Im making an kind of "calculator" application in VB (6.0) which has two two inputs and 4 outputs - each with corrosponding comboboxes illustrating the kind of data in each (eg, kj/kg, m3/kg etc) creating different outputs through different formula. You enter numerical values into the input text feilds and depending what index is selected in the corrosponding comboboxes, different formula are used in producing the outputs in the output fields (labels). And its the same with the outputs, they have corresponding comboboxes illustrating the kind of data. I guess basically what im saying is, how do i incorporate comboboxes into altering the formula used in the inputs and then displaying different data in the output?
Iv got the feeling that the dribble iv just written could be hard to make sense of but if anyone knows what im talking about then any help would be appreciated. I got the VB manuals etc so just maybe a jist of what to look up etc. The formulae come from a psychrometric chart just incase anyones familiar thermodynamic properties... :S
