» Worksheet events using VBA in Microsoft Excel

VBA macro tip contributed by Erlandsen Data Consulting offering Microsoft Excel Application development, template customization, support and training solutions Events for the worksheet object occurs when a worksheet is activated or the user changes the content of a cell.
Events in worksheets are activated by default, but can be deactivated by a macro. To display the event procedures
for a worksheet you use the Visual Basic editor. Select the desired project in the Project-window and activate
the worksheet object you want by doubleclicking it. Any event procedures in the worksheet will now be displayed
in the Code-window on the right side of the screen. You can create a new event procedure by selecting Worksheet
in the Object dropdown, and then select an event in the Procedure dropdown.

Macros can be attached to the following events in a worksheet:

• Activate BeforeDoubleClick
• BeforeRightClick
• Calculate
• Change
• Deactivate
• SelectionChange

This example eventmacro will prevent the user from accessing the shortcut menus in a worksheet,
the procedure must be written in the worksheets own module sheet, e.g. Sheet1:

Private Sub Worksheet_BeforeRightClick(ByVal Target As Excel.Range, _
    Cancel As Boolean)
    Cancel = True
    MsgBox "Shortcut menus are disabled in this worksheet!"
End Sub

This example eventmacro will prevent the user from selecting cells in a specific range in a worksheet,
the procedure must be written in the worksheets own module sheet, e.g. Sheet1:

Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range)
    If Not Application.Intersect(Target, Range("A1:A100")) Is Nothing Then
        Cells(ActiveCell.Row, 2).Select
        MsgBox "You can't select cells in A1:A100!"
    End If
End Sub
