There are different question "What do you have" and "What do you continuously use"
))
My personal preference and yours may be influenced heavily by work that your are doing:
- I do have Notepad++, but use it only for HTML stuff, otherwise prefer simple Notepad
- Helidi and found it indispensable
- MS SQL Studio (and SQL server of course)
- VB 6.0 (ta-ta! absolutely indispensable!)
- VC++ (useful from time to time)
- FreeFileSync (IMHO better back-up solution that anything else)
- AstroGrep (another cannot live without utility)
Everything else pretty standard stuff.
