I encountered this problem repeatedly and it was very difficult to query the information. I simply put it here for my friends to learn from.

Microsoft is so disgusting that it cannot easily add the right-click menu function item for formview or richeditctrl on dialog. After searching materials and using them, you need to use this method to achieve it:
Notes
1. The system command cannot appear in the right-click menu, for example, id_edit_undo/id_edit_copy/id_edit_paste/id_edit_cut/id_edit_selall. Otherwise, the message cannot be responded.
2. For menu items, message processing cannot be performed using oncommand. on_message must be used in message map and the good message function such as onmenuundo must be defined in the header file.
Begin_message_map (creferenceformview, cformview)
// {Afx_msg_map (creferenceformview)
On_message (id_menu_undo, onmenuundo)
On_message (id_menu_cut, onmenucut)
On_message (id_menu_copy, onmenucopy)
On_message (id_menu_paste, onmenupaste)
On_message (id_menu_clear, onmenuclear)
On_message (id_menu_select_all, onmenuselectall)
//} Afx_msg_map
End_message_map ()
3. You must call the oninitialupdate () function of formview or the oninitialdialog () function of dialog.
M_ctrlricheditreference.seteventmask (enm_mouseevents );
Indicates that the mouse event of richeditctrl is handled by the parent form.
4. Handle the following in the onnotify message of the parent form (formview or dialog:
Bool creferenceformview: onnotify (wparam, lparam, lresult * presult)
{
// Todo: add your specialized code here and/or call the base class
Key Aspect 1:
The richeditctrl sends the message "en_msgfilter" to the parent, now to get at which message has been reflected (because it cocould be a left click or a mouse move) we need to examine the message filter, So we cast lparam to msgfilter *
{
// If we get through here, we have trapped the right click event of the richeditctrl!
Cpoint point;
: Getcursorpos (& Point); // Where is the mouse?
Cmenu menu; // lets display out context menu :)
Uint dwselectionmade;
Verify (menu. loadmenu (idr_mnu_reference4re ));
Cmenu * pmenupopup = menu. getsubmenu (0 );
Assert (pmenupopup! = NULL );
Dwselectionmade = pmenupopup-> trackpopupmenu (tpm_leftalign implements TPM _ leftbutton implements TPM _ nonotify implements TPM _ returncmd ),
Point. X, point. Y, this
);

The upper floor only supports Right-click menu response, adding, how to respond to shortcuts, and passing messages down:
Bool cformviewrecordeditor: pretranslatemessage (MSG * PMSG)
{
// Todo: add your specialized code here and/or call the base class
If (PMSG-> message = wm_keydown)
{
Switch (PMSG-> wparam)
{
Case 0x41: // selete all
Case 0x46: // Ctrl + F
Case 0x56: // Ctrl + V:
Case 0x58: // cut
Case 0x43: // copy
Case 0x5a: // undo
Case 0x59: // redo
If (getkeystate (vk_control) & 0x80 ))
{
M_ctlricheditfulltext.sendmessage (PMSG-> message, PMSG-> wparam, PMSG-> lparam );
Return true;
}
Break;
}
} // End: If (PMSG-> message );
Return cformview: pretranslatemessage (PMSG );
}
All of the above Code You can only apply the effect to richeditctrl on formview or propertypage. To respond to the shortcut key for edit that appears in the parent form, use the following code:
Bool cppfieldeditnormal: pretranslatemessage (MSG * PMSG)
{
// Todo: add your specialized code here and/or call the base class
If (PMSG-> message = wm_keydown)
{
Switch (PMSG-> wparam)
{
Case 0x41: // selete all
Case 0x46: // Ctrl + F
Case 0x56: // Ctrl + V:
Case 0x58: // cut
Case 0x43: // copy
Case 0x5a: // undo
Case 0x59: // redo
If (getkeystate (vk_control) & 0x80) & (m_ctleditfieldvalue.m_hwnd = getfocus ()-> m_hwnd ))
{
// M_ctleditfieldvalue.sendmessage (PMSG-> message, PMSG-> wparam, PMSG-> lparam); // This method cannot respond correctly
//: Postmessage (m_ctleditfieldvalue.m_hwnd, PMSG-> message, PMSG-> wparam, PMSG-> lparam); // This method cannot respond correctly.
// M_ctleditfieldvalue.sendmessage (wm_command, (wparam) id_edit_paste, (lparam) 0); // This method cannot respond correctly
: Postmessage (m_ctleditfieldvalue.m_hwnd, wm_paste, (wparam) 0, (lparam) 0); // This method can respond correctly !!
}
Return true;
}
Break;
}
} // End: If (PMSG-> message );
