I have been programming in c for about 10 years. Untill recently I used Borland c++ 3.1.  Recently I switched to DJGPP and VC.
I use VC for CGI and Server utilitys and DJGPP for just about every thing else.  I am a computer tech and ISP.  I write software to help me in my business.  My current project is customer management system, to keep track of my internet customers accounts, billings and payments. This includes generating the billings from server logs and emailing the bill to the customer.
