'Paste' in the context menu..this context menu also has the entries
added by me in separate handler..how can i remove this paste entry
from context menu..this apperas only when i right click the icon of my
nse and no where else.

The shell adds the "Paste" item if your drop target (as returned by CreateViewObject) returns any drop effect flags from its IDropTarget::DragEnter method. To prevent the "Paste" item from appearing, either return DROPEFFECT_NONE from DragEnter, or don't expose IDropTarget at all. However, I think it's much better to handle the shell's "Paste" command (by implementing IDropTarget::Drop) instead of adding your own menu item.
