Since you only want to do this with your own application, what you can do is
activate the receiving window when it gets the OnDragEnter or OnDrop.

Here is a drag and drop listbox that I did, it activates the second window
when the mouse moves to the second instance.

Here is a snippet on how to activate the current window:
void COLEDragAndDropListBox::ActivateWindow()
{
   //get the parent of the control, should be the main dialog
   CWnd *pWnd = GetParent();
   if (pWnd)
   {
      pWnd->SetForegroundWindow();
      pWnd->BringWindowToTop();
      pWnd->SetActiveWindow();
   }
}

I have a dialog based MFC application which also supports drag and drop
from
a CTreeCtrl onto any other application that supports the drop of ASCII and
Unicode text. It also supports D&D og entries from this TreeCtrl to
another
instance of the same application.

D&D is via classes based on the standard COleDropSource, COleDataSource &
COleDropTarget functionality.

After the 'DoDragDrop' completes successfully, I would like transfer the
focus to the Window that just received that text of entry data.

Can anyone tell me how to get the handle of that target window and how to
then transfer the focus to it?

Many thanks.
