Outlook VBA - Exécuter un code toutes les demi-heures

http://www.outlookcode.com/threads.aspx?forumid=2&messageid=7964

placer le code suivant dans le module ThisOutlookSession (Tools - > Macros - >VB Editor):

Private Sub Application_Quit()
  If TimerID <> 0 Then Call DeactivateTimer 'Turn off timer upon quitting **VERY IMPORTANT**
End Sub

Private Sub Application_Startup()
  MsgBox "Activating the Timer."
  Call ActivateTimer(1) 'Set timer to go off every 1 minute
End Sub

placer le code suivant dans un nouveau module VBA

Declare Function SetTimer Lib "user32" (ByVal hwnd As Long, ByVal nIDEvent As Long, ByVal uElapse As Long, ByVal lpTimerfunc As Long) As Long
Declare Function KillTimer Lib "user32" (ByVal hwnd As Long, ByVal nIDEvent As Long) As Long

Public TimerID As Long 'Need a timer ID to eventually turn off the timer. If the timer ID <> 0 then the timer is running

Public Sub ActivateTimer(ByVal nMinutes As Long)
  nMinutes = nMinutes * 1000 * 60 'The SetTimer call accepts milliseconds, so convert to minutes
  If TimerID <> 0 Then Call DeactivateTimer 'Check to see if timer is running before call to SetTimer
  TimerID = SetTimer(0, 0, nMinutes, AddressOf TriggerTimer)
  If TimerID = 0 Then
    MsgBox "The timer failed to activate."
  End If
End Sub

Public Sub DeactivateTimer()
Dim lSuccess As Long
  lSuccess = KillTimer(0, TimerID)
  If lSuccess = 0 Then
    MsgBox "The timer failed to deactivate."
  Else
    TimerID = 0
  End If
End Sub

Public Sub TriggerTimer(ByVal hwnd As Long, ByVal uMsg As Long, ByVal idevent As Long, ByVal Systime As Long)
  MsgBox "The TriggerTimer function has been automatically called!"
End Sub

points clés:

1) Cette fonction de minuterie n'exige pas qu'une fenêtre est ouverte; il fonctionne en arrière-plan

2) Si vous ne désactivez pas la minuterie de l'application ferme, il ne sera probablement crash

3) l'exemple montre le timer activé au démarrage, mais il peut tout aussi bien être appelé par un événement différent

4) Si vous ne voyez pas la msgbox indiquant que le minuteur a été activé au démarrage, votre macro sécurité est réglée trop haut

5) pour que le timer soit désactivé après une itération de l'intervalle de temps ajouter: si TimerID < > 0 puis appeler DeactivateTimer après la déclaration msgbox dans sub TriggerTimer

Quelqu'un d'autre a suggéré

"un point à noter, si vous ne cochez pas si TimerID est le même que idevent dans le TriggerTimer, vous obtenez chaque tellement souvent, et pas le temps que vous avez demandé."

Public Sub TriggerTimer(ByVal hwnd As Long, ByVal uMsg As Long, ByVal idevent As Long, ByVal Systime As Long)
    'keeps calling every X Minutes unless deactivated
    If idevent = TimerID Then
        MsgBox "The TriggerTimer function has been automatically called!"
    End If
End Sub

pour Win64, je devais le changer en ceci:

Declare PtrSafe Function SetTimer Lib "user32" (ByVal hwnd As LongLong, ByVal nIDEvent As LongLong, ByVal uElapse As LongLong, ByVal lpTimerfunc As LongLong) As LongLong
Declare PtrSafe Function KillTimer Lib "user32" (ByVal hwnd As LongLong, ByVal nIDEvent As LongLong) As LongLong

Public TimerID As LongLong 'Need a timer ID to eventually turn off the timer. If the timer ID <> 0 then the timer is running

Public Sub TriggerTimer(ByVal hwnd As Long, ByVal uMsg As Long, ByVal idevent As Long, ByVal Systime As Long)
  MsgBox "The TriggerTimer function has been automatically called!"
End Sub


Public Sub DeactivateTimer()
Dim lSuccess As LongLong
  lSuccess = KillTimer(0, TimerID)
  If lSuccess = 0 Then
    MsgBox "The timer failed to deactivate."
  Else
    TimerID = 0
  End If
End Sub

Public Sub ActivateTimer(ByVal nMinutes As Long)
  nMinutes = nMinutes * 1000 * 60 'The SetTimer call accepts milliseconds, so convert to minutes
  If TimerID <> 0 Then Call DeactivateTimer 'Check to see if timer is running before call to SetTimer
  TimerID = SetTimer(0, 0, nMinutes, AddressOf TriggerTimer)
  If TimerID = 0 Then
    MsgBox "The timer failed to activate."
  End If
End Sub

Correct pour le haut de réponse pour la version 64 bits:

Declare PtrSafe Function SetTimer Lib "user32" (ByVal hwnd As LongLong, ByVal nIDEvent As LongLong, ByVal uElapse As LongLong, ByVal lpTimerfunc As LongLong) As LongLong
Declare PtrSafe Function KillTimer Lib "user32" (ByVal hwnd As LongLong, ByVal nIDEvent As LongLong) As LongLong

Public TimerID As LongLong 'Need a timer ID to eventually turn off the timer. If the timer ID <> 0 then the timer is running

Public Sub TriggerTimer(ByVal hwnd As Long, ByVal uMsg As Long, ByVal idevent As Long, ByVal Systime As Long)
  MsgBox "The TriggerTimer function has been automatically called!"
End Sub


Public Sub DeactivateTimer()
Dim lSuccess As LongLong              '<~ Corrected here
  lSuccess = KillTimer(0, TimerID)
  If lSuccess = 0 Then
    MsgBox "The timer failed to deactivate."
  Else
    TimerID = 0
  End If
End Sub

Public Sub ActivateTimer(ByVal nMinutes As Long)
  nMinutes = nMinutes * 1000 * 60 'The SetTimer call accepts milliseconds, so convert to minutes
  If TimerID <> 0 Then Call DeactivateTimer 'Check to see if timer is running before call to SetTimer
  TimerID = SetTimer(0, 0, nMinutes, AddressOf TriggerTimer)
  If TimerID = 0 Then
    MsgBox "The timer failed to activate."
  End If
End Sub
