WM 通知、声音和提醒

windows mobile 中，系统定义了许多通知类型，在不同的事件（来电、新短信等）时会抛出相应的通知。这里的通知是广义的，其效果包括:播放声音、振动、在屏幕上显示信息（从屏幕下方弹出一个消息框）、LED灯闪烁，所有这些都被认为是通知。 主要信息存在注册表 [HKEY_CURRENT_USER/ControlPanel/Notifications/{GUID}] ]下 键/值数据解析：[HKEY_CURRENT_USER/ControlPanel/Notifications/{GUID} ]"Wave"="声音文件具体路径，不用带扩展名，例如Sun CF/Mobile.wav就是Sun CF/Mobile""Duration"=指示灯（LED）闪烁时间[以分钟为时间单位，如果=0为无限制]"Options"=[0为静音]，[=1为播放提示声音],[=4为指示灯闪烁，关联到"Duration"REG_DWORD值],[=5即1+4为播放提示声音并带指示灯闪灯][=8在屏幕上显示信息],[=9即1+8,为播放提示声音并在屏幕上显示信息]，[=12=4+8]，[=13=1+4+8]Default="对应发生事件"=如果没有此字符串，不在设定(控制面板‘声音和提示’）中显示选项,但有其它定义例如[HKEY_CURRENT_USER/ControlPanel/Notifications/{A877D663-239C-47a7-9304-0D347F580408}]"Wave"="lowbatt""Duration"=dword:00000000"Options"=dword:00000009 此处为系统电力不足时候的声音事件[=9即1+8,为播放提示声音并在屏幕上显示信息]，如果为了在系统电力不足的时候，不让屏幕上弹出显示信息，又要播放声音得知电力不足的信息，只要将其数值改为1即可，改为0太“危险”[电力不足，而自己仍然做卡上的程序重要操作而没有保存就麻烦了]上面的GUID指定了一类通知的物理效果，可以有不同的通知实例，体现在 SHNOTIFICATIONDATA 中的dwID值不同（有点像窗口类和窗口实例的关系）。 联系下面资料看，增加理解。 SHNotificationAdd

This function adds a notification (asynchronously) to the notification tray.

LRESULT SHNotificationAdd( SHNOTIFICATIONDATA * pndAdd);

Parameters

pndAdd Reference to the notification to be added.

Return Values

ERROR_SUCCESS indicates success.

Remarks

This API is called to add a notification to the tray. Notification processing is done asynchronously; that is, this function will return after adding the notification to the tray, and processing will happen on a different thread.（异步方式，添加到通知托盘与显示通知效果是由不同线程处理的）

To customize the physical behaviour for a notification, create a CLSID for the notification class (passed into SHNotificationAdd), and create the registry key:

[HKEY_CURRENT_USER/ControlPanel/Notifications/{CLSID}]@="Name" ; this is what appears in Settings - if you don't want to allow user customization, don't add this default value"Options"=dword:1 ; notification flags"Duration"=dword:0 ; duration in minutes of LED flashing"Wave"="wavefile" ; default is in the Windows folder. There is no extension on the file

The following table lists the possible values for the Options parameter.

Notification flagValueDescriptionNOTIF_SOUND0x00000001Sound notification.NOTIF_VIBRATE0x00000002Vibrate notification.NOTIF_FLASH0x00000004ROM notification.NOTIF_MESSAGE0x00000008Message notification. 引申的应用：更改低电提示的效果。 注册表找到 [HKEY_CURRENT_USER/ControlPanel/Notifications/{A877D663-239C-47a7-9304-0D347F580408}]项， 将 Default值改成任何名字（只要不为空，空的话在设置里不出现此项），比如“LowBattery”。然后便可以在“设置”--“声音和提醒”--“通知”--“事件”里找到LowBattery项，可以对此类型的通知做更改。比如：播放声音，在屏幕上显示信息（即弹出通知），震动，指示灯闪烁等。注册表里的键与控制面板里的选项是对应的。引申的应用2：弹出一个与低电处理效果类似的通知。 LRESULT SHNotificationAdd( SHNOTIFICATIONDATA * pndAdd);将SHNOTIFICATIONDATA 结构中的clsid项设置成{A877D663-239C-47a7-9304-0D347F580408}对应的GUID值，然后SHNotificationAdd即可。#define Noti_GUID L"{A877D663-239C-47a7-9304-0D347F580408}" GUID myGUID;// Parse the GUIDhr = CLSIDFromString(Noti_GUID, &myGUID);SHNOTIFICATIONDATA sn = {0};sn.cbStruct = sizeof(sn);sn.dwId = SAMPLE_ID_I;sn.clsid = myGUID;sn.npPriority = SHNP_INFORM;sn.csDuration = 5;sn.pszTitle = TEXT("Title");sn.pszHTML = TEXT("Test Notification")sn.grfFlags = SHNF_FORCEMESSAGE;SHNotificationAdd(&sn));其他事件声音和提醒：[HKEY_CURRENT_USER/ControlPanel/Notifications/{F55615D6-D29E-4db8-8C75-98125D1A7253}]"Wave"="Notify""Duration"=dword:00000000"Options"=dword:00000009Default="无线数据交换: 自动接收"[HKEY_CURRENT_USER/ControlPanel/Notifications/{A877D65D-239C-47a7-9304-0D347F580408}]"Wave"="online""Duration"=dword:00000003"Options"=dword:0000000d[HKEY_CURRENT_USER/ControlPanel/Notifications/{A877D659-239C-47a7-9304-0D347F580408}]"Wave"="Infend""Duration"=dword:00000000"Options"=dword:00000001"AvailableOptions"=dword:00000003Default="ActiveSync: 结束同步"[HKEY_CURRENT_USER/ControlPanel/Notifications/{A877D658-239C-47a7-9304-0D347F580408}]"Wave"="infbeg""Duration"=dword:00000000"Options"=dword:00000000"AvailableOptions"=dword:00000003Default="ActiveSync: 开始同步"[HKEY_CURRENT_USER/ControlPanel/Notifications/Reminders]"Wave"="Alarm1""Duration"=dword:0000000a"Options"=dword:4000000dDefault="提醒"[HKEY_CURRENT_USER/ControlPanel/Notifications/{8ddf46e8-56ed-4750-9e58-afc6ce486d03}]"Wave"="infend""Duration"=dword:00000000"Options"=dword:00000000[=1有声音=0无声音]"AvailableOptions"=dword:00000003Default="连接断开"[HKEY_CURRENT_USER/ControlPanel/Notifications/{8ddf46e7-56ed-4750-9e58-afc6ce486d03}]"Wave"="infbeg""Duration"=dword:00000000"Options"=dword:00000008"AvailableOptions"=dword:0000000bDefault="连接成功"[HKEY_CURRENT_USER/ControlPanel/Notifications/{0D3132C4-1298-469c-B2B8-F28CE2D649D0}]"Wave"="infbeg""Duration"=dword:00000000"Options"=dword:00000009[HKEY_CURRENT_USER/ControlPanel/Notifications/{A877D663-239C-47a7-9304-0D347F580408}]"Wave"="lowbatt""Duration"=dword:00000000"Options"=dword:00000009[HKEY_CURRENT_USER/ControlPanel/Notifications/Default]"LedRefCount"=dword:00000000"Wave"="default""Duration"=dword:00000005"Options"=dword:0000000d[HKEY_CURRENT_USER/ControlPanel/Notifications/Sounds]"Repeat"=dword:00000000[HKEY_CURRENT_USER/ControlPanel/Notifications/{A877D65A-239C-47a7-9304-0D347F580408}]"Wave"="notify""Duration"=dword:00000000"Options"=dword:00000009Default="收件箱: 新电子邮件"[HKEY_CURRENT_USER/ControlPanel/Notifications/{A877D65F-239C-47a7-9304-0D347F580408}]"Wave"="type""Duration"=dword:00000000"Options"=dword:00000009Default="MSN Messenger: 新消息"[HKEY_CURRENT_USER/ControlPanel/Notifications/{A877D65E-239C-47a7-9304-0D347F580408}]"Wave"="online""Duration"=dword:00000000"Options"=dword:00000001Default="MSN Messenger: 联系人联机"
