The GetOccurrence method gets the specific instance of a recurring appointment, occurring on a specific date. Changes to the appointment then apply only to that occurance. If no exception to a recurring pattern exists, a change creates a new exception; otherwise, it modifies an existing exception.

Syntax

HRESULT GetOccurrence(
  DATE date,
  IAppointment ** ppolAppt
);

Parameters

date
[in] Reference to the date object that defines the local date and time of the appointment.
ppolAppt
[out] Reference to the Appointment retrieved by this method.

Return Values

S_OK
The method completed successfully.

void ChangeRecurrence(IAppointment * pAppt)
{
    IPOutlookApp * polApp;
    IRecurrencePattern * pRec;
    IAppointment * pAppt2;
    SYSTEMTIME st = {0};
    DATE date;

    // Get the IPOutlookApp object and a Recurrence Pattern object.
    pAppt->get_Application(&polApp);
    pAppt->GetRecurrencePattern(&pRec);

    // Using the Recurrence Pattern object, get a specific instance of the recurring appointment.
    st.wMonth = 4;
    st.wDay   = 5;
    st.wYear  = 1999;
    polApp->SystemTimeToVariantTime(&st, &date);
    pRec->GetOccurrence(date, &pAppt2);

    // Change the appointment's Start time,and generate an Appointment exception.
    st.wHour = 11;
    polApp->SystemTimeToVariantTime(&st, &date);
    pAppt2->put_Start(date);

    // Save the new Appointment item.
    pAppt2->Save();

    // Release objects.
    polApp->Release();
    pRec->Release();
