SHNotificationAdd在WINCE 5.0 .net下不弹出气泡通知

如下代码在windows mobile手机上是可以弹出气泡的，但是在wince 5.0开发板上弹不出来.根据MSDN似乎应该是可以的。 SHNP_INFORM Notification bubble displays for the set duration, then disappears. Note For Windows Mobile, this enumerator indicates that a message balloon is shown for the notification, along with an icon in the notification area. SHNOTIFICATIONDATA sn = {0}; sn.cbStruct = sizeof(sn); sn.dwID = 1; sn.npPriority = SHNP_INFORM; sn.csDuration = 15; sn.hicon = LoadIcon(g_hInst, MAKEINTRESOURCE(IDI_MYNOTIFICATION)); sn.clsid = CLSID_SHNAPI_Test; sn.grfFlags = 0; sn.pszTitle = TEXT("Sample Notification"); sn.pszHTML = TEXT("This is sample html in a notification!"); SHNotificationAdd(&sn);
