enter test data. Don't be afraid to take advantage of this in the short term and come back later and write a real management tool. Good luck! -- Robin.
