Iím rather new to windows programming and trying to make my first program with WinApi. As a first program I chose calculator. I have done the GUI part and currently trying to make the calculation. But that is the thing, what causes me the problemsÖI just cant figure out how to do it. So my question would be, what algorithm (I donít know, id its the best word for describing that, maybe function would be better) to use for getting values from 2 fields, multiplying them (also subtraction, addition etc.) and printing the value to Static text.
