No WM_CONTEXTMENU for RichEdit after EM

Discussion:

No WM_CONTEXTMENU for RichEdit after EM_SETOLECALLBACK

Hello All

I have a RichEdit control which I have placed in a dialog. I provide a
custom context menu by catching the WM_CONTEXTMENU message for the RichEdit.
WM_COMMAND messages sent by clicking menu items are received and handled
within the control. This all seems to work OK.

However, I have now need some of the OLE functionality of the RichEdit so I
have retreived a IRichEditOleCallback object using the EM_SETOLECALLBACK
message. However, once I have done this, the WM_CONTEXTMENU message is never
sent to the RichEdit any more. I can get around this by providing a
IRichEditOleCallback::GetContextMenu method and creating the context menu in
there. This seems to work. However, whenever I then select a menu item from
the context menu, the WM_COMMAND message is sent to the parent dialog rather
than the RichEdit control itself. Is there any way I can change this
behaviour so that command messages are sent to the control as normal?

Thanks in advance.

Mark

WM_COMMAND messages are always sent to the parent of the control.

OK, then MFC must be routing them back to the control in the first case,
since I am handling them via the ON_COMMAND macro in the RichEdit control
class. Once I have called EM_SETOLECALLBACK however, the routing no longer
works, since the handler no longer gets called in the RichEdit and instead
the message goes to the parent dialog. Any idea how I can still have the
command messages still go to the control class since all my handling is
there at the moment and I don't really want to have to add it to each dialog
class just for the case where I need the OLE functionality?

Thanks.

Not really. I don't generally program in MFC.

Hi Mark ,

Yes, I agree that this magic should be done by MFC. I will discuss with
some MFC experts internally to see if we have any elegant workaround for
it. I will get back to you ASAP. Thanks.

Hi Mark,

Have you tried ON_CONTROL_REFLECT in your rich edit control's message map?

Also, can you send an email to ***@online.microsoft.com(remove "online.")
so that we can communicate more efficiently?

Thanks.

Hi Jeffrey

Yes, I have already tried ON_CONTROL_REFLECT. However, I still get the same
problem, in that the handler function specified in the macro is never called
and the message instead goes to the parent dialog.

Thanks.

Hi Mark,

Thank you for the feedback.

Without reproducing the problem, the analysis can only base on the guess.
Is it possible to create a little sample project to demonstrate this
behavior? Once we can reproduce it locally, we can analysis it better.

You may send the sample project to me at the email address I provided in
the last reply.

Thanks.
