How to handle CTRL V event in MFC CRichEditCtrl

I have created sample MFC application with only one rich edit control in it.
I want to handle CTRL V (keyboard paste) event for this edit control.
when I right click and check events in property, I don't see any event which can handle CTRL V.
I tried ENM_PROTECTED but no luck.

I remember that this controls handles Ctrl+V by itself. So you have to be more precise: What do you want to handle?

If you want to introduce your own code for the Paste you may add a PreTranslateMessage Handler to the View or Dialog. You can handle all Keyboard message there before it is handed out to the controls.

Thank you for the suggestion, xMRi.
I have tried it, and it works but still does not solve my exact purpose.
Below is the code that captures CTRL-V messages.

BOOL myRichEditCtrl::PreTranslateMessage(MSG* pMsg)
{
    if (GetKeyState(VK_CONTROL) & 0x8000 &&
        GetKeyState('V') & 0x8000 &&
        GetFocus() == this)
        {
	      //process messages here (keys ??) 
        } 
        return CRichEditCtrl::PreTranslateMessage(pMsg);
}

You can handle Ctrl-V keypress using Accelerators, this prevents the default paste behaviour and allows you to paste text of your choice into the Rich Edit Control instead.

The following code was tested with an MFC single dialog app with the name CMFCApplication4Dlg, but this should give you everything required to get it working in your application.

Here are the steps required below:

In resource.h add:

#define IDR_ACCELERATOR1                156
#define ID_RICH_CTRL_V                  1001

In .rc file add:

/////////////////////////////////////////////////////////////////////
//
// Accelerator
//

IDR_ACCELERATOR1 ACCELERATORS
BEGIN
    "V",            ID_RICH_CTRL_V,         VIRTKEY, CONTROL
END

In your dialog header add:

HACCEL m_hAccel;
afx_msg void OnRichCtrlV();
virtual BOOL PreTranslateMessage(MSG* pMsg);

In your dialog initilization add:

BOOL CMFCApplication4Dlg::OnInitDialog()
{
    m_hAccel = LoadAccelerators(AfxGetInstanceHandle(),
	    MAKEINTRESOURCE(IDR_ACCELERATOR1));
...

Add to the following to your BEGIN_MESSAGE_MAP:

ON_COMMAND(ID_RICH_CTRL_V, &CMFCApplication4Dlg::OnRichCtrlV)

And the associated method:

void CMFCApplication4Dlg::OnRichCtrlV()
{
    // Ctrl V was pressed handle here

	CWnd *hwnd = GetDlgItem(IDC_RICHEDIT21);
    hwnd->SetWindowTextW(L"Overide Pasted Text Here");
}

Add the following PreTranslateMessage:

BOOL CMFCApplication4Dlg::PreTranslateMessage(MSG* pMsg)
{
    if (m_hAccel)
    {
	    if (::TranslateAccelerator(m_hWnd, m_hAccel, pMsg))
	    {
		    return(TRUE);
	    }
    }

	return CDialog::PreTranslateMessage(pMsg);
}

After spending hours on Google, I finally found a piece of code.

MFC Cricheditctrl does not let the user override the OnKeyDown function directly. 
It is a protected member, so I have to create my own CrichEditCtrl, which inherits from Cricheditctrl, and then override OnKeyDown.
but I am still unable to handle CTRL V event.

class myRichEditCtrl : public CRichEditCtrl //derived from CWnd
{
  //override below function to handle key down event
  // this function is part of CWnd 
  afx_msg void OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags);
}
 
void myRichEditCtrl::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
   //process keys here
   if ( (nChar == 'v' ||  nChar == 'V') && (GetKeyState(VK_CONTROL) <0))
   {
      // still not working nChar value is 17 when I press ctrl V, Why ??
   }
   
   //call default if needed
    CRichEditCtrl::OnKeyDown(nChar, nRepCnt, nFlags);
}
