Nothing other than VS.NET or VS6 for doing Visual Basic. If I'm feeling lucky and I can do without Intellisense, then generally working in vim or in a gray text on black background window is easier on the eyes for C. I guess I could change VS to those colors too but the feel is just not the same. 😉
For HTML, I made my own editor in VB6. It's just a comfortable environment with an interface to an XHTML tidy DLL I wrote in C, and a log window at the bottom for errors and warnings from the tidy DLL. And if by development environment you mean a can of Sprite, some Doritos, and an easy-on-the-eyes LCD screen (all paired with taking breaks every 30 mins to vent off my anger from debugging), that suits my preferences well. 😉
