VBA Office : Cancellare una procedura a run time

With the macro below you can delete an existing procedure from a module:

Sub DeleteProcedureCode(ByVal wb As Workbook, _
ByVal DeleteFromModuleName As String, ByVal ProcedureName As String)
' requires a reference to the Microsoft Visual Basic Extensibility library
' deletes ProcedureName from DeleteFromModuleName in wb
Dim VBCM As CodeModule, ProcStartLine As Long, ProcLineCount As Long
On Error Resume Next
Set VBCM = wb.VBProject.VBComponents(DeleteFromModuleName).CodeModule
If Not VBCM Is Nothing Then
' determine if the procedure exist in the codemodule
ProcStartLine = 0
ProcStartLine = VBCM.ProcStartLine(ProcedureName, vbext_pk_Proc)
If ProcStartLine > 0 Then ' prosedyren finnes, slett den
ProcLineCount = VBCM.ProcCountLines(ProcedureName, vbext_pk_Proc)
VBCM.DeleteLines ProcStartLine, ProcLineCount
End If
Set VBCM = Nothing
End If
On Error GoTo 0
End Sub

Example:

DeleteProcedureCode Workbooks("WorkBookName.xls"), _
"Module1", "ProcedureName"
