將exe檔案剝離出swf檔案

說明：該程式是將用Flash編寫的，並被發布成exe檔案的小遊戲（如早先的著名遊戲《機械迷城》）剝離成SWF檔案，純屬娛樂小遊戲，寫著玩的，演算法就不講了，看看代碼就明白了。運行環境Visual Studio C++ 2005；直接上代碼

#include "stdafx.h"
#include <windows.h>

// swf檔案玩具
typedef struct tagswfID {
    unsigned long int   id;
    unsigned long int   swfFileSize;
} SWFID;

int _tmain(int argc, _TCHAR* argv[])
{
    // 玩具程式2----將一個可執行檔的exe轉成swf檔案；針對某些用Flash編寫的遊戲並被最終發布為exe檔案，該程式可以自動剝離出swf檔案
    // 惡作劇程式，愚人節禮物，但絕對可用
    // 要轉換的可執行swf檔案（尾碼名.exe）
    const char iswfFileName[] = "Samorost2.exe"; //原始SWF檔案
    HANDLE hFile = CreateFile(iswfFileName, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING,
        FILE_ATTRIBUTE_NORMAL, NULL);
    if(hFile != INVALID_HANDLE_VALUE)
        {
        int nFileSize = GetFileSize(hFile, NULL);
        SetFilePointer(hFile, nFileSize - 8, NULL, FILE_BEGIN);
       
        SWFID swfid;
        DWORD NumberOfBytesRead;
        if( ReadFile(hFile, &swfid, 8, &NumberOfBytesRead, NULL) )
            {
            if(NumberOfBytesRead == 8 && swfid.id == 0xFA123456 )
                {
                // 移動到該swf檔案頭，並產生新的swf檔案
                SetFilePointer(hFile, nFileSize - swfid.swfFileSize - 8, NULL, FILE_BEGIN);
                unsigned char *buffer = NULL;
                buffer = (unsigned char *)malloc(swfid.swfFileSize + 16);
                ReadFile(hFile, buffer, swfid.swfFileSize, &NumberOfBytesRead, NULL);

                const char outputFile[] = "outswffile.swf"; // 輸出的SWF檔案
                HANDLE hswfFile = CreateFile(outputFile, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_FLAG_WRITE_THROUGH, NULL);
                if(hswfFile != INVALID_HANDLE_VALUE)
                    {
                    DWORD nWriteBytes;
                    WriteFile(hswfFile, buffer, swfid.swfFileSize, &nWriteBytes, NULL);
                    CloseHandle(hswfFile);
                    }
                free(buffer);
                }
            }

        CloseHandle(hFile);
        }

     return 1;
}
