Excel VBA: How to Extend a Range Given a Current Selection - excel

Question

I want to do something like:
E18-(1,1) &":" &E18+(1,1)
My intent is to keep the selection of range E18 (value = B) and extend the selection to D16:F20.
If I have a cell's range of E18 and I want to extend the range to D16:F20, how can I do this?

Answer 1

You mean like this?
SYNTAX
ExpandRange [Range], [Number of Col on left], [Number of Rows on Top], [Number of Col on right], [Number of Rows down]
Sub Sample()
Debug.Print ExpandRange(Range("B5"), 1, 1, 1, 1) '<~~ $A$4:$C$6
Debug.Print ExpandRange(Range("A1"), 1, 1, 1, 1) '<~~ Error
Debug.Print ExpandRange(Range("XFD4"), 1, 1, 1, 1) '<~~ Error
Debug.Print ExpandRange(Range("XFD1048576"), 1, 1, 1, 1) '<~~ Error
Debug.Print ExpandRange(Range("E5"), 1, 1, 1, 1) '<~~ $D$4:$F$6
End Sub
Function ExpandRange(rng As Range, lft As Long, tp As Long, _
rt As Long, dwn As Long) As String
If rng.Column - lft < 1 Or _
rng.Row - tp < 1 Or _
rng.Column + rt > ActiveSheet.Columns.Count Or _
rng.Row + dwn > ActiveSheet.Rows.Count Then
ExpandRange = "Error"
Exit Function
End If
ExpandRange = Range(rng.Offset(-1 * tp, -1 * lft).Address & ":" & _
rng.Offset(dwn, rt).Address).Address
End Function

Answer 2

Here is the simple code that I use to resize an existing selection.
Selection.Resize(Selection.Rows.Count + 5, Selection.Columns.Count + 50).Select
This will add 5 to the row count and 50 to the column count. Adapt to suit your needs.

Answer 3

You can use Application.WorksheetFunction.Offset() which is richer than VBA's Offset and does everything required by the question.
I think it does what Siddharth Rout ExpandRange does, without the need of a UDF.

Answer 4

Range(Cells(WorksheetFunction.Max(1, Selection.Row - 1), _
WorksheetFunction.Max(1, Selection.Column - 1)), _
Cells(WorksheetFunction.Min(Selection.Worksheet.Rows.Count, _
Selection.Row + 1), _
WorksheetFunction.Min(Selection.Worksheet.Columns.Count, _
Selection.Column + 1))).Select

How to select and extend a range from anywhere on a sheet, to anywhere on a sheet.
This is my first post. I know I'm a little bit late to the party, and it's obvious to me that most of the people here are far far more experienced and skilled than I am. So I doubt my solutions include much of their "big picture" nuanced considerations, but I've verified they work for me and I hope they work for all of you too.
Okay, so back to the question.
Here is how I do it.
Example One
To do this for the exact scenario posed by your question, if you’re starting at E18 and you want to extend the range to D16:F20, use the code below. As long as you have room for the full range, your active cell can actually be anywhere, and that range will follow it.
Range(ActiveCell.Offset(-2, -1), ActiveCell.Offset(2, 1)).Select
Example Two
If you’ve already selected a range, and then you want to expand it further (let’s say and additional 2 rows down and 1 column to the right), then do this:
Range(Selection, Selection.Offset(2, 1)).Select
Example Three
If you want to select a range of all the contiguous cells containing data, starting from the active cell and continuing down until it reaches a blank cell, and then also add the cells from 1 column to the left, then do this:
Range(ActiveCell, Selection.End(xlDown).Offset(0, -1)).Select

Answer 6

Instead of returning an absolute address, I modifying the syntax above to return a range. Credit goes to Siddharth Rout = )
Function ExpandRG(rng As Variant, lft As Long, tp As Long, rt As Long, dwn As Long) _
As Range
Set ws = rng.Parent
If rng.Column - lft < 1 Or _
rng.Row - tp < 1 Or _
rng.Column + rt > ActiveSheet.Columns.Count Or _
rng.Row + dwn > ActiveSheet.Rows.Count Then
MsgBox "Out of range"
Exit Function
End If
Set rng = ws.Range(rng.Offset(-1 * tp, -1 * lft).Address & ":" & _
rng.Offset(dwn, rt).Address)
End Function
Sub aa()
Dim ori_add, O_add, New_add As Range
Set ori_add = Range("B2")
Set O_add = ori_add
Call ExpandRG(ori_add, 1, 1, 1, 1)
Set New_add = ori_add
MsgBox "Original address " & O_add.Address & ", new address is" & New_add.Address
End Sub
