予定の管理
Windows.ApplicationModel.Appointments 名前空間を使用して、ユーザーの予定表アプリで予定を作成および管理できます。 ここでは、予定を作成する方法、予定表アプリに追加する方法、予定表アプリで置き換える方法、予定表アプリから削除する方法を示します。 また、カレンダー アプリの一定の期間を表示し、予定の繰り返しオブジェクトを作る方法も示します。
予定を作成してデータを適用する
Windows.ApplicationModel.Appointments.Appointment オブジェクトを作成し、変数に割り当てます。 次に、ユーザーが UI を通じて提供した予定のプロパティを Appointment に適用します。
private void Create-Click(object sender, RoutedEventArgs e)

bool isAppointmentValid = true;
var appointment = new Windows.ApplicationModel.Appointments.Appointment();
// StartTime
var date = StartTimeDatePicker.Date;
var time = StartTimeTimePicker.Time;

case 1:
appointment.Sensitivity = Windows.ApplicationModel.Appointments.AppointmentSensitivity.Private;
break;
}
// Uri
if (UriTextBox.Text.Length > 0)
{
try
{
appointment.Uri = new System.Uri(UriTextBox.Text);
}
catch (Exception)
{
isAppointmentValid = false;
ResultTextBlock.Text = "The Uri provided is invalid.";
}
}
// Organizer
// Note: Organizer can only be set if there are no invitees added to this appointment.
if (OrganizerRadioButton.IsChecked.Value)
{
var organizer = new Windows.ApplicationModel.Appointments.AppointmentOrganizer();

}
if (isAppointmentValid)
{
ResultTextBlock.Text = "The appointment was created successfully and is valid.";
}
}
予定をユーザーのカレンダーに追加する
Windows.ApplicationModel.Appointments.Appointment オブジェクトを作成し、変数に割り当てます。 次に、AppointmentManager.ShowAddAppointmentAsync(Appointment, Rect, Placement) メソッドを呼び出して、既定の予定プロバイダーの予定追加 UI を表示し、ユーザーが予定を追加できるようにします。 ユーザーが [追加] をクリックした場合、このサンプルは ShowAddAppointmentAsync によって返された予定識別子を出力します。
private async void Add-Click(object sender, RoutedEventArgs e)
{
// Create an Appointment that should be added the user's appointments provider app.
var appointment = new Windows.ApplicationModel.Appointments.Appointment();
// Get the selection rect of the button pressed to add this appointment
var rect = GetElementRect(sender as FrameworkElement);
// ShowAddAppointmentAsync returns an appointment id if the appointment given was added to the user's calendar.
// This value should be stored in app data and roamed so that the appointment can be replaced or removed in the future.
// An empty string return value indicates that the user canceled the operation before the appointment was added.
String appointmentId = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowAddAppointmentAsync(
appointment, rect, Windows.UI.Popups.Placement.Default);
if (appointmentId != String.Empty)
{
ResultTextBlock.Text = "Appointment Id: " + appointmentId;
}
else
{
ResultTextBlock.Text = "Appointment not added.";
}
}
注 Windows Phone ストア アプリでは、ShowAddAppointment は、予定を追加するために表示されるダイアログが編集可能であるという点で、ShowEditNewAppointment と同じように機能します。
ユーザーのカレンダーで予定を置換する
Windows.ApplicationModel.Appointments.Appointment オブジェクトを作成し、変数に割り当てます。 次に、該当する AppointmentManager.ShowReplaceAppointmentAsync メソッドを呼び出して、既定の予定プロバイダーの予定置換 UI を表示し、ユーザーが予定を置換できるようにします。 ユーザーは、置換する予定識別子も指定します。 この識別子は、AppointmentManager.ShowAddAppointmentAsync から返されたものです。 ユーザーが [置換] をクリックした場合、このサンプルは更新されたその予定識別子を出力します。
private async void Replace-Click(object sender, RoutedEventArgs e)
{
// The appointment id argument for ReplaceAppointmentAsync is typically retrieved from AddAppointmentAsync and stored in app data.
String appointmentIdOfAppointmentToReplace = AppointmentIdTextBox.Text;
if (String.IsNullOrEmpty(appointmentIdOfAppointmentToReplace))
{
ResultTextBlock.Text = "The appointment id cannot be empty";
}
else
{
// The Appointment argument for ReplaceAppointmentAsync should contain all of the Appointment' s properties including those that may have changed.
var appointment = new Windows.ApplicationModel.Appointments.Appointment();
// Get the selection rect of the button pressed to replace this appointment
var rect = GetElementRect(sender as FrameworkElement);
// ReplaceAppointmentAsync returns an updated appointment id when the appointment was successfully replaced.
// The updated id may or may not be the same as the original one retrieved from AddAppointmentAsync.
// An optional instance start time can be provided to indicate that a specific instance on that date should be replaced
// in the case of a recurring appointment.
// If the appointment id returned is an empty string, that indicates that the appointment was not replaced.
String updatedAppointmentId;
if (InstanceStartDateCheckBox.IsChecked.Value)
{
// Replace a specific instance starting on the date provided.
var instanceStartDate = InstanceStartDateDatePicker.Date;
updatedAppointmentId = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowReplaceAppointmentAsync(
appointmentIdOfAppointmentToReplace, appointment, rect, Windows.UI.Popups.Placement.Default, instanceStartDate);
}
else
{
// Replace an appointment that occurs only once or in the case of a recurring appointment, replace the entire series.
updatedAppointmentId = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowReplaceAppointmentAsync(
appointmentIdOfAppointmentToReplace, appointment, rect, Windows.UI.Popups.Placement.Default);
}
if (updatedAppointmentId != String.Empty)
{
ResultTextBlock.Text = "Updated Appointment Id: " + updatedAppointmentId;
}
else
{
ResultTextBlock.Text = "Appointment not replaced.";
}
}
}
ユーザーのカレンダーから予定を削除する
該当する AppointmentManager.ShowRemoveAppointmentAsync メソッドを呼び出して、既定の予定プロバイダーの予定削除 UI を表示し、ユーザーが予定を削除できるようにします。 ユーザーは、削除する予定識別子も指定します。 この識別子は、AppointmentManager.ShowAddAppointmentAsync から返されたものです。 ユーザーが [削除] をクリックした場合、このサンプルは、その予定識別子により指定された予定が削除されたことを出力します。
private async void Remove-Click(object sender, RoutedEventArgs e)
{
// The appointment id argument for ShowRemoveAppointmentAsync is typically retrieved from AddAppointmentAsync and stored in app data.
String appointmentId = AppointmentIdTextBox.Text;
// The appointment id cannot be null or empty.
if (String.IsNullOrEmpty(appointmentId))
{
ResultTextBlock.Text = "The appointment id cannot be empty";
}
else
{
// Get the selection rect of the button pressed to remove this appointment
var rect = GetElementRect(sender as FrameworkElement);
// ShowRemoveAppointmentAsync returns a boolean indicating whether or not the appointment related to the appointment id given was removed.
// An optional instance start time can be provided to indicate that a specific instance on that date should be removed
// in the case of a recurring appointment.
bool removed;
if (InstanceStartDateCheckBox.IsChecked.Value)
{
// Remove a specific instance starting on the date provided.
var instanceStartDate = InstanceStartDateDatePicker.Date;
removed = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowRemoveAppointmentAsync(
appointmentId, rect, Windows.UI.Popups.Placement.Default, instanceStartDate);
}
else
{
// Remove an appointment that occurs only once or in the case of a recurring appointment, replace the entire series.
removed = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowRemoveAppointmentAsync(
appointmentId, rect, Windows.UI.Popups.Placement.Default);
}
if (removed)
{
ResultTextBlock.Text = "Appointment removed";
}
else
{
ResultTextBlock.Text = "Appointment not removed";
}
}
}
予定プロバイダーの一定の期間を表示する
ユーザーが [表示] をクリックした場合、AppointmentManager.ShowTimeFrameAsync メソッドを呼び出して、既定の予定プロバイダーのプライマリ UI の一定期間を表示します。 このサンプルは、既定の予定プロバイダーが画面に表示されたことを出力します。
private async void Show-Click(object sender, RoutedEventArgs e)
{
var dateToShow = new DateTimeOffset(2015, 6, 12, 18, 32, 0, 0, TimeSpan.FromHours(-8));
var duration = TimeSpan.FromHours(1);
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowTimeFrameAsync(dateToShow, duration);
ResultTextBlock.Text = "The default appointments provider should have appeared on screen.";
}
予定の繰り返しオブジェクトを作成してデータを適用する
Windows.ApplicationModel.Appointments.AppointmentRecurrence オブジェクトを作成し、変数に割り当てます。 次に、ユーザーが UI を通じて提供した繰り返しのプロパティを AppointmentRecurrence に適用します。
private void Create-Click(object sender, RoutedEventArgs e)
{
bool isRecurrenceValid = true;
var recurrence = new Windows.ApplicationModel.Appointments.AppointmentRecurrence();
// Unit
switch (UnitComboBox.SelectedIndex)
{
case 0:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Daily;
break;
case 1:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Weekly;
break;
case 2:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Monthly;
break;
case 3:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.MonthlyOnDay;
break;
case 4:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Yearly;
break;
case 5:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.YearlyOnDay;
break;
}
// Occurrences
// Note: Occurrences and Until properties are mutually exclusive.
if (OccurrencesRadioButton.IsChecked.Value)
{
recurrence.Occurrences = (uint)OccurrencesSlider.Value;
}
// Until
// Note: Until and Occurrences properties are mutually exclusive.
if (UntilRadioButton.IsChecked.Value)
{
recurrence.Until = UntilDatePicker.Date;
}
// Interval
recurrence.Interval = (uint)IntervalSlider.Value;
// Week of the month
switch (WeekOfMonthComboBox.SelectedIndex)
{
case 0:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.First;
break;
case 1:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Second;
break;
case 2:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Third;
break;
case 3:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Fourth;
break;
case 4:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Last;
break;
}
// Days of the Week
// Note: For Weekly, MonthlyOnDay or YearlyOnDay recurrence unit values, at least one day must be specified.
if (SundayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Sunday; }
if (MondayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Monday; }
if (TuesdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Tuesday; }
if (WednesdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Wednesday; }
if (ThursdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Thursday; }
if (FridayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Friday; }
if (SaturdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Saturday; }
if (((recurrence.Unit == Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Weekly) ||
(recurrence.Unit == Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.MonthlyOnDay) ||
(recurrence.Unit == Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.YearlyOnDay)) &&
(recurrence.DaysOfWeek == Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.None))
{
isRecurrenceValid = false;
ResultTextBlock.Text = "The recurrence specified is invalid. For Weekly, MonthlyOnDay or YearlyOnDay recurrence unit values, " +
"at least one day must be specified.";
}
// Month of the year
recurrence.Month = (uint)MonthSlider.Value;
// Day of the month
recurrence.Day = (uint)DaySlider.Value;
if (isRecurrenceValid)
{
ResultTextBlock.Text = "The recurrence specified was created successfully and is valid.";
}
}
新しい編集可能な予定を追加する
ShowEditNewAppointmentAsync の動作は、基本的には ShowAddAppointmentAsync と同じです。異なるのは、予定を追加するためのダイアログが編集可能である点です。ユーザーは、予定のデータを編集したうえで保存することができます。
private async void AddAndEdit-Click(object sender, RoutedEventArgs e)
{
// Create an Appointment that should be added the user' s appointments provider app.
var appointment = new Windows.ApplicationModel.Appointments.Appointment();
appointment.StartTime = DateTime.Now + TimeSpan.FromDays(1);
appointment.Duration = TimeSpan.FromHours(1);
appointment.Location = "Meeting location";
appointment.Subject = "Meeting subject";
appointment.Details = "Meeting description";
appointment.Reminder = TimeSpan.FromMinutes(15); // Remind me 15 minutes prior
// ShowAddAppointmentAsync returns an appointment id if the appointment given was added to the user' s calendar.
// This value should be stored in app data and roamed so that the appointment can be replaced or removed in the future.
// An empty string return value indicates that the user canceled the operation before the appointment was added.
String appointmentId =
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowEditNewAppointmentAsync(appointment);
if (appointmentId != String.Empty)
{
ResultTextBlock.Text = "Appointment Id: " + appointmentId;
}
else
{
ResultTextBlock.Text = "Appointment not added.";
}
}
予定の詳しい情報を表示する
ShowAppointmentDetailsAsync は、指定された予定の詳しい情報を表示するようにシステムに働きかけます。 カレンダーを実装するアプリでは、所有下にあるカレンダー内の予定について詳しい情報を表示するときに、そのアプリをアクティブにするかどうかを選ぶことができます。 それ以外の場合、予定の詳しい情報がシステムによって表示されます。 開始日を引数として受け取るメソッドのオーバーロードが用意されており、定期的に発生する予定について、詳しい情報をいつから表示するかを指定することができます。
private async void ShowAppointmentDetails-Click(object sender, RoutedEventArgs e)
{
if (instanceStartTime == null)
{
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowAppointmentDetailsAsync(
currentAppointment.LocalId);
}
else
{
// Specify a start time to show an instance of a recurring appointment
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowAppointmentDetailsAsync(
currentAppointment.LocalId, instanceStartTime);
}
}
まとめと次のステップ
これで、予定を管理する方法の基本について理解できました。 予定を管理する方法のその他の例については、GitHub からユニバーサル Windows アプリのサンプルをダウンロードしてください。
