excel vba - How to create a range from 2 ranges in VBA

I have two ranges each containig a single cell (for example "A1" and "C3")

What is the easiest way to get a new range containing all the cells between these two ("A1:C3").

I am trying to write something like this, but this doesn't work:

 Set NewRange = Range(Range1.Address:Range2.Address)

Another question I have is how to set a range in R1C1 format? I want to use something like Range("R1C2") instead of Range("A2").

Thanks!

Answer

Like this?

Sub Sample()
    Dim rng1 As Range, rng2 As Range

    Dim NewRng As Range

    With ThisWorkbook.Sheets("Sheet1")
        Set rng1 = .Range("A1")
        Set rng2 = .Range("C3")

        Set NewRng = .Range(rng1.Address & ":" & rng2.Address)

        Debug.Print NewRng.Address
    End With

End Sub

Instead of R1C1 format use Cells(r,c). That will give you more flexibility + control

So Range("A2") can be written as Cells(2,1)
