推荐答案

尝试
在应用程序中使用Shell ContextMenu [如何自定义WebBrowser控件的上下文菜单通过IDocHostUIHandler接口. [ ^ ]

Try
Use Shell ContextMenu in your applications[^]
How to customize the context menus of a WebBrowser control via the IDocHostUIHandler interface.[^]

通过在您的CEdit派生类中添加WM_CONTEXTMENU处理函数来覆盖CWnd :: OnContextMenu.在此处理程序中，您必须加载自己的弹出菜单，调用TrackPopupMenu并根据返回的ID调用菜单函数.

示例:

Override CWnd::OnContextMenu by adding a WM_CONTEXTMENU handler to your CEdit derived class. From within this handler, you must load your own popup menu, call TrackPopupMenu and call the menu functions according to the returned ID.

Example:

void CMyEdit::OnContextMenu(CWnd* /*pWnd*/, CPoint point)
{
    CMenu menu;
    VERIFY(menu.LoadMenu(IDR_MYEDIT_POPUP_MENU));
    CMenu *pSub = menu.GetSubMenu(0);
    // When right clicking on a control, the focus is sometimes not moved to it
    //  before calling this function.
    if (GetFocus() != this)
        SetFocus();

    // if opened by keyboard (not mouse)
    if (point.x < 0 && point.y < 0)					
    {
        CRect rect;
        GetWindowRect(rect);
        point.x = rect.left;
        point.y = rect.bottom;
    }
    int nCommand = pSub->TrackPopupMenuEx(
        TPM_LEFTALIGN | TPM_RIGHTBUTTON | TPM_VERPOSANIMATION | TPM_RETURNCMD | TPM_NONOTIFY, 
        point.x, point.y, 
        AfxGetMainWnd(), NULL); 
    switch (nCommand)
    {
    case ID_EDIT_COPY : OnCopy(); break;
    case ID_EDIT_CUT : OnCut(); break;
    }
}

为此，您必须拦截发送到编辑框的消息，您需要
用您自己的替换它的窗口过程.这种技术称为

您可以在此处了解有关子类化的信息: Windows子类化并与C ++类挂钩 [

For this you have to intercept messages that sent to the edit box you need to
replace its window procedure with your own. This technique called
subclassing.
