推荐答案

一种常见的方法是从MFC控件派生自己的类并使用 PreTranslateMessage 处理消息（未经测试）：

A common method would be deriving your own class from the MFC control and handling the message there using PreTranslateMessage (untested):

BOOL CMyComboBox::PreTranslateMessage(MSG* pMsg)
{
    return pMsg->message == WM_MOUSEWHEEL ? TRUE : CComboBox::PreTranslateMessage(pMsg);
}
