[MS_AccessPros] Error Handling MS Template

 

For my education, I am trying to convert some MS templates from macros to code.  Can someone explain why the various MS template subs have two different error handling statements, one after the other, as below?  What error would the first error statement handle?  I assume the first error statement gets turned off as soon as the code reaches the second error statement?

'Private Sub cmdPrint_Click()
'On Error GoTo cmdPrint_Click_Err
'
'
'    On Error Resume Next
'    If (Form.Dirty) Then
'        DoCmd.RunCommand acCmdSaveNow
'    End If
'    If (MacroError.Number <> 0) Then
'        DoCmd.Beep
'        MsgBox MacroError.Description, vbOKOnly, ""
'        Exit Sub
'    End If
'    On Error GoTo 0
'    If (IsNull(ID)) Then
'        DoCmd.Beep
'        Exit Sub
'    End If
'    TempVars.Add "FIlterID", ID.Value
'    DoCmd.Close , ""
'    DoCmd.OpenReport "Task Details", acViewReport, "", "[TaskID]=" & TempVars!FilterID, acNormal
'    DoCmd.RunCommand acCmdPrint
'    DoCmd.OpenForm "frmTaskDetails", acNormal, "", "[TaskID]=" & TempVars!FilterID, , acNormal
'    TempVars.Remove "FIlterID"

'cmdPrint_Click_Exit:
'    Exit Sub
'
'cmdPrint_Click_Err:
'    MsgBox Error$
'    Resume cmdPrint_Click_Exit
'
'End Sub
