     Is there a way to get a palette out of a COleClientItem?  I am drawing 
     them, along with several bitmaps, and I want the bitmaps to use the 
     same palette.  The docs to Draw() state that it uses the metafile 
     representation of the object (of course), but don't mention palettes.  
     But, it doesn't appear that any palette is realized during drawing, 
     since OLE objects made from DIBs (bmps) are not drawn in their native 
     colors.
     
     (I'm using an OLE object for a window background.  Typical uses will 
     be bitmaps in several formats, plus Visio and AutoCad schematics.)

I've been trying to do this, too. The Ole documentation describes the member 
function GetColorSet in IViewObject. I've tried using this, but it always 
returns the SCODE OLE_E_BLANK.
