Remarks

COM Signature

From textmgr.idl:

HRESULT IVsDropdownBarClient::GetEntryImage(
   [in] long iCombo,
   [in] long iIndex,
   [out] long *piImageIndex
);

GetImage will only be called if you specified ENTRY_IMAGE for the entry attributes of the given combo. There are two expected return codes from GetImage:

S_OK: Draw the glyph indicated in *piImageIndex. Use this for entries that should have a glyph.
S_FALSE: Set aside space for a glyph, but don't draw anything. Use this for entries that don't have a glyph but might have sibling entries in the same combo with glyphs.
Other: Some other failure occurred.

Glyphs in your image lists are assumed to be of the same height.
