Note

To make the following code example easier to read, security checking and error handling are not included. This code example should not be used in a release configuration unless it has been modified to include them.

static const GUID CLSID_SHNAPI_Test = { 0x33765136, 0x8cb9, 0x449a, { 0xb0, 0x20, 0x43, 0xed, 0x40, 0xa, 0xb8, 0xfc } };
void SHNotificationExample()
{
    // This code will add an SHNotification notificaion 
    SHNOTIFICATIONDATA sn  = {0};
    SHNOTIFICATIONDATA sn2 = {0};
    sn.cbStruct = sizeof(sn);
    sn.dwID = 1;
    sn.npPriority = SHNP_INFORM;
    sn.csDuration = 15;
    sn.hicon = LoadIcon(g_hInstance, MAKEINTRESOURCE(IDI_SAMPLEICON));
    sn.clsid = CLSID_SHNAPI_Test;
    sn.grfFlags = 0;
    sn.pszTitle = TEXT("Sample Notification");
    sn.pszHTML = TEXT("<html><body>This is <b>sample html</b> in a notification!</body></html>");
    sn.rgskn[0].pszTitle = TEXT("Dismiss");
    sn.rgskn[0].skc.wpCmd = 100;
    //Add the notification to the tray

    //Put the data from an existing notification into a second SHNOTIFICATIONDATA struct
    sn2.cbStruct = sizeof(sn2);
    SHNotificationGetData(&CLSID_SHNAPI_Test, 1, &sn2);
    //Update the title, HTML, icon, and softkeys of the notification
    sn2.pszTitle = TEXT("Updated - Sample Notification");
    sn2.pszHTML = TEXT("<html><body>This notification has been <b>updated!</b></body></html>");
    sn2.hicon = LoadIcon(g_hInstance, MAKEINTRESOURCE(IDI_SAMPLEICON2));
    sn2.rgskn[0].pszTitle = TEXT("Disabled");
    sn2.rgskn[0].skc.wpCmd = 100;
    sn2.rgskn[0].skc.grfFlags = NOTIF_SOFTKEY_FLAGS_DISABLED;
    SHNotificationUpdate(SHNUM_TITLE | SHNUM_HTML | SHNUM_ICON | SHNUM_SOFTKEYCMDS | SHNUM_SOFTKEYS, &sn2);
    //Remove the notification from the tray
    SHNotificationRemove(&CLSID_SHNAPI_Test, 1);
    //Add a new notification that utilizes the MRE functionality
    sn.cbStruct = sizeof(sn);
    sn.dwID = 1;
    sn.npPriority = SHNP_INFORM;
    sn.csDuration = 15;
    sn.hicon = LoadIcon(g_hInstance, MAKEINTRESOURCE(IDI_SAMPLEICON));
    sn.clsid = CLSID_SHNAPI_Test;
    sn.grfFlags = SHNF_STRAIGHTTOTRAY;
    sn.pszTodaySK = TEXT("New Task");
    sn.pszTodayExec = TEXT("\\windows\\tasks.exe");
    //Add the notification to the tray
    SHNotificationAdd(&sn);
    //Remove the notification from the tray
    SHNotificationRemove(&CLSID_SHNAPI_Test, 1);
}

Remarks

The notification tray is the area within the taskbar reserved by shells to display status notification icons. Call this function 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.

Requirements

Header	aygshell.h
Library	aygshell.lib
