VBA Office : Testare se il proggetto VBA e’ protetto

With the function below you can check if a VBProject is protected before you try to edit the project:

Function ProtectedVBProject(ByVal wb As Workbook) As Boolean
' requires a reference to the Microsoft Visual Basic Extensibility library
' returns TRUE if the VB project in the active document is protected
Dim VBC As Integer
    VBC = -1
    On Error Resume Next
    VBC = wb.VBProject.VBComponents.Count
    On Error GoTo 0
    If VBC = -1 Then
        ProtectedVBProject = True
    Else
        ProtectedVBProject = False
    End If
End Function

Example:

If ProtectedVBProject(ActiveWorkbook) Then Exit Sub
