Hello,

I am trying to customise drag and drop operations in my CRichEditView derived object. Problem is, none of the drag and drop message handlers (OnDrop, OnDropFiles etc) get activated when a file is dropped into my application window ie. the drag and drop functions but I cannot control it.

I can control drag and drop operations from a CView derived class but not a CRichEditView derived class. Please enlighten.

Commented:
1). Write your own class derived from COleDropTarget.
    class CMyOleDropTarget : public COleDropTarget {...};

2). Override following member functions of COleDropTarget class:
  OnDragEnter(...)
  OnDragLeave(...)
  OnDragOver(...)
  OnDrop(...)
    These functions are responsible for drag & drop customization.

3). In your CRichEditView derived class add following member:
  CMyOleDropTarget m_myDropTarget;

4). In your CRichEditView derived class modify OnCreate()
    member function:
  CMyRichEditView::OnCreate(...)
  {
    ...
    m_myDropTarget.Register(this);
    ...
  }
