This function gets the data for a notification. It is available for querying back the data to another application.

Syntax

LRESULT SHNotificationGetData(
  const CLSID * pclsid,
  DWORD dwID,
  SHNOTIFICATIONDATA* pndBuffer
);

Parameters

pclsid
[in] Pointer to the class ID of the notification.

dwID
[in] Specifies the unique identifier for the notification.

pndBuffer
[out] Pointer to an SHNOTIFICATIONDATA buffer to receive the notification data.

Return Value

This function returns ERROR_SUCCESS when successful.

Remarks

Upon successful return from this function, pndBuffer->pszHTML and pndBuffer->pszTitle are owned by and must be freed by the caller.

Code Example

The following code example demonstrates how to use SHNotificationGetData.

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 notification 
    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
    SHNotificationAdd(&sn);
    //Put the data from an existing notification into a second SHNOTIFICATIONDATA struct
    sn2.cbStruct = sizeof(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);
}
