我们需要在使用Borlands Turbo C ++开发的C \ C ++ Windows XP / Vista应用程序中以编程方式将文件刻录到CD。
最简单，最好的方法是什么？我们更喜欢本机Windows API（不依赖于MFC），以便不依赖任何第三方软件/驱动程序（如果有的话）。

我们使用了以下内容：
将文件存储在GetBurnPath返回的目录中，然后使用Burn进行写入。 GetCDRecordableInfo用于检查CD何时就绪。
#include <stdio.h>
#include <imapi.h>
#include <windows.h>
struct MEDIAINFO {
BYTE nSessions;
BYTE nLastTrack;
ULONG nStartAddress;
ULONG nNextWritable;
ULONG nFreeBlocks;
};

为了补充已接受的答案，我们添加了这个辅助函数，以编程方式动态更改刻录目录，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;
}

您应该能够使用shell的ICDBurn界面。回到XP日，MFC甚至没有任何CD刻录类。我会看看能不能为你找到一些例子，但是自从我看到它以来已经有一段时间了。
