Google Static Maps API is an easy way to provide a map when the user doesn’t have Javascript available. Sure it’s not near as powerful as the full Google Maps API but still, it can provide you with a basic map that can contain both markers and paths.

After writing my first article on the subject, Ultimate Site Logo, I’ve come up with two significant enhancements.. With the original solution, there were two major flaws. The first one was a semantic one and the other one a more obvious and technical one.
This time around I think I’ve got all the details right. Well, [...]

Normally when you initialize a new Google map you set the coordinates for the center of the map and manually specifies the initial zoom level. Sometimes, however, there’s a need to dynamically calculate the center point and zoom level for certain content to fit into the viewport.

In the AJAX community, JSON have become the preferred way of sending and receiving data. That’s not surprising since it’s lightweight, fast and easy to understand. Also, since it’s a subset of Javascript, it’s familiar territory for Javascript coders.
In the ASP.NET MVC Framework, passing JSON from the server to the client script is almost too [...]

I’ve had a little trouble finding out how to use User Controls in the ASP.NET MVC Framework and how to pass data to it. I haven’t been able to find a single article that clearly explains how to do this, so I thought I’ll do a little write up on the topic.

Imagemaps was very popular in the early days of webdesign but seem to have fallen out of grace. Probably due to accessibility problems and the rise of CSS based designs. I think that it still has it’s place when used properly and one being aware of it’s potential accessibility problems.
In a recent project I was [...]

If you’re building web sites you probably mark up contact information every now and then.

Inspired by an article I’ve read on 24-ways I’ve built a demo-page for using content marked up with microformats to populate a Google Map.
Unfortunately the demo is in Swedish, but I think those of you who doesn’t speak Swedish can easily understand it anyway.
