API записи компакт-дисков Windows

Вы должны иметь возможность использовать интерфейс оболочки ICDBurn. Во времена XP в MFC даже не было классов для записи компакт-дисков. Я посмотрю, смогу ли я найти для вас несколько примеров, но я давно не смотрел на это.

Мы использовали следующее:

Сохраните файлы в каталоге, возвращаемом GetBurnPath, затем напишите с помощью Burn. GetCDRecordableInfo используется для проверки готовности компакт-диска.

В дополнение к принятому ответу мы добавили эту вспомогательную функцию для программного изменения каталога записи на лету, поскольку это было нашим требованием.

typedef HMODULE (WINAPI * SHSETFOLDERPATHA)( int , HANDLE , DWORD , LPCTSTR );

int SetBurnPath( char * cpPath )
{
    SHSETFOLDERPATHA pSHSetFolderPath;
    HANDLE hShell = LoadLibraryA( "shell32.dll" );
    if ( hShell == NULL )
        return -2;

    DWORD dwOrdinal = 0x00000000 + 231;

    pSHSetFolderPath = (SHSETFOLDERPATHA)GetProcAddress( hShell, (LPCSTR)dwOrdinal );
    if ( pSHSetFolderPath == NULL )
        return -3;

    if ( pSHSetFolderPath( CSIDL_CDBURN_AREA, NULL, 0, cpPath ) == S_OK )
        return 0;

    return -1;
}
