Changing Embedded objects Icon

I am attempting to change an embedded objects icon after the item
has been embedded. What I would like to do is change the embedded
items display icon from the default object icon to 
something else(in my case a icon-sized thumbnail of an image).

To be more specific, I am embedding a graphic image. When
the image is first embedded, I use the default document
icon. After I load another image or maniuplate the image,
I would like to change the icon to that image and
not the default.

To this end, I call 		
	pDoc->UpdateAllItems(NULL,0L,NULL,DVASPECT_ICON);

to update the the icon when the document changes.

While my CMyServerSrvrItem::OnDrawEx does get called, the container
doesn't change the icon. 

I am presuming that sometime after
my OnDrawEx gets called that a CacheGlobalData with the correct
bitmap is going to happen.

What am I missing?

 thanks,
 jon

Take a look the code in COleChangeIconDialog. All you need to do is to 
create a metafile and call the client item's SetIconicMetafile function.
Then call its OnChange with DVASPECT_ICON flag to redraw the new icon.
