MFC project disable copy & paste on CEdit

tags: `mfc` `visual studio`

CMyEdit.h














#pragma once
#include "afxwin.h"

class CMyEdit : public CEdit
{
public:
	CMyEdit();   // standard constructor
	~CMyEdit();

protected:
	afx_msg LRESULT OnPaste(WPARAM wParam, LPARAM lParam);
	DECLARE_MESSAGE_MAP()

};

CMyEdit.pp
















#include "CMyEdit.h"


CMyEdit::CMyEdit(){}
CMyEdit::~CMyEdit(){}

BEGIN_MESSAGE_MAP(CMyEdit, CEdit)
	ON_MESSAGE(WM_PASTE, &CMyEdit::OnPaste)
END_MESSAGE_MAP()

LRESULT CMyEdit::OnPaste(WPARAM wParam, LPARAM lParam){
// Put any code here you want to execute when the user right clicks on the edit
// control. Just leave it blank to disable the menu
	return true;
}

把 edit 的 IDC_EDIT 使用上面新的 CMyEdit 來使用 Edit 欄位
IDC_EDIT 就是 UI 上 edit field 元件的 ID.

需要使用自訂的 CEdit 的 cpp 上面加上:







.h: (宣告)
CMyEdit m_myEditControl;

.cpp: (DoDataExchange function 加入)
DDX_Control(pDX, IDC_EDIT, m_myEditControl);
