For Windows we use vb5 & Delphi & C++
Personally l hate Borland's interfaces but some of the Delphi guys swear by them or at them or something...
C++ is great for the low level stuff, personally l do the mid tier stuff so haven't touched C++ gave it away with C years ago. VB is great for writing business rules etc.
No l aint getting in to that old bug bear of my langauge is better than your langauge...they each have strengths and weaknesses. After all Universe wipes the floor with most of them for standard business apps if ya don't need windows.
