Copying Worksheet Code Automatically

Tim correctly notes that a user can right-click on a worksheet tab, then select View Code to open a VBA code sheet for the worksheet. He has code written that automatically manipulates cells, columns, and rows. This code needs to be available on every worksheet in a workbook, even if the user adds new worksheets. Tim wonders if there is a way, using VBA, to have the code of one worksheet automatically copied to a new worksheet in the workbook.

There are a few ways you can approach this problem. One way—and perhaps the simplest way—is to remove the macros from the worksheet's code sheet and move them to the ThisWorkbook module. The worksheet's code sheet is what you see when you right-click a worksheet tab. Code in that sheet is intended to handle events that occur in the worksheet and only in that worksheet. If you move the code to the ThisWorkbook module, then events can still be handled, but those events apply to all worksheets in the workbook.

For instance, when you right-click on a worksheet tab and look at the code window, you are initially working in the Worksheet_SelectionChange event. If you wanted to move this code to the ThisWorkbook module, you could place it within the Workbook_SheetSelectionChange event.

If such a "level change" of your code won't work for some reason, then another approach is to create a template worksheet within the workbook. Give it a name such as "MyMaster," and make sure it includes all the code that you want to add to your newly created worksheets. You can even hide this worksheet, if desired, so it doesn't distract the users. Then, place the following macro into the ThisWorkbook module:

Private Sub Workbook_NewSheet(ByVal Sh As Object)
    Dim tmpName As String

    tmpName = Sh.Name
    Sheets("MyMaster").Copy Before:=Sheets(Sh.Name)
    Application.DisplayAlerts = False
    Sheets(Sh.Name).Delete
    Application.DisplayAlerts = True
    Sheets("MyMaster (2)").Name = tmpName
End Sub

This code is triggered every time a new worksheet is added to the workbook. It looks at the name of the newly added worksheet (which will be something like "Sheet4") and saves that name in a temporary variable. The code then copies the MyMaster worksheet to the workbook (which also copies the macros in the worksheet), deletes the worksheet that was originally created, and then renames the new MyMaster copy to have the same name as the original worksheet.

If the master worksheet ("MyMaster") is hidden, then the worksheet created by the macro will also be hidden. In that case, you simply need to add a single line to the macro, right before the End Sub statement:

Sheets(tmpName).Visible = xlSheetVisible
