Creating an HICON from a byte array in C++?
I have a PNG-encoded icon as a byte array in memory. What is the recommended way of creating an HICON object from this byte array?
Imaginary bonus points if you know a solution without ATL o开发者_运维知识库r GDI+... :)
HGLOBAL hMem = GlobalAlloc(GMEM_MOVEABLE, dataSize);
LPVOID pImage = GlobalLock(hMem);
memcpy(pImage, pngData, dataSize);
GlobalUnlock(hMem);
ATL::CComPtr<IStream> pStream;
CreateStreamOnHGlobal(hMem, TRUE, &pStream);
Gdiplus::Bitmap *pBitmap = new Gdiplus::Bitmap(pStream);
HICON YOUR_HICON = pBitmap->GetHICON();
It looks like you could do this with CreateBitmap and CreateIconIndirect, or maybe even just CreateIcon. Don't ask me for code because I'm not really familiar with this low-level graphics stuff.
