I may have completely missed something here, but you are serializing only a
handle, not an entire icon.

When you unserialize the handle it's going to be meaningless unless just by
coincidence, there's an icon loaded with the same handle value.

I'm using standard MFC serialization mechanism to save an icon.
After upgrade to VS 2008 my serialization code stop working.
Saving seems to work fine, but when it comes to open HICON can not be
loaded.
I have narrowed it down to GDIplus dll trying to create mask bitmap for
the
icon from stream (standard MFC serialization). This operation always
fails.
Here is my simple serialization code:

void CMyObject::Serialize(CArchive &ar)
{
CObject::Serialize(ar);

if( ar.IsStoring() )
{
ar << m_hIcon;
}
else
{
ar >> m_hIcon;

}
}

m_hIcon obviously is type of the HICON.

Does anyone has the same issue?
Thank you in advance for any help.
