Re: How to catch keydown

Try this, and make sure that you are creating a CMyIPAddressCtrl not a
CIPAddressCtrl

///////////////////////////////////////// header file
#pragma once

// CMyIPAddressCtrl

class CMyIPAddressCtrl : public CIPAddressCtrl
{
 DECLARE_DYNAMIC(CMyIPAddressCtrl)

public:
 CMyIPAddressCtrl();
 virtual ~CMyIPAddressCtrl();

protected:
   virtual BOOL PreTranslateMessage(MSG* pMsg);
 DECLARE_MESSAGE_MAP()
};

///////////////////////////////////////// cpp file
// MyIPAddressCtrl.cpp : implementation file
//

#include "stdafx.h"
#include "IPControl.h"
#include "MyIPAddressCtrl.h"

IMPLEMENT_DYNAMIC(CMyIPAddressCtrl, CIPAddressCtrl)
CMyIPAddressCtrl::CMyIPAddressCtrl()
{
}

CMyIPAddressCtrl::~CMyIPAddressCtrl()
{
}

BEGIN_MESSAGE_MAP(CMyIPAddressCtrl, CIPAddressCtrl)
END_MESSAGE_MAP()

// CMyIPAddressCtrl message handlers

BOOL CMyIPAddressCtrl::PreTranslateMessage(MSG* pMsg)
{
   if (pMsg->message == WM_KEYDOWN)
   {
      TRACE("Key down\n");
   }
   else if (pMsg->message == WM_CHAR)
   {
      TRACE("CHAR\n");
   }

   return CIPAddressCtrl::PreTranslateMessage(pMsg);
}
