Example

The following code example demonstrates how to use SHNotificationAdd.

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.
