// NOTE: there is a problem with dxtrans.h missing from newer Microsoft DirectX SDKs (including March 2009)

// This header file is referenced only by qedit.h and not needed.
// Solution: add this pragma and these defines before the qedit.h inclusion:
#pragma include_alias( "dxtrans.h", "qedit.h" )

#include <qedit.h>
#include <atlbase.h>
// This used to work back when qedit.h still existed. The hacks
// served to prevent it from including the defunct dxtrans.h.

// We can use this fugly hack to still access the qedit.h interfaces.
// When this stops working, we'll have to just copy the relevant
