How can I create a bitmap from bytes array of png image in C++

Question

Tried using the below code but it does not seem to work. The value of bm is null

BYTE imageData[] =
    {
    0x89, 0x50, 0x4e, 0x47, 0x0d, 0x0a, 0x1a, 0x0a, 0x00, 0x00, 0x00, 0x0d, 0x49, 0x48, 0x44, 0x52, 0x00, 0x00, 0x00,
    0x10, 0x00, 0x00, 0x00, 0x0f, 0x04, 0x03, 0x00, 0x00, 0x00, 0x1f, 0x5d, 0x52, 0x1c, 0x00, 0x00, 0x00, 0x0f, 0x50,
    0x4c, 0x54, 0x45, 0x7a, 0xdf, 0xfd, 0xfd, 0xff, 0xfc, 0x39, 0x4d, 0x52, 0x19, 0x16, 0x15, 0xc3, 0x8d, 0x76, 0xc7,
    0x36, 0x2c, 0xf5, 0x00, 0x00, 0x00, 0x40, 0x49, 0x44, 0x41, 0x54, 0x08, 0xd7, 0x95, 0xc9, 0xd1, 0x0d, 0xc0, 0x20,
    0x0c, 0x03, 0xd1, 0x23, 0x5d, 0xa0, 0x49, 0x17, 0x20, 0x4c, 0xc0, 0x10, 0xec, 0x3f, 0x53, 0x8d, 0xc2, 0x02, 0x9c,
    0xfc, 0xf1, 0x24, 0xe3, 0x31, 0x54, 0x3a, 0xd1, 0x51, 0x96, 0x74, 0x1c, 0xcd, 0x18, 0xed, 0x9b, 0x9a, 0x11, 0x85,
    0x24, 0xea, 0xda, 0xe0, 0x99, 0x14, 0xd6, 0x3a, 0x68, 0x6f, 0x41, 0xdd, 0xe2, 0x07, 0xdb, 0xb5, 0x05, 0xca, 0xdb,
    0xb2, 0x9a, 0xdd, 0x00, 0x00, 0x00, 0x00, 0x49, 0x45, 0x4e, 0x44, 0xae, 0x42, 0x60, 0x82
    };
    HGLOBAL hMem = ::GlobalAlloc(GMEM_MOVEABLE, sizeof(imageData)); 
    LPVOID pImage = ::GlobalLock(hMem);
    memcpy(pImage, imageData, sizeof(imageData)); 

    IStream* pStream = NULL;
    ::CreateStreamOnHGlobal(hMem, FALSE, &pStream);
    Gdiplus::Bitmap* bm = Gdiplus::Bitmap::FromStream(pStream, true);

Probably you did not initialise the engine at startup:

ULONG_PTR t;
Gdiplus::GdiplusStartupInput s;
Gdiplus::GdiplusStartup( &t, &s, nullptr );
