Years ago (pre-web) I used to be a Fortran developer (yes it was a very long time ago!) but these days I run a small non-IT business. I would like to develop a database application for my clients to access via a browser (or maybe down the line via a mobile phone). I haven't done any programming for a while apart from some VB macros in Mi...

I hosted my web app on a freehoster service which shows my webpage in a frameset. 2 frames are there. In the top narrow frame there are their ad and the bottom frame is mine.

Hi there, I have a menu in a div on the side of the browser and I would like to keep it in the fixed position. However, the menu may exceed height of some screens and that would result inaccessible links. So I would like to make the menu scrollable in such a case. Unfortunately the combination position: fixed; overflow: auto; (or scroll...
I built a site for a client not too long ago and built it fairly standard. Now she has a Wordpress blog and would like an area on the main site to have links to the most recent blog posts. Is there an easy way for me to pull a list of the most recent posts into this content area without having to chop the page up into a Wordpress templ...
My focus is on html,PHP,mysql, javascript, css, ajax because that's what many websites need. I am still new to the web developing scene(only 5months) so I am busy learning all those topics. My question is whether or not to add a general purpose language, such as Python or Java, to the list. I only played a little with Python so I don't...

All the 4 systems are independent of each other but I am trying to integrate to have more automation. One of the system is as follows : I want to link my companies website (www.xyz.com) to another website (www.abc.com) with same lo...
I'm a veteran of C and very new to web design altogether. I've found myself more excited about it recently so I've been researching the technology. I'm open to using just about anything, but as I look around I see the "View" component of MVC type technologies basically being written by hand as layouts of data. I want to avoid having t...
Getting some data from a MySQL database and loading it into the page. None of the stuff really needs to be retrieved at any point other than page load, so that advantage of Ajax is moot. Is there any other advantage to Ajax? ...
Since you're using an event loop as opposed to threads, how does the actual server look? I know it uses an event loop, but how do you separate out the requests? And how do you prevent your server from running extremely slowly (since it, I assume, can only push one thing at a time since it's threadless?) Some sort of pseudo-code would b...
I'm building a Web2Py-based web application and am doing most of my development right on a remote EC2 development server.

Hi All, I've got a bit of a problem, I'm about to start a 4-6 month project which will need offline support.

I'm really interested in learning Python for web development. Can anyone point me in the right direction? I've been looking at stuff on Google, but haven't really found anything that shows proper documentation and how to get started. Any recommended frameworks? Tutorials?
