The OnSearch Method

  • Artículo

[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The OnSearch method is called by Windows Media Player when the Search button is clicked. This method retrieves the current Media object and passes it to the LaunchPage method.

The following code is used to implement this method:

LRESULT OnSearch(WORD wNotifyCode, WORD wID, HWND hwndCtl, BOOL& fHandled)
{
    HRESULT hr;
    CComPtr<IWMPMedia> spMedia;

    if( m_pPlugin && m_pPlugin->m_spCore )
    {
        // Get a pointer to the current media item.
        hr = m_pPlugin->m_spCore->get_currentMedia(&spMedia);
        if (SUCCEEDED(hr) && spMedia)
        {
            LaunchPage(spMedia);
        }
    else
        {
            MessageBox(_T("There is no media loaded."), _T("Warn"), MB_OK | MB_ICONWARNING);
        }
    }
    return 0;
}
