Retrieving the Drive and Disc Status

[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 It has been superseded by MediaPlayer.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.]

Before starting a CD burning operation, you must ensure that the selected CD-ROM drive supports the operation you want to perform. For instance, you must check that a CD is capable of being erased before calling IWMPCdromBurn::erase. The following code shows an example of using IWMPCdromBurn::isAvailable to determine whether an operation is supported:

VARIANT_BOOL vbResult;
    
// Check whether this drive can burn CDs.
CComBSTR bstrItem;
HRESULT hr = bstrItem.Append("Burn");
if (SUCCEEDED(hr))
{
    hr = m_spCdromBurn->isAvailable(bstrItem, &vbResult);
}
if (SUCCEEDED(hr))
{
    if (VARIANT_TRUE == vbResult)
    {
        // The current drive can burn CDs.
    }
}
