Windows CD刻錄API

Question

我們需要以編程方式將文件刻錄到使用Borlands Turbo C++開發的C \ C++ Windows XP/Vista應用程序中的CD。

什麼是最簡單和最好的方法來做到這一點？我們更喜歡本地Windows API（不依賴於MFC），以便在任何第三方軟件/驅動程序可用時不依賴任何第三方軟件/驅動程序。

Answer 1

我們使用以下：

將文件存儲在由GetBurnPath返回的目錄，然後寫使用燒錄。 GetCDRecordableInfo用於檢查CD何時準備就緒。

#include <stdio.h> 
#include <imapi.h> 
#include <windows.h>

    BYTE nSessions; 
    BYTE nLastTrack; 
    ULONG nStartAddress; 
    ULONG nNextWritable; 
    ULONG nFreeBlocks; 
};

Answer 2

你應該可以使用shell的ICDBurn接口。回到XP日，MFC甚至沒有任何CD刻錄類。我會看看我能否爲你找到一些例子，但是從我看過這個過程已經有一段時間了。

Answer 5

爲了配合接受的答案，我們添加了這個輔助函數來編程更改動態燒傷目錄，因爲這是我們的一個要求。

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; 
}
