Excel VBA copy or reference a value

Excel VBA provide options on how to pass value from worksheet to worksheet or from workbook to another workbook.
To optimize or make the VBA code run faster is to make the worksheet interaction lesser.
Recording an Excel VBA macro to copy and paste a value will have a similar output to the code below.
Sub Macro1() ' ' Macro1 Macro '     Range("A2").Select     Selection.Copy
    Sheets("Sheet2").Select     Range("A3").Select     ActiveSheet.Paste
End Sub

Excel find last row with value in a specific column

1. How to find last row with value using vba in a specific column?

2. How to find last row with value  using vba in a worksheet?

The questions above are entirely two different scenarios.

The first question will find the last row with value in a specific column within the worksheet.

While the second question find the last row with value of the entire worksheet.

The first question is applicable if you need to find the last row in different columns.

Let's say Column 1 or Column A, or Column 2 or Column B etc.

Example code below will find the last row in a specific column via VBA code.

'command Cells(Rows.Count, 1) = find the last row with value in Column 1 for Sheet3

Dim last_row As Integer

last_row = Worksheets("sheet3").Cells(Rows.Count, 1).End(xlUp).Row

Msgbox last_row

'replace 1 with the desired column 
'ex: command Cells(Rows.Count, 7) = find the last row with value in Column 7

Cisco block telnet and SSH access

Block telnet and SSH access to the Cisco router.

The user must have the privilege to change the settings or basically the admin user account.

Block all (telnet and ssh):

  line vty 0 4
  transport input none

sh startup-config (save config and will persist after reboot or shutdown)

sh running-config (config is save but will not persist after reboot or shutdown)

To enable or unblock:

line vty 0 4
 privilege level 15
 login local
 line vty 0 4
transport input telnet ssh

Before rolling out to production be sure to test it out or else you will leave a vulnerability in your network.

Cheers..till next time!
