How can I create an HICON from an XAML resource?

I've tried

HICON hIcon = (HICON)::LoadImage(theApp.m_hInstance, MAKEINTRESOURCE(IDR_LOGO), IMAGE_ICON, szIcon.cx, szIcon.cy, LR_SHARED);

But hIcon here is NULL.

Is this possible? I am able to add that resource to an image vector and use it for a ribbon without problem.

Hello Duane,

It is possible to make an HICON from XAML by rendering XAML into a bitmap and then making an icon from that bitmap manually. But that is not only a tedious work, but also a useless and pointless one as the whole point of having XAML icons is to ensure that you need only one XAML image to handle or possible icon sizes and to ensure a crisp and scalable image. Look for SetVectorIcon calls in ToolkitPro samples, like RibbonSample and similar.

Regards,

Alexander

Thanks for the reply. I guess my question was poorly worded. I am not specifically looking to convert an XAML into an HICON. I want to be able to use the XAML as the frame icon. I am able to use SetVectorIcon for the ribbon without problem. But the frame icon in the sample is using CXTPFramePaintManager. And this doesn't have a SetVectorIcon member.
