The LaunchPage Method

[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 It has been superseded by MediaPlayer.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 LaunchPage method provides the primary functionality of the plug-in, which is to launch a search page containing information about the artist of the media item passed to the method.

This method is called by the OnSearch method using the current Media object.

The following code is used to implement this method:

void LaunchPage(IWMPMedia *pMedia)
{
    USES_CONVERSION;

    HRESULT hr;
    CComBSTR bstrType;
    CComBSTR bstrArtist;

    // Get the name of the artist.
    bstrType = _T("artist");
    hr = pMedia->getItemInfo(bstrType, &bstrArtist);
    if (SUCCEEDED(hr)) 
    {
        // Create the search URL.
        TCHAR szSearch[MAX_PATH];
        _stprintf_s(szSearch, MAX_PATH, _T("https://search.msn.com/results.asp?q=%s"), OLE2T(bstrArtist));
        CComBSTR bstrURL = szSearch;

        // Launch the search page.
        m_pPlugin->m_spCore->launchURL(bstrURL);
    }
    else
    {
        MessageBox(_T("Failed to get artist information from media."), _T("Warn"), MB_OK | MB_ICONWARNING);
    }
}
