```vba

Private Sub Workbook_Open()

Dim userName As String

UserName = Application.UserName

MsgBox "Welcome, " & userName & "! Let's get started.", vbInformation

' Set up user-specific settings

Sheets("Settings").Range("A1").Value = userName

' ... additional code to set up the environment

' Error handling

On Error GoTo ErrorHandler

' ... code that might produce an error

Exit Sub

ErrorHandler:

MsgBox "An error occurred: " & Err.Description, vbCritical

' Handle the error

End Sub

In this code, when the workbook is opened, it greets the user with a message box and then sets a cell value to the user's name. It also includes basic error handling to manage any potential errors that might occur during the execution of the event.

By harnessing the power of the `Workbook_Open` event, developers can ensure that their Excel applications are not only powerful and efficient but also user-friendly and secure.

6. Automated Corrections: The event can also be programmed to automatically correct common data entry errors, such as formatting phone numbers or capitalizing names.

Let's consider an example to highlight the idea:

```vba

Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)

If Not Intersect(Target, Sh.Range("A1:A10")) Is Nothing Then

' Check if the changed cell is within the range A1:A10

If IsNumeric(Target.Value) And Target.Value > 0 Then

' If the value is a positive number, format it as currency

Target.NumberFormat = "$#,##0.00"

Else

' If the value is not a positive number, clear the cell and alert the user

Target.ClearContents

MsgBox "Please enter a positive number.", vbExclamation, "Invalid Entry"

End If

End If

End Sub

In this example, the `Workbook_SheetChange` event is set up to monitor the range A1:A10. If a user enters a value in this range, the code checks if it's a positive number. If it is, the cell is formatted as currency. If not, the cell is cleared, and the user is alerted to enter a positive number.

By harnessing the power of `Workbook_SheetChange`, you can create robust, self-validating spreadsheets that significantly reduce the risk of data corruption and human error, ensuring that your data remains pristine and reliable.

5. Tracking Changes with Workbook_SheetSelectionChange
