Hi all. I'm looking to handle image uploads on a site I'm building. All the behind the scenes stuff is fine, but creating an intuitive front-end is causing me head pains. The problem with handling photos in a world where most people have asynchronous internet connections is the photos' size. I want each user to upload (at least) 10-20 i...

My website has an Atom feed and I want to make it easier to subscribe to it. I see that many sites such as StackOverflow have the Atom icon in the location bar in Firefox 3. I haven't, however, been able to work out how. I assume some HTML is needed - but what tags specify the the browser that a page has a feed? ...

I have a number of generated html tables that I need to output as an Excel file. The site is codded in classic ASP. Is this possible? Could it be done by somehow using the Open Office libraries?

Is there any way to generate PDF files from classic ASP? I have a bunch of user-entered data that needs to be turned into a PDF that the user can download. How can I do this? OpenOffice allows exporting documents to PDF, so could this somehow be leveraged? ...
My question seems easy but is little more theoretical than it looks. There are Code Generation software or application building software that gets done without the use of a programming language. Application like VE Server and VE Designer from Intelliun should accomplish this task. My question is, in reality have someone out there trac...
I would like users to be able to double click anywhere on the screen to display a form that allows submission of feedback about that very spot. I can think of 2 solutions: Store X,Y coordinates. Had to rule this out since X,Y coordinates aren't supported on all browsers. Use Jquery to bind an exhaustive list of html entities to a dbl...

If I were to implement a web application from scratch today, which app stack should I go for? Three main candidates are java, python and Ruby on Rails (RoR). There is also .NET, but its biased towards M$. Pro-java: 1) Stacks of thick books 2) Largest developer community 3) Typed languages, which prevents subtle bugs 4) Augmented with ...
The expected behaviour on enter in a form seems to be undefined in the HTML 4.01 Specification while the HTML 5 specification says it should be the first submit button in the form. Internet Explorer (IE) highlights the first button in the form when the form has focus by adding a proprietary border or something. Other browsers do not ad...
I have made a little app for signing up for an event. User input their data and click "sign me in". Now sometimes people are double in the database, the exact same data that got inserted 2 times very quickly after each other. This can only mean someone clicked the button twice, which caused two posts to happen. This is common web pro...

I can understand the basics about creating the repository and checking out etc but need help for the web server. I'm running apache and subverion is running on the development server I'm working on. Now do I creat...
A (non-technical) friend of mine has asked me how to make a website. I get this question all the time. After a few questions I found out that she has an idea that could turn into a commercial site. I described three options to her: a) Get a book/enroll in a class/follow some online tutorials and learn how to do it. She's pretty smart an...
Looking at implementing caching for some common lookup data in an asp.net web application. In the past, I've created a singleton that creates a bunch of hashtables, which have public accessors. This works pretty well for read-only data that never changes. I've done a bit of looking into the System.Web.Caching, but it doesn't seem to o...
Our Dev team had been developing enterprise web page more than 2 years ago. We are curious to know what is the best way to write a contract for CSS usage. For example, if we have a COMP, how we agree on a contract so our developers and our designers agree and we don't have to go back. Is there a tool that is available for this type ...

Let's say I have a simple ASP.NET MVC blog application and I want to allow readers to add comments to a blog post. If I want to prevent any type of XSS shenanigans, I could HTML encode all comments so that they become harmless when rendered. However, what if I wanted to some basic functionality like hyperlinks, bolding, italics, etc? ...

I have a Linux web server and I'd like to make some database tables (currently in Access) available on the web for CRUD. There needs to role-based security. What's the quickest path to develop this?
