I would recommend you to take time to grasp programming fundamentals first, not hustle to get into business quickly if you want it that way. And yes, programming skills are not required for business.

For visual basic 6 (since you have Visual C++ 6.0, I would imagine you have Visual Studio, alongwith Visual Basic 6.0 too...unless you bought VC++ separately), "Mastering Visual Basic 6" is a good book. Combine that with msdn and you get a good learning recipe.
