Windows CD刻录API

我们使用了以下内容：

将文件存储在由GetBurnPath返回的目录中，然后使用刻录进行写入。 GetCDRecordableInfo用于检查CD何时准备就绪。

为了补充接受的答案，我们添加了这个辅助函数，以编程方式更改燃烧目录，因为这是我们的要求。

 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; } 

你应该可以使用shell的ICDBurn接口。 回到XP日，MFC甚至没有任何CD刻录类。 我会看看能不能找到一些例子，但是我看了这一段时间已经有一段时间了。

找到一些示例代码给你。 http://msdn.microsoft.com/en-us/magazine/cc163992.aspx
