Making an online content editor

How would I go about making something like this in VB's DHTML Project mode?

Try looking at the source to the page, I did a quick browse and it seems most of the code is already in there...of course, it could be for something else though....

Yes, but I'm wondering... is there a way to build that in Visual Studio?
