You are looking for a Lookup with multiple criteria. A quick search gives several useful links, listed below. I have marked with * those that I have answered.
I have filtered out some of the links that actually deal with other issues.
As seen in the links, there are several options to achieve your goal. I personally prefer those that do not need array formulas, using an answer to question 1 with LOOKUP or an answer to question 2 with SUMPRODUCT.
Since you mentioned that you need a VBA solution, you can use WorksheetFunction to use an Excel formula in VBA code, or check answers to question 7.
