Ping IP Address with VBA code and return results in Excel

Question

I have some visual basic code (see below) that tests an IP connection in column B (of an excel spreadsheet) and puts whether or not it is connected or un-reachable in column c, I was just wondering if you could help me I would like it to be green if 'connected', and any other result would be red.

Also, could this script be run automatically on an hourly or daily basis?

Many Thanks, Andy

Function GetPingResult(Host)

   Dim objPing As Object
   Dim objStatus As Object
   Dim strResult As String

   Set objPing = GetObject("winmgmts:{impersonationLevel=impersonate}"). _
       ExecQuery("Select * from Win32_PingStatus Where Address = '" & Host & "'")

   For Each objStatus In objPing
      Select Case objStatus.StatusCode
         Case 0: strResult = "Connected"
         Case 11001: strResult = "Buffer too small"

         Case 11050: strResult = "General failure"
         Case Else: strResult = "Unknown host"
      End Select
      GetPingResult = strResult
   Next

   Set objPing = Nothing

End Function

Sub GetIPStatus()

  Dim Cell As Range
  Dim ipRng As Range
  Dim Result As String
  Dim Wks As Worksheet


Set Wks = Worksheets("Sheet1")

Set ipRng = Wks.Range("B3")
Set RngEnd = Wks.Cells(Rows.Count, ipRng.Column).End(xlUp)
Set ipRng = IIf(RngEnd.Row < ipRng.Row, ipRng, Wks.Range(ipRng, RngEnd))

  For Each Cell In ipRng
    Result = GetPingResult(Cell)
    Cell.Offset(0, 1) = Result
  Next Cell

End Sub

Answer 1

You don't need code for this. Turn all the cells red, then add conditional formatting to make it green when you want.

Home > Conditional Formatting > New Rule > Use a formula...

=C2="Connected"

and format to green. If you want to do it in code, you can add some lines in your For Each loop

If Result = "Connected" Then
    Cell.Offset(0,1).Font.Color = vbGreen
Else
    Cell.Offset(0,1).Font.Color = vbRed
End If

To have this run automatically at certain intervals, check out this link.

Here's the relevant code:

Public dTime As Date
Dim lNum As Long

Sub RunOnTime()
    dTime = Now + TimeSerial(0, 0, 10) 'Change this to set your interval
    Application.OnTime dTime, "RunOnTime"

    lNum = lNum + 1
    If lNum = 3 Then
        Run "CancelOnTime" 'You could probably omit an end time, but I think the program would eventually crash
    Else
        MsgBox lNum
    End If

End Sub

Sub CancelOnTime()
    Application.OnTime dTime, "RunOnTime", , False
End Sub

I would recommend including a ThisWorkbook.Save line as I can't speak to how long this will run without crashing, and I would imagine you could see problems if you left it for days at a time.
