Default sorting numbers

i have a simple sheet that basically consists of

name, ip address, and then other columns

obviously when i sort by ip address the .1,.2,.3,.4,.5, etc get sorted
in between the higher numbers ie:

99
100
1
101
102

and i have to manually move them

i cant seem to see how you can sort within a column

if the above makes sense :)


Try this VBA Sub.

To use it, select either one cell in the table, in which case the entire table
will be sorted; or select the area you wish to sort, in which case just the
selected cells will be sorted. The <alt-F8 opens the macro dialog box.
Select SortIP and RUN.

At least one column must be IP addresses in the usual form.

The Sub tests for a column header -- none of the headers can "look like" an IP
address.

To enter the Sub, <alt-F11 opens the VB Editor. Ensure your project is
highlighted in the project explorer window, then Insert/Module and paste the
code below into the window that opens.

======================================
Option Explicit
Sub sortIP() 'sorts IP addresses
Dim i As Long, j As Long, k As Long
Dim IP
Dim rg()
Dim RangeToSort As Range
Dim IPaddress As String
Dim IPColumn As Long

IPaddress = "#*.#*.#*.#*"

Set RangeToSort = Selection

'If just one cell selected, then expand to current region
If RangeToSort.Count = 1 Then
Set RangeToSort = RangeToSort.CurrentRegion
End If

'Check if row 1 contains an IP address. If not, it is a header row

'first find column with IP addresses. Check row 2 since row 1 might be header
IPColumn = 1
Do Until RangeToSort.Cells(2, IPColumn).Text Like IPaddress
IPColumn = IPColumn + 1
If IPColumn RangeToSort.Columns.Count Then
MsgBox ("No valid IP address found in Row 1 or Row 2")
Exit Sub
End If
Loop

If Not RangeToSort(1, IPColumn).Text Like IPaddress Then
Set RangeToSort = RangeToSort.Offset(1, 0). _
Resize(RangeToSort.Rows.Count - 1, RangeToSort.Columns.Count)
End If



'one extra column for the IP sort order
ReDim rg(RangeToSort.Rows.Count - 1, RangeToSort.Columns.Count)



For i = 0 To UBound(rg)
For k = 1 To UBound(rg, 2)
rg(i, k) = RangeToSort.Cells(i + 1, k).Text
Next k
IP = Split(rg(i, IPColumn), ".")
For j = 0 To 3
rg(i, 0) = rg(i, 0) & Right("000" & IP(j), 3)
Next j

Next i

rg = BubbleSort(rg, 0)

For i = 0 To UBound(rg)
For k = 1 To UBound(rg, 2)
RangeToSort.Cells(i + 1, k) = rg(i, k)
Next k
Next i

End Sub

Function BubbleSort(TempArray As Variant, d As Long) 'D is dimension to sort on
Dim Temp() As Variant
Dim i As Integer, j As Integer, k As Integer
Dim NoExchanges As Boolean

k = UBound(TempArray, 2)
ReDim Temp(0, k)

Do
NoExchanges = True

For i = 0 To UBound(TempArray) - 1
If TempArray(i, d) TempArray(i + 1, d) Then
NoExchanges = False
For j = 0 To k
Temp(0, j) = TempArray(i, j)
TempArray(i, j) = TempArray(i + 1, j)
TempArray(i + 1, j) = Temp(0, j)
Next j
End If
Next i
Loop While Not NoExchanges

BubbleSort = TempArray

End Function
