加载资源，然后写成文件

gistfile1.txt

    HINSTANCE instance = AfxGetInstanceHandle();
    // 定位资源
    HRSRC hRsrc = FindResource(instance, MAKEINTRESOURCE(IDR_FILE1), _T("File"));

    // 获取资源大小
    DWORD dwSize = SizeofResource(instance, hRsrc);
    assert(dwSize != 0);

    // 加载资源
    HGLOBAL hGlobal = LoadResource(instance, hRsrc);
    assert(hGlobal != NULL);

    // 锁定资源
    LPVOID pBuffer = LockResource(hGlobal);
    assert(pBuffer != NULL);

    FILE* f = fopen("d:\\aa.exe","wb");
    assert(f != NULL);

    fwrite(pBuffer, dwSize, 1, f);

    fclose(f);
