Members
ActionFlags
Specifies the action to take when a notification event occurs. It can be a combination of the following flags:
| Value | Description |
| PUN_LED | Flashes the LED. |
| PUN_VIBRATE | Vibrates the device. |
| PUN_DIALOG | Displays the user notification dialog box. When this structure is passed to the CeSetUserNotification function, the pwszDialogTitle and pwszDialogText members must provide the title and text of the dialog box. |
| PUN_SOUND | Plays the sound specified by the pwszSound member. When passed to PSVN, the pwszSound member must provide the name of the sound file. |
| PUN_REPEAT | Repeats the pwszSound for 10–15 seconds. Only valid if PUN_SOUND is set. |
Any flag that is not valid on the current hardware platform is ignored.
pwszDialogTitle
Pointer to the string that contains the title of the user notification dialog box. If this member is NULL, no dialog is displayed. The CeGetUserNotificationPreferences function ignores this member.
pwszDialogText
Pointer to the string that contains the text of the user notification dialog box. If this member is NULL, no dialog is displayed. The CeGetUserNotificationPreferences function ignores this member.
pwszSound
Pointer to a buffer that contains the unqualified name of a sound file to play. This member is ignored if the ActionFlags member does not include the PUN_SOUND flag.
nMaxSound
Specifies the maximum length of the string that the CeGetUserNotificationPreferences function can copy into the pwszSound buffer. Because the string may be a path name in a future release, the buffer must be at least the length derived by the following expression: PATH_MAX * sizeof(TCHAR). This member is ignored by the CeSetUserNotification function.
dwReserved
Reserved; set to zero.
Remarks
The CE_USER_NOTIFICATION structure is passed in the CeGetUserNotificationPreferences function. Initial settings are used to populate the dialog box. If the function returns TRUE, the returned settings should be saved, and considered when calling CeSetUserNotification. Settings for hardware not on the current device will be ignored.
It is also used when calling CeSetUserNotification, to describe what should happen when the notification time is reached.
