If that's what you want, evidence suggests that the way to go is a copyleft license 
like the GPL. You'd still have to decide whether you want v2, v3, v2-or-later, or 
v3-or-later, but that's outside the scope of your question.
David Wheeler has written some articles on why and how the GPL encourages sharing

If that's what you want, you need a non-copyleft license like 3-clause BSD 
which allows use in proprietary software.

If you want both at the same time, you'll need to do it manually.  That is, you 
license your software as GPL for everyone, then sell exceptions to specific parties 
who want to use your code in proprietary settings. To figure out the best way to 
go about that you'll probably want to contact a lawyer who specializes in software
