a single function with different returns

[lucromick]

hello,

How can I call individual parts of this function? I would like to call return Gallons and decPaintCostperRoom as individual entities with a single function.

Thank you for your time

 Private Function Gallons(ByRef intSquareFeet As Integer, ByRef decPaintCost As Decimal) As Decimal

        Dim decGallons As Decimal
        Dim decPaintCostPerRoom As Decimal

        'gallons is averaged by 115
        decGallons = intSquareFeet / 115
        decGallons = Math.Ceiling(decGallons)


        decPaintCostPerRoom = decPaintCost * decGallons


        Return decGallons
        Return decPaintCostPerRoom

You can only return one value. A value however can be a reference to anything you want, such as an object that encapsulates many other values. An existing framework 4+ object that might be useful to you is a Tuple. Alternatively you could define your own type using a class or structure or you could pass arguments ByRef (as you are) and alter them in the function.

I think you will want to return one of those values as the function return, and return the other in a ByRef argument.

Rather than creating your own class to return or having a ByRef parameter for the function I would advise you to split it into 2 functions. Each method should have a single responsibility.

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Const sqFt = 1000
        Dim gal = Gallons(sqFt)
        Dim cost = RoomPaintCost(gal, 19.95)
    End Sub
 
    Private Shared Function Gallons(squareFeet As Integer) As Decimal
        Return Math.Ceiling(squareFeet / 115)
    End Function
 
    Private Shared Function RoomPaintCost(gallons As Decimal, paintCost As Decimal) As Decimal
        Return gallons * paintCost
    End Function

I'm changing my answer. After looking at the code a bit closer, I totally agree with MattP: These are two functions.
