To use the save email address task

Add the following statement to your code.

using Microsoft.Phone.Tasks;

Imports Microsoft.Phone.Tasks

Declare the task object. It must have page scope, so declare it in your page before the constructor.
```
SaveEmailAddressTask saveEmailAddressTask;
```
```
Dim saveEmailAddressTask As SaveEmailAddressTask
```

Add the following code to your page constructor. This code initializes the task object, and identifies the method to run after the user completes the task.

saveEmailAddressTask = new SaveEmailAddressTask();
saveEmailAddressTask.Completed += new EventHandler<TaskEventArgs>(saveEmailAddressTask_Completed);

saveEmailAddressTask = new SaveEmailAddressTask()
AddHandler saveEmailAddressTask.Completed, AddressOf saveEmailAddressTask_Completed

Add the following code to your application wherever you need it, such as in a button click event. To test this procedure, you can put the code in the page constructor. This is the code to launch the task.

You can pre-populate the email address, but it is not required. The user can add or edit the email address before saving.
```
saveEmailAddressTask.Email = "someone@example.com";

saveEmailAddressTask.Show();
```
```
saveEmailAddressTask.Email = "someone@example.com"

saveEmailAddressTask.Show()
```

Add the code for the completed event handler to your page. This code runs after the user completes the task. You can check to see whether the email was saved successfully.

void saveEmailAddressTask_Completed(object sender, TaskEventArgs e)
{
    switch (e.TaskResult)
    {
        //Logic for when the email was saved successfully
        case TaskResult.OK:
            MessageBox.Show("Email saved.");
            break;

        //Logic for when the task was cancelled by the user
        case TaskResult.Cancel:
            MessageBox.Show("Save cancelled.");
            break;

        //Logic for when the email could not be saved
        case TaskResult.None:
            MessageBox.Show("Email could not be saved.");
            break;
    }
}

Private Sub saveEmailAddressTask_Completed(sender As Object, e As TaskEventArgs)

    Select Case e.TaskResult

        'Logic for when the email was saved successfully
        Case TaskResult.OK

            MessageBox.Show("Email saved.")

        'Logic for when the task was cancelled by the user
        Case TaskResult.Cancel

            MessageBox.Show("Save cancelled.")

        'Logic for when the email could not be saved
        Case TaskResult.None

            MessageBox.Show("Email could not be saved.")
    End Select
End Sub
