如何为编辑框添加右键菜单

[wyjun1985]

在编辑框上右击时弹出的是系统的默认菜单，我像在这个菜单里再添加两个选项，如何才能实现呢？

}

BOOL CMenuEdit::OnCommand(WPARAM wParam, LPARAM lParam)

switch (LOWORD(wParam))

case EM_UNDO:
case WM_CUT:
case WM_COPY:
case WM_CLEAR:
case WM_PASTE:
return SendMessage(LOWORD(wParam));
case ME_SELECTALL:
return SendMessage (EM_SETSEL, 0, -1);
default:
return CEdit::OnCommand(wParam, lParam);
}
}
这样时更换了菜单。

谢谢楼上的回答，不过我没看懂什么意思？是初学者，能否说的详细点。谢谢啦！

在Edit父窗口的PreTranslateMessage里面去处理：

BOOL C**Dlg::PreTranslateMessage(MSG* pMsg) 
{
	if( WM_RBUTTONDOWN == pMsg->message )  //截获右键消息
	{
		int iID; 
		HWND hd=(HWND)::GetFocus();  //取得当前焦点窗口句柄
		iID=::GetDlgCtrlID(hd);      //得到当前焦点窗口的ID
		
		if( iID == IDC_EDIT1 ) //判断当前窗口是不是要加菜单的Edit窗口
		{ 
			CEdit * EditWnd = ( CEdit* ) GetDlgItem( iID ); //取得Edit的窗口指针
			
			CMenu *pMenu;
			
			CPoint pt;
			GetCursorPos( &pt );
			pMenu=new CMenu;
			
			pMenu->LoadMenu( IDR_MYEDITMENU );  //加载菜单资源
			CMenu *pMenuPop=pMenu->GetSubMenu(0); //一般弹出菜单是资源菜单的第一项
			pMenuPop->TrackPopupMenu( TPM_LEFTALIGN, pt.x, pt.y, this );
			delete pMenu;
		}
	}
    return CDialog::PreTranslateMessage(pMsg);
}

当然用二楼的方法 自己重写一个Edit也行。

俺常采用4楼的方法。
