Manually add Connection Point support after ATL Simple object wizard already run

After running ATL COM Simple object wizard without check "Connection Points", manual steps are need to add this support.

(1) myserver.h---IConnectionPointContainer/Impl, COM_MAP, IEvents

#include "ATLProject1_i.h"
#include "_IMyServerEvents_CP.h"


class ATL_NO_VTABLE CMyServer :
 public CComObjectRootEx<CComSingleThreadModel>,
 public CComCoClass<CMyServer, &CLSID_MyServer>,
 public IConnectionPointContainerImpl<CMyServer>,
 public CProxy_IMyServerEvents<CMyServer>,
 public IDispatchImpl<IMyServer, &IID_IMyServer, &LIBID_ATLProject1Lib, /*wMajor =*/ 1, /*wMinor =*/ 0>
{


BEGIN_COM_MAP(CMyServer)
 COM_INTERFACE_ENTRY(IMyServer)
 COM_INTERFACE_ENTRY(IDispatch)
 COM_INTERFACE_ENTRY(IConnectionPointContainer)
END_COM_MAP()

BEGIN_CONNECTION_POINT_MAP(CMyServer)
 CONNECTION_POINT_ENTRY(__uuidof(_IMyServerEvents))
END_CONNECTION_POINT_MAP()

(2)   .\atlproject1\atlproject1\atlproject1.vcxproj.filters -- need one include

    <ClInclude Include="ATLProject1_i.h">
      <Filter>Generated Files</Filter>
    </ClInclude>
    <ClInclude Include="_IMyServerEvents_CP.h">
      <Filter>Header Files</Filter>
    </ClInclude>
    <ClInclude Include="MyServer.h">
      <Filter>Header Files</Filter>
    </ClInclude>
  </ItemGroup>


(3).\atlproject1\atlproject1\atlproject1.vcxproj --- include .h for compiler
 

  <ItemGroup>
    <ClInclude Include="ATLProject1_i.h" />
    <ClInclude Include="dllmain.h" />
    <ClInclude Include="MyServer.h" />
    <ClInclude Include="Resource.h" />
    <ClInclude Include="stdafx.h" />
    <ClInclude Include="targetver.h" />
    <ClInclude Include="xdlldata.h" />
    <ClInclude Include="_IMyServerEvents_CP.h" />
  </ItemGroup>



(4)   .\atlproject1\atlproject1\atlproject1.idl  -- disinterface and coclass

library ATLProject1Lib
{
 importlib("stdole2.tlb");
 [
  uuid(1D071C81-6C67-458F-9B35-992DBAE162D8) // one of these are duplicate 
  uuid(118E250A-B298-4749-90D8-36C764237BA4)  
 ]
 dispinterface _IMyServerEvents
 {
  properties:
  methods:
 };
 [
  uuid(48A5B08F-ED8F-4F1F-8344-5F7C913FB895)  
 ]
 coclass MyServer
 {
  [default] interface IMyServer;
  [default, source] dispinterface _IMyServerEvents;
 };
};


Notes:
(n1) to user Connection point, Add Method to _IMyServerEvents (Class View Context Menu) e.g. signature CB(int data). 
Then Add->Connection point onto CMyServer Class (again Class View Ctx Menu) select _IMyS erverEvents in
 Source Interface List. Now there will be a function Fire_CB to fire COM Event into WPF client

(n2) MyServer.rgs need update ForceRemove {dispinterface _IMyServerEvents GUI in IDL} = s 'MyServer Class'

(n3) Content of  [project dir]\_IMyServerEvents_CP.h
#pragma once

using namespace ATL;

template 
class CProxy_IMyServerEvents : public IConnectionPointImpl
{
 // WARNING: This class may be regenerated by the wizard
