Function v Get Property

[tiredofit]

What's the difference between a function and the Get Property?

Both TestFunction and TestProperty generate the same results.

Option Explicit

Sub TestFunction()

    Dim d As Long
    
    d = MyFunction(1, 2, 3)

End Sub


Sub TestProperty()

    Dim d As Long
    
    d = MyProperty(1, 2, 3)

End Sub

Function MyFunction(a, b, c) As Long

    MyFunction = a + b + c

End Function


Property Get MyProperty(a, b, c) As Long

    MyProperty = a + b + c
    
End Property

Thanks

As long as you don't need to pass any arguments ByRef, nothing really. It's a little unusual to have a property that requires any arguments, and certainly not 3.

Thanks.

(And if you do have to pass args, then the difference is that Properties always pass ByVal, (as you said in my other post), whereas Functions can be either)?

The main difference isn't in the Property Get, but the Property Let/Set.

If you are going to be setting the value as well as fetching it, Property Get / Property Set is the best way to go. Although you could use a function and a sub instead.

That's correct.
