Disabling OLE drag/drop for CRichEditView

I'm writing an MDI prog and have tried tirelessly to catch or remove the "on drop" message of my CRichEditView's. I've implemented drag/drop to allow the user to open files that way, but it will only work when the drop target is outside of a view (in the frame)... Of course, when the target is within a view, the icon of the source is inserted..

I have tried to catch the WM_DROPFILES, but it appears this message is never sent during the operation in question..

Do you know how to catch the message sent when an external icon is dragged/dropped into a CRichEditView window?

You need to set the event mask for the RichEdit control to specify which notification mesages the control sends to its parent window.

Look into CRichEditCtrl::SetEventMask and the available event mask flags. Returning 0 from the EN_DROPFILES notification should do the trick.

Thanks for the tip codeplug. I attempted to look up the ENM_* flags from the MSVC online documentation, with no luck.
However, I am having difficulty applying what I've learned... The MSDN library says that a rich edit control's EN_DROPFILES message is sent in the form of a WM_NOTIFY message when it receives WM_DROPFILES.

Here's what I'm trying:
I added ENM_DROPFILES to my rich edit view's event mask. Then I called DragAcceptFiles(TRUE) in OnInitialUpdate() (I've tried it that way or as GetRichEditCtrl.DragAcceptFiles(TRUE).
I've message mapped ON_WM_DROPFILES(). The handler is
void OnDropFiles(HDROP hDropInfo);

Any further ideas? :)

Aha!

I figured it out. I added
ON_NOTIFY_REFLECT(EN_DROPFILES, OnDropFiles)
to my message map. Now I am catching the drop files message, but returning zero doesn't halt the insert of the icon! <: (

I don't know if I'll ever figure it out. At least I'm on the right path (somewhat).
