REGDB_E_CLASSNOTREG on CLSID_WICPngDecoder

Question

I am trying to load PNGs for HBITMAP. I found this post from stackoverflow. When I run the code I get REGDB_E_CLASSNOTREG on CoCreateInstance(CLSID_WICPngDecoder, NULL, CLSCTX_INPROC_SERVER, __uuidof(ipDecoder), reinterpret_cast<void**>(&ipDecoder). I am using Visual Studio 2012 RC, I've done CoInitlaize and I am still getting same error what could be possibly wrong?

Answer 1

WIC API suggest that you create decoder from factory, rather than directly using its CLSID. See IWICImagingFactory interface and sample code there.

You have options to create from file, stream or specifying container format GUID.
